    Increasing the capacity of society to make informed climate decisions based on scientific evidence is imperative. While a wide range of education programs and communication efforts to improve understanding and facilitate responsible effective decision-making have been developed in recent years, these efforts have been largely disconnected. The interdisciplinary and trans-disciplinary nature of the problems and potential responses to climate change requires a broad range of expertise and a strategy that overcomes the inherent limitations of isolated programs and efforts. To extend the reach and impact of climate change education and engagement efforts, it is necessary to have a coordination that results in greater collective impact. The Collective Impact model, as described by Kania & Kramer (2011), requires five elements: 1) a common agenda; 2) shared measurement systems; 3) mutually reinforcing activities; 4) continuous communication; and 5) a well-funded backbone support organization. The CLEAN Network has facilitated a series of discussions at six professional meetings from late 2012 through spring 2014 to begin to develop and define the elements of collective impact on climate change education and engagement. These discussions have focused on getting input from the community on a common agenda and what a backbone support organization could do to help extend their reach and impact and enable a longer-term sustainability. These discussions will continue at future meetings, with the focus shifting to developing a common agenda and shared metrics. In this presentation we will summarize the outcomes of these discussions thus far, especially with respect to what activities a backbone support organization might provide to help increase the collective impact of climate change education effort and invite others to join the development of public-private partnership to improve the nations climate literacy. The cumulative input into this evolving discussion on collective

  6. Collective violence caused by climate change and how it threatens health and human rights.

    Science.gov (United States)

    Levy, Barry S; Sidel, Victor W

    2014-06-14

    The weight of scientific evidence indicates that climate change is causally associated with collective violence. This evidence arises from individual studies over wide ranges of time and geographic location, and from two extensive meta-analyses. Complex pathways that underlie this association are not fully understood; however, increased ambient temperatures and extremes of rainfall, with their resultant adverse impacts on the environment and risk factors for violence, appear to play key roles. Collective violence due to climate change poses serious threats to health and human rights, including by causing morbidity and mortality directly and also indirectly by damage to the health-supporting infrastructure of society, forcing people to migrate from their homes and communities, damaging the environment, and diverting human and financial resources. This paper also briefly addresses issues for future research on the relationship between climate change and collective violence, the prevention of collective violence due to climate change, and States' obligations to protect human rights, to prevent collective violence, and to promote and support measures to mitigate and adapt to climate change.

  8. One hundred years: A collective case study of climate change education in Georgia

    Science.gov (United States)

    Bloch, Leonard Mark

    This collective case study examined how five K-12 science teachers taught about climate change during Fall 2013, and asked how the University of Georgia can support climate change education. The participants were all experienced teachers, and included: three high school teachers, a middle school teacher, and an elementary school teacher. 'Postcarbonism', an emerging theoretical framework, shaped the research and guided the analysis. The teachers varied in their teaching practices and in their conceptions of 'climate change', but they were united in: 1) their focus on mitigation over adaptation, and 2) presenting climate change as a remote problem with simple solutions. The teachers drew on varied resources, but in all cases, their most valuable resources were their own skills, knowledge and personality. The University of Georgia can support climate change education by developing locally relevant educational resources. Curriculum developers might consider building upon the work of outstanding teach.

    Since 2012, the Climate and Energy Literacy community have realized that as cities, nations and the international community seek solutions to global climate change over the coming decades, a more comprehensive, interdisciplinary approach to climate literacy—one that includes economic and social considerations—will play a vital role in knowledgeable planning, decision-making, and governance. City, county and state leaders are now leading the American response to a changing climate by incubating social innovation to prevail in the face of unprecedented change. Cities are beginning to realize the importance of critical investments to support the policies and strategies that will foster the climate literacy necessary for citizens to understand the urgency of climate actions and to succeed in a resilient post-carbon economy and develop the related workforce. Over decade of federal and non-profit Climate Change Education effective methods have been developed that can support municipality's significant educational capabilities for the purpose of strengthening and scaling city, state, business, and education actions designed to sustain and effectively address this significant social change. Looking to foster the effective and innovative strategies that will enable their communities several networks have collaborated to identify recommendations for effective education and communication practices when working with different types of audiences. U.S. National Science Foundation funded Climate Change Education Partnership (CCEP) Alliance, the National Wildlife Federation, NOAA Climate Program Office, Tri-Agency Climate Change Education Collaborative and the Climate Literacy and Energy Awareness Network (CLEAN) are working to develop a new web portal that will highlight "effective" practices that includes the acquisition and use of climate change knowledge to inform decision-making. The purpose of the web portal is to transfer effective practice to support communities to be

    Ultimately, effective climate change communication results in a change in behavior, whether the change is individual, household or collective actions within communities. We describe two efforts to promote climate-friendly behavior via climate communication and behavior change theory. Importantly these efforts are designed to scale climate communication principles focused on behavior change rather than soley emphasizing climate knowledge or attitudes. Both cases are embedded in rigorous evaluations (randomized controlled trial and quasi-experimental) of primary and secondary outcomes as well as supplementary analyses that have implications for program refinement and program scaling. In the first case, the Girl Scouts "Girls Learning Environment and Energy" (GLEE) trial is scaling the program via a Massive Open Online Course (MOOC) for Troop Leaders to teach the effective home electricity and food and transportation energy reduction programs. The second case, the Alliance for Climate Education (ACE) Assembly Program, is advancing the already-scaled assembly program by using communication principles to further engage youth and their families and communities (school and local communities) in individual and collective actions. Scaling of each program uses online learning platforms, social media and "behavior practice" videos, mastery practice exercises, virtual feedback and virtual social engagement to advance climate-friendly behavior change. All of these communication practices aim to simulate and advance in-person train-the-trainers technologies.As part of this presentation we outline scaling principles derived from these two climate change communication and behavior change programs.

    Scientific outreach, international networking, collaboration and adequate courses are needed in both developed and developing countries to enable early-career hydrogeologists to promote long-term multidisciplinary approaches to cope with climate-change issues and emphasize the importance of groundwater in a global strategy for adaptation. One such collaboration has involved the Early Career Hydrogeologists' Network of the International Association of Hydrogeologists (ECHN-IAH) and the UNESCO International Hydrological Programme's (IHP) Groundwater Resources Assessment under the Pressures of Humanity and Climate Changes (GRAPHIC) project. This collaboration seeks to foster the education and involvement of the future generation of water leaders in the debate over groundwater and climate change.

    2013-01-01

    Highlights: ► We show development of flood policy frames in context of climate change attention. ► Rising attention on climate change influences traditional flood policy framing. ► The new framing employs global-scale scientific climate change knowledge. ► With declining attention, framing disregards climate change, using local knowledge. ► We conclude that frames function as sensemaking devices selectively using knowledge. -- Abstract: Water management and particularly flood defence have a long history of collective action in low-lying countries like the Netherlands. The uncertain but potentially severe impacts of the recent climate change issue (e.g. sea level rise, extreme river discharges, salinisation) amplify the wicked and controversial character of flood safety policy issues. Policy proposals in this area generally involve drastic infrastructural works and long-term investments. They face the difficult challenge of framing problems and solutions in a publicly acceptable manner in ever changing circumstances. In this paper, we analyse and compare (1) how three key policy proposals publicly frame the flood safety issue, (2) the knowledge referred to in the framing and (3) how these frames are rhetorically connected or disconnected as statements in a long-term conversation. We find that (1) framings of policy proposals differ in the way they depict the importance of climate change, the relevant timeframe and the appropriate governance mode; (2) knowledge is selectively mobilised to underpin the different frames and (3) the frames about these proposals position themselves against the background of the previous proposals through rhetorical connections and disconnections. Finally, we discuss how this analysis hints at the importance of processes of powering and puzzling that lead to particular framings towards the public at different historical junctures

    Full Text Available The Paris Climate Change Conference was successfully concluded with the Paris Agreement, which is a milestone for the world in collectively combating climate change. By participating in IPCC assessments and conducting national climate change assessments, China has been increasing its understanding of the issue. For the first time, China's top leader attended the Conference of the Parties, which indicates the acknowledgement of the rationality and necessity of climate change response by China at different levels. Moreover, this participation reflects China's commitment to including climate change in its ecology improvement program and pursuing a low-carbon society and economy. In order to ensure the success of the Paris Conference, China has contributed significantly. China's constructive participation in global governance shows that China is a responsible power. These principles such as the creation of a future of win–win cooperation with each country contributing to the best of its ability; a future of the rule of law, fairness, and justice; and a future of inclusiveness, mutual learning, and common development will serve as China's guidelines in its efforts to facilitate the implementation of the Paris Agreement and participate in the design of international systems.

    Ngo, A. M.; McNeal, K.; Luginbuhl, S.; Enteen, J.

    2015-12-01

    Climate change is a major environmental issue that is often discussed throughout the world using social media outlets such as Twitter. This research followed and collected tweets about climate change as they related to two events: (i) the June 18, 2015 release of the Encyclical by Pope Francis which included content about climate change and (ii) the upcoming COP21 conference, a United Nations climate change conference, to be held on Dec. 7-8, 2015 in Paris. Using a Twitter account and Ncapture we were able to collect tens of thousands of climate change related tweets that were then loaded into a program called Nvivo which stored the tweets and associated publically available user information. We followed a few major hashtags such as COP21, UNFCCC, @climate, and the Pope. We examined twitter users, the information sources, locations, number of re-tweets, and frequency of tweets as well as the category of the tweet in regard to positive, negative, and neutral positions about climate. Frequency analysis of tweets over a 10 day period of the Encyclical event showed that ~200 tweets per day were made prior to the event, with ~1000 made on the day of the event, and ~100 per day following the event. For the COP21 event, activity ranged from 2000-3000 tweets per day. For the Encyclical event, an analysis of 1100 tweets on the day of release indicated that 47% of the tweets had a positive perspective about climate change, 50% were neutral, 1% negative, and 2% were unclear. For the COP21 event, an analysis of 342 tweets randomly sampled from 31,721 tweets, showed that 53% of the tweets had a positive perspective about climate change, 12% were neutral, 13% negative, and 22% were unclear. Differences in the frequency and perspectives of tweets were likely due to the nature of the events, one a long-term and recurring international event and the other a single international religious-oriented event. We tabulated the top 10 tweets about climate change as they relate to these two

    Climate is traditionally one of the main fields of research interest and objects for study in Bulgaria. Therefore, many investigations on its genesis and specific features are carried out in the past and present. Recently, climate change research appears to be the most actual topic and it is in the centre of climatic studies. A major part of these studies are realized at the National Institute of Meteorology and Hydrology (NIMH) because of its essential role in collection and analysis of the basic climatic data for the country. A brief description of the climate change research at NIMH is presented and the obtained results are summarized

    The Climate Data Initiative (CDI) is a broad multi-agency effort of the U.S. government that seeks to leverage the extensive existing federal climate-relevant data to stimulate innovation and private-sector entrepreneurship to support national climate-change preparedness. The CDI project is a systematic effort to manually curate and share openly available climate data from various federal agencies. To date, the CDI has curated seven themes, or topics, relevant to climate change resiliency. These themes include Coastal Flooding, Food Resilience, Water, Ecosystem Vulnerability, Human Health, Energy Infrastructure, and Transportation. Each theme was curated by subject matter experts who selected datasets relevant to the topic at hand. An analysis of the entire Climate Data Initiative data collection and the data curated for each theme offers insights into which datasets are considered most relevant in addressing climate resiliency. Other aspects of the data collection will be examined including which datasets were the most visited or popular and which datasets were the most sought after for curation by the theme teams. Results from the analysis of the CDI collection will be presented in this talk.

    2004-07-01

    This book explains the nature of climate change, the options to respond to it and the virtues of Canada's commitment to the Kyoto Protocol. It includes a collection of essays by prominent Canadian scientists and scholars who discuss the impacts of climate change on Canada from physical, social, technological, economic and political perspectives. Climate change assessments have been made possible by monitoring and recording changes in atmospheric concentrations of greenhouse gases. As a result of these assessments, climate change has become an issue on policy agendas. Advanced computer models have convinced much of the scientific community that climate change will bring with it droughts, floods, hurricanes, forest fires, ice storms, blackouts, and increased warming in countries in high latitudes, including Canada, despite remaining uncertainties about how human activities will affect the climate. The authors cautioned that climate change response strategies can only be refined once these uncertainties are significantly reduced. refs., tabs., figs.

    2014-04-01

    One manifestation of climate change is the increasingly severe extreme weather that causes injury, illness and death through heat stress, air pollution, infectious disease and other means. Leading health organisations around the world are responding to the related water and food shortages and volatility of energy and agriculture prices that threaten health and health economics. Environmental and climate ethics highlight the associated challenges to human rights and distributive justice but rarely address health or encompass bioethical methods or analyses. Public health ethics and its broader umbrella, bioethics, remain relatively silent on climate change. Meanwhile global population growth creates more people who aspire to Western lifestyles and unrestrained socioeconomic growth. Fulfilling these aspirations generates more emissions; worsens climate change; and undermines virtues and values that engender appreciation of, and protections for, natural resources. Greater understanding of how virtues and values are evolving in different contexts, and the associated consequences, might nudge the individual and collective priorities that inform public policy toward embracing stewardship and responsibility for environmental resources necessary to health. Instead of neglecting climate change and related policy, public health ethics and bioethics should explore these issues; bring transparency to the tradeoffs that permit emissions to continue at current rates; and offer deeper understanding about what is at stake and what it means to live a good life in today's world.

    Anthropogenic climate change is predicted to be a major cause of species extinctions in the next 100 years. But what will actually cause these extinctions? For example, will it be limited physiological tolerance to high temperatures, changing biotic interactions or other factors? Here, we systematically review the proximate causes of climate-change related extinctions and their empirical support. We find 136 case studies of climatic impacts that are potentially relevant to this topic. However, only seven identified proximate causes of demonstrated local extinctions due to anthropogenic climate change. Among these seven studies, the proximate causes vary widely. Surprisingly, none show a straightforward relationship between local extinction and limited tolerances to high temperature. Instead, many studies implicate species interactions as an important proximate cause, especially decreases in food availability. We find very similar patterns in studies showing decreases in abundance associated with climate change, and in those studies showing impacts of climatic oscillations. Collectively, these results highlight our disturbingly limited knowledge of this crucial issue but also support the idea that changing species interactions are an important cause of documented population declines and extinctions related to climate change. Finally, we briefly outline general research strategies for identifying these proximate causes in future studies.

  8. Weather anomalies affect Climate Change microblogging intensity

    Molodtsova, T.; Kirilenko, A.

    2012-12-01

    There is a huge gap between the scientific consensus and public understanding of climate change. Climate change has become a political issue and a "hot" topic in mass media that only adds the complexity to forming the public opinion. Scientists operate in scientific terms, not necessarily understandable by general public, while it is common for people to perceive the latest weather anomaly as an evidence of climate change. In 1998 Hansen et al. introduced a concept of an objectively measured subjective climate change indicator, which can relate public feeling that the climate is changing to the observed meteorological parameters. We tested this concept in a simple example of a temperature-based index, which we related to microblogging activity. Microblogging is a new form of communication in which the users describe their current status in short Internet messages. Twitter (http://twitter.com), is currently the most popular microblogging platform. There are multiple reasons, why this data is particularly valuable to the researches interested in social dynamics: microblogging is widely used to publicize one's opinion with the public; has broad, diverse audience, represented by users from many countries speaking different languages; finally, Twitter contains an enormous number of data, e.g., there were 1,284,579 messages related to climate change from 585,168 users in the January-May data collection. We collected the textual data entries, containing words "climate change" or "global warming" from the 1st of January, 2012. The data was retrieved from the Internet every 20 minutes using a specially developed Python code. Using geolocational information, blog entries originating from the New York urbanized area were selected. These entries, used as a source of public opinion on climate change, were related to the surface temperature, obtained from La Guardia airport meteorological station. We defined the "significant change" in the temperature index as deviation of the

    As the effects of climate change become more profound, climate literacy becomes increasingly important. The American Meteorological Society (AMS) responds to this need through the publication of Our Changing Climate and Living With Our Changing Climate. Both publications incorporate the latest scientific understandings of Earth's climate system from reports such as IPCC AR5 and the USGCRP's Third National Climate Assessment. Topic In Depth sections appear throughout each chapter and lead to more extensive, multidisciplinary information related to various topics. Additionally, each chapter closes with a For Further Exploration essay, which addresses specific topics that complement a chapter concept. Web Resources, which encourage additional exploration of chapter content, and Scientific Literature, from which chapter content was derived can also be found at the conclusion of each chapter. Our Changing Climate covers a breadth of topics, including the scientific principles that govern Earth's climate system and basic statistics and geospatial tools used to investigate the system. Released in fall 2015, Living With Our Changing Climate takes a more narrow approach and investigates human and ecosystem vulnerabilities to climate change, the role of energy choices in affecting climate, actions humans can take through adaption, mitigation, and policy to lessen vulnerabilities, and psychological and financial reasons behind climate change denial. While Living With Our Changing Climate is intended for programs looking to add a climate element into their curriculum, Our Changing Climate is part of the AMS Climate Studies course. In a 2015 survey of California University of Pennsylvania undergraduate students using Our Changing Climate, 82% found it comfortable to read and utilized its interactive components and resources. Both ebooks illuminate the multidisciplinary aspect of climate change, providing the opportunity for a more sustainable future.

  10. iSeeChange: Crowdsourced Climate Change Reporting

    2012-12-01

    Directly engaging local communities about their climate change experiences has never been more important. As weather and climate become more unpredictable, these experiences provide a baseline for community decisions, developing adaptation strategies, and planning for the future. Typically, climate change is documented in a top-down fashion: a scientist has a question, makes observations, and publishes a study; in the best case scenario, a journalist reports on the results; if there's time, a local anecdote is sought to put the results in a familiar context. iSeeChange, a public media project funded by the Corporation for Public Broadcasting, reports local environmental change in reverse and turns community questions and conversations with scientists into reported stories that promote opportunities to learn about climate change's affects on the environment and daily life. iSeeChange engages residents of the North Fork Valley region of western Colorado in a multiplatform conversation with scientists about how they perceive their environment is changing through the course of a year - season to season. By bringing together public radio, a mobile reporting and cellular engagement strategy, and a custom crowdsourcing multimedia platform, iSeeChange provides a central access point to collect observations (texts, photographs, voice recordings, and video), organize conversations and interviews with scientists, and report stories online and on air. In this way, iSeeChange is building a dynamic crowdsourced reservoir of information that can increase awareness of environmental problems and potentially disseminate useful information about climate change and successful adaptation strategies. Ultimately, by understanding the community's information needs in a localized question-driven context, the iSeeChange platform presents opportunities for the science community to better understand the value of information and develop better ways to tailor information for communities to use

    In this paper, the authors discuss in brief the magnitude and rate of past changes in climate and examine the various factors influencing climate in order to place the potential warming due to increasing greenhouse gas concentrations in context. Feedback mechanisms that can amplify or lessen imposed climate changes are discussed next. The overall sensitivity of climate to changes in forcing is then considered, followed by a discussion of the time-dependent response of the Earth system. The focus is on global temperature as an indicator for the magnitude of climatic change

  14. Knowledge and passive adaptation to climate change: An example from Indian farmers

    Full Text Available This study is an attempt to use group information collected on climate change from farmers in eastern Uttar Pradesh, India to address a key question related to climate change policy: How to encourage farmers to adapt to climate change? First, we investigate farmers’ perception of and adaptation to climate change using content analysis and group information. The findings are then compared with climatic and agriculture information collected through secondary sources. Results suggest that though farmers are aware of long-term changes in climatic factors (temperature and rainfall, for example, they are unable to identify these changes as climate change. Farmers are also aware of risks generated by climate variability and extreme climatic events. However, farmers are not taking concrete steps in dealing with perceived climatic changes, although we find out that farmers are changing their agricultural and farming practices. These included changing sowing and harvesting timing, cultivation of crops of short duration varieties, inter-cropping, changing cropping pattern, investment in irrigation, and agroforestry. Note that these changes may be considered as passive response or adaptation strategies to climate change. Perhaps farmers are implicitly taking initiatives to adapt climate change. Finally, the paper suggests some policy interventions to scale up adaptation to climate change in Indian agriculture.

    This paper presents the effects of climate change relevant for Denmark, including the change in mean year values as well as the extent of maximum and minimum extremes. Described by the Intergovernmental Panel on Climate Change, the assumptions that the scenarios are based on were outlined...... and evaluated in a Danish context. The uncertainty of the scenarios leaves major challenges that, if not addressed and taken into account in building design, will grow far more serious as climate change progresses. Cases implemented in the Danish building stock illustrate adaptation to climate change...... and illustrate how building design can include mitigating measures to counteract climate change. Cases studied were individual buildings as well as the urban environment. Furthermore the paper describes some of the issues that must be addressed, as the building sector is investing in measures to adapt to climate...

  17. On the Commons and Climate Change: Collective Action and GHG Mitigation - Working Paper No. 2012-13

    International Nuclear Information System (INIS)

    Cochran, Ian

    2012-07-01

    Reducing greenhouse-gas (GHG) emissions from anthropogenic activity may be one of the greatest collective-action problems faced by humanity. This poses challenges not only in terms of the institutional configurations to support coordinated governance processes, but equally the information tools and expertise necessary to link GHG mitigation with other policy priorities. This paper theoretically explores how the adoption of a modified theory of collective action based upon a behavioral theory of the individual allows for a re-framing of the climate-change policy challenge. As such, it appears important to develop a context within which collective action becomes possible where success is no longer solely tied to incentives, but equally to the provision of information, learning, and interaction between stakeholders while simultaneously fostering trust and reciprocity among actors. At all levels of government, information plays a key role to both inform and to facilitate communication, as well as to identify and develop the necessary actions and investments and to track changes in conditions. In the case of climate change, greenhouse-gas inventories and other informational tools are necessary components to track an a priori intangible emission. As such, it is key to analyze the legitimacy, credibility and saliency of information and expertise integrated into the decision-making process. Further, it is important to recognize that the construction of indicators and other information tools is not apolitical, but rather the product of a number of assumptions, interests and decisions concerning what is included and what is excluded shaped by the involved actors.

    Earth's Critical Zone extends from the top of the tree canopy to the base of the groundwater lens. Thus the Critical Zone is examined as a suite of interconnected systems and study of the CZ is inherently interdisciplinary. Climate change is an important driver of CZ processes. The US Critical Zone Observatory Network comprises nine observatories and a coordinating National Office. Educational programs and materials developed at each CZO and the National Office have been collected, reviewed, and presented on-line at the CZONO (criticalzone.org/national/education-outreach/resources). Because the CZOs are designed to observe and measure a suite of common parameters on varying geological substrates and within different ecological contexts, educational resources reflect the diversity of processes represented across the network. As climate change has a network-wide impact, the fundamental building blocks of climate change literacy are key elements in many activities within the CZONO resource collection. Carbon-cycle and hydrologic cycle processes are well-represented, with emphasis on human interactions with these resources, as well as the impact of extreme events and the changing climate. Current work on the resource collection focuses on connecting individual resources to "Teach Climate Science" project and the Teacher-Friendly Guide to Climate Change (teachclimatescience.wordpress.com). The Teacher-Friendly Guide is a manual for K-12 teachers that presents both the fundamentals of climate science alongside resources for effective teaching of this controversial topic. Using the reach of the CZO network we hope to disseminate effective climate literacy resources and support to the K-12 community.

    Mitigation of climate change is often described as a tragedy of the commons. According to this theoretical framework, it is collectively rational for present-generation countries to mitigate climate change, but not individually rational to do so. It is rather in national self-interest to ‘free-ride’ on the mitigation actions of other countries. In this paper, I discuss two arguments criticizing this view. According to these arguments, it is in most cases individually rational for present-gene...

    Global climate change and its impact on public health exemplify the challenge of managing complexity and uncertainty in health research. The Canadian North is currently experiencing dramatic shifts in climate, resulting in environmental changes which impact Inuit livelihoods, cultural practices, and health. For researchers investigating potential climate change impacts on Inuit health, it has become clear that comprehensive and meaningful research outcomes depend on taking a systemic and transdisciplinary approach that engages local citizens in project design, data collection, and analysis. While it is increasingly recognised that using approaches that embrace complexity is a necessity in public health, mobilizing such approaches from theory into practice can be challenging. In 2009, the Rigolet Inuit Community Government in Rigolet, Nunatsiavut, Canada partnered with a transdisciplinary team of researchers, health practitioners, and community storytelling facilitators to create the Changing Climate, Changing Health, Changing Stories project, aimed at developing a multi-media participatory, community-run methodological strategy to gather locally appropriate and meaningful data to explore climate-health relationships. The goal of this profile paper is to describe how an EcoHealth approach guided by principles of transdisciplinarity, community participation, and social equity was used to plan and implement this climate-health research project. An overview of the project, including project development, research methods, project outcomes to date, and challenges encountered, is presented. Though introduced in this one case study, the processes, methods, and lessons learned are broadly applicable to researchers and communities interested in implementing EcoHealth approaches in community-based research.

  3. Utilizing the social media data to validate 'climate change' indices

    2013-12-01

    Reporting the observed and modeled changes in climate to public requires the measures understandable by the general audience. E.g., the NASA GISS Common Sense Climate Index (Hansen et al., 1998) reports the change in climate based on six practically observable parameters such as the air temperature exceeding the norm by one standard deviation. The utility of the constructed indices for reporting climate change depends, however, on an assumption that the selected parameters are felt and connected with the changing climate by a non-expert, which needs to be validated. Dynamic discussion of climate change issues in social media may provide data for this validation. We connected the intensity of public discussion of climate change in social networks with regional weather variations for the territory of the USA. We collected the entire 2012 population of Twitter microblogging activity on climate change topic, accumulating over 1.8 million separate records (tweets) globally. We identified the geographic location of the tweets and associated the daily and weekly intensity of twitting with the following parameters of weather for these locations: temperature anomalies, 'hot' temperature anomalies, 'cold' temperature anomalies, heavy rain/snow events. To account for non-weather related events we included the articles on climate change from the 'prestige press', a collection of major newspapers. We found that the regional changes in parameters of weather significantly affect the number of tweets published on climate change. This effect, however, is short-lived and varies throughout the country. We found that in different locations different weather parameters had the most significant effect on climate change microblogging activity. Overall 'hot' temperature anomalies had significant influence on climate change twitting intensity.

The main objective of the research is to predict the quantity of selected forest fruits depending on the different climate change scenarios (A1Bmin, A1Bmax, A2min and A2max. The general (modeling method, basic (dialectical and specific scientific methods (induction and deduction, analysis and synthesis, abstraction and concretization were used. Regression models were used in data processing, where the focus was on the statistical significance of the correlation coefficient in relation to the statistical significance of the parameters. The research found that, in the coming period, with the increase in temperature and precipitation, an increase in the collected amount of wild strawberries and blueberries could be expected, and the decline of juniper. Longer-term forecasts indicate expected growth with wild strawberries and blueberries with a tendency to slow down after 2040, and expected decline with juniper, with the same slow down tendency after 2040.

    More than 1000 prominent representatives from science, industry, politics and NGOs were gathered in Aarhus on 5-7 March 2009 for the international climate conference 'Beyond Kyoto: Addressing the Challenges of Climate Change'. Thematically, Beyond Kyoto was divided into seven areas of particular interest for understanding the effects of the projected future climate change and how the foreseen negative impacts can be counteracted by mitigation and adaptation measures. The themes were: Climate policy: the role of law and economics; Biodiversity and ecosystems; Agriculture and climate change; Nanotechnology solutions for a sustainable future; Citizens and society, and The Arctic. The main responsible scientists for the seven conference themes and representatives from the think-tank CONCITO delivered 'The 7 Aarhus Statements on Climate Change' as part of the closing session of the conference. The statements were also communicated to the Danish Government as well as to the press. This article is the product of the collective subsequent work of the seven theme responsibles and is a presentation of each theme statement in detail, emphasizing the current state of knowledge and how it may be used to minimize the expected negative impacts of future climate change.

    Climate change (including climate variability) refers to regional or global changes in mean climate state or in patterns of climate variability over decades to millions of years often identified using statistical methods and sometimes referred to as changes in long-term weather conditions (IPCC, 2012). Climate is influenced by changes in continent-ocean configurations due to plate tectonic processes, variations in Earth’s orbit, axial tilt and precession, atmospheric greenhouse gas (GHG) concentrations, solar variability, volcanism, internal variability resulting from interactions between the atmosphere, oceans and ice (glaciers, small ice caps, ice sheets, and sea ice), and anthropogenic activities such as greenhouse gas emissions and land use and their effects on carbon cycling.

    Changes of variability with climate change are likely to have a substantial impact on vegetation and society, rivaling the importance of changes in the mean values themselves. A variety of paleoclimate and future climate simulations performed with the GISS global climate model is used to assess how the variabilities of temperature and precipitation are altered as climate warms or cools. In general, as climate warms, temperature variability decreases due to reductions in the latitudinal temperature gradient and precipitation variability increases together with the intensity of the hydrologic cycle. If future climate projections are accurate, the reduction in temperature variability will be minimized by the rapid change in mean temperatures, but the hydrologic variability will be amplified by increased evapotranspiration. Greater hydrologic variability would appear to pose a potentially severe problem for the next century

    Cities rather than national governments take the lead in acting on climate change. Several cities have voluntarily created climate change plans to prevent and prepare for the effects of climate change. In the literature climate change has been examined as a multilevel governance area taking place...... around international networks. Despite the many initiatives taken by cities, existing research shows that the implementation of climate change actions is lacking. The reasons for this scarcity in practice are limited to general explanations in the literature, and studies focused on explaining...... the constraints on climate change planning at the local level are absent. To understand these constraints, this PhD thesis investigates the institutional dynamics that influence the process of the integration of climate change into planning practices at the local level in Denmark.

    Full Text Available Climate changes have a strong negative impact on the insurance sector, which is reflected in the slow development of the insurance sector and in the transfer of the greater part of risk on the state and individuals. The difference between collected and paid premiums on the basis of incurred losses is rapidly decreasing, which leads to the fact that insurance market is less and less capable of absorbing the losses associated with climate changes, which then has negative repercussions on the availability of insurance services at an affordable premium. The question of establishing potential long and short-term effects of climate changes on business activities of insurance and reinsurance companies represents a priority and its ultimate objective is to find ways to minimize risks and losses. The problem of climate changes represents an important social problem in today’s civilization. At the same time, it is also an ecological problem, but also economic, political, social, cultural, health, etc. It is a global ecological problem, hence we can speak about global climate changes which affect states, nations, continents regardless of where they are and how responsible they are for creating and sustaining these changes.

    This book provides a fresh and innovative perspective on climate change policy. By emphasizing the multiple facets of climate policy, from mitigation to adaptation, from technological innovation and diffusion to governance issues, it contains a comprehensive overview of the economic and policy dimensions of the climate problem. The keyword of the book is balance. The book clarifies that climate change cannot be controlled by sacrificing economic growth and many other urgent global issues. At the same time, action to control climate change cannot be delayed, even though gradually implemented. Therefore, on the one hand climate policy becomes pervasive and affects all dimensions of international policy. On the other hand, climate policy cannot be too ambitious: a balanced approach between mitigation and adaptation, between economic growth and resource management, between short term development efforts and long term innovation investments, should be adopted. I recommend its reading. Carlo Carraro, President, Ca�...

This article performs a meta-analysis of three popular climate change films, The Day after Tomorrow (2005), An Inconvenient Truth (2006), and The Age of Stupid (2009), drawing on research in social psychology, human agency, and media effect theory in order to formulate a rationale about how mass media communication shapes our everyday life experience. This article highlights the factors with which science blends in the reception of the three climate change films and expands the range of options considered in order to encourage people to engage in climate change mitigation actions. © The Author(s) 2014.

    Refugia have long been studied from paleontological and biogeographical perspectives to understand how populations persisted during past periods of unfavorable climate. Recently, researchers have applied the idea to contemporary landscapes to identify climate change refugia, here defined as areas relatively buffered from contemporary climate change over time that enable persistence of valued physical, ecological, and socio-cultural resources. We differentiate historical and contemporary views, and characterize physical and ecological processes that create and maintain climate change refugia. We then delineate how refugia can fit into existing decision support frameworks for climate adaptation and describe seven steps for managing them. Finally, we identify challenges and opportunities for operationalizing the concept of climate change refugia. Managing climate change refugia can be an important option for conservation in the face of ongoing climate change. PMID:27509088

    The climate issue is a great political and scientific challenge for several reasons: (1) There are many uncertain aspects of the climate problem, such as future emission of climate gases, the response of the climate system upon these gases, and the effects of climate changes. (2) It is probable, however, that anthropogenic emission of climate gases, deforestation etc. will cause noticeable climate changes in the future. This might be observed as increased frequency of extreme weather situations. This appears to be a greater threat than a gradual increase of temperature and precipitation. (3) Since the climate system is large and react only relatively slowly on changes in for instance the emission of climate gases, the climate problem can only be solved by means of long-term measures. (4) The climate changes may be irreversible. A rational short-term strategy is to ensure maximum flexibility, which can be done by ''slowing down'' (curtailing emissions) and by avoiding irreversible actions as much as possible. The long-term challenge is to develop an economically responsible alternative to the present fossil-based energy system that permits carbon-efficient technologies to compete on price with coal and unconventional oil and gas. Norway is in a special position by being a large exporter of fossil fuel and at the same time wanting to appear responsible in environmental matters. This combination may incur considerable expenses upon Norway and it is therefore important that environmental commitments like the Kyoto agreement can be honoured to the lowest possible cost. The costs can be minimized by: (1) minimizing the measure costs in Norway, (2) working to make the international quota price as low as possible, and (3) reducing the loss of petroleum income as much as possible. This report describes the earth's climate history, the forces behind climatic changes and what the prospects for the future look like. It also reviews what is being done to curtail the emission of

  3. Imaginary politics: Climate change and making the future

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available Climate change places major transformational demands on modern societies. Transformations require the capacity to collectively envision and meaningfully debate realistic and desirable futures. Without such a collective imagination capacity and active deliberation processes, societies lack both the motivation for change and guidance for decision-making in a certain direction of change. Recent arguments that science fiction can play a role in societal transformation processes is not yet supported by theory or empirical evidence. Advancing the argument that fiction can support sustainability transformations, this paper makes four contributions. First, building on the imaginary concept, I introduce and define the idea of socio-climatic imaginaries. Second, I develop a theory of imagination as linked cognitive-social processes that enable the creation of collectively shared visions of future states of the world. This theory addresses the dynamics that bridge imagination processes in the individual mind and collective imagining that informs social and political decision-making. Third, emphasizing the political nature of creating and contesting imaginaries in a society, I introduce the role of power and agency in this theory of collective imagination. I argue that both ideational and structural power concepts are relevant for understanding the potential societal influence of climate fiction. Finally, the paper illuminates these different forms of transformational power and agency with two brief case studies: two climate fiction novels. I contrast a dystopian and utopian science fiction novel – Paolo Bacigalupi’s The Water Knife (2015 and Kim Stanley Robinson's Green Earth (2015. The two books are very similar in their power/agency profile, but the comparison provides initial insights into the different roles of optimistic and pessimistic future visions.

  4. The origin of climate changes.

    Investigation on climate change is coordinated by the Intergovernmental Panel on Climate Change (IPCC), which has the delicate task of collecting recent knowledge on climate change and the related impacts of the observed changes, and then developing a consensus statement from these findings. The IPCC's last review, published at the end of 2007, summarised major findings on the present climate situation. The observations show a clear increase in the temperature of the Earth's surface and the oceans, a reduction in the land snow cover, and melting of the sea ice and glaciers. Numerical modelling combined with statistical analysis has shown that this warming trend is very likely the signature of increasing emissions of greenhouse gases linked with human activities. Given the continuing social and economic development around the world, the IPCC emission scenarios forecast an increasing greenhouse effect, at least until 2050 according to the most optimistic models. The model ensemble predicts a rising temperature that will reach dangerous levels for the biosphere and ecosystems within this century. Hydrological systems and the potential significant impacts of these systems on the environment are also discussed. Facing this challenging future, societies must take measures to reduce emissions and work on adapting to an inexorably changing environment. Present knowledge is sufficientto start taking action, but a stronger foundation is needed to ensure that pertinent long-term choices are made that will meet the demands of an interactive and rapidly evolving world.

