    Climate change has a wide range of implications for the health, well-being, and economic prospects for Canadians, and for the ecological systems that sustain life on this planet. The overwhelming scientific opinion, world leaders and even a growing number of corporate leaders now agree that the Earth is undergoing a significant and unusual warming period as a result of the build-up of greenhouse gases in the atmosphere. There is also wide agreement that much of this build-up is anthropogenic, and that a global effort is required to slow this trend. Because climate change is a global problem, it requires global solutions by way of reduction in global greenhouse gas emissions. In this context, the Kyoto Agreement of 1997 constitutes a major breakthrough, even though it takes only a small step towards towards altering the human impact on global climate. Although some 80 states, plus the European Union signed the Kyoto Protocol, it remains unclear when it will come into force because the majority of states have failed to ratify it, pending the resolution of a variety of technical and operational details. Canada is the second highest emitter of greenhouse gases (16 tonnes per capita, compared to world average of 3.6 tonnes per capita). This, combined with Canada's foreign policy goals of playing a leading role in taking action and preserving its reputation as an honest broker, makes the challenge of meeting Canada's Kyoto commitments especially pressing. The purpose of this paper is to explain Canada's climate change policy in the context of these international and domestic pressures. The paper identifies the main climate change-related policy challenges, international responses to date and the constraints and opportunities open to Canada in the light of its economy, its federalist political structure, and place in the world as a middle power, as well as its geographic situation, natural resources and environmental endowment. There is a detailed discussion of the Kyoto

    Today there is much interest in teaching secondary students about climate change. Much of this effort has focused directly on students' understanding of climate change. We hypothesize, however, that in order for students to understand climate change they must first understand climate as a system and how changes to this system due to both natural…

    Issues related to climate change increasingly concern the functioning of local scale geo-systems. A global change will necessarily affect local climates. In this context, the potential impacts of climate change lead to numerous inter rogations concerning adaptation. Despite numerous studies on the impact of projected global warming on different regions global atmospheric models (GCM) are not adapted to local scales and, as a result, impacts at local scales are still approximate. Although real progress in meso-scale atmospheric modeling was realized over the past years, no operative model is in use yet to simulate climate at local scales (ten or so meters). (author)

    Full Text Available The paper examines emigration from Vietnam in the context of global climate change. Vietnam is among the five countries, most vulnerable to water level rise in the oceans associated with global warming. The areas of potential flooding include territories with most dense population and are extremity important for the economy of Vietnam. The country has a significant demographic potential exceeding 90 mln people. Vietnamese migration has a relatively long history. Large Vietnamese communities have grown in the countries of Eastern Europe; these communities are relatively well integrated into the host countries. Increase in global mean temperatures could lead to severe storms, tsunamis, and flooding and force significant portion of the population out of the Mekong Delta regions and Central provinces of Vietnam. The paper discusses the potential of Atlas Information Systems (AISs for the assessment of social-economic and demographic consequences of climate change in Vietnam. The authors describe an AIS they are developing. This AIS consists of blocks that provide for a close link between socio-political, economic (production, natural resource, and environmental components for the integrated assessment of the provinces of Vietnam. Simulation of events shows that the flood zone could affect such populated provinces as An Giang, Kien Giang, Hau Giang, Dong Thap, Long An, Tien Giang, Vinh Long and Can Tho. To address this problem, the Vietnamese authorities, in 2008, approved the state target program to respond to climate change. The Ministry of Natural Resources and Environment was commissioned to create a scenario of climate change and sea level rise in Vietnam. However, the problem requires an immediate response at the international level, as the threat cannot be localized within the borders of Vietnam. Flooding may require mandatory relocation of the population in the country and, possibly, beyond its borders. If people are not relocated gradually

    Global climate change and continued intensification of agriculture are two "mega-trends" that will impact agricultural systems in the coming decades. While often these two trends are analyzed in isolation, recent work describes how climate change has historically offset some crop yield gains that would have otherwise occurred. Here we spatially analyze how these interactions between climate change and agricultural development may continue to 2025. We highlight areas that will be hit hardest by climate change and require aggressive management changes, as well as areas where large productivity increases are likely given current trends. To carry out our analysis we rely on a recently developed climate analog model to produce projections of climate-induced yield changes, projections of business-as-usual crop yield trends utilizing time-series data from ~13,500 agricultural census units, and published estimates of possible crop yield increases from aggressive intervention to close yield gaps. We find that a rich picture of agriculture in 2025 emerges when analyzing these multiple critical drivers. In many regions, existing yield trends or more aggressive management interventions (closing yield gaps) can overcome negative impacts from climate change. Thus, intensification can provide a buffer from near-term climate impacts, but it is unclear how long society may be able to rely on this buffering capacity.

