  1. The implications of psychological limitations for the ethics of climate change

    Kasperbauer, Tyler Joshua

    2016-01-01

    Most philosophers and psychologists who have explored the psychology of climate change have focused only on motivational issues - getting people to act on what morality requires of them. This is misleading, however, because there are other psychological processes directed not at motivation...... but rather our ability to grasp the implications of climate change in a general way - what Stephen Gardiner has called the 'grasping problem'. Taking the grasping problem as my departure point, I draw two conclusions from the relevant psychological literature: 1) ethicists and policy makers should focus less...

    Full Text Available Orientation: The relationship between authentic leadership, psychological capital, psychological climate and team commitment in a manufacturing organisation could have a significant impact on employee intention to quit.Research purpose: To determine the relationship between five positive organisational behaviour variables (authentic leadership, psychological capital, psychological climate and team commitment and their ultimate influence on an individual’s intention to quit. Thus, it is preceded by the determination of the structural invariance of the measurement instruments when applied to a South African sample.Justification for the study: The study sought to fill the gap in the literature in relation to understanding the effect of the relationship between psychological capital, authentic leadership, psychological climate and team commitment on the behaviour of employees in a manufacturing organisation and how this influences their decision to quit. Such a study has not previously been conducted in the South African manufacturing sector.Research design, approach and method: Utilising a non-experimental correlational approach, a self-administered composite questionnaire consisting of five psychological scales was distributed to 204 employees in the junior to senior management level at a global tyre manufacturing organisation in South Africa. Multivariate data analysis included the structural equation modelling.Main findings: There is a significantly strong positive relationship between authentic leadership, psychological capital, psychological climate and team commitment. Authentic leadership has a significant influence on psychological capital and psychological climate. This results in a positive impact on organisational commitment, leading to employees’ intention to quit.Practical/managerial implications: Manufacturing organisations need to develop and implement collaborative leadership intervention strategies aimed at improving

    Full Text Available Psychological effects of climate change constitute one of the subjects of study of ecological psychology. Ecological psychology is formed and developed at the junction of ecology, different directions of psychology, psychotherapy, pedagogy, philosophy and other disciplines. The article is devoted to review those areas of psychological research, which consider the human psyche in the logic of interac¬tion with the environment. As a result, we hope to answer the fundamental ques¬tion of whether ecological psychology may be regarded as an independent area of psychological research, which has its object and methods that distinguish it from other areas of psychological theory and practice.

  6. The psychological distance of climate change.

    2012-06-01

    Avoiding dangerous climate change is one of the most urgent social risk issues we face today and understanding related public perceptions is critical to engaging the public with the major societal transformations required to combat climate change. Analyses of public perceptions have indicated that climate change is perceived as distant on a number of different dimensions. However, to date there has been no in-depth exploration of the psychological distance of climate change. This study uses a nationally representative British sample in order to systematically explore and characterize each of the four theorized dimensions of psychological distance--temporal, social, and geographical distance, and uncertainty--in relation to climate change. We examine how each of these different aspects of psychological distance relate to each other as well as to concerns about climate change and sustainable behavior intentions. Results indicate that climate change is both psychologically distant and proximal in relation to different dimensions. Lower psychological distance was generally associated with higher levels of concern, although perceived impacts on developing countries, as an indicator of social distance, was also significantly related to preparedness to act on climate change. Our findings clearly point to the utility of risk communication techniques designed to reduce psychological distance. However, highlighting the potentially very serious distant impacts of climate change may also be useful in promoting sustainable behavior, even among those already concerned. © 2011 Society for Risk Analysis.

    Human behaviour is integral not only to causing global climate change but also to responding and adapting to it. Here, we argue that psychological research should inform efforts to address climate change, to avoid misunderstandings about human behaviour and motivations that can lead to ineffective or misguided policies. We review three key research areas: describing human perceptions of climate change; understanding and changing individual and household behaviour that drives climate change; and examining the human impacts of climate change and adaptation responses. Although much has been learned in these areas, we suggest important directions for further research.

  11. Psychological implications in ENT diseases.

    2009-06-01

    We are sometimes faced with psychic derangement or overlay in some of the ENT diseases and the link between patient's psyche and any ENT disease at times becomes signifi cant and troublesome. The conditions in the fi eld between otorhinolaryngology and psychiatry can be classifi ed as psychiatric symptoms resulting from ENT diseases or interventions and those expressing themselves as ENT symptoms due to mental ailment. The former include hearing impairment, dizziness, tinnitus, choked airway, bad oral breath, stuffy nose, traumatic interventions and external nasal deformities. The later include exaggerated and diminished pharyngeal refl ex, globus hystericus, speech disorders, vasomotor rhinitis, nose picking, choked feeling, dizziness and headache. At times diseases originate in the human mind (consciousness), causing negative thoughts like jealousy, anger, and depression due to frustration. p ]A healthy mind in a healthy body generates sound and noble thoughts. Once a healthy body-mind relationship is established, we can be reasonably sure that greater happiness and success is within our reach. Patient seeking help from ENT surgeons to change their physical appearances and or function may not understand that the ultimate goal of surgery is to bring about psychological change by modifying the physical change, which is important aspect in septorhinoplastic surgery. At times patients asking for corrective rhinoplasty for minor external nasal deformities may have underlying psychological disturbance and use even slight external nasal deformity as scapegoat for psychological upset. Males are more diffi cult patients psychologically for any facial cosmetic surgery. These days some patients read about their diseases or treatment on the Internet and get more confused and psychologically disturbed due to rare causes of their illness, rare complications and diversity of treatment available.

  14. Psychological implications of admission to critical care.

    Science.gov (United States)

    Pattison, Natalie

    Admission to critical care can have far-reaching psychological effects because of the distinct environment. Critical care services are being re-shaped to address long-term sequelae, including post-traumatic stress disorder, anxiety and depression. The long-term consequences of critical illness not only cost the individual, but also have implications for society, such as diminished areas of health-related quality-of-life in sleep, reduced ability to return to work and enjoy recreational activities (Audit Commission, 1999; Hayes et al, 2000). The debate around the phenomenon of intensive care unit (ICU) syndrome is discussed with reference to current thinking. After critical care, patients may experience amnesia, continued hallucinations or flashbacks, anxiety, depression, and dreams and nightmares. Nursing care for patients while in the critical care environment can have a positive effect on psychological well-being. Facilitating communication, explaining care and rationalizing interventions, ensuring patients are oriented as to time and place, reassuring patients about transfer, providing patients,where possible, with information about critical care before admission and considering anxiolytic use, are all practices that have a beneficial effect on patient care. Follow-up services can help patients come to terms with their experiences of critical illness and provide the opportunity for them to access further intervention if desired. Working towards providing optimal psychological care will have a positive effect on patients' psychological recovery and may also help physical recuperation after critical care.

  16. Climatic implications of ice microphysics

    Liou, K.N. [Univ. of Utah, Salt Lake City, UT (United States)

    1995-09-01

    Based on aircraft measurements of mid-latitude cirrus clouds, ice crystal size distribution and ice water content (IWC) are shown to be dependent on temperature. This dependence is also evident from the theoretical consideration of ice crystal growth. Using simple models of the diffusion and accretion growth of ice particles, the computed mean ice crystal size and IWC compare reasonably well with the measured mean values. The temperature dependence of ice crystal size and IWC has important climatic implications in that the temperature field perturbed by external radiative forcings, such as greenhouse warming, can alter the composition of ice crystal clouds. Through radiative transfer, ice microphysics can in turn affect the temperature field. Higher IWC would increase cloud solar albedo and infrared emissivity, while for a given IWC, larger crystals would reduce cloud albedo and emissivity. The competing effects produced by greenhouse temperature perturbations via ice micro-physics and radiation interactions and feedbacks are assessed by a one-dimensional radiative-convective climate model that includes an advanced radiation parameterization program. 3 figs.

    2016-09-01

    The recent Paris Agreement to limit greenhouse gas emissions, adopted by 195 nations at the 2015 United Nations Climate Change Conference, signaled unprecedented commitment by world leaders to address the human social aspects of climate change. Indeed, climate change increasingly is recognized by scientists and policymakers as a social issue requiring social solutions. However, whereas psychological research on intrapersonal and some group-level processes (e.g., political polarization of climate beliefs) has flourished, research into other social processes-such as an understanding of how nonpartisan social identities, cultural ideologies, and group hierarchies shape public engagement on climate change-has received substantially less attention. In this article, we take stock of current psychological approaches to the study of climate change to explore what is "social" about climate change from the perspective of psychology. Drawing from current interdisciplinary perspectives and emerging empirical findings within psychology, we identify four distinct features of climate change and three sets of psychological processes evoked by these features that are fundamentally social and shape both individual and group responses to climate change. Finally, we consider how a more nuanced understanding of the social underpinnings of climate change can stimulate new questions and advance theory within psychology. © The Author(s) 2016.

    2015-12-01

    In 2015, the University of Queensland and edX launched a Massive Open Online Course (MOOC), 'Making Sense of Climate Science Denial.' The MOOC debunked approximately 50 common climate myths using elements of both physical science and psychology. Students learned how to recognise the social and psychological drivers of climate science denial, how to better understand climate change, how to identify the techniques and fallacies that climate myths employ to distort climate science, and how to effectively debunk climate misinformation. Contributors to the website Skeptical Science delivered the lectures, which were reinforced via interviews with climate science and psychology experts. Over 15,000 students from 167 countries enrolled in the course, and student feedback was overwhelmingly positive. This MOOC provides a model for effective climate science education.

    Tindall, J. A.; Moran, E. H.

    2008-12-01

    Energy of weather systems greatly exceeds energy produced and used by humans. Variation in this energy causes climate variability potentially resulting in local, national, and/or global catastrophes beyond our ability to deter the loss of life and economic destabilization. Large scale natural disasters routinely result in shortages of water, disruption of energy supplies, and destruction of infrastructure. The resulting unforeseen and disastrous events occurring beyond national emergency preparation, as related to climate variability, could insight civil unrest due to dwindling and/or inaccessible resources necessary for survival. Lack of these necessary resources in impacted countries often leads to wars. Climate change coupled with population growth, which exposes more of the population to potential risks associated with climate and environmental change, demands faster technological response. Understanding climate/associated environmental changes, the relation to human activity and behavior, and including this in national and international emergency/security management plans would alleviate shortcomings in our present and future technological status. The scale of environmental change will determine the potential magnitude of civil unrest at the local, national, and/or global level along with security issues at each level. Commonly, security issues related to possible civil unrest owing to temporal environmental change is not part of a short and/or long-term strategy, yet recent large-scale disasters are reminders that system failures (as in hurricane Katrina) include acknowledged breaches to individual, community, and infrastructure security. Without advance planning and management concerning environmental change, oncoming and climate related events will intensify the level of devastation and human catastrophe. Depending upon the magnitude and period of catastrophic events and/or environmental changes, destabilization of agricultural systems, energy supplies, and

    Full Text Available Climate change presents a great importance in all sectors of the economy, but the agricultural sector is directly influenced by them. These changes have different causes and effects, but the agriculture is known to be a strategic and dynamic sector, which is considered also difficult and a priority of the economy. The higher crop yields guarantee prosperity, economic and financial growth for many countries in the world. The paper aims is to develop an overview on the implications of climate changes in agriculture over the last few years in Europe.

    Being a parent is deeply demanding and one of the most important events in life; parents experience the deepening of human relationships with their partner, within their families, and in society, and moreover the fundamental relationship between parent and child. Every medical, social, and political effort must be made to prevent infertility but also to offer infertile couples the best diagnostic and therapeutic paths. Understanding the suffering of the couple and their families prevents and helps ease the possible psychological and social complications of infertility. Therefore, infertility concerns not only biomedical sciences but also psychological and social ones-ethics and law-in their combined efforts to identify areas of understanding and of research for solutions while respecting the dignity of the couple and unborn child. The Catholic Church offers an ongoing contribution through dialogue in looking for ethical principles guiding scientific and medical research respectful of the true life of human beings. © 2013.

    2017-04-01

    The paper discusses how the condition of crossed-eyes affects a baby's eye contact with mother and potentially results in the loss of a vital emotional connection with her during the earliest days of life. This loss may contribute to a rupture that arrests emotional development at a deep psychic level. It is suggested that, in the same way as premature separation, the rupture can precipitate a 'fusional complex', a defence that develops to protect the infant against psychotic anxieties. The paper proposes that psychological development atrophies in this place and creates a blind spot. These ideas are explored through analytic theory and developmental literature. The dreams of a patient and his art are used to illustrate a 10-year 'alchemical' process of bringing repressed material into consciousness and transformation. Healing the psychological wounds of deficits in early eye contact may be found to bring sight to a blind spot that was created by the nature of the condition itself. © 2017, The Society of Analytical Psychology.

  11. Epigenetics and its implications for Psychology.

    2013-02-01

    Epigenetics is changing the widely accepted linear conception of genome function by explaining how environmental and psychological factors regulate the activity of our genome without involving changes in the DNA sequence. Research has identified epigenetic mechanisms mediating between environmental and psychological factors that contribute to normal and abnormal behavioral development. the emerging field of epigenetics as related to psychology is reviewed. the relationship between genes and behavior is reconsidered in terms of epigenetic mechanisms acting after birth and not only prenatally, as traditionally held. Behavioral epigenetics shows that our behavior could have long-term effects on the regulation of the genome function. In addition, epigenetic mechanisms would be related to psychopathology, as in the case of schizophrenia. In the latter case, it would be especially relevant to consider epigenetic factors such as life adversities (trauma, disorganized attachment, etc.) as related to its clinical manifestations, rather than genetic factors. Moreover, epigenetics implies overcoming classical dualist dichotomies such as nature-nurture, genotype-phenotype or pathogenesis-pathoplasty. In general, it can be stated that behavior and environment will finally take on a leading role in human development through epigenetic mechanisms.

    2015-12-01

    A frequent suggestion to increase individuals' willingness to take action on climate change and to support relevant policies is to highlight its proximal consequences, that is, those that are close in space and time. But previous studies that have tested this proximizing approach have not revealed the expected positive effects on individual action and support for addressing climate change. We present three lines of psychological reasoning that provide compelling arguments as to why highlighting proximal impacts of climate change might not be as effective a way to increase individual mitigation and adaptation efforts as is often assumed. Our contextualization of the proximizing approach within established psychological research suggests that, depending on the particular theoretical perspective one takes on this issue, and on specific individual characteristics suggested by these perspectives, proximizing can bring about the intended positive effects, can have no (visible) effect or can even backfire. Thus, the effects of proximizing are much more complex than is commonly assumed. Revealing this complexity contributes to a refined theoretical understanding of the role that psychological distance plays in the context of climate change and opens up further avenues for future research and for interventions.

    The present study is concerned with cultural diversity climate at school and how it relates to acculturation orientations and psychological school adjustment of early adolescent immigrants. Specifically, the distinct role of two types of diversity policy is investigated, namely (a) fostering equality and inclusion and (b) acknowledging cultural pluralism. Longitudinal multilevel analyses based on 386 early adolescent immigrant students (Mage  = 10.49 years) in 44 ethnically heterogeneous classrooms in Germany revealed that the manifestations of both types of policies promote psychological school adjustment (i.e., better well-being and fewer psychological and behavioral problems) at the individual level. However, they differ in their effects on acculturation orientations. At the classroom level, equality and inclusion promote assimilation. Implications for research and educational practice are discussed. © 2016 The Authors. Child Development © 2016 Society for Research in Child Development, Inc.

    Despite increasing interest in supervision as a leverage point for bolstering public mental health services, the potential influence of supervisory alliance on organizations and direct service providers remains understudied, particularly in the context of supporting evidence-based treatment (EBT) use. This study examined agreement and discrepancy between supervisor and clinician ratings of alliance associated with clinicians' perceptions of psychological climate and emotional exhaustion. Results indicated that discrepancies in alliance ratings were common and associated with clinicians' perceptions of psychological climate. These findings have important implications for collaboration among supervisors and clinicians within a community mental health organizational context and the provision of EBTs.

    This year's applicants to medical school took a newly revised version of the Medical College Admission Test. Unlike applicants in the past, they were asked to demonstrate their knowledge and use of concepts commonly taught in introductory psychology courses. The new Psychological, Social, and Biological Foundations of Behavior Test asked applicants to demonstrate the ways in which psychological, social, and biological factors influence perceptions and reactions to the world; behavior and behavior change; what people think about themselves and others; the cultural and social differences that influence well-being; and the relationships among social stratification, access to resources, and well-being. Building from the classic biopsychosocial model, this article provides the rationale for testing psychology concepts in application to medical school. It describes the concepts and skills that the new exam tests and shows how they lay the foundation for learning in medical school about the behavioral and sociocultural determinants of health. This article discusses the implications of these changes for undergraduate psychology faculty and psychology curricula as well as their importance to the profession of psychology at large.

    2014-09-01

    Full Text Available Authentic leadership has been purported to influence psychological well-being through its impact on work climate. Using a sample of 406 nurses, a time-lagged study design was employed to determine the mediational role of work climate in explaining the impact of authentic leadership. Two self-reported questionnaires were completed to ascertain: (1 authentic leadership; and (2 work climate at baseline. In addition, nurses completed a measure to determine their level of psychological well-being at work at the 6 month time period. A mediation analysis with the use of a bootstrapping technique reveals that work climate mediates the relationship between authentic leadership and psychological well-being at work. These findings indicate that authentic leadership impacts the work climate in a positive manner; thereby, increasing levels of psychological well-being at work. We discuss theoretical and practical implications of the findings for future research as well as outline some limitations.

    This theoretical research paper refers to the psychological consequences ofhypospadias, a male congenital deficiency of the urethra. Hypospadias is defined as an abnormal opening of the urethra on the underside of the penis and is a frequently found malformation with an incidence of 1 per 300 males. This malformation affects one of the most personal parts of the male anatomy and its psychological repercussions are undeniable. The vast majority of studies concerning this condition are found in the medical domain: surgical and pediatric urology and endocrynology. The difficulty in finding data about psychological implications of hypospadias, along with the lack of opportunities for discussing it was an objective to contribute a modest advancement in the field of psychology. Because of the fact that hypospadias is a psychological condition as well as a physical one, this theoretical paper discusses the influenceses of the condition on the patient's psychosocial (in the view of E. H. Erikson's theory) and psychosexual development (relation to the object theory of O. F. Kernberg).

    Research on psychological safety climate has primarily focused on its salutary effects on group risk-taking behaviors. We developed a group-level dual-pathway model in which psychological safety climate also exerts a simultaneous negative effect on risk-taking behaviors by diminishing group average work motivation. In a field survey, we found that psychological safety climate was positively related to group learning behavior and voice through a reduction in group average fear of failure but n...

    There is little understanding of how climate change will impact potamodromous freshwater fishes. Since the mid 1970s, a decline in annual rainfall in south-western Australia (a globally recognized biodiversity hotspot) has resulted in the rivers of the region undergoing severe reductions in surface flows (ca. 50%). There is universal agreement amongst Global Climate Models that rainfall will continue to decline in this region. Limited data are available on the movement patterns of the endemic freshwater fishes of south-western Australia or on the relationship between their life histories and hydrology. We used this region as a model to determine how dramatic hydrological change may impact potamodromous freshwater fishes. Migration patterns of fishes in the largest river in south-western Australia were quantified over a 4 year period and were related to a number of key environmental variables including discharge, temperature, pH, conductivity and dissolved oxygen. Most of the endemic freshwater fishes were potamodromous, displaying lateral seasonal spawning migrations from the main channel into tributaries, and there were significant temporal differences in movement patterns between species. Using a model averaging approach, amount of discharge was clearly the best predictor of upstream and downstream movement for most species. Given past and projected reductions in surface flow and groundwater, the findings have major implications for future recruitment rates and population viabilities of potamodromous fishes. Freshwater ecosystems in drying climatic regions can only be managed effectively if such hydro-ecological relationships are considered. Proactive management and addressing existing anthropogenic stressors on aquatic ecosystems associated with the development of surface and groundwater resources and land use is required to increase the resistance and resilience of potamodromous fishes to ongoing flow reductions. © 2013 John Wiley & Sons Ltd.

    This research explores the linking mechanisms and conditional processes underlying the relationship between psychological voice climate and individual change readiness. In accordance with the social identity theory, we argued that normative commitment would mediate the relationship between psychological voice climate and individual change readiness; furthermore, work engagement would moderate the proposed indirect effect. Two-wave survey data were collected from 187 full-time employees in a government-owned institute of research and development and were adopted for moderated mediation analysis. The results showed that normative commitment mediates the relationship between psychological voice climate and individual change readiness. Furthermore, work engagement strengthens the effect of psychological voice climate on individual change readiness in an indirect manner via normative commitment. Based on the findings, the theoretical implications and practical suggestions were discussed.

    Pristine inner experience is that which is directly present in awareness before it is distorted by attempts at observation or interpretation. Many psychological methods, including most introspective methods, attempt to measure some aspect of pristine inner experience (thoughts, feelings, mental imagery, sensations, etc.). We believe, however, that these methods produce unspecifiable combinations of pristine inner experience, beliefs about the self, beliefs about what inner experience should be like, inaccurate recollections, miscommunications, and other confounding influences. We argue that descriptive experience sampling (DES) can produce high fidelity descriptions of pristine inner experience. These descriptions are used to create idiographic profiles, carefully crafted, in-depth characterizations of the pristine inner experience of individuals. We believe these profiles, because they are built from moments apprehended via a method that confronts the challenges inherent in examining inner experience, are uniquely valuable in advancing the science of inner experience and psychology broadly. For example, DES observations raise important questions about the veracity of results gathered via questionnaires and other introspective methods, like casual introspection. DES findings also provide high fidelity phenomenological data that can be useful for those developing psychological theories, such as theories of emotional processing. Additionally, DES procedures may allow clinicians and clients to practice valuable skills, like bracketing presuppositions and attending to internal experiences. This paper will describe difficulties inherent in the study of pristine inner experience and discuss implications of high fidelity descriptions of pristine inner experience for psychological research, theory development, and clinical practice.

    Watson, Robert T.; Patz, Jonathan; Gubler, Duane J.; Parson, Edward A.; Vincent, James H.

    2005-07-01

    This paper reviews the background that has led to the now almost-universally held opinion in the scientific community that global climate change is occurring and is inescapably linked with anthropogenic activity. The potential implications to human health are considerable and very diverse. These include, for example, the increased direct impacts of heat and of rises in sea level, exacerbated air and water-borne harmful agents, and - associated with all the preceding - the emergence of environmental refugees. Vector-borne diseases, in particular those associated with blood-sucking arthropods such as mosquitoes, may be significantly impacted, including redistribution of some of those diseases to areas not previously affected. Responses to possible impending environmental and public health crises must involve political and socio-economic considerations, adding even greater complexity to what is already a difficult challenge. In some areas, adjustments to national and international public health practices and policies may be effective, at least in the short and medium terms. But in others, more drastic measures will be required. Environmental monitoring, in its widest sense, will play a significant role in the future management of the problem. (Author)

    This review of literature focuses on the influence of psychological work climate and job satisfaction on nurses’ turnover intentions. More specifically, this review aims to explain the influence of the primary dimensions of psychological work climate - job characteristics, role characteristics, leadership characteristics, teamwork characteristics and organizational characteristics - on nurses’ organizational and occupational turnover intentions. Furthermore, this review aims to explain the role of job satisfaction as a potential mediator in the relationship between psychological work climate dimensions and both organizational and occupational turnover intentions among nurses. More specifically, the mechanism by which an individual goes from having negative perceptions of psychological work climate to having turnover intentions is introduced. The review concludes by revealing evaluation and intervention practices that may facilitate the implementation of continuous improvement processes aimed to enhance nurses’ perceptions of the psychological work climate and job satisfaction.

  20. Ideology and community social psychology: theoretical considerations and practical implications.

    Montenegro, Marisela

    2002-08-01

    This paper addresses the importance of the concept of ideology in community work. The implications of a Marxist approach to ideology in community practice are analyzed in terms of the concepts of problematization (P. Freire, 1979) and consciousness-raising (J. Barreiro, 1976), illustrating the point with some examples. The traditional Marxist perspective is also examined in relation to the perspectives of social constructionism (I. Ibáñez, 1996), cultural studies (A. McRobbie, 1992), post-Marxism (E. Laclau & C. Mouffe, 1985), and feminism (D. Haraway, 1991). It is argued that the concepts of hegemony and habitus (P. Bourdieu, 1985) can be useful to community social psychology theory and practice. A "situated perspective"--in which it is possible to dialogue from different "subject positions," and articulate transformation and political action--is argued. The implications of this shifting in the concept of ideology by means of theoretical developments outside social communitypsychology can help to define the external (outside) agent's position in community practice.

    Climate change is an emerging challenge linked to negative outcomes for the environment and human health. Since the 1960s, there has been a growing recognition of the need to address climate change and the impact of greenhouse gas emissions implicated in the warming of our planet. There are also deleterious health outcomes linked to complex climate changes that are emerging in the 21st century. This article addresses the social justice issues associated with climate change and human health and discussion of climate justice. Discussion paper. A literature search of electronic databases was conducted for articles, texts, and documents related to climate change, climate justice, and human health. The literature suggests that those who contribute least to global warming are those who will disproportionately be affected by the negative health outcomes of climate change. The concept of climate justice and the role of the Mary Robinson Foundation-Climate Justice are discussed within a framework of nursing's professional responsibility and the importance of social justice for the world's people. The nursing profession must take a leadership role in engaging in policy and advocacy discussions in addressing the looming problems associated with climate change. Nursing organizations have adopted resolutions and engaged in leadership roles to address climate change at the local, regional, national, and global level. It is essential that nurses embrace concepts related to social justice and engage in the policy debate regarding the deleterious effects on human health related to global warming and climate change. Nursing's commitment to social justice offers an opportunity to offer significant global leadership in addressing the health implications related to climate change. Recognizing the negative impacts of climate change on well-being and the underlying socioeconomic reasons for their disproportionate and inequitable distribution can expand and optimize the profession's role

Gaining an understanding of the range of potential effects that climate change could have on immune function will be of considerable importance, particularly for child health, but has, as yet, received minimal research attention. We postulate several mechanisms whereby climate change sensitive exposures and conditions will subtly impair aspects of the human immune response, thereby altering the distribution of vulnerability within populations—particularly for children—to infection and disease. Key climate change-sensitive pathways include under-nutrition, psychological stress and exposure to ambient ultraviolet radiation, with effects on susceptibility to infection, allergy and autoimmune diseases. Other climate change sensitive exposures may also be important and interact, either additively or synergistically, to alter health risks. Conducting directed research in this area is imperative as the potential public health implications of climate change-induced weakening of the immune system at both individual and population levels are profound. This is particularly relevant for the already vulnerable children of the developing world, who will bear a disproportionate burden of future adverse environmental and geopolitical consequences of climate change.

    2017-10-01

    Why do people sing to babies? Human infants are relatively altricial and need their parents' attention to survive. Infant-directed song may constitute a signal of that attention. In Prader-Willi syndrome (PWS), a rare disorder of genomic imprinting, genes from chromosome 15q11-q13 that are typically paternally expressed are unexpressed, which results in exaggeration of traits that reduce offspring's investment demands on the mother. PWS may thus be associated with a distinctive musical phenotype. We report unusual responses to music in people with PWS. Subjects with PWS ( N = 39) moved more during music listening, exhibited greater reductions in heart rate in response to music listening, and displayed a specific deficit in pitch-discrimination ability relative to typically developing adults and children ( N = 589). Paternally expressed genes from 15q11-q13, which are unexpressed in PWS, may thus increase demands for music and enhance perceptual sensitivity to music. These results implicate genomic imprinting in the psychology of music, informing theories of music's evolutionary history.

    Titan's landscape is profoundly shaped by its atmosphere and comparable in magnitude perhaps with only the Earth and Mars amongst the worlds of the Solar System. Like the Earth, climate dictates the intensity and relative roles of fluvial and aeolian activity from place to place and over geologic time. Thus Titan's landscape is the record of climate change. We have investigated three broad classes of Titan climate evolution hypotheses (Steady State, Progressive, and Cyclic), regulated by the role, sources, and availability of methane. We favor the Progressive hypotheses, which we will outline here, then discuss their implication for habitability.

    The Köppen-Geiger climate classification has been used for over a century to delineate climate types across the globe. As it was developed to mimic the distribution of vegetation, it may provide a useful surrogate for making projections of the future distribution of vegetation, and hence resultant hydrological implications, under climate change scenarios. This paper developed projections of the Köppen-Geiger climate types covering the Australian continent for a 2030 and 2050 climate relative to a 1990 historical baseline climate using 17 Global Climate Models (GCMs) and five global warming scenarios. At the highest level of classification for a +2.4 °C future climate (the upper limit projected for 2050) relative to the historical baseline, it was projected that the area of the continent covered by - tropical climate types would increase from 8.8% to 9.1%; - arid climate types would increase from 76.5% to 81.7%; - temperate climate types would decrease from 14.7% to 9.2%; - cold climate types would decrease from 0.016% to 0.001%. Previous climate change impact studies on water resources in Australia have assumed a static vegetation distribution. If the change in projected climate types is used as a surrogate for a change in vegetation, then the major transition in climate from temperate to arid in parts of Australia under a drier future climate could cause indirect effects on water resources. A transition from annual cropping to perennial grassland would have a compounding effect on the projected reduction in recharge. In contrast, a transition from forest to grassland would have a mitigating effect on the projected reduction in runoff.

In contrast, a transition from forest to grassland would have a mitigating effect on the projected reduction in runoff.

  15. The Psychology of Schizophrenia: Implications for Biological and Psychotherapeutic Treatments.

    2016-08-01

    The focus on recent advances in the neurobiology of schizophrenia has pushed aside the psychological understanding of the person with schizophrenia for several decades. However, a useful functional psychology of schizophrenia (in distinction to a psychological approach to symptoms) remains clinically important for several reasons: it is a core part of the bio-psycho-social formulation; it helps us understand and connect with persons with schizophrenia; and it provides a framework by which to organize our treatment efforts (both psychotherapeutic and particularly biological), which can improve adherence and outcomes. A coherent psychological model (the deficit model) based on object relations theory best explains all the biological, psychological, clinical, and sociocultural factors relevant to the understanding and treatment of persons with schizophrenia. A better understanding of a coherent psychology of persons with schizophrenia and provision of psychotherapies improves both the biological and psychotherapeutic treatment of persons with schizophrenia.

    Energy, water and land are scarce resources, critical to humans. Developments in each affect the availability and cost of the others, and consequently human prosperity. Measures to limit greenhouse gas concentrations will inevitably exact dramatic changes on energy and land systems and in turn alter the character, magnitude and geographic distribution of human claims on water resources. We employ the Global Change Assessment Model (GCAM), an integrated assessment model to explore the interactions of energy, land and water systems in the context of alternative policies to limit climate change to three alternative levels: 2.5 Wm-2 (445 ppm CO2-e), 3.5 Wm-2 (535 ppm CO2-e) and 4.5 Wm-2 (645 ppm CO2-e). We explore the effects of two alternative land-use emissions mitigation policy options—one which taxes terrestrial carbon emissions equally with fossil fuel and industrial emissions, and an alternative which only taxes fossil fuel and industrial emissions but places no penalty on land-use change emissions. We find that increasing populations and economic growth could be anticipated to almost triple demand for water for agricultural systems across the century even in the absence of climate policy. In general policies to mitigate climate change increase agricultural demands for water still further, though the largest changes occur in the second half of the century, under both policy regimes. The two policies examined profoundly affected both the sources and magnitudes of the increase in irrigation water demands. The largest increases in agricultural irrigation water demand occurred in scenarios where only fossil fuel emissions were priced (but not land-use change emission) and were primarily driven by rapid expansion in bioenergy production. In these scenarios water demands were large relative to present-day total available water, calling into question whether it would be physically possible to produce the associated biomass energy. We explored the potential of improved

    Full Text Available The article regards the structure of the notion "school structure". The traditionally singled out components of school climate — structure and culture — are amended by the notion of an "individual", which becomes central for the concept of school security and in fact takes a domineering position in estimation and correction of school climate. The article discusses the need in elaboration of a balanced model of a school climate, able to take into account three main constituents: structural, cultural and individual.

  1. Examining the temporal relationship between psychological climate, work attitude, and staff turnover.

    Science.gov (United States)

    Garner, Bryan R; Hunter, Brooke D

    2013-02-01

    Relative to the broader industrial-organizational (I-O) psychology field, research on the turnover of substance use disorder (SUD) treatment staff is in its infancy. Despite its long and rich history, recent reviews of the turnover literature within I-O psychology have noted that there remains considerable room for improvement. In particular, recommendations have been made for research that considers time in the turnover process and explores more distal causes of staff turnover. Addressing these gaps, this article examined the temporal relationship between latent measures of psychological climate, work attitude, and staff turnover. Using data from 95 SUD treatment staff clustered within 29 treatment organizations, multilevel discrete-time survival analyses revealed that a latent measure of work attitude (e.g., job satisfaction, pay satisfaction, turnover intentions) fully mediated the temporal relationship between latent measures of psychological climate (e.g., supervisor support, coworker support, role conflict) and subsequent staff turnover.

    2017-07-01

    Safety climate research has reached a mature stage of development, with a number of meta-analyses demonstrating the link between safety climate and safety outcomes. More recently, there has been interest from systems theorists in integrating the concept of safety culture and to a lesser extent, safety climate into systems-based models of organizational safety. Such models represent a theoretical and practical development of the safety climate concept by positioning climate as part of a dynamic work system in which perceptions of safety act to constrain and shape employee behavior. We propose safety climate and safety culture constitute part of the enabling capitals through which organizations build safety capability. We discuss how organizations can deploy different configurations of enabling capital to exert control over work systems and maintain safe and productive performance. We outline 4 key strategies through which organizations to reconcile the system control problems of promotion versus prevention, and stability versus flexibility.

  8. Structural stigma: Research evidence and implications for psychological science.

    Science.gov (United States)

    Hatzenbuehler, Mark L

    2016-11-01

    Psychological research has provided essential insights into how stigma operates to disadvantage those who are targeted by it. At the same time, stigma research has been criticized for being too focused on the perceptions of stigmatized individuals and on microlevel interactions, rather than attending to structural forms of stigma. This article describes the relatively new field of research on structural stigma, which is defined as societal-level conditions, cultural norms, and institutional policies that constrain the opportunities, resources, and well-being of the stigmatized. I review emerging evidence that structural stigma related to mental illness and sexual orientation (a) exerts direct and synergistic effects on stigma processes that have long been the focus of psychological inquiry (e.g., concealment, rejection sensitivity), (b) serves as a contextual moderator of the efficacy of psychological interventions, and (c) contributes to numerous adverse health outcomes for members of stigmatized groups-ranging from dysregulated physiological stress responses to premature mortality-indicating that structural stigma represents an underrecognized mechanism producing health inequalities. Each of these pieces of evidence suggests that structural stigma is relevant to psychology and therefore deserves the attention of psychological scientists interested in understanding and ultimately reducing the negative effects of stigma.

  9. The unconscious pursuit of emotion regulation: Implications for psychological health

    Science.gov (United States)

    Hopp, Henrik; Troy, Allison S.; Mauss, Iris B.

    2012-01-01

    Because of the central involvement of emotion regulation in psychological health and the role that implicit (largely unconscious) processes appear to play in emotion regulation, implicit emotion-regulatory processes should play a vital role in psychological health. We hypothesised that implicitly valuing emotion regulation translates into better psychological health in individuals who use adaptive emotion-regulation strategies. A community sample of 222 individuals (56% women) who had recently experienced a stressful life event completed an implicit measure of emotion regulation valuing (ER-IAT) and reported on their habitual use of an important adaptive emotion-regulation strategy: cognitive reappraisal. We measured three domains of psychological health: well-being, depressive symptoms, and social adjustment. As hypothesised, individuals who implicitly valued emotion regulation exhibited greater levels of psychological health, but only when they were high in cognitive reappraisal use. These findings suggest that salutary effects of unconscious emotion-regulation processes depend on its interplay with conscious emotion-regulation processes. PMID:21432692

    2015-06-01

    Full Text Available The relationship between tourism and changing climate has been discussed and studied for a relatively long time in tourism research. Over the past 15 years, more focused studies have begun to appear, and especially recently, the issue of adaptation and mitigation has been emphasized as an urgent research need in tourism and climate change studies. This paper is based on the review of selected articles which discuss the several forms of tourism and climate change and provide recommendations for mitigation and adaptation measures. This review paper assesses the impacts of climate change on the popular forms of tourism such as; mountain tourism, wildlife tourism, adventure tourism, sun/sand tourism; last chance tourism, and describes the extent of tourism vulnerabilities and their implications. The paper concludes that the appropriate adaptation and mitigation measures have to be followed to minimize the risk of climate change while trying to save all forms of tourism. The initiative of this article is to present an overview of the existing literature on the relationship between tourism and climate change in order to establish the current state of corporate and institutional responses within the tourism industry and to set out an agenda for future research. The currency of the review is evident given the recent surge in popular discussion on climate change and its effects on tourism, and the appearance of a broad and disparate array of studies on this topic.

    2018-01-01

    When, if ever, should psychological scientists be permitted to offer professional opinions concerning the mental health of public figures they have never directly examined? This contentious question, which attracted widespread public attention during the 1964 U.S. presidential election involving Barry Goldwater, received renewed scrutiny during and after the 2016 U.S. presidential campaign, when many mental health professionals raised pointed questions concerning the psychiatric status of Donald Trump. Although the Goldwater Rule prohibits psychiatrists from offering diagnostic opinions on individuals they have never examined, no comparable rule exists for psychologists. We contend that, owing largely to the Goldwater Rule's origins in psychiatry, a substantial body of psychological research on assessment and clinical judgment, including work on the questionable validity of unstructured interviews, the psychology of cognitive biases, and the validity of informant reports and of L (lifetime) data, has been overlooked in discussions of its merits. We conclude that although the Goldwater Rule may have been defensible several decades ago, it is outdated and premised on dubious scientific assumptions. We further contend that there are select cases in which psychological scientists with suitable expertise may harbor a "duty to inform," allowing them to offer informed opinions concerning public figures' mental health with appropriate caveats.