    Received ideas about climatic change are a mixture of right and wrong information. The authors use these ideas as starting points to shade light on what we really know and what we believe to know. The book is divided in three main chapters: should we act in front of climatic change? How can we efficiently act? How can we equitably act? For each chapter a series of received ideas is analyzed in order to find those which can usefully contribute to mitigate the environmental, economical and social impacts of climatic change. (J.S.)

    After an introduction and an interview with an historian on the Little Ice Age of the 17. century, this collective book gathers several contributions. A first set discusses the possible change of capitalism under the influence of the carbon market. The authors discuss the political economy of global warming, the relationship between climate negotiation and carbon price, the ways companies take the carbon price into account in their decisions, and the energy and economic transitions. The second set of contributions discusses the influence of climate on the logics of political choices. The authors address the relationship between natural resources and growth, the macro-economic consequences of climate disruption, how to finance the climate, the virtuous relationships between finance and climate, and why it seems so difficult to act for the climate when considering political ambition and economic lucidity. The third and last set of contributions addresses the possible influence of climate change on geopolitics. The authors address and comment the situation of southern countries with respect to climate change, the American leadership challenged by climate issues, the threat China could be for climate more than for anything else, and the European energy strategy with respect to the COP21. A last article discusses the relationship between global warming and the evolution of the Arctic area

  7. Beyond Wiki to Judgewiki for Transparent Climate Change Decisions

    2008-12-01

    Climate Change is like the prisoner's dilemma, a zero-sum game, or cheating in sports. Everyone and every country is tempted to selfishly maintain or advance their standard of living. The tremendous difference between standards of living amplifies the desire to opt out of Climate Change solutions adverse to economic competitiveness. Climate Change is also exceedingly complex. No one person, one organization, one country, or partial collection of countries has the capacity and the global support needed to make decisions on Climate Change solutions. There are thousands of potential actions, tens of thousands of known and unknown environmental and economic impacts. Some actions are belatedly found to be unsustainable beyond token volumes, corn ethanol or soy-biodiesel for example. Mankind can address human nature and complexity with a globally transparent information and decision process available to all 7 billion of us. We need a process that builds trust and simplifies complexity. Fortunately, we have the Internet for trust building communication and computers to simplify complexity. Mankind can produce new software tailored to the challenge. We would combine group information collection software (a wiki) with a decision-matrix (a judge), market forecasting, and video games to produce the tool mankind needs for trust building transparent decisions on Climate Change actions. The resulting software would be a judgewiki.

    Climate change is a cause for concern both globally and locally. In order for it to be tackled holistically, its governance is an important topic needing scientific and practical consideration. Climate change governance is an emerging area, and one which is closely related to state and public administrative systems and the behaviour of private actors, including the business sector, as well as the civil society and non-governmental organisations. Questions of climate change governance deal both with mitigation and adaptation whilst at the same time trying to devise effective ways of managing the consequences of these measures across the different sectors. Many books have been produced on general matters related to climate change, such as climate modelling, temperature variations, sea level rise, but, to date, very few publications have addressed the political, economic and social elements of climate change and their links with governance. This book will address this gap. Furthermore, a particular feature of this book is that it not only presents different perspectives on climate change governance, but it also introduces theoretical approaches and brings these together with practical examples which show how main principles may be implemented in practice.

    Abstract Climate change mitigation constitutes a social dilemma, a conflict between personal and collective outcomes. Behaviours that result in personal benefits (e.g. travelling quickly, conveniently and cheaply by plane) also result in a collective cost in the form of climate change. Behavioural theories and evidence suggest this social dilemma structure significantly influences behaviour. This thesis aims to understand how the social dilemma structure of climate change mitigation affect...

    Risk-based planning offers a robust way to identify strategies that permit adaptive water resources management under climate change. This paper presents a flexible methodology for conducting climate change risk assessments involving reservoir operations. Decision makers can apply this methodology to their systems by selecting future periods and risk metrics relevant to their planning questions and by collectively evaluating system impacts relative to an ensemble of climate projection scenarios (weighted or not). This paper shows multiple applications of this methodology in a case study involving California's Central Valley Project and State Water Project systems. Multiple applications were conducted to show how choices made in conducting the risk assessment, choices known as analytical design decisions, can affect assessed risk. Specifically, risk was reanalyzed for every choice combination of two design decisions: (1) whether to assume climate change will influence flood-control constraints on water supply operations (and how), and (2) whether to weight climate change scenarios (and how). Results show that assessed risk would motivate different planning pathways depending on decision-maker attitudes toward risk (e.g., risk neutral versus risk averse). Results also show that assessed risk at a given risk attitude is sensitive to the analytical design choices listed above, with the choice of whether to adjust flood-control rules under climate change having considerably more influence than the choice on whether to weight climate scenarios.

  11. Climate change adaptation and social sciences

    2013-01-01

    Climate change subjects societies to a large range of uncertainties concerning the future and their development orientation. It came up as a scientific global problem, extended to political concerns first at a global and then national scales. Though it has long been the object of economic approaches which have notably contributed to its recognition, particularly the Stern Report, social sciences have hardly been mobilized as part of policies to counteract it. Social sciences strongly question the notion of climate change being built as a global scale transcendent phenomenon, analyzed by several authors. With the rise of adaptation policies, the question becomes even more important. Adaptation first comes up as a spontaneous behaviour, independent of policy, in close relationship to social dimensions as a basic way through which climate change is grasped collectively. Thus adaptation policies' social aspects need to be carefully worked in relation with more general goals for adaptation policies to be implemented efficiently, on the basis of wide interactions between local and global scales.

    1990-01-01

    The impact of various international conferences concerning global climate change on international opinions and attitudes is discussed. A number of conferences over the past two decades have drawn attention to the large socio-economic consequences of climate change. There has been increasing attention given to the likely affect of anthropogenically derived greenhouse gases on the global climate. Some early uncertainty over the likely long term changes in global temperature have been replaced by a scientific consensus that global temperatures are increasing and will continue to do so into the next century. Public awareness of the possibility of climate change and severe socio-economic consequences has been increasing and was given a major impetus by the Toronto Conference on the Changing Atmosphere. An estimate of the possible time to solution of the climate change issue is given as 1988-2005, a span of 17 years. The Intergovernmental Panel on Climate Change has focused work into three working groups examining science, impacts and response strategies. 28 refs., 3 figs., 6 tabs

    Leadeship is an essential ingredient in reaching international agreements and overcoming the collective action problems associated with responding to climate change. In this study, we aim at answering two questions that are crucial for understanding the legitimacy of leadership in international climate change negotiations. Based on the responses of the three consecutive surveys distributed at COPs 14-16, we seek first to chart which actors are actually recognized as leaders by climate change negotiation participants. Second, we aim to explain what motivates COP participants to support different actors as leaders. Both these questions are indeed crucial for understanding the role, importance, and legitimacy of leadership in the international climate change regime. Our results show that the leadership landscape in this issue area is fragmented, with no one clear-cut leader, and strongly suggest that it is imperative for any actor seeking recognition as climate change leader to be perceived as being devoted to promoting the common good.

    1991-01-01

    The various agents of global change that will affect the state of natural resources 50-100 years from now are discussed. These include economic and population growth, technological progress, and climatic change. The importance of climatic change lies in its effects on natural resources and on human activities that depend on those resources. Other factors affecting those resources include the demand on those resources from an increasing population and from a growing economy, and a more efficient use of those resources that comes from technological changes and from the consequences of economic growth itself. It is shown that there is a considerable ability to adapt to climatic change, since humans already have an intrinsic ability to adapt to the wide variations in climates that already exist and since technological developments can make it easier to cope with climatic variability. It appears that agents other than climatic change are more significant to the future state of natural resources than climatic change. Criteria for selecting options for addressing climatic change are outlined. Technological change and economic growth are seen to be key response options, since the vulnerability to climatic change depends on economic resources and technological progress. Specific options to stimulate sustainable economic growth and technological progress are listed. 16 refs., 1 fig., 2 tabs

    2000-01-01

    Climate for Change: Non-State Actors and the Global Politics of the Greenhouse provides a challenging explanation of the forces that have shaped the international global warming debate. Unlike existing books on the politics of climate change, this book concentrates on how non-stage actors, such as scientific, environmental and industry groups, as opposed to governmental organisations, affect political outcomes in global fora on climate change. It also provides insights in to the role of the media in influencing the agenda. The book draws on a range of analytical approaches to assess and explain the influence of these non-governmental organisations in the course of global climate change politics. The book will be of interest to all researchers and policy-makers associated with climate change, and will be used on university courses in international relations, politics and environmental studies.

  17. Climate change

    2006-01-01

    This paper presented indicators of climate change for British Columbia (BC) with an emphasis on the coastal region. An overview of global effects of climate change was presented, as well as details of BC's current climate change action plan. Indicators examined in the paper for the BC coastal region included long-term trends in air temperature; long-term trends in precipitation; coastal ocean temperatures; sea levels on the BC coast; and the sensitivity of the BC coast to sea level rise and erosion. Data suggested that average air temperatures have become higher in many areas, and that Springtime temperatures have become warmer over the whole province. Winters have become drier in many areas of the province. Sea surface temperature has risen over the entire coast, with the North Coast and central Strait of Georgia showing the largest increases. Deep-water temperatures have also increased in 5 inlets on the South Coast. Results suggested that the direction and spatial pattern of the climate changes reported for British Columbia are consistent with broader trends in North America and the type of changes predicted by climate models for the region. Climate change will likely result in reduced snow-pack in southern BC. An earlier spring freshet on many snow-dominated river systems is anticipated as well as glacial retreat and disappearance. Warmer temperatures in some lakes and rivers are expected, as well as the increased frequency and severity of natural disturbances such as the pine mountain beetle. Large-scale shifts in ecosystems and the loss of certain ecosystems may also occur. BC's current climate plan includes cost effective actions that address GHG emissions and support efficient infrastructure and opportunities for innovation. Management programs for forest and agricultural lands have been initiated, as well as programs to reduce emissions from government operations. Research is also being conducted to understand the impacts of climate change on water

    A climate network of six climate indices of the North Pacific air—sea system is constructed during the period of 1948–2009. In order to find out the inherent relationship between the intrinsic mechanism of climate index network and the important climate shift, the synchronization behaviour and the coupling behaviour of these indices are investigated. Results indicate that climate network synchronization happened around the beginning of the 1960s, in the middle of the 1970s and at the beginnings of the 1990s and the 2000s separately. These synchronization states were always followed by the decrease of the coupling coefficient. Each synchronization of the network was well associated with the abrupt phase or trend changes of annually accumulated abnormal values of North Pacific sea-surface temperature and 500-hPa height, among which the one that happened in the middle of the 1970s is the most noticeable climate shift. We can also obtain this mysterious shift from the first mode of the empirical orthogonal function of six indices. That is to say, abrupt climate shift in North Pacific air—sea system is not only shown by the phase or trend changes of climate indices, but also might be indicated by the synchronizing and the coupling of climate indices. Furthermore, at the turning point of 1975, there are also abrupt correlation changes in the yearly mode of spatial degree distribution of the sea surface temperature and 500-hPa height in the region of the North Pacific, which further proves the probability of climate index synchronization and coupling shift in air—sea systems.

    held in the school under study. A critical description of the nature and content of communicated messages, activities and projects follows. Individual and collective initiatives which foster an interdisciplinary approach to climate change education are identified, as are the various obstacles to this approach, including organizational obstacles and the longstanding traditions of the French educational system which tend to hinder pedagogical innovation. Lastly, the reception of these projects and activities by school children in the second year of secondary school is analyzed. The results of this analysis are somewhat, but not always, encouraging. School children interviewed do not clearly understand the scientific phenomena surrounding climate change, and have difficulty considering this issue within its wider socio-political context. School children's interest in climate change and environmental science is largely dependent upon a perceived link with their own centers of interest or hobbies. School children express nonetheless the need for more and better adult mediation on the question of climate change, even though they see environmentally conscious behavior as contrary to the modern lifestyle of comfort that society offers them. Certain school projects and activities which had a particular impact on school children are discussed, in order to suggest criteria for evaluating the effectiveness (or non-effectiveness) of climate change projects in school. This study can be considered to be a tool for reflection and for the evaluation of the potential impact of climate change programs and messages produced for youngsters in school today

    2012-06-01

    Climate change is an increasingly salient issue for societies and policy-makers worldwide. It now raises fundamental interdisciplinary issues of risk and uncertainty analysis and communication. The growing scientific consensus over the anthropogenic causes of climate change appears to sit at odds with the increasing use of risk discourses in policy: for example, to aid in climate adaptation decision making. All of this points to a need for a fundamental revision of our conceptualization of what it is to do climate risk communication. This Special Collection comprises seven papers stimulated by a workshop on "Climate Risk Perceptions and Communication" held at Cumberland Lodge Windsor in 2010. Topics addressed include climate uncertainties, images and the media, communication and public engagement, uncertainty transfer in climate communication, the role of emotions, localization of hazard impacts, and longitudinal analyses of climate perceptions. Climate change risk perceptions and communication work is critical for future climate policy and decisions. © 2012 Society for Risk Analysis.

  4. Analysis of Nigerian insurers’ perceptions of climate change

    Full Text Available In recent times, global agricultural productivity has been increasingly affected by climate change. It is believed that societal adoption of insurance as an adaptive response to climate change can have significant implications for insurers. The study investigates empirically insurers’ perceptions of climate change and the challenges they face in Nigeria. It examines the proposition that insurance firms in Nigeria are not mindful of the impact of climate change. The study applied the use of descriptive statistics, Kendall’s coefficient of concordance and principal component analysis on collected primary data. It was found that insurers in Nigeria were highly aware of climate change and its impact but did not believe it affects their operational costs and payments of claims. Although there is great scope for insurers to increase their client base in the Nigerian market, insurers face challenges of insurance rate-cutting, low patronage and environmental factors. The study concludes that there is a need for insurance regulators to enforce a level playing field for all firms. It also advocates for public support of private insurers to enhance insurance coverage for agriculture, the largest employer of labour in the country.

  5. Climate change and precipitation: Detecting changes Climate change and precipitation: Detecting changes

    International Nuclear Information System (INIS)

    Van Boxel, John H

    2001-01-01

    Precipitation is one of the most, if not the most important climate parameter In most studies on climate change the emphasis is on temperature and sea level rise. Often too little attention is given to precipitation. For a large part this is due to the large spatial en temporal variability of precipitation, which makes the detection of changes difficult. This paper describes methods to detect changes in precipitation. In order to arrive at statistically significant changes one must use long time series and spatial averages containing the information from several stations. In the Netherlands the average yearly precipitation increased by 11% during the 20th century .In the temperate latitudes on the Northern Hemisphere (40-60QN) the average increase was about 7% over the 20th century and the globally averaged precipitation increased by about 3%. During the 20th century 38% of the land surface of the earth became wetter, 42% experienced little change (less than 5% change) and 20% became dryer. More important than the average precipitation is the occurrence of extremes. In the Netherlands there is a tendency to more extreme precipitations, whereas the occurrence of relatively dry months has not changed. Also in many other countries increases in heavy precipitation events are observed. All climate models predict a further increase of mean global precipitation if the carbon dioxide concentration doubles. Nevertheless some areas get dryer, others have little change and consequently there are also areas where the increase is much more than the global average. On a regional scale however there are large differences between the models. Climate models do not yet provide adequate information on changes in extreme precipitations

  7. Climate Change, Politics and Religion: Australian Churchgoers’ Beliefs about Climate Change

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available A growing literature has sought to understand the relationships between religion, politics and views about climate change and climate change policy in the United States. However, little comparative research has been conducted in other countries. This study draws on data from the 2011 Australian National Church Life Survey to examine the beliefs of Australian churchgoers from some 20 denominations about climate change—whether or not it is real and whether it is caused by humans—and political factors that explain variation in these beliefs. Pentecostals, Baptist and Churches of Christ churchgoers, and people from the smallest Protestant denominations were less likely than other churchgoers to believe in anthropogenic climate change, and voting and hierarchical and individualistic views about society predicted beliefs. There was some evidence that these views function differently in relation to climate change beliefs depending on churchgoers’ degree of opposition to gay rights. These findings are of interest not only for the sake of international comparisons, but also in a context where Australia plays a role in international climate change politics that is disproportionate to its small population.

    2012-01-01

    A climate envelope approach was used to model the response of switchgrass, a model bioenergy species in the United States, to future climate change. The model was built using general additive models (GAMs), and switchgrass yields collected at 45 field trial locations as the response variable. The model incorporated variables previously shown to be the main determinants of switchgrass yield, and utilized current and predicted 1 km climate data from WorldClim. The models were run with current WorldClim data and compared with results of predicted yield obtained using two climate change scenarios across three global change models for three time steps. Results did not predict an increase in maximum switchgrass yield but showed an overall shift in areas of high switchgrass productivity for both cytotypes. For upland cytotypes, the shift in high yields was concentrated in northern and north-eastern areas where there were increases in average growing season temperature, whereas for lowland cultivars the areas where yields were projected to increase were associated with increases in average early growing season precipitation. These results highlight the fact that the influences of climate change on switchgrass yield are spatially heterogeneous and vary depending on cytotype. Knowledge of spatial distribution of suitable areas for switchgrass production under climate change should be incorporated into planning of current and future biofuel production. Understanding how switchgrass yields will be affected by future changes in climate is important for achieving a sustainable biofuels economy. (letter)

    This paper outlines the different methods which may be used for the construction of regional climate change scenarios. The main focus of the paper is the construction of global climate change scenarios from climate change experiments carried out using General Circulation Models (GCMS) An introduction to some GCM climate change experiments highlights the difference between model types and experiments (e.g., equilibrium or transient). The latest generation of climate change experiments has been performed using fully coupled ocean-atmosphere GCMS. These allow transient simulations of climate change to be performed with respect to a given greenhouse gas forcing scenario. There are, however, a number of problems with these simulations which pose difficulties for the construction of climate change scenarios for use in climate change impacts assessment. The characteristics of the transient climate change experiments which pose difficulties for the construction of climate change scenarios are discussed. Three examples of these problems are: different climate change experiments use different greenhouse gas concentration scenarios; the 'cold-start' problem makes it difficult to link future projections of climate change to a given calendar year; a drift of the climate is noticeable in the control simulations. In order to construct climate change scenarios for impacts assessment a method has therefore to be employed which addresses these problems. At present the climate modeling and climate change impacts communities are somewhat polarized in their approach to spatial scales. Current GCMs model the climate at resolutions larger than 2.5 x 3.75 degree, while the majority of impacts assessment studies are undertaken at scales below 50km (or 0.5 degree). This paper concludes by addressing the problems in bringing together these two different modeling perspectives by presenting a number of regional climate change scenarios. 35 refs., 8 figs., 2 tabs

  11. Climate Change and Political Action: the Citizens' Climate Lobby

    Recognizing the reality of global warming and its origin in greenhouse gas emissions, what does one do about it? Individual action is commendable, but inadequate. Collective action is necessary--Citizens' Climate Lobby proposes a "fee-and-dividend" approach in which a fee is imposed on carbon-based fuel at its sources of production. The fee increases annually in a predictable manner. The funds collected are paid out to consumers as monthly dividends. The approach is market-based, in that the cost of the fee to producers is passed on to consumers in the cost of carbon-based fuels. Downstream energy providers and consumers then make their choices regarding investments and purchases. Citizens' Climate Lobby (CCL) builds national consensus by growing local Chapters, led and populated by volunteers. The Chapters are charged with public education and presenting the fee-and-dividend proposal to their respective Representatives and Senators. CCL builds trust by its non-partisan approach, meeting with all members of Congress regardless of party affiliation and stance on climate-related issues. CCL also builds trust by a non-confrontational approach, seeking to understand rather than to oppose. CCL works both locally, through its local Chapters, and nationally, with an annual conference in Washington DC during which all Congressional offices are visited. CCL recognizes that a long-term, sustained effort is necessary to address climate change.

    Estonia is among the countries who signed the Framework Convention on Climate Change (FCCC) at the UN Conference in Rio de Janeiro in June 1992. The FCCC calls on its parties to inventory national sources, to reduction in greenhouse gases and to development of projects responding to climate change. In 1994, an Estonian Country Study Project was initiated within the U.S. Country Studies Program. The Estonian Country Study Project is comprehensive, covering all sectors and directions of activity in Estonia that might impact climate change or be influenced by Global Climate Change. This book contains a collection of papers, covering the aims of the Estonian Country Study Project

    In this work, we present the design, implementation, and initial outcomes of the Climate Academy, a hybrid professional development program delivered through a combination of face-to-face and online interactions, intended to prepare formal and informal science teachers (grades 5-16) in teaching about climate change. The Climate Academy was designed around core elements of successful environmental professional development programs and aligned with practices advocated in benchmarked science standards. Data were collected from multiple sources including observations of professional development events, participants' reflections on their learning, and collection of instructional units designed during the Academy. Data were also collected from a focal case study teacher in a middle school setting. Case study data included classroom observations, teacher interviews, and student beliefs toward climate change. Results indicated that the Climate Academy fostered increased learning among participants of both climate science content and pedagogical strategies for teaching about climate change. Additionally, results indicated that participants applied their new learning in the design of climate change instructional units. Finally, results from the case study indicated positive impacts on student beliefs and greater awareness about climate change. Results have implications for the design of professional development programs on climate change, a topic included for the first time in national standards.

    Despite commanding essentially universal scientific consensus, climate change remains a divisive and poorly understood topic in the United States. Familiarity with this subject is not just for climate scientists. The impact of climate change on human morbidity and mortality may be considerable; thus, physicians also should be knowledgeable in this realm. Climate change science can seem opaque and inferential, creating fertile ground for political polemics and undoubtedly contributing to confusion among the general public. This puts physicians in a pivotal position to facilitate a practical understanding of climate change in the public sphere by discussing changes in disease patterns and their possible relationship to a changing climate. This article provides a background on climate change for dermatologists and highlights how climate change may impact the management of skin disease across the United States.

    Climate change has myriad implications for the health of humans, our ecosystems, and the ecological processes that sustain them. Projections of rising greenhouse gas emissions suggest increasing direct and indirect burden of infectious and noninfectious disease, effects on food and water security, and other societal disruptions. As the effects of climate change cannot be isolated from social and ecological determinants of disease that will mitigate or exacerbate forecasted health outcomes, multidisciplinary collaboration is critically needed. The aim of this article was to review the links between climate change and its upstream drivers (ie, processes leading to greenhouse gas emissions) and health outcomes, and identify existing opportunities to leverage more integrated global health and climate actions to prevent, prepare for, and respond to anthropogenic pressures. We conducted a literature review of current and projected health outcomes associated with climate change, drawing on findings and our collective expertise to review opportunities for adaptation and mitigation across disciplines. Health outcomes related to climate change affect a wide range of stakeholders, providing ready collaborative opportunities for interventions, which can be differentiated by addressing the upstream drivers leading to climate change or the downstream effects of climate change itself. Although health professionals are challenged with risks from climate change and its drivers, the adverse health outcomes cannot be resolved by the public health community alone. A phase change in global health is needed to move from a passive responder in partnership with other societal sectors to drive innovative alternatives. It is essential for global health to step outside of its traditional boundaries to engage with other stakeholders to develop policy and practical solutions to mitigate disease burden of climate change and its drivers; this will also yield compound benefits that help address

    The environmental and health consequences of climate change, which disproportionately affect low-income countries and poor people in high-income countries, profoundly affect human rights and social justice. Environmental consequences include increased temperature, excess precipitation in some areas and droughts in others, extreme weather events, and increased sea level. These consequences adversely affect agricultural production, access to safe water, and worker productivity, and, by inundating land or making land uninhabitable and uncultivatable, will force many people to become environmental refugees. Adverse health effects caused by climate change include heat-related disorders, vector-borne diseases, foodborne and waterborne diseases, respiratory and allergic disorders, malnutrition, collective violence, and mental health problems. These environmental and health consequences threaten civil and political rights and economic, social, and cultural rights, including rights to life, access to safe food and water, health, security, shelter, and culture. On a national or local level, those people who are most vulnerable to the adverse environmental and health consequences of climate change include poor people, members of minority groups, women, children, older people, people with chronic diseases and disabilities, those residing in areas with a high prevalence of climate-related diseases, and workers exposed to extreme heat or increased weather variability. On a global level, there is much inequity, with low-income countries, which produce the least greenhouse gases (GHGs), being more adversely affected by climate change than high-income countries, which produce substantially higher amounts of GHGs yet are less immediately affected. In addition, low-income countries have far less capability to adapt to climate change than high-income countries. Adaptation and mitigation measures to address climate change needed to protect human society must also be planned to protect

    2005-01-01

    To chart a way forward, an International Climate Change Taskforce, composed of leading scientists, public officials, and representatives of business and non-governmental organisations, was established at the invitation of three leading public policy institutes - the Institute for Public Policy Research, the Center for American Progress and The Australia Institute. The Taskforce's aim has been to develop proposals to consolidate and build on the gains achieved under the UNFCCC and the Kyoto Protocol to ensure that climate change is addressed effectively over the long term. In doing so, the Taskforce has met twice, in Windsor, United Kingdom and Sydney, Australia, where they reviewed and debated detailed research papers prepared by the Taskforce Secretariat, provided by the three founding organisations. The Taskforce's recommendations are to all governments and policy-makers worldwide. However, particular emphasis is placed on providing independent advice to the governments of the Group of Eight (G8) and the European Union (EU) in the context of the UK's presidencies of both organisations in 2005, during which Prime Minister Tony Blair has pledged to make addressing climate change a priority. The recommendations are also made in the context of the start of international negotiations in 2005 on future collective action on climate change, and the need to engage the governments of those industrialised countries that have not ratified the Kyoto Protocol

  20. Quality Climate Change Professional Development Translates into Quality Climate Change Education (Invited)

    2013-12-01

    Perhaps one of the reasons we have so many climate change deniers in the United States is that to them climate change is not occurring. This is a valid claim about climate change deniers considering that the effects of climate change in the mid-latitudes are quite subtle as compared to those found in low-latitude and high-latitude regions. A mid-latitude classroom teacher is saddled with the challenge of enlightening students about our changing climate and empowering students to assist in making necessary lifestyle changes, all the while the students don't understand the urgency in doing so. Quality climate change data and resources from the Polar Regions and low latitudes, as well as connections to researchers from these regions help to bridge the understanding of our changing climate from the extreme latitudes to the mid-latitudes. Connecting science teachers with data, resources, and researchers is one way of ensuring our mid-latitude students understand the urgency in taking appropriate actions to adapt, mitigate, and show resilience. This presentation will highlight a few of the many impacts of an authentic research experience for teachers that not only provides teachers with data, resources, and researchers, but changes the way a science teacher teaches where the methods they use mirror the methods used by scientists. National projects like PolarTREC connect educators with the science of climate change as well as the reality of impacts of climate change. For example, research expeditions in the Arctic and in Antarctica connect teachers with the content and practices of climate change science preparing them to replicate their experiences with their students. A PolarTREC experience does not end with the close of the expedition. Teachers continue their connections with the program through their educator network, the integration of PolarTREC resources into their curriculums, and communications with their principal investigators either virtually or with school

    The Report aims to improve understanding about the linkages between trade and climate change. It shows that trade intersects with climate change in a multitude of ways. For example, governments may introduce a variety of policies, such as regulatory measures and economic incentives, to address climate change. This complex web of measures may have an impact on international trade and the multilateral trading system. The Report begins with a summary of the current state of scientific knowledge on climate change and on the options available for responding to the challenge of climate change. The scientific review is followed by a part on the economic aspects of the link between trade and climate change, and these two parts set the context for the subsequent parts of the Report, which looks at the policies introduced at both the international and national level to address climate change. The part on international policy responses to climate change describes multilateral efforts to reduce greenhouse gas emissions and to adapt to the effects of climate change, and also discusses the role of the current trade and environment negotiations in promoting trade in technologies that aim to mitigate climate change. The final part of the Report gives an overview of a range of national policies and measures that have been used in a number of countries to reduce greenhouse gas emissions and to increase energy efficiency. It presents key features in the design and implementation of these policies, in order to draw a clearer picture of their overall effect and potential impact on environmental protection, sustainable development and trade. It also gives, where appropriate, an overview of the WTO rules that may be relevant to such measures. (author)

    The Intergovernmental Panel on Climate Change (IPCC) has finalized its Third Assessment Report. Among its conclusions is that we must expect continued changes in our climate, despite our efforts to reduce greenhouse gas emissions. Planning for and adapting to climate change are therefore necessary. As a starting point, CICERO has written this short note on expected impacts in Norway. The main conclusions are that (1) Adaptation to climate change is necessary (2) Substantial impacts are expected for several important sectors in Norway (3) The local and central authorities should now consider and start planning for adaptation measures. (4) There is still a need for more knowledge about potential impacts of climate change in Norway. (author)

    Adoption of science content standards that include anthropogenic climate change has prompted widespread instruction in climate change for the first time. However, the controversial nature of the topic can be daunting and many teachers share misconceptions that lead to weak treatment of climate change in classrooms. Nevertheless, numerous teachers have embraced the topic and are providing illustrations of deliberate climate change education. In this study we investigated teacher motivation using focus groups with middle school teachers who currently teach climate change. Qualitative analysis of the collective teacher voices yielded underlying motivations. Our findings suggest that these teachers' interest in environmentalism naturally translates to climate change advocacy and motivates teaching the topic. Their knowledge and expertise gives them confidence to teach it. These teachers see themselves as scientists, therefore their views align with the scientific consensus. They practice authentic scientific research with their students, thus confirming valued characteristics of their scientist identity. Finally, our findings suggest that teaching climate change gives these teachers a sense of hope as they impact the future through their students. This study contrasts with skepticism over the state of climate change education and contributes to an understanding of how climate change education is motivated in teachers.

    The purpose of the National Forum on Climate Change was to raise public awareness of the climate change issue and to bring citizens` viewpoint to the debate. The Forum was a unique conference in that the principal attendees, while lay persons as far as climate change is concerned, were members of the Order of Canada. The Order of Canada is an honour bestowed upon upon a relatively small number of Canadian citizens from all walks of life who have made significant contributions to the betterment of their professions or communities or distinguished themselves nationally or internationally. It was the first time that recipients of this high honour were called upon collectively to address an issue of national policy. This declaration was issued at the conclusion of the round table discussions. It expresses their conclusions about climate change, what it is, what are its potential impacts, the scientific uncertainties surrounding the issue, and the actions that can and must be taken by governments and individual citizens to deal with the problem.

    2014-01-01

    The focus of the great majority of climate change impact studies is on changes in mean climate. In terms of climate model output, these changes are more robust than changes in climate variability. By concentrating on changes in climate means, the full impacts of climate change on biological and human systems are probably being seriously underestimated. Here, we briefly review the possible impacts of changes in climate variability and the frequency of extreme events on biological and food systems, with a focus on the developing world. We present new analysis that tentatively links increases in climate variability with increasing food insecurity in the future. We consider the ways in which people deal with climate variability and extremes and how they may adapt in the future. Key knowledge and data gaps are highlighted. These include the timing and interactions of different climatic stresses on plant growth and development, particularly at higher temperatures, and the impacts on crops, livestock and farming systems of changes in climate variability and extreme events on pest-weed-disease complexes. We highlight the need to reframe research questions in such a way that they can provide decision makers throughout the food system with actionable answers, and the need for investment in climate and environmental monitoring. Improved understanding of the full range of impacts of climate change on biological and food systems is a critical step in being able to address effectively the effects of climate variability and extreme events on human vulnerability and food security, particularly in agriculturally based developing countries facing the challenge of having to feed rapidly growing populations in the coming decades.

    International Nuclear Information System (INIS)

    World Energy Council

    2007-01-01

    The world needs urgently to develop a coherent and practical approach to reducing greenhouse gas (ghg) emissions. Energy professionals from across the world have been examining climate change policies to see what works in promoting sustainable development. The Intergovernmental Panel on Climate Change has recently confirmed that the evidence for global warming is unequivocal and the Stern Report has argued that early action to combat climate change makes economic sense. However, existing efforts are clearly insufficient - most countries with targets under Kyoto Protocol are not on track to meeting them and many countries do not have Kyoto targets. As a result, ghg emissions are still rising and are forecast to go on doing so for decades to come. The problem is not a lack of policies to deal with climate change - some thousands of policies have been introduced, both by countries within the Kyoto system and those outside, and the effort is under way to develop a successor to the Kyoto Protocol. Yet so far those policies are not proving adequate to the scale of the problem. There is a pressing need to understand why they are failing and to implement measures that are more effective in reducing emissions, particularly from the energy sector, which accounts for around two thirds of total ghg emissions. The WEC has therefore undertaken a Study of Energy and Climate Change, drawing on the collective experience and resources of energy professionals worldwide. It has looked in detail at the impact of existing climate change measures and how effective they have been in promoting sustainable development, using the criteria of the three A's - accessibility (to affordable energy); acceptability (of the energy sources used, particularly in environmental terms); and availability (how secure and reliable are those sources?). It is important to remember that sustainable development is not only about the environment - policies which fail to contribute to economic and social

    mobilize and redistribute volatile reservoirs both on and below the surface. And for Mars, these variations are large. In the past 20 My, for example, the obliquity is believed to have varied from a low of 15° to a high of 45° with a regular oscillation time scale of ~10^5 years. These variations are typically less than two degrees on the Earth. Mars, therefore, offers a natural laboratory for the study of orbitally induced climate change on a terrestrial planet. Finally, general circulation models (GCMs) for Mars have reached a level of sophistication that justifies their application to the study of spin axis/orbitally forced climate change. With recent advances in computer technology the models can run at reasonable spatial resolution for many Mars years with physics packages that include cloud microphysics, radiative transfer in scattering/absorbing atmospheres, surface heat budgets, boundary layer schemes, and a host of other processes. To be sure, the models will undergo continual improvement, but with carefully designed experiments they can now provide insights into mechanisms of climate change in the recent past. Thus, the geologic record is better preserved, the forcing function is large, and GCMs have become useful tools. While research efforts in each of these areas have progressed considerably over the past several decades, they have proceeded mostly on independent paths occasionally leading to conflicting ideas. To remedy this situation and accelerate progress in the area, the NASA/Ames Research Center's Mars General Circulation Modeling Group hosted a 3-day workshop on May 15-17, 2012 that brought together the geological and atmospheric science communities to collectively discuss the evidence for recent climate change on Mars, the nature of the change required, and how that change could be brought about. Over 50 researchers, students, and post-docs from the US, Canada, Europe, and Japan attended the meeting. The program and abstracts from the workshop are

    Climate change is a global problem. Because of unlimited use of fossil energy and resulting greenhouse gas emissions the global temperature is rising causing floods, draughts and storms in all parts of the world with increasing frequency and strength. Dangerous climate change will occur with high probability after the global temperature has passed a certain threshold [1]. To avoid dangerous climate change global greenhouse gas emissions must be reduced to a level of 50% or less of the year-2000 emissions by 2050 [2-4]. All people on earth take part in this global target public goods game, "a game that we cannot afford to loose" [5]. Simulating this scenario in a nutshell a collective risk social dilemma game has shown that a small group of subjects can achieve a collective goal by sequential individual contributions but only when the risk of loosing their not invested money is high, e.g. 90% [6]. Cooperation in public goods games usually decreases with increasing group size [7]. Thus, does this mean that the global game will be lost?

    Recent research has highlighted risks associated with the use of climate engineering as a method of stabilizing global temperatures, including the possibility of rapid climate warming in the case of abrupt removal of engineered radiative forcing. In this study, we have used a simple climate model to estimate the likely range of temperature changes associated with implementation and removal of climate engineering. In the absence of climate engineering, maximum annual rates of warming ranged from 0.015 to 0.07 deg. C/year, depending on the model's climate sensitivity. Climate engineering resulted in much higher rates of warming, with the temperature change in the year following the removal of climate engineering ranging from 0.13 to 0.76 deg. C. High rates of temperature change were sustained for two decades following the removal of climate engineering; rates of change of 0.5 (0.3,0.1) deg. C/decade were exceeded over a 20 year period with 15% (75%, 100%) likelihood. Many ecosystems could be negatively affected by these rates of temperature change; our results suggest that climate engineering in the absence of deep emissions cuts could arguably constitute increased risk of dangerous anthropogenic interference in the climate system under the criteria laid out in the United Nations Framework Convention on Climate Change.