    Changes to sources, stressors, habitats, and geographic ranges; toxicological effects; end points; and uncertainty estimation require significant changes in the implementation of ecological risk assessment (ERA). Because of the lack of analog systems and circumstances in historically studied sites, there is a likelihood of type III error. As a first step, the authors propose a decision key to aid managers and risk assessors in determining when and to what extent climate change should be incorporated. Next, when global climate change is an important factor, the authors recommend seven critical changes to ERA. First, develop conceptual cause-effect diagrams that consider relevant management decisions as well as appropriate spatial and temporal scales to include both direct and indirect effects of climate change and the stressor of management interest. Second, develop assessment end points that are expressed as ecosystem services. Third, evaluate multiple stressors and nonlinear responses-include the chemicals and the stressors related to climate change. Fourth, estimate how climate change will affect or modify management options as the impacts become manifest. Fifth, consider the direction and rate of change relative to management objectives, recognizing that both positive and negative outcomes can occur. Sixth, determine the major drivers of uncertainty, estimating and bounding stochastic uncertainty spatially, temporally, and progressively. Seventh, plan for adaptive management to account for changing environmental conditions and consequent changes to ecosystem services. Good communication is essential for making risk-related information understandable and useful for managers and stakeholders to implement a successful risk-assessment and decision-making process.

    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.)

    Full Text Available Global warming and its origins triggered the beginning to considerable discussion in the last century. Studies of climate models presented in multidisciplinary scientific reports suggest that anthropogenic activities, particularly the emission of gases from the greenhouse effect, are greatly responsible for the current climate changes. The increase of carbon dioxide (CO2 atmospheric concentration has been in discussion in the news, scientific meetings and in public policy debates in several countries. Apart from its impact on global warming, the rising atmospheric CO2 has alerted the scientific community to the need to investigate any morpho-physiological alterations in the plants, given their direct influence on photosynthesis. This article aims to discuss cellular aspects related to plant growth, their behavior of cuticular waxes and the responses of the stomatal development arising from the chemical change to the atmosphere, which are the causes of serious concern and discussion.

    2014-01-01

    Since the laboratories of the IAEA Department of Nuclear Sciences and Applications were established in Seibersdorf in 1962, the world’s population has grown from 3.14 billion to 7.15 billion, which, combined with continuously increasing industrialization and economic development, has led to greater global food demand. This has placed substantial stress on natural resources as well as the agricultural production chain. The challenges to food safety and security have also been amplified by the impacts of climate change, which have global ramifications, as noted in the March 2014 report of the UN Intergovernmental Panel on Climate Change. Climate change impacts include higher temperatures, drought, more frequent extreme weather events and increased soil salinity which can have severe effects on agricultural production. Helping Member States adapt to and mitigate these impacts is a main focus of the five laboratories of the Joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture in Seibersdorf. These laboratories are dedicated to increasing food security and safety using nuclear science and technology

    The Dutch CO{sub 2} target - which was set down in the National Environmental Policy Plan Plus (NMP-plus) and sent to Parliament in 1990 - is to reduce emissions by 3 to 5 % in 2000 relative to 1989/1990. The second National Environmental Policy Plan (NMP-2), issued in December 1993, confirmed this target but also concluded that policies will have to be enhanced and additional measures taken in order to achieve it. The measures developed in NMP-plus assumed that real energy prices would rise substantially during the 1990`s. However, the prices are at their lowest level since the early 1970`s and official projections now assume that real energy prices will remain more or less constant between 1990 and 2000. Under these conditions, application of existing policy instruments will have to be intensified and additional policy instruments will have to be deployed in order to attain even the 3 % emission reduction target for CO{sub 2}. In December 1993 the Government`s second National Environmental Policy Plan and second Memorandum on Energy Conservation indicated how policy efforts in the area of climate change will be enhanced. Targets were set for improving energy efficiency in different sectors in the period 1989-2000: 23 % for households, 23 % for non-residential buildings, 19 % for industry, 26 % for agriculture, 10 % for transport and 26 % for power stations. The overall efficiency improvement (including renewables) will lead to energy consumption of 2865 PJ in 2000 (550 PJ less than what it would have been without the policy measures; slightly more than what it was in 1990). Energy efficiency (including renewables) will be responsible for roughly two thirds of the CO{sub 2} reduction needed, with the remainder coming from transport, recycling, reduced coal use, afforestation and structural changes

    This article (Chapter Two) focuses on the global nuclear markets in the context of policies regarding climate change and sustainable development. The global market realities and the export potential of the canadian nuclear industry are becoming crucial features of the nuclear political economy. The article examines the role of exports in the evolution of nuclear policy in Canada, and looks more closely at nuclear power and CANDU projects in the specific context of global competitive markets. It examines the trends in electricity and nuclear energy in the market for nuclear reactors. Finally, this article locates these changes in the context of the issues that are inherent in climate change and sustainable development