    2015-03-01

    Poor diet, physical inactivity, tobacco smoking and alcohol consumption are major risk factors for chronic disease and premature mortality. These behaviours are of concern among higher education students and may be linked to psychological distress which is problematic particularly for students on programmes with practicum components such as nursing and teaching. Understanding how risk behaviours aggregate and relate to psychological distress and coping among this population is important for health promotion. This research examined, via a comprehensive survey undergraduate nursing/midwifery and teacher education students' (n = 1557) lifestyle behaviour (Lifestyle Behaviour Questionnaire), self-reported psychological distress (General Health Questionnaire) and coping processes (Ways of Coping Questionnaire). The results showed that health- risk behaviours were common, including alcohol consumption (93.2%), unhealthy diet (26.3%), physical inactivity (26%), tobacco smoking (17%), cannabis use (11.6%) and high levels of stress (41.9%). Students tended to cluster into two groups: those with risk behaviours (n = 733) and those with positive health behaviours (n = 379). The group with risk behaviours had high psychological distress and used mostly passive coping strategies such as escape avoidance. The potential impact on student health and academic achievement is of concern and suggests the need for comprehensive health promotion programmes to tackle multiple behaviours. As these students are the nurses and teachers of the future, their risk behaviours, elevated psychological distress and poor coping also raise concerns regarding their roles as future health educators/promoters. Attention to promotion of health and well-being among this population is essential. © The Author 2014. Published by Oxford University Press. All rights reserved.

    Visualization of climate data plays an integral role in the communication of climate change findings to both expert and non-expert audiences. The cognitive and psychological sciences can provide valuable insights into how to improve visualization of climate data based on knowledge of how the human brain processes visual and linguistic information. We review four key research areas to demonstrate their potential to make data more accessible to diverse audiences: directing visual attention, visual complexity, making inferences from visuals, and the mapping between visuals and language. We present evidence-informed guidelines to help climate scientists increase the accessibility of graphics to non-experts, and illustrate how the guidelines can work in practice in the context of Intergovernmental Panel on Climate Change graphics.

    Greenglass, E. R.

    1975-01-01

    Approximately 9 months after a legal therapeutic abortion, 188 Canadian women were interviewed. One half were single and the rest were married, separated or divorced. They were matched closely for a number of demographic variables with control women who had not had abortions. Neurotic disturbance in several areas of personality functioning was assessed from questionnaire responses. Out of 27 psychological scales, differences between the abortion and control groups were found on only 3: in general, women who had had abortions were more rebellious than control women, abortion tended to be associated with somewhat greater depression in married women, and single women who had had abortions scored higher on the shallow-affect scale. However, all the personality scores were well within the normal range. Perceived social support was strongly associated with favourable psychological reactions after abortion. Use of contraceptives improved greatly after the abortion, when over 90% of women reported using contraceptives regularly. PMID:803127

    2008-09-01

    In polycystic ovary syndrome (PCOS), one of the main features is chronic anovulation associated with lower pregnancy rates. Little is known regarding the psychological aspects associated with infertility in these patients. Therefore, we examined the influence of an unfulfilled wish to conceive on various aspects of psychological functioning in PCOS women. Standardized questionnaires assessing quality-of-life (36-item short-form health survey, SF-36), depressiveness (Beck Depression Inventory), emotional distress (Symptom Check List 90, SCL-90-R), sexual satisfaction and self-worth (visual analogue scales), and a questionnaire on the desire for a child (FKW) were administered at the outpatient endocrine clinic to consecutive PCOS patients. Questionnaires from 115 PCOS patients were analysed. The majority (76.1%) worried about remaining childless in the future, and 51.3% reported a current wish to conceive. 23.9% of patients had scores indicating mild to moderate depression, and 25.2% had scores indicating clinically relevant depression. Furthermore, all quality-of-life scores were significantly lower compared with normative data (P infertility. However for PCOS patients who wished to conceive, the wish for a child was a significantly greater priority when compared with normative data from infertile patients. PCOS represents a major risk factor for psychosocial and emotional problems, but at least in this sample of PCOS patients, infertility does not appear to constitute a primary determinant of psychological problems.

  12. Implications of climate change on flow regime affecting Atlantic salmon

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available The UKCIP02 climate change scenarios (2070–2100 suggest that the UK climate will become warmer (an overall increase of 2.5–3°C, with temperature increases being greater in the summer and autumn than in the spring and winter seasons. In terms of precipitation, winters are expected to become wetter and summers drier throughout the UK. The effect of changes in the future climate on flow regimes are investigated for the Atlantic salmon, Salmo salar, in a case study in an upland UK river. Using a hydraulic modelling approach, flows simulated across the catchment are assessed in terms of hydraulic characteristics (discharge per metre width, flow depths, flow velocities and Froude number. These, compared with suitable characteristics published in the literature for various life stages of Atlantic salmon, enable assessment of habitat suitability. Climate change factors have been applied to meteorological observations in the Eden catchment (north-west England and effects on the flow regime have been investigated using the SHETRAN hydrological modelling system. High flows are predicted to increase by up to 1.5%; yet, a greater impact is predicted from decreasing low flows (e.g. a Q95 at the outlet of the study catchment may decrease to a Q85 flow. Reliability, Resilience and Vulnerability (RRV analysis provides a statistical indication of the extent and effect of such changes on flows. Results show that future climate will decrease the percentage time the ideal minimum physical habitat requirements will be met. In the case of suitable flow depth for spawning activity at the outlet of the catchment, the percentage time may decrease from 100% under current conditions to 94% in the future. Such changes will have implications for the species under the Habitats Directive and for catchment ecological flow management strategies.

Sanchez and Loredo (Integrative Psychological & Behavioral Science 43:332-349, 2009) propose a classification of constructivist thinkers and address what they perceive to be internal problems of present-day constructivism. The remedy they propose is a return to the genetic constructivism of James Mark Baldwin, Jean Piaget and Lev Vygotsky. In this article we first raise the question of whether thinkers like Baldwin, Vygotsky, Maturana and Varela are adequately depicted as constructivists, and subsequently argue that constructivism is caught in an overly epistemic version of the subject/object dichotomy. We then introduce a genetic logic that is not based on the Hegelian dialectics of negation and mediation, but rather on the idea of the recursive consensual coordination of actions that give rise to stylized cultural practices. We argue that a genuinely genetic and generative psychology should be concerned with the multifarious and ever-changing nature of human 'life' and not merely with the construction of knowledge about life.

  18. Psychology and the Notion of the Spirit: Implications of Max Scheler's Anthropological Philosophy in Theory of Psychology.

    Lehmann, Olga V; Klempe, Sven Hroar

    2015-09-01

    After many decades with neglect Max Scheler and his anthropological contributions to the understanding of human existence, have gotten  more attention in psychology and other humanities. One factor is the actuality of his main project of revaluating the roles of values in philosophy and science. Yet another is the way individual scholars have applied Scheler's philosophy and terms on different fields and arenas. Viktor Frankl was one of these, and he brought Scheler's philosophical anthropology into psychotherapeutic practice, offering theoretical and empirical arguments for considering the notion of the spirit as an interdependent -yet separate- entity in regards to the psyche and the soma. During this commentary on Allyushin (Integrative Psychology Behaviour, 48, 503-523, 2014), we will discuss some general aspects of Scheler's contribution to phenomenology, but focus specifically on the implication of his notion of the spirit for psychological theory, acknowledging the work that has been done in the field for at least 60 years in logotherapy and existential analysis. With this purpose, we will highlight four other notions interrelated with the motivational quality of the notion of the spirit: resentment, axiology of values; self-detachment and self-transcendence.

  19. Climate Implications of the Heterogeneity of Anthropogenic Aerosol Forcing

    Science.gov (United States)

    Persad, Geeta Gayatri

    Short-lived anthropogenic aerosols are concentrated in regions of high human activity, where they interact with radiation and clouds, causing horizontally heterogeneous radiative forcing between polluted and unpolluted regions. Aerosols can absorb shortwave energy in the atmosphere, but deplete it at the surface, producing opposite radiative perturbations between the surface and atmosphere. This thesis investigates climate and policy implications of this horizontal and vertical heterogeneity of anthropogenic aerosol forcing, employing the Geophysical Fluid Dynamics Laboratory's AM2.1 and AM3 models, both at a global scale and using East Asia as a regional case study. The degree of difference between spatial patterns of climate change due to heterogeneous aerosol forcing versus homogeneous greenhouse gas forcing deeply impacts the detection, attribution, and prediction of regional climate change. This dissertation addresses a gap in current understanding of these two forcings' response pattern development, using AM2.1 historical forcing simulations. The results indicate that fast atmospheric and land-surface processes alone substantially homogenize the global pattern of surface energy flux response to heterogeneous aerosol forcing. Aerosols' vertical redistribution of energy significantly impacts regional climate, but is incompletely understood. It is newly identified here, via observations and historical and idealized forcing simulations, that increased aerosol-driven atmospheric absorption may explain half of East Asia's recent surface insolation decline. Further, aerosols' surface and atmospheric effects counteract each other regionally---atmospheric heating enhances summer monsoon circulation, while surface dimming suppresses it---but absorbing aerosols' combined effects reduce summer monsoon rainfall. This thesis constitutes the first vertical decomposition of aerosols' impacts in this high-emissions region and elucidates the monsoonal response to aerosols

  20. Globalization of psychology: Implications for the development of psychology in Ethiopia.

    Science.gov (United States)

    Swancott, Rachel; Uppal, Gobinderjit; Crossley, Jon

    2014-10-01

    The present article reports on the variation of mental health resources across the globe and considers the merits or otherwise of the process of globalization in low- and middle-income countries (LMIC), with a specific emphasis on Ethiopia. Although globalization has gained momentum in recent years, there is a concern that the globalization of Western mental health frameworks is problematic, as these concepts have been developed in a different context and do not accommodate the current diversity in understanding in LMIC countries. The importance of understanding the mental health frameworks of LMIC like Ethiopia, prior to considering if and how aspects of high-income countries (HIC) conceptualizations may be appropriately imported, is therefore reflected upon. Traditional approaches in managing mental health difficulties and possible reasons for the limited engagement with clinical psychology in Ethiopia are considered. Current developments within the fields of mental health and clinical psychology in Ethiopia are discussed, and the need to develop more local research in order to increase understanding and evaluate treatment interventions is recognized. Further consideration and debate by Ethiopian mental health professionals as well as those from HIC are recommended, to promote both reciprocal learning and new local discourses about mental health.

  1. Power and action in critical theory across disciplines: implications for critical community psychology.

    Although critical scholarship and community psychology share similar aspirations, the links between them remain unexplored and under-theorized. In this article we explore the implications of critical scholarship in various specialties for the field of community psychology. To understand the contributions of critical scholarship to a theory of power and action for social change, we conducted a systematic analysis of a ten-year period of publications in seven journals associated with the critical scholarship tradition. We created precise criteria for the concepts of power and action and applied them to the publications. Results indicate an interesting paradox at play. Whereas community psychology is more action oriented than critical scholarship, its actions fall short of challenging institutionalized power structures and the status quo; and whereas critical scholarship is more challenging of the status quo than community psychology in theory, it has failed to produce viable actions that challenge the status quo. We discuss the implications of this state of affairs for the development of a more critical community psychology.

    The goals of this study were twofold: (1) to confirm a relationship between employee perceptions of psychological safety climate and safety behavior for a sample of workers in the rail industry and (2) to explore the relative strengths of relationships between specific facets of safety climate and safety behavior. Non-management rail maintenance workers employed by a large North American railroad completed a survey (n=421) regarding workplace safety perceptions and behaviors. Three facets of safety climate (management safety, coworker safety, and work-safety tension) were assessed as relating to individual workers' reported safety behavior. All three facets were significantly associated with safety behavior. Dominance analysis was used to assess the relative importance of each facet as related to the outcome, and work-safety tension evidenced the strongest relationship with safety behavior.

  3. Implications of global warming for the climate of African rainforests.

    2013-01-01

    African rainforests are likely to be vulnerable to changes in temperature and precipitation, yet there has been relatively little research to suggest how the regional climate might respond to global warming. This study presents projections of temperature and precipitation indices of relevance to African rainforests, using global climate model experiments to identify local change as a function of global temperature increase. A multi-model ensemble and two perturbed physics ensembles are used, one with over 100 members. In the east of the Congo Basin, most models (92%) show a wet signal, whereas in west equatorial Africa, the majority (73%) project an increase in dry season water deficits. This drying is amplified as global temperature increases, and in over half of coupled models by greater than 3% per °C of global warming. Analysis of atmospheric dynamics in a subset of models suggests that this could be partly because of a rearrangement of zonal circulation, with enhanced convection in the Indian Ocean and anomalous subsidence over west equatorial Africa, the Atlantic Ocean and, in some seasons, the Amazon Basin. Further research to assess the plausibility of this and other mechanisms is important, given the potential implications of drying in these rainforest regions.

  4. The dragons of inaction: psychological barriers that limit climate change mitigation and adaptation.

    Gifford, Robert

    2011-01-01

    Most people think climate change and sustainability are important problems, but too few global citizens engaged in high-greenhouse-gas-emitting behavior are engaged in enough mitigating behavior to stem the increasing flow of greenhouse gases and other environmental problems. Why is that? Structural barriers such as a climate-averse infrastructure are part of the answer, but psychological barriers also impede behavioral choices that would facilitate mitigation, adaptation, and environmental sustainability. Although many individuals are engaged in some ameliorative action, most could do more, but they are hindered by seven categories of psychological barriers, or "dragons of inaction": limited cognition about the problem, ideological world views that tend to preclude pro-environmental attitudes and behavior, comparisons with key other people, sunk costs and behavioral momentum, discredence toward experts and authorities, perceived risks of change, and positive but inadequate behavior change. Structural barriers must be removed wherever possible, but this is unlikely to be sufficient. Psychologists must work with other scientists, technical experts, and policymakers to help citizens overcome these psychological barriers.

    Elder abuse and psychological distress are both important geriatric syndromes and are independently associated with premature morbidity and mortality. Despite recent advances, there has been little systematic exploration of the association between elder abuse and psychological distress. This systematic review synthesizes the qualitative and quantitative studies on the relationship between elder abuse and psychological distress, namely psychological distress as a risk factor and/or a consequence of elder abuse. Moreover, through this review, future research directions for elder abuse and psychological distress and their implications for practice and policy to improve the health and aging of vulnerable populations are also highlighted.

    Makeup acts and stimulates three of our senses: touch (which encompasses all sensations from the body surface), smell (fragrance), and sight (the process of becoming and looking beautiful). The positive stimulation of these senses by makeup can induce sensory as well as psychological pleasure. In order to understand the relationship of women to their makeup, we interviewed different groups of women on their quality of life and makeup habits. Then, through four standard well-validated psychometric self-questionnaires, we examined the possible relation between the need to make up oneself and specific psychological features. Our first results clearly showed that makeup could support two opposite "up" functions, i.e., "camouflage" vs "seduction." Concerning their psychological profiles, results showed that women of the functional class "camouflage" are more anxious, defensive, and emotionally unstable compared to those of the functional class "seduction," who appear to be more sociable, assertive, and extroverted. Further analyses revealed a division of the two classes into subclasses of volunteers with opposed personality and psychological profiles. This new classification allowed us to define more precisely the relations existing within the subjective experience of women during the makeup process. In conclusion, our study revealed that beyond the simple application of colorful products on the face, makeup has two major functional implications depending on specific psychological profiles of women.

    This study examined the religious and psychological implications of religious coping in Iran. University students (N = 224) responded to the Brief Positive and Negative Religious Coping Scales along with measures of Religious Orientation, Integrative Self-Knowledge, Self-Control, Mindfulness, Self-Compassion, Self-Esteem, Guilt, Shame, and Self-Criticism. As in previous research elsewhere, Positive Religious Coping was stronger on average than Negative Religious Coping, and Positive and Negative Religious Coping predicted adjustment and maladjustment, respectively, In addition, this study demonstrated that direct relationships between Positive and Negative Religious Coping appeared to be reliable in Iran; that Positive Religious Copings was broadly compatible with, and Negative Religious Coping was largely irrelevant to, Iranian religious motivations; and that Negative Religious Coping obscured linkages of Positive Religious Coping with religious and psychological adjustment.

  13. Implications of Climate Change for Ghana’s Economy

    Directory of Open Access Journals (Sweden)

    Channing Arndt

    2015-06-01

    Full Text Available Long-run economic development in Ghana is potentially vulnerable to anthropogenic climate change given the country’s dependence on rain-fed agriculture, hydropower and unpaved rural roads. We use a computable general equilibrium model, informed by detailed sector studies, to estimate the economy-wide impacts of climate change under four climate projections. Climate change is found to always reduce national welfare, with poor and urban households and the northern Savannah zone being the worst affected. However, there is wide variation across scenarios in the size of climate impacts and in the relative importance of sectoral impact channels, thus underscoring the need for multi-sector approaches that account for climate uncertainty. Our analysis of adaptation options indicates that investing in agricultural research and extension, and improved road surfaces, are potentially cost-effective means of mitigating most of the damages from climate change in Ghana.

    This article is about the neural correlates of infant mental health and their correspondences to social emotional development. These correspondences are organized in terms of the definition of infant mental provided by Zero to Three (2001), centered on infants' capacities regarding the experience and expression of emotions, interpersonal relationships, and learning. We conclude with implications of these correspondences for counseling psychology-namely, working with children's caregivers to maximize children's healthy social and emotional development.

    Vezhnovets T.A.

    2017-06-01

    Full Text Available The aim of the research was to identify the major factors that can positively or negatively effect the state of the socio-psychological climate in the medical team of healthcare institutions. The psychological study of the social-psychologic climate of 152 health care workers of two hospitals of Kherson region (N 1, n=80; N 2, n=72 was conducted. It is established that the level of self-esteem of climate in the institution №1 was significantly lower than in institution N 2 (р<0,007. Moreover, these two institutions differed significantly by experience of joint work of health workers (р<0.05 and length of service of the head physicians. Health care workers with less joint work experience have been working in the institution N 1, and it was headed by the head physician with less leading experience. By the opinion of health workers of both institutions, such factors as "interesting and meaningful work", "attentive head", "relations with colleagues", have the most positive impact on the state of climate the most negative influence — "unsatisfactory management style", "tensions in the team", "lack of financial motivation", "poor working conditions". Each team has its own combination of factors that positively or negatively affect the state of the climate. It is established, that depending on the work experience of the head physician and the work experience of joint work of employees, the main factors that affect the climate in the team are "attentive manager" and "relationships with colleagues". The more work experience of the leader, the more it will affect the state of the climate in the team. The less experience of joint work of employees, the more "relationship with colleagues" will affect its condition. Evaluation of the state of socio-psychological climate and its factors by the personnel may be the indicator of efficiency of personnel management in the health care institution.

    2008-11-01

    The most severe consequences of climate change will accrue to the poorest people in the poorest countries, despite their own negligible contribution to greenhouse gas emissions. In recent years, global health efforts in those same countries have grown dramatically. However, the emerging scientific consensus about climate change has not yet had much influence on the routine practice and strategies of global health. We review here the anticipated types and global distribution of health impacts of climate change, discuss relevant aspects of current global interventions for health in low-income countries, and consider potential elements of a framework for appropriately and efficiently mainstreaming global climate change-mitigation and -adaptation strategies into the ongoing enterprise of global health. We propose a collaborative learning initiative involving four areas: (1) increased awareness among current global health practitioners of climate change and its potential impacts for the most disadvantaged, (2) strengthening of the evidence base, (3) incorporation now of climate change-mitigation and -adaptation concerns into design of ongoing global health programs, and (4) alignment of current global health program targets and methods with larger frameworks for climate change and sustainable development. The great vulnerability to climate change of populations reached by current global health efforts should prompt all concerned with global health to take a leading role in advocating for climate change mitigation in their own countries.

    The aim of this study was to examine how students' perceptions of the class climate influence their basic psychological needs, motivational regulations, social goals and outcomes such as boredom, enjoyment, effort, and pressure/tension. 507 (267 males, 240 females) secondary education students agreed to participate. They completed a questionnaire that included the Spanish validated versions of Perceived Motivational Climate in Sport Questionnaire (PMCSQ-2), Basic Psychological Needs in Exercise (BPNES), Perceived Locus of Causality (PLOC), Social Goal Scale-Physical Education (SGS-PE), and several subscales of the IMI. A hierarchical cluster analysis uncovered four independent class climate profiles that were confirmed by a K-Means cluster analysis: "high ego", "low ego-task", "high ego-medium task", and "high task". Several MANOVAs were performed using these clusters as independent variables and the different outcomes as dependent variables (p class climates to positive consequences such as higher students' autonomy, competence, relatedness, intrinsic motivation, effort, enjoyment, responsibility and relationship, as well as low levels of amotivation, boredom and pressure/tension. Students' perceptions of a performance class climate made the positive scores decrease significantly. Cluster 3 revealed that a mastery oriented class structure undermines the negative behavioral and psychological effects of a performance class climate. This finding supports the buffering hypothesis of the achievement goal theory.

    Technology usage has seen an increase among users. The usage varies from social, personal, and psychological reasons. Users are frequently using to overcome mood states as well as to manage the other psychological states. This work is going to explore the information technology use among subjects with a psychiatric disorder. A total of 75 subjects were assessed using background data sheet, internet addiction impairment index, video game use pattern, pornography addiction screening tool and screening for mobile phone use, from in-patient and out-patient setting of tertiary mental health setting. It showed the presence of addiction to mobile, internet, video game, and pornography. Age was found to be negatively correlated with this addiction. Average usage time had been associated with management of mood states. The addiction to information technology had been associated with a delay in initiation of sleep. This work has implication for screening technology addiction among subjects seeking treatment for psychological problems and motivate them to develop the healthy use of technology.

    In this article, we define the construct of empathy and its relevance for counseling psychology. The importance of deficits in empathic processes for most of the psychological disorders is presented within the context of the social brain hypothesis (Frith, 2007). We provide a review of empirical research about the neural correlates of empathy in terms of both the central and peripheral nervous system. We present recent evidence on the cortical and subcortical regions involved in different dimensions of empathy-emotional contagion, cognitive and emotional empathy, and self-regulation. Regarding the autonomic correlates of empathy, we present evidence about the correlates of sympathetic arousal associated with empathic processes and review data supporting the idea of the physiological linkage or synchrony as indicator of empathy in interpersonal relationships. The implications of these findings for counseling psychology, particularly for the psychotherapist-client relationship and for context of intimate relationships or couples therapy, are discussed.

    This paper critically analyses the historical embeddedness and ideological functions of the concept of community as it is used in South Africa by representatives of the state and its opponents. The analysis shows that 'community' is a key concept in the ideology of separatism through which an apartheid psychology and society is reproduced. This has implications for progressive psychologists who aim to empower oppressed ordinary people through interventions based upon theoretical models of community. Some of these are explored by examining the interplay between political and theoretical images of community and ordinary people's ideas about social ills. This suggests that whilst community psychology can revitalise a sense of community amongst the oppressed, it may also reinforce existing social inequalities by deflecting experts and ordinary people from the reconstruction of individual agency upon which liberating social transformation depends. It is concluded that a central task for South African psychologists is to engage in critical self-reflection with the aim of identifying and eliminating oppressive forms of social and psychological discourse, thereby empowering themselves and contributing to the construction of a coherent counterideology.

  3. Implications of climate mitigation for future agricultural production

    Climate change is projected to negatively impact biophysical agricultural productivity in much of the world. Actions taken to reduce greenhouse gas emissions and mitigate future climate changes, are thus of central importance for agricultural production. Climate impacts are, however, not unidirectional; some crops in some regions (primarily higher latitudes) are projected to benefit, particularly if increased atmospheric carbon dioxide is assumed to strongly increase crop productivity at large spatial and temporal scales. Climate mitigation measures that are implemented by reducing atmospheric carbon dioxide concentrations lead to reductions both in the strength of climate change and in the benefits of carbon dioxide fertilization. Consequently, analysis of the effects of climate mitigation on agricultural productivity must address not only regions for which mitigation is likely to reduce or even reverse climate damages. There are also regions that are likely to see increased crop yields due to climate change, which may lose these added potentials under mitigation action. Comparing data from the most comprehensive archive of crop yield projections publicly available, we find that climate mitigation leads to overall benefits from avoided damages at the global scale and especially in many regions that are already at risk of food insecurity today. Ignoring controversial carbon dioxide fertilization effects on crop productivity, we find that for the median projection aggressive mitigation could eliminate ∼81% of the negative impacts of climate change on biophysical agricultural productivity globally by the end of the century. In this case, the benefits of mitigation typically extend well into temperate regions, but vary by crop and underlying climate model projections. Should large benefits to crop yields from carbon dioxide fertilization be realized, the effects of mitigation become much more mixed, though still positive globally and beneficial in many food insecure

    Agricultural land use plays an important role in land-atmosphere interaction. Agricultural activity is one of the most important processes driving human-induced land use land cover change (LULCC) in a region. In addition to future socioeconomic changes, climate-induced changes in crop yield represent another important factor shaping agricultural land use. In feedback, the resulting LULCC influences the direction and magnitude of global, regional and local climate change by altering Earth's radiative equilibrium. Therefore, assessment of climate change impact on future agricultural land use and its feedback is of great importance in climate change study. In this study, to evaluate the feedback of projected land use changes to the regional climate in West Africa, we employed an asynchronous coupling between a regional climate model (RegCM) and a prototype land use projection model (LandPro). The LandPro model, which was developed to project the future change in agricultural land use and the resulting shift in natural vegetation in West Africa, is a spatially explicit model that can account for both climate and socioeconomic changes in projecting future land use changes. In the asynchronously coupled modeling framework, LandPro was run for every five years during the period of 2005-2050 accounting for climate-induced change in crop yield and socioeconomic changes to project the land use pattern by the mid-21st century. Climate data at 0.5˚ was derived from RegCM to drive the crop model DSSAT for each of the five-year periods to simulate crop yields, which was then provided as input data to LandPro. Subsequently, the land use land cover map required to run RegCM was updated every five years using the outputs from the LandPro simulations. Results from the coupled model simulations improve the understanding of climate change impact on future land use and the resulting feedback to regional climate.

    Climate change is projected to negatively impact biophysical agricultural productivity in much of the world. Actions taken to reduce greenhouse gas emissions and mitigate future climate changes, are thus of central importance for agricultural production. Climate impacts are, however, not unidirectional; some crops in some regions (primarily higher latitudes) are projected to benefit, particularly if increased atmospheric carbon dioxide is assumed to strongly increase crop productivity at large spatial and temporal scales. Climate mitigation measures that are implemented by reducing atmospheric carbon dioxide concentrations lead to reductions both in the strength of climate change and in the benefits of carbon dioxide fertilization. Consequently, analysis of the effects of climate mitigation on agricultural productivity must address not only regions for which mitigation is likely to reduce or even reverse climate damages. There are also regions that are likely to see increased crop yields due to climate change, which may lose these added potentials under mitigation action. Comparing data from the most comprehensive archive of crop yield projections publicly available, we find that climate mitigation leads to overall benefits from avoided damages at the global scale and especially in many regions that are already at risk of food insecurity today. Ignoring controversial carbon dioxide fertilization effects on crop productivity, we find that for the median projection aggressive mitigation could eliminate approximately 81% of the negative impacts of climate change on biophysical agricultural productivity globally by the end of the century. In this case, the benefits of mitigation typically extend well into temperate regions, but vary by crop and underlying climate model projections. Should large benefits to crop yields from carbon dioxide fertilization be realized, the effects of mitigation become much more mixed, though still positive globally and beneficial in many

    2014-06-01

    No research has empirically explored the non-academic concept of psychology itself (implicit theories) in non-Western cultures despite a widely held belief that this understanding differs cross-culturally. This study examined whether the non-academic concept of psychology among inexperienced Japanese students differed from the concept held by students of other countries. In Japanese, psychology is referred to as , which includes the ideographic character , literally meaning heart. This fact led us to hypothesize that psychology will be disproportionately associated with emotion among Japanese students. Indeed, our findings among Japanese students produced a J-curve, indicating that our prediction was true. We posit that this issue has never been discussed in Japan because a majority of people share this concept of psychology. In our second study, we examined not only preference in students' association of intelligence or emotion but also heart or mind with psychology. Finally, we identified whether students' believe that psychology encompasses both the heart and the mind. We conclude with a discussion of the importance of explicitly defining the non-academic concept of psychology in early psychology education in Japan. © 2013 International Union of Psychological Science.

    Greenhouse gases are driving climate change. This article explores the adverse health effects of climate change on a particularly vulnerable population: children and adults with respiratory conditions. This review provides a general overview of the effects of increasing temperatures, extreme weather, desertification, and flooding on asthma, chronic obstructive lung disease, and respiratory infections. We offer suggestions for future research to better understand climate change hazards, policies to support prevention and mitigation efforts targeting climate change, and clinical actions to reduce individual risk. Climate change produces a number of changes to the natural and built environments that may potentially increase respiratory disease prevalence, morbidity, and mortality. Nurses might consider focusing their research efforts on reducing the effects of greenhouse gases and in directing policy to mitigate the harmful effects of climate change. Nurses can also continue to direct educational and clinical actions to reduce risks for all populations, but most importantly, for our most vulnerable groups. While advancements have been made in understanding the impact of climate change on respiratory health, nurses can play an important role in reducing the deleterious effects of climate change. This will require a multipronged approach of research, policy, and clinical action. © 2017 Sigma Theta Tau International.

    Evaluating the trade-offs between the risks related to climate change, climate change mitigation as well as co-benefits requires an integrated scenarios approach to sustainable development. We outline a conceptual multi-objective framework to assess climate policies that takes into account climate impacts, mitigation costs, water and food availability, technological risks of nuclear energy and carbon capture and sequestration as well as co-benefits of reducing local air pollution and increasing energy security. This framework is then employed as an example to different climate change mitigation scenarios generated with integrated assessment models. Even though some scenarios encompass considerable challenges for sustainability, no scenario performs better or worse than others in all dimensions, pointing to trade-offs between different dimensions of sustainable development. For this reason, we argue that these trade-offs need to be evaluated in a process of public deliberation that includes all relevant social actors.

    We review the literature on organizational climate and culture paying specific attention to articles published in the Journal of Applied Psychology (JAP) since its first volume in 1917. The article traces the history of the 2 constructs though JAP has been far more important for climate than culture research. We distinguish 4 main periods: the pre-1971 era, with pioneering work on exploring conceptualization and operationalizations of the climate construct; the 1971-1985 era, with foundational work on aggregation issues, outcome-focused climates (on safety and service) and early writings on culture; the 1986-1999 era, characterized by solidification of a focused climate approach to understanding organizational processes (justice, discrimination) and outcomes (safety, service) and the beginnings of survey approaches to culture; and the 2000-2014 era, characterized by multilevel work on climate, climate strength, demonstrated validity for a climate approach to outcomes and processes, and the relationship between leadership and climate and culture. We summarize and comment on the major theory and research achievements in each period, showing trends observed in the literature and how JAP has contributed greatly to moving research on these constructs, especially climate, forward. We also recommend directions for future research given the current state of knowledge. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

  17. Assessing institutional capacities to adapt to climate change - integrating psychological dimensions in the Adaptive Capacity Wheel

    2013-03-01

    Several case studies show that "soft social factors" (e.g. institutions, perceptions, social capital) strongly affect social capacities to adapt to climate change. Many soft social factors can probably be changed faster than "hard social factors" (e.g. economic and technological development) and are therefore particularly important for building social capacities. However, there are almost no methodologies for the systematic assessment of soft social factors. Gupta et al. (2010) have developed the Adaptive Capacity Wheel (ACW) for assessing the adaptive capacity of institutions. The ACW differentiates 22 criteria to assess six dimensions: variety, learning capacity, room for autonomous change, leadership, availability of resources, fair governance. To include important psychological factors we extended the ACW by two dimensions: "adaptation motivation" refers to actors' motivation to realise, support and/or promote adaptation to climate. "Adaptation belief" refers to actors' perceptions of realisability and effectiveness of adaptation measures. We applied the extended ACW to assess adaptive capacities of four sectors - water management, flood/coastal protection, civil protection and regional planning - in North Western Germany. The assessments of adaptation motivation and belief provided a clear added value. The results also revealed some methodological problems in applying the ACW (e.g. overlap of dimensions), for which we propose methodological solutions.

    Several case studies show that social factors like institutions, perceptions and social capital strongly affect social capacities to adapt to climate change. Together with economic and technological development they are important for building social capacities. However, there are almost no methodologies for the systematic assessment of social factors. After reviewing existing methodologies we identify the Adaptive Capacity Wheel (ACW) by Gupta et al. (2010), developed for assessing the adaptive capacity of institutions, as the most comprehensive and operationalised framework to assess social factors. The ACW differentiates 22 criteria to assess 6 dimensions: variety, learning capacity, room for autonomous change, leadership, availability of resources, fair governance. To include important psychological factors we extended the ACW by two dimensions: "adaptation motivation" refers to actors' motivation to realise, support and/or promote adaptation to climate; "adaptation belief" refers to actors' perceptions of realisability and effectiveness of adaptation measures. We applied the extended ACW to assess adaptive capacities of four sectors - water management, flood/coastal protection, civil protection and regional planning - in northwestern Germany. The assessments of adaptation motivation and belief provided a clear added value. The results also revealed some methodological problems in applying the ACW (e.g. overlap of dimensions), for which we propose methodological solutions.

    Temperature-sensitive pathogenic species and their vectors and hosts are emerging in previously colder regions as a consequence of several factors, including global warming. As a result, an increasing number of people will be exposed to pathogens against which they have not previously needed defences. We illustrate this with a specific example of recent emergence of Cryptococcus gattii infections in more temperate climates. The outbreaks in more temperate climates of the highly virulent--but usually tropically restricted--C. gattii is illustrative of an anticipated growing challenge for the healthcare system. There is a need for preparedness by healthcare professionals in anticipation and for management of such outbreaks, including other infections whose recent increased prevalence in temperate climates can be at least partly associated with global warming. (Re)emergence of temperature-sensitive pathogenic species in more temperate climates will present new challenges for healthcare systems. Preparation for outbreaks should precede their occurrence. © 2012 Blackwell Publishing Ltd.

  4. Possible implications of global climate change on global lightning distributions and frequencies

    1994-01-01

    The Goddard Institute for Space Studies (GISS) general circulation model (GCM) is used to study the possible implications of past and future climate change on global lightning frequencies. Two climate change experiments were conducted: one for a 2 x CO2 climate (representing a 4.2 degs C global warming) and one for a 2% decrease in the solar constant (representing a 5.9 degs C global cooling). The results suggest at 30% increase in global lightning activity for the warmer climate and a 24% decrease in global lightning activity for the colder climate. This implies an approximate 5-6% change in global lightning frequencies for every 1 degs C global warming/cooling. Both intracloud and cloud-to-ground frequencies are modeled, with cloud-to-ground lightning frequencies showing larger sensitivity to climate change than intracloud frequencies. The magnitude of the modeled lightning changes depends on season, location, and even time of day.

    We investigate simulations conducted for the ongoing Climate Change Assessments in California. In this presentation, we explore implications of global climate change threshold targets on temperature, precipitation, sea level rise, snow pack, and extreme events including heat waves, wildfire and coastal flooding in California. A set of regional models driven by an ensemble of global climate change futures from 4th and 5th IPCC Assessment GCMs indicate how California's climate and thus its hydrological systems, coast and wildlands respond to increasing atmospheric greenhouse gas concentrations at levels that produce global warming of 1.5°C and beyond. Differing global greenhouse gas emissions scenarios would produce strongly diverging results after mid-21st Century, as emphasized by the suite of modeled regional climate measures. The results demonstrate that global emissions can be used, independent of emissions pathway (but not entirely and not for all climate and impact measures), to estimate physical changes at the local and regional levels in the State. These relationships are explored to re-interpret prior studies that were based on the SRES emission scenarios along with the current suite of RCP scenarios. In addition, because historical emissions are above what was envisioned for the RCPs, and since the 2015 Conference of Parties implies a departure from the RCPs, consideration of cumulative CO2 emissions provides a useful tool for contextualizing historical emissions and expected outcomes from COP21. Climate policy implications are described, including climate adaptation guidance that California entities are required or encouraged to follow.

    The Environmental Research Letters focus issue on ‘Cumulative Emissions, Global Carbon Budgets and the Implications for Climate Mitigation Targets’ was launched in 2015 to highlight the emerging science of the climate response to cumulative emissions, and how this can inform efforts to decrease emissions fast enough to avoid dangerous climate impacts. The 22 research articles published represent a fantastic snapshot of the state-or-the-art in this field, covering both the science and policy aspects of cumulative emissions and carbon budget research. In this Review and Synthesis, we summarize the findings published in this focus issue, outline some suggestions for ongoing research needs, and present our assessment of the implications of this research for ongoing efforts to meet the goals of the Paris climate agreement.

    Older adults often seek to manage their social networks to foster positive interactions, but they nonetheless sometimes experience negative interactions that detract from their health and well-being. Negative interactions may occur with ambivalent social partners (i.e., partners involved in both positive and negative exchanges) or exclusively problematic social partners (i.e., partners involved negative exchanges only), but conflicting views exist in the literature regarding which type of social partner is likely to be more detrimental to older adults’ physical and emotional health. This study examined the implications of the two kinds of network members for physical and psychological health and interpersonal coping responses in a representative sample of 916 older adults. Within this elderly sample, older age was associated with fewer ambivalent kin ties and fewer exclusively problematic kin ties. Analyses revealed that ambivalent social ties were more strongly related to functional health limitations than were exclusively problematic social ties, whereas problematic ties were more consistently related to psychological health than were ambivalent ties. Furthermore, negative exchanges that occurred with exclusively problematic social ties, as compared to those that occurred with ambivalent social ties, were associated with more avoidant and fewer conciliatory coping responses, stronger and longer-lasting negative emotions, and lower perceived coping effectiveness. A comprehensive understanding of the significance of social network ties in older adults’ lives may benefit not only from attention to sources of social support but also from efforts to distinguish between different sources of conflict and disappointment.

    Full Text Available The case of a 45-year-old woman who was admitted to our university hospital for polymenorrhea, weight gain and pain in the left iliac region is reported. An abdominal ultrasound revealed a 9.5 × 5.2-cm, hypoechoic and inhomogeneous mass located on the left side of the pelvis and behind the ovary. The patient underwent surgery. The pelvic mass was firmly anchored to the small intestine, colon, sigma and uterine fundus. After removing the adhesions, double ureters, which had been incorporated in the mass, were observed on the left side. Resection of the unilateral double ureters was necessary in order to remove the entire mass, and thereafter, a left salpingoophorectomy was performed. A histological examination showed a malignant retroperitoneal mass. Termino-terminal ureteral anastomosis with two double-J stents was carried out. Total hysterectomy with preservation of the right adenexum and regional lymphadenectomy was performed. The purpose of this case report is to discuss the physical and psychological implications related to the combination of two rare entities: leiomyosarcoma and a double ureter located within the mass. A literature review on the clinical management and psychological aspects from a female cancer patient's perspective undergoing surgery with the aforementioned disorders will be discussed.