    Climate change deeply impacts human wellbeing. Significant amounts of resources have been invested in building super-computers that are capable of running advanced climate models, which help scientists understand climate change mechanisms, and predict its trend. Although climate change influences all human beings, the general public is largely excluded from the research. On the other hand, scientists are eagerly seeking communication mediums for effectively enlightening the public on climate change and its consequences. The Climate@Home project is devoted to connect the two ends with an innovative solution: crowdsourcing climate computing to the general public by harvesting volunteered computing resources from the participants. A distributed web-based computing platform will be built to support climate computing, and the general public can 'plug-in' their personal computers to participate in the research. People contribute the spare computing power of their computers to run a computer model, which is used by scientists to predict climate change. Traditionally, only super-computers could handle such a large computing processing load. By orchestrating massive amounts of personal computers to perform atomized data processing tasks, investments on new super-computers, energy consumed by super-computers, and carbon release from super-computers are reduced. Meanwhile, the platform forms a social network of climate researchers and the general public, which may be leveraged to raise climate awareness among the participants. A portal is to be built as the gateway to the climate@home project. Three types of roles and the corresponding functionalities are designed and supported. The end users include the citizen participants, climate scientists, and project managers. Citizen participants connect their computing resources to the platform by downloading and installing a computing engine on their personal computers. Computer climate models are defined at the server side. Climate

    This article contributes to the understanding of how to proceed with the development of index-insurance in order to reach extended population coverage with the insurance. The approach is applied to an example from a region in Tanzania. One of the main coping strategies that resource-poor households...... networks become insufficient since the majority of risk-sharers will be affected by the shock at the same time. This paper proposes a collective approach to index-insurance in which the members of an informal network will be insured as one insurance taker. The paper raises a conceptual argument...... that targeting households through existing informal networks will remove a number of prevailing barriers to the takeup of insurance and consequently the approach has the potential to increase households’ resilience to climate change impacts. The policy implications of the conclusions are significant since...

    Global warming has become in few years a prominent problem which requires the implementation of a world governance to be solved. However, the share of human activities in the global warming phenomenon and the actions susceptible to mitigate the greenhouse gases emission generate scientifical, political and legal conflicts at the same time. Assessing the taking into account of climate change by international institutions raises several questions. By what process a true fact can become established at the world scale? Are experts free or constrain by procedure rules? How to regulate the worldwide carbon trade? Is the governance requirement foreseen in international systems respected by decision making practices? How to explain experts' omnipresence in the observance mechanisms of climate change treaties? Is their influence determining, at the international and internal scale, in the elaboration of a climate law? These questions, analyzed by researchers in law and political science, are indissociable of method stakes with an inter-disciplinary horizon. This book, result of a collective work, is not limited to a description of standards and actors' practices in force. Its ambition is to apprehend law, science and politics in their interactions. Climate change is an appropriate topic to think about the links between the different scientific disciplines. The book concludes with a prospective about the contribution of laws analysis to expertise which involves the dogmatic, realistic and epistemologic aspects. (J.S.)

  8. Predicted Changes in Climatic Niche and Climate Refugia of Conservation Priority Salamander Species in the Northeastern United States

    Directory of Open Access Journals (Sweden)

    William B. Sutton

    2014-12-01

    Full Text Available Global climate change represents one of the most extensive and pervasive threats to wildlife populations. Amphibians, specifically salamanders, are particularly susceptible to the effects of changing climates due to their restrictive physiological requirements and low vagility; however, little is known about which landscapes and species are vulnerable to climate change. Our study objectives included, (1 evaluating species-specific predictions (based on 2050 climate projections and vulnerabilities to climate change and (2 using collective species responses to identify areas of climate refugia for conservation priority salamanders in the northeastern United States. All evaluated salamander species were projected to lose a portion of their climatic niche. Averaged projected losses ranged from 3%–100% for individual species, with the Cow Knob Salamander (Plethodon punctatus, Cheat Mountain Salamander (Plethodon nettingi, Shenandoah Mountain Salamander (Plethodon virginia, Mabee’s Salamander (Ambystoma mabeei, and Streamside Salamander (Ambystoma barbouri predicted to lose at least 97% of their landscape-scale climatic niche. The Western Allegheny Plateau was predicted to lose the greatest salamander climate refugia richness (i.e., number of species with a climatically-suitable niche in a landscape patch, whereas the Central Appalachians provided refugia for the greatest number of species during current and projected climate scenarios. Our results can be used to identify species and landscapes that are likely to be further affected by climate change and potentially resilient habitats that will provide consistent climatic conditions in the face of environmental change.

    The current consensus on climatic change in Canada is briefly summarized, noting the results of modelling of the effects of a doubling of atmospheric CO 2 , the nonuniformity of climate change across the country, the uncertainties in local responses to change, and the general agreement that 2-4 degrees of warming will occur for each doubling of CO 2 . Canadian government response includes programs aimed at reducing the uncertainties in the scientific understanding of climate change and in the socio-economic response to such change. Canadian climate change programs include participation in large-scale experiments on such topics as heat transport in the ocean, and sources and sinks of greenhouse gases; development of next-generation climate models; studying the social and economic effects of climate change in the Great Lakes Basin and Mackenzie River Basin; investigation of paleoclimates; and analysis of climate data for long-term trends

  15. The social construct of climate and climate change

    International Nuclear Information System (INIS)

    Stehr, N.

    1994-01-01

    Different time scales of climate change and their differential perception in society are discussed. A historical examination of natural climate changes during the past millennium suggests that short-term changes, especially crucial changes, trigger a significant response in and by society. Short-term changes correspond to the 'time horizon of everyday life', that is, to a time scale from days and weeks to a few years. The anticipated anthropogenic climate changes, however, are expected to occur on a longer time scale. They require a response by society not on the basis of primary experience but on the basis of scientifically constructed scenarios and ways in which such information is represented in the modern media for example. Socio-economic impact research relies on concepts that are based on the premise of perfectly informed actors for the development of optimal adaptation strategies. In contrast to such a conception, we develop the concept of a 'social construct of climate' as decisive for the public perception of scientific knowledge about climate and for public policy on climate change. The concept is illustrated using a number of examples. (orig.)

    Directional climate change (global warming) is causing rapid alterations in animals' environments. Because the nervous system is at the forefront of animals' interactions with the environment, the neurobiological implications of climate change are central to understanding how individuals, and ultimately populations, will respond to global warming. Evidence is accumulating for individual level, mechanistic effects of climate change on nervous system development and performance. Climate change can also alter sensory stimuli, changing the effectiveness of sensory and cognitive systems for achieving biological fitness. At the population level, natural selection forces stemming from directional climate change may drive rapid evolutionary change in nervous system structure and function.

    2017-12-01

    The purpose of the study was to understand the relationship between teachers' beliefs and understandings of climate change and their instructional practices to determine if and how they impact student outcomes. Limited research has been done in the area of teacher beliefs on climate change, their instruction, and resulting student outcomes. This study contributes to the greater understanding of teachers' beliefs and impact on climate change curriculum implementation. The study utilized a mixed methods approach to data collection and analysis. Data were collected in the form of classroom observations, surveys, and interviews from teachers and students participating in the study over a four-month period. Qualitative and quantitative findings were analyzed through thematic coding and descriptive analysis and compared in an effort to triangulate findings. The results of the study suggest teachers and students believe climate change is occurring and humans are largely to blame. Personal beliefs are important when teaching controversial topics, such as climate change, but participants maintained neutrality within their instruction of the topic, as not to appear biased or influence students' decisions about climate change, and avoid political controversy in the classroom. Overall, the study found teachers' level of understandings and beliefs about climate change had little impact on their instruction and resulting student outcomes. Based on the findings, simply adding climate change to the existing science curriculum is not sufficient for teachers or students. Teachers need to be better prepared about effective pedagogical practices of the content in order to effectively teach a climate-centered curriculum. The barriers that exist for the inclusion of teachers' personal beliefs need to be removed in order for teachers to assert their own personal beliefs about climate change within their classroom instruction. Administrators and stakeholders need to support science

    The Helsinki Metropolitan Area Climate Change Adaptation Strategy has been prepared in close cooperation with the four cities of the metropolitan area (Helsinki, Espoo, Vantaa and Kauniainen), the Helsinki Region Environmental Services Authority HSY and other municipal, regional and state level organisations. In the strategy, strategic starting points and policies with which the metropolitan area prepares for the consequences of climate change, are compiled. The Helsinki Metropolitan Area adaptation strategy concentrates on the adaptation of the built and urban environment to the changing climate. The vision of the strategy is climate proof city - the future is built now. The strategy aims to (1) assess the impacts of climate change in the area, (2) prepare for the impacts of climate change and to extreme weather events and (3) to reduce the vulnerabilities of the area to climate variability and change. The target is to secure the well-being of the citizens and the functioning of the cities also in the changing climate conditions. The preparation of the adaptation strategy started in 2009 by producing the background studies. They include the regional climate and sea level scenarios, modelling of river floods in climate change conditions and a survey of climate change impacts in the region. Also, existing programmes, legislation, research and studies concerning adaptation were collected. The background studies are published in a report titled 'The Helsinki metropolitan area climate is changing - Adaptation strategy background studies' (in Finnish) (HSY 2010). HSY coordinated the strategy preparation. The work was carried out is close cooperation with the experts of the metropolitan area cities, regional emergency services, Ministry of the Environment, Helsinki Region Transport Authority and other regional organisations. The strategy work has had a steering group that consists of representatives of the cities and other central cooperation partners. The

    We would like to talk about a multidisciplinary education and outreach program we co-direct at Colorado State University, with support from an NSF-funded STC, CMMAP, the Center for Multiscale Modeling of Atmospheric Processes. We are working to raise public literacy about climate change by providing information that is high quality, up to date, thoroughly multidisciplinary, and easy for non-specialists to understand. Our primary audiences are college-level students, their teachers, and the general public. Our motto is Climate Change is Everybody's Business. To encourage and help our faculty infuse climate-change content into their courses, we have organized some 115 talks given by as many different speakers-speakers drawn from 28 academic departments, all 8 colleges at CSU, and numerous other entities from campus, the community, and farther afield. We began with a faculty-teaching-faculty series and then broadened our attentions to the whole campus and surrounding community. Some talks have been for narrowly focused audiences such as extension agents who work on energy, but most are for more eclectic groups of students, staff, faculty, and citizens. We count heads at most events, and our current total is roughly 6,000. We have created a website (http://changingclimates.colostate.edu) that includes videotapes of many of these talks, short videos we have created, and annotated sources that we judge to be accurate, interesting, clearly written, and aimed at non-specialists, including books, articles and essays, websites, and a few items specifically for college teachers (such as syllabi). Pages of the website focus on such topics as how the climate works / how it changes; what's happening / what might happen; natural ecosystems; agriculture; impacts on people; responses from ethics, art, literature; communication; daily life; policy; energy; and-pulling all the pieces together-the big picture.

  5. Changes in the Perceived Risk of Climate Change: Evidence from Sudden Climatic Events

    Science.gov (United States)

    Anttila-Hughes, J. K.

    2009-12-01

    In the course of the past two decades the threat of anthropogenic climate change has moved from a scientific concern of relative obscurity to become one of the largest environmental and public goods problems in history. During this period public understanding of the risk of climate change has shifted from negligible to quite large. In this paper I propose a means of quantifying this change by examining how sudden events supporting the theory of anthropogenic climate change have affected carbon intensive companies' stock prices. Using CAPM event study methodology for companies in several carbon-intensive industries, I find strong evidence that markets have been reacting to changes in the scientific evidence for climate change for some time. Specifically, the change in magnitude of response over time seems to indicate that investors believed climate change was a potentially serious risk to corporate profits as early as the mid 1990s. Moreover, market reaction dependence on event type indicates that investors are differentiating between different advances in the scientific knowledge. Announcements by NASA GISS that the previous year was a “record hot year” for the globe are associated with negative excess returns, while news of ice shelf collapses are associated with strong positive excess returns. These results imply that investors are aware of how different aspects of climate change will affect carbon intensive companies, specifically in terms of the link between warming in general and polar ice cover. This implies that policy choices based on observable public opinion have lagged actual private concern over climate change's potential threat.

    2003-10-17

    Many papers have referred to a "Medieval Warm Period." But how well defined is climate in this period, and was it as warm as or warmer than it is today? In their Perspective, Bradley et al. review the evidence and conclude that although the High Medieval (1100 to 1200 A.D.) was warmer than subsequent centuries, it was not warmer than the late 20th century. Moreover, the warmest Medieval temperatures were not synchronous around the globe. Large changes in precipitation patterns are a particular characteristic of "High Medieval" time. The underlying mechanisms for such changes must be elucidated further to inform the ongoing debate on natural climate variability and anthropogenic climate change.

    2016-08-01

    Factors influencing climate change perceptions have vital roles in designing strategies to enrich climate change understanding. Despite this, factors that influence smallholder farmers' climate change perceptions have not yet been adequately studied. As many of the smallholder farmers live in regions where climate change is predicted to have the most negative impact, their climate change perception is of particular interest. In this study, based on data collected from Ethiopian smallholder farmers, we assessed farmers' perceptions and anticipations of past and future climate change. Furthermore, the factors influencing farmers' climate change perceptions and the relation between farmers' perceptions and available public climate information were assessed. Our findings revealed that a majority of respondents perceive warming temperatures and decreasing rainfall trends that correspond with the local meteorological record. Farmers' perceptions about the past climate did not always reflect their anticipations about the future. A substantial number of farmers' anticipations of future climate were less consistent with climate model projections. The recursive bivariate probit models employed to explore factors affecting different categories of climate change perceptions illustrate statistical significance for explanatory variables including location, gender, age, education, soil fertility status, climate change information, and access to credit services. The findings contribute to the literature by providing evidence not just on farmers' past climate perceptions but also on future climate anticipations. The identified factors help policy makers to provide targeted extension and advisory services to enrich climate change understanding and support appropriate farm-level climate change adaptations.

  14. Data Requirements for Developing Adaptations to Climate Variability and Change

    International Nuclear Information System (INIS)

    Basher, Reid E.

    1999-01-01

    An extensive foundation of high quality data and information on the climate and on the biological, environmental and social systems affected by climate is required in order to understand the climate impact processes involved, to develop new adaptation practices, and to subsequently implement these practices. Experience of the impacts of current and past variability of climate and sea level is a prime source of information. Many practices are in use to reduce climate impacts, for example in engineering design, agricultural risk management and climate prediction services, though their roles as adaptations to climate change are not widely appreciated. While there are good data sets on some factors and in some regions, in many cases the databases are inadequate and there are few data sets on adaptation-specific quantities such as vulnerability, resilience and adaptation effectiveness. Current international action under the United Nations Framework Convention on Climate Change (UNFCCC) pays little attention to adaptation and its information requirements. Furthermore there are trends toward reduced data gathering and to restrictions on access to data sets, especially arising from cost and commercialisation pressures. To effectively respond to the changes in climate that are now inevitable, governments will need to more clearly identify adaptation as a central feature of climate change policy and make a renewed shared commitment to collecting and freely exchanging the necessary data. 12 refs

    Agricultural production is sensitive to weather and thus directly affected by climate change. Plausible estimates of these climate change impacts require combined use of climate, crop, and economic models. Results from previous studies vary substantially due to differences in models, scenarios, and data. This paper is part of a collective effort to systematically integrate these three types of models. We focus on the economic component of the assessment, investigating how nine global economic models of agriculture represent endogenous responses to seven standardized climate change scenarios produced by two climate and five crop models. These responses include adjustments in yields, area, consumption, and international trade. We apply biophysical shocks derived from the Intergovernmental Panel on Climate Change's representative concentration pathway with end-of-century radiative forcing of 8.5 W/m(sup 2). The mean biophysical yield effect with no incremental CO2 fertilization is a 17% reduction globally by 2050 relative to a scenario with unchanging climate. Endogenous economic responses reduce yield loss to 11%, increase area of major crops by 11%, and reduce consumption by 3%. Agricultural production, cropland area, trade, and prices show the greatest degree of variability in response to climate change, and consumption the lowest. The sources of these differences include model structure and specification; in particular, model assumptions about ease of land use conversion, intensification, and trade. This study identifies where models disagree on the relative responses to climate shocks and highlights research activities needed to improve the representation of agricultural adaptation responses to climate change.

    2009-02-01

    This Climate Change Action Plan described the measures that are being taken by the Yukon Government to adapt to, understand, and reduce contributions to climate change. The action plan is the result of input received from more than 100 individuals and organizations and provides clear direction for a strategy that will minimize the negative impacts of climate change and provide economic, social and other environmental benefits through climate change mitigation. The Yukon government has already taken many actions that respond to climate change, such as: developing the Yukon Cold Climate Innovation Centre; supporting the Northern Climate Exchange for public education and outreach; funding community recycling depots and other groups that reduce waste generation, promote public awareness and divert solid waste; and working with provincial and territorial counterparts to enhance national building standards. The main objectives of the climate change actions are to enhance knowledge and understanding of climate change; adapt to climate change; reduce greenhouse gas emissions; and lead Yukon action in response to climate change. tabs., figs.

    Climate change further exacerbates the enormous existing burden of undernutrition. It affects food and nutrition security and undermines current efforts to reduce hunger and promote nutrition. Undernutrition in turn undermines climate resilience and the coping strategies of vulnerable populations. The objectives of this paper are to identify and undertake a cross-sectoral analysis of the impacts of climate change on nutrition security and the existing mechanisms, strategies, and policies to address them. A cross-sectoral analysis of the impacts of climate change on nutrition security and the mechanisms and policies to address them was guided by an analytical framework focused on the three 'underlying causes' of undernutrition: 1) household food access, 2) maternal and child care and feeding practices, 3) environmental health and health access. The analytical framework includes the interactions of the three underlying causes of undernutrition with climate change,vulnerability, adaptation and mitigation. Within broad efforts on climate change mitigation and adaptation and climate-resilient development, a combination of nutrition-sensitive adaptation and mitigation measures, climate-resilient and nutrition-sensitive agricultural development, social protection, improved maternal and child care and health, nutrition-sensitive risk reduction and management, community development measures, nutrition-smart investments, increased policy coherence, and institutional and cross-sectoral collaboration are proposed as a means to address the impacts of climate change to food and nutrition security. This paper proposes policy directions to address nutrition in the climate change agenda and recommendations for consideration by the UN Framework Convention on Climate Change (UNFCCC). Nutrition and health stakeholders need to be engaged in key climate change adaptation and mitigation initiatives, including science-based assessment by the Intergovernmental Panel on Climate Change (IPCC

    We describe briefly here the main mechanisms and time scales involved in natural and anthropogenic climate variability, based on quantitative paleo-climatic reconstructions from natural archives and climate model simulations: the large glacial-interglacial cycles of the last million years (the Quaternary), lasting typically a hundred thousand years, triggered by changes in the solar radiation received by the Earth due to its position around the Sun; the century-long climatic changes occurring during last glacial period and triggered by recurrent iceberg discharges of the large northern hemisphere ice caps, massive freshwater flux to the north Atlantic, and changes in the ocean heat transport. We show the strong coupling between past climatic changes and global biogeochemical cycles, namely here atmospheric greenhouse gases. We also discuss the decadal climatic fluctuations during the last thousand years, showing an unprecedented warming attributed to the anthropogenic greenhouse gas emissions. We show the range of atmospheric greenhouse concentrations forecasted for the end of the 21. century and the climate model predictions for global temperature changes during the 21. century. We also discuss the possible climatic changes at longer time scales involving the possibility of north Atlantic heat transport collapse (possibility of abrupt climate change), and the duration of the current interglacial period.

    A work is devoted to the application of an information-computational Web GIS "Climate" developed by joint team of the Institute of Monitoring of Climatic and Ecological Systems SB RAS and Tomsk State University to raise awareness about current and future climate change as a basis for further adaptation. Web-GIS "Climate» (http://climate.scert.ru/) based on modern concepts of Web 2.0 provides opportunities to study regional climate change and its consequences by providing access to climate and weather models, a large set of geophysical data and means of processing and visualization. Also, the system is used for the joint development of software applications by distributed research teams, research based on these applications and undergraduate and graduate students training. In addition, the system capabilities allow creating information resources to raise public awareness about climate change, its causes and consequences, which is a necessary step for the subsequent adaptation to these changes. Basic information course on climate change is placed in the public domain and is aimed at local population. Basic concepts and problems of modern climate change and its possible consequences are set out and illustrated in accessible language. Particular attention is paid to regional climate changes. In addition to the information part, the course also includes a selection of links to popular science network resources on current issues in Earth Sciences and a number of practical tasks to consolidate the material. These tasks are performed for a particular territory. Within the tasks users need to analyze the prepared within the "Climate" map layers and answer questions of direct interest to the public: "How did the minimum value of winter temperatures change in your area?", "What are the dynamics of maximum summer temperatures?", etc. Carrying out the analysis of the dynamics of climate change contributes to a better understanding of climate processes and further adaptation

    Full Text Available A majority of secondary science teachers are found to include the topic of climate change in their courses. However, teachers informally and sporadically discuss climate change and students rarely understand the underlying scientific concepts. The project team developed an innovative pedagogical approach, in which teachers and students learn climate change concepts by analyzing National Aeronautics and Space Administration (NASA global data collected through satellites and by imitating the NASA data collection process through NASA Airborne Earth Research Observation Kites And Tethered Systems (AEROKATS, a kite-borne remote sensing system. Besides AEROKATS, other major components of this system include a web-collection of NASA and remote sensing data and related educational resources, project-based learning for teacher professional development, teacher and student field trips, iOS devices, smart field data collector apps, portable weather stations, probeware, and a virtual teacher collaboratory supported with a GIS-enabled mapping portal. Three sets of research instruments, the NASA Long-Term Experience –Educator End of Event Survey, the Teacher End of Project Survey, and the pre-and-post-Investigating Climate Change and Remote Sensing (ICCARS project student exams, are adapted to study the pedagogical impacts of the NASA AEROKATS remote sensing system. These findings confirm that climate change education is more effective when both teachers and students actively participate in authentic scientific inquiry by collecting and analyzing remote sensing data, developing hypotheses, designing experiments, sharing findings, and discussing results.

    Climate change is altering life at multiple scales, from genes to ecosystems. Predicting the vulnerability of populations to climate change is crucial to mitigate negative impacts. We suggest that regional patterns of spatial and temporal climatic variation scaled to the traits of an organism can predict where and why populations are most vulnerable to climate change. Specifically, historical climatic variation affects the sensitivity and response capacity of populations to climate change by shaping traits and the genetic variation in those traits. Present and future climatic variation can affect both climate change exposure and population responses. We provide seven predictions for how climatic variation might affect the vulnerability of populations to climate change and suggest key directions for future research. Copyright © 2017 Elsevier Ltd.

    Marked climate change has been forecast for regions in high latitudes by global climate models presented by the Intergovernmental Panel on Climate Change. Observations and reports of significant alterations to the natural environment of Canada's north have been reported by Inuit and other indigenous peoples using their traditional ecological knowledge as a reference. Global climate change appears to be the cause for the changes noted. Many aspects of climate change need to be addressed, such as research, outreach, impacts, adaptations and international negotiations. Based on the strong partnership that had been developed between the Inuit and four federal agencies, three territorial governments and four indigenous people's organizations in support of the Northern Contaminants Program, Inuit are now seeking a partnership with the federal government to address the issues mentioned above concerning climate change. refs., 1 tab.

    Mozambique, like many African countries, is already highly susceptible to climate variability and extreme weather events. Climate change threatens to heighten this vulnerability. In order to evaluate potential impacts and adaptation options for Mozambique, we develop an integrated modeling...... framework that translates atmospheric changes from general circulation model projections into biophysical outcomes via detailed hydrologic, crop, hydropower and infrastructure models. These sector models simulate a historical baseline and four extreme climate change scenarios. Sector results are then passed...... down to a dynamic computable general equilibrium model, which is used to estimate economy-wide impacts on national welfare, as well as the total cost of damages caused by climate change. Potential damages without changes in policy are significant; our discounted estimates range from US2.3 to US2.3toUS7...

    Future climate change is predicted to diminish essential natural resource availability in many regions and perhaps globally. The resulting scarcity of water, food and livelihoods could lead to increasingly desperate populations that challenge governments, enhancing the risk of intra- and interstate conflict. Defence establishments and some political scientists view climate change as a potential threat to peace. While the medical literature increasingly recognises climate change as a fundamental health risk, the dimension of climate change-associated conflict has so far received little attention, despite its profound health implications. Many analysts link climate change with a heightened risk of conflict via causal pathways which involve diminishing or changing resource availability. Plausible consequences include: increased frequency of civil conflict in developing countries; terrorism, asymmetric warfare, state failure; and major regional conflicts. The medical understanding of these threats is inadequate, given the scale of health implications. The medical and public health communities have often been reluctant to interpret conflict as a health issue. However, at times, medical workers have proven powerful and effective peace advocates, most notably with regard to nuclear disarmament. The public is more motivated to mitigate climate change when it is framed as a health issue. Improved medical understanding of the association between climate change and conflict could strengthen mitigation efforts and increase cooperation to cope with the climate change that is now inevitable. © The Royal Society of Medicine.

    The impacts of climatic change on Canada's forestry sector are discussed, in the context of major research priorities relating to forecasting climate, forecasting forest responses, monitoring changes, mitigating effects, and understanding the forest carbon balance. There are five major concerns that affect policy decisions: effects of climatic change on forests; adaptation to climate change; impacts of changing crops on forestry; changing forestry values in changing sociological settings; and international implications of the changing climate. A scientific program to respond to climate change issues is required, and should include the following concentrations of research effort. Planning requires projections of likely future climates, and efforts should concern relations between pre-historic climates and forest ecosystems and integrating data into predictive models. Forecasting of response of forests should include tree physiology, factors controlling reforestation, variations in forest trees, effects of pollutants, damage to forests, and forest decline

    Climate science regularly makes headlines in the media, usually after an extreme weather event or a disaster, or in the wake of campaigns by think tanks about the science of climate change. In this presentation, I discuss four specific challenges that are posed to climate scientist when communicating with the public: (i) The widening gap between the scientific literacy of the public and the communication literacy of the scientists; (ii), the multiplicity of scientific information conduits; (iii), information of, and under, uncertainty; and (iv), the requirement to be precise without using technical language. It turns out that these challenges are quite generic to science communication. Climate scientists have learned from the regular international assessments they perform under the auspices of the Intergovernmental Panel on Climate Change and have accumulated a collective experience of more than 20 years. In this presentation I discuss the most important lessons learned from this experience and their relevant...

    Climate change has become a pressing environmental concern for scientists, social commentators and politicians. Previous social science research has explored media representations of climate change in various temporal and geographical contexts. Through the lens of Social Representations Theory, this article provides a detailed qualitative thematic analysis of media representations of climate change in the 1988 British broadsheet press, given that this year constitutes an important juncture in this transition of climate change from the domain of science to that of the socio-political sphere. The following themes are outlined: (i) "Climate change: a multi-faceted threat"; (ii) "Collectivisation of threat"; (iii) "Climate change and the attribution of blame"; and (iv) "Speculative solutions to a complex socio-environmental problem." The article provides detailed empirical insights into the "starting-point" for present-day disputes concerning climate change and lays the theoretical foundations for tracking the continuities and discontinuities characterising social representations of climate change in the future.

    The Environmental and climatic issues varies from continent to continent and is unique to Asia. Understanding the issues does need lot of research and study material which students may not be able to gather due to shortage of time and resources. Hence an effort is made by authors gathering there experience and academic input from renowned universities of world. Climate change is real and coping with it is major concern in coming days. Most of the books written and sold in the past need updating and customizing. The general description of climate change and world will not help the professionals and students. It needs to seen area wise as a professional will work in specific geographic area. Hence an effort is made to collect data from Asia which host most populated countries along with ecological hot spots. (orig.)

    A workshop was organised to evaluate and discuss the report 'Scientific Assessment of Climate Change (1990)' of the Intergovernmental Panel on Climate Change (IPCC). Thirty prominent Dutch experts in the field attended the workshop. The introductions and discussions held on our knowledge of climatic change as a result of the growth of the greenhouse effect caused by the emission of greenhouse gases from human actions are presented. It is concluded that the IPCC-report shows in a clear and balanced way the certainties and uncertainties in our knowledge of climate change. There is a large chance that the earth's climate will change considerably, if the policy remains unamended. 15 figs., 2 apps

    Earth's climate is inherently variable, but is currently changing at rates unprecedented in recent Earth history. Human activity plays a major role in this change and is projected to do so well into the future. This is the stance taken in Our Changing Climate, the brand new climate science ebook from the American Meteorological Society (AMS). Our Changing Climate investigates Earth's climate system, explores humans' impact on it, and identifies actions needed in response to climate change. Released in August 2014, Our Changing Climate is the result of a year's worth of intensive research and writing, incorporating the latest scientific understandings of Earth's climate system from reports such as IPCC AR5 and the Third National Climate Assessment. To encourage additional exploration of climate science information, scientific literature, from which chapter content was derived, is cited at the conclusion of each chapter. In addition, Topic In Depth sections appear throughout each chapter and lead to more extensive information related to various topics. For example, a Topic In Depth in Chapter 11 describes the effect of climate extremes on ranching enterprises in Nebraska. Climate science is multi-disciplinary and therefore Our Changing Climate covers a breadth of topics. From understanding basic statistics and geospatial tools used to investigate Earth's climate system to examining the psychological and financial reasons behind climate change denial, the AMS believes that a multi-disciplinary approach is the most effective way to increase climate literacy. Our Changing Climate is part of the AMS Climate Studies course which is intended for undergraduate-level students. Other course materials include an eInvestigations Manual and access to the RealTime Climate Portal, both of which provide weekly activities corresponding to that week's chapter content. The RealTime Climate Portal also has links to climate data as well as societal interactions and climate policy

    The journal The Lancet recently published a countdown on health and climate change. Attention was focused solely on humans. However, animals, including wildlife, livestock and pets, may also be impacted by climate change. Complementary to the high relevance of awareness rising for protecting humans against climate change, here we present a One Health approach, which aims at the simultaneous protection of humans, animals and the environment from climate change impacts (climate change adaptation). We postulate that integrated approaches save human and animal lives and reduce costs when compared to public and animal health sectors working separately. A One Health approach to climate change adaptation may significantly contribute to food security with emphasis on animal source foods, extensive livestock systems, particularly ruminant livestock, environmental sanitation, and steps towards regional and global integrated syndromic surveillance and response systems. The cost of outbreaks of emerging vector-borne zoonotic pathogens may be much lower if they are detected early in the vector or in livestock rather than later in humans. Therefore, integrated community-based surveillance of zoonoses is a promising avenue to reduce health effects of climate change.

    The changing climate is creating additional challenges in maintaining a healthy school environment in the United States (U.S.) where over 50 million people, mostly children, spend approximately a third of their waking hours. Chronic low prioritization of funds and resources to support environmental health in schools and lack of clear regulatory oversight in the U.S. undergird the new risks from climate change. We illustrate the extent of risk and the variation in vulnerability by geographic region, in the context of sparse systematically collected and comparable data particularly about school infrastructure. Additionally, we frame different resilience building initiatives, focusing on interventions that target root causes, or social determinants of health. Disaster response and recovery are also framed as resilience building efforts. Examples from U.S. Federal Region 2 (New Jersey, New York, Puerto Rico, and the U.S. Virgin Islands) and nationally are used to illustrate these concepts. We conclude that better surveillance, more research, and increased federal and state oversight of environmental factors in schools (specific to climate risks) is necessary, as exposures result in short- and long term negative health effects and climate change risks will increase over time.

    Climatic elasticity has been widely applied to assess streamflow responses to climate changes. To fully assess impacts of climate under global warming on streamflow and reduce the error and uncertainty from various control variables, we develop a four-parameter (precipitation, catchment characteristics n, and maximum and minimum temperatures) climatic elasticity method named PnT, based on the widely used Budyko framework and simplified Makkink equation. We use this method to carry out the first comprehensive evaluation of the streamflow response to potential climate change for 372 widely spread catchments in China. The PnT climatic elasticity was first evaluated for a period 1980-2000, and then used to evaluate streamflow change response to climate change based on 12 global climate models under Representative Concentration Pathway 2.6 (RCP2.6) and RCP 8.5 emission scenarios. The results show that (1) the PnT climatic elasticity method is reliable; (2) projected increasing streamflow takes place in more than 60% of the selected catchments, with mean increments of 9% and 15.4% under RCP2.6 and RCP8.5 respectively; and (3) uncertainties in the projected streamflow are considerable in several regions, such as the Pearl River and Yellow River, with more than 40% of the selected catchments showing inconsistent change directions. Our results can help Chinese policy makers to manage and plan water resources more effectively, and the PnT climatic elasticity should be applied to other parts of the world.

    This report presents the results of a survey on Europeans' attitudes towards climate change which was carried out in January and February 2009. The survey focuses on: Citizens' perceptions of climate change in relation to other world problems; Citizens' perceptions of the seriousness of climate change; The extent to which citizens feel informed about climate change - its causes, consequences and ways of fighting it; Citizens' attitudes towards alternative fuels and CO2 emissions; Whether citizens feel that climate change is stoppable or has been exaggerated, and what impact it has on the European economy; Whether citizens have taken personal action to fight climate change. This Eurobarometer survey was carried out by TNS Opinion and Social network between 16 January and 22 February 2009. The interviews were conducted among 26,718 citizens in the 27 Member States of the European Union, the three candidate countries for accession to the European Union (Croatia, Turkey and the Former Yugoslav Republic of Macedonia) and in the Turkish Cypriot Community.

    The climate issue is a great political and scientific challenge for several reasons: (1) There are many uncertain aspects of the climate problem, such as future emission of climate gases, the response of the climate system upon these gases, and the effects of climate changes. (2) It is probable, however, that anthropogenic emission of climate gases, deforestation etc. will cause noticeable climate changes in the future. This might be observed as increased frequency of extreme weather situations. This appears to be a greater threat than a gradual increase of temperature and precipitation. (3) Since the climate system is large and react only relatively slowly on changes in for instance the emission of climate gases, the climate problem can only be solved by means of long-term measures. (4) The climate changes may be irreversible. A rational short-term strategy is to ensure maximum flexibility, which can be done by ''slowing down'' (curtailing emissions) and by avoiding irreversible actions as much as possible. The long-term challenge is to develop an economically responsible alternative to the present fossil-based energy system that permits carbon-efficient technologies to compete on price with coal and unconventional oil and gas. Norway is in a special position by being a large exporter of fossil fuel and at the same time wanting to appear responsible in environmental matters. This combination may incur considerable expenses upon Norway and it is therefore important that environmental commitments like the Kyoto agreement can be honoured to the lowest possible cost. The costs can be minimized by: (1) minimizing the measure costs in Norway, (2) working to make the international quota price as low as possible, and (3) reducing the loss of petroleum income as much as possible. This report describes the earth's climate history, the forces behind climatic changes and what the prospects for the future look like. It also reviews what is being done

    Archaeology can provide insight into interactions of climate change and human activities in sensitive areas such as the Sahara, to the benefit of both disciplines. Such analyses can help set bounds on climate change projections, perhaps identify elements of tipping points, and provide constraints on models. The opportunity exists to more precisely constrain the relationship of natural solar and climate interactions, improving understanding of present and future anthropogenic forcing. We are beginning to explore the relationship of human occupation of the Sahara and long-term solar irradiance variations synergetic with changes in atmospheric-ocean circulation patterns. Archaeological and climate records for the last 12 K years are gaining adequate precision to make such comparisons possible. We employ a range of climate records taken over the globe (e.g. Antarctica, Greenland, Cariaco Basin, West African Ocean cores, records from caves) to identify the timing and spatial patterns affecting Saharan climate to compare with archaeological records. We see correlation in changing ocean temperature patterns approx. contemporaneous with drying of the Sahara approx. 6K years BP. The role of radar images and other remote sensing in this work includes providing a geographically comprehensive geomorphic overview of this key area. Such coverage is becoming available from the Japanese PALSAR radar system, which can guide field work to collect archaeological and climatic data to further constrain the climate change chronology and link to models. Our initial remote sensing efforts concentrate on the Gilf Kebir area of Egypt.