    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

    Full Text Available It is thought that direct personal experience of extreme weather events could result in greater public engagement and policy response to climate change. Based on this premise, we present a set of future climate scenarios for Ireland communicated in the context of recent, observed extremes. Specifically, we examine the changing likelihood of extreme seasonal conditions in the long-term observational record, and explore how frequently such extremes might occur in a changed Irish climate according to the latest model projections. Over the period (1900–2014 records suggest a greater than 50-fold increase in the likelihood of the warmest recorded summer (1995, whilst the likelihood of the wettest winter (1994/95 and driest summer (1995 has respectively doubled since 1850. The most severe end-of-century climate model projections suggest that summers as cool as 1995 may only occur once every ∼7 years, whilst winters as wet as 1994/95 and summers as dry as 1995 may increase by factors of ∼8 and ∼10 respectively. Contrary to previous research, we find no evidence for increased wintertime storminess as the Irish climate warms, but caution that this conclusion may be an artefact of the metric employed. It is hoped that framing future climate scenarios in the context of extremes from living memory will help communicate the scale of the challenge climate change presents, and in so doing bridge the gap between climate scientists and wider society.

    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...

    2010-05-28

    On palaeoclimate time scales, enhanced levels of geological and geomorphological activity have been linked to climatic factors, including examples of processes that are expected to be important in current and future anthropogenic climate change. Planetary warming leading to increased rainfall, ice-mass loss and rising sea levels is potentially relevant to geospheric responses in many geologically diverse regions. Anthropogenic climate change, therefore, has the potential to alter the risk of geological and geomorphological hazards through the twenty-first century and beyond. Here, we review climate change projections from both global and regional climate models in the context of geohazards. In assessing the potential for geospheric responses to climate change, it appears prudent to consider regional levels of warming of 2 degrees C above average pre-industrial temperature as being potentially unavoidable as an influence on processes requiring a human adaptation response within this century. At the other end of the scale when considering changes that could be avoided by reduction of emissions, scenarios of unmitigated warming exceeding 4 degrees C in the global average include much greater local warming in some regions. However, considerable further work is required to better understand the uncertainties associated with these projections, uncertainties inherent not only in the climate modelling but also in the linkages between climate change and geospheric responses.

    2011-07-01

    Full Text Available Climate change in the Canadian north is, and will be, managed by communities that are already experiencing social, political, economic and other environmental changes. Hence, there is a need to understand vulnerability to climate change in the context of multiple exposure-sensitivities at the community level. This article responds to this perceived knowledge need based on a case study of the community of Kugluktuk in Nunavut, Canada. An established approach for vulnerability assessment is used to identify current climatic and non-climatic exposure-sensitivities along with their associated contemporary adaptation strategies. This assessment of current vulnerability is used as a basis to consider Kugluktuk's possible vulnerability to climatic change in the future. Current climate-related exposure-sensitivities in Kugluktuk relate primarily to subsistence harvesting and community infrastructure. Thinner and less stable ice conditions and unpredictable weather patterns are making travel and harvesting more dangerous and some community infrastructure is sensitive to permafrost melt and extreme weather events (e.g., flash floods. The ability of individuals and households to adapt to these and other climatic exposure-sensitivities is influenced by non-climatic factors that condition adaptive capacity including substance abuse, the erosion of traditional knowledge and youth suicide. These and other non-climatic factors often underpin adaptive capacity to deal with and adapt to changing conditions and must be considered in an assessment of vulnerability. This research argues that Northern communities are challenged by multiple exposure-sensitivities—beyond just those posed by climate—and effective adaptation to climate change requires consideration if not resolution of socio-economic and other issues in communities.

    Full Text Available This research explored how transhumant pastoralism has been sustained and promoted in the context of socioeconomic and climate change in the mountain regions of Nepal. Based on case study research conducted in Nepal’s western mountains, the status, opportunities, and constraints of transhumant pastoralism in the changing context were analyzed. We found that indigenous and traditional knowledge, feelings of cultural identity, collective ownership, income, and mutual benefits have acted as motivating factors in sustaining transhumant pastoralism for generations. The continuation of this practice is threatened by the following challenges: the impacts of climate change on mountain ecosystems, socioeconomic changes, market influence on livelihood decisions, youth migration and labor shortage, low motivation of local people to engage in livestock rearing, and conflicts between herder and nonherder communities and institutions, as well as inadequate policy support and institutional arrangements. We conclude that unless there are positive policy and institutional arrangements to support transhumant pastoralism, the age-old practice will disappear.