    Background In recent years, investigators have focused increased attention on positive psychology constructs and their associations with health outcomes, such as morbidity, mortality, and adaptation to illness. The database regarding some of these concepts and models has grown appreciably, but work in this area has been subject to controversy. Purpose This special series of papers offers contrasting perspectives regarding research on positive psychology and health. Both proponents and critics were invited to review recent developments concerning a number of positive constructs that have been evaluated in the oncology literature and in health research, more generally. Methods Papers are presented in the format of a debate. Significant advances are reviewed by one set of investigators, Drs, Lisa G. Aspinwall and Richard G. Tedeschi, while shortcomings and concerns are highlighted by another set of investigators, Drs. James C. Coyne and Howard Tennen. Each of these review papers is followed by a rebuttal by the opposing side. A commentary on the exchange is provided by Dr. Sherri Sheinfeld Gorin. Results These papers address a range of important considerations regarding conceptualization of constructs, methodological rigor, dissemination of findings, and implications for practice. Conclusion The critiques and recommendations offered in these papers may help inform future efforts in this area, as the field continues to evolve. PMID:20306165

    2017-11-01

    This paper proposes a modeling framework able to analyze the alterations in watershed hydrology induced by two recurrent drivers for hydrological changes: climate change and urbanization. The procedure is based on the coupling of a stochastic weather generator with a land use change model for the generation of some hypothetical scenarios. The generated scenarios are successively used to force a physically-based and spatial distributed hydrological model to reconstruct the basin response under different conditions. Several potential climate alterations are simulated by imposing negative and positive variations in the mean annual precipitation and a simultaneous temperature increase. Urbanization is conceptualized by an increase in the impervious fraction of the basin. The procedure is applied to a large basin and a much smaller sub-basin; the results show how climate and land use changes may interact and affect the fundamental hydrological dynamics and how the processes governing basin hydrological response may change with spatial scale.

  12. A Common Methodology for Risk Assessment and Mapping of Climate Change Related Hazards—Implications for Climate Change Adaptation Policies

    Directory of Open Access Journals (Sweden)

    Maria Papathoma-Köhle

    2016-02-01

    Full Text Available The Intergovernmental Panel on Climate Change (IPCC, 2014, suggests that an important increase in frequency and magnitude of hazardous processes related to climate change is to be expected at the global scale. Consequently, it is necessary to improve the level of preparedness and the level of public awareness, to fill institutional gaps, and to improve territorial planning in order to reduce the potentially disastrous impact of natural hazards related to climate change. This paper mainly presents a new framework for risk assessment and mapping which enables countries with limited data sources to assess their risk to climate change related hazards at the local level, in order to reduce potential costs, to develop risk reduction strategies, to harmonize their preparedness efforts with neighboring countries and to deal with trans-boundary risk. The methodology is based on the European Commission’s “Risk Assessment and Mapping Guidelines for Disaster Management” (2010 and considers local restrictions, such as a lack of documentation of historic disastrous events, spatial and other relevant data, offering alternative options for risk assessment, and the production of risk maps. The methodology is based on event tree analysis. It was developed within the European project SEERISK and adapted for a number of climate change-related hazards including floods, heat waves, wildfires, and storms. Additionally, the framework offers the possibility for risk assessment under different future scenarios. The implications for climate change adaptation policy are discussed.

    2010-04-29

    Climate change is already affecting the distributions of many species and may lead to numerous extinctions over the next century. Small-range species are likely to be a special concern, but the extent to which they are sensitive to climate is currently unclear. Species distribution modeling, if carefully implemented, can be used to assess climate sensitivity and potential climate change impacts, even for rare and cryptic species. We used species distribution modeling to assess the climate sensitivity, climate change risks and conservation implications for a threatened small-range mammal species, the Iberian desman (Galemys pyrenaicus), which is a phylogenetically isolated insectivore endemic to south-western Europe.

    Full Text Available BACKGROUND: Climate change is already affecting the distributions of many species and may lead to numerous extinctions over the next century. Small-range species are likely to be a special concern, but the extent to which they are sensitive to climate is currently unclear. Species distribution modeling, if carefully implemented, can be used to assess climate sensitivity and potential climate change impacts, even for rare and cryptic species. METHODOLOGY/PRINCIPAL FINDINGS: We used species distribution modeling to assess the climate sensitivity, climate change risks and conservation implications for a threatened small-range mammal species, the Iberian desman (Galemys pyrenaicus, which is a phylogenetically isolated insectivore endemic to south-western Europe. Atlas data on the distribution of G. pyrenaicus was linked to data on climate, topography and human impact using two species distribution modeling algorithms to test hypotheses on the factors that determine the range for this species. Predictive models were developed and projected onto climate scenarios for 2070-2099 to assess climate change risks and conservation possibilities. Mean summer temperature and water balance appeared to be the main factors influencing the distribution of G. pyrenaicus. Climate change was predicted to result in significant reductions of the species' range. However, the severity of these reductions was highly dependent on which predictor was the most important limiting factor. Notably, if mean summer temperature is the main range determinant, G. pyrenaicus is at risk of near total extinction in Spain under the most severe climate change scenario. The range projections for Europe indicate that assisted migration may be a possible long-term conservation strategy for G. pyrenaicus in the face of global warming. CONCLUSIONS/SIGNIFICANCE: Climate change clearly poses a severe threat to this illustrative endemic species. Our findings confirm that endemic species can be

    2015-06-01

    The purpose of this investigation was to examine whether the relationships between contextual factors and basic psychological needs were related to antisocial and prosocial behavior in sport. A two-study project employing Bayesian path analysis was conducted with competitive athletes (Study 1, n = 291; Study 2, n = 272). Coach and teammate autonomy-supportive climates had meaningful direct relations with need satisfaction and prosocial behavior. Coach and teammate controlling climates had meaningful direct relations with antisocial behavior. Need satisfaction was both directly and indirectly related with both prosocial and antisocial behavior, whereas moral disengagement was directly and indirectly related with antisocial behavior. Overall, these findings reflected substantial evidence from the literature on self-determination theory that autonomy-supportive motivational climates are important environmental influences for need satisfaction, and are important correlates of prosocial behavior in sport, whereas controlling coach and teammate climates, along with moral disengagement, were important correlates of antisocial behavior in sport.

  7. The Growth of Developmental Thought: Implications for a New Evolutionary Psychology

    Science.gov (United States)

    Lickliter, Robert

    2009-01-01

    Evolution has come to be increasingly discussed in terms of changes in developmental processes rather than simply in terms of changes in gene frequencies. This shift is based in large part on the recognition that since all phenotypic traits arise during ontogeny as products of individual development, a primary basis for evolutionary change must be variations in the patterns and processes of development. Further, the products of development are epigenetic, not just genetic, and this is the case even when considering the evolutionary process. These insights have led investigators to reconsider the established notion of genes as the primary cause of development, opening the door to research programs focused on identifying how genetic and non-genetic factors coact to guide and constrain the process of development and its outcomes. I explore this growth of developmental thought and its implications for the achievement of a unified theory of heredity, development, and evolution and consider its implications for the realization of a new, developmentally-based evolutionary psychology.

    . The core misconception espoused pertains to the view that major depression is not a medical illness; a finding which can also be interpreted in light of the lingering controversy on the medicalization of normal sadness and human predicament. The clinical implications of these findings are substantial. Mental health professionals-educators should reflect on their own beliefs and attitudes towards depression, as they may convey stigmatizing messages to their students and thus perpetuate the stigmatization of the illness. Concomitantly, psychology students' attitudes to depression and its treatment might render them incapable of understanding their patients, responding to their needs and providing them with appropriate help, while they may hinder their effective collaboration with psychiatrists.

    2016-04-01

    Full Text Available Orientation: A large body of research evidence indicates that both sex role identity (SRI and psychological capital (PsyCap may have critical implications for individual and organisational well-being. As SRI is constituted of sex-based personality traits it is possible that SRI may have implications for individuals’ PsyCap.Research purpose: The purpose of this study was to investigate the relationship between SRI and the positive psychological construct of PsyCap.Motivation for the study: Research on SRI and PsyCap has been explored independently of one another with a lack of research exploring the relationship between these two constructs. In addition, much of the previous research on SRI and organisational outcomes has only examined positive sex role identities, focusing almost exclusively on ‘positive’ or ‘socially desirable’ sex role identities. More recently, researchers have noted that this approach is theoretically and methodologically flawed, as it fails to account for negative traits or socially undesirable traits that may be contained within individuals’ SRI and which may have a number of deleterious implications for organisational outcome variables. Furthermore, there is a paucity of research within the South African context, which explores the adoption of positive and negative sexbased behavioural traits and their implications for PsyCap.Research design, approach and method: A quantitative study was conducted using a crosssectional design and a convenience sampling method to explore the relationship between SRI and PsyCap. Four hundred and seventy-eight respondents, all currently working in South African organisations, participated in this research. The composite questionnaire utilised for this research included a demographic questionnaire, The Extended Personal Attribute Questionnaire-Revised (EPAQ-R, and the PCQ-24 which measures PsyCap in terms of self-efficacy, hope, resilience and optimism.Main findings

    2011-04-19

    Projections of temperature and precipitation patterns across the United States during the next 50 years anticipate a 1.5 to 2°C warming and a slight increase in precipitation as a result of global climate change. There have been relatively few studies of climate change impacts on pasture and rangeland (grazingland) species compared to those on crop species, despite the economic and ecological importance of the former. Here we review the literature on pastureland and rangeland species to rising CO2 and climate change (temperature, and precipitation) and discuss plant and management factors likely to influence pastureland and rangeland responses to change (e.g., community composition, plant competition, perennial growth habit, seasonal productivity, and management methods). Overall, the response of pasture species to increased [CO2] is consistent with the general response of C3 and C4 type vegetation, although significant exceptions exist. Both pastureland and rangeland species should exhibit an acceleration of metabolism and development due to earlier onset of spring green-up and longer growing seasons. However, in the studies reviewed here, C3 pasture species increased their photosynthetic rates by up to 40% while C4 species exhibited no increase in photosynthesis. In general, it is expected that increases in [CO2] and precipitation would enhance rangeland net primary production (NPP) while increased air temperatures would either increase or decrease NPP. Much of this uncertainty in response is due to uncertain future projections of precipitation, both globally and regionally. For example, if annual precipitation changes little or declines, rangeland plant response to warming temperatures and rising [CO2] may be neutral or may decline due to increased water stress. This review reveals the need for comprehensive studies of climate change impacts on the pasture ecosystem including grazing regimes, mutualistic relationships (e.g., plant roots-nematodes; N

  13. The Safe Yield and Climatic Variability: Implications for Groundwater Management.

    2017-05-01

    Methods for calculating the safe yield are evaluated in this paper using a high-quality and long historical data set of groundwater recharge, discharge, extraction, and precipitation in a karst aquifer. Consideration is given to the role that climatic variability has on the determination of a climatically representative period with which to evaluate the safe yield. The methods employed to estimate the safe yield are consistent with its definition as a long-term average extraction rate that avoids adverse impacts on groundwater. The safe yield is a useful baseline for groundwater planning; yet, it is herein shown that it is not an operational rule that works well under all climatic conditions. This paper shows that due to the nature of dynamic groundwater processes it may be most appropriate to use an adaptive groundwater management strategy that links groundwater extraction rates to groundwater discharge rates, thus achieving a safe yield that represents an estimated long-term sustainable yield. An example of the calculation of the safe yield of the Edwards Aquifer (Texas) demonstrates that it is about one-half of the average annual recharge. © 2016, National Ground Water Association.

  14. Export and Metabolism of Carbon in Urban Watersheds: Climate Implications

    Rivers export and transform globally-significant quantities of carbon from watersheds to coastal ecosystems. Urbanization and climate change influence these fluxes by altering the hydrologic regime, water temperature, and anthropogenic sources of organic matter. Here, we quantify export and metabolism of carbon in highly urbanized, coastal watersheds, and evaluate the importance of physical drivers linked to climate and land use. Using a combination of discrete-samples, continuous water quality sensors, lab experiments, and modeling, we quantified rates of DOC, DIC, and CO2 export as well as changes in DOC quality and in-stream metabolism in four highly developed watersheds of the Chesapeake Bay over three years. Annual DOC and DIC exports from the four watersheds varied from 9 to 23 and 19 to 59 Kg ha-1yr-1 respectively. The range of daily CO2 concentrations was 0.01 to 2.6mg L-1, equivalent to between 0.37 and 53% of daily DOC export across all streams and dates. All sites were net-heterotrophic for the majority of the year (NEP0) during spring and early summer. There was a significant (Purban watersheds can export significant amounts of DOC, DIC, and CO2 to coastal zones. The influence of urbanization on coastal water quality and greenhouse gases may be exacerbated by climate change as temperatures and storm frequency continue to rise.

    Global mean surface temperatures are rising in response to anthropogenic greenhouse gas emissions. The magnitude of this warming at equilibrium for a given radiative forcing—referred to as specific equilibrium climate sensitivity (S)—is still subject to uncertainties. We estimate global mean temperature variations and S using a 784,000-year-long field reconstruction of sea surface temperatures and a transient paleoclimate model simulation. Our results reveal that S is strongly dependent on the climate background state, with significantly larger values attained during warm phases. Using the Representative Concentration Pathway 8.5 for future greenhouse radiative forcing, we find that the range of paleo-based estimates of Earth’s future warming by 2100 CE overlaps with the upper range of climate simulations conducted as part of the Coupled Model Intercomparison Project Phase 5 (CMIP5). Furthermore, we find that within the 21st century, global mean temperatures will very likely exceed maximum levels reconstructed for the last 784,000 years. On the basis of temperature data from eight glacial cycles, our results provide an independent validation of the magnitude of current CMIP5 warming projections. PMID:28861462

    Full Text Available Introduction: The lack of mental health interferes with one's individual achievement and ability for undertaking the responsibilities of everyday life. Researches show that psychological well-being and parenting styles have an important role in ones' increasing general health. The current study examined the relationship between psychological well-being and parenting styles with students' mental health. Methods: This study was carried out on 278 students (124 boys and 154 girls of Boukan's high schools. The participants were asked to complete psychological well-being inventory and mental health parenting style questionnaire. Data was analyzed using of Pearson correlation coefficient and regression analysis. Results: The results showed that psychological well-being and authoritative parenting styles were significantly related with mental health; also, Permissive parenting styles has significant positive relationship with mental health. The regression analysis indicated that mental health is predictable by psychological well-being and parenting styles. Conclusion: The knowledge of parenting styles and psychological well-being and their relationships with general well-being can provide the significant implications on the provision of students' health. Parenting styles and psychological well-being, as significant variables in general well-being, needs more clinical research.

    2013-01-01

    The ocean is one of the principal reservoirs of CO2, a greenhouse gas, and therefore plays a crucial role in regulating Earth's climate. Currently, the ocean sequesters about a third of anthropogenic CO2 emissions, mitigating the human impact on climate. At the same time, the deeper ocean represents the largest carbon pool in the Earth System and processes that describe the transfer of carbon from the surface of the ocean to depth are intimately linked to the effectiveness of carbon sequestration.The ocean biological pump (OBP), which involves several biogeochemical processes, is a major pathway for transfer of carbon from the surface mixed layer into the ocean interior. About 75 of the carbon vertical gradient is due to the carbon pump with only 25 attributed to the solubility pump. However, the relative importance and role of the two pumps is poorly constrained. OBP is further divided to the organic carbon pump (soft tissue pump) and the carbonate pump, with the former exporting about 10 times more carbon than the latter through processes like remineralization.Major uncertainties about OBP, and hence in the carbon uptake and sequestration, stem from uncertainties in processes involved in OBP such as particulate organicinorganic carbon sinkingsettling, remineralization, microbial degradation of DOC and uptakegrowth rate changes of the ocean biology. The deep ocean is a major sink of atmospheric CO2 in scales of hundreds to thousands of years, but how the export efficiency (i.e. the fraction of total carbon fixation at the surface that is transported at depth) is affected by climate change remains largely undetermined. These processes affect the ocean chemistry (alkalinity, pH, DIC, particulate and dissolved organic carbon) as well as the ecology (biodiversity, functional groups and their interactions) in the ocean. It is important to have a rigorous, quantitative understanding of the uncertainties involved in the observational measurements, the models and the

    Despite research documenting variability in the sexual identity development of lesbian, gay, and bisexual (LGB) youths, it remains unclear whether different developmental patterns have implications for the psychological adjustment of LGB youths. The current report longitudinally examines whether different patterns of LGB identity formation and integration are associated with indicators of psychological adjustment among an ethnically diverse sample of 156 LGB youths (ages 14 – 21) in New York City. Although differences in the timing of identity formation were not associated with psychological adjustment, greater identity integration was related to less depressive and anxious symptoms, fewer conduct problems, and higher self-esteem both cross-sectionally and longitudinally. Individual changes in identity integration over time were associated with all four aspects of psychological adjustment, even after controlling for rival hypotheses concerning family and friend support, gay-related stress, negative social relationships, and other covariates. These findings suggest that difficulties in developing an integrated LGB identity may have negative implications for the psychological adjustment of LGB youths and that efforts to reduce distress among LGB youths should address the youths’ identity integration.

    2009-07-01

    The physical environment of the Canadian North is particularly sensitive to changes in climate because of a large concentration of cryospheric elements including both seasonal and multiyear forms of freshwater and sea ice, permafrost, snow, glaciers, and small ice caps. Because the cryosphere responds directly to changes in air temperature and precipitation, it is a primary indicator of the effects of climate variability and change. This article reviews the major changes that have occurred in the recent historical record of these cryospheric components at high latitudes in Canada. Some changes have been less pronounced in the Canadian North than elsewhere, such as changes in sea-ice coverage, whereas others have been potentially more significant, such as ablation of the extensive alpine and high-Arctic small glaciers and ice caps. Projections of future changes are also reviewed for each cryospheric component. Discussion about two other physical components of the North intrinsically linked to the cryosphere is also included, specifically: i) freshwater discharge to the Arctic Ocean via major river networks that are fed primarily by various forms of snow and ice, and ii) the related rise in sea level, which is strongly influenced by ablation of the cryosphere, and coastal stability, which also depends on the thermal integrity of coastal permafrost.

    Psychosocial safety climate (PSC) is defined as shared perceptions of organizational policies, practices and procedures for the protection of worker psychological health and safety, that stem largely from management practices. PSC theory extends the Job Demands-Resources (JD-R) framework and proposes that organizational level PSC determines work conditions and subsequently, psychological health problems and work engagement. Our sample was derived from the Australian Workplace Barometer project and comprised 30 organizations, and 220 employees. As expected, hierarchical linear modeling showed that organizational PSC was negatively associated with workplace bullying and harassment (demands) and in turn psychological health problems (health impairment path). PSC was also positively associated with work rewards (resources) and in turn work engagement (motivational path). Accordingly, we found that PSC triggered both the health impairment and motivational pathways, thus justifying extending the JD-R model in a multilevel way. Further we found that PSC, as an organization-based resource, moderated the positive relationship between bullying/harassment and psychological health problems, and the negative relationship between bullying/harassment and engagement. The findings provide evidence for a multilevel model of PSC as a lead indicator of workplace psychosocial hazards (high demands, low resources), psychological health and employee engagement, and as a potential moderator of psychosocial hazard effects. PSC is therefore an efficient target for primary and secondary intervention. Copyright © 2011 Elsevier Ltd. All rights reserved.

  3. Climate Mitigation Policy Implications for Global Irrigation Water Demand

    Energy, water and land are scarce resources, critical to humans. Developments in each affect the availability and cost of the others, and consequently human prosperity. Measures to limit greenhouse gas concentrations will inevitably exact dramatic changes on energy and land systems and in turn alter the character, magnitude and geographic distribution of human claims on water resources. We employ the Global Change Assessment Model (GCAM), an integrated assessment model to explore the interactions of energy, land and water systems in the context of alternative policies to limit climate change to three alternative levels: 2.5 Wm-2 (445 ppm CO2-e), 3.5 Wm-2 (535 ppm CO2-e) and 4.5 Wm-2 (645 ppm CO2-e). We explore the effects of alternative land-use emissions mitigation policy options—one which values terrestrial carbon emissions equally with fossil fuel and industrial emissions, and an alternative which places no penalty on land-use change emissions. We find that increasing populations and economic growth could be anticipated to lead to increased demand for water for agricultural systems (+200%), even in the absence of climate change. In general policies to mitigate climate change will increase agricultural demands for water, regardless of whether or not terrestrial carbon is valued or not. Burgeoning demands for water are driven by the demand for bioenergy in response to emissions mitigation policies. We also find that the policy matters. Increases in the demand for water when terrestrial carbon emissions go un-prices are vastly larger than when terrestrial system carbon emissions are prices at the same rate as fossil fuel and industrial emissions. Our estimates for increased water demands when terrestrial carbon systems go un-priced are larger than earlier studies. We find that the deployment of improved irrigation delivery systems could mitigate some of the increase in water demands, but cannot reverse the increases in water demands when terrestrial carbon

  4. Implications of "peak oil" for atmospheric CO2 and climate

    CERN Document Server

    Kharecha, P A

    2007-01-01

    Peaking of global oil production may have a large effect on future atmospheric CO2 amount and climate change, depending upon choices made for subsequent energy sources. We suggest that, if estimates of oil and gas reserves by the Energy Information Administration are realistic, it is feasible to keep atmospheric CO2 from exceeding approximately 450 ppm, provided that future exploitation of the huge reservoirs of coal and unconventional fossil fuels incorporates carbon capture and sequestration. Existing coal-fired power plants, without sequestration, must be phased out before mid-century to achieve this limit on atmospheric CO2. We also suggest that it is important to "stretch" oil reserves via energy efficiency, thus avoiding the need to extract liquid fuels from coal or unconventional fossil fuels. We argue that a rising price on carbon emissions is probably needed to keep CO2 beneath the 450 ppm ceiling.

    2009-11-01

    Full Text Available Modern Process Philosophy began when Alfred North Whitehead realized that existence is primarily vibratory, not points but processes. Vibrations are best understood as sound waves, or through using auditory metaphors rather than visual ones. Our Universe is more like music than matter, but how does this help us better understand it? In this paper I use the example of the large ocean current oscillators that help drive our climate systems to reveal the more effective nature of auditory approaches. Through an auditory approach, we can better understand the ways these oscillations constrain and interact with other levels of oscillations as well as how they might be destroyed by other levels. This can then lead to us extending our ethics to the conservation of these oscillations.

    A key challenge for resource and land managers is predicting the consequences of climate warming on streamflow and water resources. During the last century in the western United States, significant reductions in snowpack and earlier snowmelt have led to an increase in the fraction of annual streamflow during winter and a decline in the summer. However, this increase and decrease in streamflow is mediated by the climate and landscape. Here we explore key landscape and climate metrics for interpreting hydrologic sensitivity to climate using observed flow from a range of watersheds across the western United States. Our results indicate that the recession constant and fraction of precipitation falling as snow are the two primary controls on hydrologic sensitivity to climate in this region. Dry season flows in watersheds that drain slowly from deep groundwater and receive precipitation as snow are most sensitive to climate warming. In terms of peak flow, watersheds are most sensitivity to the consistency (i.e. signal-to-noise ratio) in fraction of precipitation falling as snow. Our results also indicate that not all trends in western United States are associated with changes in snowpack dynamics; we observe declining flow in late fall and winter in rain-dominated watersheds as well. These empirical findings support both theory and hydrologic modeling and have implications for how hydrologic sensitivity to climate change is evaluated and interpreted across broad regions.

    Developing nations incur a greater risk to climate change than the developed world due to poorly managed human/natural resources, unreliable infrastructure and brittle governing/economic institutions. These vulnerabilities often give rise to a climate induced “domino effect” of reduced natural resource production-leading to economic hardship, social unrest, and humanitarian crises. Integral to this cascading set of events is increased human migration, leading to the “spillover” of impacts to adjoining areas with even broader impact on global markets and security. Given the complexity of factors influencing human migration and the resultant spill-over effect, quantitative tools are needed to aid policy analysis. Toward this need, a series of migration models were developed along with a system dynamics model of the spillover effect. The migration decision models were structured according to two interacting paths, one that captured long-term “chronic” impacts related to protracted deteriorating quality of life and a second focused on short-term “acute” impacts of disaster and/or conflict. Chronic migration dynamics were modeled for two different cases; one that looked only at emigration but at a national level for the entire world; and a second that looked at both emigration and immigration but focused on a single nation. Model parameterization for each of the migration models was accomplished through regression analysis using decadal data spanning the period 1960-2010. A similar approach was taken with acute migration dynamics except regression analysis utilized annual data sets limited to a shorter time horizon (2001-2013). The system dynamics spillover model was organized around two broad modules, one simulating the decision dynamics of migration and a second module that treats the changing environmental conditions that influence the migration decision. The environmental module informs the migration decision, endogenously simulating interactions

    2016-01-01

    A transition to a fully global renewable energy infrastructure is potentially possible in no more than a few decades, even using current wind/solar technologies. We demonstrate that at its completion this transition would terminate anthropogenic carbon emissions to the atmosphere derived from energy consumption in roughly 25 years as well as double current global energy production. This result would provide all human energy needs worldwide and additional energy required for climate adaptation as well as carbon sequestration from the atmosphere to bring down the atmospheric carbon dioxide (CO2) concentration to safer levels. The implementation of this energy transition in the near future would maximize the probability for achieving a less than 2 deg C, with a potential 1.5 deg C limit, increase to global temperature over the pre-industrial level by 2100. Our best case scenario utilizes less than 3% of current annual global energy consumption per year with an annual reinvestment of 10% of its growing renewable ...

    The construction industry has hit a plateau in terms of safety performance. Safety climate is regarded as a leading indicator of safety performance; however, relatively little safety climate research has been done in the Canadian construction industry. Safety climate may be geographically sensitive, thus it is necessary to examine how the construct of safety climate is defined and used to improve safety performance in different regions. On the other hand, more and more attention has been paid to job related stress in the construction industry. Previous research proposed that individual resilience may be associated with a better safety performance and may help employees manage stress. Unfortunately, few empirical research studies have examined this hypothesis. This paper aims to examine the role of safety climate and individual resilience in safety performance and job stress in the Canadian construction industry. The research was based on 837 surveys collected in Ontario between June 2015 and June 2016. Structural equation modeling (SEM) techniques were used to explore the impact of individual resilience and safety climate on physical safety outcomes and on psychological stress among construction workers. The results show that safety climate not only affected construction workers' safety performance but also indirectly affected their psychological stress. In addition, it was found that individual resilience had a direct negative impact on psychological stress but had no impact on physical safety outcomes. These findings highlight the roles of both organizational and individual factors in individual safety performance and in psychological well-being. Construction organizations need to not only monitor employees' safety performance, but also to assess their employees' psychological well-being. Promoting a positive safety climate together with developing training programs focusing on improving employees' psychological health - especially post-trauma psychological

    We reconstruct Holocene climate history (last 10,000 years) for each of the U.S. National Park Service units in the western Great Lakes region in order to evaluate their sensitivity to global warming. Annual precipitation, annual temperature, and July and January temperatures were reconstructed by comparing fossil pollen in lake sediment with pollen in surface samples, assuming that ancient climates were similar to modern climate near analogous surface samples. In the early Holocene, most of the parks experienced colder winters, warmer summers, and lower precipitation than today. An exception is Voyageurs National Park in northern Minnesota where, by 8000 years ago, January temperatures were higher than today. The combination of high mean annual temperature and lower precipitation at Voyageurs resulted in a dry period between 8000 and 5000 years ago, similar to the Prairie Period in regions to the south and west. A mid-Holocene warm-dry period also occurred at other northern and central parks but was much less strongly developed. In southern parks there was no clear evidence of a mid-Holocene warm-dry period. These differences suggest that global model predictions of a warm, dry climate in the northern Great Plains under doubled atmospheric CO2 may be more applicable to Voyageurs than to the other parks. The contrast in reconstructed temperatures at Voyageurs and Isle Royale indicates that the ameliorating effect of the Great Lakes on temperatures has been in effect throughout the Holocene and presumably will continue in the future, thus reducing the potential for species loss caused by future temperature extremes. Increased numbers of mesic trees at all of the parks in the late Holocene reflect increasing annual precipitation. This trend toward more mesic conditions began 6000 years ago in the south and 4000 years ago in the north and increased sharply in recent millennia at parks located today in lake-effect snow belts. This suggests that lake-effect snowfall is

    Glaciers are frozen fresh water reservoirs that respond to changes in temperature and snow accumulation at the surface. Outside Greenland and Antarctica, Canada has the greatest concentration of glacier coverage. In western Canada, concern is growing about the impact that changes in glaciers, particularly reducing glacier melt in summer, may have on water resources. Canada's Arctic Glaciers, with an area of approximately 146,000 km2, are among the largest of the Arctic glaciers, and their possible contribution to sea level rise is not negligible. Regional Climate Models (RCM) are an important tool to assess the projected changes to climate, particularly due to its high resolution compared with GCMs. Recently, a dynamic glacier scheme, based on volume-area relationship, has been introduced in CRCM5. Both offline (i.e., glacier scheme and land surface scheme) and online (CRCM5 with the new glacier scheme) simulations were performed for the 2000-2100 period over a domain covering the glaciers of western and Arctic Canada. The offline simulations were driven by outputs from a CRCM5 transient climate change simulation, driven by CanESM2 at the lateral boundaries, for RCPs 4.5 and 8.5. This driving data shows an increase in winter precipitation for the Arctic region and a decrease over the west Canadian glaciers. Despite the increase in winter precipitation for the Arctic glacier regions, the offline simulations suggest significant decreases in glacier fraction for the region, suggesting that the gain of mass from the increase in precipitation over the Arctic Glaciers won't offset the glacier mass loss due to the temperature increase. Results also suggest significant decreases in glacier fraction and volume for the west Canadian glaciers. The results of the offline simulation will be confirmed with the coupled simulation, and the impact of retreating glaciers on the regional climate and hydrology will be presented based on the coupled simulation.

    Decisions for climate policy will need to take place in advance of climate science resolving all relevant uncertainties. Further, if the concern of policy is to reduce risk, then the best-estimate of climate change impacts may not be so important as the currently understood uncertainty associated with realizable conditions having high consequence. This study focuses on one of the most uncertain aspects of future climate change - precipitation - to understand the implications of uncertainty on risk and the near-term justification for interventions to mitigate the course of climate change. We show that the mean risk of damage to the economy from climate change, at the national level, is on the order of one trillion dollars over the next 40 years, with employment impacts of nearly 7 million labor-years. At a 1% exceedance-probability, the impact is over twice the mean-risk value. Impacts at the level of individual U.S. states are then typically in the multiple tens of billions dollar range with employment losses exceeding hundreds of thousands of labor-years. We used results of the Intergovernmental Panel on Climate Change's (IPCC) Fourth Assessment Report 4 (AR4) climate-model ensemble as the referent for climate uncertainty over the next 40 years, mapped the simulated weather hydrologically to the county level for determining the physical consequence to economic activity at the state level, and then performed a detailed, seventy-industry, analysis of economic impact among the interacting lower-48 states. We determined industry GDP and employment impacts at the state level, as well as interstate population migration, effect on personal income, and the consequences for the U.S. trade balance.

    Whether a journey is pleasant or not usually depends on the climatic conditions which permit to perform outdoor activities. The perception of climatic conditions, determined by physiological and psychological factors, can vary according to different adaptation phenomena related to the person involved and the weather conditions of the place where they live. Studying the bioclimatology of a country characterized by a high flux of tourism, as e.g. Italy, can provide some important information about where and when is it better to visit a place. Some differences have to be specified though, like the local tourism, which is used to that type of climate, and international tourism, which is formed by people coming from countries with different types of climates. Therefore this paper examined the climatic conditions and outdoor thermal comfort through the Mediterranean Outdoor Comfort Index (MOCI) for local tourism and through the predicted mean vote (PMV) for international tourism. The cities examined were three (Venice, Rome and Palermo located in the North, Centre and South of Italy, respectively), where average information were collected every week for an entire year. Finally, a map of the entire Italian territory reporting the seasonal average values of these indexes was also reported.

    Early in the pandemic, psychologists who engaged in HIV/AIDS research and practice or care relied more on their "general" psychological knowledge and training than on HIV/AIDS-specific information or training for combating the disease. In the past two decades much has been gained from the contributions of psychologists working in the areas of HIV/AIDS prevention and intervention. However, little is known regarding how the discipline prepares its students for a career in HIV/AIDS research and practice/care. One important venue for educating future psychologists is college-level textbooks because they are often the students' gateway to the scientific literature in psychology. Therefore, presentation of adequate and accurate information in these texts is critical. The present study involved a review and content analysis of introductory, clinical/counseling, health, human sexuality, and social/community psychology textbooks. It revealed that some level of information regarding HIV/AIDS was found in the majority of most college-level psychology texts that were reviewed. However, many books do not present a comprehensive overview or review of this problem, and do not adequately address the role psychology and behavior change can play in abating it. Implications for education, training, and practices are discussed.

  2. Implications of the Hidden Spatiotemporal Vulnerability of US Building Energy Demand to Climate Change

    2015-12-01

    Energy consumption in US buildings, accounting for 41% of primary energy consumption in 2010, is particularly vulnerable to climate change due to the direct relationship between space heating/cooling and outside temperature. Past assessments of climate change impacts on building energy consumption have neglected spatial variations in the "balance point" temperature and the extremes at smaller spatiotemporal scales, making the implications of local-scale vulnerability incomplete. Here we develop state-specific empirical relationships between building energy consumption and temperature to explore the vulnerability of building energy supply and demand under climate change. We find increases in summertime electricity demand exceeding 20% and decreases in wintertime non-electric energy demand of more than 30% in some states by the end of the century. When examined annually at the national scale, these extremes are hidden by numerical cancellation. The financial implications vary spatially with increases in total net building energy expenditures in some states (as much as 3 billion/year) while in others, costs decline (as much as 1 billion/year). Integrated across the contiguous US, these variations result in a net savings of roughly 1.4 billion/year. However, this must be weighed against the cost of adding electricity generation capacity ranging from 13.9 billion/year to 52.2 billion/year in order to maintain the electricity grid's reliability in summer. These results have wide implications for climate policy, the social cost of carbon and energy supply planning. It also demonstrates the importance of representing the climate change impacts on energy consumption at scales relevant to human decisions and actions.Energy consumption in US buildings, accounting for 41% of primary energy consumption in 2010, is particularly vulnerable to climate change due to the direct relationship between space heating/cooling and outside temperature.

    As an integral part of the National Climate Assessment (NCA), technical assessment reports for 13 regions in the U.S. that describe the scientific rationale to support climate change impacts within the purview of these regions, and provide adaptation or mitigation measures in response to these impacts. These technical assessments focus on climate change impacts on sectors that are important environmental, biophysical, and social and economic aspects of sustainability within the U.S.: Climate change science, Ecosystems and biodiversity, Water resources, Human health, Energy supply and use, Water/energy/land use, Transportation, Urban/infrastructure/vulnerability, Agriculture, Impacts of climate change on tribal/indigenous and native lands and resources, Forestry, Land use/land cover change, Rural communities development, and Impacts on biogeochemical cycles, with implications for ecosystems and biodiversity. There is a critical and timely need for the development of mitigation and adaptation strategies in response to climate change by the policy and decision making communities, to insure resiliency and sustainability of the built environment in the future.

    Recently, attention has been drawn towards black carbon aerosols as a likely short-term climate warming mitigation candidate. However the global and regional impacts of the direct, cloud-indirect and semi-direct forcing effects are highly uncertain, due to the complex nature of aerosol evolution and its climate interactions. Black carbon is directly released as particle into the atmosphere, but then interacts with other gases and particles through condensation and coagulation processes leading to further aerosol growth, aging and internal mixing. A detailed aerosol microphysical scheme, MATRIX, embedded within the global GISS modelE includes the above processes that determine the lifecycle and climate impact of aerosols. This study presents a quantitative assessment of the impact of microphysical processes involving black carbon, such as emission size distributions and optical properties on aerosol cloud activation and radiative forcing. Our best estimate for net direct and indirect aerosol radiative forcing change is -0.56 W/m{sup 2} between 1750 and 2000. However, the direct and indirect aerosol effects are very sensitive to the black and organic carbon size distribution and consequential mixing state. The net radiative forcing change can vary between -0.32 to -0.75 W/m{sup 2} depending on these carbonaceous particle properties. Assuming that sulfates, nitrates and secondary organics form a coating shell around a black carbon core, rather than forming a uniformly mixed particles, changes the overall net radiative forcing from a negative to a positive number. Black carbon mitigation scenarios showed generally a benefit when mainly black carbon sources such as diesel emissions are reduced, reducing organic and black carbon sources such as bio-fuels, does not lead to reduced warming.

    Full Text Available Changes in Switzerland's climate are expected to have major impacts on glaciers, the hydrological regime and the natural hazard potential in mountainous regions. Glacier de la Plaine Morte is the largest plateau glacier in the European Alps and thus represents a particularly interesting site for studying rapid and far-reaching effects of atmospheric warming on Alpine glaciers. Based on detailed field observations combined with numerical modelling, the changes in total ice volume of Glacier de la Plaine Morte since the 1950s and the dynamics of present glacier mass loss are assessed. Future ice melt and changes in glacier runoff are computed using climate scenarios, and a possible increase in the natural hazard potential of glacier-dammed lakes around Plaine Morte over the next decades is discussed. This article provides an integrative view of the past, current and future retreat of an extraordinary Swiss glacier and emphasizes the implications of climate change on Alpine glaciers.

    To identify the contributions of medical conditions and psychological distress to well-being within a non-clinical sample, stratified by age. It was predicted that medical conditions and psychological distress would be negatively associated with well-being. It was also predicted that psychological distress and medical conditions would account for significant variance in well-being. It was further predicted that psychological distress would mediate the relationship between medical conditions and well-being across the life span. 1,424,307 employees/health plan members that completed an HRA. SEM was used to characterize relationships among medical conditions and psychological distress in predicting well-being (QoL, HRQoL, and impairments in ADLs) in five adult age groups. Medical conditions and psychological distress were negatively associated with well-being. As age increased, psychological distress was less associated with well-being. However, in those >75 years old, psychological distress had the largest association with well-being. All medical conditions, except cancer, were negatively associated with well-being. There were decreasing effects of medical conditions across the life span, with the exception of pulmonary disease which increased. Psychological distress mediated the relationship between medical conditions and well-being, with chronic pain having the greatest mediation across the life span. The analysis revealed differences in the contribution of psychological distress and medical conditions to well-being by age group. Additionally, the contribution of psychological distress was equitable to that of medical conditions, thus highlighting the importance of addressing psychological distress in medical populations for well-being. Findings suggest the relevance of age in well-being and the need for further longitudinal investigation.