  7. Climate change: against despair

    OpenAIRE

    McKinnon, Catriona

    2014-01-01

    In the face of accelerating climate change and the parlous state of its politics, despair is tempting. This paper analyses two manifestations of despair about climate change related to (1) the inefficacy of personal emissions reductions, and (2) the inability to make a difference to climate change through personal emissions reductions. On the back of an analysis of despair as a loss of hope, the paper argues that the judgements grounding each form of despair are unsound. The paper concludes w...

    In recent years, global changes are the major causes of frequent, widespread outbreaks of pests in mosaic landscapes, which have received substantial attention worldwide. We collected data on global changes (landscape and climate) and economic damage caused by six main insect pests during 1951-2010 in China. Landscape changes had significant effects on all six insect pests. Pest damage increased significantly with increasing arable land area in agricultural landscapes. However, climate changes had no effect on damage caused by pests, except for the rice leaf roller (Cnaphalocrocis medinalis Guenee) and armyworm (Mythimna separate (Walker)), which caused less damage to crops with increasing mean temperature. Our results indicate that there is slight evidence of possible offset effects of climate changes on the increasing damage from these two agricultural pests. Landscape changes have caused serious outbreaks of several species, which suggests the possibility of the use of landscape design for the control of pest populations through habitat rearrangement. Landscape manipulation may be used as a green method to achieve sustainable pest management with minimal use of insecticides and herbicides.

    Full Text Available Since the first assessment report (FAR of Inter-Governmental Panel on Climate Change (IPCC in 1990, the international scientific community has made substantial progresses in climate change sciences. Changes in components of climate system, including the atmosphere, oceans and cryosphere, indicate that global warming is unequivocal. Instrumental records demonstrate that the global mean temperature has a significant increasing trend during the 20th century and in the latest 50 years the warming become faster. In the meantime, the global sea level has a strong increasing trend, as well as the snow coverage of Northern Hemisphere showed an obvious downward trend. Moreover, the global warming plays a key role in significantly affecting the climate system and social-economy on both global and regional scales, such as sea level rise, melting of mountain glaciers and ice sheets, desertification, deforestation, increase of weather extremes (typhoon, hurricane and rainstorm and so on. The state of the art understanding of IPCC Fourth Assessment Report (AR4 was most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in the concentrations of anthropogenic greenhouse gases. Climate change issues, as a grave challenge to the sustainable development of the human society, have received ever greater attention from the international community. Deeply cognizant of the complexity and extensive influence of these issues and fully aware of the arduousness and urgency of the task of addressing climate change, the Chinese government is determined to address climate change in the process of pursuing sustainable development. The facts of climate change in China and its impacts, and China’s policies and actions for addressing climate change are introduced in this paper.

    Extreme climatic events could be major drivers of biodiversity change, but it is unclear whether extreme biological changes are (i) individualistic (species- or group-specific), (ii) commonly associated with unusual climatic events and/or (iii) important determinants of long-term population trends. Using population time series for 238 widespread species (207 Lepidoptera and 31 birds) in England since 1968, we found that population 'crashes' (outliers in terms of species' year-to-year population changes) were 46% more frequent than population 'explosions'. (i) Every year, at least three species experienced extreme changes in population size, and in 41 of the 44 years considered, some species experienced population crashes while others simultaneously experienced population explosions. This suggests that, even within the same broad taxonomic groups, species are exhibiting individualistic dynamics, most probably driven by their responses to different, short-term events associated with climatic variability. (ii) Six out of 44 years showed a significant excess of species experiencing extreme population changes (5 years for Lepidoptera, 1 for birds). These 'consensus years' were associated with climatically extreme years, consistent with a link between extreme population responses and climatic variability, although not all climatically extreme years generated excess numbers of extreme population responses. (iii) Links between extreme population changes and long-term population trends were absent in Lepidoptera and modest (but significant) in birds. We conclude that extreme biological responses are individualistic, in the sense that the extreme population changes of most species are taking place in different years, and that long-term trends of widespread species have not, to date, been dominated by these extreme changes.This article is part of the themed issue 'Behavioural, ecological and evolutionary responses to extreme climatic events'. © 2017 The Authors.

    The effect of anthropogenic climate change on organisms will likely be related to climate change exposure and velocity at local and regional scales. However, common methods to estimate climate change exposure and velocity ignore important components of climate that are known to affect the ecology and evolution of organisms.We develop a novel index of climate change (climate overlap) that simultaneously estimates changes in the means, variation and correlation between multiple weather variables. Specifically, we estimate the overlap between multivariate normal probability distributions representing historical and current or projected future climates. We provide methods for estimating the statistical significance of climate overlap values and methods to estimate velocity using climate overlap.We show that climates have changed significantly across 80% of the continental United States in the last 32 years and that much of this change is due to changes in the variation and correlation between weather variables (two statistics that are rarely incorporated into climate change studies). We also show that projected future temperatures are predicted to be locally novel (using climate overlap compared to 1·4 km yr−1 when estimated using traditional methods.Our results suggest that accounting for changes in the means, variation and correlation between multiple weather variables can dramatically affect estimates of climate change exposure and velocity. These climate components are known to affect the ecology and evolution of organisms, but are ignored by most measures of climate change. We conclude with a set of future directions and recommend future work to determine which measures of climate change exposure and velocity are most related to biological responses to climate change.

    Biological diversity or biodiversity is crucial for ecological stability including regulation of climate change, recreational and medicinal use; and scientific advancement. Kenya like other developing countries, especially, those in Sub-Saharan Africa, will continue to depend greatly on her biodiversity for present and future development. This important resource must, therefore be conserved. This chapter presents an overview of Kenya's biodiversity; its importance and initiatives being undertaken for its conservation; and in detail, explores issues of climate change and biodiversity, concentrating on impacts of climate change

    Feedbacks of terrestrial ecosystems to climate change depend on soil ecosystem dynamics. Soil ecosystems can directly and indirectly respond to climate change. For example, warming directly alters microbial communities by increasing their activity. Climate change may also alter plant community composition, thus indirectly altering the microbial communities that feed on their inputs. To better understand how climate change may directly and indirectly alter soil ecosystem functioning, we investigated old-field plant community and soil ecosystem responses to single and combined effects of elevated [CO2], warming, and water availability. Specifically, we collected soils at the plot level (plant community soils), and beneath dominant plant species (plant-specific soils). We used microbial enzyme activities and soil nematodes as indicators for soil ecosystem functioning. Our study resulted in two main findings: 1) Overall, while there were some interactions, water, relative to increases in [CO2] and warming, had the largest impact on plant community composition, soil enzyme activities, and soil nematodes. Multiple climate change factors can interact to shape ecosystems, but in this case, those interactions were largely driven by changes in water availability. 2) Indirect effects of climate change, via changes in plant communities, had a significant impact on soil ecosystem functioning and this impact was not obvious when looking at plant community soils. Climate change effects on enzyme activities and soil nematode abundance and community structure strongly differed between plant community soils and plant-specific soils, but also within plant-specific soils. In sum, these results indicate that accurate assessments of climate change impacts on soil ecosystem functioning require incorporating the concurrent changes in plant function and plant community composition. Climate change-induced shifts in plant community composition will likely modify or counteract the direct

    Nowadays the anthropogenic climate change is been simulated world wide with a fair number of coupled ocean atmosphere general circulation models (IPCC, 1995). Typical model problems do not only blur the estimates of the anthropogenic climate change, but they also cause errors in the estimates of the natural variability. An accurate representation of the natural variability of the climate system is, however, essential for the detection of the anthropogenic climate change. All model simulations world wide show, even though they differ considerably in their technical details and the experimental setup and the forcing data, similar amplitudes and pattern of the predicted climate change. In the model world it is already at the beginning of the next century possible to detect the anthropogenic climate change in the global mean. If the model results are applied in a `fingerprint analysis`, then it is possible to prove that the climate change during the last 30 years is with a significance of 95 % larger than any other climate change during the last 100 years. The experiments performed in Hamburg show that the experimental conditions are of great importance for the estimate of the future climate. The usual starting point of most of the simulations with present day conditions (1980-1990) is too late, because then a considerable part of the warming since the beginning of the industrialization (ca. 1750) has been neglected. Furthermore it has only recently become clear that the sulphat-aerosols play an important role in the present day climate and in the future climate. The effect of the sulphat aerosols has first been simulated in a number of equilibrium simulations with mixed layer models, but nowadays with globally coupled ocean-atmosphere circulation models

    Climate change is a major environmental issue that is often discussed throughout the world using social media outlets. One major social media site that is commonly utilized by the public is Twitter, with over 300 million active users. Using a Twitter account and Ncapture we were able to collect tens of thousands of tweets around the COP21 event, a United Nations climate change conference held on Dec. 7-8, 2015 in Paris, and the 2015 Encyclical Release by the Pope, using the hashtags @climate, pope, and COP21. This research aimed to follow and collect tweets about what and who the major influencers on Twitter are concerning these events, and subsequently climate change in general, and what content was most persistent. Specifically, we examined Twitter users with high numbers of followers (>10,000), the number of re-tweets, the frequency of tweets, and the content of the tweet. We have tabulated the top 10 most influential Tweeters among each of the months (August, September, October, November and December) of 2015 leading up to and following the COP21 event, which included an array of Twitter users from NGOs, Politicians, Celebrities, Religious Leaders, Governmental Organizations, among others. We also examined tweets about climate change as they relate to the two events and interpret why these tweets may have persisted in the twitter space. From our observations, we have established some best practices in how to create climate messages that have high reach and longevity. We hope our results assist climate change communicators in understanding the role Twitter plays in regard to climate change discourse and how to most efficiently utilize it for reaching broad audiences and engaging them in the climate conversation.

    Countries in Sub-Saharan Africa are particularly vulnerable to climate change, given dependence on agricultural production and limited adaptive capacity. Based on farm household and Participatory Rural Appraisal data collected from districts in various agroecological zones in Kenya, this paper examines farmers' perceptions of climate change, ongoing adaptation measures, and factors influencing farmers' decisions to adapt. The results show that households face considerable challenges in adapting to climate change. While many households have made small adjustments to their farming practices in response to climate change (in particular, changing planting decisions), few households are able to make more costly investments, for example in agroforestry or irrigation, although there is a desire to invest in such measures. This emphasizes the need for greater investments in rural and agricultural development to support the ability of households to make strategic, long-term decisions that affect their future well-being.

    Climate archives available from deep-sea and marine shelf sediments, glaciers, lakes and ice cores in and around Greenland allow us to place the current trends in regional climate, ice sheet dynamics, and land surface changes in a broader perspective. We show that during the last decade (2000s......), atmospheric and sea-surface temperatures are reaching levels last encountered millennia ago when northern high latitude summer insolation was higher due to a different orbital configuration. Concurrently, records from lake sediments in southern Greenland document major environmental and climatic conditions...... regional climate and ice sheet dynamics. The magnitude and rate of future changes in Greenland temperature, in response to increasing greenhouse gas emissions, may be faster than any past abrupt events occurring under interglacial conditions. Projections indicate that within one century Greenland may...

    Evidence is reviewed for climate change and its causes over the interval spanning roughly the past millennium. Particular emphasis is placed on patterns of climate change influencing Mediterranean climates of the Northern Hemisphere. The evidence is taken from studies using high-resolution climate proxy data sources, and climate modeling simulations. The available evidence suggests that forced changes in dynamical modes of variability including the North Atlantic Oscillation (NAO) and El Nino/Southern Oscillation (ENSO) have played a key role in the patterns of climate variability in Mediterranean regions over the past millennium

    The potential social, economic and environmental impacts of climate change are reviewed, with emphasis on agricultural implications. Impact analyses must be done on the scale of watersheds or river basins. For agriculture, climate change effects on water resources are likely to be more important than temperature changes, and climatic variability is also equally important. Another set of critical climatic variables are the frequencies, magnitudes and timing of extreme events such as floods, droughts, etc. A carbon dioxide enriched atmosphere will increase water use efficiency and confer increased tolerance to drought, salinity and air pollution. Better understanding and accounting is required for the effects of increased carbon dioxide on all plant life, including crops. Adaptability of agriculture to change must be taken into account in predicting impacts of climate change, with technological innovation and infrastructure giving agriculture a dynamic nature. Limitations and adaptations must be considered when formulating public policy, to ensure that marginal costs do not exceed marginal benefits. Monoculture plantation forests may be the most efficient sinks of atmospheric carbon dioxide, yet widespread reliance on them may harm biological diversity. Actions the U.S. is currently taking under a no-regrets policy are summarized

    The latest scientific knowledge on climate change indicates that higher greenhouse gas concentrations in the atmosphere through unchecked emissions will provoke severe climate change and ocean acidification threatening environmental structures on which humanity relies. Climate change therefore poses major socio-economic, technical and environmental challenges which will have serious impacts on countries’ pathways towards sustainable development. As a result, climate change and sustainable development have increasingly become interlinked. A changing climate makes achieving Millennium Development Goals more difficult and expensive, so there is every reason to achieve development goals with low greenhouse gas emissions. This leads to the following five challenges discussed by Challenges and Solutions for Climate Change: To place climate negotiations in the wider context of sustainability, equity and social change so that development benefits can be maximised at the same time as decreasing greenhouse gas emissi...

    Significant efforts are underway to translate improved understanding of how climate change is altering ecosystems into practical actions for sustaining ecosystem functions and benefits. We explore this transition in California, where adaptation and mitigation are advancing relatively rapidly, through four case studies that span large spatial domains and encompass diverse ecological systems, institutions, ownerships, and policies. The case studies demonstrate the context specificity of societal efforts to adapt ecosystems to climate change and involve applications of diverse scientific tools (e.g., scenario analyses, downscaled climate projections, ecological and connectivity models) tailored to specific planning and management situations (alternative energy siting, wetland management, rangeland management, open space planning). They illustrate how existing institutional and policy frameworks provide numerous opportunities to advance adaptation related to ecosystems and suggest that progress is likely to be greatest when scientific knowledge is integrated into collective planning and when supportive policies and financing enable action.

    In the late eighties several reports have been published on climate change and sea level rise. In the meantime insights may have changed due to the availability of better and more observations and/or more advanced climate models. The aim of this report is to present the most recent findings with respect to climate change, in particular of sea level rise, storm surges and river peak flows. These climate factors are important for the safety of low-lying areas with respect to coastal erosion and flooding. In the first chapters a short review is presented of a few of the eighties reports. Furthermore, the predictions by state of the art climate models at that time are given. The reports from the eighties should be considered as 'old' information, whereas the IPCC supplement and work, for example, by Wigley should be considered as new information. To assess the latest findings two experts in this field were interviewed: dr J. Oerlemans and dr C.J.E. Schuurmans, a climate expert from the Royal Netherlands Meteorological Institute (KNMI). Their views are presented together with results published in recent papers on the subject. On the basis of this assessment, the report presents current knowledge regarding predictions of climate change (including sea-level rise) over the next century, together with an assessment of the uncertainties associated with these predictions. 14 figs., 11 tabs., 24 refs

Two complementary approaches may be distinguished: the actor-related approach analyses the positioning of states and interest groups, which develop strategies on coping with climate change; the other approach addresses processes and problem areas (physical, economic, demographic… emerging in the geographic space as a consequence of, or linked to climate change. With failing mitigation policies and instruments, the urgency of adaptation to climate change is increasing. Assessment of regional consequences of climate change includes the perceptions and motivations of presumed losers or winners. New security implications related to climate change are emerging in the Arctic, South-East Asia, Africa and the Pacific. Energy supply security is a dominant factor in geopolitical considerations. The geopolitics of climate change is inextricably linked to many other issues of globalization. Significant shift of global power raises the discussion of ethical responsibility. Climate change is evolving as a testing ground for competitiveness and innovation potential of political and economic models in achieving sustainability.

    Some investors are willing to lower the carbon emission financed by their investment, recognizing that climate change has financial impacts. At first they measure the carbon footprint of their portfolio, than initiate shareholder engagement actions at oil and gas companies, publish list of exclusion composed of the most carbon-intensive companies and ask for ex fossil fuels indices. In June 2015, Novethic launches the first actualisation of its study released on February 2015 on the mobilisation of investors on climate change over the whole 2015 year. The trend is gaining momentum since more than 200 additional investors publicly disclosed commitments to integrate climate risk into their investment and management practices. In September 2015, for its second update of the report on how investors are taking action on climate change, more than 800 entities were screened. As a key result, investor's actions gain momentum: approaches are growing in number and becoming more expert, divestments are widespread in Europe, and green investments promises are more ambitious. The last edition of November 2015 highlights and scans an exclusive panel of 960 investors worth Euro 30 trillion of assets who have made steps forward to tackle climate change. During the last 8 months, their number has almost increased twofold. This document brings together the first edition of Novethic's study and its three updates

    Full Text Available Pro-environmental behaviors and the cultural shifts that can accompany these may offer solutions to the consequences of a changing climate. Mindfulness has been proposed as a strategy to initiate these types of behaviors. In 2017, we pilot-tested Mindful Climate Action (MCA, an eight-week adult education program that delivers energy use, climate change, and sustainability content in combination with training in mindfulness meditation, among 16 individuals living in Madison, WI. We collected participant data at baseline and at different times across the study period regarding household energy use, transportation, diet, and health and happiness. This pilot study aimed to evaluate the feasibility of the various MCA study practices including measurement tools, outcome assessment, curriculum and related educational materials, and especially the mindfulness-based climate action trainings. MCA was well-received by participants as evidenced by high adherence rate, high measures of participant satisfaction, and high participant response rate for surveys. In addition, we successfully demonstrated feasibility of the MCA program, and have estimated participant’s individual carbon footprints related to diet, transportation, and household energy.

    1991-01-01

    On May 8--10, 1991, the Midwest Consortium of International Security Studies (MCISS) and Argonne National Laboratory cosponsored a conference on Global Climate Change and International Security. The aim was to bring together natural and social scientists to examine the economic, sociopolitical, and security implications of the climate changes predicted by the general circulation models developed by natural scientists. Five themes emerged from the papers and discussions: (1) general circulation models and predicted climate change; (2) the effects of climate change on agriculture, especially in the Third World; (3) economic implications of policies to reduce greenhouse gas emissions; (4) the sociopolitical consequences of climate change; and (5) the effect of climate change on global security.

    Analysis of the economic impact of climate change typically considers regional or national economies and assesses its impact on macroeconomic aggregates such as gross domestic product. These studies therefore do not investigate the distributional impacts of climate change within countries or the impacts on poverty. This Perspective aims to close this gap and provide an assessment of climate change impacts at the household level to investigate the consequences of climate change for poverty and for poor people. It does so by combining assessments of the physical impacts of climate change in various sectors with household surveys. In particular, it highlights how rapid and inclusive development can reduce the future impact of climate change on poverty.

  19. Climate change in Nova Scotia : a background paper to guide Nova Scotia's climate change action plan

    2007-10-01

    Climate change causes changes in the temperature of the earth, the level of the sea, and the frequency of extreme weather conditions. The province of Nova Scotia recently released an act related to environmental goals and sustainable prosperity. Addressing climate change is a key element in achieving Nova Scotia's sustainable prosperity goals outlined in the act. The Nova Scotia Department of Energy is working towards developing both policy and action, to help meet its target of a 10 per cent reduction in greenhouse gases from 1990 levels by the year 2020. Two major plans are underway, notably a climate change action plan and a renewed energy strategy. This report provided background information on Nova Scotia's climate change action plan. It discussed climate change issues affecting Nova Scotia, air pollutants, energy sources in Nova Scotia, energy consumers in the province, and Nova Scotia's approach to climate change. The report also discussed actions underway and funding sources. It was concluded that in order for the climate change action plan to be successful, Nova Scotians must use energy more efficiently; use renewable energy; use cleaner energy; and plan for change. 13 refs., 2 tabs., 6 figs., 4 appendices

    Starting with the US-USSR Agreement on Protection of the Environment signed in 1972, the two nations have cooperated in joint research on atmospheric and environmental problems. The result of these efforts has been an innovative approach to projecting future climate change based on what has been learned about past warm periods and what can be learned from models. The chapters in this document explore the following: past changes in climate, both paleoclimatology and changes in the recent past; changes in atmospheric composition; estimates of greenhouse-induced change including the use of both empirical methods and climate models; impacts of climate change on water resources and agriculture in the two countries; and prospects for future climate changes

    Schuenemann, K. C.; Wagner, R.

    2011-12-01

    In fall 2011 a pilot course on "Global Climate Change" is being offered, which has been proposed to educate urban, diverse, undergraduate students about climate change at the introductory level. The course has been approved to fulfill two general college requirements, a natural sciences requirement that focuses on the scientific method, as well as a global diversity requirement. This course presents the science behind global climate change from an Earth systems and atmospheric science perspective. These concepts then provide the basis to explore the effect of global warming on regions throughout the world. Climate change has been taught as a sub-topic in other courses in the past solely using scientific concepts, with little success in altering the climate change misconceptions of the students. This pilot course will see if new, innovative projects described below can make more of an impact on the students' views of climate change. Results of the successes or failures of these projects will be reported, as well as results of a pre- and post-course questionnaire on climate change given to students taking the course. Students in the class will pair off and choose a global region or country that they will research, write papers on, and then represent in four class discussions spaced throughout the semester. The first report will include details on the current climate of their region and how the climate shapes that region's society and culture. The second report will discuss how that region is contributing to climate change and/or sequestering greenhouse gases. Thirdly, students will discuss observed and predicted changes in that region's climate and what impact it has had, and could have, on their society. Lastly, students will report on what role their region has played in mitigating climate change, any policies their region may have implemented, and how their region can or cannot adapt to future climate changes. They will also try to get a feel for the region

  2. Examining the potential impacts of climate change on international security: EU-Africa partnership on climate change.

    2014-01-01

    Climate Change like many global problems nowadays is recognized as a threat to the international security and cooperation. In theoretical terms, it is being securitized and included in the traditional security studies. Climate change and its accompanying environmental degradation are perceived to be a threat that can have incalculable consequences on the international community. The consequences are said to have more effects in small island developing nations and Africa where many States are fragile and overwhelmed with mounting challenges. In recent years, the security implications of the climate change are being addressed from national, regional and multilateral level. Against this backdrop, this paper intends to contribute to the debate on climate change and international security and present a broader perspective on the discussion. The paper will draw from the EU-Africa partnership on climate change and is structured as follows: the first part introduces the background of the international climate change policy and its securitization, the second part covers the EU-Africa relations and EU-Africa partnership on climate change, and the third part discusses the Congo Basin Forest Partnership as a concrete example of EU-Africa Partnership on Climate Change. Lastly, the paper concludes by drawing some conclusions and offers some policy perspectives and recommendations. Q54; 055; 052; 01;

    2007-01-01

    This article explores the international dimensions of multinationals' corporate political activities, focusing on an international issue - climate change - being implemented differently in a range of countries. Analyzing data from Financial Times Global 500 firms, it examines the influence on types and process of multinationals' political strategies, reckoning with institutional contexts and issue saliency. Findings show that the type of political activities can be characterized as an information strategy to influence policy makers toward market-based solutions, not so much withholding action on emission reduction. Moreover, multinationals pursue self-regulation, targeting a broad range of political actors. The process of political strategy is mostly one of collective action. International differences particularly surface in the type of political actors aimed at, with U.S. and Australian firms focusing more on non-government actors (voluntary programs) than European and Japanese firms. Influencing home-country (not host-country) governments is the main component of international political strategy on climate change

    2016-01-01

    Do forest owners' levels of education or value profiles explain their responses to climate change? The cultural cognition thesis (CCT) has cast serious doubt on the familiar and often criticized "knowledge deficit" model, which says that laypeople are less concerned about climate change because they lack scientific knowledge. Advocates of CCT maintain that citizens with the highest degrees of scientific literacy and numeracy are not the most concerned about climate change. Rather, this is the group in which cultural polarization is greatest, and thus individuals with more limited scientific literacy and numeracy are more concerned about climate change under certain circumstances than those with higher scientific literacy and numeracy. The CCT predicts that cultural and other values will trump the positive effects of education on some forest owners' attitudes to climate change. Here, using survey data collected in 2010 from 766 private forest owners in Sweden and Germany, we provide the first evidence that perceptions of climate change risk are uncorrelated with, or sometimes positively correlated with, education level and can be explained without reference to cultural or other values. We conclude that the recent claim that advanced scientific literacy and numeracy polarizes perceptions of climate change risk is unsupported by the forest owner data. In neither of the two countries was university education found to reduce the perception of risk from climate change. Indeed in most cases university education increased the perception of risk. Even more importantly, the effect of university education was not dependent on the individuals' value profile.

    The population of the Southeastern United States is perceived to be resistant to information regarding global climate change. The Climate Literacy Partnership in the Southeast (CLiPSE) project was formed to provide a resource for climate science information. As part of this project, we are evaluating the way that education materials influence the interpretation of climate change related information. At Mississippi State University, a study is being conducted examining how individuals from the Southeastern United States process climate change information and whether or not the interaction with such information impacts the interpretation of subsequent climate change related information. By observing the patterns both before and after an educational intervention, we are able to evaluate the effectiveness of the climate change information on an individual's interpretation of related information. Participants in this study view figures describing various types of climate change related information (CO2 emissions, sea levels, etc.) while their eye movements are tracked to determine a baseline for the way that they process this type of graphical data. Specifically, we are examining time spent viewing and number of fixations on critical portions of the figures prior to exposure to an educational document on climate change. Following the baseline period, we provide participants with portions of a computerized version of Climate Literacy: The Essential Principles of Climate Sciences that the participants read at their own pace while their eye movements are monitored. Participants are told that they will be given a test on the material after reading the resource. After reading the excerpt, participants are presented with a new set of climate change related figures to interpret (with eye tracking) along with a series of questions regarding information contained in the resource. We plan to evaluate changes that occur in the way that climate change related information is

    Mulenga, Brian P; Wineman, Ayala; Sitko, Nicholas J

    2017-02-01

    A number of studies use meteorological records to analyze climate trends and assess the impact of climate change on agricultural yields. While these provide quantitative evidence on climate trends and the likely effects thereof, they incorporate limited qualitative analysis of farmers' perceptions of climate change and/or variability. The present study builds on the quantitative methods used elsewhere to analyze climate trends, and in addition compares local narratives of climate change with evidence found in meteorological records in Zambia. Farmers offer remarkably consistent reports of a rainy season that is growing shorter and less predictable. For some climate parameters-notably, rising average temperature-there is a clear overlap between farmers' observations and patterns found in the meteorological records. However, the data do not support the perception that the rainy season used to begin earlier, and we generally do not detect a reported increase in the frequency of dry spells. Several explanations for these discrepancies are offered. Further, we provide policy recommendations to help farmers adapt to climate change/variability, as well as suggestions to shape future climate change policies, programs, and research in developing countries.

Documenting the extent of these impacts requires quantitative tools for analyses of ecological observations to distinguish climate impacts in noisy data and to understand interactions between...... climate variability and other drivers of change. To assist the development of reliable statistical approaches, we review the marine climate change literature and provide suggestions for quantitative approaches in climate change ecology. We compiled 267 peer‐reviewed articles that examined relationships...

  12. Creationism & Climate Change (Invited)

    Science.gov (United States)

    Newton, S.

    2009-12-01

    Although creationists focus on the biological sciences, recently creationists have also expanded their attacks to include the earth sciences, especially on the topic of climate change. The creationist effort to deny climate change, in addition to evolution and radiometric dating, is part of a broader denial of the methodology and validity of science itself. Creationist misinformation can pose a serious problem for science educators, who are further hindered by the poor treatment of the earth sciences and climate change in state science standards. Recent changes to Texas’ science standards, for example, require that students learn “different views on the existence of global warming.” Because of Texas’ large influence on the national textbook market, textbooks presenting non-scientific “different views” about climate change—or simply omitting the subject entirely because of the alleged “controversy”—could become part of K-12 classrooms across the country.

    2013-02-01

    Full Text Available This article explores the impact of climate change and variability on agricultural productivity in the communal area of Bikita. The article further examines the adaptation and mitigation strategies devised by farmers to deal with the vagaries of climate change and variability. The sustainability of these is also interrogated in this article. This study juxtaposed qualitative and quantitative methodologies albeit with more bias on the former. A total of 40 farmers were sampled for unstructured interviews and focus group discussions. This article argues that the adverse impacts of climate change and variability are felt heavily by the poor communal farmers who are directly dependent on agriculture for livelihood. From the study, some of the widely reported signs of climate variability in Bikita included late and unpredictable rains, high temperatures (heat waves, successive drought, shortening rainfall seasons and seasonal changes in the timing of rainfall. The paper argues that climate change has compounded the vulnerability of peasant farmers in the drought - prone district of Bikita plunging them into food insecurity and abject poverty. It emerged in the study that some of effects of climate variability felt by communal farmers in Bikita included failure of crops, death of livestock and low crop yields, all of which have led to declining agricultural productivity. Findings in this study however established that communal farmers have not been passive victims of the vagaries of climate change and variability. They have rationally responded to it through various adaptation and mitigation strategies both individually and collectively.

    As stated at the beginning of this chapter, the relationship between transportation and climate is two-directional. Based on our statistical analysis performed for Canada, we can make some general conclusions about this relationship. On the one hand, transportation is one of the largest contributors to GHG emissions which, in turn, cause various changes in climate. On the other hand, these climate changes negatively affect transportation in terms of its infrastructure and operations. Therefor...

    2007-12-11

    The strong trends in climate change already evident, the likelihood of further changes occurring, and the increasing scale of potential climate impacts give urgency to addressing agricultural adaptation more coherently. There are many potential adaptation options available for marginal change of existing agricultural systems, often variations of existing climate risk management. We show that implementation of these options is likely to have substantial benefits under moderate climate change for some cropping systems. However, there are limits to their effectiveness under more severe climate changes. Hence, more systemic changes in resource allocation need to be considered, such as targeted diversification of production systems and livelihoods. We argue that achieving increased adaptation action will necessitate integration of climate change-related issues with other risk factors, such as climate variability and market risk, and with other policy domains, such as sustainable development. Dealing with the many barriers to effective adaptation will require a comprehensive and dynamic policy approach covering a range of scales and issues, for example, from the understanding by farmers of change in risk profiles to the establishment of efficient markets that facilitate response strategies. Science, too, has to adapt. Multidisciplinary problems require multidisciplinary solutions, i.e., a focus on integrated rather than disciplinary science and a strengthening of the interface with decision makers. A crucial component of this approach is the implementation of adaptation assessment frameworks that are relevant, robust, and easily operated by all stakeholders, practitioners, policymakers, and scientists.

  17. Evaluating Successful Livelihood Adaptation to Climate Variability and Change in Southern Africa

    Directory of Open Access Journals (Sweden)

    Henny Osbahr

    2010-06-01

    Full Text Available This paper examines the success of small-scale farming livelihoods in adapting to climate variability and change. We represent adaptation actions as choices within a response space that includes coping but also longer-term adaptation actions, and define success as those actions which promote system resilience, promote legitimate institutional change, and hence generate and sustain collective action. We explore data on social responses from four regions across South Africa and Mozambique facing a variety of climate risks. The analysis suggests that some collective adaptation actions enhance livelihood resilience to climate change and variability but others have negative spillover effects to other scales. Any assessment of successful adaptation is, however, constrained by the scale of analysis in terms of the temporal and spatial boundaries on the system being investigated. In addition, the diversity of mechanisms by which rural communities in southern Africa adapt to risks suggests that external interventions to assist adaptation will need to be sensitive to the location-specific nature of adaptation.

    There is a growing recognition that mitigation measures for limiting future global changes in climate due to the enhanced greenhouse effect are unlikely to prevent some changes from occurring. Thus, if climate changes appear to be unavoidable, there is an increased need to evaluate their likely impacts on natural systems and human activities. Most impacts of climate change need to be examined at a regional scale, and their assessment requires up-to-date information on future regional climate changes. Unfortunately, accurate predictions of regional climate are not yet available. Instead, it is customary to construct climatic scenarios, which are plausible representations of future climate based on the best available information. This presentation outlines seven principles of climatic scenario development for impact studies, briefly describing some of the strengths and weaknesses of available methods and then illustrating one approach adopted in Finland

    2002-08-01

    After the introduction Chapter 2 presents details of the ecological-economic analysis based on the FAO/IIASA agro-ecological zones (AEZ) approach for evaluation of biophysical limitations and agricultural production potentials, and IIASA's Basic Linked System (BLS) for analyzing the world's food economy and trade system. The BLS is a global general equilibrium model system for analyzing agricultural policies and food system prospects in an international setting. BLS views national agricultural systems as embedded in national economies, which interact with each other through trade at the international level. The combination of AEZ and BLS provides an integrated ecological-economic framework for the assessment of the impact of climate change. We consider climate scenarios based on experiments with four General Circulation Models (GCM), and we assess the four basic socioeconomic development pathways and emission scenarios as formulated by the Intergovernmental Panel on Climate Change (IPCC) in its Third Assessment Report. Chapter 3 presents the main AEZ results of the impact of climate change on agriculture. Results comprise environmental constraints to crop agriculture; climate variability and the variability of rain-fed cereal production; changes in potential agricultural land; changes in crop-production patterns; and the impact of climate change on cereal-production potential. Chapter 4 discusses the AEZ-BLS integrated ecological-economic analysis of climate change on the world food system. This includes quantification of scale and location of hunger, international agricultural trade, prices, production, land use, etc. It assesses trends in food production, trade, and consumption, and the impact on poverty and hunger of alternative development pathways and varying levels of climate change. Chapter 5 presents the main conclusions and policy implications of this study

We argue that the key justice dilemmas of adaptation include responsibility for climate change impacts, the level and burden sharing of assistance to vulnerable countries for adaptation, distribution of assistance between recipient countries and adaptation measures, and fair participation in planning and making decisions on adaptation. We demonstrate how the climate change regime largely omits responsibility but makes a general commitment to assistance. However, the regime has so far failed to operationalise assistance and has made only minor progress towards eliminating obstacles for fair participation. We propose the adoption of four principles for fair adaptation in the climate change regime. These include avoiding dangerous climate change, forward-looking responsibility, putting the most vulnerable first and equal participation of all. We argue that a safe maximum standard of 400-500 ppm of CO 2 concentrations in the atmosphere and a carbon tax of $20-50 per carbon equivalent ton could provide the initial instruments for operationalising the principles.

    During 2009, the Technical University of Denmark (DTU) has held a number of international workshops for climate change. Participants came from industry, research institutions and government. The workshops focused on sustainable energy systems and climate change adaptation. The summary of conclusions and recommendations from the workshops constitutes a comprehensive set of technology tracks and recommended actions towards accelerated development and deployment of technology within these two key areas. The workshop process has led to three main conclusions. A. Radical changes are needed to develop sustainable energy systems. B. Tools and processes that climate-proof societal planning and management are needed in order to adapt to climate change. C. Partnerships concerning innovation and deployment (research, development and deployment) are required to meet time constraints.

    Perhaps the most startling aspect of the debate on climate change is the speed with which it has climbed the international political agenda. In 1985, climate change was viewed almost entirely as a scientific issue. Only seven years later, most industrialized countries have made some sort of political pledge to abate their emissions of greenhouse gases over a specific timetable. And earlier this year, 154 countries signed a Framework Convention on Climate Change at the UN Conference on Environment and Development in Rio de Janeiro. What is the present 'state of play' in the economics of climate change. And what priorities are now emerging in 'post-Rio' policy. 11 ref

  10. Chinese Tourists’ Perceptions of Climate Change and Mitigation Behavior: An Application of Norm Activation Theory

    Full Text Available It is well recognized that tourism development is a prominent contributor to climate change, but is also a “victim” of climate change. Therefore, to mitigate climate change is of great importance for the sustainability of tourism. Yet extant studies regarding tourism and climate change tend to be dominated by a supply-side stance, albeit the core role of the tourist in the tourism industry. While researchers are increasingly adopting a tourist perspective, few seek to understand the linkage between climate change and tourists’ specific mitigation behaviors in a tourism context; this is especially so in China. This study investigates the impact of Chinese tourists’ perceptions of climate change on their mitigation behaviors based on norm activation theory. Drawing on 557 self-administrated questionnaires collected in China, it finds that tourists’ perceptions of climate change and perceived contribution of tourism to climate change both positively affect energy saving and carbon reduction behavior in tourism. Yet, compared with perceived contribution of tourism to climate change, tourists’ perceptions of climate change are found to be a much stronger predictor for energy saving and carbon reduction behavior. Therefore, it suggests that tourists’ perceptions of climate change in a general context is more strongly related to climate change mitigation behavior in tourism, calling for attention to go beyond the tourism context to alleviate the negative impacts of tourism on climate change.