    2016-12-01

    On-going research in climate science communication through environmental media has uncovered critical barriers to reducing denial and increasing agency in addressing the threat of climate change. Similar to framing of our changing environment as "global warming", the term "climate change" also fails to properly frame the most critical challenge our species has faced. In a set of preliminary studies, significant changes in climate crisis denial, both positive and negative, have resulted from different media messaging. Continuation of this research utilizes social judgement theory (SJT) to classify a broader spectrum of effective avenues for environmental communication. The specificity of the terms global warming and climate change limit inclusion of issues critical to understanding their impacts. Now that the masses know what climate change is, it's time to teach them what it means.

    Glacier fluctuations exclusively due to internal variations in the climate system are simulated using downscaled integrations of the ECHAM4/OPYC coupled general circulation model (GCM). A process-based modeling approach using a mass balance model of intermediate complexity and a dynamic ice flow model considering simple shearing flow and sliding are applied. Multi-millennia records of glacier length fluctuations for Nigardsbreen (Norway) and Rhonegletscher (Switzerland) are simulated using auto-regressive processes determined by statistically downscaled GCM experiments. Return periods and probabilities of specific glacier length changes using GCM integrations excluding external forcings such as solar irradiation changes, volcanic or anthropogenic effects are analyzed and compared to historical glacier length records. Preindustrial fluctuations of the glaciers as far as observed or reconstructed, including their advance during the ''Little Ice Age'', can be explained by internal variability in the climate system as represented by a GCM. However, fluctuations comparable to the present-day glacier retreat do not occur in the GCM control experiments and must be caused by external forcing, with anthropogenic forcing being a likely candidate.

    In this paper, we discuss past climatic trends over India, greenhouse gas emissions due to energy consumption, forest and land-use changes, climate change scenarios for the year 2050, potential consequences for agriculture and cyclone activity and the possibility that India might limit the increasing trend in its emissions. India's mean surface air temperature has increased significantly by about 0.4°C over the past ccntury. Neither monsoon nor annual rainfall shows any significant trend. On average, there has been a rise in sea levels around India over recent decades, though considerable uncertainties exist in the accuracy and interpretation of the available data. Carbon emissions from the energy sector amount to 71 MT a year, equivalent to all other sectors combined. From land-use data, a marginal net sequestration of 5.25 million tonnes of carbon occurred during 1986. Following the IPCC guidelines, methane emissions from rice and livestock are estimated at 17.4 and 12.8 Tg/year, respectively. According to recent climate model projections, India may experience a further rise in temperature of 1 °C by the year 2050, about four times the rate of warming experienced over the past 100 years. A modest increase in precipitation amounts might occur. Cereals production is estimated to decrease and the nutrition security of the population-rich but land-hungry region of India might be hampered. An increase in local tropical cyclone activity may occur over thc next century, posing added problems as large areas in the coastal regions have a dense population. About 70% of the electricity generation in India is from coal-based power stations. Altering this dependence significantly to reduce emissions would imply a substantial change in the present energy policy of India. There is great potential for improving energy efficiency and conservation. The adoption of cleaner coal-technologies should be considered, as must the development of renewable, non-conventional energy

    2018-02-08

    Through a systematic search of English language peer-reviewed studies, we assess how health professionals and the public, worldwide, perceive the health implications of climate change. Among health professionals, perception that climate change is harming health appears to be high, although self-assessed knowledge is low, and perceived need to learn more is high. Among the public, few North Americans can list any health impacts of climate change, or who is at risk, but appear to view climate change as harmful to health. Among vulnerable publics in Asia and Africa, awareness of increasing health harms due to specific changing climatic conditions is high. Americans across the political and climate change opinion spectra appear receptive to information about the health aspects of climate change, although findings are mixed. Health professionals feel the need to learn more, and the public appears open to learning more, about the health consequences of climate change.

  18. Influence of smallholder farmers’ perceptions on adaptation strategies to climate change and policy implications in Zimbabwe

    Full Text Available Smallholder agricultural production is largely affected by climate change and variability. Despite the negative effects brought by climate variability, smallholder farmers are still able to derive livelihoods. An understanding of factors that influence farmers’ responses and adaptation to climate variability can improve decision making for governments and development partners. This study investigated farmers’ perceptions and adaptation strategies to climate change and how these influence adaptation policies at local level. A survey was conducted with 100 households randomly selected from Chiredzi district. Data collected was used to derive farmer perceptions to climate change as well as the influence of their perceptions and subsequent adaptation methods to ensuing local agricultural adaptation measures and policies. The results indicated that smallholder farmers perceived general reduction in long-term annual rainfall and rising local average temperatures. Adverse trends in rainfall and average temperature perceived by farmers were consistent with empirical data. These perceptions and other socio-economic factors helped to shape smallholder farmer agricultural adaptation strategies. Policy implications are that the government and development partners should seek ways to assist autonomous adaptations by farmers through investments in planned adaptation initiatives.

  20. Farmers’ Adaptation Strategies to Climate Change and Their Implications in the Zou Department of South Benin

    Full Text Available Climate change is a global phenomenon. Its impact on agricultural activities in developing countries has increased dramatically. Understanding how farmers perceive climate change and how they adapt to it is very important to the implementation of adequate policies for agricultural and food security. This paper aims to contribute to an understanding of farmers’ adaptation choices, determinants of the adaptation choices and the long-term implications of the adaptation choices. Data were collected from 120 respondents in the Zou Department of Benin. A binary logit model was used to analyze the factors influencing household decisions to adapt to climate change. Multinomial logistic regression analysis was estimated to analyze the factors influencing households’ choice of adaptation strategies to climate change. The results show that farmers have a developed perception of climate change. These changes are translated by rainfall disturbances (rainfall delays, early cessation, bad rainfall distribution etc., shortening of the small dry season, increasing of temperature and sometimes, violent winds. The survey reveals that Benin farmers adopt many strategies in response to climate change. These strategies include “Crop–livestock diversification and other good practices (mulching, organic fertilizer,” “Use of improved varieties, chemical fertilizers and pesticides,” “Agroforestry and perennial plantation” and “Diversification of income-generating activities.” The findings also reveal that most of the respondents use these strategies in combination. From the binary logit model, we know that “farming experience” and “educational level of household head” positively influence adaptation decisions. The result of the multinomial logit analysis shows that farming experience, educational level, farm size and gender have a significant impact on climate change adaptation strategies. Based on in-depth analysis of each strategy, we

    Global climate change will undoubtedly be a pressure on coastal marine ecosystems, affecting not only species distributions and physiology but also ecosystem functioning. In the coastal zone, the environmental variables that may drive ecological responses to climate change include temperature, wave energy, upwelling events and freshwater inputs, and all act and interact at a variety of spatial and temporal scales. To date, we have a poor understanding of how climate-related environmental changes may affect coastal marine ecosystems or which environmental variables are likely to produce priority effects. Here we use time series data (17 years) of coastal benthic macrofauna to investigate responses to a range of climate-influenced variables including sea-surface temperature, southern oscillation indices (SOI, Z4), wind-wave exposure, freshwater inputs and rainfall. We investigate responses from the abundances of individual species to abundances of functional traits and test whether species that are near the edge of their tolerance to another stressor (in this case sedimentation) may exhibit stronger responses. The responses we observed were all nonlinear and some exhibited thresholds. While temperature was most frequently an important predictor, wave exposure and ENSO-related variables were also frequently important and most ecological variables responded to interactions between environmental variables. There were also indications that species sensitive to another stressor responded more strongly to weaker climate-related environmental change at the stressed site than the unstressed site. The observed interactions between climate variables, effects on key species or functional traits, and synergistic effects of additional anthropogenic stressors have important implications for understanding and predicting the ecological consequences of climate change to coastal ecosystems. © 2015 John Wiley & Sons Ltd.

    2016-04-01

    Here we present an interdisciplinary study on land use changes in Northern Italy at the transition from the Roman Empire to the Early Middle Ages. The combination of archaeological data and high-resolution pollen analyses carried out in the Fiavè basin (Trentino) provide a detailed insight in socio-economic changes and its implications with climate in the Dark Ages. The vegetation in this area is dominated up to 1000 m by submediterranian trees like Fraxinus ornus and Ostrya carpinifolia, superseded by a mixed Fagus and Abies forest with variable amounts of Picea abies. Since 2008 archaeological surveys in the Fiavè basin as well as excavations conducted on a fortified hill-top settlement (castrum) in 985m register the settlement development of this settlement cluster and reveal an almost continuous occupation from Roman to Early Medieval Times. In addition a high-resolution pollen record from a 1.30 m thick peat sequence of the bog "Palude di Fiave" discloses four main phases: (1) in the Late Iron Age high amounts of arboreal pollen and the spread of Abies demonstrate a decrease in settlement activity suggested by wetter climate conditions. (2) During the Roman Empire a phase with arable farming in the basin starts. Olea, Juglans and Castanea sativa are introduced and document the onset of horticulture in this region. (3) After 300 AD - during the Migration Period - the wet and cool conditions have had poor impact on settlement activity. Agricultural (Cerealia) and nitrophilous indicators (Plantago, Chenopodiaceae, Urticaceae) are continuously proved. However a change within the cultivated crops in relation to the climate conditions is observed. Subsequently a progressive recovery of Pinus followed by Abies and Fagus marks the climatic improvement at the beginning of the Early Medieval Times. (4) The time from 600 to 800 AD is characterized by increasing frequency and diversity of anthropogenic-related indicators. The implications of these land use changes with

    The Goddard Earth Observing System Chemistry Climate Model (GEOS CCM) has been developed by combining the atmospheric chemistry and transport modules developed over the years at Goddard and the GEOS general circulation model, also developed at Goddard. The first version of the model was used in the CCMVal intercomparison exercises that contributed to the 2006 WMO/UNEP Ozone Assessment. The second version incorporates the updated version of the GCM (GEOS 5) and will be used for the next round of CCMVal evaluations and the 2010 Ozone Assessment. The third version, now under development, incorporates the combined stratosphere and troposphere chemistry package developed under the Global Modeling Initiative (GMI). We will show comparison to past observations that indicate that we represent the ozone trends over the past 30 years. We will also show the basic temperature, composition, and dynamical structure of the simulations. We will further show projections into the future. We will show results from an ensemble of transient and time-slice simulations, including simulations with fixed 1960 chlorine, simulations with a best guess scenario (Al), and simulations with extremely high chlorine loadings. We will discuss planned extensions of the model to include emission-based boundary conditions for both anthropogenic and biogenic compounds.

    The influence of recent climate change on the world's biota has manifested broadly, resulting in latitudinal range shifts, advancing dates of arrival of migrants and onset of breeding, and altered community relationships. Climate change elevates conservation concerns worldwide because it will likely exacerbate a broad range of identified threats to animal populations. In the past few decades, grassland birds have declined faster than other North American avifauna, largely due to habitat threats such as the intensification of agriculture. We examine the effects of local climatic variations on the breeding performance of a bird endemic to the shortgrass prairie, the Lark Bunting (Calamospiza melanocorys) and discuss the implications of our findings relative to future climate predictions. Clutch size, nest survival, and productivity all positively covaried with seasonal precipitation; yet relatively intense daily precipitation events temporarily depressed daily survival of nests. Nest survival was positively related to average temperatures during the breeding season. Declining summer precipitation may reduce the likelihood that Lark Buntings can maintain stable breeding populations in eastern Colorado although average temperature increases of up to 3 degrees C (within the range of this study) may ameliorate declines in survival expected with drier conditions. Historic climate variability in the Great Plains selects for a degree of vagility and opportunism rather than strong site fidelity and specific adaptation to local environments. These traits may lead to northerly shifts in distribution if climatic and habitat conditions become less favorable in the drying southern regions of the Great Plains. Distributional shifts in Lark Buntings could be constrained by future changes in land use, agricultural practices, or vegetative communities that result in further loss of shortgrass prairie habitats.

    The structure and function of Alaska's forests have changed significantly in response to a changing climate, including alterations in species composition and climate feedbacks (e.g., carbon, radiation budgets) that have important regional societal consequences and human feedbacks to forest ecosystems. In this paper we present the first comprehensive synthesis of climate-change impacts on all forested ecosystems of Alaska, highlighting changes in the most critical biophysical factors of each region. We developed a conceptual framework describing climate drivers, biophysical factors and types of change to illustrate how the biophysical and social subsystems of Alaskan forests interact and respond directly and indirectly to a changing climate. We then identify the regional and global implications to the climate system and associated socio-economic impacts, as presented in the current literature. Projections of temperature and precipitation suggest wildfire will continue to be the dominant biophysical factor in the Interior-boreal forest, leading to shifts from conifer- to deciduous-dominated forests. Based on existing research, projected increases in temperature in the Southcentral- and Kenai-boreal forests will likely increase the frequency and severity of insect outbreaks and associated wildfires, and increase the probability of establishment by invasive plant species. In the Coastal-temperate forest region snow and ice is regarded as the dominant biophysical factor. With continued warming, hydrologic changes related to more rapidly melting glaciers and rising elevation of the winter snowline will alter discharge in many rivers, which will have important consequences for terrestrial and marine ecosystem productivity. These climate-related changes will affect plant species distribution and wildlife habitat, which have regional societal consequences, and trace-gas emissions and radiation budgets, which are globally important. Our conceptual framework facilitates

    During the next 100 years, the mean annual temperature is expected to be 1-6 deg C higher than at present. It is also expected to be accompanied by a lengthening of the thermal growing season and increased precipitation. Consequently, climatic change will increase the uncertainty of the management of forest ecosystems in the future. In this context, this research project aimed to outline the ecological and silvicultural implications of climatic change with regard to (1) how the expected climatic change might modify the functioning and structure of the boreal forest ecosystem, and (2) how the silvicultural management of the forest ecosystem should be modified in order to maintain sustainable forest yield under changing climatic conditions. The experimental component of the project concerned first the effect that elevating temperature and elevating concentration of atmospheric carbon have on the ontogenetic development of Scots pine (Pinus sylvestris L) and on the subsequent increase in frost damage during winter. The second part of the study looked the effect of elevating temperature and elevating concentration of atmospheric carbon on the growth of Scots pine through photosynthesis, respiration, transpiration, nutrient supply, and changes in crown structure. This experiment was utilised in several subprojects of the overall project

    Species distribution models (SDMs) have been criticized for involving assumptions that ignore or categorize many ecologically relevant factors such as dispersal ability and biotic interactions. Another potential source of model error is the assumption that species are ecologically uniform in their climatic tolerances across their range. Typically, SDMs to treat a species as a single entity, although populations of many species differ due to local adaptation or other genetic differentiation. Not taking local adaptation into account, may lead to incorrect range prediction and therefore misplaced conservation efforts. A constraint is that we often do not know the degree to which populations are locally adapted, however. Lacking experimental evidence, we still can evaluate niche differentiation within a species' range to promote better conservation decisions. We explore possible conservation implications of making type I or type II errors in this context. For each of two species, we construct three separate MaxEnt models, one considering the species as a single population and two of disjunct populations. PCA analyses and response curves indicate different climate characteristics in the current environments of the populations. Model projections into future climates indicate minimal overlap between areas predicted to be climatically suitable by the whole species versus population-based models. We present a workflow for addressing uncertainty surrounding local adaptation in SDM application and illustrate the value of conducting population-based models to compare with whole-species models. These comparisons might result in more cautious management actions when alternative range outcomes are considered.

    In recent discussions regarding concerns about the academic achievement of US students, educational policy makers have suggested the implementation of certain teacher policies. To address the limited empirical research on the putative educational impact of such policies, this study used multilevel structural equation models to investigate the longitudinal associations between teacher evaluation and reward policies, and student mathematics achievement and dropout with a national sample of students (n = 7,779) attending one of 431 public high schools. The student sample included an equal number of boys and girls averaging 16 years of age, and included a White (53%) majority. This study examined whether associations between teacher policies and student achievement were mediated by the teacher-student relationship climate. Results of this study were threefold. First, teacher evaluation policies that allowed students to evaluate their teachers were associated with more positive student reports of the classroom teaching climate. Second, schools with teacher reward policies that included assigning higher performing teachers with higher performing students had a negative association with student perceptions of the teaching climate. Lastly, schools with better student perceptions of the teaching climate were associated with lower student dropout rates by students' senior year. These findings are discussed in light of their educational policy implications.

    The climate in Timor Leste (East Timor) is predicted to become about 1.5 °C warmer and about 10 % wetter on average by 2050. By the same year, the population is expected to triple from 1 to 2.5-3 million. This article maps the predicted changes in temperature and rainfall and reviews the implications of climate change and population growth on agricultural systems. Improved cultivars of maize, rice, cassava, sweet potato and peanuts with high yield performance have been introduced, but these will need to be augmented in the future with better adapted cultivars and new crops, such as food and fodder legumes and new management practices. The requirements for fertilizers to boost yields and terracing and/or contour hedgerows to prevent soil erosion of steeply sloping terrain are discussed. Contour hedges can also be used for fodder for improved animal production to provide protein to reduce malnutrition.

    Full Text Available This study examined the extent to which job conditions (job demands and job control, psychological climate, and affective commitment predict turnover intention among Tellers and Interpersonal Relation Officers in some Nigerian Banks and whether affective commitment mediate the relationship between psychological climate and turnover intention. Five hundred and nineteen(tellers = 321, IRO = 198bank employees (266 males and 253 females whose ages ranged from 19 to 65 years with a mean of 34.02 years and SD of 9.54, from 11 commercial banks in Lagos, Nigeria participated in the study. Validated scales were used for data collections. The study hypotheses were tested using hierarchical multiple regression, Baron and Kenny’s (1986 mediation analysis, and t-independent sample analyses. The results revealed significant joint and independent influence of job demands, job control, psychological climate, and affective commitment on turnover intention of bank employees. Furthermore, affective commitment directly and fully mediated the relationship between psychological climate and intention to quit. The results also revealed that interpersonal relation officers (IRO showed higher tendency to quit their jobs than tellers. The researchers therefore suggested the need for bank management to modify or re-design the aspect of the job taxing their employees and invest and create positive climate that would improve their employees’ well-being.

    2016-01-01

    Psychological research has provided essential insights into how stigma operates to disadvantage those who are targeted by it. At the same time, stigma research has been criticized for being too focused on the perceptions of stigmatized individuals and on micro-level interactions, rather than attending to structural forms of stigma. This article describes the relatively new field of research on structural stigma, which is defined as societal-level conditions, cultural norms, and institutional policies that constrain the opportunities, resources, and wellbeing of the stigmatized. I review emerging evidence that structural stigma related to mental illness and sexual orientation (1) exerts direct and synergistic effects on stigma processes that have long been the focus of psychological inquiry (e.g., concealment, rejection sensitivity); (2) serves as a contextual moderator of the efficacy of psychological interventions; and (3) contributes to numerous adverse health outcomes for members of stigmatized groups—ranging from dysregulated physiological stress responses to premature mortality—indicating that structural stigma represents an under-recognized mechanism producing health inequalities. Each of these pieces of evidence suggests that structural stigma is relevant to psychology and therefore deserves the attention of psychological scientists interested in understanding and ultimately reducing the negative effects of stigma.

    2014-01-01

    This article provides an illustrative overview of neurophysiological changes related to acute and chronic pain involving structural and functional brain changes, which might be the targets of psychological interventions. A number of psychological pain treatments have been examined with respect to their effects on brain activity, ranging from cognitive- and operant behavioral interventions, meditation and hypnosis, to neuro- and biofeedback, discrimination training, imagery and mirror treatment, as well as virtual reality and placebo applications. These treatments affect both ascending and descending aspects of pain processing and act through brain mechanisms that involve sensorimotor areas as well as those involved in affective-motivational and cognitive-evaluative aspects. The analysis of neurophysiological changes related to effective psychological pain treatment can help to identify subgroups of patients with chronic pain who might profit from different interventions, can aid in predicting treatment outcome, and can assist in identifying responders and nonresponders, thus enhancing the efficacy and efficiency of psychological interventions. Moreover, new treatment targets can be developed and tested. Finally, the use of neurophysiological measures can also aid in motivating patients to participate in psychological interventions and can increase their acceptance in clinical practice.

    Projections of health risks of climate change are surrounded with uncertainties in knowledge. Understanding of these uncertainties will help the selection of appropriate adaptation policies. We made an inventory of conceivable health impacts of climate change, explored the type and level of uncertainty for each impact, and discussed its implications for adaptation policy. A questionnaire-based expert elicitation was performed using an ordinal scoring scale. Experts were asked to indicate the level of precision with which health risks can be estimated, given the present state of knowledge. We assessed the individual scores, the expertise-weighted descriptive statistics, and the argumentation given for each score. Suggestions were made for how dealing with uncertainties could be taken into account in climate change adaptation policy strategies. The results showed that the direction of change could be indicated for most anticipated health effects. For several potential effects, too little knowledge exists to indicate whether any impact will occur, or whether the impact will be positive or negative. For several effects, rough 'order-of-magnitude' estimates were considered possible. Factors limiting health impact quantification include: lack of data, multi-causality, unknown impacts considering a high-quality health system, complex cause-effect relations leading to multi-directional impacts, possible changes of present-day response-relations, and difficulties in predicting local climate impacts. Participants considered heat-related mortality and non-endemic vector-borne diseases particularly relevant for climate change adaptation. For possible climate related health impacts characterised by ignorance, adaptation policies that focus on enhancing the health system's and society's capability of dealing with possible future changes, uncertainties and surprises (e.g. through resilience, flexibility, and adaptive capacity) are most appropriate.

    This study used a longitudinal, multi-method design to examine whether teens’ perceptions of maternal psychological control predicted lower levels of adolescent autonomy displayed with their mothers and peers over time. Significant predictions from teens’ perceptions of maternal psychological control to teens’ displays of autonomy in maternal and peer relationships were found at age 16 after accounting for adolescent displays of autonomy with mothers and peers at age 13, indicating relative changes in teens’ autonomy displayed with their mother and a close peer over time. Results suggest that the ability to assert one’s autonomy in mid-adolescence may be influenced by maternal behavior early in adolescence, highlighting the importance of parents minimizing psychological control to facilitate autonomy development for teens.

Significant predictions from teens' perceptions of maternal psychological control to teens' displays of autonomy in maternal and peer relationships were found at age 16 after accounting for adolescent displays of autonomy with mothers and peers at age 13, indicating relative changes in teens' autonomy displayed with their mother and a close peer over time. Results suggest that the ability to assert one's autonomy in mid-adolescence may be influenced by maternal behavior early in adolescence, highlighting the importance of parents minimizing psychological control to facilitate autonomy development for teens.

    Full Text Available Halley M Pontes, Daria J Kuss, Mark D Griffiths International Gaming Research Unit, Psychology Division, Nottingham Trent University, Nottingham, UK Abstract: Research into Internet addiction (IA has grown rapidly over the last decade. The topic has generated a great deal of debate, particularly in relation to how IA can be defined conceptually as well as the many methodological limitations. The present review aims to further elaborate and clarify issues that are relevant to IA research in a number of areas including: definition and characterization, incidence and prevalence rates, associated neuronal processes, and implications for treatment, prevention, and patient-specific considerations. It is concluded that there is no consensual definition for IA. Prevalence rates among nationally representative samples across several countries vary greatly (from 1% to 18.7%, most likely reflecting the lack of methodological consistency and conceptual rigor of the studies. The overlaps between IA and other more traditional substance-based addictions and the possible neural substrates implicated in IA are also highlighted. In terms of treatment and prevention, both psychological and pharmacological treatments are examined in light of existing evidence alongside particular aspects inherent to the patient perspective. Based on the evidence analyzed, it is concluded that IA may pose a serious health hazard to a minority of people.

    Research on the sexuality of Asians and Latinos in the United States has been sparse, and the studies that have been done suffer from a number of limitations. Using data from the National Latino and Asian American Study (2002-2003), this study examined self-identified sexual orientation and self-reported sexual behavior among Latinos (n = 2,554; age: M = 38.1, SE = 0.5) and Asians (n = 2,095; age: M = 41.5, SE = 0.8). This study also investigated implications for unfair treatment and psychological distress among sexual minorities identified in the sample. Results indicated heterogeneity in responses to items assessing sexual orientation and sexual behavior including differences in the adoption of lesbian, gay, or bisexual (LGB) identity by gender, ethnicity, nativity, and socioeconomic status. LGB sexual minorities reported higher levels of unfair treatment and psychological distress compared to their non-LGB-identified sexual minority counterparts, and unfair treatment was positively associated with psychological distress. Results highlight the need to consider multiple demographic factors in assessing sexuality, and also suggest that measures of both self-identified sexual orientation and sexual behavior should be collected. In addition, findings provide support for the deleterious influence of unfair treatment among Asians and Latinos in the United States.

  1. Supported Decision-Making: Implications from Positive Psychology for Assessment and Intervention in Rehabilitation and Employment.

    2017-12-01

    Purpose This article reviews existing literature on positive psychology, supported decision-making (SDM), employment, and disability. It examines interventions and assessments that have been empirically evaluated for the enhancement of decision-making and overall well-being of people with disabilities. Additionally, conceptual themes present in the literature were explored. Methods A systematic review was conducted across two databases (ERIC and PsychINFO) using various combination of keywords of 'disabilit*', work rehabilitation and employment terms, positive psychology terms, and SDM components. Seven database searches were conducted with diverse combinations of keywords, which identified 1425 results in total to be screened for relevance using their titles and abstracts. Database search was supplemented with hand searches of oft-cited journals, ancestral search, and supplemental search from grey literature. Results Only four studies were identified in the literature targeting SDM and positive psychology related constructs in the employment and job development context. Results across the studies indicated small to moderate impacts of the assessment and interventions on decision-making and engagement outcomes. Conceptually there are thematic areas of potential overlap, although they are limited in the explicit integration of theory in supported decision-making, positive psychology, disability, and employment. Conclusion Results suggest a need for additional scholarship in this area that focuses on theory development and integration as well as empirical work. Such work should examine the potential utility of considering positive psychological interventions when planning for SDM in the context of career development activities to enhance positive outcomes related to decision-making, self-determination, and other positive psychological constructs.

    Research concerning the psychosocial aspects of infertility and infertility treatment focuses more often on women than men. The aim of this review was to synthesize the English-language evidence related to the psychological and social aspects of infertility in men and discuss the implications of these reports for clinical care and future research. A structured search identified 73 studies that reported data concerning the desire for fatherhood and the psychological and social aspects of diagnosis, assisted reproductive technology (ART) treatment and unsuccessful treatment among men with fertility difficulties. The studies are diverse in conceptualisation, design, setting and data collection, but the findings were reasonably consistent. These studies indicated that fertile and infertile childless men of reproductive age have desires to experience parenthood that are similar to those of their female counterparts; in addition, diagnosis and initiation of treatment are associated with elevated infertility-specific anxiety, and unsuccessful treatment can lead to a state of lasting sadness. However, rates of clinically significant mental health problems among this patient population are no higher than in the general population. Infertile men who are socially isolated, have an avoidant coping style and appraise stressful events as overwhelming, are more vulnerable to severe anxiety than men without these characteristics. Men prefer oral to written treatment information and prefer to receive emotional support from infertility clinicians rather than from mental health professionals, self-help support groups or friends. Nevertheless, structured, facilitated psycho-educational groups that are didactic but permit informal sharing of experiences might be beneficial. There are gaps in knowledge about factors governing seeking, persisting with and deciding to cease treatment; experiences of invasive procedures; parenting after assisted conception; adoption and infertility

    2008-06-01

    Since the 1990s, sport and aging is increasingly in the focus of psychological research. Besides motivational aspects the main attention lies on the positive influence of sporting activity on physical and psychological health. Thus, ageing and sports is mostly considered under functional aspects. The aim to compensate deficits through sports in the elderly reflects the socially widespread pictures of age (frailness) and sport (capability, youthfulness). In this article the deficit model with the associated clichés is questioned on the background of the latest research. The author argues for a more differentiated and constructive view on sport and aging and to take into consideration the specific needs of older people.

    Impact of climate change on the water resources of the United States exposes the vulnerability of feedstock-specific mandated fuel targets to extreme weather conditions that could become more frequent and intensify in the future. Consequently, a sustainable biofuel policy should consider a) how climate change would alter both water supply and demand and, b) in turn, how related changes in water availability will impact the production of biofuel crops and c) the environmental implications of large scale biofuel productions. Since, understanding the role of biofuels in the water cycle is key to understanding many of the environmental impacts of biofuels, the focus of this study is on modeling the rarely explored interactions between land use, climate change, water resources and the environment in future biofuel production systems to explore the impacts of the US biofuel policy and climate change on water and agricultural resources. More specifically, this research will address changes in the water demand and availability, soil erosion and water quality driven by both climate change and biomass feedstock production in the Upper Mississippi River Basin. We used the SWAT (Soil and Water Assessment Tool) hydrologic model to analyze the water quantity and quality consequences of land use and land management related changes in cropping conditions (e.g. more use of marginal lands, greater residue harvest, increased yields), plus management practices due to biofuel crops to meet the RFS target on water quality and quantity. Results show that even if the Upper Mississippi River Basin is a region of low water stress, it contributes to high nutrient load in Gulf of Mexico through seasonal shifts in streamflow, changes in extreme high and low flow events, changes in loadings and transport of sediments and nutrients due to changes in precipitation patterns and intensity, changes in frequency of occurrence of floods and drought, early melting of snow and ice, increasing

  7. Implications of free will beliefs for basic theory and societal benefit: critique and implications for social psychology.

    Science.gov (United States)

    Vonasch, Andrew J; Baumeister, Roy F

    2013-06-01

    Greater belief in free will is associated with greater empathy towards the working poor, support for social mobility, greater desire for socio-economic equality, and less belief that poor people are fated to live in poverty. We found no sign that belief in free will led to prejudice or discrimination against poor people or undercut justice. These findings from an online survey flatly contradict the claims made by James Miles (2013). Belief in a just world did produce many of the patterns Miles attributed to belief in free will. We also question the reasoning and the strength of the purported evidence in his article, and we recommend that future writers on the topic should cultivate cautious, open-minded consideration of competing views. Miles' article is a useful reminder that to some writers, the topic of free will elicits strong emotional reactions. ©2012 The British Psychological Society.

    Agriculture is the largest employment sector in India, where food productivity, and thus food security, is highly dependent on seasonal rainfall and temperature. Projected increase in temperature, along with less frequent but intense rainfall events, will have a negative impact on crop productivity in India in the coming decades. These changes, along with continued ground water depletion, could have serious implications for Indian smallholder farmers, who are among some of the most vulnerable communities to climatic and economic changes. Hence baseline information on agricultural sensitivity to climate variability is important for strategies and policies that promote adaptation to climate variability. This study examines how cropping patterns in different agro-ecological zones in India respond to variations in precipitation and temperature. We specifically examine: a) which climate variables most influence crop cover for monsoon and winter crops? and b) how does the sensitivity of crop cover to climate variability vary in different agro-ecological regions with diverse socio-economic factors? We use remote sensing data (2000-01 - 2012-13) for cropping patterns (developed using MODIS satellite data), climate parameters (derived from MODIS and TRMM satellite data) and agricultural census data. We initially assessed the importance of these climate variables in two agro-ecoregions: a predominantly groundwater irrigated, cash crop region in western India, and a region in central India primarily comprised of rain-fed or surface water irrigated subsistence crops. Seasonal crop cover anomaly varied between -25% and 25% of the 13-year mean in these two regions. Predominantly climate-dependent region in central India showed high anomalies up to 200% of the 13-year crop cover mean, especially during winter season. Winter daytime mean temperature is overwhelmingly the most important climate variable for winter crops irrespective of the varied biophysical and socio

  20. Characterizing Impacts and Implications of Proposals for Solar Radiation Management, a Form of Climate Engineering

    Science.gov (United States)

    Ricke, Katharine L.

    Even under optimistic emissions scenarios, rising concentrations of greenhouse gases in the atmosphere will result in significant increases in global mean temperatures and associated effects for the foreseeable future (IPCC, 2007a,b). Concerns that mitigation may be too slow in coming have lead to renewed dialogue within the scientific community regarding potential strategies for counteracting global warming through geoengineering, defined as "the deliberate large-scale intervention in the Earth's climate system, in order to moderate global warming." (Shepherd et al., 2009) The geoengineering schemes that are considered most feasible today involve planetary albedo modification, or "solar radiation management" (SRM). This thesis addresses several outstanding questions regarding uncertainty in global and regional effects of SRM activities. The technical components of this work are centered on two modeling experiments which use a coupled atmosphere-ocean general circulation model (AOGCM) implemented through climate prediction.net. Drawing upon knowledge gained through these experiments and interaction with the broader research community, I explore the international relations implications of SRM and the global governance issues associated with it. The first experiment explored regional differences in climate modified by SRM using a large-ensemble modeling experiment that examines the effects of 54 global temperature stabilization scenarios. Our results confirm other research that shows a world with SRM would generally have less extreme temperature and precipitation anomalies than one with unmitigated greenhouse gas emissions and no SRM, but illustrate the physical unfeasibility of simultaneously stabilizing global precipitation and temperature as long as greenhouse gases continue to rise. Over time, simulated temperature and precipitation in large regions such as China and India vary significantly with different SRM trajectories and diverge from historic baselines in

    2007-07-01

    This paper examines the mutual implications between the climate change problem and the actual energy-at-a-crossroads situation of the unsustainable world energy model. The implications for the Spanish case are studied as a case example. The paper provides a brief review of the scientific evidence on climate change, analyzes the causes of the present energy dilemma and characterizes the problem to be addressed. The principal challenge for the future climate regime is to identify the nature and level of commitment that will provide sufficient incentives for all countries, with such a diversity of interests. The paper also exposes the most plausible framework for the future climate regime, the basic components of such a regime, the role to be played by the major stake holders and some guidelines for future negotiations.

    2012-09-01

    The purpose of this study is to explore the relationship between motives of smartphone use, social relation, and psychological well-being. The correlation analysis shows that the motives of smartphone use were positively related to bonding relations but negatively related to bridging relations. The hierarchical multiple regression analysis finds the associations among motives of smartphone use, social relations, perceived social support, and variables of psychological well-being. The results demonstrate that needs for caring for others were negatively related to loneliness and depression and positively related to self-esteem. However, the communication motives are not a significant predictor to determine self-esteem, loneliness, and depression. In addition, bonding and bridging social relations and social support significantly increase self-esteem and decrease loneliness and depression.

  3. On the climate change implications to water supply in the city of lima, Peru

    2009-04-01

    Water supply is one of the mayor problems that face the city of Lima in Peru. This problem is critic in periods of drought and extreme drought. Moreover, the hydrological cycle vulnerability to climate change, especially the impact on the availability of water resources requires the study and prediction of the consequences in water resources, among others. The project Liwa is a large-scale project that involves several disciplines addressing the problem of water supply in different perspectives in order to know the different parameters involved their interactions, their present and future implications, and at the end try to give an assessment and proposal for development and the optimal use of the water resource. By using hydrological models, the first part of the project addresses the water supply problem in Lima by considering the use of three basins that feed the city. Secondly, through numerical simulations it is determined the future potential of the system by taking account the potential impact of climate change on the hydrological cycle. A statistical downscaling scheme (Bárdossy 2002) will be used to generate time series of local climate scenarios. These results will be input to the hydrological models. In order to simulate discharges and storage volume in glaciers, reservoirs and water balance groundwater the conceptual model HBV (Bergström, 1995) will be used. The most important variables considered in the system are the rivers, melting glaciers, precipitation, groundwater availability and other elements of the hydrological cycle. Results show that climate change implies, as well known, mean temperature will rise gradually in the coming years. As a consequence of this phenomenon precipitation pattern in this area will decline in rainy years and will increase slightly in the drought years.

    The impact of climatic change can be on specific locations. However, the broader the affected area coverage, in mind, the higher would be the chance in missing critical details. In this light, this paper attempts to assess the possible climatic changes and their corresponding implications on agricultural production in northern Ethiopia. The analysis is based on the future (2030 and 2050) temperature and rainfall data, downscaled as ensemble of four general circulation models (GCMs) using the A2 and B1 emission scenarios for ten meteorological stations located in different agroecological zones of the study region. The result indicates that, based on emission scenarios, the mean maximum and minimum temperature would increase by 2-2.3 and 0.8-0.9 °C in 2030 and by 2.2-2.7 and 1.4-1.7 °C in 2050, respectively. This will be accompanied by an increase in the frequency of hot days and nights and a decrease in cool days and nights. While annual rainfall totals will remain unchanged, main rainy season ( kiremt) rainfall total would increase on average in 12.9 and 14.2 % under A2 and 9.5 and 11.2 % under B1 by 2030 and 2050, respectively. Owing to an increase in kiremt rainfall, the yield of maize and sorghum may increase at some sites under future climatic conditions, and the increase would be higher under CO2 fertilization. The results suggest the need for site-specific adaptation strategies to reduce the impact and/or exploit the opportunities of climate change.

    People with serious illness or disability are often burdened with social stigma that promotes a cycle of poverty via unemployment, inadequate housing and threats to mental health. Stigma may be conceptualized in terms of self-stigma (e.g., shame and lowered self-esteem) or public stigma (e.g., the general public's prejudice towards the stigmatized). This article examines two psychological processes that underlie public stigma: associative processes and rule-based processes. Associative proces...

  6. Types of Rural Extensionists' Expectations of Psychology and Their Implications on Psychologists' Practice.

    2016-12-01

    Psychology has great potential for contributing to rural development, particularly through supporting rural extension (RE). In this paper, the types of expectations extensionists have of psychology are identified, as well as possible ways of integrating psychosocial knowledge into the RE context. Rural extensionists from 12 Latin American countries were surveyed (n = 654). Of them, 89.4 % considered psychology could contribute to rural extension and commented on how this would be possible. Expectations were categorised and the nine mentioned by more than 20 % of them were utilized to conduct a two-steps cluster analysis. Three types of extensionists' expectations were identified: one wherein working with extensionists was highlighted; another characterised by a focus on working with farmers; and a third featuring a traditional, diffusionist extension approach, which views farmers as objects of psychologists' interventions. With the first type, psychologists should not neglect working with farmers and with the second, with extensionists. With the third type, reflecting on the expectations themselves and their underlying assumptions seems essential.

    This document contains the workshop proceedings on Climate Change in the Four Corners and Adjacent Regions: Implications for Environmental Restoration and Land-Use Planning which took place September 12-14, 1994 in Grand Junction, Colorado. The workshop addressed three ways we can use paleoenvironmental data to gain a better understanding of climate change and its effects. (1) To serve as a retrospective baseline for interpreting past and projecting future climate-induced environmental change, (2) To differentiate the influences of climate and humans on past environmental change, and (3) To improve ecosystem management and restoration practices in the future. The papers presented at this workshop contained information on the following subjects: Paleoclimatic data from the Pleistocene and Holocene epochs, climate change and past cultures, and ecological resources and environmental restoration. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

    To understand the psychological aspects in patients undergoing post-operative wound care and to gain insights for improving nursing practice. Very few studies have examined education on or practice of wound care with a view towards the patient's psychology. Descriptive exploratory qualitative study. Four patients who had undergone open surgery of the upper gastrointestinal tract were interviewed using a semi-structured format to gain an understanding of their feelings and opinions with regard to wound care. Interview transcripts were analysed using an inductive coding approach. Fifteen categories of responses were finally identified from the data. Patients wanted nursing staff to observe their wound more often so that patients could recognise improvement, to have better knowledge of the patient's disease and condition, to explain the patient's situation more completely and to appropriately answer questions. Patients also said that they felt more comfortable in posing questions or concerns regarding their condition to nursing staff than to their surgeons and did so while the wounds were being taken care of by nurses. These findings suggested the importance of nursing staff to fully understand and to be ready to share feelings regarding a patient's postoperative condition and to have skills in properly explaining the importance of each procedure or steps in treatments that a patient must undergo. The present study also indicates that it is imperative for nursing staff to learn methods to build relationships with patients so that they can express their feelings of fear or anxiety freely to nurses.

    Professional psychology faces an urgent crisis, which the following facts paint in stark relief. Adults over age 65 will rise to 20% of the U.S. population over the next 15 years and already account for a third of the country's health care expenditures. Up to 8 million older adults experience mental health and substance use conditions in a given year, yet most psychologists receive no training in their assessment and treatment. No more than an estimated 4%, or 3,000, psychologists nationwide specialize in geropsychology; a ratio approaching 3,000 to 1. A small group of advocates within the profession have sounded the alarm and worked to strengthen geropsychology as a specialty, but this has had very limited impact on the actual supply of psychologists qualified to provide services to this population. In 2012, an Institute of Medicine (IOM) committee released a report on the crisis regarding the mental health and substance use workforce for older adults. Drawing on that report, a team composed of geropsychologists, along with psychologists who served on the IOM committee, identifies in this article priority areas for workforce development. The authors assess the progress of psychology in each of these areas and offer a set of recommendations for future efforts by this profession to develop its own workforce and to strengthen the ability of other caregivers to address the behavioral health needs of older adults. Strengthening its own workforce and responding to the needs of this population is imperative if psychology is to maintain its relevance as a health profession and meet its ethical obligations to an increasingly diverse society.

    In the United States, one third of children and adolescents are overweight or obese, yet food and beverage companies continue to target them with advertising for products that contribute to this obesity crisis. When government restrictions on such advertising are proposed, the constitutional commercial speech doctrine is often invoked as a barrier to action. We explore incongruities between the legal justifications for the commercial speech doctrine and the psychological research on how food advertising affects young people. A proper interpretation of the First Amendment should leave room for regulations to protect young people from advertising featuring calorie-dense, nutrient-poor foods and beverages.

  13. Climate Change Driven Implications on Spatial Distribution of High Andean Peatlands in the Central Andes

    High Andean peatlands are among the most unique habitats in the tropical Andes and certainly among the least studied. High Andean peatlands occur patchily in montane grassland and scrub below snow line and above tree line. These high-elevation peatlands are sustained by glacial runoff and seasonal precipitation. We used remote sensing data to estimate that peatland habitat is approximately 2.5 % of our study region in the Puna, an ecoregion located in the high Andes above 4000 m a.s.l. Individual sizes of our estimated peatland polygons ranged from 0.72 ha to 1079 ha with a mean size of 4.9 ha. Climate change driven implications on spatial distribution of high Andean peatlands were assessed in two ways. First, we estimated the effect of predicted regional temperature increase by using the standard lapse rate of 2° C per 300 m for assessing peatland habitat patches that would remain above a critical thermocline. Nearly 80% of peatland habitat patches were predicted to occur below the thermocline if the prediction of 4° C temperature increase is realized. The second assessment relied on the quantified assumption that permanent snow or glacier cover, topographic characteristics (e.g. slope) and precipitation of a basin are essential variables in the occurrence of high Andean peatlands. All 17 basins were predicted to have a decrease in peatland habitat due to snow line uplift, decrease in precipitation and consequent insufficient wetland inflows. Total habitat loss was predicted for two basins in the semi-arid part of the study area with a snow line uplift to 5600 m and a projected decrease in precipitation of 1 mm per year over the next 40 years. A combined result of both assessments provides important information on climate change driven implications on the hydrology of high Andean peatlands and potential consequences for their spatial distribution within the Central Andes.

    Ecohydrological responses to climate change will exhibit spatial variability and understanding the spatial pattern of ecological impacts is critical from a land management perspective. To quantify climate change impacts on spatial patterns of ecohydrology across shrub steppe ecosystems in North America, we asked the following question: How will climate change impacts on ecohydrology differ in magnitude and variability across climatic gradients, among three big sagebrush ecosystems (SB-Shrubland, SB-Steppe, SB-Montane), and among Sage-grouse Management Zones? We explored these potential changes for mid-century for RCP8.5 using a process-based water balance model (SOILWAT) for 898 big sagebrush sites using site- and scenario-specific inputs. We summarize changes in available soil water (ASW) and dry days, as these ecohydrological variables may be helpful in guiding land management decisions about where to geographically concentrate climate change mitigation and adaptation resources. Our results suggest that during spring, soils will be wetter in the future across the western United States, while soils will be drier in the summer. The magnitude of those predictions differed depending on geographic position and the ecosystem in question: Larger increases in mean daily spring ASW were expected for high-elevation SB-Montane sites and the eastern and central portions of our study area. The largest decreases in mean daily summer ASW were projected for warm, dry, mid-elevation SB-Montane sites in the central and west-central portions of our study area (decreases of up to 50%). Consistent with declining summer ASW, the number of dry days was projected to increase rangewide, but particularly for SB-Montane and SB-Steppe sites in the eastern and northern regions. Collectively, these results suggest that most sites will be drier in the future during the summer, but changes were especially large for mid- to high-elevation sites in the northern half of our study area.

    Mobbing, or psychological harassment at the workplace, is usually defined as a situation in which a person or a group of people engage in extreme psychological violence against another person. In Spain, the number of reports for mobbing has increased extraordinarily in the last years. The reports are increasing dramatically not only before the Labour Courts, but also before the Civil Courts, with claims for damages, and before the Penal Court for offences causing physical or moral injury, etc., since at the present time this figure is not typified as an offence in the Spanish Penal Code. The high degree of complexity of this situation has given rise to frequent misuse of the term and to a number of false accusations of mobbing. A recent European Parliament Resolution on harassment at the workplace addressed the devastating consequences of false accusations. In this paper we present a case in which the "false" victim was mentally ill (paranoia) but succeed in generating an extreme dangerous environment of great harassment against the "false" assailants that were "falsely" accused of mobbing. Forensic diagnosis of the psychiatric disorder suffered by the "false" victim was essential to clarify the issue at the Penal Court.

    Before the Syrian uprising that began in 2011, the greater Fertile Crescent experienced the most severe drought in the instrumental record. For Syria, a country marked by poor governance and unsustainable agricultural and environmental policies, the drought had a catalytic effect, contributing to political unrest. We show that the recent decrease in Syrian precipitation is a combination of natural variability and a long-term drying trend, and the unusual severity of the observed drought is here shown to be highly unlikely without this trend. Precipitation changes in Syria are linked to rising mean sea-level pressure in the Eastern Mediterranean, which also shows a long-term trend. There has been also a long-term warming trend in the Eastern Mediterranean, adding to the drawdown of soil moisture. No natural cause is apparent for these trends, whereas the observed drying and warming are consistent with model studies of the response to increases in greenhouse gases. Furthermore, model studies show an increasingly drier and hotter future mean climate for the Eastern Mediterranean. Analyses of observations and model simulations indicate that a drought of the severity and duration of the recent Syrian drought, which is implicated in the current conflict, has become more than twice as likely as a consequence of human interference in the climate system.

  17. THE SOCIAL-ECONOMIC IMPLICATIONS OF THE CLIMATE CHANGES IN ROMANIA

    2005-12-01

    Full Text Available The social-economic implication of climatic changes in Romania are analysed under the following viewpoints: causes and effects; prevention and abatement; adjustment; institutional aspects of environmental management. The main reason of climatic changes is generated by the greenhouse effect (GE that determines the heating of the terrestrial surface, melt-down of icebergs, tornados, draughts and flooding more frequently and of increasing intensity. These extreme meteorological phenomena determine, over time, increasing human and material losses, which imposes measures with effects on short-, medium- and long-term for diminishing the greenhouse effect in accordance with the commitments and provisions of the Kyoto Protocol and the requirements for the sustainable development of the country. Proposals are made with respect to integrating environmental issues into economic and social development strategies, emphasising the need for increasing environment financing and attaching more importance to the Ministry of Environment which must couple its policy with the acquis communautaire and the EU programme for combating and preventing GE impact.

  18. Microbial ecology of mountain glacier ecosystems: biodiversity, ecological connections and implications of a warming climate.

    Glacier ecosystems are teeming with life on, beneath, and to a lesser degree, within their icy masses. This conclusion largely stems from polar research, with less attention paid to mountain glaciers that overlap environmentally and ecologically with their polar counterparts in some ways, but diverge in others. One difference lies in the susceptibility of mountain glaciers to the near-term threat of climate change, as they tend to be much smaller in both area and volume. Moreover, mountain glaciers are typically steeper, more dependent upon basal sliding for movement, and experience higher seasonal precipitation. Here, we provide a modern synthesis of the microbial ecology of mountain glacier ecosystems, and particularly those at low- to mid-latitudes. We focus on five ecological zones: the supraglacial surface, englacial interior, subglacial bedrock-ice interface, proglacial streams and glacier forefields. For each, we discuss the role of microbiota in biogeochemical cycling and outline ecological and hydrological connections among zones, underscoring the interconnected nature of these ecosystems. Collectively, we highlight the need to: better document the biodiversity and functional roles of mountain glacier microbiota; describe the ecological implications of rapid glacial retreat under climate change and resolve the relative contributions of ecological zones to broader ecosystem function. © 2017 The Authors.

    2009-07-01

    Climate variability and change is projected to have significant effects on the physical, chemical, and biological components of northern Canadian marine, terrestrial, and freshwater systems. As the climate continues to change, there will be consequences for biodiversity shifts and for the ranges and distribution of many species with resulting effects on availability, accessibility, and quality of resources upon which human populations rely. This will have implications for the protection and management of wildlife, fish, and fisheries resources; protected areas; and forests. The northward migration of species and the disruption and competition from invading species are already occurring and will continue to affect marine, terrestrial, and freshwater communities. Shifting environmental conditions will likely introduce new animal-transmitted diseases and redistribute some existing diseases, affecting key economic resources and some human populations. Stress on populations of iconic wildlife species, such as the polar bear, ringed seals, and whales, will continue as a result of changes in critical sea-ice habitat interactions. Where these stresses affect economically and culturally important species, they will have significant effects on people and regional economies. Further integrated, field-based monitoring and research programs, and the development of predictive models are required to allow for more detailed and comprehensive projections of change to be made, and to inform the development and implementation of appropriate adaptation, wildlife, and habitat conservation and protection strategies.

    To assess the status of the legal framework for air quality control in all countries of Latin America and Caribbean (LAC); to determine the current distribution of air monitoring stations and mean levels of air pollutants in all capital and large cities (more than 100 000 inhabitants); and to discuss the implications for climate change and public policymaking. From January 2015-February 2016, searches were conducted of online databases for legislation, regulations, policies, and air pollution programs, as well as for the distribution of monitoring stations and the mean annual levels of air pollution in all LAC countries. Only 117 cities distributed among 17 of 33 LAC countries had official information on ground level air pollutants, covering approximately 146 million inhabitants. The annual mean of inhalable particles concentration in most of the cities were over the World Health Organization Air Quality Guidelines; notably, only Bolivia, Peru, and Guatemala have actually adopted the guidelines. Most of the cities did not have information on particulate matter of 2.5 microns or less, and only a few measured black carbon. The air quality regulatory framework should be updated to reflect current knowledge on health effects. Monitoring and control of ground level pollutants should be extended and strengthened to increase awareness and protect public health. Using the co-benefits of air pollution control for health and climate as a framework for policy and decision-making in LAC is recommended.

    With the increasing concerns about global warming, Canada will have to deal with greenhouse gas emissions in the coming years. However, tackling climate change with public policy will affect Canada's economy. The aim of this paper is to explore the implications that a shift from oil and gas energy production to renewable energy would have on the economy. A review of the literature on employment in the energy sector was carried out for the purposes of the study. In the authors' view, this shift would not create that many jobs since employment in the unconventional oil and gas sectors in Canada is expected to grow and jobs in the renewable sector are not so different from those in traditional energy sectors. This paper highlighted the need for government and civil society to play strong roles in developing an energy policy which addresses global warming since the industries are focused on delivering outcomes they want, rather than on mitigating climate change.

    How plant populations, communities, and ecosystems respond to climate change is a critical focus in ecology today. The responses of introduced species may be especially rapid. Current models that incorporate temperature and precipitation suggest that future Bromus tectorum invasion risk is low for the Colorado Plateau. With a field warming experiment at two sites in southeastern Utah, we tested this prediction over 4 years, measuring B. tectorum phenology, biomass, and reproduction. In a complimentary greenhouse study, we assessed whether changes in field B. tectorum biomass and reproductive output influence offspring performance. We found that following a wet winter and early spring, the timing of spring growth initiation, flowering, and summer senescence all advanced in warmed plots at both field sites and the shift in phenology was progressively larger with greater warming. Earlier green-up and development was associated with increases in B. tectorum biomass and reproductive output, likely due early spring growth, when soil moisture was not limiting, and a lengthened growing season. Seeds collected from plants grown in warmed plots had higher biomass and germination rates and lower mortality than seeds from ambient plots. However, in the following two dry years, we observed no differences in phenology between warmed and ambient plots. In addition, warming had a generally negative effect on B. tectorum biomass and reproduction in dry years and this negative effect was significant in the plots that received the highest warming treatment. In contrast to models that predict negative responses of B. tectorum to warmer climate on the Colorado Plateau, the effects of warming were more nuanced, relied on background climate, and differed between the two field sites. Our results highlight the importance of considering the interacting effects of temperature, precipitation, and site-specific characteristics such as soil texture, on plant demography and have direct

    Full Text Available Large-scale deforestation may affect the surface energy budget and consequently climate by changing the physical properties of the land surface, namely biophysical effects. This study presents the potential energy budget change caused by deforestation in Northeastern China and its climate implications, which was evaluated by quantifying the differences in MODIS-observed surface physical properties between cropland and forest. We used the MODIS land products for the period of 2001–2010 in 112 cells of 0.75° × 0.75° each, within which only best quality satellite pixels over the pure forest and cropland pixels are selected for comparison. It is estimated that cropland has a winter (summer mean albedo of 0.38 (0.16, which is 0.15 (0.02 higher than that of forest. Due to the higher albedo, cropland absorbs 16.84 W∙m−2 (3.08 W∙m−2 less shortwave radiation than forest. Compared to forest, cropland also absorbs 8.79 W∙m−2 more longwave radiation in winter and 8.12 W∙m−2 less longwave radiation in summer. In total, the surface net radiation of cropland is 7.53 W∙m−2 (11.2 W∙m−2 less than that of forest in winter (summer. Along with these radiation changes, the latent heat flux through evapotranspiration over cropland is less than that over forest, especially in summer (−19.12 W∙m−2. Average sensible heat flux increases in summer (7.92 W∙m−2 and decreases in winter (−8.17 W∙m−2, suggesting that conversion of forest to cropland may lead to warming in summer and cooling in winter in Northeastern China. However, the annual net climate effect is not notable because of the opposite sign of the energy budget change in summer and winter.

    The magnitude and frequency of hydrometeorological extremes are expected to increase in the conterminous United States (CONUS) over the rest of this century, and their increase will significantly impact water resource management. In this study, we evaluated the large-scale climate change effects on extreme hydrological events and their implications for reservoir inflows in 138 headwater subbasins located upstream of reservoirs across CONUS using the Variable Infiltration Capacity (VIC) hydrologic model. The VIC model was forced with a 10-member ensemble of global circulation models under the Representative Concentration Pathway 8.5 that were dynamically downscaled using a regional climate model (RegCM4) and bias-corrected to 1/24° grid cell resolution. Four commonly used indices, including mean annual flow, annual center timing, 100-year daily high streamflow, and 10-year 7-day average low streamflow were used for evaluation. The results projected an increase in the high streamflow by 44% for a majority of subbasins upstream of flood control reservoirs in the central United States (US) and a decrease in the low streamflow by 11% for subbasins upstream of hydropower reservoirs across the western US. In the eastern US, frequencies of both high and low streamflow were projected to increase in the majority of subbasins upstream of both hydropower and flood control reservoirs. Increased frequencies of both high and low streamflow events can potentially make reservoirs across CONUS more vulnerable to future climate conditions. This study estimates reservoir inflow changes over the next several decades, which can be used to optimize water supply management downstream.

    We review findings from laboratory research on age differences in the effects of emotion on cognition. Particular attention is given to sadness leading to mood congruent memory and to anxiety leading to selective attention bias to threat. While older adults in normal moods show the positivity effect as expected from socio-emotional selectivity theory, older adults whose mood has changed from baseline to sad or anxious show these mood-related cognitive biases. These mood-related biases are a foundational part of the theory underlying cognitive behavior therapy (CBT) and so these laboratory findings suggest ways that CBT may work differently with older adults. Pilot work suggests that the presence or absence of these effects may also predict responsiveness to treatment using CBT. © 2015 The Institute of Psychology, Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

  12. The epistemology of climate models and some of its implications for climate science and the philosophy of science

    Science.gov (United States)

    Katzav, Joel

    2014-05-01

    I bring out the limitations of four important views of what the target of useful climate model assessment is. Three of these views are drawn from philosophy. They include the views of Elisabeth Lloyd and Wendy Parker, and an application of Bayesian confirmation theory. The fourth view I criticise is based on the actual practice of climate model assessment. In bringing out the limitations of these four views, I argue that an approach to climate model assessment that neither demands too much of such assessment nor threatens to be unreliable will, in typical cases, have to aim at something other than the confirmation of claims about how the climate system actually is. This means, I suggest, that the Intergovernmental Panel on Climate Change's (IPCC's) focus on establishing confidence in climate model explanations and predictions is misguided. So too, it means that standard epistemologies of science with pretensions to generality, e.g., Bayesian epistemologies, fail to illuminate the assessment of climate models. I go on to outline a view that neither demands too much nor threatens to be unreliable, a view according to which useful climate model assessment typically aims to show that certain climatic scenarios are real possibilities and, when the scenarios are determined to be real possibilities, partially to determine how remote they are.

  14. Climate Change: Implications for the Assumptions, Goals and Methods of Urban Environmental Planning

    Directory of Open Access Journals (Sweden)

    Kristina Hill

    2016-12-01

    Full Text Available As a result of increasing awareness of the implications of global climate change, shifts are becoming necessary and apparent in the assumptions, concepts, goals and methods of urban environmental planning. This review will present the argument that these changes represent a genuine paradigm shift in urban environmental planning. Reflection and action to develop this paradigm shift is critical now and in the next decades, because environmental planning for cities will only become more urgent as we enter a new climate period. The concepts, methods and assumptions that urban environmental planners have relied on in previous decades to protect people, ecosystems and physical structures are inadequate if they do not explicitly account for a rapidly changing regional climate context, specifically from a hydrological and ecological perspective. The over-arching concept of spatial suitability that guided planning in most of the 20th century has already given way to concepts that address sustainability, recognizing the importance of temporality. Quite rapidly, the concept of sustainability has been replaced in many planning contexts by the priority of establishing resilience in the face of extreme disturbance events. Now even this concept of resilience is being incorporated into a novel concept of urban planning as a process of adaptation to permanent, incremental environmental changes. This adaptation concept recognizes the necessity for continued resilience to extreme events, while acknowledging that permanent changes are also occurring as a result of trends that have a clear direction over time, such as rising sea levels. Similarly, the methods of urban environmental planning have relied on statistical data about hydrological and ecological systems that will not adequately describe these systems under a new climate regime. These methods are beginning to be replaced by methods that make use of early warning systems for regime shifts, and process

  15. The Ethics of Belief, Cognition, and Climate Change Pseudoskepticism: Implications for Public Discourse.

    The relationship between knowledge, belief, and ethics is an inaugural theme in philosophy; more recently, under the title "ethics of belief" philosophers have worked to develop the appropriate methodology for studying the nexus of epistemology, ethics, and psychology. The title "ethics of belief" comes from a 19th-century paper written by British philosopher and mathematician W.K. Clifford. Clifford argues that we are morally responsible for our beliefs because (a) each belief that we form creates the cognitive circumstances for related beliefs to follow, and (b) we inevitably influence each other through those beliefs. This study argues that recent cognitive research supports Cliffordian insights regarding patterns of belief formation and social influence. From the confirmation offered by such research, it follows that informational accuracy holds serious ethical significance in public discourse. Although scientific and epistemological matters are not always thought to be linked to normative morality, this study builds on Clifford's initial insights to show their linkage is fundamental to inquiry itself. In turn, Clifford's ethical and epistemic outline can inform a framework grounded in "public reason" under which seemingly opposed science communication strategies (e.g., "information deficit" and "cultural cognition" models) are philosophically united. With public discourse on climate change as the key example, empirically informed and grounded strategies for science communication in the public sphere are considered.

    There is considerable interest in factors controlling “warm-edge” limits – the lower elevation and latitudinal edges of a species' range. Understanding whether conservation measures can mitigate anticipated change in climate requires consideration of future climate as well as species interactions.

    Full Text Available Background and Aim: Identifying factors associated with employees empowerment of their working centers can promote organizational performance of hospitals. The current study aimed at investigating the relationship of both organizational climate and organizational silence with psychological empowerment in the public hospitals affiliated with Birjand University of Medical Sciences (BUMS. Materials and Methods: This cross-sectional and correlational study was carried out in 2015. Using a stratified randomized sampling, 400 employees were selected from the public. hospitals affiliated with BUMS.  Data collection tools were. three self-administered questionnaires including organizational climate, organizational silence, and psychological empowerment. . Validity and reliability of the questionnaires were verified using experts judgment and Cronbach alpha coefficients more than 0.7, respectively. Data analysis was done by means of SPSS (V: 18 software using one sample t test, independent t test, Pearson correlation coefficient, and one-way ANOVA. The cut-off point of 70%.of Likert-type scale (3.5 was considered as an acceptable mean for each variable. Results: The mean organizational climate and organizational silence was 2.45 and 3.18, respectively which did not correspond with an acceptable mean (P<0.05. Although the mean psychological construct which was 3.6 had an acceptable value, mean of the two other sub-variables i.e. “trust to others” and “self-determination” were 3.2±0.83 and 3.42±0.67, respectively; and they were not at an acceptable level (P<0.05. It is observed that both organizational climate and organizational silence were positively correlated to psychological empowerment with 0.6 and 0.58 coefficients, respectively (P<0.05. Conclusion:  It is suggested that the hospitals administrators should promote the psychological empowerment of their employees  through improving organizational climate and decreasing organizational

    The aim of this study was to test the mediating role of the satisfaction of dental students' basic psychological needs of autonomy, competence and relatedness on the association between learning climate, feedback and student motivation. The latter was based on the self-determination theory's concepts of differentiation of autonomous motivation, controlled motivation and amotivation. A cross-sectional correlational study was conducted where 924 students completed self-reported questionnaires measuring motivation, perception of the learning climate, feedback and basic psychological needs satisfaction. Descriptive statistics, Cronbach's alpha scores and bivariate correlations were computed. Mediation of basic needs on each predictor-outcome association was tested based on a series of regression analyses. Finally, all variables were integrated into one structural equation model, controlling for the effects of age, gender and year of study. Cronbach's alpha scores were acceptable (.655 to .905). Correlation analyses showed positive and significant associations between both an autonomy-supportive learning climate and the quantity and quality of feedback received, and students' autonomous motivation, which decreased and became negative when correlated with controlled motivation and amotivation, respectively. Regression analyses revealed that these associations were indirect and mediated by how these predictors satisfied students' basic psychological needs. These results were corroborated by the structural equation analysis, in which data fit the model well and regression paths were in the expected direction. An autonomy-supportive learning climate and the quantity and quality of feedback were positive predictors of students' autonomous motivation and negative predictors of amotivation. However, this was an indirect association mediated by the satisfaction of students' basic psychological needs. Consequently, supporting students' needs of autonomy, competence and

    The empirical base suggesting a link between prenatal maternal anxiety, stress or depression and cognitive, behavioral, and biological outcomes in the infant and child has increased dramatically in the past 10 years. In this review, we consider the relevance of prenatal maternal mood for child mental health practitioners; the empirical base for a likely causal impact of the link between prenatal anxiety, depression, or stress and child outcomes; the degree to which the available evidence is sufficient for informing or altering clinical practice; and the possible role of prenatal interventions for promoting child health and development. A selective review of PubMed, Cochrane Library and other sources was undertaken. Clinically significant links between maternal prenatal distress and child behavioral and cognitive outcomes have been reported; predictions to stress physiology, immunology, and neurodevelopment have been reported but the effect sizes and clinical significance is less clear. Several candidate mechanisms have been proposed, with some supporting evidence. Many behavioral treatments for prenatal maternal distress exist, but their application to promoting child health is largely unknown. Research on maternal prenatal distress is a good example of translational research and offers a strong paradigm for promoting interdisciplinary clinical research on child health and development. © 2013 The Authors.

    2013-09-01

    Synthesizing the interdisciplinary literature, we characterize color-blind racial ideology (CBRI) as consisting of two interrelated domains: color-evasion (i.e., denial of racial differences by emphasizing sameness) and power-evasion (i.e., denial of racism by emphasizing equal opportunities). Mounting empirical data suggest that the color-evasion dimension is ineffective and in fact promotes interracial tension and potential inequality. CBRI may be conceived as an ultramodern or contemporary form of racism and a legitimizing ideology used to justify the racial status quo. Four types of CBRI are described: denial of (a) race, (b) blatant racial issues, (c) institutional racism, and (d) White privilege. We discuss empirical findings suggesting a relationship between CBRI and increased racial prejudice, racial anger, and racial fear. Implications for education, training, and research are provided. © 2013 APA, all rights reserved.

  2. An exploration of the hypothesis that testosterone is implicated in the psychological functioning of women with polycystic ovary syndrome (PCOS).

    One of the diagnostic features of polycystic ovary syndrome (PCOS) is elevation of the androgen, testosterone. It is known that women with PCOS are more likely to suffer from psychological problems, especially anxiety and depression, than other women. However, little is known of how much of this is due to testosterone, and if so, what the mechanism(s) might be. This study explores the hypothesis that testosterone impacts women with PCOS both directly and indirectly, via testosterone currently in the bloodstream and through prenatal exposure. It is hypothesised that direct effects occur when testosterone acts directly upon receptors; indirect effects occur where the impact of testosterone is mediated via another variable; activational effects are ephemeral and are caused by testosterone in the bloodstream; organizational effects occur prenatally and cause permanent changes. Four pathways are hypothesised in this paper: 1/ a direct and activational pathway which improves mental rotation ability; 2/ an indirect and activational pathway, whereby distress is caused when the physiological symptoms of testosterone are experienced as embarrassing or otherwise disturbing; 3/ an indirect and organizational effect on mood, where elevated prenatal testosterone predisposes women with PCOS to low blood sugar levels and thus low mood; 4/ and finally, it is suggested that the pathway from biology to psychology can be travelled in reverse, with a direct activational effect of relaxation training on the reduction of adrenal androgens. Testing these hypotheses has important implications for our understanding of PCOS, and our ability to treat this condition more effectively. Copyright © 2017. Published by Elsevier Ltd.

  3. Is psychological membership in the classroom a function of standing out while fitting in? Implications for achievement motivation and emotions.

    2017-04-01

    Education researchers have consistently linked students' perceptions of "fitting in" at school with patterns of motivation and positive emotions. This study proposes that "standing out" is also helpful for producing these outcomes, and that standing out works in concert with perceptions of fitting in. In a sample of 702 high school students nested within 33 classrooms, principal components analysis and confirmatory factor analysis were each conducted on half of the sample. Results support the proposed structure of measures of standing out and fitting in. Multilevel latent profile analysis was then used to classify students into four profiles of standing out while fitting in (SOFI): Unfulfilled, Somewhat Fulfilled, Nearly Fulfilled, and Fulfilled. A multinomial logistic regression revealed that students of color and those on who paid free/reduced prices lunch were overrepresented in the Unfulfilled and Somewhat Fulfilled profiles. A multilevel path analysis was then performed to assess the direct and indirect associations of profile membership with measures of task value and achievement emotions. Relative to the other profiles, students in the Fulfilled SOFI Profile express greater psychological membership in their classrooms and, in turn, express higher valuing of academic material (i.e., intrinsic value, utility value, and attainment value) and more positive achievement emotions (i.e., more enjoyment and pride; less boredom, hopelessness, and shame). This investigation provides critical insights on the potential benefits of structuring academic learning environments to foster feelings of distinctiveness among adolescents; and has implications for cultivating identities and achievement motivation in academic settings.

    Future changes in storm characteristics and storm tracks over the eastern North Atlantic may have profound implications for energy providers, coastal communities and water resources availability across the European sector. Shifts in the storm tracks and the amount and intensity of precipitation are of particular concern to local/ municipal governments as they contemplate climate change adaptation/ mitigation strategies. Communicating the latest science to these end users is a two-pronged problem. On one prong the scientific community still has some way to go before fully understanding the physical mechanisms driving projected changes at local to regional scales and their associated uncertainties (which can be quite large). On the other prong planners require up-to-date, reliable information at just these scales as they seek to make decisions, which will resonate for decades. The present study investigates projected changes to storms and precipitation over Northern Europe and decomposes the sources of uncertainty surrounding these changes. Strategies for communicating these changes and uncertainties with planners are also discussed. The city of Bergen, which is a participant in the ECLISE project, is employed as a case study for how complex and often counterintuitive climate information can be made useful for end users. Some large-scale, robust changes in storm track statistics have been identified in the ensemble mean climate change response. However, there are often widely varying responses between models and little analysis on the role intra-model variability. A focus on the multi model ensemble mean response is useful in that it isolates externally forced (i.e. climate change) aspects of future variability. However, this approach underestimates the influence of internal variability (weather-related "noise") and its contribution to total uncertainty. Recent research suggests that internal variability can make a large contribution to overall uncertainty with clear

  5. CO2 Capture from the Air: Technology Assessment and Implications for Climate Policy

    2002-05-01

    It is physically possible to capture CO2 directly from the air and immobilize it in geological structures. Today, there are no large-scale technologies that achieve air capture at reasonable cost. Yet, strong arguments suggest that it will comparatively easy to develop practical air capture technologies on the timescales relevant to climate policy [1]. This paper first analyzes the cost of air capture and then assesses the implications for climate policy. We first analyze the lower bound on the cost needed for air capture, describing the thermodynamic and physical limits to the use of energy and land. We then compare the costs of air capture to the cost of capture from combustion exhaust streams. While the intrinsic minimum energy requirement is larger for air capture, we argue that air capture has important structural advantages, such as the reduction of transport costs and the larger potential for economies of scale. These advantages suggest that, in the long-run air capture be competitive with other methods of achieving deep emissions reductions. We provide a preliminary engineering-economic analysis of an air capture system based on CaO to CaCO3 chemical looping [1]. We analyze the possibility of doing the calcination in a modified pressurized fluidized bed combustor (PFBC) burning coal in a CO2 rich atmosphere with oxygen supplied by an air separation unit. The CaCO3-to-coal ratio would be ~2:1 and the system would be nearly thermally neutral. PFBC systems have been demonstrated at capacities of over 100 MW. Such systems already include CaCO3 injection for sulfur control, and operate at suitable temperatures and pressures for calcination. We assess the potential to recover heat from the dissolution of CaO in order to reduce the overall energy requirements. We analyze the possibility of adapting existing large water/air heat exchangers for use as contacting systems to capture CO2 from the air using the calcium hydroxide solution.

    2015-02-01

    Climate scientists have concluded that stratospheric ozone depletion has been a major driver of Southern Hemisphere climate processes since about 1980. The implications of these observed and modelled changes in climate are likely to be far more pervasive for both terrestrial and marine ecosystems than the increase in ultraviolet-B radiation due to ozone depletion; however, they have been largely overlooked in the biological literature. Here, we synthesize the current understanding of how ozone depletion has impacted Southern Hemisphere climate and highlight the relatively few documented impacts on terrestrial and marine ecosystems. Reviewing the climate literature, we present examples of how ozone depletion changes atmospheric and oceanic circulation, with an emphasis on how these alterations in the physical climate system affect Southern Hemisphere weather, especially over the summer season (December-February). These potentially include increased incidence of extreme events, resulting in costly floods, drought, wildfires and serious environmental damage. The ecosystem impacts documented so far include changes to growth rates of South American and New Zealand trees, decreased growth of Antarctic mosses and changing biodiversity in Antarctic lakes. The objective of this synthesis was to stimulate the ecological community to look beyond ultraviolet-B radiation when considering the impacts of ozone depletion. Such widespread changes in Southern Hemisphere climate are likely to have had as much or more impact on natural ecosystems and food production over the past few decades, than the increased ultraviolet radiation due to ozone depletion. © 2014 John Wiley & Sons Ltd.

    Nitrogen is a major nutrient for all life on Earth and could plausibly play a similar role in extraterrestrial biospheres. The major reservoir of nitrogen at Earth's surface is atmospheric N2, but recent studies have proposed that the size of this reservoir may have fluctuated significantly over the course of Earth's history with particularly low levels in the Neoarchean - presumably as a result of biological activity. We used a biogeochemical box model to test which conditions are necessary to cause large swings in atmospheric N2 pressure. Parameters for our model are constrained by observations of modern Earth and reconstructions of biomass burial and oxidative weathering in deep time. A 1-D climate model was used to model potential effects on atmospheric climate. In a second set of tests, we perturbed our box model to investigate which parameters have the greatest impact on the evolution of atmospheric pN2 and consider possible implications for nitrogen cycling on other planets. Our results suggest that (a) a high rate of biomass burial would have been needed in the Archean to draw down atmospheric pN2 to less than half modern levels, (b) the resulting effect on temperature could probably have been compensated by increasing solar luminosity and a mild increase in pCO2, and (c) atmospheric oxygenation could have initiated a stepwise pN2 rebound through oxidative weathering. In general, life appears to be necessary for significant atmospheric pN2 swings on Earth-like planets. Our results further support the idea that an exoplanetary atmosphere rich in both N2 and O2 is a signature of an oxygen-producing biosphere.

    Organic aerosol (OA) constitutes a dominant fraction of airborne particulates over Indo-Gangetic Plain (IGP) especially during post-monsoon and winter. Its exposure has been associated with adverse health effects while there are evidences of its interference with Earth's radiation balance and cloud condensation (CC), resulting possible alteration of hydrological cycle. Therefore, presence and effects of OA directly link it with food security and thereby, sustainability issues. In these contexts, atmospheric chemistry involving formation, volatility and aging of primary OA (POA) and secondary OA (SOA) have been reviewed with specific reference to IGP. Systematic reviews on science of OA sources, evolution and climate perturbations are presented with databases collected from 82 publications available throughout IGP till 2016. Both gaseous and aqueous phase chemical reactions were studied in terms of their potential to form SOA. Efforts were made to recognize the regional variation of OA, its chemical constituents and sources throughout IGP and inferences were made on its possible impacts on regional air quality. Mass fractions of OA to airborne particulate showed spatial variation likewise in Lahore (37 and 44% in fine and coarse fractions, respectively), Patiala (28 and 37%), Delhi (25 and 38%), Kanpur (24 and 30%), Kolkata (11 and 21%) and Dhaka. Source apportionment studies indicate biomass burning, coal combustion and vehicular emissions as predominant OA sources. However, sources represent considerable seasonal variations with dominance of gasoline and diesel emissions during summer and coal and biomass based emissions during winter and post-monsoon. Crop residue burning over upper-IGP was also frequently held responsible for massive OA emission, mostly characterized by its hygroscopic nature, thus having potential to act as CC nuclei. Conclusively, climatic implication of particulate bound OA has been discussed in terms of its interaction with radiation balance.

    We synthesized an expert review of climate change implications for hydroecological and terrestrial ecological systems in the northern coastal temperate rainforest of North America. Our synthesis is based on an analysis of projected temperature, precipitation, and snowfall stratified by eight biogeoclimatic provinces and three vegetation zones. Five IPCC CMIP5 global climate models (GCMs) and two representative concentration pathways (RCPs) are the basis for projections of mean annual temperature increasing from a current average (1961–1990) of 3.2 °C to 4.9–6.9 °C (5 GCM range; RCP4.5 scenario) or 6.4–8.7 °C (RCP8.5), mean annual precipitation increasing from 3130 mm to 3210–3400 mm (3–9 % increase) or 3320–3690 mm (6–18 % increase), and total precipitation as snow decreasing from 1200 mm to 940–720 mm (22–40 % decrease) or 720–500 mm (40–58 % decrease) by the 2080s (2071–2100; 30-year normal period). These projected changes are anticipated to result in a cascade of ecosystem-level effects including: increased frequency of flooding and rain-on-snow events; an elevated snowline and reduced snowpack; changes in the timing and magnitude of stream flow, freshwater thermal regimes, and riverine nutrient exports; shrinking alpine habitats; altitudinal and latitudinal expansion of lowland and subalpine forest types; shifts in suitable habitat boundaries for vegetation and wildlife communities; adverse effects on species with rare ecological niches or limited dispersibility; and shifts in anadromous salmon distribution and productivity. Our collaborative synthesis of potential impacts highlights the coupling of social and ecological systems that characterize the region as well as a number of major information gaps to help guide assessments of future conditions and adaptive capacity.