    Global changes affecting the earth are at the forefront of public interest, possibly caused by climate alterations amongst other things. The public expects appropriate measures from politics to successfully adapt to unavoidable climate changes. As well as an investigation into the causes of climatic changes and the corollaries between the different scientific phenomena, the effects on the economy and society must also be examined. The Federal Minister for Research and Technology aims to make a valuable German contribution to international Global Change Research with the focal point ''Effects of Climate Changes on the Ecological and Civil System''. The aim of the workshop was to give an outline of current scientific knowledge, sketch out research requirements and give recommendations on the focal point with regard to the BMFT. (orig.) [de

    Climate change, a quintessential environmental problem, is generally recognised as the most important development challenge in the 21st century (IPCC, 2014). In addition to acknowledging its many significant direct consequences, climate change is increasingly used to frame discussions on other important global challenges, such as health, energy and food security. This chapter provides understanding of the intricate and complex relationship between climate change, environment and development.

    2013-01-01

    This paper presents a case for compensation of actual harm from climate change in the poorest countries. First, it is shown that climate change threatens to reverse the fight to eradicate poverty. Secondly, it is shown how the problems raised in the literature for compensation to some extent...... are based on misconceptions and do not apply to compensation of present actual harm. Finally, two arguments are presented to the effect that, in so far as developed countries accept a major commitment to mitigate climate change, they should also accept a commitment to address or compensate actual harm from...... climate change. The first argument appeals to the principle that if it is an injustice to cause risk of incurring harm in the future, then it is also an injustice to cause a similar harm now. The second argument appeals to the principle that if there is moral reason to reduce the risk of specific harms...

  14. Technologies for climate change adaptation. The water sector

    This guidebook aims to provide expert information on the technologies most relevant for climate change adaptation in the water sector in developing countries. It is meant to be a practical tool for use by a broad range of stakeholders, including those in governmental agencies, water utilities, community water boards, non-governmental organizations, and private sector companies. Adaptation is an essential element of human response to climate change. The adverse impacts of climate change on the water sector will be experienced worldwide and are often projected to be most severe in resource-poor countries. Therefore, it is necessary to have access to a diverse array of adaptation technologies and practices that are appropriate and affordable in various contexts. The scale of these adaptation technologies/practices should range from the individual household level (e.g. household water treatment), to the community scale (e.g. rainwater collection in small reservoirs), to large facilities that can benefit a city or region (e.g. a desalination plant). The guidebook first reviews the projected impacts of climate change on the water sector. It then addresses the role of adaptation in the water sector and six typologies under which available strategies are categorized. Eleven technologies and practices are given detailed treatment in this guidebook and four others are covered briefly. While these do not constitute all of the adaptation technologies available in the water sector, they do represent many of the most important adaptation technologies for developing countries. For each of the 11 adaptation technologies and practices, the following are addressed: basic description, contribution to climate change and development, institutional and capacity building requirements, costs, barriers and opportunities for implementation, and extensive reference to external resources and case studies. The practical steps and appropriate contexts for implementation are covered in the

    2010-12-01

    Soil-transmitted helminthiases (STHs) collectively cause the highest global burden of parasitic disease after malaria and are most prevalent in the poorest communities, especially in sub-Saharan Africa. Climate change is predicted to alter the physical environment through cumulative impacts of warming and extreme fluctuations in temperature and precipitation, with cascading effects on human health and wellbeing, food security and socioeconomic infrastructure. Understanding how the spectrum of climate change effects will influence STHs is therefore of critical importance to the control of the global burden of human parasitic disease. Realistic progress in the global control of STH in a changing climate requires a multidisciplinary approach that includes the sciences (e.g. thermal thresholds for parasite development and resilience) and social sciences (e.g. behavior and implementation of education and sanitation programs).

    This review concerns the Quaternary climate with an emphasis on the last 200 000 years. The present state of art in this field is described and evaluated. The review builds on a thorough examination of classic and recent literature. General as well as detailed patterns in climate are described and the forcing factors and feed-back effects are discussed. Changes in climate occur on all time-scales. During more than 90% of the Quaternary period earth has experienced vast ice sheets, i.e. glaciations have been more normal for the period than the warm interglacial conditions we face today. Major changes in climate, such as the 100 000 years glacial/interglacial cycle, are forced by the Milankovitch three astronomical cycles. Because the cycles have different length climate changes on earth do not follow a simple pattern and it is not possible to find perfect analogues of a certain period in the geological record. Recent discoveries include the observation that major changes in climate seem to occur at the same time on both hemispheres, although the astronomical theory implies a time-lag between latitudes. This probably reflects the influence of feed-back effects within the climate system. Another recent finding of importance is the rapid fluctuations that seem to be a normal process. When earth warmed after the last glaciation temperature jumps of up to 10 deg C occurred within less than a decade and precipitation more than doubled within the same time. The forcing factors behind these rapid fluctuations are not well understood but are believed to be a result of major re-organisations in the oceanic circulation. Realizing that nature, on its own, can cause rapid climate changes of this magnitude put some perspective on the anthropogenic global warming debate, where it is believed that the release of greenhouse gases will result in a global warming of a few C.

    This work is an environmental education program of 50 hours- off curriculum, currently run by High school of Nikaia - Larissas. I as coordinator teacher, another two teachers and 24 students participate in this program. Intended learning outcomes: students will be able to define the importance of climate change, to evaluate the effect of human activities on climate, and to recognize the role of recycling in preventing global climate change. It is an environmental program with social goals. That means students have to understand the link between human and environment and learn how to combine environmental protection with human help. As a consequence collaboration has already begun between High school of Nikaia and the Paraplegic & Physically Disabled Association of Pella-Greece. This is a nonprofit association that collects plastic caps; with the contribution of a recycling company the Paraplegic Association converts plastic caps in wheelchairs and gives them to needy families. So, recycling caps becomes a meaningful form of environmental and social activism. Students are educated about the meaning of recycling and encouraged to collect all types of plastic caps; they are also educated in the meaning of helping people. Further, this environmental education program consists of two parts, a theoretical and a practical one: a) Theoretical part: education is an essential element of the global response to climate change, so students have to research on climate change; they visit the Center for Environmental Education in Florina and experience the aquatic ecosystem of Prespa lakes; specialists of the Centre inform students about the effects of climate change on wetlands; students have further to research how recycling can help fight global climate change as well as examine how recycling a key component of modern waste reduction is, as the third component of the "Reduce, Reuse, Recycle" waste hierarchy; they discover the interdependence of society, economy and the natural

    This paper examines factors influencing behavioural change among smallholder farmers towards adaptation to climate change in transitional climatic zones of Africa, specifically, Hwedza District in Zimbabwe. Data for this study were collected from 400 randomly-selected smallholder farmers, using a structured questionnaire, focus group discussions and key informant interviews. The study used an ordered logit model to examine the factors that influence smallholder farmers' behavioural intention towards adaptation to climate change. Results from the study show that the gender of the household head, access to extension services on crop and livestock production, access to climate information, membership to social groups and experiencing a drought have a positive influence on farmers' attitude towards adaptation to climate change and variability. The study concluded that although the majority of smallholder farmers perceive that the climate is changing, they continue to habour negative attitudes towards prescribed climate change adaptation techniques. This study recommends more education on climate change, as well as adaptation strategies for both agricultural extension workers and farmers. This can be complemented by disseminating timely climate information through extension officers and farmers' groups. Copyright © 2017 Elsevier Ltd. All rights reserved.

    According to the United Nations Framework Convention on Climate Change (UNFCCC), climate change is attributed directly or indirectly to human activities that alter the composition of the global atmosphere. It is a phenomenon that is still inadequately understood by the general public. Planners, policy makers and even within institutions of learning, but one which is bound to affect our environment and development activities. There is therefore need for information dissemination, systematic research, policy formulation, and development of strategies for managing climate change.

    Climate change poses a significant threat to human health. Understanding how climate science can be translated into public health practice is an essential first step in enabling robust adaptation and improving resiliency to climate change. Recent research highlights the importance of iterative approaches to public health adaptation to climate change, enabling uncertainties of health impacts and barriers to adaptation to be accounted for. There are still significant barriers to adaptation, which are context-specific and thus present unique challenges to public health practice. The implementation of flexible adaptation approaches, using frameworks targeted for public health, is key to ensuring robust adaptation to climate change in public health practice. The BRACE framework provides an excellent approach for health adaptation to climate change. Combining this with the insights provided and by the adaptation pathways approach allows for more deliberate accounting of long-term uncertainties. The mainstreaming of climate change adaptation into public health practice and planning is important in facilitating this approach and overcoming the significant barriers to effective adaptation. Yet, the immediate and future limits to adaptation provide clear justification for urgent and accelerated efforts to mitigate climate change.

    In this work we introduce the rationale behind the ongoing compilation of a parallel measurements database, in the framework of the International Surface Temperatures Initiative (ISTI) and with the support of the World Meteorological Organization. We intend this database to become instrumental for a better understanding of inhomogeneities affecting the evaluation of long-term changes in daily climate data. Long instrumental climate records are usually affected by non-climatic changes, due to, e.g., (i) station relocations, (ii) instrument height changes, (iii) instrumentation changes, (iv) observing environment changes, (v) different sampling intervals or data collection procedures, among others. These so-called inhomogeneities distort the climate signal and can hamper the assessment of long-term trends and variability of climate. Thus to study climatic changes we need to accurately distinguish non-climatic and climatic signals. The most direct way to study the influence of non-climatic changes on the distribution and to understand the reasons for these biases is the analysis of parallel measurements representing the old and new situation (in terms of e.g. instruments, location, different radiation shields, etc.). According to the limited number of available studies and our understanding of the causes of inhomogeneity, we expect that they will have a strong impact on the tails of the distribution of air temperatures and most likely of other climate elements. Our abilities to statistically homogenize daily data will be increased by systematically studying different causes of inhomogeneity replicated through parallel measurements. Current studies of non-climatic changes using parallel data are limited to local and regional case studies. However, the effect of specific transitions depends on the local climate and the most interesting climatic questions are about the systematic large-scale biases produced by transitions that occurred in many regions.

    Human interference with the climate system is occurring (WGI AR5 SPM Section D.3; WGI AR5 Sections 2.2, 6.3, 10.3 to 10.6, 10.9). Climate change poses risks for human and natural systems. The assessment of impacts, adaptation, and vulnerability in the Working Group II contribution to the IPCC’s Fifth Assessment Report (WGII AR5) evaluates how patterns of risks and potential benefits are shifting due to climate change. It considers how impacts and risks related to climate change can be reduced and managed through adaptation and mitigation. The report assesses needs, options, opportunities, constraints, resilience, limits, and other aspects associated with adaptation. It recognizes that risks of climate change will vary across regions and populations, through space and time, dependent on myriad factors including the extent of adaptation and mitigation. For the past 2 decades, IPCC’s Working Group II has developed assessments of climate change impacts, adaptation, and vulnerability. The WGII AR5 builds from the WGII contribution to the IPCC’s Fourth Assessment Report (WGII AR4), published in 2007, and the Special Report on Managing the Risks of Extreme Events and Disasters to Advance Climate Change Adaptation (SREX), published in 2012. It follows the Working Group I contribution to the AR5. The WGII AR5 is presented in two parts (Part A: Global and Sectoral Aspects, and Part B: Regional Aspects), reflecting the expanded literature basis and multidisciplinary approach, increased focus on societal impacts and responses, and continued regionally comprehensive coverage. [1.1 to 1.3] The number of scientific publications available for assessing climate change impacts, adaptation, and vulnerability more than doubled between 2005 and 2010, with especially rapid increases in publications related to adaptation, allowing for a more robust assessment that supports policymaking (high confidence). The diversity of the topics and regions covered has similarly expanded, as has

    Because studies of the regional impact of climate change need higher spatial resolution than that obtained in standard global climate change scenarios, developing regional scenarios from models is a crucial goal for the climate modelling community. The zoom capacity of ARPEGE-Climat, the Meteo-France climate model, allows use of scenarios with a horizontal resolution of about 50 km over France and the Mediterranean basin. An IPCC-A2 scenario for the end of the 21. century in France shows higher temperatures in each season and more winter and less summer precipitation than now. Tuning the modelled statistical distributions to observed temperature and precipitation allows us to study changes in the frequency of extreme events between today's climate and that at the end of century. The frequency of very hot days in summer will increase. In particular, the frequency of days with a maximum temperature above 35 deg C will be multiplied by a factor of 10, on average. In our scenario, the Toulouse area and Provence might see one quarter of their summer days with a maximum temperature above 35 deg C. (author)

    Repeated warnings by the scientific community on the dire consequences of climate change through global warming to the ecology and sustenance of our planet have not been give appropriate attention by the U.S. public. Research has shown that climate change is responsible for catastrophic weather occurrences--such as floods, tornadoes, hurricanes, and heat waves--resulting in environmental and public health issues. The purpose of this report is to examine factors influencing public views on climate change. Theoretical and political perspectives are examined to unpack opinions held by the public in the U.S. on climate change. The Health Belief Model is used as an example to showcase the efficacy of an individual behavior change program in providing the synergy to understand climate change at the microlevel. The concept of reframing is discussed as a strategy to alter how the public views climate change.

    Climate change will make it increasingly difficult to achieve and sustain development goals. This is largely because climate effects on poverty remain poorly understood, and poverty reduction strategies do not adequately support climate resilience. Ensuring effective development in the face of climate change requires action on six fronts: investing in a stronger climate and poverty evidence base; applying the learning about development effectiveness to how we address adaptation needs; supporting nationally derived, integrated policies and programmes; including the climate-vulnerable poor in developing strategies; and identifying how mitigation strategies can also reduce poverty and enable adaptation.

    To discuss the nature of climate change and both its immediate and long-term effects on human respiratory health. This review is based on information from a presentation of the American College of Chest Physicians course on Occupational and Environmental Lung Disease held in Toronto, Canada, June 2013. It is supplemented by a PubMed search for climate change, global warming, respiratory tract diseases, and respiratory health. It is also supplemented by a search of Web sites including the Environmental Protection Agency, National Oceanic and Atmospheric Administration, World Meteorological Association, National Snow and Ice Data Center, Carbon Dioxide Information Analysis Center, Inter-Governmental Panel on Climate Change, and the World Health Organization. Health effects of climate change include an increase in the prevalence of certain respiratory diseases, exacerbations of chronic lung disease, premature mortality, allergic responses, and declines in lung function. Climate change, mediated by greenhouse gases, causes adverse health effects to the most vulnerable patient populations-the elderly, children, and those in distressed socioeconomic strata.

    Full Text Available Women play a crucial role in many activities essential for coping with climate change. Indian women appear to be more vulnerable than men to differential impacts of climate change because they share most of the household managing responsibilities but have limited access to participation in decision making and governance. Most of the policies for climate change adaptation and mitigation do not specifically address the vulnerability of women. The National Action Plan for Climate Change (NAPCC, formulated to shape future discourse of climate change adaptation and development, recognizes the differential impacts of climate change on society, but incorporates merely a few gender specific measures. The paper suggests gender specific measures for each mission of the NAPCC to make the adaptation and development process more inclusive and sustainable in India.

  12. Climate Change Adaptation Strategies and Farm-level Efficiency in Food Crop Production in Southwestern, Nigeria

    Directory of Open Access Journals (Sweden)

    Otitoju, MA.

    2014-01-01

    Full Text Available Food crop yields depend largely on prevailing climate conditions, especially in Africa, where rain-fed agriculture predominate. The extent to which climate impacts are felt depends principally on the adaptation measures used by farmers. This study focused on the effect of climate change adaptation strategies on farm-level technical efficiency. The study used primary data collected from 360 randomly selected farmers in Southwest Nigeria. Cobb-Douglass stochastic frontier production model was used to analyse the data. Multiple cropping, land fragmentation, multiple planting dates, mulching and cover cropping were the major climate change adaptation strategies employed by the farmers. While land fragmentation and multiple planting dates had significant positive relationships, years of climate change awareness and social capital had significant inverse relationships, with technical inefficiency. This may be because while land fragmentation may hinder farm mechanization, multiple planting dates may increase the monotonousness and drudgery of farming. On the other hand, social capital and climate change awareness could help ameliorate the effects of, particularly, land fragmentation through resource pooling. It is therefore recommended that the farmers be encouraged to form cooperative societies so as to leverage their resource status through collective efforts.

    2017-06-01

    Full Text Available This paper highlights some features characterizing the representation of climate change by Spanish society, paying special attention to its assessment of the risk for people and its potential threat to health.A series of opinion polls conducted in Spain in 2008, 2010 and 2012 were used to learn about the assessments of the risks derived from climate change for different time (current generations – future generations, economic (rich countries - poor countries and proximity-to-the-polled-person (Spanish society - your community - your family - you personally scenarios. The analysis of the data collected reveals there are different “styles” of risk assessment, four characteristic groups being described: “unconcerned”, “distant”, “aware” and “alarmed”.The paper also analyses the opinions of the people who where polled on the impacts of climate change on their own health, focusing on the future likelihood of their suffering health problems. Most people thought their health could be affected at some point in the future and that climate change will increase the likelihood of suffering certain illnesses, such as allergies, asthma and respiratory diseases.Nevertheless, it is difficult to know whether an awareness of climate change risks and their effects on health will bring about in the short term new attitudes and behaviours aimed at limiting the perceived threats, given how unimportant climate change is for Spanish society in practice.

    Effective adaptation to impacts of climate change requires best-available information. To be most useful, this information should be easily found, well-documented, and translated into tools that decision-makers use and trust. To meet these needs, the President's Climate Action Plan includes efforts to develop "actionable climate science". The Climate Data Initiative (CDI) leverages the Federal Government's extensive, open data resources to stimulate innovation and private-sector entrepreneurship in support of actions to prepare for climate change. The Initiative forges commitments and partnerships from the private, NGO, academic, and public sectors to create data-driven tools. Open data from Federal agencies to support this innovation is available on Climate.Data.gov, initially focusing on coastal flooding but soon to expand to topics including food, energy, water, energy, transportation, and health. The Climate Resilience Toolkit (CRT) will facilitate access to data-driven resilience tools, services, and best practices, including those accessible through the CDI. The CRT will also include access to training and tutorials, case studies, engagement forums, and other information sources. The Climate Action Plan also calls for a public-private partnership on extreme weather risk, with the goal of generating improved assessments of risk from different types of extreme weather events, using methods and data that are transparent and accessible. Finally, the U.S. Global Change Research Program and associated agencies work to advance the science necessary to inform decisions and sustain assessments. Collectively, these efforts represent increased emphasis across the Federal Government on the importance of information to support climate resilience.

  19. Climate change: Factors and forecasts

    Wilson, W.R.

    1990-01-01

    An overview is presented of global climatic change. The greenhouse effect is an established physical phenomena. The reradiative effects of various anthropogenic gases are scientifically demonstrable, and the increasing concentration of such gases in the atmosphere is irrefutable. The delinquent information is the magnitude of the agravated greenhouse effect (AGE)-induced climatic change, the temporal pace of the change and its spatial distribution. The pace of the climatic change implied by many of the general circulation model (GCM) estimates is for a northern hemispheric warming 10-50 times faster than the change since the last ice age. At a relatively aggregated representation, researching the impact of climate change involves estimating energy use and greenhouse gas atmospheric retention, climate modeling and socio-economic impact models. Recognizing that certain of the impacts of anthropogenic gasses will prove to be cumulative, non-reversible and synergistic, it would be prudent to examine mitigating options for immediate implementation. Given the current degree of scientific uncertainty, response priorities would be on the no-regrets or covering-the-bets options. 14 refs., 1 fig., 1 tab

    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

    Sweden's national communication to the UN Convention on Climate Change describes everything about the emission and absorption of greenhouse gases, the motives and forces behind emissions, and official Swedish climate policies. Every five years, Sweden submits a communication on practical climate efforts in Sweden to the UN Convention on Climate Change. The Swedish Environmental Protection Board has coordinated the work of producing the basic documentation for the communication, which also describes the measures already taken and those planned for the future. In addition, scenarios have been adopted for developments in Swedish greenhouse gas emissions, Sweden's vulnerability and Swedish research into the climate and climate change

    Recognizing that climate change will affect agricultural systems both through mean changes and through shifts in climate variability and associated extreme events, we present preliminary analyses of climate impacts from a network of 1137 crop modeling sites contributed to the AgMIP Coordinated Climate-Crop Modeling Project (C3MP). At each site sensitivity tests were run according to a common protocol, which enables the fitting of crop model emulators across a range of carbon dioxide, temperature, and water (CTW) changes. C3MP can elucidate several aspects of these changes and quantify crop responses across a wide diversity of farming systems. Here we test the hypothesis that climate change and variability interact in three main ways. First, mean climate changes can affect yields across an entire time period. Second, extreme events (when they do occur) may be more sensitive to climate changes than a year with normal climate. Third, mean climate changes can alter the likelihood of climate extremes, leading to more frequent seasons with anomalies outside of the expected conditions for which management was designed. In this way, shifts in climate variability can result in an increase or reduction of mean yield, as extreme climate events tend to have lower yield than years with normal climate.C3MP maize simulations across 126 farms reveal a clear indication and quantification (as response functions) of mean climate impacts on mean yield and clearly show that mean climate changes will directly affect the variability of yield. Yield reductions from increased climate variability are not as clear as crop models tend to be less sensitive to dangers on the cool and wet extremes of climate variability, likely underestimating losses from water-logging, floods, and frosts.

  5. On climate change and economic growth

    2005-01-01

    The economic impact of climate change is usually measured as the extent to which the climate of a given period affects social welfare in that period. This static approach ignores the dynamic effects through which climate change may affect economic growth and hence future welfare. In this paper we take a closer look at these dynamic effects, in particular saving and capital accumulation. With a constant savings rate, a lower output due to climate change will lead to a proportionate reduction in investment which in turn will depress future production (capital accumulation effect) and, in almost all cases, future consumption per capita. If the savings rate is endogenous, forward looking agents would change their savings behavior to accommodate the impact of future climate change. This suppresses growth prospects in absolute and per capita terms (savings effect). In an endogenous growth context, these two effects may be exacerbated through changes in labour productivity and the rate of technical progress. Simulations using a simple climate-economy model suggest that the capital accumulation effect is important, especially if technological change is endogenous, and may be larger than the direct impact of climate change. The savings effect is less pronounced. The dynamic effects are more important, relative to the direct effects, if climate change impacts are moderate overall. This suggests that they are more of a concern in developed countries, which are believed to be less vulnerable to climate change. The magnitude of dynamic effects is not sensitive to the choice of discount rate

  6. Climate change hotspots in the CMIP5 global climate model ensemble.

    2012-01-10

    We use a statistical metric of multi-dimensional climate change to quantify the emergence of global climate change hotspots in the CMIP5 climate model ensemble. Our hotspot metric extends previous work through the inclusion of extreme seasonal temperature and precipitation, which exert critical influence on climate change impacts. The results identify areas of the Amazon, the Sahel and tropical West Africa, Indonesia, and the Tibetan Plateau as persistent regional climate change hotspots throughout the 21 st century of the RCP8.5 and RCP4.5 forcing pathways. In addition, areas of southern Africa, the Mediterranean, the Arctic, and Central America/western North America also emerge as prominent regional climate change hotspots in response to intermediate and high levels of forcing. Comparisons of different periods of the two forcing pathways suggest that the pattern of aggregate change is fairly robust to the level of global warming below approximately 2°C of global warming (relative to the late-20 th -century baseline), but not at the higher levels of global warming that occur in the late-21 st -century period of the RCP8.5 pathway, with areas of southern Africa, the Mediterranean, and the Arctic exhibiting particular intensification of relative aggregate climate change in response to high levels of forcing. Although specific impacts will clearly be shaped by the interaction of climate change with human and biological vulnerabilities, our identification of climate change hotspots can help to inform mitigation and adaptation decisions by quantifying the rate, magnitude and causes of the aggregate climate response in different parts of the world.

    Although not considered in climate models, perceived risk stemming from extreme climate events may induce behavioural changes that alter greenhouse gas emissions. Here, we link the C-ROADS climate model to a social model of behavioural change to examine how interactions between perceived risk and emissions behaviour influence projected climate change. Our coupled climate and social model resulted in a global temperature change ranging from 3.4-6.2 °C by 2100 compared with 4.9 °C for the C-ROADS model alone, and led to behavioural uncertainty that was of a similar magnitude to physical uncertainty (2.8 °C versus 3.5 °C). Model components with the largest influence on temperature were the functional form of response to extreme events, interaction of perceived behavioural control with perceived social norms, and behaviours leading to sustained emissions reductions. Our results suggest that policies emphasizing the appropriate attribution of extreme events to climate change and infrastructural mitigation may reduce climate change the most.

    Traditional climate classification or regionalization characterizes the mean state of climate condition, which cannot meet the demand of addressing climate change currently. We have developed a climate change classification method, as well as the fundamental principles, an indicator system, and mapping techniques of climate change regionalization. This study used annual mean temperature and total precipitation as climatic indices, and linear trend and variation change as change indices to characterize climate change quantitatively. The study has proposed a scheme for world climate change regionalization based on a half century of climate data(1961–2010). Level-I regionalization divides the world into 12 tendency zones based on the linear trend of climate, level-II regionalization resulted in 28 fluctuation regions based on the variation change of climate. Climate change regionalization provides a scientific basis for countries and regions to develop plans for adapting to climate change, especially for managing climate-related disaster or environmental risks.

  9. Natural versus anthropogenic climate change: Swedish farmers' joint construction of climate perceptions.

    While previous research into understandings of climate change has usually examined general public perceptions, this study offers an audience-specific departure point. This article analyses how Swedish farmers perceive climate change and how they jointly shape their understandings. The agricultural sector is of special interest because it both contributes to and is directly affected by climate change. Through focus group discussions with Swedish farmers, this study finds that (1) farmers relate to and understand climate change through their own experiences, (2) climate change is understood either as a natural process subject to little or no human influence or as anthropogenic and (3) various communication tools contribute to the formation of natural and anthropogenic climate change frames. The article ends by discussing frame resonance and frame clash in public understanding of climate change and by comparing potential similarities and differences in how various segments of the public make sense of climate change. © The Author(s) 2014.

    The amplification of climatic warming in the Arctic and the sensitivity of physical, biological, and human systems to changes in climate make the Arctic particularly vulnerable to climate changes. Large areas of the Arctic permafrost and sea ice are expected to disappear under climate warming and these changes will have considerable impacts on the natural and built environment of the north. A review is presented of some recent studies on what these impacts could be for the permafrost and sea ice environment and to identify linkages with socioeconomic activities. Terrestrial adaptation to climate change will include increases in ground temperature; melting of permafrost with consequences such as frost heave, mudslides, and substantial settlement; rotting of peat contained in permafrost areas, with subsequent emission of CO 2 ; increased risk of forest fire; and flooding of low-lying areas. With regard to the manmade environment, structures that will be affected include buildings, pipelines, highways, airports, mines, and railways. In marine areas, climate change will increase the ice-free period for marine transport operations and thus provide some benefit to the offshore petroleum industry. This benefit will be offset by increased wave height and period, and increased coastal erosion. The offshore industry needs to be particularly concerned with these impacts since the expected design life of industry facilities (30-60 y) is of the same order as the time frame for possible climatic changes. 18 refs., 5 figs

    Over the past two decades, concern about human-induced climate change has become an increasingly important item on the environmental and political agenda. The signing of the United Nations Framework Convention on Climate Change and the adoption of Agenda 21 at the United Nations Conference on Environment and Development in Rio de Janeiro in 1992 provided international organizations and the nations of the world with a new focus for climate-related activities. Although there remains considerable scientific uncertainty about the extent, magnitude, and rate of climate change and the impacts of such change, actions to address climate change have been initiated both internationally and nationally.

    Climate change, and more specifically the carbon emissions from energy production and use, is one of the more vexing problems facing society today. The Intergovernmental Panel on Climate Change (IPCC) has just completed its latest assessment on the state of the science of climate change, on the potential consequences related to this change, and on the mitigation steps that could be implemented beginning now, particularly in the energy sector. Few people now doubt that anthropogenic climate change is real or that steps must be taken to deal with it. The World Energy Council has long recognized this serious concern and that in its role as the world's leading international energy organization, it can address the concerns of how to provide adequate energy for human well-being while sustaining our overall quality of life. It has now performed and published 15 reports and working papers on this subject. This report examines what has worked and what is likely to work in the future in this regard and provides policymakers with a practical roadmap to a low-carbon future and the steps needed to achieve it.

    Climate change is already affecting the Bering Sea and Aleutian Island region of Alaska. Past and present marine research across a broad spectrum of disciplines is shedding light on what sectors of the ecosystem and the human dimension will be most impacted. In a grassroots approach to extend existing research efforts, leveraging recently completed downscaled climate projections for the Bering Sea and Aleutian Islands region, we convened a team of 30 researchers-- with expertise ranging from anthropology to zooplankton to marine mammals-- to assess climate projections in the context of their expertise. This Aleutian-Bering Climate Vulnerability Assessment (ABCVA) began with researchers working in five teams to evaluate the vulnerabilities of key species and ecosystem services relative to projected changes in climate. Each team identified initial vulnerabilities for their focal species or services, and made recommendations for further research and information needs that would help managers and communities better understand the implications of the changing climate in this region. Those draft recommendations were shared during two focused, public sessions held within two hub communities for the Bering and Aleutian region: Unalaska and St. Paul. Qualitative insights about local concerns and observations relative to climate change were collected during these sessions, to be compared to the recommendations being made by the ABCVA team of researchers. Finally, we used a Structured Decision Making process to prioritize the recommendations of participating scientists, and integrate the insights shared during our community sessions. This work brought together residents, stakeholders, scientists, and natural resource managers to collaboratively identify priorities for addressing current and expected future impacts of climate change. Recommendations from this project will be incorporated into future research efforts of the Aleutian and Bering Sea Islands Landscape Conservation

    Knowledge of factors that trigger human response to climate change is crucial for effective climate change policy communication. Climate change has been claimed to have low salience as a risk issue because it cannot be directly experienced. Still, personal factors such as strength of belief in local effects of climate change have been shown to correlate strongly with responses to climate change and there is a growing literature on the hypothesis that personal experience of climate change (and/or its effects) explains responses to climate change. Here we provide, using survey data from 845 private forest owners operating in a wide range of bio-climatic as well as economic-social-political structures in a latitudinal gradient across Europe, the first evidence that the personal strength of belief and perception of local effects of climate change, highly significantly explain human responses to climate change. A logistic regression model was fitted to the two variables, estimating expected probabilities ranging from 0.07 (SD ± 0.01) to 0.81 (SD ± 0.03) for self-reported adaptive measures taken. Adding socio-demographic variables improved the fit, estimating expected probabilities ranging from 0.022 (SD ± 0.008) to 0.91 (SD ± 0.02). We conclude that to explain and predict adaptation to climate change, the combination of personal experience and belief must be considered.

    Global climate change impacts on human and natural systems are predicted to be severe, far reaching, and to affect the most physically and economically vulnerable disproportionately. Society can respond to these threats through two strategies: mitigation and adaptation. Industry, commerce, and government play indispensable roles in these actions but so do individuals, if they are receptive to behavior change. We explored whether the health frame can be used as a context to motivate behavioral reductions of greenhouse gas emissions and adaptation measures. In 2008, we conducted a cross-sectional survey in the United States using random digit dialing. Personal relevance of climate change from health threats was explored with the Health Belief Model (HBM) as a conceptual frame and analyzed through logistic regressions and path analysis. Of 771 individuals surveyed, 81% (n = 622) acknowledged that climate change was occurring, and were aware of the associated ecologic and human health risks. Respondents reported reduced energy consumption if they believed climate change could affect their way of life (perceived susceptibility), Odds Ratio (OR) = 2.4 (95% Confidence Interval (CI): 1.4-4.0), endanger their life (perceived severity), OR = 1.9 (95% CI: 1.1-3.1), or saw serious barriers to protecting themselves from climate change, OR = 2.1 (95% CI: 1.2-3.5). Perceived susceptibility had the strongest effect on reduced energy consumption, either directly or indirectly via perceived severity. Those that reported having the necessary information to prepare for climate change impacts were more likely to have an emergency kit OR = 2.1 (95% CI: 1.4-3.1) or plan, OR = 2.2 (95% CI: 1.5-3.2) for their household, but also saw serious barriers to protecting themselves from climate change or climate variability, either by having an emergency kit OR = 1.6 (95% CI: 1.1-2.4) or an emergency plan OR = 1.5 (95%CI: 1.0-2.2). Motivation for voluntary mitigation is mostly dependent on

    A summary is presented of a collection of papers on the economic methodologies applicable to studies of the impact of global climate variability and change. The research was sponsored by the Canadian Climate program and was conducted as part of a project investigating the potential impacts on various sectors of the Canadian economy of climate warming due to the greenhouse effect. Topics of the papers include microeconomic analysis, benefit/cost analysis, input-output analysis, policy options regarding water levels in the Great Lakes, the scenario approach to assessing socio-economic sensitivities to climate change in the agri-food sector, and analysis of weather impacts. Several analytical tools are seen to be readily applicable to economic analyses of the effects of climate change, and issues of future water supply and demand are seen as central to climate impact assessment, and of particular concern to Canada

    Climate change, its mitigation, and adaption to its impacts are among the greatest challenges of our times. Despite the importance of societal decisions in determining climate change outcomes, flawed mental models about climate change remain widespread, are often deeply entrenched, and present significant barriers to understanding and decision-making around climate change. Here, we describe two simulation role-playing games that combine active, affective, and analytical learning to enable shifts of deeply held conceptions about climate change. The games, World Climate and Future Climate, use a state-of-the-art decision support simulation, C-ROADS (Climate Rapid Overview and Decision Support) to provide users with immediate feedback on the outcomes of their mitigation strategies at the national level, including global greenhouse gas (GHG) emissions and concentrations, mean temperature changes, sea level rise, and ocean acidification. C-ROADS outcomes are consistent with the atmosphere-ocean general circulation models (AOGCMS), such as those used by the IPCC, but runs in less than one second on ordinary laptops, providing immediate feedback to participants on the consequences of their proposed policies. Both World Climate and Future Climate role-playing games provide immersive, situated learning experiences that motivate active engagement with climate science and policy. In World Climate, participants play the role of United Nations climate treaty negotiators. Participant emissions reductions proposals are continually assessed through interactive exploration of the best available science through C-ROADS. Future Climate focuses on time delays in the climate and energy systems. Participants play the roles of three generations: today's policymakers, today's youth, and 'just born.' The game unfolds in three rounds 25 simulated years apart. In the first round, only today's policymakers make decisions; In the next round, the young become the policymakers and inherit the

    At the request of Congress, the National Academy of Sciences convened a series of coordinated activities to provide advice on actions and strategies that the nation can take to respond to climate change. As part of this suite of activities, this study examines information needs and recommends ways the federal government can better inform responses by enhancing climate change and greenhouse gas information and reporting systems and by improving climate communication and education. Demand for better information to support climate-related decisions has grown rapidly as people, organizations, and governments have moved ahead with plans and actions to reduce greenhouse gas emissions and to adapt to the impacts of climate change. To meet this demand, good information systems and services are needed. Without such systems, decision makers cannot evaluate whether particular policies and actions are achieving their goals or should be modified. Although the many non-federal efforts to reduce emissions and/or adapt to future climate changes carry considerable potential to reduce risks related to climate change, there is currently no comprehensive way to assess the effectiveness of those efforts. In addition, the diverse climate change responses to date have resulted in a patchwork of regional, state, and local policies that has prompted many state and business leaders to call for the development of a more predictable and coherent policy environment at the federal level. This report demonstrates that the nation lacks comprehensive, robust, and credible information and reporting systems to inform climate choices and evaluate their effectiveness. This report also argues that decision makers can benefit from a systematic and iterative framework for responding to climate change, in which decisions and policies can be revised in light of new information and experience and that improved information and reporting systems allow for ongoing evaluation of responses to climate risks.