    Posttraumatic stress disorder (PTSD) and other psychopathological outcomes have not been sufficiently studied in community-based samples in Latin America. This study explored various psychopathological reactions and their respective risk factors two months after Hurricane Mitch struck Honduras in October 1998. In the Honduran capital of Tegucigalpa, 800 respondents age 15 and older were selected from residential areas of high, middle, or low socioeconomic status that had suffered either high or low impact from the devastating effects of the hurricane. The Composite International Diagnostic Interview was used to diagnose PTSD. Depression, alcohol misuse, and grief reaction were examined using screening instruments, and the Self-Reporting Questionnaire was used to measure demoralization. The Impact of Event Scale was administered to ascertain the severity of the posttraumatic reaction. PTSD was present in 10.6% of the sample. Respondents from the high-impact residential areas were more distressed, had higher scores on the grief inventory, and showed greater severity in PTSD symptoms. The respondents from the high-impact residential areas also had higher prevalence rates of major depression, alcoholism, and prior emotional problems. The best explanatory model for the risk of developing PTSD included the degree of exposure based on reported traumatic events, and associated increased demoralization. Among the persons with PTSD, its severity was predicted by being female and by the degree of exposure to hurricane-related traumatic events. Out of a total population of 3.3 million adults (age 15 and older) in Honduras, it is estimated that over 492,000 of them may have developed PTSD due to Hurricane Mitch. Adequate health disaster preparedness and response requires full acknowledgement of the multiple psychological effects that victims experience.

    Full Text Available Introduction: To investigate relationships between ambient temperatures and violent crimes to determine whether those relationships are consistent across different crime categories and whether they are best described as increasing linear functions, or as curvilinear functions that decrease beyond some temperature threshold. A secondary objective was to consider the implications of the observed relationships for injuries and deaths from violent crimes in the context of a warming climate. To address these questions, we examined the relationship between daily ambient temperatures and daily incidents of violent crime in Dallas, Texas from 1993–1999.Methods: We analyzed the relationships between daily fluctuations in ambient temperature, other meteorological and temporal variables, and rates of daily violent crime using time series piece-wise regression and plots of daily data. Violent crimes, including aggravated assault, homicide, and sexualassault, were analyzed.Results: We found that daily mean ambient temperature is related in a curvilinear fashion to daily rates of violent crime with a positive and increasing relationship between temperature and aggravated crime that moderates beyond temperatures of 80 F and then turns negative beyond 90 F.Conclusion: While some have characterized the relationship between temperature and violent crime as a continually increasing linear function, leaving open the possibility that aggravated crime will increase in a warmer climate, we conclude that the relationship in Dallas is not linear, but moderatesand turns negative at high ambient temperatures. We posit that higher temperatures may encourage people to seek shelter in cooler indoor spaces, and that street crime and other crimes of opportunity are subsequently decreased. This finding suggests that the higher ambient temperatures expected with climate change may result in marginal shifts in violent crime in the short term, but are not likely to be

  15. Comparison of the observed and calculated clear sky greenhouse effect - Implications for climate studies

    The clear sky greenhouse effect is defined in terms of the outgoing longwave clear sky flux at the top of the atmosphere. Recently, interest in the magnitude of the clear sky greenhouse effect has increased due to the archiving of the clear sky flux quantity through the Earth Radiation Budget Experiment (ERBE). The present study investigates to what degree of accuracy this flux can be analyzed by using independent atmospheric and surface data in conjunction with a detailed longwave radiation model. The conclusion from this comparison is that for most regions over oceans the analyzed fluxes agree to within the accuracy of the ERBE-retrieved fluxes (+/- 5 W/sq m). However, in regions where deep convective activity occurs, the ERBE fluxes are significantly higher (10-15 W/sq m) than the calculated fluxes. This bias can arise from either cloud contamination problems or variability in water vapor amount. It is argued that the use of analyzed fluxes may provide a more consistent clear sky flux data set for general circulation modeling validation. Climate implications from the analyzed fluxes are explored. Finally, results for obtaining longwave surface fluxes over the oceans are presented.

    This paper summarizes a number of studies examining potential economic impacts of global climate change policies. Implications for the United States as a whole, the U.S. energy sector, the U.S. economy, businesses and consumers, and world economies are considered. Impact assessments are performed of U.S. carbon emissions, carbon taxes, and carbon restrictions by comparing estimates from various organizations. The following conclusions were made from the economic studies: (1) the economic cost of carbon abatement is expensive; (2) the cost of unilateral action is very expensive with little quantifiable evidence that global emissions are reduced; (3) multilateral actions of developed countries are also very expensive, but there is quantifiable evidence of global emissions reductions; and (4) global actions have only been theoretically addressed. Paralleling these findings, the energy analyses show that the U.S. is technologically unprepared to give up fossil fuels. As a result: (1) carbon is not stabilized without a high tax, (2) stabilization of carbon is elusive, (3) technology is the only long-term answer, and (4) targeted programs may be appropriate to force technology development. 8 tabs.

    Climate change is supposed to have influences on water quality and ecosystem. However, only few studies have assessed the effect of climate change on environmental toxic contaminants in urban lakes. In this research, response of several toxic contaminants in twelve urban lakes in Beijing, China, to the seasonal variations in climatic factors was studied. Fluorides, volatile phenols, arsenic, selenium, and other water quality parameters were analyzed monthly from 2009 to 2012. Multivariate statistical methods including principle component analysis, cluster analysis, and multiple regression analysis were performed to study the relationship between contaminants and climatic factors including temperature, precipitation, wind speed, and sunshine duration. Fluoride and arsenic concentrations in most urban lakes exhibited a significant positive correlation with temperature/precipitation, which is mainly caused by rainfall induced diffuse pollution. A negative correlation was observed between volatile phenols and temperature/precipitation, and this could be explained by their enhanced volatilization and biodegradation rates caused by higher temperature. Selenium did not show a significant response to climatic factor variations, which was attributed to low selenium contents in the lakes and soils. Moreover, the response degrees of contaminants to climatic variations differ among lakes with different contamination levels. On average, temperature/precipitation contributed to 8%, 15%, and 12% of the variations in volatile phenols, arsenic, and fluorides, respectively. Beijing is undergoing increased temperature and heavy rainfall frequency during the past five decades. This study suggests that water quality related to fluoride and arsenic concentrations of most urban lakes in Beijing is becoming worse under this climate change trend. Copyright © 2014.

    The formation and maintenance of young adult romantic relationships that are free from violence and are characterized by love, connection, and effective problem-solving have important implications for later well-being and family functioning. In this study, we examined adolescent hostile-aggressive behavior (HAB) and family relationship quality as key individual and family-level factors that may forecast later romantic relationship functioning. Guided by a family systems framework, we evaluated the reciprocal influences of adolescent hostility and family climate, to provide a more comprehensive picture of the etiology of romantic relationship functioning. We drew on a large sample (N = 974) of young adults (mean age = 19.5) that were followed starting in the fall of 6th Grade, and subsequently in spring of 6th, 7th, 8th, 9th, and 10th grades prior to the young adult assessment. Using a Latent Difference Score cross-lag model (McArdle, 2009), our results indicated that a more positive family climate was associated with decreases in HAB, but HAB was not associated with changes in family climate. Further, the influence of the family climate on HAB was consistent across all time points. HAB and family climate had different predictions for young adult romantic relationships: increasing HAB over adolescence predicted relationship violence, while maintenance in family climate was a key predictor of relationship problem-solving skills. The only predictor of love and connection in relationships was early family functioning. Implications for developmental theory and prevention science are discussed. PMID:27337516

  1. Potential Effects of Drought on Tree Dieback in Great Britain and Implications for Forest Management in Adaptation to Climate Change

    2017-04-01

    The drought and heat stress has alerted the composition, structure and biogeography of forests globally, whilst the projected severe and widespread droughts are potentially increasing. This challenges the sustainable forest management to better cope with future climate and maintain the forest ecosystem functions and services. Many studies have investigated the climate change impacts on forest ecosystem but less considered the climate extremes like drought. In this study, we implement a dynamic ecosystem model based on a version of LPJ-GUESS parameterized with European tree species and apply to Great Britain at a finer spatial resolution of 5*5 km. The model runs for the baseline from 1961 to 2011 and projects to the latter 21st century using 100 climate scenarios generated from MaRIUS project to tackle the climate model uncertainty. We will show the potential impacts of climate change on forest ecosystem and vegetation transition in Great Britain by comparing the modelled conditions in the 2030s and the 2080s relative to the baseline. In particular, by analyzing the modelled tree mortality, we will show the tree dieback patterns in response to drought for various species, and assess their drought vulnerability across Great Britain. We also use species distribution modelling to project the suitable climate space for selected tree species using the same climate scenarios. Aided by these two modelling approaches and based on the corresponding modelling results, we will discuss the implications for adaptation strategy for forest management, especially in extreme drought conditions. The gained knowledge and lessons for Great Britain are considered to be transferable in many other regions.

  6. Seasonality of Climate Drives the Number of Tree Hollows in Eastern Australia: Implications of a Changing Climate

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Tree hollow number is investigated across an altitudinal and climatic gradient in eastern Australia. The relationship between seasonal climate and local site factors to hollow number at a regional scale was investigated. Moisture retention, rainfall, and solar radiation during the summer period were the highest contributing factors to hollow number in the model presented. The relationship of hollow number with the significant variables was unimodal in nature with either extreme causing a decline within the region. The results indicate that increased seasonality of rainfall, solar radiation, and temperatures as predicted by anthropogenic climate change will cause a shift in the optimal location for hollow number. Change in tree hollows is reliant on taxonomic replacement through dispersal and establishment and subsequently time to allow individuals to mature. The reduction in this resource stimulated by changes in seasonality predicted within the ensuing decades is likely to cause a loss of hollows across the landscape with the resource not being replaced for hundreds of years. The number of hollows within a landscape may drastically reduce due to climate change alone irrespective of tree clearing rates.

    Numerous studies have documented instantaneous reductions in albedo (darkening) of the land surface after fires in sub-Saharan Africa. However, at longer time scales the interplay of vegetation removal and revelation of dry underlaying soils could result in higher albedo (brightening) and a negative radiative forcing, a phenomenon that requires further investigation. In this study we consider the effect of fire on albedo weeks to months after early fires occurring southern Africa at the onset of the 2015 dry season. We make opportunistic use of the SMAP radar-based soil moisture product to account and correct for fine-scale spatiotemporal variability in soil moisture. Furthermore, this allows us to bypass issues associated with reference pixel approach. We use advanced statistical modeling and multiple satellite data sources to quantify the relative contributions of underlying soil type, fire-induced char deposition and vegetation removal, and seasonal fluctuations in soil moisture to overall albedo dynamics. In line with previous studies, we find a general decrease in albedo immediately following fire. However, within a month of burning, about half of the study pixels exhibit fire-induced brightening. Long-lived albedo increases of up to 0.04 are common in semiarid regions. These values continue to increase over the course of the dry season. There are distinct geographic trends in the occurrence of brightening which are attributable to regional gradients in soil type and vegetation cover. Given the prevalence of brightening in drier regions and the potential for persistent surface modification, we discuss the implications for regional climate. Specifically, we consider how bright burn scars following widespread fires offer a mechanism that could help explain recent evidence of fire-induced rainfall suppression in African drylands.

    Development efforts for poverty reduction and food security in sub-Saharan Africa will have to consider future climate change impacts. Large uncertainties in climate change impact assessments do not necessarily complicate, but can inform development strategies. The design of development strategies will need to consider the likelihood, strength, and interaction of climate change impacts across biosphere properties. We here explore the spread of climate change impact projections and develop a composite impact measure to identify hotspots of climate change impacts, addressing likelihood and strength of impacts. Overlapping impacts in different biosphere properties (e.g. flooding, yields) will not only claim additional capacity to respond, but will also narrow the options to respond and develop. Regions with severest projected climate change impacts often coincide with regions of high population density and poverty rates. Science and policy need to propose ways of preparing these areas for development under climate change impacts. © 2014 John Wiley & Sons Ltd.

    Assessing potential future changes in arctic and boreal plant species productivity, ecosystem composition, and canopy complexity is essential for understanding environmental responses under expected altered climate forcing. We examined potential changes in the dominant plant functional types (PFTs) of the sedge tundra, shrub tundra, and boreal forest ecosystems in ecotonal northern Alaska, USA, for the years 2003–2100. We compared energy feedbacks associated with increases in biomass to energy feedbacks associated with changes in the duration of the snow-free season. We based our simulations on nine input climate scenarios from the Intergovernmental Panel on Climate Change (IPCC) and a new version of the Terrestrial Ecosystem Model (TEM) that incorporates biogeochemistry, vegetation dynamics for multiple PFTs (e.g., trees, shrubs, grasses, sedges, mosses), multiple vegetation pools, and soil thermal regimes. We found mean increases in net primary productivity (NPP) in all PFTs. Most notably, birch (Betula spp.) in the shrub tundra showed increases that were at least three times larger than any other PFT. Increases in NPP were positively related to increases in growing-season length in the sedge tundra, but PFTs in boreal forest and shrub tundra showed a significant response to changes in light availability as well as growing-season length. Significant NPP responses to changes in vegetation uptake of nitrogen by PFT indicated that some PFTs were better competitors for nitrogen than other PFTs. While NPP increased, heterotrophic respiration (RH) also increased, resulting in decreases or no change in net ecosystem carbon uptake. Greater aboveground biomass from increased NPP produced a decrease in summer albedo, greater regional heat absorption (0.34 ± 0.23 W·m−2·10 yr−1 [mean ± SD]), and a positive feedback to climate warming. However, the decrease in albedo due to a shorter snow season (−5.1 ± 1.6 d/10 yr) resulted in much greater regional heat

    Modelling the future suitable climate space for tree species has become a widely used tool for forest management planning under global climate change. Teak ( Tectona grandis) is one of the most valuable tropical hardwood species in the international timber market, and natural teak forests are distributed from India through Myanmar, Laos and Thailand. The extents of teak forests are shrinking due to deforestation and the local impacts of global climate change. However, the direct impacts of climate changes on the continental-scale distributions of native and non-native teak have not been examined. In this study, we developed a species distribution model for teak across its entire native distribution in tropical Asia, and its non-native distribution in Bangladesh. We used presence-only records of trees and twelve environmental variables that were most representative for current teak distributions in South and Southeast Asia. MaxEnt (maximum entropy) models were used to model the distributions of teak under current and future climate scenarios. We found that land use/land cover change and elevation were the two most important variables explaining the current and future distributions of native and non-native teak in tropical Asia. Changes in annual precipitation, precipitation seasonality and annual mean actual evapotranspiration may result in shifts in the distributions of teak across tropical Asia. We discuss the implications for the conservation of critical teak habitats, forest management planning, and risks of biological invasion that may occur due to its cultivation in non-native ranges.

    The development of human civilisations has occurred at a time of stable climate. This climate stability is now threatened by human activity. The rising global climate risk occurs at a decisive moment for world development. World nations are currently discussing a global development agenda consequent to the Millennium Development Goals (MDGs), which ends in 2015. It is increasingly possible to envisage a world where absolute poverty is largely eradicated within one generation and where ambitious goals on universal access and equal opportunities for dignified lives are adopted. These grand aspirations for a world population approaching or even exceeding nine billion in 2050 is threatened by substantial global environmental risks and by rising inequality. Research shows that development gains, in both rich and poor nations, can be undermined by social, economic and ecological problems caused by human-induced global environmental change. Climate risks, and associated changes in marine and terrestrial ecosystems that regulate the resilience of the climate system, are at the forefront of these global risks. We, as citizens with a strong engagement in Earth system science and socio-ecological dynamics, share the vision of a more equitable and prosperous future for the world, yet we also see threats to this future from shifts in climate and environmental processes. Without collaborative action now, our shared Earth system may not be able to sustainably support a large proportion of humanity in the decades ahead.

  13. Climate controls the distribution of a widespread invasive species: Implications for future range expansion

    1. Two dominant drivers of species distributions are climate and habitat, both of which are changing rapidly. Understanding the relative importance of variables that can control distributions is critical, especially for invasive species that may spread rapidly and have strong effects on ecosystems. 2. Here, we examine the relative importance of climate and habitat variables in controlling the distribution of the widespread invasive freshwater clam Corbicula fluminea, and we model its future distribution under a suite of climate scenarios using logistic regression and maximum entropy modelling (MaxEnt). 3. Logistic regression identified climate variables as more important than habitat variables in controlling Corbicula distribution. MaxEnt modelling predicted Corbicula's range expansion westward and northward to occupy half of the contiguous United States. By 2080, Corbicula's potential range will expand 25–32%, with more than half of the continental United States being climatically suitable. 4. Our combination of multiple approaches has revealed the importance of climate over habitat in controlling Corbicula's distribution and validates the climate-only MaxEnt model, which can readily examine the consequences of future climate projections. 5. Given the strong influence of climate variables on Corbicula's distribution, as well as Corbicula's ability to disperse quickly and over long distances, Corbicula is poised to expand into New England and the northern Midwest of the United States. Thus, the direct effects of climate change will probably be compounded by the addition of Corbicula and its own influences on ecosystem function.

    Bromoform and methyl iodide are both methane-like hydrocarbons with a halogen atom replacing one or more of the hydrogen atoms. Both of these compounds occur naturally in the environment as a result of their production from seaweed and kelp. They are of interest to climate science as a result of their catalytic destruction of boundary layer ozone (a potent greenhouse gas) and, specifically for methyl iodide, the proposed role in the formation of new cloud condensation nuclei with implications for climate. In this paper, the currently available data on the distribution of bromoform and methyl iodide are analysed and contrasted to show that the concentrations of bromoform and methyl iodide do not correlate, that, in contrast to bromoform, the parameterization of sea surface methyl iodide concentrations demands only the sea surface temperature, and that the pelagic distribution of methyl iodide appears to follow the solar zenith angle. These three observations together suggest that, while the pelagic source of bromoform is mostly biogenic, the source of methyl iodide is photochemical. This has implications for the understanding of planetary boundary layer chemistry and potential organohalogen mediated feedbacks to climate.

    2013-12-01

    Recent reports and scholarship have suggested that adapting to current climate variability may represent a "no regrets" strategy for adapting to climate change. Filling "adaptation deficits" and other approaches that rely on addressing current vulnerabilities are of course helpful for responding to current climate variability, but we find here that they are not sufficient for adapting to climate change. First, following a comprehensive review and unique synthesis of the natural hazards and climate adaptation literatures, we advance six reasons why adapting to climate variability is not sufficient for adapting to climate change: 1) Vulnerability is different at different levels of exposure; 2) Coping with climate variability is not equivalent to adaptation to longer term change; 3) The socioeconomic context for vulnerability is constantly changing; 4) The perception of risk associated with climate variability does not necessarily promote adaptive behavior in the face of climate change; 5) Adaptations made to short term climate variability may reduce the flexibility of the system in the long term; and 6) Adaptive actions may shift vulnerabilities to other parts of the system or to other people. Instead we suggest that decision makers faced with choices to adapt to climate change must consider the dynamics of vulnerability in a connected system-- how choices made in one part of the system might impact other valued outcomes or even create new vulnerabilities. Furthermore we suggest that rather than expressing climate change adaptation as an extension of adaptation to climate variability, the research and practice communities would do well to articulate adaptation as an imperfect policy, with tradeoffs and consequences and that decisions be prioritized to preserve flexibility be revisited often as climate change unfolds. We then present the results of a number of empirical studies of decision making for drought in urban water systems in the United States to understand

There is a lack of studies with good sample size that provide a comprehensive psychological profile of women presenting to specialist chronic pain clinics. Therefore, the objective of this study was to describe the psychological profile of a representative sample of women presenting with CPP at a tertiary referral center. Design: This was a cross-sectional study. Women were asked to complete a questionnaire assessing symptoms of anxiety and depression, pain severity and interference, pain self-efficacy and catastrophizing beliefs, and sexual functioning. Methods: One-hundred and seventy-five women with CPP were recruited when they attended their initial assessment at a specialist CPP clinic of the Royal Women’s Hospital, a public ­hospital in Melbourne, Australia. Results: Over 75% of the participants had experienced pain for longer than 2 years. Fifty-three percent of women experienced either moderate or severe anxiety, and 26.7% experienced moderate-to-severe depression. There were strong correlations between depressive symptoms and pain interference, pain catastrophizing and self-efficacy beliefs. Conclusion: Our findings confirm previous evidence for high levels of psychological distress and functional impairment associated with this condition, and extend these findings by including measures that are highly relevant to treatment planning, such as thinking styles and pain self-efficacy. Therefore, treatment of this complex condition needs to be holistic, and a multi

    2016-01-01

    Full Text Available The regional climate of Nusa Tenggara Barat (NTB Province, eastern Indonesia is simulated for 130 years (1971–2100 for the SRES A2 Delayed Development or ‘Business as Usual’ emissions scenario using the CSIRO conformal-cubic atmospheric model (CCAM. Regional climate simulations are generated using a multiple downscaling technique where a CCAM 200 km uniform-grid global simulation is driven by bias-corrected sea surface temperatures (SSTs from host coupled Global Climate Models (GCMs. Next, the 200 km resolution CCAM simulations are dynamically downscaled to 14 km resolution for the islands of Lombok and Sumbawa. To provide an ensemble of results, separate simulations are performed from six host GCMs. The present-day model results are validated against available observations. Generally, the CCAM 14 km resolution simulations produce rainfall, maximum and minimum temperatures that are similar to the observations. However, the 14 km simulations have rainfall biases of around 5 mm/day in the wet December–February season and lesser biases in the other seasons. Climate projections are examined for two future time intervals centred on 2030 and 2060. The simulations of rainfall changes by 2060 suggest both increases and decreases of up to 5% in December–February, with more acute declines of 10% in some areas, and decreases of up to 10% in March–May. For the other seasons, generally little change is simulated. The regional temperatures are projected to increase by about 1 °C by 2030 and 1.6–2 °C by 2060. The high-resolution model outputs enable detailed differentiation between locations across the islands. Our results show that due to orographic effects there are steep climate gradients, resulting in significant local differences in climate projections. We discuss the challenges and implications of these results for adaptation planning.

    Climate change models indicate that the Arctic regions will see a change in climate over the next 100 years. This will have a significant impact on the environment and natural resources, as well as on the communities that depend on them. This symposium outlined some of the major impacts of climate change already occurring in northern environments, as well as those likely to occur in the near future. The policy implications of these impacts were also examined, as well as ways in which the science of climate change may be used to further develop policy. The first session focused on scientific methods of climate change research, including the use of measuring instruments to detect changes in the Arctic Ocean Basin. The second session presented details of northern ecosystems, including tree line shifts and species currently at risk. Issues concerning stewardship and responsibility were also examined. The third session discussed the necessity of developing a mechanism to strengthen the information flow between the scientific community and policy leaders. Different climate models vary in their projections, and a universally accepted standard for validation and calibration must be established. The fourth session discussed the development of a framework to address cumulative effects and take into account various stakeholders, environmental impacts and other concerns specific to the Northwest Territories. The fifth session suggested ways in which international co-operation can increase and facilitate policy making. Open discussions followed each session. It was concluded that Arctic researchers and policy makers need to rethink the ways in which research planning and information dissemination is approached. It was suggested that opportunities for global collaboration should be explored. tabs., figs.

  13. Impacts of climate projections on water balance and implications on olive crop in Minas Gerais

    Directory of Open Access Journals (Sweden)

    Diego F. dos Santos

    Full Text Available ABSTRACT Minas Gerais is vulnerable to climate change, with negative impacts on water balance and changes in the cultivation of several crops. Currently, the olive crop has been an alternative source for farmers, especially those in the South of the state. However, there is no information on areas with climatic conditions suitable for olive cultivation, as well as the possible impacts of climate change. The aim of this study was to verify the impact of climate projections on water balance and agroclimatic zoning for olive cultivation in the Minas Gerais, based on current climate conditions (1980-2011, and different climate change projections for three future periods (2011-2040, 2041-2070 and 2071-2100. For the current climate, Minas Gerais showed 37% of suitable area, 15% of marginal area and 48% of unsuitable area for olive cultivation. For the period 2071-2100, only 4% was classified as suitable area, 6% as marginal area and 90% as unsuitable. Projections of climate change, of both temperature and rainfall, will affect the olive cultivation, substantially reducing the suitable area in the entire state.

    2013-03-01

    The purpose of this review is to investigate literature related to organizational climate, define organizational climate, and identify its domains for nurse practitioner (NP) practice in primary care settings. A search was conducted using MEDLINE, PubMed, HealthSTAR/Ovid, ISI Web of Science, and several other health policy and nursingy databases. In primary care settings, organizational climate for NPs is a set of organizational attributes, which are perceived by NPs about their practice setting, emerge from the way the organization interacts with NPs, and affect NP behaviors and outcomes. Autonomy, NP-physician relations, and professional visibility were identified as organizational climate domains. NPs should be encouraged to assess organizational climate in their workplace and choose organizations that promote autonomy, collegiality between NPs and physicians, and encourage professional visibility. Organizational and NP awareness of qualities that foster NP practice will be a first step for developing strategies to creating an optimal organizational climate for NPs to deliver high-quality care. More research is needed to develop a comprehensive conceptual framework for organizational climate and develop new instruments to accurately measure organizational climate and link it to NP and patient outcomes. ©2012 The Author(s) Journal compilation ©2012 American Association of Nurse Practitioners.

  17. Implications of climate variability for the detection of multiple equilibria and for rapid transitions in the atmosphere-vegetation system

    Paleoclimatic records indicate a decline of vegetation cover in the Western Sahara at the end of the African Humid Period (about 5,500 years before present). Modelling studies have shown that this phenomenon may be interpreted as a critical transition that results from a bifurcation in the atmosphere-vegetation system. However, the stability properties of this system are closely linked to climate variability and depend on the climate model and the methods of analysis. By coupling the Planet Simulator (PlaSim), an atmosphere model of intermediate complexity, with the simple dynamic vegetation model VECODE, we assess previous methods for the detection of multiple equilibria, and demonstrate their limitations. In particular, a stability diagram can yield misleading results because of spatial interactions, and the system's steady state and its dependency on initial conditions are affected by atmospheric variability and nonlinearities. In addition, we analyse the implications of climate variability for the abruptness of a vegetation decline. We find that a vegetation collapse can happen at different locations at different times. These collapses are possible despite large and uncorrelated climate variability. Because of the nonlinear relation between vegetation dynamics and precipitation the green state is initially stabilised by the high variability. When precipitation falls below a critical threshold, the desert state is stabilised as variability is then also decreased. (orig.)

    While natural gas produces lower carbon dioxide emissions than diesel during combustion, if enough methane is emitted across the fuel cycle, then switching a heavy-duty truck fleet from diesel to natural gas can produce net climate damages (more radiative forcing) for decades. Using the Technology Warming Potential methodology, we assess the climate implications of a diesel to natural gas switch in heavy-duty trucks. We consider spark ignition (SI) and high-pressure direct injection (HPDI) natural gas engines and compressed and liquefied natural gas. Given uncertainty surrounding several key assumptions and the potential for technology to evolve, results are evaluated for a range of inputs for well-to-pump natural gas loss rates, vehicle efficiency, and pump-to-wheels (in-use) methane emissions. Using reference case assumptions reflecting currently available data, we find that converting heavy-duty truck fleets leads to damages to the climate for several decades: around 70-90 years for the SI cases, and 50 years for the more efficient HPDI. Our range of results indicates that these fuel switches have the potential to produce climate benefits on all time frames, but combinations of significant well-to-wheels methane emissions reductions and natural gas vehicle efficiency improvements would be required.

    Changes in water temperatures caused by climate change in California's Sacramento–San Joaquin Delta will affect the ecosystem through physiological rates of fishes and invertebrates. This study presents statistical models that can be used to forecast water temperature within the Delta as a response to atmospheric conditions. The daily average model performed well (R2 values greater than 0.93 during verification periods) for all stations within the Delta and San Francisco Bay provided there was at least 1 year of calibration data. To provide long-term projections of Delta water temperature, we forced the model with downscaled data from climate scenarios. Based on these projections, the ecological implications for the delta smelt, a key species, were assessed based on temperature thresholds. The model forecasts increases in the number of days above temperatures causing high mortality (especially along the Sacramento River) and a shift in thermal conditions for spawning to earlier in the year.

    The 1972 Clean Water Act was passed to protect chemical, physical, and biological integrity of United States' waters. The U.S. Environmental Protection Agency and U.S. Army Corps of Engineers codified a new "waters of the United States" rule on June 29, 2015, because several Supreme Court case decisions caused confusion with the existing rule. Climate change could affect this rule through connectivity between groundwater and surface waters; floodplain waters and the 100-year floodplain; changes in jurisdictional status; and sea level rise on coastal ecosystems. Four approaches are discussed for handling these implications: (1) "Wait and see"; (2) changes to the rule; (3) use guidance documents; (4) Congress statutorily defining "waters of the United States." The approach chosen should be legally defensible and achieved in a timely fashion to provide protection to "waters of the United States" in proactive consideration of scientifically documented effects of climate change on aquatic ecosystems.

  1. Global climate change implications for coastal and offshore oil and gas development

    2011-01-01

    The discussion and debate about climate change and oil and gas resource development has generally focused on how fossil fuel use affects the Earth's climate. This paper explores how the changing climate is likely to affect oil and gas operations in low-lying coastal areas and the outer continental shelf. Oil and gas production in these regions comprises a large sector of the economies of many energy producing nations. Six key climate change drivers in coastal and marine regions are characterized with respect to oil and gas development: changes in carbon dioxide levels and ocean acidity, air and water temperature, precipitation patterns, the rate of sea level rise, storm intensity, and wave regime. These key drivers have the potential to independently and cumulatively affect coastal and offshore oil and gas exploration, production, and transportation, and several impacts of climate change have already been observed in North America. ?? 2011.

    We examined impacts of future climate scenarios on flow regimes and how predicted changes might affect river ecosystems. We examined two case studies: Cle Elum River, Washington, and Chattahoochee-Apalachicola River Basin, Georgia and Florida. These rivers had available downscaled global circulation model (GCM) data and allowed us to analyse the effects of future climate scenarios on rivers with (1) different hydrographs, (2) high future water demands, and (3) a river-floodplain system. We compared observed flow regimes to those predicted under future climate scenarios to describe the extent and type of changes predicted to occur. Daily stream flow under future climate scenarios was created by either statistically downscaling GCMs (Cle Elum) or creating a regression model between climatological parameters predicted from GCMs and stream flow (Chattahoochee-Apalachicola). Flow regimes were examined for changes from current conditions with respect to ecologically relevant features including the magnitude and timing of minimum and maximum flows. The Cle Elum's hydrograph under future climate scenarios showed a dramatic shift in the timing of peak flows and lower low flow of a longer duration. These changes could mean higher summer water temperatures, lower summer dissolved oxygen, and reduced survival of larval fishes. The Chattahoochee-Apalachicola basin is heavily impacted by dams and water withdrawals for human consumption; therefore, we made comparisons between pre-large dam conditions, current conditions, current conditions with future demand, and future climate scenarios with future demand to separate climate change effects and other anthropogenic impacts. Dam construction, future climate, and future demand decreased the flow variability of the river. In addition, minimum flows were lower under future climate scenarios. These changes could decrease the connectivity of the channel and the floodplain, decrease habitat availability, and potentially lower the ability

    Full Text Available Climate change is most likely to introduce an additional stress to already stressed water systems in developing countries. Climate change is inherently linked with the hydrological cycle and is expected to cause significant alterations in regional water resources systems necessitating measures for adaptation and mitigation. Increasing temperatures, for example, are likely to change precipitation patterns resulting in alterations of regional water availability, evapotranspirative water demand of crops and vegetation, extremes of floods and droughts, and water quality. A comprehensive assessment of regional hydrological impacts of climate change is thus necessary. Global climate model simulations provide future projections of the climate system taking into consideration changes in external forcings, such as atmospheric carbon-dioxide and aerosols, especially those resulting from anthropogenic emissions. However, such simulations are typically run at a coarse scale, and are not equipped to reproduce regional hydrological processes. This paper summarizes recent research on the assessment of climate change impacts on regional hydrology, addressing the scale and physical processes mismatch issues. Particular attention is given to changes in water availability, irrigation demands and water quality. This paper also includes description of the methodologies developed to address uncertainties in the projections resulting from incomplete knowledge about future evolution of the human-induced emissions and from using multiple climate models. Approaches for investigating possible causes of historically observed changes in regional hydrological variables are also discussed. Illustrations of all the above-mentioned methods are provided for Indian regions with a view to specifically aiding water management in India.

    Full Text Available Geobiocoenological landscape typology, which is used in landscape planning in the Czech Republic, includes vegetation zonation of the landscape. Vegetation zones are determined by climatic conditions. Changes in climatic conditions will probably be manifested in the shift of vegetation zones in the landscape. Mathematical geobiocoenological model of vegetation zonation of the landscape is based on the general ecological relationship between the current vegetation zonation and present climatic conditions and the assumption that this general relationship will be maintained in the future. The paper presents the application of the model using the example of the prediction of changes in climatic conditions for the Norway spruce (the first-generation of the model and grapevine (the second-generation of the model in the Czech Republic. In the case of the Norway spruce example, the model shows that the predicted changes in climatic conditions will prevent the cultivation of the spruce in the Czech Republic outside its natural range in mountainous areas. The results of the presented model for grapevine show significant enlargement of areas climatically suitable for growing grapes within the studied area.These examples demonstrate the potential for the application of geobiocoenological landscape typology in the modeling of the effects of climate change in the landscape.

    This paper gives a projection of the possible damage of climate change on the agriculture sector of Pakistan for the period 2012-2037, based on a dynamic approach, using an environment-related applied computable general equilibrium model (CGE). Climate damage projections depict an upward trend for the period of review and are found to be higher than the global average. Further, the damage to the agricultural sector exceeds that for the overall economy. By sector, climatic damage disproportionately affects the major and minor crops, livestock and fisheries. The largest losses following climate change, relative to the other agricultural sectors, are expected for livestock. The reason for this is the orthodox system of production for livestock, with a low adaptability to negative shocks of climate change. Overall, the findings reveal the high exposure of the agriculture sector to climate damage. In this regard, policymakers in Pakistan should take seriously the effects of climate change on agriculture and consider suitable technology to mitigate those damages.

    The Mid-Pliocene is the most recent interval in the Earth's history to have experienced warming of the magnitude predicted for the second half of the twenty-first century and is, therefore, a possible analogue for future climate conditions. With continents basically in their current positions and atmospheric CO2 similar to early twenty-first century values, the cause of Mid-Pliocene warmth remains elusive. Understanding the behaviour of the North Atlantic Ocean during the Mid-Pliocene is integral to evaluating future climate scenarios owing to its role in deep water formation and its sensitivity to climate change. Under the framework of the Pliocene Research, Interpretation and Synoptic Mapping (PRISM) sea surface reconstruction, we synthesize Mid-Pliocene North Atlantic studies by PRISM members and others, describing each region of the North Atlantic in terms of palaeoceanography. We then relate Mid-Pliocene sea surface conditions to expectations of future warming. The results of the data and climate model comparisons suggest that the North Atlantic is more sensitive to climate change than is suggested by climate model simulations, raising the concern that estimates of future climate change are conservative.

    Full Text Available Understanding the role of climatic factors on crop yields is essential in predicting the future impact of climate change. In order to understand the influence of climatic factors on OSR, detailed farm-level panel data from 2566 farms across 67 counties of the 6 major OSR production regions in China, from the surveys conducted by the national OSR industry project between 2008 and 2013, were used to examine the contribution of changes in selected climatic variables between 2008 and 2013 to yield variation. Spatial and temporal patterns of the relationships between OSR yield, climatic factors were estimated together with the effects of farmer adaptation and management practices on yield variability. The analysis revealed that yields in the low-latitude production regions were more sensitive to temperature increases and likely to decline. Precipitation iwas the most influential factor on yield at the first two growth stages; temperature and sunshine hours were most important at the third and fourth growth stages, respectively. Labour input was the most influential management factor affecting yields compared with fertilizer and other inputs. The study concludes that projection of future climate change impacts will need inter alia to incorporate more sophisticated and detailed measures of climatic variables than simple means of temperature and precipitation, incorporating timing in relation to plant growth and yield.