    Decades of study on climatic change and its direct and indirect effects on forest ecosystems provide important insights for forest science, management, and policy. A synthesis of recent research from the northeastern United States and eastern Canada shows that the climate of the region has become warmer and wetter over the past 100 years and that there are more extreme precipitation events. Greater change is projected in the future. The amount of projected future change depends on the emissions scenarios used. Tree species composition of northeast forests has shifted slowly in response to climate for thousands of years. However, current human-accelerated climate change is much more rapid and it is unclear how forests will respond to large changes in suitable habitat. Projections indicate significant declines in suitable habitat for spruce-fir forests and expansion of suitable habitat for oak-dominated forests. Productivity gains that might result from extended growing seasons and carbon dioxide and nitrogen fertilization may be offset by productivity losses associated with the disruption of species assemblages and concurrent stresses associated with potential increases in atmospheric deposition of pollutants, forest fragmentation, and nuisance species. Investigations of links to water and nutrient cycling suggest that changes in evapotranspiration, soil respiration, and mineralization rates could result in significant alterations of key ecosystem processes. Climate change affects the distribution and abundance of many wildlife species in the region through changes in habitat, food availability, thermal tolerances, species interactions such as competition, and susceptibility to parasites and disease. Birds are the most studied northeastern taxa. Twenty-seven of the 38 bird species for which we have adequate long-term records have expanded their ranges predominantly in a northward direction. There is some evidence to suggest that novel species, including pests and

    Rising global temperature is causing major physical, chemical, and ecological changes across the planet. There is wide consensus among scientific organizations and climatologists that these broad effects, known as climate change, are the result of contemporary human activity. Climate change poses threats to human health, safety, and security. Children are uniquely vulnerable to these threats. The effects of climate change on child health include physical and psychological sequelae of weather disasters, increased heat stress, decreased air quality, altered disease patterns of some climate-sensitive infections, and food, water, and nutrient insecurity in vulnerable regions. Prompt implementation of mitigation and adaptation strategies will protect children against worsening of the problem and its associated health effects. This technical report reviews the nature of climate change and its associated child health effects and supports the recommendations in the accompanying policy statement on climate change and children's health.

  1. Climate of origin affects tick (Ixodes ricinus) host-seeking behavior in response to temperature: implications for resilience to climate change?

    2014-04-01

    Climate warming is changing distributions and phenologies of many organisms and may also impact on vectors of disease-causing pathogens. In Europe, the tick Ixodes ricinus is the primary vector of medically important pathogens (e.g., Borrelia burgdorferi sensu lato, the causative agent of Lyme borreliosis). How might climate change affect I. ricinus host-seeking behavior (questing)? We hypothesize that, in order to maximize survival, I. ricinus have adapted their questing in response to temperature in accordance with local climates. We predicted that ticks from cooler climates quest at cooler temperatures than those from warmer climates. This would suggest that I. ricinus can adapt and therefore have the potential to be resilient to climate change. I. ricinus were collected from a cline of climates using a latitudinal gradient (northeast Scotland, North Wales, South England, and central France). Under laboratory conditions, ticks were subjected to temperature increases of 1°C per day, from 6 to 15°C. The proportion of ticks questing was recorded five times per temperature (i.e., per day). The theoretical potential to quest was then estimated for each population over the year for future climate change projections. As predicted, more ticks from cooler climates quested at lower temperatures than did ticks from warmer climates. The proportion of ticks questing was strongly associated with key climate parameters from each location. Our projections, based on temperature alone, suggested that populations could advance their activity season by a month under climate change, which has implications for exposure periods of hosts to tick-borne pathogens. Our findings suggest that I. ricinus have adapted their behavior in response to climate, implying some potential to adapt to climate change. Predictive models of I. ricinus dynamics and disease risk over continental scales would benefit from knowledge of these differences between populations.

    Identifying the climatic drivers of an ecological system is a key step in assessing its vulnerability to climate change. The climatic dimensions to which a species or system is most sensitive - such as means or extremes - can guide methodological decisions for projections of ecological impacts and vulnerabilities. However, scientific workflows for combining climate projections with ecological models have received little explicit attention. We review Global Climate Model (GCM) performance along different dimensions of change and compare frameworks for integrating GCM output into ecological models. In systems sensitive to climatological means, it is straightforward to base ecological impact assessments on mean projected changes from several GCMs. Ecological systems sensitive to climatic extremes may benefit from what we term the 'model space' approach: a comparison of ecological projections based on simulated climate from historical and future time periods. This approach leverages the experimental framework used in climate modeling, in which historical climate simulations serve as controls for future projections. Moreover, it can capture projected changes in the intensity and frequency of climatic extremes, rather than assuming that future means will determine future extremes. Given the recent emphasis on the ecological impacts of climatic extremes, the strategies we describe will be applicable across species and systems. We also highlight practical considerations for the selection of climate models and data products, emphasizing that the spatial resolution of the climate change signal is generally coarser than the grid cell size of downscaled climate model output. Our review illustrates how an understanding of how climate model outputs are derived and downscaled can improve the selection and application of climatic data used in ecological modeling. © 2017 John Wiley & Sons Ltd.

  4. Climate change projections: past and future mysteries of climate science

    Full text: Full text: The history of climate change has been wrapped in mysteries. Some have been solved, and we await the outcome of others. The major mystery of 20th century climate was why did temperatures rise in the early part of the century, level off, and then rise rapidly again after the 1970s? It has only been in the past seven years that advances in climate modelling have allowed us to deconstruct 20th century climate to pull apart the separate influences of natural and human-caused factors. This has allowed us to understand the subtle interplay between these various influences that produced the temperature time evolution. Another mystery has involved extreme weather and climate events. Again, climate models have allowed us to quantify how the small changes in average climate translate into much larger changes of regional extremes. The biggest remaining mysteries in climate science involve the future, and how the climate will evolve over the coming century. Up until now, various scenarios postulating different possible outcomes for 21st century climate, assuming different types of human activities, have been run in the climate models to provide a wide range of possible futures. However, more recently the outlook for global warming is being framed as a combination of mitigation and adaptation. If policy actions are taken to mitigate part of the problem of global warming, then climate models must be relied on to quantify the time-evolving picture of how much regional climate change we must adapt to. Solving this mystery will be the biggest and most important challenge ever taken on by the climate modelling community

    The author proposes a review of four publications about climate change published in 2012 and 2013. He more particularly focuses on how these publications express how climate change is perceived by the different components of our modern societies, how these perceptions have an influence on the answer to challenges related to this phenomenon, what global warming tells us about mankind ability to (re)act to this major challenge. He notices that any doubt about the reality of climate change is exploited and maintains some confusion, favours the propagation and persistence of popular misbelief such as: population of developing countries will be more impacted by effects of climate change, only rich people can afford interest in environment protection and climate preservation. He outlines that a doubting community will not act, and notices that technological advances, for example geo-engineering or climate engineering, tend to deliberately manipulate the environment to counteract the climate change due to human activity

    Increasing connectivity is an important strategy for facilitating species range shifts and maintaining biodiversity in the face of climate change. To date, however, few researchers have included future climate projections in efforts to prioritize areas for increasing connectivity. We identified key areas likely to facilitate climate-induced species' movement across western North America. Using historical climate data sets and future climate projections, we mapped potential species' movement routes that link current climate conditions to analogous climate conditions in the future (i.e., future climate analogs) with a novel moving-window analysis based on electrical circuit theory. In addition to tracing shifting climates, the approach accounted for landscape permeability and empirically derived species' dispersal capabilities. We compared connectivity maps generated with our climate-change-informed approach with maps of connectivity based solely on the degree of human modification of the landscape. Including future climate projections in connectivity models substantially shifted and constrained priority areas for movement to a smaller proportion of the landscape than when climate projections were not considered. Potential movement, measured as current flow, decreased in all ecoregions when climate projections were included, particularly when dispersal was limited, which made climate analogs inaccessible. Many areas emerged as important for connectivity only when climate change was modeled in 2 time steps rather than in a single time step. Our results illustrate that movement routes needed to track changing climatic conditions may differ from those that connect present-day landscapes. Incorporating future climate projections into connectivity modeling is an important step toward facilitating successful species movement and population persistence in a changing climate. © 2017 Society for Conservation Biology.

    This white paper represents a summary of work intended to lay the foundation for development of a climatological/agent model of climate-induced conflict. The paper combines several loosely-coupled efforts and is the final report for a four-month late-start Laboratory Directed Research and Development (LDRD) project funded by the Advanced Concepts Group (ACG). The project involved contributions by many participants having diverse areas of expertise, with the common goal of learning how to tie together the physical and human causes and consequences of climate change. We performed a review of relevant literature on conflict arising from environmental scarcity. Rather than simply reviewing the previous work, we actively collected data from the referenced sources, reproduced some of the work, and explored alternative models. We used the unfolding crisis in Darfur (western Sudan) as a case study of conflict related to or triggered by climate change, and as an exercise for developing a preliminary concept map. We also outlined a plan for implementing agents in a climate model and defined a logical progression toward the ultimate goal of running both types of models simultaneously in a two-way feedback mode, where the behavior of agents influences the climate and climate change affects the agents. Finally, we offer some ''lessons learned'' in attempting to keep a diverse and geographically dispersed group working together by using Web-based collaborative tools.

    Climate, physical landscapes, and biota interact to generate heterogeneous hydrologic conditions in space and over time, which are reflected in spatial patterns of species distributions. As these species distributions respond to rapid climate change, microrefugia may support local species persistence in the face of deteriorating climatic suitability. Recent focus on temperature as a determinant of microrefugia insufficiently accounts for the importance of hydrologic processes and changing water availability with changing climate. Where water scarcity is a major limitation now or under future climates, hydrologic microrefugia are likely to prove essential for species persistence, particularly for sessile species and plants. Zones of high relative water availability - mesic microenvironments - are generated by a wide array of hydrologic processes, and may be loosely coupled to climatic processes and therefore buffered from climate change. Here, we review the mechanisms that generate mesic microenvironments and their likely robustness in the face of climate change. We argue that mesic microenvironments will act as species-specific refugia only if the nature and space/time variability in water availability are compatible with the ecological requirements of a target species. We illustrate this argument with case studies drawn from California oak woodland ecosystems. We posit that identification of hydrologic refugia could form a cornerstone of climate-cognizant conservation strategies, but that this would require improved understanding of climate change effects on key hydrologic processes, including frequently cryptic processes such as groundwater flow. © 2017 John Wiley & Sons Ltd.

    Communicating climate change to people from diverse sectors of society has proven to be difficult in the United States. It is widely recognized that difficulties arise from a number of sources, including: basic science understanding, the psychologically affect laden content surrounding climate change, and the diversity of value systems that exist in our society. I explore ways of working with the affect that arises around climate change and describe specific methods to work with the resistance often encountered when communicating this important issue. The techniques I describe are rooted in psychology and group process and provide means for creating more effective narratives to break through the barriers to communicating climate change science. Examples are given from personal experiences in presenting climate change to diverse groups.

    The talk addresses the scientific consensus concerning climate change, and outlines the many paths that are open to mitigate climate change and its effects on human activities. Diverse aspects of the changing water cycle on Earth are used to illustrate the reality climate change. These include melting snowpack, glaciers, and sea ice; changes in runoff; rising sea level; moving ecosystems, an more. Human forcing of climate change is then explained, including: greenhouse gasses, atmospheric aerosols, and changes in land use. Natural forcing effects are briefly discussed, including volcanoes and changes in the solar cycle. Returning to Earth's water cycle, the effects of climate-induced changes in water resources is presented. Examples include wildfires, floods and droughts, changes in the production and availability of food, and human social reactions to these effects. The lk then passes to a discussion of common human reactions to these forecasts of climate change effects, with a summary of recent research on the subject, plus several recent historical examples of large-scale changes in human behavior that affect the climate and ecosystems. Finally, in the face for needed action on climate, the many options for mitigation of climate change and adaptation to its effects are presented, with examples of the ability to take affordable, and profitable action at most all levels, from the local, through national.

    The ocean influences climate by storing and transporting large amounts of heat, freshwater, and carbon, and exchanging these properties with the atmosphere. About 93% of the excess heat energy stored by the earth over the last 50 years is found in the ocean. More than three quarters of the total exchange of water between the atmosphere and the earth's surface through evaporation and precipitation takes place over the oceans. The ocean contains 50 times more carbon than the atmosphere and is at present acting to slow the rate of climate change by absorbing one quarter of human emissions of carbon dioxide from fossil fuel burning, cement production, deforestation and other land use change.Here I summarize the observational evidence of change in the ocean, with an emphasis on basin- and global-scale changes relevant to climate. These include: changes in subsurface ocean temperature and heat content, evidence for regional changes in ocean salinity and their link to changes in evaporation and precipitation over the oceans, evidence of variability and change of ocean current patterns relevant to climate, observations of sea level change and predictions over the next century, and biogeochemical changes in the ocean, including ocean acidification.

    Dynamic interactions between and within the biogeophysical and human environments lead to the production, processing, distribution, preparation and consumption of food, resulting in food systems that underpin food security. Food systems encompass food availability (production, distribution and exchange), food access (affordability, allocation and preference) and food utilization (nutritional and societal values and safety), so that food security is, therefore, diminished when food systems are stressed. Such stresses may be induced by a range of factors in addition to climate change and/or other agents of environmental change (e.g. conflict, HIV/AIDS) and may be particularly severe when these factors act in combination. Urbanization and globalization are causing rapid changes to food systems. Climate change may affect food systems in several ways ranging from direct effects on crop production (e.g. changes in rainfall leading to drought or flooding, or warmer or cooler temperatures leading to changes in the length of growing season), to changes in markets, food prices and supply chain infrastructure. The relative importance of climate change for food security differs between regions. For example, in southern Africa, climate is among the most frequently cited drivers of food insecurity because it acts both as an underlying, ongoing issue and as a short-lived shock. The low ability to cope with shocks and to mitigate long-term stresses means that coping strategies that might be available in other regions are unavailable or inappropriate. In other regions, though, such as parts of the Indo-Gangetic Plain of India, other drivers, such as labour issues and the availability and quality of ground water for irrigation, rank higher than the direct effects of climate change as factors influencing food security. Because of the multiple socio-economic and bio-physical factors affecting food systems and hence food security, the capacity to adapt food systems to reduce their

    Wildfires have played a determining role in distribution, composition and structure of many ecosystems worldwide and climatic changes are widely considered to be a major driver of future fire regime changes. However, forecasting future climatic change induced impacts on fire regimes will require a clearer understanding of other drivers of abrupt fire regime changes. Here, we focus on evidence from different environmental and temporal settings of fire regimes changes that are not directly attributed to climatic changes. We review key cases of these abrupt fire regime changes at different spatial and temporal scales, including those directly driven (i) by fauna, (ii) by invasive plant species, and (iii) by socio-economic and policy changes. All these drivers might generate non-linear effects of landscape changes in fuel structure; that is, they generate fuel changes that can cross thresholds of landscape continuity, and thus drastically change fire activity. Although climatic changes might contribute to some of these changes, there are also many instances that are not primarily linked to climatic shifts. Understanding the mechanism driving fire regime changes should contribute to our ability to better assess future fire regimes.

    Long-term changes in the level of solar activity are found in historical records and in fossil radiocarbon in tree-rings. Typical of these changes are the Maunder Minimum (A.D. 1645-1715), the Spoerer Minimum (A.D. 1400-1510), and a Medieval Maximum (c. A.D. 1120-1280). Eighteen such features are identified in the tree-ring radiocarbon record of the past 7500 years and compared with a record of world climate. In every case when long-term solar activity falls, mid-latitude glaciers advance and climate colls; at times of high solar activity glaciers recede and climate warms. It is proposed that changes in the level of solar activity and in climate may have a common cause: slow changes in the solar constant, of about 1% amplitude. (Auth.)

    This research project studies the evolution and determinants of corporate climate strategies of multinationals. Since most companies are affected by global climate change in a direct or indirect way, a range of strategies are emerging to mitigate climate change. These strategies are not only of a political nature (e.g. influencing government institutions), but also of a competitive nature. The aim is to introduce a typology of corporate climate strategies, paying specific attention to the market components related to climate change. More and more, multinationals' actions in reducing greenhouse gas emissions are aimed at achieving a sustained competitive advantage in addition to compliance with government regulation. What factors determine these market strategies for climate change will be explored in a theoretical framework based on institutional theory and the resource-based view of the firm.

    As the world's largest distributed store of fresh water, ground water plays a central part in sustaining ecosystems and enabling human adaptation to climate variability and change. The strategic importance of ground water for global water and food security will probably intensify under climate change as more frequent and intense climate extremes (droughts and floods) increase variability in precipitation, soil moisture and surface water. Here we critically review recent research assessing the impacts of climate on ground water through natural and human-induced processes as well as through groundwater-driven feedbacks on the climate system. Furthermore, we examine the possible opportunities and challenges of using and sustaining groundwater resources in climate adaptation strategies, and highlight the lack of groundwater observations, which, at present, limits our understanding of the dynamic relationship between ground water and climate.

    In order to address the key question if a targeted approach to climate change response is feasible, different aspects of this question are analyzed. First, the scientific and political aspects of different options to determine specific long-term objectives for climate change are evaluated on the basis of the current scientific insights and the experiences over the last 5 years to develop climate objectives. Preliminary directions for such objectives are given. Next, important analytical tools are discussed that can be applied to analyze the different options and their implications in detail. In order to evaluate the implications of mitigation options, strategies that are consistent with the preliminary climate goals are analyzed in the third part. In chapter 2, the concept of long-term environmental goals, derived from critical levels of climate change, is discussed. Also a historical perspective is provided. A new, systematic regionalized and risk-based approach to elaborate the ultimate objective of the Framework Convention on Climate Change is proposed. In chapter 3 scenarios and integrated models are discussed. Central is the description of scenarios that were developed with RlVM's Integrated Model to Assess the Greenhouse Effect (IMAGE) and the US-EPA's Atmospheric Stabilization Framework (ASF). In chapter 4 potential long-term international emissions control strategies for the different sources and sinks of the most important greenhouse gases are analyzed. Carbon dioxide from energy, carbon dioxide from deforestation, and non-CO 2 greenhouse gases are dealt with subsequently. The dissertation ends with general conclusions and recommendations for the further design of a targeted approach to climate change response, the development of analytical tools to support policy development in the area of climate change, and strategies that are consistent with preliminary long-term environmental goals. 66 figs., 8 tabs., 417 refs., 1 appendix

    The sustainability of ecosystem services depends on a firm understanding of both how organisms provide these services to humans and how these organisms will be altered with a changing climate. Unquestionably a dominant feature of most ecosystems, invertebrates affect many ecosystem services and are also highly responsive to climate change. However, there is still a basic lack of understanding of the direct and indirect paths by which invertebrates influence ecosystem services, as well as how climate change will affect those ecosystem services by altering invertebrate populations. This indicates a lack of communication and collaboration among scientists researching ecosystem services and climate change effects on invertebrates, and land managers and researchers from other disciplines, which becomes obvious when systematically reviewing the literature relevant to invertebrates, ecosystem services, and climate change. To address this issue, we review how invertebrates respond to climate change. We then review how invertebrates both positively and negatively influence ecosystem services. Lastly, we provide some critical future directions for research needs, and suggest ways in which managers, scientists and other researchers may collaborate to tackle the complex issue of sustaining invertebrate-mediated services under a changing climate. © 2012 The Authors.

    2003-01-01

    The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on fisheries focuses on the impact of climate change on Canada's marine and freshwater fisheries, and the role of adaptation in reducing the vulnerability of the sector. Canadian fisheries encompass the Atlantic, Pacific and Arctic oceans as well as freshwater systems. Fish health, productivity and distribution is strongly influenced by climatic factors such as air and water temperature, precipitation and wind. Most fish species have a distinct set of environmental conditions for optimal growth and survival. If the conditions change in response to changing climate, the fish may be affected. Some of the impacts include reduced growth, increased competition, a shift in species distribution, greater susceptibility to disease, and altered ecosystem function. Studies show that in some areas, fisheries may already be experiencing the effect of climate change. Recommendations were suggested on how to deal with the impacts associated with climate change in sensitive environments. It was noted that actions taken in the fisheries sector will have implications for the water resources, transportation, tourism and human health sectors. 103 refs., 2 tabs., 6 figs

    The course "Atmospheric Research - Climate Change" is offered to master Earth System Science students within the specialisation "Climate and Environment" at the Technical University Bergakademie Freiberg. This module takes a comprehensive approach to climate sciences, reaching from the natural sciences background of climate change via the social components of the issue to the statistical analysis of changes in climate parameters. The course aims at qualifying the students to structure the physical and chemical basics of the climate system including relevant feedbacks. The students can evaluate relevant drivers of climate variability and change on various temporal and spatial scales and can transform knowledge from climate history to the present and the future. Special focus is given to the assessment of uncertainties related to climate observations and projections as well as the specific challenges of extreme weather and climate events. At the end of the course the students are able to critically reflect and evaluate climate change related results of scientific studies and related issues in media. The course is divided into two parts - "Climate Change" and "Climate Data Analysis" and encompasses two lectures, one seminar and one exercise. The weekly "Climate change" lecture transmits the physical and chemical background for climate variation and change. (Pre)historical, observed and projected climate changes and their effects on various sectors are being introduced and discussed regarding their implications for society, economics, ecology and politics. The related seminar presents and discusses the multiple reasons for controversy in climate change issues, based on various texts. Students train the presentation of scientific content and the discussion of climate change aspects. The biweekly lecture on "Climate data analysis" introduces the most relevant statistical tools and methods in climate science. Starting with checking data quality via tools of exploratory

In the course of Earth evolution, climate has changed many times, sometimes dramatically. Warmer eras always replaced and were in turn replaced by glacial ones. However, the climate of the past almost ten thousand years has been very stable. During this period human civilization has also developed. In the past nearly 100 years - since the beginning of industrialization - the global average temperature has increased by approx. 0.6 ° C (after IPCC (Intergovernmental Panel on Climate Change, faster than at any time in the last 1000 years.

    Climate change is a major issue. A survey of the utility companies that account for 80% of the world's electric power was released during the 20. climate conference in Lima as part of the World Energy Council' Global Electricity Initiative. It has concluded that all these utilities see climate change as being real and declare that policies for adapting to it are as important as policies for limiting it. Nonetheless, 97% of these utilities think that consumers will refuse to pay more for decarbonized electricity. This is the core problem in the fight against climate change: all agree that the issue is urgent, some agree about what should be done, but none wants to pay

    The Chinese government has recently pledged to reduce its CO 2 emissions by 2030. Industrial use of energy, however, is just one source of greenhouse gas emissions. Chinese consumers' more affluent lifestyles also lead to increased consumption of energy, which can result in greenhouse gas emissions. Based on a survey of 516 Chinese consumers, the present investigation examined whether their attitudinal motivations and collective efficacy are related to their intentions to engage in personal actions that may help reduce greenhouse gas emissions. Results show that the utilitarian motivation related to the effectiveness of personal actions to alleviate climate change, motivation to express their moral values, self-esteem maintenance motivation, and collective efficacy predicted their attitudes toward these personal actions. Collective efficacy was in turn predicted by future orientation, norms, and the utilitarian motivation. Finally, attitudes and collective efficacy were two major considerations that predicted behavioral intentions. Implications for programs to promote low-carbon actions and lifestyles among Chinese consumers are discussed.

    Full Text Available Abstract Background Global climate change impacts on human and natural systems are predicted to be severe, far reaching, and to affect the most physically and economically vulnerable disproportionately. Society can respond to these threats through two strategies: mitigation and adaptation. Industry, commerce, and government play indispensable roles in these actions but so do individuals, if they are receptive to behavior change. We explored whether the health frame can be used as a context to motivate behavioral reductions of greenhouse gas emissions and adaptation measures. Methods In 2008, we conducted a cross-sectional survey in the United States using random digit dialing. Personal relevance of climate change from health threats was explored with the Health Belief Model (HBM as a conceptual frame and analyzed through logistic regressions and path analysis. Results Of 771 individuals surveyed, 81% (n = 622 acknowledged that climate change was occurring, and were aware of the associated ecologic and human health risks. Respondents reported reduced energy consumption if they believed climate change could affect their way of life (perceived susceptibility, Odds Ratio (OR = 2.4 (95% Confidence Interval (CI: 1.4 - 4.0, endanger their life (perceived severity, OR = 1.9 (95% CI: 1.1 - 3.1, or saw serious barriers to protecting themselves from climate change, OR = 2.1 (95% CI: 1.2 - 3.5.

    Chemically active climate compounds are either primary compounds such as methane (CH4), removed by oxidation in the atmosphere, or secondary compounds such as ozone (O3), sulfate and organic aerosols, formed and removed in the atmosphere. Man-induced climate-chemistry interaction is a two-way process: Emissions of pollutants change the atmospheric composition contributing to climate change through the aforementioned climate components, and climate change, through changes in temperature, dynamics, the hydrological cycle, atmospheric stability, and biosphere-atmosphere interactions, affects the atmospheric composition and oxidation processes in the troposphere. Here we present progress in our understanding of processes of importance for climate-chemistry interactions, and their contributions to changes in atmospheric composition and climate forcing. A key factor is the oxidation potential involving compounds such as O3 and the hydroxyl radical (OH). Reported studies represent both current and future changes. Reported results include new estimates of radiative forcing based on extensive model studies of chemically active climate compounds such as O3, and of particles inducing both direct and indirect effects. Through EU projects such as ACCENT, QUANTIFY, and the AEROCOM project, extensive studies on regional and sector-wise differences in the impact on atmospheric distribution are performed. Studies have shown that land-based emissions have a different effect on climate than ship and aircraft emissions, and different measures are needed to reduce the climate impact. Several areas where climate change can affect the tropospheric oxidation process and the chemical composition are identified. This can take place through enhanced stratospheric-tropospheric exchange of ozone, more frequent periods with stable conditions favouring pollution build up over industrial areas, enhanced temperature-induced biogenic emissions, methane releases from permafrost thawing, and enhanced

    engagement including (1) pessimism—50% of visitors are uncertain whether people will do what is needed to address global warming, and 30% think it is unlikely; (2) low self-efficacy—almost one-half of visitors believe they can personally have little to no impact on addressing climate change; and (3) perceived obstacles—when asked what is standing in their way of doing more to address climate change, over 90% of visitors reported at least one obstacle. The most frequently selected obstacles were lack of knowledge about which actions would be effective and concern about the cost of actions. Nevertheless, zoo visitors are slightly more optimistic about humans' capability to reduce global warming than the general public. Importantly, results also indicate that visitors' concern about climate change and participation in behaviors to address it vary with their sense of connection with animals and nature. Thus, this study offers guidance for the development of educational resources that meet visitors' needs while building on their emotional connections with animals. Our data suggest these resources will be more effective if they support social interactions that reinforce a person's inclination to address climate change, demonstrate the collective impact of individual actions, and aid informed decision-making about effective actions to address climate change.

  20. Conservation and adaptation to climate change.

    2008-12-01

    The need to adapt to climate change has become increasingly apparent, and many believe the practice of biodiversity conservation will need to alter to face this challenge. Conservation organizations are eager to determine how they should adapt their practices to climate change. This involves asking the fundamental question of what adaptation to climate change means. Most studies on climate change and conservation, if they consider adaptation at all, assume it is equivalent to the ability of species to adapt naturally to climate change as stated in Article 2 of the United Nations Framework Convention on Climate Change. Adaptation, however, can refer to an array of activities that range from natural adaptation, at one end of the spectrum, to sustainability science in coupled human and natural systems at the other. Most conservation organizations deal with complex systems in which adaptation to climate change involves making decisions on priorities for biodiversity conservation in the face of dynamic risks and involving the public in these decisions. Discursive methods such as analytic deliberation are useful for integrating scientific knowledge with public perceptions and values, particularly when large uncertainties and risks are involved. The use of scenarios in conservation planning is a useful way to build shared understanding at the science-policy interface. Similarly, boundary organizations-organizations or institutions that bridge different scales or mediate the relationship between science and policy-could prove useful for managing the transdisciplinary nature of adaptation to climate change, providing communication and brokerage services and helping to build adaptive capacity. The fact that some nongovernmental organizations (NGOs) are active across the areas of science, policy, and practice makes them well placed to fulfill this role in integrated assessments of biodiversity conservation and adaptation to climate change.

    From 1990 to the present day, worldwide greenhouse gas emissions have increased by about 25%. Fighting climatic change has become an urgency: we only have 15 years in front of us to inflect the trajectory of worldwide emissions and to avoid a temperature rise of more than 2 deg. C during this century. Therefore, how is it possible to explain the shift between the need of an urgent action and the apparent inertia of some governing parties? How is it possible to implement a worldwide governance capable to answer the urgency of the fight against climatic change? These are the two questions that this pedagogical and concrete book tries to answer by analysing the different dimensions of climatic change and by making a first status of the building up of the international action, and in particular of the Kyoto protocol. For the post-2012 era, research and negotiations are in progress with the objective of reaching an agreement for the Copenhagen conference of December 2009. Several architectures are possible. This book shades light on the advantages and limitations of each of them with the possible compromises. It supplies a pluri-disciplinary approach of the international negotiations, often considered as complex by the general public. Content: 1 - understanding the climatic change stakes: climatic stakes, the main actors behind the figures, the technical-economical stakes; 2 - understanding the present day architecture of the fight against climatic change: strengths and weaknesses of the Kyoto protocol; encouraging research and technology spreading; the other action means in developing countries; 3 - what structure for a future international agreement?: the Bali negotiation process; the ideal vision: an improved Kyoto protocol; the pragmatic vision: individualized commitments; the negotiation space; preventing a planned fiasco.

    Full Text Available Adopting successful climate change mitigation policies requires the public to choose how to balance the sometimes competing goals of managing CO2 emissions and achieving economic growth. It follows that collective action on climate change depends on members of the public to be knowledgeable of the causes and economic ramifications of climate change. The existing literature, however, shows that people often struggle to correctly reason about the fundamental accumulation dynamics that drive climate change. Previous research has focused on using analogy to improve people's reasoning about accumulation, which has been met with some success. However, these existing studies have neglected the role economic factors might play in shaping people's decisions in relation to climate change. Here, we introduce a novel iterated decision task in which people attempt to achieve a specific economic goal by interacting with a causal dynamic system in which human economic activities, CO2 emissions, and warming are all causally interrelated. We show that when the causal links between these factors are highlighted, people's ability to achieve the economic goal of the task is enhanced in a way that approaches optimal responding, and avoids dangerous levels of warming.

    Nominated by Chinese Academy of Sciences as an outstanding Ph.D. thesis. Offers a needed exploration of the temporal and spatial pattern of climate change in southwestern China. Explores the action mechanism among the large-scale atmospheric circulation system, the complicated topography, human activities and regional climate changes. Analyzes the response of glaciers to climate change from the aspects of morphology of the glacier, glacial mass balance and the process of hydrology. This thesis confirms many changes, including sharp temperature rise, interannual variability of precipitation, extreme climate events and significant decreases of sunshine duration and wind speed in southwestern China, and systemically explores the action mechanism between large-scale atmospheric circulation systems, the complicated topography, human activities and regional climate changes. This study also analyzes the response of glaciers to climate change so that on the one hand it clearly reflects the relationship between glacier morphologic changes and climate change; on the other, it reveals the mechanism of action of climate warming as a balance between energy and matter. The achievements of this study reflect a significant contribution to the body of research on the response of climate in cold regions, glaciers and human activities to a global change against the background of the typical monsoon climate, and have provided scientific basis for predictions, countermeasures against disasters from extreme weather, utilization of water and the establishment of counterplans to slow and adapt to climate change.

    Changes in body size and breeding phenology have been identified as two major ecological consequences of climate change, yet it remains unclear whether climate acts directly or indirectly on these variables. To better understand the relationship between climate and ecological changes, it is necessary to determine environmental predictors of both size and phenology using data from prior to the onset of rapid climate warming, and then to examine spatially explicit changes in climate, size, and phenology, not just general spatial and temporal trends. We used 100 years of natural history collection data for the wood frog, Lithobates sylvaticus with a range >9 million km 2 , and spatially explicit environmental data to determine the best predictors of size and phenology prior to rapid climate warming (1901-1960). We then tested how closely size and phenology changes predicted by those environmental variables reflected actual changes from 1961 to 2000. Size, phenology, and climate all changed as expected (smaller, earlier, and warmer, respectively) at broad spatial scales across the entire study range. However, while spatially explicit changes in climate variables accurately predicted changes in phenology, they did not accurately predict size changes during recent climate change (1961-2000), contrary to expectations from numerous recent studies. Our results suggest that changes in climate are directly linked to observed phenological shifts. However, the mechanisms driving observed body size changes are yet to be determined, given the less straightforward relationship between size and climate factors examined in this study. We recommend that caution be used in "space-for-time" studies where measures of a species' traits at lower latitudes or elevations are considered representative of those under future projected climate conditions. Future studies should aim to determine mechanisms driving trends in phenology and body size, as well as the impact of climate on population

    Sea level is a very sensitive index of climate change and variability. Sea level integrates the ocean warming, mountain glaciers and ice sheet melting. Understanding the sea level variability and changes implies an accurate monitoring of the sea level variable at climate scales, in addition to understanding the ocean variability and the exchanges between ocean, land, cryosphere, and atmosphere. That is why Sea Level is one of the Essential Climate Variables (ECV) selected in the frame of the ESA Climate Change Initiative (CCI) program. It aims at providing long-term monitoring of the sea level ECV with regular updates, as required for climate studies. The program is now in its second phase of 3 year (following phase I during 2011-2013). The objectives are firstly to involve the climate research community, to refine their needs and collect their feedbacks on product quality. And secondly to develop, test and select the best algorithms and standards to generate an updated climate time series and to produce and validate the Sea Level ECV product. This will better answer the climate user needs by improving the quality of the Sea Level products and maintain a sustain service for an up-to-date production. This has led to the production of a first version of the Sea Level ECV which has benefited from yearly extensions and now covers the period 1993-2014. Within phase II, new altimeter standards have been developed and tested in order to reprocess the dataset with the best standards for climate studies. The reprocessed ECV will be released in summer 2016. We will present the main achievements of the ESA CCI Sea Level Project. On the one hand, the major steps required to produce the 22 years climate time series are briefly described: collect and refine the user requirements, development of adapted algorithms for climate applications and specification of the production system. On the other hand, the product characteristics are described as well as the results from product

    If Canada intends to meet its greenhouse gas reduction target of 6 per cent below 1990 levels, a fundamental shift in energy use by Canadians is required. The health sector will also be required to change. Global climate change is expected to affect regions differently, some might get wetter, some might get warmer, and others still might get colder. Climate changes will influence a number of health determinants: the geographical range of disease organisms and vectors; temperature extremes and violent weather events; air, food and water quality; the stability of ecosystems. There is a requirement to strongly regulate the emissions of carbon dioxide, methane and other greenhouse gases to limit health risks. Increased air pollution could negatively affect large numbers of people, especially asthma sufferers and people suffering from chronic respiratory ailments and cardiovascular diseases. Changes in precipitation and temperature could increase insect-borne diseases. Water sources could be badly affected by drought, flooding or increased glacial runoff. The thinning of the ozone layer could result in additional skin cancers, impaired vision and other diseases. The document explores the various impacts resulting from climate change. A chapter is devoted to each topic: air pollution, temperature extremes, extreme weather events, vector borne diseases, drought and increased evaporation, food supply and ecosystem range, sea level rise, stratospheric ozone depletion and describes the health impacts. In addition, a chapter deals with aboriginal communities. The topic of environmental refugees is discussed, followed by an historical perspective into climate change policy in Canada. The author concludes with adaptation measures. Further emphasis must be placed on priority topics such as the estimation of future emissions and modelling of climate processes. refs., tabs., figs

    Skepticism toward climate change has a long tradition in the United States. We focus on mass media as the conveyors of the image of climate change and ask: Is climate change skepticism still a characteristic of US print media coverage? If so, to what degree and in what form? And which factors might pave the way for skeptics entering mass media debates? We conducted a quantitative content analysis of US print media during one year (1 June 2012 to 31 May 2013). Our results show that the debate has changed: fundamental forms of climate change skepticism (such as denial of anthropogenic causes) have been abandoned in the coverage, being replaced by more subtle forms (such as the goal to avoid binding regulations). We find no evidence for the norm of journalistic balance, nor do our data support the idea that it is the conservative press that boosts skepticism.