  9. Carbon Stocks and Climate Change: Management Implications in Northern Arizona Ponderosa Pine Forests

    2014-04-01

    Full Text Available Researchers have observed climate-driven shifts of forest types to higher elevations in the Southwestern US and predict further migration coupled with large-scale mortality events proportional to increases in radiative forcing. Range contractions of forests are likely to impact the total carbon stored within a stand. This study examines the dynamics of Pinus ponderosa stands under three climate change scenarios in Northern Arizona using the Climate Forest Vegetation Simulator (Climate-FVS model to project changes in carbon pools. A sample of 90 stands were grouped according to three elevational ranges; low- (1951 to 2194 m, mid- (2194 to 2499 m, and high- (2499 to 2682 m. elevation stands. Growth, mortality, and carbon stores were simulated in the Climate-FVS over a 100 year timespan. We further simulated three management scenarios for each elevational gradient and climate scenario. Management included (1 a no-management scenario, (2 an intensive-management scenario characterized by thinning from below to a residual basal area (BA of 18 m2/ha in conjunction with a prescribed burn every 10 years, and (3 a moderate-management scenario characterized by a thin-from-below treatment to a residual BA of 28 m2/ha coupled with a prescribed burn every 20 years. Results indicate that any increase in aridity due to climate change will produce substantial mortality throughout the elevational range of ponderosa pine stands, with lower elevation stands projected to experience the most devastating effects. Management was only effective for the intensive-management scenario; stands receiving this treatment schedule maintained moderately consistent levels of basal area and demonstrated a higher level of resilience to climate change relative to the two other management scenarios. The results of this study indicate that management can improve resiliency to climate change, however, resource managers may need to employ more intensive thinning treatments than

    It has been increasingly suggested that the world's climate is going to change in the next several decades, primarily as a result of anthropogenic perturbations to the global carbon cycle brought about by fossil fuel burning and large-scale deforestation. In order to cope with these future climatic changes, it is necessary that tools be developed to predict how complex systems respond to a given change of conditions. This report summarizes the status of our ability to model the planetary system that determines the climate. (ACR)

    Climate variability on interannual to multidecadal temporal scales has substantial implications for management and sustainability of water resources, yet are poorly understood throughout much of the United States. Climate forcings on these timescales partially control precipitation distribution, temperature fluctuations, drought occurrence and severity, streamflow, and recharge. Reliable predictions of future climate and subsequent adaptation of groundwater management strategies in vulnerable aquifers, such as the Central Valley aquifer located in central California of the United States, requires improved understanding of climate variability on interannual to multidecadal timescales and the associated responses in recharge rates. Groundwater withdrawals from the Central Valley aquifer are the second largest of all aquifers in the United States and are used to support one of the largest agricultural economies. However, the effects of the El Niño Southern Oscillation (ENSO) (2 to 6 year cycle), Pacific Decadal Oscillation (PDO) (10 to 25 year cycle), and Atlantic Multidecadal Oscillation (AMO) (50 to 80 year cycle) on recharge rates and groundwater levels in the Central Valley aquifer previously have not been quantified. In this study, singular spectrum analysis (SSA) was used to identify the principal components of groundwater level time series from selected wells in Central Valley aquifer that contribute to the greatest amount of variance in the record. In each of the time series analyzed, the PDO was the most significant contributor to groundwater level fluctuations. Wavelet analysis was also used to examine the nonstationary phase relation of multiple time series to identify significance and duration of each forcing. A consistent phase relation of multiple signals suggests possible coherence between climate forcings and groundwater levels, and also indicates the effect of the PDO on groundwater levels. These findings support the conclusion that interannual to

    Infectious diseases are common in marine environments, but the effects of a changing climate on marine pathogens are not well understood. Here we review current knowledge about how the climate drives host-pathogen interactions and infectious disease outbreaks. Climate-related impacts on marine diseases are being documented in corals, shellfish, finfish, and humans; these impacts are less clearly linked for other organisms. Oceans and people are inextricably linked, and marine diseases can both directly and indirectly affect human health, livelihoods, and well-being. We recommend an adaptive management approach to better increase the resilience of ocean systems vulnerable to marine diseases in a changing climate. Land-based management methods of quarantining, culling, and vaccinating are not successful in the ocean; therefore, forecasting conditions that lead to outbreaks and designing tools/approaches to influence these conditions may be the best way to manage marine disease.

    The denudation history of active orogens is often interpreted in the context of modern climate gradients. Despite the influence of climatic conditions on erosion rates, information about paleoclimate evolution is often not available and thus not considered when denudation histories are interpreted. In this study, we analyze output from paleoclimate simulations conducted with ECHAM5-wiso at T159 (ca. 80x80km) resolution. Specifically, we analyze simulations of pre-industrial (PI, pre-1850), Mid-Holocene (MH, ca. 6ka), Last Glacial Maximum (LGM, ca. 21ka) and Pliocene (PLIO, ca. 3ka) climates and focus on a selection of orogen syntaxes as study regions (e.g. Himalaya, SE Alaska, Cascadia, and Central Andes). For the selected region, we carry out a cluster analysis using a hybrid of hierarchical and k-means clustering procedures using mean annual temperature (MAT), temperature amplitude, mean annual precipitation (MAP), precipitation amplitude and u-wind and v-wind in different months to provide a general overview of paleoclimates in the study regions. Additionally, we quantify differences between paleoclimates by applying two-group linear discrimination analyses to the simulation output for a similar selection of variables. Results indicate the largest differences to the PI climate are observed for the LGM and PLIO climates in the form of widespread cooling and reduced precipitation in the LGM and warming and enhanced precipitation during the PLIO. These global trends can be observed for most locations in the investigated areas, but the strength varies regionally and the trends in precipitation are less uniform than trends in temperatures. The LGM climate shows the largest deviation in annual precipitation from the PI climate, and shows enhanced precipitation in the temperate Andes, and coastal regions for both SE Alaska and the US Pacific Northwest Pacific. Furthermore, LGM precipitation is reduced in the western Himalayas and enhanced in the eastern Himalayas

    2017-04-01

    Anthropogenic emissions and land-use changes have modified atmospheric aerosol concentrations and size distributions over time. Understanding pre-industrial conditions and changes in organic aerosol due to anthropogenic activities is important because these features 1) influence estimates of aerosol radiative forcing and 2) can confound estimates of the historical response of climate to increases in greenhouse gases (e.g. the 'climate sensitivity'). Secondary organic aerosol (SOA), formed in the atmosphere by oxidation of organic gases, often represents a major fraction of global submicron-sized atmospheric organic aerosol. Over the past decade, significant advances in understanding SOA properties and formation mechanisms have occurred through measurements, yet current climate models typically do not comprehensively include all important processes. This presentation is based on a US Department of Energy Atmospheric Systems Research sponsored workshop, which highlighted key SOA processes overlooked in climate models that could greatly affect climate forcing estimates. We will highlight the importance of processes that influence the growth of SOA particles to sizes relevant for clouds and radiative forcing, including: formation of extremely low-volatility organics in the gas-phase; isoprene epoxydiols (IEPOX) multi-phase chemistry; particle-phase oligomerization; and physical properties such as viscosity. We also highlight some of the recently discovered important processes that involve interactions between natural biogenic emissions and anthropogenic emissions such as effects of sulfur and NOx emissions on SOA. We will present examples of integrated model-measurement studies that relate the observed evolution of organic aerosol mass and number with knowledge of particle properties such as volatility and viscosity. We will also highlight the importance of continuing efforts to rank the most influential SOA processes that affect climate forcing, but are often missing

    Cemented soils formed via reactions with salts are studied here and provide information about the climate when they formed. Spectroscopic and microprobe studies have been performed on cemented volcanic crusts in order to learn about the composition of these materials, how they formed, and what they can tell us about climatic interactions with surface material on Mars to form cemented soils. These crusts include carbonate, sulfate and opaline components that may all be present in cemented soil units on Mars.

    Griffin, Dale W.; Ragaini, Richard C.

    2010-01-01

    The global dispersion of desert dust through Earth’s atmosphere is greatly influenced by temperature. Temporal analyses of ice core data have demonstrated that enhanced dust dispersion occurs during glacial events. This is due to an increase in ice cover, which results in an increase in drier terrestrial cover. A shorter temporal analysis of dust dispersion data over the last 40 years has demonstrated an increase in dust transport. Climate systems or events such as the North Atlantic Oscillation, the Indian Ocean subtropical High, Pacific Decadal Oscillation, and El Nino-Sothern Oscillation are known to influence global short-term dust dispersion occurrence and transport routes. Anthropogenic influences on dust transport include deforestation, harmful use of topsoil for agriculture as observed during the American Dust Bowl period, and the creation of dry seas (Aral Sea) and lakes (Lake Owens in California and Lake Chad in North Africa) through the diversion of source waters (for irrigation and drinking water supplies). Constituents of desert dust both from source regions (pathogenic microorganisms, organic and inorganic toxins) and those scavenged through atmospheric transport (i.e., industrial and agricultural emissions) are known to directly impact human and ecosystem health. This presentation will present a review of global scale dust storms and how these events can be both a detriment and benefit to various organisms in downwind environments.

    To validate a framework of factors that influence the relationship of transformational leadership and safety climate, and to enable testing of safety chain factors by generating hypotheses regarding their mediating and moderating effects. Understanding the patient safety chain and mechanisms by which leaders affect a strong climate of safety is essential to transformational leadership practice, education, and research. A systematic review of leadership and safety literature was used to develop an organising framework of factors proposed to influence the climate of safety. A panel of 25 international experts in leadership and safety engaged a three-round modified Delphi study with Likert-scored surveys. Eighty per cent of participating experts from six countries were retained to the final survey round. Consensus (>66% agreement) was achieved on 40 factors believed to influence safety climate in the acute care setting. Consensus regarding specific factors that play important roles in an organisation's climate of safety can be reached. Generally, the demonstration of leadership commitment to safety is key to cultivating a culture of patient safety. Transformational nurse leaders should consider and employ all three categories of factors in daily leadership activities and decision-making to drive a strong climate of patient safety. © 2017 John Wiley & Sons Ltd.

    Deforestation is a major threat to tropical forests worldwide, contributing up to one-fifth of global carbon emissions into the atmosphere. Despite protection efforts, deforestation of tropical forests has continued in recent years. Providing incentives to reducing deforestation has been proposed in the United Nations Framework Convention on Climate Change (UNFCCC) Bali negotiations in 2007 to decelerate emissions from deforestation (REDD—reduced emissions from deforestation and forest degradation). A number of methodological issues such as ensuring permanence, establishing reference emissions levels that do not reward business-as-usual and having a measuring, reporting and verification system in place are essential elements in implementing successful REDD schemes. To assess the combined impacts of climate and land-use change on tropical forest carbon stocks in the 21st century, we use a dynamic global vegetation model (LPJ DGVM) driven by five different climate change projections under a given greenhouse gas emission scenario (SRES A2) and two contrasting land-use change scenarios. We find that even under a complete stop of deforestation after the period of the Kyoto Protocol (post-2012) some countries may continue to lose carbon stocks due to climate change. Especially at risk is tropical Latin America, although the presence and magnitude of the risk depends on the climate change scenario. By contrast, strong protection of forests could increase carbon uptake in many tropical countries, due to CO2 fertilization effects, even under altered climate regimes.

    Substance abuse agencies have been slow to adopt and implement evidence-based practices (EBPs), due in part to poor provider morale and organizational climates that are not conducive to successful learning and integration of these practices. Person-organization fit theory suggests that alignment, or fit, between provider- and agency-level characteristics regarding the implementation of EBPs may influence provider morale and organizational learning climate and, thus, implementation success. The current study hypothesized that discrepancies, or lack of fit, between provider- and agency-level contextual factors would negatively predict provider morale and organizational learning climate, outcomes shown to be associated with successful EBP implementation. Direct service providers (n = 120) from four substance abuse treatment agencies responded to a survey involving provider morale, organizational learning climate, agency expectations for EBP use, agency resources for EBP use, and provider attitudes towards EBP use. Difference scores between combinations of provider- and agency-level factors were computed to model provider-agency fit. Quadratic regression analyses were conducted to more adequately and comprehensively model the level of the dependent variables across the entire "fit continuum". Discrepancies, or misfit, between agency expectations and provider attitudes and between agency resources and provider attitudes were associated with poorer provider morale and weaker organizational learning climate. For all hypotheses, the curvilinear model of provider-agency discrepancies significantly predicted provider morale and organizational learning climate, indicating that both directions of misfit (provider factors more favorable than agency factors, and vice-versa) were detrimental to morale and climate. However, outcomes were most negative when providers viewed EBPs favorably, but perceived that agency expectations and resources were less supportive of EBP use. The

    Cyanobacterial blooms are often a result of eutrophication. Recently, however, their expansion has also been found to be associated with changes in climate. To elucidate the effects of climatic variables on the expansion of cyanobacterial blooms in Taihu, China, we analyzed the relationships between climatic variables and bloom events which were retrieved by satellite images. We then assessed the contribution of each climate variable to the phenology of blooms using multiple regression models. Our study demonstrates that retrieving ecological information from satellite images is meritorious for large-scale and long-term ecological research in freshwater ecosystems. Our results show that the phenological changes of blooms at an inter-annual scale are strongly linked to climate in Taihu during the past 23 yr. Cyanobacterial blooms occur earlier and last longer with the increase of temperature, sunshine hours, and global radiation and the decrease of wind speed. Furthermore, the duration increases when the daily averages of maximum, mean, and minimum temperature each exceed 20.3 °C, 16.7 °C, and 13.7 °C, respectively. Among these factors, sunshine hours and wind speed are the primary contributors to the onset of the blooms, explaining 84.6% of their variability over the past 23 yr. These factors are also good predictors of the variability in the duration of annual blooms and determined 58.9% of the variability in this parameter. Our results indicate that when nutrients are in sufficiently high quantities to sustain the formation of cyanobacterial blooms, climatic variables become crucial in predicting cyanobacterial bloom events. Climate changes should be considered when we evaluate how much the amount of nutrients should be reduced in Taihu for lake management. Copyright © 2011 Elsevier Ltd. All rights reserved.

  11. Implications of Human Activities, Land Use Changes and Climate Variability in Mediterranean Lakes of Greece

    2016-10-01

    Full Text Available Lakes in the Mediterranean climate zone experience high variation in rainfall and are vulnerable to changes in climate, land cover and anthropogenically induced effects on water level and salinity. This paper presents the results from the analyses of spatiotemporal changes of land cover/uses at catchment scale of two connected lakes in Greece that have recently exhibited a dramatic loss of water volume, and investigates the potential role of climate change as a main driver of the lake water loss. The classification of the historical land cover/uses was based on a series of LANDSAT images from 1972 to 2011. Changes in the landscape structure were assessed using landscape metrics that were calculated with FRAGSTATS software. Climate data and temporal series of water level, conductivity and chloride concentration, were analyzed to investigate the potential role of climate variability to the lake hydrology and water quality. The results showed that between 1972 and 2011 almost 28% of Lake Vegoritis and 13% of Lake Petron were replaced by cultivations and reed beds. Landscape metrics showed that the lake catchment’s area is highly fragmented, indicating a heterogeneous spatial pattern and degradation of the rural habitats. Regarding the climatic factors, it appears that precipitation follows a declining trend correlating with water level fluctuations. The water level in Lake Vegoritis also correlated with the conductivity and chloride concentration, indicating a relationship between hydrological alteration and water quality. Overall, a combined effect of climate- and human-induced land cover changes appeared to be responsible for the drastic environmental changes that urge the need for implementing effective restoration and mitigation measures.

    Mountain ecosystems are extremely vulnerable to climate change. The real potential for adaptation depends upon the existence of a wide genetic diversity in trees populations, upon the adaptive genetic variation, respectively. Genetic diversity offers the guarantee that forest species can survive, adapt and evolve under the influence of changing environmental conditions. The aim of this study is to evaluate the genetic diversity and adaptive genetic potential of two local species - Norway spruce and European silver fir - in the context of regional climate change. Based on data from a long-term provenance experiments network and climate variables spanning over more than 50 years, we have investigated the impact of climatic factors on growth performance and adaptation of tree species. Our results indicate that climatic and geographic factors significantly affect forest site productivity. Mean annual temperature and annual precipitation amount were found to be statistically significant explanatory variables. Combining the additive genetic model with the analysis of nuclear markers we obtained different images of the genetic structure of tree populations. As genetic indicators we used: gene frequencies, genetic diversity, genetic differentiation, genetic variance, plasticity. Spatial genetic analyses have allowed identifying the genetic centers holding high genetic diversity which will be valuable sources of gene able to buffer the negative effects of future climate change. Correlations between the marginal populations and in the optimal vegetation, between the level of genetic diversity and ecosystem stability, will allow the assessment of future risks arising from current genetic structure. Therefore, the strategies for sustainable forest management have to rely on the adaptive genetic variation and local adaptation of the valuable genetic resources. This work was realized within the framework of the project GENCLIM (Evaluating the adaptive potential of the main

    Full Text Available Like other countries, the United Kingdom faces the unavoidable challenge of adapting to a changing climate. However, public perceptions of the risk posed by climate change and support for adaptation policies vary between countries. This article provides a UK-specific review of climate change beliefs, risk perceptions regarding potential climate change impacts, and attitudes towards climate change adaptation. We report on differences between expert and public conceptualisations of climate change risks. We also examine the effects of psychological distancing, climate change awareness, and hazard experience on both concerns about climate change and perceptions of the weather-related risks posed by climate change. Additionally, we review the effects of emotion, agency, perceived responsibility, place attachment, personal values and uncertainty on the willingness of UK residents to support and engage with climate change adaptation. We outline the implications of these factors for climate risk communication and highlight key areas for future research.

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Water eutrophication has become one of the most serious aquatic environmental problems around the world. More and more research has indicated climate change as a major natural factor that will lead to the acceleration of eutrophication in rivers and lakes. However, understanding the mechanism of climate change’s effect on water eutrophication is difficult due to the uncertainties caused by its complex, non-linear process. There is considerable uncertainty about the magnitude of future temperature changes, and how these will drive eutrophication in water bodies at regional scales under the effect of human activities. This review collects the existing international and domestic literature from the last 10 years, discussing the most sensitive factors of climate change (i.e., temperature, precipitation, wind, and solar radiation and analyzing their interaction with water eutrophication. Case studies of serious eutrophication and algal bloom problems in China are discussed to further demonstrate the conclusion. Finally, adaptation countermeasures and related implications are proposed in order to foster the development of sustainability strategies for water management in China.

    Guided by family systems and ecological theories, this study examined the multicontextual implications of family, school, and individual domains for adolescents' school success. The first goal of this study was to examine reciprocal influences among family climate, school attachment, and academic self-regulation (ASR) during the middle school years. The second goal was to test the relative impact of each of these domains on adolescents' school adjustment and academic achievement after the transition to high school. We applied a cross-lag structural equation modeling approach to longitudinal data from 979 students in the 6th grade and their families, followed over 5 measurement occasions, from 6th through 9th grade. Controlling for family income, parent education, and adolescent gender, the results revealed reciprocal relationships between the family climate and school attachment over time; both of these factors were related to increases in ASR over time. In turn, ASR was a robust predictor of academic success, with unique associations with school adjustment and academic achievement. Family climate and school adjustment had modest to marginal associations with school adjustment, and no association with academic achievement. Applications of these findings for family school interventions are discussed. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  16. Simulated vs. empirical weather responsiveness of crop yields: US evidence and implications for the agricultural impacts of climate change

    Global gridded crop models (GGCMs) are the workhorse of assessments of the agricultural impacts of climate change. Yet the changes in crop yields projected by different models in response to the same meteorological forcing can differ substantially. Through an inter-method comparison, we provide a first glimpse into the origins and implications of this divergence—both among GGCMs and between GGCMs and historical observations. We examine yields of rainfed maize, wheat, and soybeans simulated by six GGCMs as part of the Inter-Sectoral Impact Model Intercomparison Project-Fast Track (ISIMIP-FT) exercise, comparing 1981-2004 hindcast yields over the coterminous United States (US) against US Department of Agriculture (USDA) time series for about 1000 counties. Leveraging the empirical climate change impacts literature, we estimate reduced-form econometric models of crop yield responses to temperature and precipitation exposures for both GGCMs and observations. We find that up to 60% of the variance in both simulated and observed yields is attributable to weather variation. A majority of the GGCMs have difficulty reproducing the observed distribution of percentage yield anomalies, and exhibit aggregate responses that show yields to be more weather-sensitive than in the observational record over the predominant range of temperature and precipitation conditions. This disparity is largely attributable to heterogeneity in GGCMs’ responses, as opposed to uncertainty in historical weather forcings, and is responsible for widely divergent impacts of climate on future crop yields.

    An accurate representation of African aerosols in climate models is needed to understand the regional and global radiative forcing and climate impacts of aerosols, at present and under future climate change. However, aerosol simulations in regional climate models for Africa have not been well-tested. Africa contains the largest single source of biomass-burning smoke aerosols and dust globally. Although aerosols are short-lived relative to greenhouse gases, black carbon in particular is estimated to be second only to carbon dioxide in contributing to warming on a global scale. Moreover, Saharan dust is exported great distances over the Atlantic Ocean, affecting nutrient transport to regions like the Amazon rainforest, which can further impact climate. Biomass burning aerosols are also exported from Africa, westward from Angola over the Atlantic Ocean and off the southeastern coast of South Africa to the Indian Ocean. Here, we perform the first extensive quantitative evaluation of the Conformal-Cubic Atmospheric Model (CCAM) aerosol simulation against monitored data, focusing on aerosol optical depth (AOD) observations over Africa. We analyze historical regional simulations for 1999 - 2012 from CCAM consistent with the experimental design of CORDEX at 50 km global horizontal resolution, through the dynamical downscaling of ERA-Interim data reanalysis data, with the CMIP5 emissions inventory (RCP8.5 scenario). CCAM has a prognostic aerosol scheme for organic carbon, black carbon, sulfate, and dust, and non-prognostic sea salt. The CCAM AOD at 550nm was compared to AOD (observed at 440nm, adjusted to 550nm with the Ångström exponent) from long-term AERONET stations across Africa. Sites strongly impacted by dust and biomass burning and with long continuous records were prioritized. In general, the model captures the monthly trends of the AERONET data. This presentation provides a basis for understanding how well aerosol particles are represented over Africa in

    Full Text Available Climate change may impact soil health and productivity as a result of accelerated or decelerated rates of erosion. Previous studies suggest a greater risk of wind erosion on arid and semi-arid lands due to loss of biomass under a future warmer climate. There have been no studies conducted to assess the impact of climate change on wind erosion in the Columbia Plateau of the Pacific Northwest United States where wind erosion of agricultural lands can cause exceedance of national air quality standards. The Wind Erosion Prediction System (WEPS was used to assess wind erosion and PM10 (particulate matter ≤10 µm in aerodynamic diameter emissions under a future climate projected by downscaling 18 Global Climate Models (GCM for a conservative emissions pathway. Wind erosion simulations were conducted at Lacrosse and Lind, WA and Moro, OR on a winter wheat-summer fallow (WW-SF rotation and at Lind on an additional winter wheat-camelina-summer fallow (WW-Cam-SF rotation. Each rotation was subject to conservation or conventional tillage practices for a baseline (1970–1999 and mid-21st century climate (2035–2064. A significant increase in temperature and nominal increases in precipitation were projected by an ensemble of climate models for the Columbia Plateau by the mid-21st century. Soil and PM10 losses were 25–84% lower for a mid-21st century climate, due in part to greater biomass production associated with CO2 fertilization and warmer temperatures. The reduction in soil and PM10 loss is projected to be more apparent for conservation tillage practices in the future. Soil and PM10 losses were greater from a WW-Cam-SF rotation than WW-SF rotation when conservation tillage practices were employed during the fallow phase of the rotations. Despite accounting for differences in the length of each rotation, annual soil and PM10 losses remained higher for the WW-Cam-SF rotation than the WW-SF rotation. Soil and PM10 losses were more variable across

    2017-12-01

    Full Text Available Global climate change may enable invasive plant species (IPS to invade protected areas (PAs, but plant invasion on a global scale has not yet been explicitly addressed. Here, we mapped the potential invasion pathways for IPS in PAs across the globe and explored potential factors determining the pathways of plant invasion under climate change. We used species distribution modelling to estimate the suitable habitats of 386 IPS and applied a corridor analysis to compute the potential pathways of IPS in PAs under climate change. Subsequently, we analysed the potential factors affecting the pathways in PAs. According to our results, the main potential pathways of IPS in PAs are in Europe, eastern Australia, New Zealand, southern Africa, and eastern regions of South America and are strongly influenced by changes in temperature and precipitation. Protected areas can play an important role in preventing and controlling the spread of IPS under climate change. This is due to the fact that measures are taken to monitor climate change in detail, to provide effective management near or inside PAs, and to control the introduction of IPS with a high capacity for natural dispersal. A review of conservation policies in PAs is urgently needed.

While prior research has focused on species migrations per se, ecotones may respond to different environmental factors than species. Even if species can migrate in response to climate change, if ecotones do not they can function as hard barriers to species migrations, making ecotone migrations central to understanding species persistence under scenarios of climate change. We examined a 42-year span of aerial photographs and high resolution satellite imagery to calculate migration rates of timberline--the grassland-forest ecotone-inside and outside of protected areas in the high Peruvian Andes. We found that timberline in protected areas was more likely to migrate upward in elevation than in areas with frequent cattle grazing and fire. However, rates in both protected (0.24 m yr(-1 and unprotected (0.05 m yr(-1 areas are only 0.5-2.3% of the rates needed to stay in equilibrium with projected climate by 2100. These ecotone migration rates are 12.5 to 110 times slower than the observed species migration rates within the same forest, suggesting a barrier to migration for mid- and high-elevation species. We anticipate that the ecotone will be a hard barrier to migration under future climate change, leading to drastic population and biodiversity losses in the region unless intensive management steps are taken.

    Overwhelming evidence has shown that, from the Industrial Revolution to the present, human activities influence ground-level ozone (O 3 ) concentrations. Past studies demonstrate links between O 3 exposure and health. However, knowledge gaps remain in our understanding concerning the impacts of climate change mitigation policies on O 3 concentrations and health. Using a hybrid downscaling approach, we evaluated the separate impact of climate change and emission control policies on O 3 levels and associated excess mortality in the US in the 2050s under two Representative Concentration Pathways (RCPs). We show that, by the 2050s, under RCP4.5, increased O 3 levels due to combined climate change and emission control policies, could contribute to an increase of approximately 50 premature deaths annually nationwide in the US. The biggest impact, however, is seen under RCP8.5, where rises in O 3 concentrations are expected to result in over 2,200 additional premature deaths annually. The largest increases in O 3 are seen in RCP8.5 in the Northeast, the Southeast, the Central, and the West regions of the US. Additionally, when O 3 increases are examined by climate change and emissions contributions separately, the benefits of emissions mitigation efforts may significantly outweigh the effects of climate change mitigation policies on O 3 -related mortality.

    It is widely agreed that the concentration of greenhouse gases in the earth`s atmosphere is increasing, that this increase is a consequence of man`s activities, and that there is significant risk that this will lead to changes in the earth`s climate. The question is now being discussed what, if anything, we should be doing to minimize and/or adapt to changes in climate. Virtually every statement on this matter; from the US Office of Technology Assessment, to the National Academy of Science, to the Nairobi Declaration on Climatic Change, includes some recommendation for planting and protecting forests. In fact, forestry is intimately involved in the climate change debate for several reasons: changing climate patterns will affect existing forests, tropical deforestation is one of the major sources of greenhouse gases to the atmosphere, reforestation projects could remove additional carbon dioxide from the atmosphere and there is renewed interest in wood-based or other renewable fuels to replace fossil fuels. Part of the enthusiasm for forestry-related strategies in a greenhouse context is the perception that forests not only provide greenhouse benefits but also serve other desirable social objectives. This discussion will explore the current range of thinking in this area and try to stimulate additional thinking on the rationality of the forestry-based approaches and the challenges posed for US forestry.

    Natural scientists have made great strides in recent years to improve their understanding of the complex issue of global climate change. Despite the progress made, there continues to be a persistent gap between the knowledge and concern among members of the climate science community and translation of such scientific expertise into effective climate change policies and the general public’s behavioral choices. Communication is breaking down at the intersection of climate science, policy, and behavior change. Part of the reason is that, to date, social science research has not been sufficiently exploited to help individuals and groups incorporate information about climate change and environmental risk into decision making. The presentation will highlight research conducted at the Center for Research on Environmental Decisions (CRED). This presentation will discuss barriers to behavioral change and provide suggestions for improving communication about climate change: Typical science communication requires analytic processing, some level of expertise, at a minimum interest. For most people abstract information does not translate into powerful vivid images that would trigger action. Furthermore, we have found that people’s interpretation of scientific uncertainty can get in the way of using forecasts and projections. Other barriers include public risk perceptions and attitudes, cultural values, and myopia, as well as the importance that people place on self-interest/economic goals vs. collective interest/social goals. Many of these obstacles can be overcome and communication of climate change information can be improved by presenting a combination of affective information (vicarious experience, scenarios, narratives, and analogies) and scientific data; yet there are also downsides to the overuse of emotional appeals (such as the finite pool of worry and the single action bias); tapping into social affiliations and group identities can motivate the activation of

    There is increasing evidence that experiencing discrimination may contribute to poor mental health among Black Americans. However, few studies have distinguished between discrimination attributed to race versus other forms of discrimination or have compared differences in their psychological implications. Using nationally representative data on 5,191 Black Americans in the National Survey of American Life (NSAL; 2001-2003), this study examined serious psychological distress (SPD) in relation to discrimination attributed to racial versus nonracial causes and also investigated whether racial group identification may be a buffer. We found that discrimination was associated with greater odds of SPD, regardless of attribution. Racial attributions were associated with higher odds of SPD compared with attributions to nonracial causes for each level of discrimination. High racial group identification buffered the negative effect of moderate levels of both racially and nonracially attributed discrimination. Our results provide evidence for the negative influence of discrimination on SPD among Black Americans and indicate that high racial group identification may somewhat mitigate their negative mental health effects. Our study suggests that discrimination and racial group identification should be addressed to protect against psychological distress among Black Americans. © 2011 American Orthopsychiatric Association.

  7. Justice and Equity Implications of Climate Change Adaptation: A Theoretical Evaluation Framework

    2016-09-01

    Full Text Available Climate change affects human health, and climate change adaptation aims to reduce these risks through infrastructural, behavioral, and technological measures. However, attributing direct human health effects to climate change adaptation is difficult, causing an ethical dilemma between the need for evidence of strategies and their precautionary implementation before such evidence has been generated. In the absence of conclusive evidence for individual adaptation strategies, alternative approaches to the measurement of adaptation effectiveness need to be developed. This article proposes a theoretical framework and a set of guiding questions to assess effects of adaptation strategies on seven domains of health determinants, including social, economic, infrastructure, institutional, community, environmental, and cultural determinants of health. Its focus on advancing gender equity and environmental justice concurrently with the implementation of health-related adaptation could serve as a template for policymakers and researchers.

    Previous modeling of snow albedo, a key climate feedback parameter, follows the independent scattering approximation (ISA) such that snow grains are considered as a number of separate units with distances longer than wavelengths. Here we develop a new snow albedo model for widely observed close-packed snow grains internally mixed with black carbon (BC) and demonstrate that albedo simulations match closer to observations. Close packing results in a stronger light absorption for clean and BC-contaminated snow. Compared with ISA, close packing reduces pure snow albedos by up to 0.05, whereas it enhances BC-induced snow albedo reduction and associated surface radiative forcing by up to 15% (20%) for fresh (old) snow, with larger enhancements for stronger structure packing. Finally, our results suggest that BC-snow albedo forcing and snow albedo feedback (climate sensitivity) are underestimated in previous modeling studies, making snow close packing consideration a necessity in climate modeling and analysis.

    Recent climatic change has been recorded across the globe. Although environmental change is a characteristic feature of life on Earth and has played a major role in the evolution and global distribution of biodiversity, predicted future rates of climatic change, especially in temperature, are such that they will exceed any that has occurred over recent geological time. Climate change is considered as a key threat to biodiversity and to the structure and function of ecosystems that may already be subject to significant anthropogenic stress. The current understanding of climate change and its likely consequences for the fishes of Britain and Ireland and the surrounding seas are reviewed through a series of case studies detailing the likely response of several marine, diadromous and freshwater fishes to climate change. Changes in climate, and in particular, temperature have and will continue to affect fish at all levels of biological organization: cellular, individual, population, species, community and ecosystem, influencing physiological and ecological processes in a number of direct, indirect and complex ways. The response of fishes and of other aquatic taxa will vary according to their tolerances and life stage and are complex and difficult to predict. Fishes may respond directly to climate-change-related shifts in environmental processes or indirectly to other influences, such as community-level interactions with other taxa. However, the ability to adapt to the predicted changes in climate will vary between species and between habitats and there will be winners and losers. In marine habitats, recent changes in fish community structure will continue as fishes shift their distributions relative to their temperature preferences. This may lead to the loss of some economically important cold-adapted species such as Gadus morhua and Clupea harengus from some areas around Britain and Ireland, and the establishment of some new, warm-adapted species.

    Global climate change (GCC) is likely to alter the degree of human exposure to pollutants and the response of human populations to these exposures, meaning that risks of pollutants could change in the future. The present study, therefore, explores how GCC might affect the different steps in the pathway from a chemical source in the environment through to impacts on human health and evaluates the implications for existing risk-assessment and management practices. In certain parts of the world, GCC is predicted to increase the level of exposure of many environmental pollutants due to direct and indirect effects on the use patterns and transport and fate of chemicals. Changes in human behavior will also affect how humans come into contact with contaminated air, water, and food. Dietary changes, psychosocial stress, and coexposure to stressors such as high temperatures are likely to increase the vulnerability of humans to chemicals. These changes are likely to have significant implications for current practices for chemical assessment. Assumptions used in current exposure-assessment models may no longer apply, and existing monitoring methods may not be robust enough to detect adverse episodic changes in exposures. Organizations responsible for the assessment and management of health risks of chemicals therefore need to be more proactive and consider the implications of GCC for their procedures and processes.

    The contemporary power sector in the United States is heavily reliant on water resources to provide cooling water for thermoelectric generation. Efficient thermoelectric plant operations require large volumes of water at sufficiently cool temperatures for their cooling process. The total amount of water that is withdrawn or consumed for cooling and any potential declines in efficiencies are determined by the sector's fuel mix and cooling technologies. As such, the impact of climate change, and the extent of impact, on the power sector is shaped by the choice of electricity generation technologies that will be built over the coming decades. In this study, we model potential changes in river discharge and temperature in the contiguous US under a set of climate scenarios to year 2050 using the Water Balance Model-Thermoelectric Power and Thermal Pollution Model (WBM-TP2M). Together, these models quantify, in high-resolution (3-min), river temperatures, discharge and power plant efficiency losses associated with changes in available cooling water that incorporates climate, hydrology, river network dynamics and multi-plant impacts, on both single power plant and regional scales. Results are used to assess the aptness and vulnerability of contemporary and alternative electricity generation pathways to changes in climate and water availability for cooling purposes, and the concomitant impacts on power plant operating efficiencies. We assess the potential impacts by comparing six regions (Northeast, Southeast, Midwest, Great Plains, Southwest, Northwest as in the National Climate Assessment (2014)) across the US. These experiments allow us to assess tradeoffs among electricity-water-climate to provide useful insight for decision-makers managing regional power production and aquatic environments.

    Seasonally dry forests in the neotropics are heavily threatened by a combination of human disturbances and climate change; however, the severity of these threats is seldom contrasted. This study aims to quantify and compare the effects of deforestation and climate change on the natural spatial ranges of 17 characteristic tree species of southern Ecuador dry deciduous forests, which are heavily fragmented and support high levels of endemism as part of the Tumbesian ecoregion. We used 660 plant records to generate species distribution models and land-cover data to project species ranges for two time frames: a simulated deforestation scenario from 2008 to 2014 with native forest to anthropogenic land-use conversion, and an extreme climate change scenario (CCSM4.0, RCP 8.5) for 2050, which assumed zero change from human activities. To assess both potential threats, we compared the estimated annual rates of species loss (i.e., range shifts) affecting each species. Deforestation loss for all species averaged approximately 71 km2/year, while potential climate-attributed loss was almost 21 km2/year. Moreover, annual area loss rates due to deforestation were significantly higher than those attributed to climate-change (P < 0.01). However, projections into the future scenario show evidence of diverging displacement patterns, indicating the potential formation of novel ecosystems, which is consistent with other species assemblage predictions as result of climate change. Furthermore, we provide recommendations for management and conservation, prioritizing the most threatened species such as Albizia multiflora, Ceiba trichistandra, and Cochlospermum vitifolium.

    Full Text Available Abstract Background Pediatric liaison services attending to the psychological health needs of children with chronic physical illness are limited or virtually non-existent in Nigeria and most sub-Saharan African countries, and psychological problems complicate chronic physical illness in these children and their mothers. There exist needs to bring into focus the public health importance of developing liaison services to meet the psychological health needs of children who suffer from chronic physical illness in this environment. Sickle cell disease (SCD and juvenile diabetes mellitus (JDM are among the most common chronic physical health conditions in Nigerian children. This study compared the prevalence and pattern of emotional disorders and suicidal behavior among Nigerian children with SCD, JDM and a group of healthy children. Psychological distress in the mothers of these children that suffer chronic physical illness was also compared with psychological distress in mothers of healthy control children. Methods Forty-five children aged 9 to 17 years were selected for each group of SCD, JDM and controls. The SCD and JDM groups were selected by consecutive clinic attendance and the healthy children who met the inclusion criteria were selected from neighboring schools. The Youth version of the Computerized Diagnostic Interview Schedule for Children, version IV (C- DISC- IV was used to assess for diagnosis of emotional disorders in these children. Twelve-item General Health Questionnaire (GHQ – 12 was used to assess for psychological distress in mothers of these children and healthy control children. Results Children with JDM were significantly more likely to experience DSM – IV emotional disorders than children with SCD and the healthy group (p = 0.005, while children with JDM and SCD were more likely to have 'intermediate diagnoses' of emotional disorders (p = 0.0024. Children with SCD and JDM had higher rates of suicidal ideation when

  17. The Implications of Intermediate Stop Operations on Aviation Emissions and Climate

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Among the various transport modes aviation's impact on climate change deserves special attention. Due to typical flight altitudes in the upper troposphere and above, the effect of aircraft engine emissions like e.g. water vapour, nitrogen oxides and aerosols on radiative forcing agents is substantial. The projected doubling of aircraft movements in the next 15 years will lead to an increase of aviation's impact on climate and requires immediate mitigation options. Besides technological measures also new operational strategies are widely discussed; one of these concepts which has been subject of several studies in the past is Intermediate Stop Operations (ISO. It is based on the idea to reduce the stage length of flights by performing one or more intermediate landings during a mission. Here, we analyse the ISO concept by combining different models, which include a realistic traffic simulation taking into account operational constraints and ambient conditions, like e.g. wind, the calculation of engine emissions and the integration of a climate response model. We analyse the ISO concept for today's worldwide aircraft fleet, including its influence on global emissions distributions as well as the impact on climate change by taking into account CO2 and non-CO2 effects, arising from contrail-cirrus, water vapour and nitrogen oxide emissions. We show in agreement with earlier findings that due to shorter flight distances the amount of fuel burnt over the mission can be reduced by roughly 5 % on average globally. For the first time, we quantify the climate impact of ISO, where the flight trajectory is optimised for fuel use and the aircraft is not redesigned for the ISO procedure. We find an increased warming effect, which arises from nitrogen oxide and water vapour emissions, which are released at higher cruise altitudes and which over-compensate reduced warming effects from CO2 and contrail-cirrus. However, we expect a climate impact reduction for

Trends in climate aridity have been also analysed using UNEP aridity index which is the ratio between rainfall and potential evapotranspiration on a yearly basis. During the examined time period, and particularly in the most recent years, a gradual reduction in rainfall and growing temperatures have been observed which have further widened the gap between precipitation amounts and water demand in agriculture.

    New hydrological insights: The review illustrates some discrepancy among research outputs. For the historical context, this is partially related to the period and length of data analyzed and the failure to consider the influence of multi-decadal oscillations. Consequently, we show that annual cycle of Blue Nile flow has not changed in the past five decades. For the future context, discrepancy is partially attributable to the various and differing climate and hydrological models included and the downscaling techniques applied. The need to prudently consider sources of uncertainty and potential causes of bias in historical trend and climate change impact research is highlighted.