    Full Text Available The article presents an overview and analysis of international legal regulations on climate change. The authors examine how the international regime related to climate change has evolved in multilateral agreements. A special focus is put on the principle of common but differentiated responsibilities which became the basis of discord among states in discussing targets and responsibilities in climate change mitigation. The authors note that in 2015 the international climate change regime entered a new stage where the most important role is determined for developing countries, both in the legal and in the financial infrastructure, and in the formation of an international climate change policy.The importance of the participation of Brazil, Russia, India, China, and South Africa (BRICS in an international climate change regime has been recognized for some time. The article describes the policy and regulations on climate-related issues in BRICS. The authors compare the key actions and measures BRICS have taken for complying with international climate change documents. They highlight that global climate change action cannot be successful without BRICS countries’ involvement. BRICS must therefore make adequate efforts in emissions reduction measures and significant commitments in respect of the international climate change regime. The authors propose three major steps for BRICS to take the lead in dealing with climate change. First, BRICS need to foster further discussion and cooperation on climate issues and work out an obligatory legal framework to fight climate change collectively as well as unified legislation at their domestic levels. Second, Russia and other BRICS countries have the potential to cooperate in the field of renewable energy through the exchange of technology, investment in the sector, and the participation of their energy companies in each other’s domestic market.

  17. The essential interactions between understanding climate variability and climate change

    Science.gov (United States)

    Neelin, J. D.

    2017-12-01

    Global change is sometimes perceived as a field separate from other aspects of atmospheric and oceanic sciences. Despite the long history of communication between the scientific communities studying global change and those studying interannual variability and weather, increasing specialization and conflicting societal demands on the fields can put these interactions at risk. At the same time, current trajectories for greenhouse gas emissions imply substantial adaptation to climate change will be necessary. Instead of simply projecting effects to be avoided, the field is increasingly being asked to provide regional-level information for specific adaptation strategies—with associated requirements for increased precision on projections. For extreme events, challenges include validating models for rare events, especially for events that are unprecedented in the historical record. These factors will be illustrated with examples of information transfer to climate change from work on fundamental climate processes aimed originally at timescales from hours to interannual. Work to understand the effects that control probability distributions of moisture, temperature and precipitation in historical weather can yield new factors to examine for the changes in the extremes of these distributions under climate change. Surprisingly simple process models can give insights into the behavior of vastly more complex climate models. Observation systems and model ensembles aimed at weather and interannual variations prove valuable for global change and vice versa. Work on teleconnections in the climate system, such as the remote impacts of El Niño, is informing analysis of projected regional rainfall change over California. Young scientists need to prepare to work across the full spectrum of climate variability and change, and to communicate their findings, as they and our society head for future that is more interesting than optimal.

  18. Public Perception of Uncertainties Within Climate Change Science.

    2018-01-01

    Climate change is a complex, multifaceted problem involving various interacting systems and actors. Therefore, the intensities, locations, and timeframes of the consequences of climate change are hard to predict and cause uncertainties. Relatively little is known about how the public perceives this scientific uncertainty and how this relates to their concern about climate change. In this article, an online survey among 306 Swiss people is reported that investigated whether people differentiate between different types of uncertainty in climate change research. Also examined was the way in which the perception of uncertainty is related to people's concern about climate change, their trust in science, their knowledge about climate change, and their political attitude. The results of a principal component analysis showed that respondents differentiated between perceived ambiguity in climate research, measurement uncertainty, and uncertainty about the future impact of climate change. Using structural equation modeling, it was found that only perceived ambiguity was directly related to concern about climate change, whereas measurement uncertainty and future uncertainty were not. Trust in climate science was strongly associated with each type of uncertainty perception and was indirectly associated with concern about climate change. Also, more knowledge about climate change was related to less strong perceptions of each type of climate science uncertainty. Hence, it is suggested that to increase public concern about climate change, it may be especially important to consider the perceived ambiguity about climate research. Efforts that foster trust in climate science also appear highly worthwhile. © 2017 Society for Risk Analysis.

    The international issue of climate change was discussed at this AREA (Alliance for Responsible Environmental Alternatives) conference. AREA, a coalition of industry, labour and municipalities from across Canada, was created to reflect the views and represent the interest of Canadians in the Climate Change debate. The role that Canada should play to optimize Canada's response to the Global Climate Change Challenge at the Kyoto Conference was the principal topic of discussion. Specific topics for panel discussions included the economic impacts of climate change, the effectiveness of voluntary mechanisms to reduce greenhouse gases versus government-mandated actions for achieving climate change targets, the issue of how a differentiated system for emission reduction targets and timetables might be implemented, the economic imperatives and the effect of those imperatives on negotiating positions at Kyoto, and various national agendas and the likely outcomes at Kyoto. tabs., figs

    2013-07-01

    The agricultural sector is highly vulnerable to future climate changes and climate variability, including increases in the incidence of extreme climate events. Changes in temperature and precipitation will result in changes in land and water regimes that will subsequently affect agricultural productivity. Given the gradual change of climate in the past, historically, farmers have adapted in an autonomous manner. However, with large and discrete climate change anticipated by the end of this century, planned and transformational changes will be needed. In light of these, the focus of this review is on farm-level and farmers responses to the challenges of climate change both spatially and over time. In this review of adapting agriculture to climate change, the nature, extent, and causes of climate change are analyzed and assessed. These provide the context for adapting agriculture to climate change. The review identifies the binding constraints to adaptation at the farm level. Four major priority areas are identified to relax these constraints, where new initiatives would be required, i.e., information generation and dissemination to enhance farm-level awareness, research and development (R&D) in agricultural technology, policy formulation that facilitates appropriate adaptation at the farm level, and strengthening partnerships among the relevant stakeholders. Forging partnerships among R&D providers, policy makers, extension agencies, and farmers would be at the heart of transformational adaptation to climate change at the farm level. In effecting this transformational change, sustained efforts would be needed for the attendant requirements of climate and weather forecasting and innovation, farmer's training, and further research to improve the quality of information, invention, and application in agriculture. The investment required for these would be highly significant. The review suggests a sequenced approach through grouping research initiatives into short

    2013-12-01

    Researchers have found that a deficit model of knowledge doesn't fully explain why some people continue to deny that climate change is happening or that human activity is to blame. Recent work in science education has focused our attention on the need to go beyond simply communicating what we know about climate change to how we know it. That is, allowing and encouraging students to grapple with the processes that scientists have gone through to make their claims builds deeper understanding of why the consensus around climate change is strong, where uncertainties remain, and how to think about implications for society and themselves. This suggests that teachers need to provide scaffolding that builds not only students' understanding of how climate systems work or the causes and effects of climate change but also their capacity to evaluate the scientific evidence behind these claims. What is the evidence for anthropogenic climate change? What data are missing or currently being collected? How sure are scientists about their claims? What claim can be made from a particular set of data? And conversely, what claim cannot be made given these data? Climate change education provides not only an excellent opportunity to integrate science content with such scientific practices, but also an imperative to do so. In this study, we explore how students and teachers may engage collectively in this process of argumentation in order to arrive at a conclusion or claim supported by evidence. We take the position that learning to construct and evaluate arguments involves growth in scientific practices and meta-procedural (epistemic) knowledge This work was conducted over the course of three years through the NASA-funded Stanford Global Climate Change project. Scientists and educators provided teacher professional development on the science of global climate change, pedagogical strategies, and curriculum materials that emphasize both what we know about climate change and we how know it

    Goal 9 of the LANL FY15 Site Sustainability Plan (LANL 2014a) addresses Climate Change Adaptation. As part of Goal 9, the plan reviews many of the individual programs the Laboratory has initiated over the past 20 years to address climate change impacts to LANL (e.g. Wildland Fire Management Plan, Forest Management Plan, etc.). However, at that time, LANL did not yet have a comprehensive approach to climate change adaptation. To fill this gap, the FY15 Work Plan for the LANL Long Term Strategy for Environmental Stewardship and Sustainability (LANL 2015) included a goal of (1) establishing a comprehensive conceptual model of climate change impacts at LANL and (2) establishing specific climate change indices to measure climate change and impacts at Los Alamos. Establishing a conceptual model of climate change impacts will demonstrate that the Laboratory is addressing climate change impacts in a comprehensive manner. This paper fulfills the requirement of goal 1. The establishment of specific indices of climate change at Los Alamos (goal 2), will improve our ability to determine climate change vulnerabilities and assess risk. Future work will include prioritizing risks, evaluating options/technologies/costs, and where appropriate, taking actions. To develop a comprehensive conceptual model of climate change impacts, we selected the framework provided in the National Oceanic and Atmospheric Administration (NOAA) Climate Resilience Toolkit (http://toolkit.climate.gov/).

    Global climate change has multidimensional impacts with several biological fingerprints, and treeline shifting in tandem with climate change is a widely observed phenomenon in various parts of the world. In Nepal several impacts of climate change on physical environments have been observed. However, studies on the biological impacts are lacking. This dendrochronological study was carried out at the treeline ecotone (3750-4003 m a.s.l.) in the Kalchuman Lake (Kal Tal) area of the Manaslu Conservation Area in central Nepal Himalaya with the aim to study the dynamic impact of climate change at the treeline. The study provides an insight into regeneration and treeline dynamics over the past 200 yr. Two belt transect plots (size: 20 m wide, >250 m long) were laid covering forest line, treeline as well as tree species Abies spectabilis and Betula utilis was done and their tree-cores were collected. Stand character and age distribution revealed an occurrence of more matured B. utilis (max. age 198 yr old) compared to A. spectabilis (max. age 160 yr). A. spectabilis contained an overwhelmingly high population (89%) of younger plants (plant density as well as upward shifting in the studied treeline ecotones was observed. Thus, two species presented species-specific responses to climate change and much wider differences anticipated in their population status as climate continues to cha spectabilis correlated negatively with the mean monthly temperature of May-August of the current year and with September of the previous year. The regeneration of A. spectabilis, on the other hand, was positively related with May-August precipitation and January-April temperature of the current year. The reconstructed average summer temperature (May-August) using tree ring data revealed alternate period of cool and warm period with warming in the 2nd half of the 20th century. Further palynological and geochronological studies of sediments of the Kalchuman Lake would advance our understanding

    Climate change is expected to increase winter rainfall and flooding in many extratropical regions as evaporation and precipitation rates increase, storms become more intense and storm tracks move polewards. Here, we show how changes in stratospheric circulation could play a significant role in future climate change in the extratropics through an additional shift in the tropospheric circulation. This shift in the circulation alters climate change in regional winter rainfall by an amount large enough to significantly alter regional climate change projections. The changes are consistent with changes in stratospheric winds inducing a change in the baroclinic eddy growth rate across the depth of the troposphere. A change in mean wind structure and an equatorward shift of the tropospheric storm tracks relative to models with poor stratospheric resolution allows coupling with surface climate. Using the Atlantic storm track as an example, we show how this can double the predicted increase in extreme winter rainfall over Western and Central Europe compared to other current climate projections.

    Anthropogenic climate change will have significant impacts on both human migration and population health, including infectious disease. It will amplify and alter migration pathways, and will contribute to the changing ecology and transmission dynamics of infectious disease. However there has been limited consideration of the intersections between migration and health in the context of a changing climate. This article argues that climate-change related migration - in conjunction with other drivers of migration - will contribute to changing profiles of infectious disease. It considers infectious disease risks for different climate-related migration pathways, including: forced displacement, slow-onset migration particularly to urban-poor areas, planned resettlement, and labor migration associated with climate change adaptation initiatives. Migration can reduce vulnerability to climate change, but it is critical to better understand and respond to health impacts - including infectious diseases - for migrant populations and host communities.

    Climate change is the defining challenge of our time”. This statement by UN Secretary General Ban Ki Moon (2009) is still valid. The challenges of food shortage, environmental degradation and natural disasters are to a large extent caused by the overarching challenge of climate change, while...... the rapid urbanisation is a general trend that in itself has a significant impact on climate change. Measures for adaptation to climate change must be integrated into strategies for poverty reduction to ensure sustainable development and for meeting the Millennium Development Goals and beyond. Sustainable...... monitoring systems and systems for land administration and management should serve as a basis for climate change mitigation and adaptation as well as prevention and management of natural disasters. In facing the climate change challenge the role of land professionals is twofold: • Monitoring change...

    2017-12-01

    An on-going 5-yr project financially supported by the Ministry of Environment, Japan, has been carried out to specifically address the issue of prescribing appropriate adaptation and mitigation measures to climate change in cities. Entitled "Case Study on Mitigation and Local Adaptation to Climate Change in an Asian Megacity, Jakarta", the project's relevant objectives is to develop a research framework that can consider both urbanization and climate change with the main advantage of being readily implementable for all cities around the world. The test location is the benchmark city, Jakarta, Indonesia, with the end focus of evaluating the benefits of various mitigation and adaptation strategies in Jakarta and other megacities. The framework was designed to improve representation of urban areas when conducting climate change investigations in cities; and to be able to quantify separately the impacts of urbanization and climate change to all cities globally. It is comprised of a sophisticated, top-down, multi-downscaling approach utilizing a regional model (numerical weather model) and a microscale model (energy balance model and CFD model), with global circulation models (GCM) as input. The models, except the GCM, were configured to reasonably consider land cover, urban morphology, and anthropogenic heating (AH). Equally as important, methodologies that can collect and estimate global distribution of urban parametric and AH datasets are continually being developed. Urban growth models, climate scenario matrices that match representative concentration pathways with shared socio-economic pathways, present distribution of socio-demographic indicators such as population and GDP, existing GIS datasets of urban parameters, are utilized. From these tools, future urbanization (urban morphological parameters and AH) can be introduced into the models. Sensitivity using various combinations of GCM and urbanization can be conducted. Furthermore, since the models utilize

    2007-01-01

    The purpose of this report is to provide an up-to-date assessment of observed climate change over Australia, the likely causes, and projections of future changes to Australia's climate. It also provides information on how to apply the projections in impact studies and in risk assessments. The two main strategies for managing climate risk are mitigation (net reductions in greenhouse gas emissions) to slow climate change and adaptation to climate impacts that are unavoidable. A number of major advances have been made since the last report on climate change projections in Australia (CSIRO 2001) including: a much larger number of climate and ocean variables are projected (21 and 6 respectively); a much larger number (23) of climate models are used; the provision of probabilistic information on some of the projections, including the probability of exceeding the 10th, 50th and 90th percentiles; greater emphasis on projections from models that are better able to simulate observed Australian climate; a detailed assessment of observed changes in Australian climate and likely causes; and information on risk assessment, to provide guidance for using climate projections in impact studies

    2004-01-01

    Global abrupt climate changes have been documented by various climate records, including ice cores,ocean sediment cores, lake sediment cores, cave deposits,loess deposits and pollen records. The climate system prefers to be in one of two stable states, i.e. interstadial or stadial conditions, but not in between. The transition between two states has an abrupt character. Abrupt climate changes are,in general, synchronous in the northern hemisphere and tropical regions. The timescale for abrupt climate changes can be as short as a decade. As the impacts may be potentially serious, we need to take actions such as reducing CO2emissions to the atmosphere.

    2005-01-01

    Amphibian life histories are exceedingly sensitive to temperature and precipitation, and there is good evidence that recent climate change has already resulted in a shift to breeding earlier in the year for some species. There are also suggestions that the recent increase in the occurrence of El Niño events has caused declines of anurans in Central America and is linked to elevated mortality of amphibian embryos in the northwestern United States. However, evidence linking amphibian declines in Central America to climate relies solely on correlations, and the mechanisms underlying the declines are not understood. Connections between embryo mortality and declines in abundance have not been demonstrated. Analyses of existing data have generally failed to find a link between climate and amphibian declines. It is likely, however, that future climate change will cause further declines of some amphibian species. Reduced soil moisture could reduce prey species and eliminate habitat. Reduced snowfall and increased summer evaporation could have dramatic effects on the duration or occurrence of seasonal wetlands, which are primary habitat for many species of amphibians. Climate change may be a relatively minor cause of current amphibian declines, but it may be the biggest future challenge to the persistence of many species

    Three higher education institutions, University of Nebraska-Lincoln (UNL), Brooklyn College, and Lehman College, are working together to share expertise and resources to expand climate change topics offered to undergraduate and graduate students in New York City (NYC). This collaboration combines existing UNL educational learning resources and infrastructure in virtual coursework. It will supply global climate change education and locally-based research experiences to the highly diverse undergraduate students of Brooklyn and Lehman Colleges and to middle and high school teachers in NYC. Through the university partnership, UNL materials are being adapted and augmented to include authentic research experiences for undergraduates and teachers using NASA satellite data, geographic information system (GIS) tools, and/or locally collected microclimate data from urban gardens. Learners download NASA data, apply an Earth system approach, and employ GIS in the analysis of food production landscapes in a dynamically changing climate system. The resulting course will be offered via Blackboard courseware, supported by Web 2.0 technologies designed specifically to support dialogue, data, and web publication sharing between partners, teachers and middle school, high school and undergraduate student researchers. NYC is in the center of the urban farming movement. By exploring water and food topics of direct relevance to students' lives and community, we anticipate that students will be motivated and more empowered to make connections between climate change and potential impacts on the health and happiness of people in their community, in the United States and around the world. Final course will be piloted in 2012.

    2015-01-01

    The western United States is a region long defined by water challenges. Climate change adds to those historical challenges, but does not, for the most part, introduce entirely new challenges; rather climate change is likely to stress water supplies and resources already in many cases stretched to, or beyond, natural limits. Projections are for continued and, likely, increased warming trends across the region, with a near certainty of continuing changes in seasonality of snowmelt and streamflows, and a strong potential for attendant increases in evaporative demands. Projections of future precipitation are less conclusive, although likely the northernmost West will see precipitation increases while the southernmost West sees declines. However, most of the region lies in a broad area where some climate models project precipitation increases while others project declines, so that only increases in precipitation uncertainties can be projected with any confidence. Changes in annual and seasonal hydrographs are likely to challenge water managers, users, and attempts to protect or restore environmental flows, even where annual volumes change little. Other impacts from climate change (e.g., floods and water-quality changes) are poorly understood and will likely be location dependent.

  5. A climate for development. Climate change policy options for Africa

    1995-01-01

    The seriousness of the potential impacts of climate change on development in Africa is now well recognized within, and increasingly outside, scientific circles. The United Nations Framework Convention on Climate Change is a landmark in international environmental governance, providing a mechanism for exchange, negotiation and institution-building to re-direct development towards more efficient use of resources, especially energy. The message of 'A climate for Development' is that unless policy-makers fully understand both the international commitments made under the Convention and the essential national development priorities of their own countries, effective action on climate change is unlikely to be realized. The action needed, however, can at the same time stimulate capacity-building, planning and policy change which would strengthen the economic and ecological base of African countries. The climate change issue has hence brought us face to face with the urgency of the basic issues of sustainable development in Africa. The book discusses key issues that cut across all African countries, such as emissions and their impacts, financial resources and technology transfer for emissions abatement strategies. It then provides a sectoral analysis of greenhouse gas emissions and abatement options focusing on energy, industry, agriculture, forestry and transportation. The book concludes with guidelines for options which may be considered by African countries to ensure that climate change concerns are effectively dealt with in the context of their development priorities. 113 refs

    In the fall of 2013, 24 sophomore students enrolled in a three-course Learning Community entitled "The Ethics and Science of Climate Change." This learning community was comprised of two disciplinary courses in environmental ethics and environmental science as well as a seminar course in which the students designed and delivered climate change education events in the community beyond campus. Students were surveyed prior to and upon completion of the semester using a variant of the Yale Climate Literacy Survey in order to assess their knowledge of and attitudes towards climate change. An analysis of those survey results demonstrated that the non-traditional curriculum resulted in significant improvements that extended beyond disciplinary knowledge of climate change: the student attitudes about climate change and our cultural response to the issues associated with climate change shifted as well. Finally, a third administration of the survey (n=17) plus follow up interviews with 10 of those original students conducted during the students' senior year in 2016 suggest that the changes that the students underwent as sophomores were largely retained.

  7. Microhabitat and Climatic Niche Change Explain Patterns of Diversification among Frog Families.

    A major goal of ecology and evolutionary biology is to explain patterns of species richness among clades. Differences in rates of net diversification (speciation minus extinction over time) may often explain these patterns, but the factors that drive variation in diversification rates remain uncertain. Three important candidates are climatic niche position (e.g., whether clades are primarily temperate or tropical), rates of climatic niche change among species within clades, and microhabitat (e.g., aquatic, terrestrial, arboreal). The first two factors have been tested separately in several studies, but the relative importance of all three is largely unknown. Here we explore the correlates of diversification among families of frogs, which collectively represent ∼88% of amphibian species. We assemble and analyze data on phylogeny, climate, and microhabitat for thousands of species. We find that the best-fitting phylogenetic multiple regression model includes all three types of variables: microhabitat, rates of climatic niche change, and climatic niche position. This model explains 67% of the variation in diversification rates among frog families, with arboreal microhabitat explaining ∼31%, niche rates ∼25%, and climatic niche position ∼11%. Surprisingly, we show that microhabitat can have a much stronger influence on diversification than climatic niche position or rates of climatic niche change.

  8. Climate change impacts: an Ontario perspective

    1995-11-01

    Significant changes in the climate system which are likely to affect biophysical, social and economic systems in various ways, were discussed. Trends in greenhouse gas levels show that during the 20. century, human activity has changed the make-up of the atmosphere and its greenhouse effect properties. A pilot study on the impacts of climate change identified changes in the water regime such as declines in net basin supply, lake levels and outflows, as important concerns. These changes would have impacts on water quality, wetlands, municipal water supply, hydroelectric power generation, commercial shipping, tourism and recreation, and to a lesser extent, on food productions. Climate impact assessments suggest that world conditions will change significantly as a result. Those with less resources are likely to be most affected by climate change, and the impacts on other regions of the world will be more significant to Ontario than the direct impacts on Ontario itself. In an effort to keep pace with global changes, Ontario will have to limit emissions, conduct research in innovative technology and develop greater awareness of the risk of climate change. refs., tabs., figs

    In response to growing concern about human-induced global climate change, the UN Intergovernmental Panel on Climate Change (IPCC) was formed in 1988. Written by its first Chairman, this book is a unique overview of the history of the IPCC. It describes and evaluates the intricate interplay between key factors in the science and politics of climate change, the strategy that has been followed, and the regretfully slow pace in getting to grips with the uncertainties that have prevented earlier action being taken. The book also highlights the emerging conflict between establishing a sustainable global energy system and preventing a serious change in global climate. Contents are: Part I. The Early History of the Climate Change Issue: 1. Nineteenth century discoveries; 2. The natural carbon cycle and life on earth; 3. Global research initiatives in meteorology and climatology; 4. Early international assessments of climate change; Part II. The Climate Change Issue Becomes One of Global Concern: 5. Setting the stage; 6. The scientific basis for a climate convention; 7.

    Full Text Available Climate change is occurring as a result of warming of the earth’s atmosphere due to human activity generating excess amounts of greenhouse gases. Because of its potential impact on the hydrologic cycle and severe weather events, climate change is expected to have an enormous effect on human health, including on the burden and distribution of many infectious diseases. The infectious diseases that will be most affected by climate change include those that are spread by insect vectors and by contaminated water. The burden of adverse health effects due to these infectious diseases will fall primarily on developing countries, while it is the developed countries that are primarily responsible for climate change. It is up to governments and individuals to take the lead in halting climate change, and we must increase our understanding of the ecology of infectious diseases in order to protect vulnerable populations.

    Under a NASA grant, Mathematical and Geospatial Pathways to Climate Change Education, students at California State University, Northridge integrated Geographic Information Systems (GIS), remote sensing, satellite data technologies, and climate modelling into the study of global climate change under a Pathway for studying the Mathematics of Climate Change (PMCC). The PMCC, which is an interdisciplinary option within the BS in Applied Mathematical Sciences, consists of courses offered by the departments of Mathematics, Physics, and Geography and is designed to prepare students for careers and Ph.D. programs in technical fields relevant to global climate change. Under this option students are exposed to the science, mathematics, and applications of climate change science through a variety of methods including hands-on experience with computer modeling and image processing software. In the Geography component of the program, ESRI's ArcGIS and ERDAS Imagine mapping, spatial analysis and image processing software were used to explore NASA satellite data to examine the earth's atmosphere, hydrosphere and biosphere in areas that are affected by climate change or affect climate. These technology tools were incorporated into climate change and remote sensing courses to enhance students' knowledge and understanding of climate change through hands-on application of image processing techniques to NASA data. Several sets of exercises were developed with specific learning objectives in mind. These were (1) to increase student understanding of climate change and climate change processes; (2) to develop student skills in understanding, downloading and processing satellite data; (3) to teach remote sensing technology and GIS through applications to climate change; (4) to expose students to climate data and methods they can apply to solve real world problems and incorporate in future research projects. In the Math and Physics components of the course, students learned about

    Integration of social science into climate and global change assessments is fundamental for improving understanding of the drivers, impacts and vulnerability of climate change, and the social, cultural and behavioral challenges related to climate change responses. This requires disciplinary and interdisciplinary knowledge as well as integrational and translational tools for linking this knowledge with the natural and physical sciences. The USGCRP's Social Science Coordinating Committee (SSCC) is tasked with this challenge and is working to integrate relevant social, economic and behavioral knowledge into processes like sustained assessments. This presentation will discuss outcomes from a recent SSCC workshop, "Social Science Perspectives on Climate Change" and their applications to sustained assessments. The workshop brought academic social scientists from four disciplines - anthropology, sociology, geography and archaeology - together with federal scientists and program managers to discuss three major research areas relevant to the USGCRP and climate assessments: (1) innovative tools, methods, and analyses to clarify the interactions of human and natural systems under climate change, (2) understanding of factors contributing to differences in social vulnerability between and within communities under climate change, and (3) social science perspectives on drivers of global climate change. These disciplines, collectively, emphasize the need to consider socio-cultural, political, economic, geographic, and historic factors, and their dynamic interactions, to understand climate change drivers, social vulnerability, and mitigation and adaptation responses. They also highlight the importance of mixed quantitative and qualitative methods to explain impacts, vulnerability, and responses at different time and spatial scales. This presentation will focus on major contributions of the social sciences to climate and global change research. We will discuss future directions for

    Kenya Vision 2030 - the long-term development blueprint for the country - aims to transform Kenya into 'a newly industrialising, middle-income country providing a high quality of life to all its citizens in a clean and secure environment'. A low carbon climate resilient development pathway, as set out in this Climate Change Action Plan, can help meet Vision 2030 goals through actions that address both sustainable development and climate change. This pathway can also help the Government achieve the Millennium Development Goals and other internationally agreed development goals without compromising the environment and its natural resources. As Kenya realizes its development aspirations, there will be gains and risks. A growing population and economy with migration to cities will mean increases in greenhouse gas (GHG) emissions. Resulting environmental and social conditions, including increased competition over resources, could intensify vulnerability to climate risks. Transitioning to a low carbon climate resilient development pathway can address future risks thereby improving Kenya's ability to prosper under a changing climate while reducing the emissions intensity of a growing economy. Moving forward on the 2010 National Climate Change Response Strategy will help Kenya transition to a low carbon climate resilient development pathway that puts people and livelihoods at the forefront. The strategy recognized the importance of climate change and development, and this Climate Change Action Plan is the logical next step. A yearlong multistakeholder participatory process involving the public sector, private sector and civil society resulted in this Action Plan that identifies priority climate change actions for Kenya for the short, medium and long term. The Government of Kenya takes climate change and its impact on development seriously. Climate change is considered a crosscutting issue that will be mainstreamed in the planning process both at the national

    Full Text Available Changes to Earth’s climate are occurring globally at unprecedented rates with significant impacts to human and population health, including increased likelihood of mental health illnesses, food and water insecurity, insect-borne and heat-related illnesses, and respiratory diseases. Those in the health sector are seeing the challenges patients and community members are experiencing as a result of current and projected climate threats. Health professionals, including nurses, have an opportunity to lead the charge to significantly improve society’s response to climate change and foster the strategies needed to promote health. This article highlights the current work of the Alliance of Nurses for Healthy Environments, a national nursing organization focused solely on environmental health concerns, in inspiring and empowering nurses across the country to engage in action to reduce their climate impact, move climate solutions forward, and improve the ability of health care institutions and communities to respond to the health impacts of climate change.

  17. Public Inaccuracy in Meta-perceptions of Climate Change

    2012-12-01

    Public perceptions of climate change and meta-perceptions of the public and climate scientist's perceptions of climate change were assessed to benchmark the National Network for Climate Change Interpretation's impacts. Meta-perceptions are important to examine because they can have implications for willingness to take action to address climate change. For instance, recent research suggests a tendency to misperceive that there is disagreement among climate scientists is predictive of lack of support for climate change policies. Underestimating public concern about climate change could also be problematic: it could lead individuals to withdraw from personal efforts to reduce impact and engage others in discussions about climate change. Presented results will demonstrate that respondents in a national survey underestimated the percent of the public who were very concerned, concerned or cautious about climate change and overestimated the extent others were disengaged, doubted, or non-believers. They underestimated the percent of the public who likely believed that humans caused climate change and overestimate the percent that believed climate change was not happening nor human induced. Finally, they underestimated the percent of the public that believed climate change threatened ocean health. The results also explore sources of misperceptions. First, correlates with TV viewing habits suggest that inaccuracy is a result of too little attention to network news, with one exception: Greater attention to FOX among doubters reduced accuracy. Second, adding to other evidence that basic cognitive heuristics (such as availability heuristic) influence perceptions of climate change, we show that that false consensus effects account for meta-perceptions of the public and climate scientists beliefs. The false consensus effect, in combination with underestimating concern among the public, results in those most concerned about climate change and those who believe it to be human

    2012-12-01

    A robust understanding of the sensitivity of the pattern, structure, and dynamics of ecosystems to climate, climate variability, and climate change is needed to predict ecosystem responses to current and projected climate change. We present results of a study designed to first quantify the sensitivity of ecosystems to climate through the use of climate and ecosystem data, and then use the results to test the sensitivity of the climate data in a state-of the art ecosystem model. A database of available ecosystem characteristics such as mean canopy height, above ground biomass, and basal area was constructed from sources like the National Biomass and Carbon Dataset (NBCD). The ecosystem characteristics were then paired by latitude and longitude with the corresponding climate characteristics temperature, precipitation, photosynthetically active radiation (PAR) and dew point that were retrieved from the North American Regional Reanalysis (NARR). The average yearly and seasonal means of the climate data, and their associated maximum and minimum values, over the 1979-2010 time frame provided by NARR were constructed and paired with the ecosystem data. The compiled results provide natural patterns of vegetation structure and distribution with regard to climate data. An advanced ecosystem model, the Ecosystem Demography model (ED), was then modified to allow yearly alterations to its mechanistic climate lookup table and used to predict the sensitivities of ecosystem pattern, structure, and dynamics to climate data. The combined ecosystem structure and climate data results were compared to ED's output to check the validity of the model. After verification, climate change scenarios such as those used in the last IPCC were run and future forest structure changes due to climate sensitivities were identified. The results of this study can be used to both quantify and test key relationships for next generation models. The sensitivity of ecosystem characteristics to climate data

    Earlier this year, scientists warned that 'an increasing body of observations gives a collective picture of a warming world and other changes in the climate system'. The conclusion came from the third assessment report of the Intergovernmental Panel on Climate Change (IPCC). Today, it is widely accepted that recent warning is largely a product of enhanced greenhouse gas concentrations in the atmosphere derived from post-industrial combustion of fossil fuels and biomass energy sources. However, great uncertainty remains regarding the causal relationships between specific parameters and climate phenomena, and regarding the impacts of climate change on the earth's water cycle. The science of climate change is dynamic. The IAEA contributes to studies via coordination of climate research, participation and support for international scientific programmes, and dissemination of isotope technology and applications. The third quadrennial scientific gathering on the use of isotopes for studying environmental change was held at the IAEA in Vienna 23-27 April 2001. The Conference - attended by 150 experts from 38 countries and seven international organizations - served as an important forum for presentation of results, discussion of ideas and concepts, establishment of international collaboration, and identification of avenues for future research. Selected highlights of issues discussed include: Isotopes are being used as validation tools for predicting impacts of deforestation of the Amazon Basin and for examining the past isotope signals of El Nino events; Isotope signatures in ice cores from low-latitude environments are showing similar temperature signals to polar ice cores,suggesting widespread (global) changes in the past; Isotopes are being used in the World Ocean Circulation Experiment to trace the movement, mixing and residence time of oceanic circulation patterns. Changes in ocean circulation are one of the most important factors controlling the variability of the

    Whereas climate change will have significant consequences on various economic sectors (infrastructures, energy and water supply, agriculture, cities and buildings, and so on), population behaviours and uses will have to be deeply changed, and this is more particularly the case for enterprises and companies. This guide aims at presenting solutions to face the challenge of climate change for enterprises. In its first part, it outlines how our climate is already changing, gives an overview of main future climate trends in the World, indicates what will be the future climate in France, discusses the noticeable and brutal consequences for activities, resources and territories, outlines that adaptation to tomorrow's climate begins now, and discusses to which climate we'll have to adapt at the local level. In the second part, this publication explains why enterprises must adapt themselves to climate change: enterprises are in a changing environment, and must take a legal and standard framework into account, but this adaptation will have a cost. Adaptation also means uncertainty management, and enterprises are facing obstacles and brakes to adaptation. The last part describes how to implement a strategy of adaptation in an enterprise: resources for adaptation, integration of enterprise management, understanding needs to convince within the enterprise itself, assessment of vulnerability to climate change, how to define priorities for action, which options to choose to adapt the enterprise, how to implement the strategy and how to follow it up and assess it. Some sector-related sheets are provided in appendix. They indicate identified risks, potential impacts of national policies for enterprises, measures which can be freely implemented by enterprises, and identified opportunities for various sectors (health, agriculture, forest, coastal areas, fishery and aquaculture, energy and industry, transport infrastructure, town planning and built environment, tourism

    The 1992 United Nations Framework Convention on Climate Change is one of a series of recent agreements through which countries around the world are banding together to meet the challenge of altering the global climate. In 1997, in respond to the growing public pressure and questions on climate change governments adopted the Kyoto Protocol. The 5th Conference of the Parties to the UN Framework Convention on Climate Change (COP5 UNFCCC) was a rather technical and complex conference which focused in particular on the development of a detailed framework for the application of ''flexible mechanisms'' as laid down in the Kyoto Protocol. Young Generation Network as a part of the International Nuclear Forum at COP5 took part in the debate saying that nuclear is the part of the solution. (author)

    This document described the models that scientists use to investigate the links between climate change and health. It then reviewed the evidence for possible impacts of climate change on human health. Most models conceptualize that climate change will affect the health of British Columbians directly through physical and biological pathways, and indirectly through complex socio-economic and environmental pathways. The direct physical and biological pathways will be the easiest to investigate, monitor and attribute to climate change, while the indirect socio-economic pathways will be more complex to investigate but will have the most impact. This document also provided guidance for a program of research and policy directions to better predict future impacts of climate change on health in BC and to enhance adaptation to these changes. The document suggested that basic research is needed to develop a made in BC model and infrastructure for climate change and health investigations. Currently, rural and remote forestry-dependent and Aboriginal communities in mountain pine infected zones are particularly vulnerable. However, it was concluded that although there is strong evidence for shifts in climate in BC, no direct evidence exists on the impact of climate change on human health in BC. refs., tabs., figs

    According to the Intergovernmental Panel on Climate Change, global temperatures are expected to increase 1.1 to 6.4 degrees C during the 21st century and precipitation patterns will be altered by climate change (IPCC, 2007). Soils are intricately linked to the atmospheric/climate system through the carbon, nitrogen, and hydrologic cycles. Altered climate will, therefore, have an effect on soil processes and properties. Studies into the effects of climate change on soil processes and properties are still incomplete, but have revealed that climate change will impact soil organic matter dynamics including soil organisms and the multiple soil properties that are tied to organic matter, soil water, and soil erosion. The exact direction and magnitude of those impacts will be dependent on the amount of change in atmospheric gases, temperature, and precipitation amounts and patterns. Recent studies give reason to believe at least some soils may become net sources of atmospheric carbon as temperatures rise; this is particularly true of high latitude regions with permanently frozen soils. Soil erosion by both wind and water is also likely to increase. These soil changes will lead to both direct and indirect impacts on human health. Possible indirect impacts include temperature extremes, food safety and air quality issues, increased and/or expanded disease incidences, and occupational health issues. Potential direct impacts include decreased food security and increased atmospheric dust levels. However, there are still many things we need to know more about. How climate change will affect the nitrogen cycle and, in turn, how the nitrogen cycle will affect carbon sequestration in soils is a major research need, as is a better understanding of soil water-CO2 level-temperature relationships. Knowledge of the response of plants to elevated atmospheric CO2 given limitations in nutrients like nitrogen and phosphorus and how that affects soil organic matter dynamics is a critical

    Climate data created from historic climate observations are integral to most assessments of potential climate change impacts, and frequently comprise the baseline period used to infer species-climate relationships. They are often also central to downscaling coarse resolution climate simulations from General Circulation Models (GCMs) to project future climate scenarios at ecologically relevant spatial scales. Uncertainty in these baseline data can be large, particularly where weather observations are sparse and climate dynamics are complex (e.g. over mountainous or coastal regions). Yet, importantly, this uncertainty is almost universally overlooked when assessing potential responses of species to climate change. Here, we assessed the importance of historic baseline climate uncertainty for projections of species' responses to future climate change. We built species distribution models (SDMs) for 895 African bird species of conservation concern, using six different climate baselines. We projected these models to two future periods (2040-2069, 2070-2099), using downscaled climate projections, and calculated species turnover and changes in species-specific climate suitability. We found that the choice of baseline climate data constituted an important source of uncertainty in projections of both species turnover and species-specific climate suitability, often comparable with, or more important than, uncertainty arising from the choice of GCM. Importantly, the relative contribution of these factors to projection uncertainty varied spatially. Moreover, when projecting SDMs to sites of biodiversity importance (Important Bird and Biodiversity Areas), these uncertainties altered site-level impacts, which could affect conservation prioritization. Our results highlight that projections of species' responses to climate change are sensitive to uncertainty in the baseline climatology. We recommend that this should be considered routinely in such analyses. © 2016 John Wiley

  8. NASA's Earth Observing System: The Transition from Climate Monitoring to Climate Change Prediction

    King, Michael D.; Herring, David D.

    1998-01-01

    Earth's 4.5 billion year history is a study in change. Natural geological forces have been rearranging the surface features and climatic conditions of our planet since its beginning. There is scientific evidence that some of these natural changes have not only led to mass extinctions of species (e.g., dinosaurs), but have also severely impacted human civilizations. For instance, there is evidence that a relatively sudden climate change caused a 300-year drought that contributed to the downfall of Akkadia, one of the most powerful empires in the Middle-East region around 2200 BC. More recently, the "little ice age" from 1200-1400 AD forced the Vikings to abandon Greenland when temperatures there dropped by about 1.5 C, rendering it too difficult to grow enough crops to sustain the population. Today, there is compelling scientific evidence that human activities have attained the magnitude of a geological force and are speeding up the rate of global change. For example, carbon dioxide levels have risen 30 percent since the industrial revolution and about 40 percent of the world's land surface has been transformed by humans. We don't understand the cause-and-effect relationships among Earth's land, ocean, and atmosphere well enough to predict what, if any, impacts these rapid changes will have on future climate conditions. We need to make many measurements all over the world, over a long period of time, in order to assemble the information needed to construct accurate computer models that will enable us to forecast climate change. In 1988, the Earth System Sciences Committee, sponsored by NASA, issued a report calling for an integrated, long-term strategy for measuring the vital signs of Earth's climate system. The report urged that the measurements must all be intimately coupled with focused process studies, they must facilitate development of Earth system models, and they must be stored in an information system that ensures open access to consistent, long-term data

    1994-01-01

    An international Conference on the Economics of Climate Change was convened by the OECD and the International Energy Agency (IEA) in Paris, in June 1993. Participants included many of the world's foremost experts in the field, as well as representatives from business, labour, and other non-governmental organisations. The Conference sought to examine points of consensus and divergence among existing studies on the economics of climate change. Participants also focused on how economic analysis could contribute to meeting the obligations of OECD countries under the 1992 Framework Convention on Climate Change. Discussions centered on such topics as the economic costs and benefits of greenhouse gas mitigation strategies, the potential role of carbon taxes and other economic instruments in the policy mix, possibilities for technological change and diffusion, especially in the energy sector, and joint abatement action between industrialized and developing countries. This volume contains the papers presented at the Conference, as well as summaries of the subsequent discussions. It provides an overview of the 'state of the art' in the economics of climate change and several suggestions for future research. (author)

    This chapter assesses the response of mangrove ecosystems to possible outcomes of climate change, with regard to the following categories: (i) distribution, diversity, and community composition, (ii) physiology of flora and fauna, (iii) water budget, (iv) productivity and remineralization, (v) carbon storage in biomass and sediments, and (vi) the filter function for elements beneficial or harmful to life. These categories are then used to identify the regions most vulnerable to climate change. The four most important factors determining the response of mangrove ecosystems to climate change are sea level rise, an increase in frequency and/or intensity of storms, increases in temperature, and aridity. While these changes may be beneficial for some mangrove forests at latitudinal distribution limits, they will threaten forest structure and functions and related ecosystem services in most cases. The interaction of climate change with human interventions is discussed, as well as the effects on ecosystem services including possible adaptation and management options. The chapter closes with an outlook on knowledge gaps and priority research needed to fill these gaps.

    Climate change is raising challenging concerns for systematic conservation planning. Are methods based on the current spatial patterns of biodiversity effective given long-term climate change? Some conservation scientists argue that planning should focus on protecting the abiotic diversity in the landscape, which drives patterns of biological diversity, rather than focusing on the distribution of focal species, which shift in response to climate change. Climate is one important abiotic driver of biodiversity patterns, as different climates host different biological communities and genetic pools. We propose conservation networks that capture the full range of climatic diversity in a region will improve the resilience of biotic communities to climate change compared to networks that do not. In this study we used historical and future hydro-climate projections from the high resolution Basin Characterization Model to explore the utility of directly targeting climatic diversity in planning. Using the spatial planning tool, Marxan, we designed conservation networks to capture the diversity of climate types, at the regional and sub-regional scale, and compared them to networks we designed to capture the diversity of vegetation types. By focusing on the Conservation Lands Network (CLN) of the San Francisco Bay Area as a real-world case study, we compared the potential resilience of networks by examining two factors: the range of climate space captured, and climatic stability to 18 future climates, reflecting different emission scenarios and global climate models. We found that the climate-based network planned at the sub-regional scale captured a greater range of climate space and showed higher climatic stability than the vegetation and regional based-networks. At the same time, differences among network scenarios are small relative to the variance in climate stability across global climate models. Across different projected futures, topographically heterogeneous areas

    This research paper talks about the economic costs of climate change, as well as the costs involved in responding to climate change with alternative fuels. This paper seeks to show that climate change, although seemingly costly in the short run, will both save future generations trillions of dollars and serve as a good economic opportunity. Scientists have long argued that the fate of humanity depends on a shift towards renewable energy. However, this paper will make clear that there is also an economic struggle. By embracing alternative fuels, we will not only lessen the danger and the frequency of these natural disasters but also strengthen the world’s financial state. Although a common argument against responding to climate change is that it is too expensive to make the switch, this research shows that in the future, it will save millions of lives and trillions of dollars. The only question left for policymakers is whether they will grasp this energy source shift.

  15. Climate Change and Algal Blooms =

    Science.gov (United States)

    Lin, Shengpan

    Algal blooms are new emerging hazards that have had important social impacts in recent years. However, it was not very clear whether future climate change causing warming waters and stronger storm events would exacerbate the algal bloom problem. The goal of this dissertation was to evaluate the sensitivity of algal biomass to climate change in the continental United States. Long-term large-scale observations of algal biomass in inland lakes are challenging, but are necessary to relate climate change to algal blooms. To get observations at this scale, this dissertation applied machine-learning algorithms including boosted regression trees (BRT) in remote sensing of chlorophyll-a with Landsat TM/ETM+. The results show that the BRT algorithm improved model accuracy by 15%, compared to traditional linear regression. The remote sensing model explained 46% of the total variance of the ground-measured chlorophyll- a in the first National Lake Assessment conducted by the US Environmental Protection Agency. That accuracy was ecologically meaningful to study climate change impacts on algal blooms. Moreover, the BRT algorithm for chlorophyll- a would not have systematic bias that is introduced by sediments and colored dissolved organic matter, both of which might change concurrently with climate change and algal blooms. This dissertation shows that the existing atmospheric corrections for Landsat TM/ETM+ imagery might not be good enough to improve the remote sensing of chlorophyll-a in inland lakes. After deriving long-term algal biomass estimates from Landsat TM/ETM+, time series analysis was used to study the relations of climate change and algal biomass in four Missouri reservoirs. The results show that neither temperature nor precipitation was the only factor that controlled temporal variation of algal biomass. Different reservoirs, even different zones within the same reservoir, responded differently to temperature and precipitation changes. These findings were further

    The issue of climate change has attracted increasing business attention in the past decade. Whereas companies initially aimed primarily at influencing the policy debate, corporate strategies increasingly include economic responses. Existing classifications for climate change strategies however still reflect the political, non-market components. Using empirical information from the largest multinational companies worldwide, this article examines current market responses, focusing on the drivers (threats and opportunities) and the actions being taken by companies to address climate change. It also develops a typology of climate strategies that addresses the market dimensions, covering both the aim (strategic intent) and the degree of cooperation (form of organisation). The aim turns out to be either innovation or compensation, while the organisational arrangements to reach this objective can be oriented at the company level (internal), at companies' own supply chain (vertical) or at cooperation with other companies (competitors or companies in other sectors - horizontal). The typology can assist managers in deciding about the strategic option(s) they want to choose regarding climate change, also based on the insights offered by the paper about the current state of activities of other companies worldwide.

  17. An Investigation of Secondary Students' Mental Models of Climate Change and the Greenhouse Effect

    2018-03-01

    There are several studies dealing with students' conceptions on climate change, but most of them refer to understanding before instruction. In contrast, this study investigates students' conceptions and describes the levels of sophistication of their mental models on climate change and the greenhouse effect. The participants were 40 secondary students (grade 7) in Spain. As a method of data collection, a questionnaire was designed with open-ended questions focusing on the mechanism, causes, and actions that could be useful in reducing climate change. Students completed the same questionnaire before and after instruction. The students' conceptions and mental models were identified by an inductive and iterative analysis of the participants' explanations. With regard to the students' conceptions, the results show that they usually link climate change to an increase in temperature, and they tend to mention, even after instruction, generic actions to mitigate climate change, such as not polluting. With regard to the students' mental models, the results show an evolution of models with little consistency and coherence, such as the models on level 1, towards higher levels of sophistication. The paper concludes with educational implications proposed for solving learning difficulties regarding the greenhouse effect and climate change.

    Global climate change is increasingly relevant in managing Canada’s forests sustainably. Forest managers are faced with the necessity of incorporating climate change into forest management plans. The formulation and evaluation of potential management strategies to contend with expected impacts of climate change will be necessary to reduce forest sector vulnerability. The Halifax Regional Water Commission manages forest watersheds for the purpose of supplying clean water to much of the Halifax Regional Municipality. The purpose of this study is to characterize the future forest structure of the two principal watersheds supplying the Halifax Regional Municipality using simulation modelling and to develop a framework of adaptive forest management. A combination of uncertainty analysis, sensitivity analysis, and field data collection are used to refine, calibrate, and validate the spatially dynamic landscape disturbance model LANDIS-II prior to the incorporation of climate change scenarios into model simulations. Final model-based analysis will inform framework development dedicated to improving watershed resilience in the face of future climate change. This study is applicable to forest management under a changing climate, but also has further significance to water security, as watershed management and point-source protection are tightly linked to forest management.

    The aims of the US Department of Energy's Carbon Dioxide Research Program are to improve assessments of greenhouse-gas-induced climatic change and to define and reduce uncertainties through selected research. This project will address: The regional and seasonal details of the expected climatic changes; how rapidly will these changes occur; how and when will the climatic effects of CO 2 and other greenhouse gases be first detected; and the relationships between greenhouse-gas-induced climatic change and changes caused by other external and internal factors. The present project addresses all of these questions. Many of the diverse facets of greenhouse-gas-related climate research can be grouped under three interlinked subject areas: modeling, first detection and supporting data. This project will include the analysis of climate forcing factors, the development and refinement of transient response climate models, and the use of instrumental data in validating General Circulation Models (GCMs)

    2013-09-01

    With ongoing and rapid climate change, ecologists are being challenged to predict how individual species will change in abundance and distribution, how biotic communities will change in structure and function, and the consequences of these climate-induced changes for ecosystem functioning. It is now well documented that indirect effects of climate change on species abundances and distributions, via climatic effects on interspecific interactions, can outweigh and even reverse the direct effects of climate. However, a clear framework for incorporating species interactions into projections of biological change remains elusive. To move forward, we suggest three priorities for the research community: (1) utilize tractable study systems as case studies to illustrate possible outcomes, test processes highlighted by theory, and feed back into modeling efforts; (2) develop a robust analytical framework that allows for better cross-scale linkages; and (3) determine over what time scales and for which systems prediction of biological responses to climate change is a useful and feasible goal. We end with a list of research questions that can guide future research to help understand, and hopefully mitigate, the negative effects of climate change on biota and the ecosystem services they provide. © 2013 New York Academy of Sciences.

    Climate change adaptation reduces adverse effects of climate change but may also have undesirable environmental impacts. However, these impacts are yet poorly defined and analysed in the existing literature. To complement this knowledge-gap, we reviewed the literature to unveil the relationship between climate change adaptation and environmental impact assessment, and the degree to which environmental impacts are included in climate change adaptation theory and practice. Our literature review showed that technical, social and economic perspectives on climate change adaptation receive much more attention than the environmental perspective. The scarce interest on the environmental impacts of adaptation may be attributed to (1) an excessive sectoral approach, with dominance of non-environmental perspectives, (2) greater interest in mitigation and direct climate change impacts rather than in adaptation impacts, (3) a tendency to consider adaptation as inherently good, and (4) subjective/preconceived notions on which measures are good or bad, without a comprehensive assessment. Environmental Assessment (EA) has a long established history as an effective tool to include environment into decision-making, although it does not yet guarantee a proper assessment of adaptation, because it is still possible to postpone or even circumvent the processes of assessing the impacts of climate adaptation. Our results suggest that there is a need to address adaptation proactively by including it in EA, to update current policy frameworks, and to demand robust and reliable evaluation of alternatives. Only through the full EA of adaptation measures can we improve our understanding of the primary and secondary impacts of adaptation to global environmental change. - Highlights: • Climate change adaptation may have undesirable environmental impacts. • The impacts of adaptation are yet poorly analysed in the literature. • There is an excessive sectoral approach to adaptation, mainly

Only through the full EA of adaptation measures can we improve our understanding of the primary and secondary impacts of adaptation to global environmental change. - Highlights: • Climate change adaptation may have undesirable environmental impacts. • The impacts of adaptation are yet poorly analysed in the literature. • There is an excessive sectoral approach to adaptation, mainly

    In November 2014, The European Centre for Medium-range Weather Forecasts (ECMWF) signed an agreement with the European Commission to deliver two of the Copernicus Earth Observation Programme Services on the Commission's behalf. The ECMWF delivered services - the Copernicus Climate Change Service (C3S) and Atmosphere Monitoring Service (CAMS) - will bring a consistent standard to how we measure and predict atmospheric conditions and climate change. They will maximise the potential of past, current and future earth observations - ground, ocean, airborne, satellite - and analyse these to monitor and predict atmospheric conditions and in the future, climate change. With the wealth of free and open data that the services provide, they will help business users to assess the impact of their business decisions and make informed choices, delivering a more energy efficient and climate aware economy. These sound investment decisions now will not only stimulate growth in the short term, but reduce the impact of climate change on the economy and society in the future. C3S is in its proof of concept phase and through its climate data store will provide global and regional climate data reanalyses; multi-model seasonal forecasts; customisable visual data to enable examination of wide range of scenarios and model the impact of changes; access to all the underlying data, including climate data records from various satellite and in-situ observations. In addition, C3S will provide key indicators on climate change drivers (such as carbon dioxide) and impacts (such as reducing glaciers). The aim of these indicators will be to support European adaptation and mitigation policies in a number of economic sectors. The presentation will provide an overview of this newly created Service, its various components and activities, and a roadmap towards achieving a fully operational European Climate Service at the horizon 2019-2020. It will focus on the requirements for quality-assured Observation

  5. Biotic and Biogeochemical Feedbacks to Climate Change

    Feedbacks to paleoclimate change are evident in ice core records showing correlations of temperature with carbon dioxide, nitrous oxide, and methane. Such feedbacks may be explained by plant and microbial responses to climate change, and are likely to occur under impending climate warming, as evidenced by results of ecosystem climate manipulation experiments and biometeorological observations along ecological and climate gradients. Ecosystems exert considerable influence on climate, by controlling the energy and water balance of the land surface as well as being sinks and sources of greenhouse gases. This presentation will focus on biotic and biogeochemical climate feedbacks on decadal to century time scales, emphasizing carbon storage and energy exchange. In addition to the direct effects of climate on decomposition rates and of climate and CO2 on plant productivity, climate change can alter species composition; because plant species differ in their surface properties, productivity, phenology, and chemistry, climate-induced changes in plant species composition can exert a large influence on the magnitude and sign of climate feedbacks. We discuss the effects of plant species on ecosystem carbon storage that result from characteristic differences in plant biomass and lifetime, allocation to roots vs. leaves, litter quality, microclimate for decomposition and the ultimate stabilization of soil organic matter. We compare the effect of species transitions on transpiration, albedo, and other surface properties, with the effect of elevated CO2 and warming on single species' surface exchange. Global change models and experiments that investigate the effect of climate only on existing vegetation may miss the biggest impacts of climate change on biogeochemical cycling and feedbacks. Quantification of feedbacks will require understanding how species composition and long-term soil processes will change under global warming. Although no single approach, be it experimental

    2013-12-01

    Full Text Available This paper uses the World Trade Model with Climate Sensitive Land (WTMCL to evaluate possible future land-use changes associated with adaptations to climate change in a globalized world. In this approach, changes in regional agricultural production, which are based on comparative advantage, define patterns of land use change in agriculture in all regions of the world. We evaluate four scenarios that combine assumptions about future increases in food demand and future changes in land endowments of different productivities associated with climatic conditions: each scenario generates distinct patterns of regional specialization in the production of agricultural commodities and associated land-use change. The analysis also projects future food availability under the simulated conditions and the direction of likely changes in prices of the major agricultural commodity groups.

    This paper outlines a roadmap to effective urban climate change adaptation built from our practical understanding of the evidence and effects of climate change and the preparation of climate change adaptation strategies and plans. This roadmap aims to drive research in achieving fruitful knowledge and solution-based achievable recommendations in adapting to climate change in urban areas with effective and systematic manner. This paper underscores the importance of the interplay between local government initiatives and a national government for effective adaptation to climate change and takes into account the policy process and politics. This paper argues that effective urban climate change adaptation has a contribution to build urban resilience and helps the achievement of national government goals and targets in climate change adaptation.

    2018-06-01

    Studies have tested whether model predictions based on species' occurrence can predict the spatial pattern of population abundance. The relationship between predicted environmental suitability and population abundance varies in shape, strength and predictive power. However, little attention has been paid to the congruence in predictions of different models fed with occurrence or abundance data, in particular when comparing metrics of climate change impact. Here, we used the ecological niche modeling fit with presence-absence and abundance data of orchid bees to predict the effect of climate change on species and assembly level distribution patterns. In addition, we assessed whether predictions of presence-absence models can be used as a proxy to abundance patterns. We obtained georeferenced abundance data of orchid bees (Hymenoptera: Apidae: Euglossina) in the Brazilian Atlantic Forest. Sampling method consisted in attracting male orchid bees to baits of at least five different aromatic compounds and collecting the individuals with entomological nets or bait traps. We limited abundance data to those obtained by similar standard sampling protocol to avoid bias in abundance estimation. We used boosted regression trees to model ecological niches and project them into six climate models and two Representative Concentration Pathways. We found that models based on species occurrences worked as a proxy for changes in population abundance when the output of the models were continuous; results were very different when outputs were discretized to binary predictions. We found an overall trend of diminishing abundance in the future, but a clear retention of climatically suitable sites too. Furthermore, geographic distance to gained climatic suitable areas can be very short, although it embraces great variation. Changes in species richness and turnover would be concentrated in western and southern Atlantic Forest. Our findings offer support to the ongoing debate of suitability

    Understanding the causes, effects, risks, and developing the social will and skills for responses to global change is a major challenge of the 21st century that requires coordinated contributions from the sciences, social sciences, humanities, arts, and beyond. There have been many effective efforts to implement climate change education, civic engagement and related workforce development programs focused on a multitude of audiences, topics and in multiple regions. This talk will focus on how comprehensive educational efforts across our communities are needed to support cities and their primary industries as they prepare for, and embrace, a low-carbon economy and develop the related workforce.While challenges still exist in identifying and coordinating all stakeholders, managing and leveraging resources, and resourcing and scaling effective programs to increase impact and reach, climate and energy literacy leaders have developed initiatives with broad input to identify the understandings and structures for climate literacy collective impact and to develop regional/metropolitan strategy that focuses its collective impact efforts on local climate issues, impacts and opportunities. This Climate Literacy initiative envisions education as a central strategy for community's civic actions in the coming decades by key leaders who have the potential to foster the effective and innovative strategies that will enable their communities to seize opportunity and prosperity in a post-carbon and resilient future. This talk discusses the advances and collaborations in the Climate Change Education community over the last decade by U.S. federal and non-profit organization that have been made possible through the partnerships of the Climate Literacy & Energy Awareness Network (CLEAN), U.S. National Science Foundation funded Climate Change Education Partnership (CCEP) Alliance, and the Tri-Agency Climate Change Education Collaborative.

    Manifold linkages exist between climate change and sustainable development. Although these are starting to receive attention in the climate exchange literature, the focus has typically been on examining sustainable development through a climate change lens, rather than vice versa. And there has been little systematic examination of how these linkages may be fostered in practice. This paper examines climate change through a sustainable development lens. To illustrate how this might change the approach to climate change issues, it reports on the findings of a panel of business, local government, and academic representatives in British Columbia, Canada, who were appointed to advise the provincial government on climate change policy. The panel found that sustainable development may offer a significantly more fruitful way to pursue climate policy goals than climate policy itself. The paper discusses subsequent climate change developments in the province and makes suggestions as how best to pursue such a sustainability approach in British Columbia and other jurisdictions

    2004-01-01

    This paper presents a conceptual framework of the impact of climate change on agriculture. It assumes that climate change will result in a fertilization effect and a shift of agro-ecological conditions away from the Equator towards the Poles. The agro-ecological shift is likely to reduce yield because of reduced acreage and the fertilization effect will increase yield. The aggregate effect depends on whichever of the two dominates. The overall effect of climate change may be less significant than its distributional effects and the results are consistent with previous empirical studies. The impact of climate change depends on its pace. Faster changes in climate will result in higher cost. The assessment of the cost has to consider that climate change is a dynamic phenomenon that may require continuous adjustment. Environmental regulation that emphasizes conservation may increase cost of adjustment and environmental policies should emphasize adaptation and flexibility

    Climate change is a global environmental issue which is the subject of intergovernmental negotiations in the United Nations system. The World Commission on Environment and Development (WCED) recommended to the UN General Assembly a four-track strategy relating to climate change: improved monitoring and assessment; increased research; development of internationally agreed policies to reduce greenhouse gases; and adoption of strategies to minimize impacts of climate change. The UN hosted a Conference on Environment and Development (UNCED) in Rio de Janeiro, Brazil, in June 1992 to attempt to find a common basis for action to protect the Earth's future and to secure a sustainable and equitable process of development. The focal point for UNCED efforts related to climate change is the Protection of the Atmosphere chapter of Agenda 21. Program A of this agenda contains responses to the WCED recommendations and Program B includes promotion of sustainable development in energy development, transportation, industry, and resource development. A framework convention on climate change was developed by an Intergovernmental Negotiating Committee established in 1990 and adopted by 130-140 countries. This convention includes general and specific obligations such as stabilization and control of greenhouse gas concentrations, development of emission inventories, and provision of financial resources to aid developing countries in responding to the climate change problem. 3 refs

    Full Text Available The current paper investigates the medium term economic impact of climate changes on the EU agriculture. The yield change data under climate change scenarios are taken from the BIOMA (Biophysical Models Application simulation environment. We employ CAPRI modelling framework to identify the EU aggregate economic effects as well as regional impacts. We take into account supply and market price adjustments of the EU agricultural sector as well as technical adaptation of crops to climate change. Overall results indicate an increase in yields and production level in the EU agricultural sector due to the climate change. In general, there are relatively small effects at the EU aggregate. For example, the value of land use and welfare change by approximately between -2% and 0.2%. However, there is a stronger impact at regional level with some stronger effects prevailing particularly in the Central and Northern EU and smaller impacts are observed in Southern Europe. Regional impacts of climate change vary by a factor higher up to 10 relative to the aggregate EU impacts. The price adjustments reduce the response of agricultural sector to climate change in particular with respect to production and income changes. The technical adaption of crops to climate change may result in a change production and land use by a factor between 1.4 and 6 relative to no-adaptation situation.

    Europe sees itself on the forefront to combat climate change. Consequently, the European Union has adopted in 2003 a Directive on Emissions Trading and since then, focuses more and more on effective methods to reduce greenhouse gas emissions. So far, there is little knowledge about the further development of Climate Change Policy in Europe after 2012. The EU has already started a review process to define the new legislation starting in 2013. Furthermore, negotiations take place to develop a successor of the Kyoto protocol. The European energy sector can deliver valuable input to the discussion about the coming climate goals and how to achieve them, by addressing the importance of new climate-friendly technologies. Furthermore, the impact of climate change goals on the current investment decisions in the energy sector has to be stressed. Europe will certainly not solve the climate problem on its own, but can help to deliver abatement technologies and to prove, that climate change can be reconciled with economic growth - provided a long-term framework is established that is in line with other goals like security of supply and affordable energy.(author).

    Climate models provide the opportunity to anticipate how the climate system may change due to anthropogenic activities during the 21. century. Studies are based on numerical simulations that explore the evolution of the mean climate and its variability according to different socio-economic scenarios. We present a selection of results from phase 5 of the Climate model intercomparison project (CMIP5) with an illustrative focus on the two French models that participated to this exercise. We describe the effects of human perturbations upon surface temperature, precipitation, the cryo-sphere, but also extreme weather events and the carbon cycle. Results show a number of robust features, on the amplitude and geographical patterns of the expected changes and on the processes at play in these changes. They also show the limitations of such a prospective exercise and persistent uncertainties on some key aspects. (authors)

    Social science literature shows that the topic of climate change is imbued with cultural meaning for most Americans, such that sound scientific information alone is likely to be unpersuasive to people already doubtful about climate change. A current educational program on climate change emphasizes the following: *Less reliance on geophysical data *Positive messages as frequently as possible *Making the subject personal and concrete *Focusing on scientific aspects of climate change while refraining from promotion of particular policy solutions *Seeking ways to speak to core identities of diverse audiences *Assuring that communication efforts on this highly divisive topic are based on sensitivity to, and respect for, the diversity of worldviews present in citizens *To the extent possible, emphasizing optimism as well as our personal and collective capability to solve the problem of climate change. While this may seem self-evident, we also remind ourselves of the importance of avoiding criticism, blame, demonization, or arrogance in building a more inclusive community of public leaders on climate literacy.; Citing the recognition of climate-change science by trusted organizations is probably more convincing than showing reams of geophysical data. In particular, citing the Department of Defense may speak to the values of many who remain skeptical. ; This image is intended to speak to people that deeply value passing on a way of life to their descendants. Although nationalism can be carried to an extreme, this imagery can convey the notion that protecting our world from climate change is actually patriotic, something few Americans may realize.

  10. Detection and Attribution of Climate Change : From global mean temperature change to climate extremes and high impact weather.

    CERN Multimedia

    CERN. Geneva

    2013-01-01

    This talk will describe how evidence has grown in recent years for a human influence on climate and explain how the Fifth Assessment Report of the Intergovernmental Panel on Climate Change concluded that it is extremely likely (>95% probability) that human influence on climate has been the dominant cause of the observed global-mean warming since the mid-20th century. The fingerprint of human activities has also been detected in warming of the ocean, in changes in the global water cycle, in reductions in snow and ice, and in changes in some climate extremes. The strengthening of evidence for the effects of human influence on climate extremes is in line with long-held basic understanding of the consequences of mean warming for temperature extremes and for atmospheric moisture. Despite such compelling evidence this does not mean that every instance of high impact weather can be attributed to anthropogenic climate change, because climate variability is often a major factor in many locations, especially for rain...

  11. Common Ground on Climate Change: Pairing Opposing Viewpoints for Conversations about Climate Change

    2017-12-01

    In American public discourse, people tend to strongly identify with the viewpoints held by their cultural and political tribes. However, entrenched positions do little to advance understanding, or work toward solving problems constructively. Worse yet, it has become commonplace to dismiss or demonize those coming from a different point of view - leading to the vitriolic stalemate that often characterizes social media and comment threads when it comes to climate change. One way to break this pattern is to invite people with opposing opinions to actually talk to one another. This presentation describes the lessons learned during the Common Ground on Climate Change project, in which people with contrasting views about climate change engage in a moderated interview with each other. Prior to the interview, participants complete a set of values-based questions. The goal is to reveal areas of common ground between apparent opposites, such as a sense of stewardship for Earth's resources, or an opinion that solutions to climate change will be more beneficial than harmful. The structure of the interviews is based on the hypothesis that if a conversation begins with an appreciation of common values, it becomes easier to broach areas of disagreement. Participants are matched up in one-on-one moderated interviews where they are encouraged to share their concerns, ideas, and priorities about the validity of climate science, the need for urgent action, and the types of solutions they find most tenable. Emerging themes from this series of interviews include the value of a diversity of outlooks, and the ability for moderated conversations to find surprising areas of agreement. Articles about the interviews also appear on the Yale Climate Connections website, https://www.yaleclimateconnections.org/author/karin/.

    Full Text Available Climate change adaptation is one of the most crucial issues in developing countries like Bangladesh. The main objective was to understand the linkage of participation with Community Based Adaptation (CBA to climate change. Institutional framework following different types of conceptual theories (collective action, group, game and social learning theory was utilized to analyze the participatory process in local community level Village Disaster Mangement Committee (VDMC that works in collaboration with local government. Field level data was collected through interview and group discussion during 25 April to 30 May 2015 in the Teesta riverine area of northern Bangladesh. Results showed that flood and drought were the major climate change impacts in the study area, and various participatory tools were used for risk assessment and undertaking action plans to overcome the climate change challenges by the group VDMC. Participation in VDMC generated both relational and technical outcomes. The relational outcomes are the informal institutional changes through which local community adopt technological adaptation measures. Although, limitations like bargaining problem, free riding or conflict were found in collective decision making, but the initiation of local governance like VDMC has brought various institutional change in the communities in terms of adaptation practices. More than 80% VDMC and around 40–55% non-VDMC household respondents agreed that overall community based adaptation process was successful in the previous year. They believed that some innovative practices had been brought in the community through VDMC action for climate change adaptation. No doubt that the CBA has achieved good progress to achieve the government Comprehensive Disaster Management (CDM strategy of climate change adaptation. But, there is still lack of coordination among local government, NGOs and civil partners in working together. Research related to socio

Additionally, the atlas will show the historical responsibility of the developed/developing countries and possible contributions to the mitigation of climate change according to their pledge of GHG emission reduction after the Cancun Agreement as an extension numerical experiment to CMIP5 with NCAR's CESM1.0. The authors will update this atlas after future releases of CMIP5 model outputs and update the figures in the second edition of the atlas in 2012-2013.

  14. Climate Change and Fish Availability

    Science.gov (United States)

    Teng, Paul P. S.; Lassa, Jonatan; Caballero-Anthony, Mely

    Human consumption of fish has been trending upwards in the past decades and this is projected to continue. The main sources of fish are from wild fisheries (marine and freshwater) and aquaculture. Climate change is anticipated to affect the availability of fish through its effect on these two sources as well as on supply chain processes such as storage, transport, processing and retail. Climate change is known to result in warmer and more acid oceans. Ocean acidification due to higher CO2 concentration levels at sea modifies the distribution of phytoplankton and zooplankton to affect wild, capture fisheries. Higher temperature causes warm-water coral reefs to respond with species replacement and bleaching, leading to coral cover loss and habitat loss. Global changes in climatic systems may also cause fish invasion, extinction and turnover. While this may be catastrophic for small scale fish farming in poor tropical communities, there are also potential effects on animal protein supply shifts at local and global scales with food security consequences. This paper discusses the potential impacts of climate change on fisheries and aquaculture in the Asian Pacific region, with special emphasis on Southeast Asia. The key question to be addressed is “What are the impacts of global climate change on global fish harvests and what does it mean to the availability of fish?”

    Global climate change and energy use are among the most relevant and pressing issues in today’s science curriculum, yet they are also complex topics to teach. The underlying science spans multiple disciplines and is quickly evolving. Moreover, a comprehensive treatment of climate change and energy use must also delve into perspectives not typically addressed in geosciences courses, such as public policy and economics. Thus, faculty attempting to address these timely issues face many challenges. To support faculty in teaching these subjects, the On the Cutting Edge faculty development program has created a series of websites and workshop opportunities to provide faculty with information and resources for teaching about climate and energy. A web-based collection of teaching materials was developed in conjunction with the On the Cutting Edge workshops “Teaching about Energy in Geoscience Courses: Current Research and Pedagogy.” The website is designed to provide faculty with examples, references and ideas for either incorporating energy topics into existing geoscience courses or for designing or refining a course about energy. The website contains a collection of over 30 classroom and lab activities contributed by faculty and covering such diverse topics as renewable energy, energy policy and energy conservation. Course descriptions and syllabi for energy courses address audiences ranging from introductory courses to advanced seminars. Other materials available on the website include a collection of visualizations and animations, a catalog of recommended books, presentations and related references from the teaching energy workshops, and ideas for novel approaches or new topics for teaching about energy in the geosciences. The Teaching Climate Change website hosts large collections of teaching materials spanning many different topics within climate change, climatology and meteorology. Classroom activities highlight diverse pedagogic approaches such as role

    Climate change is expected to exacerbate the current threats to freshwater ecosystems, yet multifaceted studies on the potential impacts of climate change on freshwater biodiversity at scales that inform management planning are lacking. The aim of this study was to fill this void through the development of a novel framework for assessing climate change vulnerability tailored to freshwater ecosystems. The three dimensions of climate change vulnerability are as follows: (i) exposure to climate change, (ii) sensitivity to altered environmental conditions and (iii) resilience potential. Our vulnerability framework includes 1685 freshwater species of plants, fishes, molluscs, odonates, amphibians, crayfish and turtles alongside key features within and between catchments, such as topography and connectivity. Several methodologies were used to combine these dimensions across a variety of future climate change models and scenarios. The resulting indices were overlaid to assess the vulnerability of European freshwater ecosystems at the catchment scale (18 783 catchments). The Balkan Lakes Ohrid and Prespa and Mediterranean islands emerge as most vulnerable to climate change. For the 2030s, we showed a consensus among the applied methods whereby up to 573 lake and river catchments are highly vulnerable to climate change. The anthropogenic disruption of hydrological habitat connectivity by dams is the major factor reducing climate change resilience. A gap analysis demonstrated that the current European protected area network covers climate change. Priority should be placed on enhancing stakeholder cooperation at the major basin scale towards preventing further degradation of freshwater ecosystems and maintaining connectivity among catchments. The catchments identified as most vulnerable to climate change provide preliminary targets for development of c