    The timing of phenological parameters such as spring onset and autumn senescence are important controls on the partitioning of water into evaporation and streamflow. Climate largely drives seasonal characteristics of plants and changes in phenological timing can be used to detect the impacts of climate change on water balance controls. However, limited phenological research is available for regions dominated by forest cover such as the central Appalachian Mountains region of the United States. To quantify the impacts of climate change on phenological timing and streamflow in this region, we used GIMMS AVHRR NDVI 13g data from 1982-2012 and the TIMESAT program to extract seasonality parameters. Results show that spring onset has advanced by 9 days, autumn senescence has been delayed by 11 days, and growing season has lengthened by 20 days. Above 500 m elevation, spring onset occurs 2-3 days later; fall senescence arrives 1-2 days earlier, and growing season shortens by 3-5 days. Streamflow has decreased during the growing season over the 31-year study period throughout the region, with the most pronounced effects for the Tennessee River watershed, the southernmost reach of the study area. The elevation patterns are in general agreement with Hopkins law, which states a one-day delay in spring onset for every 30-meter increase in elevation. Streamflow patterns suggest that the southern central Appalachian region is sensitive to changes in climate and are becoming drier, having important implications for drinking water supply, forest ecosystem management, ecosystem services including drinking water supply, and overall forest health.

    2015-12-01

    Fire is a key agent of change in the African savannas, which are shaped through the complex interactions between trees, C4 grasses, rainfall, temperature, CO2 and fire. These fires and their emitted smoke can have numerous direct and indirect effects on the environment, water resources, air quality, and climate. For instance, veld fires in southern Africa cause large financial losses to agriculture, livestock production and forestry on an annual basis. This study contributes to our understanding of the implications of projected surface temperature evolution in Africa for fire risk, human health and agriculture over the coming decades. We use an ensemble of high-resolution regional climate model simulations of African climate for the 21st century. Regional dowscalings and recent global circulation model projections obtained for Africa indicate that African temperatures are likely to rise at 1.5 times the global rate of temperature increase in the tropics, and at almost twice the global rate of increase in the subtropics. Warming is projected to occur during the 21st century, with increases of 4-6 °C over the subtropics and 3-5 °C over the tropics plausible by the end of the century relative to present-day climate under the A2 (low mitigation) scenario. We explore the significance of the projected warming by documenting increases in projected high fire danger days and heat-wave days. General drying is projected across the continent, even for areas (e.g. tropical Africa) where an increase in rainfall is plausible. This is due to the drastic increases in temperature that are projected, which leads to drier soils (through enhanced evaporation) despite the rainfall increases. This will likely impact negatively on crop yield, particularly on the maize crop that is of crucial importance in terms of African food security.

    2016-08-01

    Full Text Available This paper investigates the economic impacts of climate change on cereal crop production in Northern Ghana using 240 households comprising maize and sorghum farmers. The Ricardian regression approach was used to examine the economic impacts of climate change based on data generated from a survey conducted in the 2013/2014 farming seasons. Forty-year time-series data of rainfall and temperature from 1974 to 2013, together with cross-sectional data, were used for the empirical analysis. The Ricardian regression estimates for both maize and sorghum showed varying degrees of climate change impacts on net revenues. The results indicated that early season precipitation was beneficial for sorghum, but harmful for maize. However, mid-season precipitation tended to promote maize production. Temperature levels for all seasons impacted negatively on net revenue for both crops, except during the mid-season, when temperature exerted a positive effect on net revenue for sorghum. Our findings suggest that appropriate adaptation strategies should be promoted to reduce the negative impacts of prevailing climate change on cereal crop production.

    Sustained megadrought events in arid regions pose significant risk to water resources, yet the mechanisms for generating these events remain unclear. A critical question is the degree to which coupled climate models can correctly represent the risk of megadrought; to date, this has been difficult to answer owing to the long timescales of internal variability and the relative rarity of long model simulations. Here, the CESM Last Millennium Ensemble is used to assess the effect of the El Nino/Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), and Atlantic Multidecadal Oscillation (AMO) on megadrought occurrence frequency, intensity, and duration. Megadrought persistence is strongly affected by ENSO amplitude in teleconnected regions such as western North America, southeast Asia, and Australia, via preferential initiation/termination of drought events by strong El Nino/La Nina events. Influences from other modes are less clear although sometimes becoming significant; this implies that correctly representing the relative strength of climate variability could greatly improve model-based megadrought risk estimates. Finally, the effects of climate change-induced shifts in the amplitude of ENSO and other climate modes on future megadrought properties are analyzed using the CESM Large Ensemble.

    Older people account for the highest proportion of mortality from extreme weather events associated with climate change. This article aims to describe the health impacts of climate change on older people. An integrative review was conducted with 30 studies retrieved from PubMed, EBSCO, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) on climate stressors, determinants of resilient capacity, risk factors, and health outcomes. Heat, temperature variability, and air pollution increase mortality risk in older people, especially from cardiovascular and respiratory diseases. Floods are linked with increasing incidence of post-traumatic stress disorder, depression, and anxiety. Facing these adversities, older people exhibit both vulnerability and resilience. Research gaps exist in understanding the full spectrum of the resilience experience of older people, and appreciating areas wherein nursing can play a pivotal role. Recognizing the vulnerabilities of older people in the context of climate change is important. Identifying opportunities to promote resilience is an important focus for nurses to develop tailored and targeted nursing interventions. © 2017 Sigma Theta Tau International.

  12. Changes to the tropical circulation in the mid-Pliocene and their implications for future climate

    Science.gov (United States)

    Corvec, Shawn; Fletcher, Christopher G.

    2017-02-01

    The two components of the tropical overturning circulation, the meridional Hadley circulation (HC) and the zonal Walker circulation (WC), are key to the re-distribution of moisture, heat and mass in the atmosphere. The mid-Pliocene Warm Period (mPWP; ˜ 3.3-3 Ma) is considered a very rough analogue of near-term future climate change, yet changes to the tropical overturning circulations in the mPWP are poorly understood. Here, climate model simulations from the Pliocene Model Intercomparison Project (PlioMIP) are analyzed to show that the tropical overturning circulations in the mPWP were weaker than preindustrial circulations, just as they are projected to be in future climate change. The weakening HC response is consistent with future projections, and its strength is strongly related to the meridional gradient of sea surface warming between the tropical and subtropical oceans. The weakening of the WC is less robust in PlioMIP than in future projections, largely due to inter-model variations in simulated warming of the tropical Indian Ocean (TIO). When the TIO warms faster (slower) than the tropical mean, local upper tropospheric divergence increases (decreases) and the WC weakens less (more). These results provide strong evidence that changes to the tropical overturning circulation in the mPWP and future climate are primarily controlled by zonal (WC) and meridional (HC) gradients in tropical-subtropical sea surface temperatures.

    This article examines the relationships among emotional labour, team climate, burnout, perceived quality of care and turnover intention among nurses in Australia, with the aim of addressing nurse retention and burnout. Emotional labour refers to the regulation of emotion during interpersonal transactions. It may involve faking unfelt emotions, hiding genuine emotions and deep acting whereby the individuals attempt to influence their inner feelings to induce the appropriate outward countenance. Currently, there is a dearth of literature that investigates the link between emotional labour and perceived quality of care and ultimately turnover intention. The contribution of team climate in the relationship between emotional labour and burnout is still uncertain. A cross-sectional quantitative study conducted with self-completed questionnaires. The study was conducted in 2011 with 201 registered nurses. Validated measures were used to measure the aforementioned constructs. Confirmatory factor analyses were used to examine the factor structure of the measured variables and hypotheses were tested using structural equation modelling. The final model demonstrates that faking has a significant negative influence on perceived quality of care. Hiding predicts burnout, leading to an increase in turnover intention. Team climate moderates the relationship between hiding and burnout, which may subsequently influence turnover intention. The establishment of a strong team climate may help nurses to manage the emotional demands of their role, promote their well-being and retention. © 2013 John Wiley & Sons Ltd.

    Some of the most profound and direct impacts of climate change over the next few decades will be on agricultural production and the broader food system. Africa is one of the regions most vulnerable to these impacts due to their under developed economies and the predominance of small farmer, subsistence agriculture. This paper focuses on understanding variations in agricultural production due to rainfall and temperature fluctuations, which are a primary cause of food insecurity on the continent in Africa. A retrospective analysis on the relationship between climate indices and environmental productivity may provide the tools to better manage agricultural investment on the African continent. This paper will present an analysis of the relationship between phenology metrics derived from the 26 year AVHRR NDVI record and the North Atlantic Oscillation index (NAO), the Indian Ocean Dipole (IOD), and the Multivariate ENSO Index (MEI). We explore spatial relationships between agricultural growing conditions as measured by the NDVI and the three climate indices in Eastern, Western and Southern Africa to determine the regions and periods when they have a significant impact. The results show that the start of season and cumulative NDVI were significantly affected by variations in the climate indices. The talk will conclude with analysis which will put these climate-related factors into perspective, as just one element in the overall food security of the region. Agricultural investment policies, the functioning of markets and trade, and an increasing population are at least as important for the food security on the continent. Sustainability of livelihoods will depend both on the ability of vulnerable populations to adapt to changing growing conditions and to compete on the global market for food.

    We applied a mix of observation and empirical models to evaluate both local and global climate effects of three realistic alternative forest management scenarios in the boreal forests of Norway's largest logging region. The alternative management scenarios embraced strategies aimed at increasing harvest intensities and allowing harvested conifer sites to regenerate naturally with broadleaved species. Stand-level analysis was firstly executed to attribute differences in daily, seasonal, and annual mean surface temperatures to differences in surface intrinsic biophysical properties across coniferous, deciduous, and clear-cut sites. Relative to a coniferous site, we observed a slight local cooling of 0.13 °C at a deciduous site and 0.25 °C at a clear-cut site over a 6-year period which was mostly attributed to a higher albedo throughout the year. When monthly mean albedo trajectories over the entire managed forest landscape were taken into consideration, we found that strategies promoting natural regeneration of coniferous sites with native deciduous species led to substantial global direct climate cooling benefits relative to those maintaining current silviculture regimes - despite predicted long-term regional warming feedbacks and a reduced albedo in spring and autumn months. The magnitude and duration of the cooling benefit depended largely on whether management strategies simultaneously promoted an enhanced material supply over business-as-usual levels. While additional climate impact linked to changes in life-cycle emissions and to changes in the global supply and demand of timber products ought to be factored into any mitigation-oriented climate policy involving the forestry sector, our analysis demonstrates that - within the boundaries of the managed forest ecosystem - excluding important biogeophysical considerations like surface albedo change may lead to sub-optimal climate policy.

    There is currently no consensus on the importance of climate change in Mesoamerican prehistory. Some invoke drought as a causal factor in major cultural transitions, including the abandonment of many sites at 900 CE, while others conclude that cultural factors were more important. This lack of agreement reflects the fact that the history of climate change in many regions of Mesoamerica is poorly understood. We present paleolimnological evidence suggesting that climate change was important in the abandonment of Cantona between 900 CE and 1050 CE. At its peak, Cantona was one of the largest cities in pre-Columbian Mesoamerica, with a population of 90,000 inhabitants. The site is located in the Cuenca Oriental, a semiarid basin east of Mexico City. We developed a subcentennial reconstruction of regional climate from a nearby maar lake, Aljojuca. The modern climatology of the region suggests that sediments record changes in summer monsoonal precipitation. Elemental geochemistry (X-ray fluorescence) and δ(18)O from authigenic calcite indicate a centennial-scale arid interval between 500 CE and 1150 CE, overlaid on a long-term drying trend. Comparison of this record to Cantona's chronology suggests that both the city's peak population and its abandonment occurred during this arid period. The human response to climate change most likely resulted from the interplay of environmental and political factors. During earlier periods of Cantona's history, increasing aridity and political unrest may have actually increased the city's importance. However, by 1050 CE, this extended arid period, possibly combined with regional political change, contributed to the city's abandonment.

  8. Ethical implications of co-benefits rationale within climate change mitigation strategy

    Full Text Available Climate change mitigation effort is being translated into several actions and discourses that make collateral benefits and their rationale increasingly relevant for sustainability, in such a way that they are now a constant part of the political agenda. Taking a border and consensual perspective, co-benefits are considered here to be emerging advantages of the implementation of measures regarding the lowering of greenhouse gases.Departing from the analysis of policy documents referring to two European urban transportation strategies, the emergent co-benefits are problematized and discussed to better understand their moral aspect. Further ethical reflection is conducted after an analysis of some unintended consequences of co-benefits rationale coming from the mentioned examples. The focus is primarily on the challenges of an integrative moral justification for co-benefits and also for their role in the climate change mitigation effort. We also discuss the limitations of the current normative models that frame co-benefits rationale, from a moral viewpoint and in relation to the overall climate change mitigation strategy.In this article, we propose the concepts of well-being and freedom, as portrayed by Capabilities Approach, as possible guiding notions for the moral and social evaluation of goodness of these emergent benefits and their rationale too. Additionally, some preliminary conclusions are drawn regarding the potential of the presented concepts to favour the climate change mitigation action. Finally, a scenario is drawn where Capabilities Approach is the moral guideline for co-benefits rationale showing this way its potential in terms of enhancing climate change mitigation strategy.

    The composition of a peatland plant community has considerable effect on a range of ecosystem functions. Peatland plant community structure is predicted to change under future climate change, making the quantification of the direction and magnitude of this change a research priority. We subjected intact, replicated vegetated poor fen peat monoliths to elevated temperatures, increased atmospheric carbon dioxide (CO2 ), and two water table levels in a factorial design to determine the individual and synergistic effects of climate change factors on the poor fen plant community composition. We identify three indicators of a regime shift occurring in our experimental poor fen system under climate change: nonlinear decline of Sphagnum at temperatures 8 °C above ambient conditions, concomitant increases in Carex spp. at temperatures 4 °C above ambient conditions suggesting a weakening of Sphagnum feedbacks on peat accumulation, and increased variance of the plant community composition and pore water pH through time. A temperature increase of +4 °C appeared to be a threshold for increased vascular plant abundance; however the magnitude of change was species dependent. Elevated temperature combined with elevated CO2 had a synergistic effect on large graminoid species abundance, with a 15 times increase as compared to control conditions. Community analyses suggested that the balance between dominant plant species was tipped from Sphagnum to a graminoid-dominated system by the combination of climate change factors. Our findings indicate that changes in peatland plant community composition are likely under future climate change conditions, with a demonstrated shift toward a dominance of graminoid species in poor fens. © 2014 John Wiley & Sons Ltd.

    The Seychelles is a small island state in the western Indian Ocean that is vulnerable to the effects of climate change. This vulnerability led the Intergovernmental Panel on Climate Change (IPCC) in 2001 to express concern over the potential economic and social consequences that may be faced by small island states. Small island states should be prepared to adapt to such changes, especially in view of their dependence on natural resources, such as water and coral reefs, to meet basic human welfare needs. Analysis of long-term data for precipitation, air temperature, and sea-surface temperature indicated that changes are already observable in the Seychelles. The increase in dry spells that resulted in drought conditions in 1999 and the 1998 mass coral bleaching are indicative of the events that are likely to occur under future climate change. Pre-IPCC Third Assessment Report scenarios and the new SRES scenarios are compared for changes in precipitation and air surface temperature for the Seychelles. These intercomparisons indicate that the IS92 scenarios project a much warmer and wetter climate for the Seychelles than do the SRES scenarios. However, a wetter climate does not imply readily available water, but rather longer dry spells with more intense precipitation events. These observations will likely place enormous pressures on water-resources management in the Seychelles. Similarly, sea-surface temperature increases predicted by the HADCm{sup 3} model will likely trigger repeated coral-bleaching episodes, with possible coral extinctions within the Seychelles region by 2040. The cover of many coral reefs around the Seychelles have already changed, and the protection of coral-resilient areas is a critical adaptive option.

    Most reviews concerning the impact of climate change on coral reefs discuss independent effects of warming or ocean acidification. However, the interactions between these, and between these and direct local stressors are less well addressed. This review underlines that coral bleaching, acidification, and diseases are expected to interact synergistically, and will negatively influence survival, growth, reproduction, larval development, settlement, and post-settlement development of corals. Interactions with local stress factors such as pollution, sedimentation, and overfishing are further expected to compound effects of climate change. Reduced coral cover and species composition following coral bleaching events affect coral reef fish community structure, with variable outcomes depending on their habitat dependence and trophic specialisation. Ocean acidification itself impacts fish mainly indirectly through disruption of predation- and habitat-associated behavior changes. Zooxanthellate octocorals on reefs are often overlooked but are substantial occupiers of space; these also are highly susceptible to bleaching but because they tend to be more heterotrophic, climate change impacts mainly manifest in terms of changes in species composition and population structure. Non-calcifying macroalgae are expected to respond positively to ocean acidification and promote microbe-induced coral mortality via the release of dissolved compounds, thus intensifying phase-shifts from coral to macroalgal domination. Adaptation of corals to these consequences of CO2 rise through increased tolerance of corals and successful mutualistic associations between corals and zooxanthellae is likely to be insufficient to match the rate and frequency of the projected changes. Impacts are interactive and magnified, and because there is a limited capacity for corals to adapt to climate change, global targets of carbon emission reductions are insufficient for coral reefs, so lower targets should be

  12. Resource limits and conversion efficiency with implications for climate change and California's energy supply

    Science.gov (United States)

    Croft, Gregory Donald

    There are two commonly-used approaches to modeling the future supply of mineral resources. One is to estimate reserves and compare the result to extraction rates, and the other is to project from historical time series of extraction rates. Perceptions of abundant oil supplies in the Middle East and abundant coal supplies in the United States are based on the former approach. In both of these cases, an approach based on historical production series results in a much smaller resource estimate than aggregate reserve numbers. This difference is not systematic; natural gas production in the United States shows a strong increasing trend even though modest reserve estimates have resulted in three decades of worry about the gas supply. The implication of a future decline in Middle East oil production is that the market for transportation fuels is facing major changes, and that alternative fuels should be analyzed in this light. Because the U.S. holds very large coal reserves, synthesizing liquid hydrocarbons from coal has been suggested as an alternative fuel supply. To assess the potential of this process, one has to look at both the resource base and the net efficiency. The three states with the largest coal production declines in the 1996 to 2006 period are among the top 5 coal reserve holders, suggesting that gross coal reserves are a poor indicator of future production. Of the three categories of coal reserves reported by the U.S. Energy Information Administration, reserves at existing mines is the narrowest category and is approximately the equivalent of proved developed oil reserves. By this measure, Wyoming has the largest coal reserves in the U.S., and it accounted for all of U.S. coal production growth over the 1996 to 2006 time period. In Chapter 2, multi-cycle Hubbert curve analysis of historical data of coal production from 1850 to 2007 demonstrates that U.S. anthracite and bituminous coal are past their production peak. This result contradicts estimates based

  13. Implications of Climate Volatility for Agricultural Commodity Markets in the Presence of Biofuel Mandates

    2011-12-01

    In presence of bio-fuels, link between energy and agricultural commodity markets has become more complex. An increase in ethanol production to minimum 15bn gallons a year - Renewable Fuel Standard (RFS) and current technically permissible maximum 10% blending limit - Blend Wall (BW); make the link even stronger. If oil prices in future do not rise significantly from their current levels, this minimum production requirement would likely be binding. In such a scenario any fluctuation in crop production will have to be absorbed by the non-ethanol usage of the crop and would translate into crop prices adjusting to clear the markets and therefore the commodity prices will be more volatile. At high oil prices it is possible that the BW may become binding, severing the link between oil prices and commodity prices as well, potentially leading to higher price volatility. Hertel and Beckman (2010) find that, with both RFS and BW simultaneously binding, corn price volatility due to supply side shocks (which could arise from extreme climate events) could be more than 50% as large as in the absence of bio-fuel policies. So energy markets are important determinants of agricultural commodity price volatility. This proposal intends to introduce the increased supply side volatility on account of climate change and volatility, in the framework. Global warming on account of increased GHG concentrations is expected to increase the intensity and frequency of hot extremes in US (Diffenbaugh et al. 2008) and therefore affect corn yields. With supply shocks expected to increase, binding RFS and BW will exacerbate the volatility, while if they are non-binding then the price changes could be cushioned. We propose to model the impacts of climate changes and volatility on commodity prices by linking three main components - a. Projections for change in temperature and precipitation using climate model b. A statistical model to predict impacts of change in climate variable on corn yields in US

    Climate change is likely to impact on freshwater ecology, the delivery of regulatory commitments to ecological status and the management of water resources. It is becoming increasingly important for European environment agencies to use and develop methods to aid planning and abstraction licensing procedures and policies in the face of climate change and with the introduction of the Water Framework Directive. Studies have been carried out in the past to investigate the implications of climate change for biodiversity. However, predicting the future is fraught with uncertainty, an area which has not been dealt with in great depth in the past. This study has been undertaken to draw on the results of new methodologies to address the uncertainties inherent in modelling future climate and assess their usability for decision-making in water resources allocations specifically in considering interactions between flow and invertebrate communities The River Itchen was chosen as the case study catchment on the strength of having a long-term coupled ecological and flow dataset and having been an area of intensive study in the past. It is a chalk stream located in the south of England and a candidate Special Area of Conservation. It has also been designated a Special Site of Scientific Interest achieved due to the number of rare species, and the richness of the macro-invertebrate community in the river catchment. An ensemble of 246 transient simulations for future climate was obtained from ClimatePrediction.net which were then used to drive a rainfall-runoff model. In order to link the modelled river flow to ecology, the Lotic Invertebrate Flow Evaluation score has been used where the invertebrate community is linked to flow largely through sensitivity to water velocity and siltation, driven by flow variability at sites with fixed channel dimensions The large ensemble of climate scenarios and thereby flow and ecological indices allows the exploration of the risk of the river of

    Whilst it is agreed that climate change will impact on the long-term interactions between crops and weeds, the results of this impact are far from clear. We suggest that a thorough understanding of weed dominance and weed interactions, depending on crop and weed ecosystems and crop sequences in the ecosystem, will be the key determining factor for successful weed management. Indeed, we claim that recent changes observed throughout the world within the weed spectrum in different cropping systems which were ostensibly related to climate change, warrant a deeper examination of weed vulnerabilities before a full understanding is reached. For example, the uncontrolled establishment of weeds in crops leads to a mixed population, in terms of C3 and C4 pathways, and this poses a considerable level of complexity for weed management. There is a need to include all possible combinations of crops and weeds while studying the impact of climate change on crop-weed competitive interactions, since, from a weed management perspective, C4 weeds would flourish in the increased temperature scenario and pose serious yield penalties. This is particularly alarming as a majority of the most competitive weeds are C4 plants. Although CO2 is considered as a main contributing factor for climate change, a few Australian studies have also predicted differing responses of weed species due to shifts in rainfall patterns. Reduced water availability, due to recurrent and unforeseen droughts, would alter the competitive balance between crops and some weed species, intensifying the crop-weed competition pressure. Although it is recognized that the weed pressure associated with climate change is a significant threat to crop production, either through increased temperatures, rainfall shift, and elevated CO2 levels, the current knowledge of this effect is very sparse. A few models that have attempted to predict these interactions are discussed in this paper, since these models could play an integral

    Full Text Available There are various climate risks that are caused or influenced by climate change. They are known to have a wide range of physical, economic, environmental and social impacts. Apart from damages to the physical environment, many climate risks (climate variability, extreme events and climate-related hazards are associated with a variety of impacts on human well-being, health, and life-supporting systems. These vary from boosting the proliferation of vectors of diseases (e.g., mosquitos, to mental problems triggered by damage to properties and infrastructure. There is a great variety of literature about the strong links between climate change and health, while there is relatively less literature that specifically examines the health impacts of climate risks and extreme events. This paper is an attempt to address this knowledge gap, by compiling eight examples from a set of industrialised and developing countries, where such interactions are described. The policy implications of these phenomena and the lessons learned from the examples provided are summarised. Some suggestions as to how to avert the potential and real health impacts of climate risks are made, hence assisting efforts to adapt to a problem whose impacts affect millions of people around the world. All the examples studied show some degree of vulnerability to climate risks regardless of their socioeconomic status and need to increase resilience against extreme events.

    Using optimal detection techniques with climate model simulations, most of the observed increase of near surface temperatures over the second half of the twentieth century is attributed to anthropogenic influences. However, the partitioning of the anthropogenic influence to individual factors, such as greenhouse gases and aerosols, is much less robust. Differences in how forcing factors are applied, in their radiative influence and in models' climate sensitivities, substantially influence the response patterns. We find standard optimal detection methodologies cannot fully reconcile this response diversity. By selecting a set of experiments to enable the diagnosing of greenhouse gases and the combined influence of other anthropogenic and natural factors, we find robust detections of well mixed greenhouse gases across a large ensemble of models. Of the observed warming over the 20th century of 0.65K/century we find, using a multi model mean not incorporating pattern uncertainty, a well mixed greenhouse gas warm...

    This article presents results of research undertaken to identify factors that affect the vulnerability of rural Mongolian herders to climate change. Findings suggest that models of market development instituted since 1990 have failed to recognize and support key elements of the pastoralist adaptive strategy. A retreating state presence has led to the collapse of regulatory regimes needed to safeguard critical common resources. This in turn has produced considerable social differentiation in the countryside, a breakdown in cooperative institutions, and conflicts over water and pasture. In a context of climate change, these changes seriously threaten the sustainability of the rural economy, leading to livelihood insecurity, growing rural poverty, and increasing rates of migration to shantytowns surrounding the capital city of Ulaanbaatar. The newly vulnerable poor are at higher risk for poor health and malnutrition.

    The available evidence on the impact of climate on human bacterial infections is very limited. We studied the impact of climatic factors on maternal group B streptococci (GBS) colonisation during pregnancy in Barcelona, Spain, in the period 2001-2005. Averages of daily temperature, relative humidity, and heat index (perceived temperature) over weeks 32-36 of gestation, measured by the closest of three meteorological monitors to the maternal place of residence were assigned to each subject. Logistic regression models were developed to extract adjusted odds ratios for continuous and categorical (quartiles) exposures. We detected increased risks of GBS colonisation in higher ambient temperatures and humidity. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

    With increased changes in land cover and global climate, early detection and warning of dust storms in conjunction with effective and widespread information broadcasts will be essential to the prevention and mitigation of future risks and impacts. Human activities, seasonal variations and long-term climatic patterns influence dust storms. More research is needed to analyse these factors of dust mobilisation to create more certainty for the fate of vulnerable populations and ecosystems in the future. Early warning and communication systems, when in place and effectively implemented, can offer some relief to these vulnerable areas. As an issue that affects many regions of the world, there is a profound need to understand the potential changes and ultimately create better early warning systems for dust storms.

    Contents 41 I. 41 II. 42 III. 43 IV. 44 V. 45 Acknowledgements 46 References 46 SUMMARY: Precipitation (PPT) is a primary climatic determinant of plant growth and aboveground net primary production (ANPP) over much of the globe. Thus, PPT-ANPP relationships are important both ecologically and to land-atmosphere models that couple terrestrial vegetation to the global carbon cycle. Empirical PPT-ANPP relationships derived from long-term site-based data are almost always portrayed as linear, but recent evidence has accumulated that is inconsistent with an underlying linear relationship. We review, and then reconcile, these inconsistencies with a nonlinear model that incorporates observed asymmetries in PPT-ANPP relationships. Although data are currently lacking for parameterization, this new model highlights research needs that, when met, will improve our understanding of carbon cycle dynamics, as well as forecasts of ecosystem responses to climate change. © 2016 The Authors.

  8. Implications of polar ocean surface stratification changes on a warming climate

    2017-04-01

    In the North Polar oceans surface properties have a significant influence on regional climate development. Stratification and salinity in this area are not just strongly coupled, they directly affect North Atlantic deepwater production and, thus, the ventilation of the deep sea and global ocean circulation. Besides a direct feedback on surface heat transfer to the Polar North, the response of upper stratification in a crucial region such as the Nordic Seas to near-future hydrologic forcing as surface water in the polar ocean warms and freshens due to global temperature rise and glacier demise, is still largely unresolved. We paired bulk sediment δ15N isotopic signatures with planktic foraminiferal assemblages across three major interglacials, each of which could be viewed as an analogue of the present. The isotope vs. foraminifer comparison defines stratification-induced variations in nitrate utilization between and within all of these warm periods and signifies changes in the thickness of the mixed-layer throughout the previous interglacials. As the thickness directly controls the depth-level of Atlantic water inflow, the changes recorded here suggest that drastic variations in freshwater water input associated with each preceding glacial terminations caused the Atlantic water to flow at greater depth. Backed up by independent salinity reconstructions using hydrogen isotope composition in alkenones, an active involvement of both glacial ice sheet size and subsequent specific melting history on interglacial climate development is suggested. Although the results also call for caution when using older interglacials as future climate analogues, they do help to better understand the effect of freshwater input on climate-sensitive ocean sites. It is further indicated that any future increase in freshwater flux into the polar oceans would not necessarily stop by itself the poleward advection of Atlantic water.

    Empirical models alongside remotely sensed and station measured meteorological observations are employed to investigate both the local and global direct climate change impacts of alternative forest management strategies within a boreal ecosystem of eastern Norway. Stand-level analysis is firstly executed to attribute differences in daily, seasonal, and annual mean surface temperatures to differences in surface intrinsic biophysical properties across conifer, deciduous, and clear-cut sites. Relative to a conifer site, a slight local cooling of −0.13 °C at a deciduous site and −0.25 °C at a clear-cut site were observed over a 6-year period, which were mostly attributed to a higher albedo throughout the year. When monthly mean albedo trajectories over the entire managed forest landscape were taken into consideration, we found that strategies promoting natural regeneration of coniferous sites with native deciduous species led to substantial global direct climate cooling benefits relative to those maintaining current silviculture regimes – despite predicted long-term regional warming feedbacks and a reduced albedo in spring and autumn months. The magnitude and duration of the cooling benefit depended largely on whether management strategies jointly promoted an enhanced material supply over business-as-usual levels. Expressed in terms of an equivalent CO2 emission pulse at the start of the simulation, the net climate response at the end of the 21st century spanned −8 to −159 Tg-CO2-eq., depending on whether near-term harvest levels increased or followed current trends, respectively. This magnitude equates to approximately −20 to −300% of Norway's annual domestic (production) emission impact. Our analysis supports the assertion that a carbon-only focus in the design and implementation of forest management policy in boreal and other climatically similar regions can be counterproductive – and at best – suboptimal if boreal forests are to be used as a

    Various international and national regulations hold polluters liable for the cleanup of released hazardous substances and the restoration/rehabilitation of natural resources to preincident baseline conditions, a process often referred to as natural resource damage assessment and restoration (NRDAR). Here, we, the authors, describe how global climate change (GCC) will challenge each of the steps of NRDAR processes and offer eight recommendations to improve these processes in light of GCC. First, we call for a better understanding of the net effects of GCC and contaminants on natural resources. Second, we urge facilities and environmental managers to plan for GCC-related factors that are expected to increase the probability of contaminant releases. Third, we suggest re-evaluating definitions of baseline and reference conditions given that GCC will alter both their trajectories and variability. Fourth, we encourage long-term monitoring to improve the quantification of baseline conditions that will change as climate changes. This will enhance the accuracy of injury assessments, the effectiveness of restoration, and the detection of early warning signs that ecosystems are approaching tipping points. Fifth, in response to or anticipation of GCC, restoration projects may need to be conducted in areas distant from the site of injury or focused on functionally equivalent natural resources; thus, community involvement in NRDAR processes will be increasingly important. Sixth, we promote using NRDAR restoration projects as opportunities to mitigate GCC-related impacts. Seventh, we recommend adaptive management approaches to NRDAR processes and communication of successes and failures widely. Finally, we recommend focusing on managing the stressors that might be exacerbated by GCC, such as pollution and habitat loss, because there is a long history of successfully mitigating these stressors, which can be more easily managed on local scales than climate change. We believe that

    2014-05-01

    Recent work has greatly increased the number of known glacial oscillations during the last (Otiran) glaciation in South Island, New Zealand. Here we present summary stratigraphic and age results from a tectonic basin in the upper Rangitata Valley and a trough fill in the Rakaia Valley in Canterbury, New Zealand. The deposits constrain a series of intermediate scale glacial advances during OIS 3 that are not recorded in terminal moraine sequences in these valleys. These records demonstrate that ice limits oscillated substantially during the last glacial cycle but that very significant advances occurred at times other than the LGM, with glacial extents 80-95% of the local last glacial maximum. The timings of these advances appear to coincide with fragmentary evidence for glaciation in some other settings in New Zealand and SE Australia, indicating that the advances represent regionally significant climatic events. In the talk, I will summarise the evidence for the better constrained advances, consider the climate forcing required to maintain extended ice in these valleys through much of the last glacial cycle and consider the impact of antecedent ice limits on the climatic conditions at the LGM.

    A Miocene assemblage of fruits and seeds from Mangdan coal mine, Longchuan County, Yunnan Province, southwestern China is reported in this paper. This carpoflora consists of 11 taxa of angiosperms, Corylopsis, Ficus, Hypericum, Lauraceae, Lithoearpus, Magnolia, Myrica, Nyssa, Sabia, Symplocos and Zanthoxylum. The investigation of the nearest living relatives (NLRs) of the 11 taxa suggests that an evergreen broad-leaved forest was growing in Mangdan region in the Miocene. Based on the climatic preferences of the NLRs, the climate at that time was a warm and humid subtropical climate, with the mean annual temperature of 18.8-20.5{sup o}C, the mean temperature of the coldest month was 7.9-11.3{sup o}C, the mean temperature of the warmest month was 27.6-28.0{sup o}C, the difference of temperature of coldest and warmest month was 15.2-17.9{sup o}C, the mean annual precipitation was 1170-1300mm and the relative humidity 70-74%.

    Full Text Available The objective of this questionnaire study was to investigate how Swedish adolescents (n = 321 cope with climate change and how different coping strategies are associated with environmental efficacy, pro-environmental behavior, and subjective well-being. The results were compared to an earlier study on 12-year-olds, and the same coping strategies, problem-focused coping, de-emphasizing the seriousness of the threat, and meaning-focused coping, were identified. As in the study on children, problem-focused and meaning-focused coping were positively related to felt efficacy and environmental behavior, while de-emphasizing the threat was negatively related to these measures. As expected, the more problem-focused coping the adolescents used, the more likely it was that they experienced negative affect in everyday life. This association was explained by the tendency for highly problem-focused adolescents to worry more about climate change. In contrast, meaning-focused coping was positively related to both well-being and optimism. When controlling for well-known predictors such as values and gender, meaning-focused and problem-focused coping were independent positive predictors of environmental efficacy and pro-environmental behavior, while de-emphasizing the threat was a negative predictor of pro-environmental behavior. The results are discussed in relation to coping theories and earlier studies on coping with climate change.

  18. Vertical Velocities in Cumulus Convection: Implications for Climate and Prospects for Realistic Simulation at Cloud Scale

    Science.gov (United States)

    Donner, Leo

    2014-05-01

    Cumulus mass fluxes are essential controls on the interactions between cumulus convection and large-scale flows. Cumulus parameterizations have generally been built around them, and these parameterizations are basic components of climate models. Several important questions in climate science depend also on cumulus vertical velocities. Interactions between aerosols and convection comprise a prominent example, and scale-aware cumulus parameterizations that require explicit information about cumulus areas are another. Basic progress on these problems requires realistic characterization of cumulus vertical velocities from observations and models. Recent deployments of dual-Doppler radars are providing unprecedented observations, which can be compared against cloud-resolving models (CRMs). The CRMs can subsequently be analyzed to develop and evaluate parameterizations of vertical velocities in climate models. Vertical velocities from several cloud models will be compared against observations in this presentation. CRM vertical velocities will be found to depend strongly on model resolution and treatment of sub-grid turbulence and microphysics. Although many current state-of-science CRMs do not simulate vertical velocities well, recent experiments with these models suggest that with appropriate treatments of sub-grid turbulence and microphysics robustly realistic modeling of cumulus vertical velocities is possible.

    Full Text Available Reservoirs are characterized by accumulation of sediments where micropollutants may concentrate, with potential toxic effects on downstream river ecosystems. However, sediment management such as flushing is needed to maintain storage capacity. Climate change is expected to increase sediment loads, but potential effects on their quality are scarcely known. In this context, sediment contamination by trace elements (As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn and organics (Polycyclic Aromatic Hydrocarbons PAHs, Polychlorinated Biphenyls PCBs and C > 12 hydrocarbons was analyzed in 20 reservoirs located in Italian Central Alps. A strong As and a moderate Cd, Hg and Pb enrichment was emphasized by Igeo, with potential ecotoxicological risk according to Probable Effect Concentration quotients. Sedimentation rate, granulometry, total organic carbon (TOC and altitude resulted as the main drivers governing pollutant concentrations in sediments. According to climate change models, expected increase of rainfall erosivity will enhance soil erosion and consequently the sediment flow to reservoirs, potentially increasing coarse grain fractions and thus potentially diluting pollutants. Conversely, increased weathering may enhance metal fluxes to reservoirs. Increased vegetation cover will potentially result in higher TOC concentrations, which may contrast contaminant bioavailability and thus toxicity. Our results may provide elements for a proper management of contaminated sediments in a climate change scenario aiming at preserving water quality and ecosystem functioning.

    The rapid rise in extreme heat events in Australia recently is already taking a health toll. Climate change scenarios predict increases in the frequency and intensity of extreme heat events in the future, and population health may be significantly compromised for people who cannot reduce their heat exposure. Exposure to extreme heat presents a health hazard to all who are physically active, particularly outdoor workers and indoor workers with minimal access to cooling systems while working. At air temperatures close to (or beyond) the core body temperature of 37°C, body cooling via sweating is essential, and this mechanism is hampered by high air humidity. Heat exposure among elite athletes and the military has been investigated, whereas the impacts on workers remain largely unexplored, particularly in relation to future climate change. Workers span all age groups and diverse levels of fitness and health status, including people with higher than "normal" sensitivity to heat. In a hotter world, workers are likely to experience more heat stress and find it increasingly difficult to maintain productivity. Modeling of future climate change in Australia shows a substantial increase in the number of very hot days (>35°C) across the country. In this article, the authors characterize the health risks associated with heat exposure on working people and discuss future exposure risks as temperatures rise. Progress toward developing occupational health and safety guidelines for heat in Australia are summarized.