    Climate change and its impact on gender in the context of Nepal has not been clearly understood due to lack of proper scientific research in terms of gender and climate change. Climate induced disasters such as droughts, floods, GLOFs, and landslides affect men and women differently. This study is conducted to analyze the scenario of gender equality, and impacts of climate change on gender in Nepal. This study also identifies gender based adaptation approaches through the use of observed climate data, and projected and modeled demographic data such as Adolescent Fertility Rate, Labor Force Participation Rate, and Maternal Mortality Ratio. The major tasks of this project include the calculation of Gender Inequality Index (GII), trend analysis and correlation between GII and temperature, that helps to evaluate the women vulnerability and identify the gender based adaptation interventions in Nepal. The required data on gender and temperature are obtained from World Bank and Department of Hydrology and Meteorology, Nepal. GII is calculated for almost 26 years starting from the year 1990 by utilizing a tool "Calculating the Indices using Excel" provided through the UNDP. The Reproductive Health Index (RHI), Empowerment Index (EI), and Labor Market Index (LMI) that are required to determine GII are also calculated through the use of same tool. The trend analysis shows that GII follows a decreasing trend indicating higher gender equality. The correlation analysis shows the temperature positively correlated with RHI (r=0.64), EI Female (r=0.61), and EI Male (r=0.73). In case of LMI, temperature is positively correlated with female (r=0.14) and negatively correlated with male (r=-0.57). The analysis depicts negative correlation (r=-0.68) between climate change and GII. This research will provide some valuable insights in the research relating to gender and climate change that could help gender advocates and policymakers in developing further plans for women empowerment.

    The inland navigation market of North-Western Europe faces potential problems due to climate change. Different measures may be taken by governments, carriers, and customers to cope with the negative effects of climate change. The effects of climate change on the inland navigation market may also be different for regions with different demand for transport by inland navigation. The research carried out in this dissertation can be seen as an investigation into adaptation strategies and the interaction-effects of imbalance and climate change on the inland navigation market. This gives rise to the following two main research questions for this dissertation: (1) What is the optimal barge-size adjustment for barge operators to cope with climate change, and what are the implications of climate change for investments in inland waterway infrastructure by the public sector?; (2) What is the impact of climate change on freight prices in the inland navigation market in the presence of direction dependent freight imbalances? There is still a gap in the scientific literature on the transport economic aspects of inland navigation in general. This dissertation contributes to this literature by approaching the field in a climate change context. In addition, the incorporation of imperfect information to the backhaul literature can be seen as a contribution to the economic theory. We show that imbalance leads to different impacts of climate change in different regions (even though the climate change may be the same for these regions). As a contribution to decision making, the adaptation strategies that are evaluated from a welfare economic perspective can be mentioned. Both private decision making (choice of barge size) and public decision making (choice of amount to invest in infrastructure) are supported, by providing the optimal values to be chosen for the instruments available. By taking the imbalance issue into account, this study gives insights into how to achieve a fair

    Over the past three years the Nebraska Earth Systems Education Network has designed professional development opportunities for K-12 and extension educators that integrates scientific content into the context of helping educators connect society with the complexities and consequences of climate change. Our professional development approach uses learner-, knowledge-, assessment-, and community-centered strategies to achieve our long-term goal: collaboration of scientists, educators and learners to foster civic literacy about climate change. Two NASA-funded projects, Global Climate Change Literacy for Educators (GCCE, 2009-2012), and the Educators Climatologists Learning Community (ECLC, 2011-2013), have provided the mechanism to provide teachers with scientifically sound and pedagogically relevant educational materials to improve climate and Earth systems literacy among educators. The primary product of the GCCE program is a 16-week, online, distance-delivered, asynchronous course entitled, Laboratory Earth: Human Dimensions of Climate Change. This course consists of four, four-week modules that integrate climate literacy, Earth Systems concepts, and pedagogy focused on active learning processes, building community, action research, and students' sense of place to promote action at the local level to address the challenges of climate change. Overall, the Community of Inquiry Survey (COI) indicated the course was effective in teaching content, developing a community of learners, and engaging students in experiences designed to develop content knowledge. A pre- and post- course Wilcoxan Signed Ranks Test indicated there was a statistically significant increase in participant's beliefs about their personal science teaching efficacy. Qualitative data from concept maps and content mastery assignments support a positive impact on teachers' content knowledge and classroom practice. Service Learning units seemed tohelp teachers connect course learning to their classroom

  5. Recent slope failures in the Dolomites (Northeastern Italian Alps) in a context of climate change

    Climate change in the Greater Alpine Region is seriously affecting permafrost distribution, with relevant consequences on slope stability. In the Italian Alps, the number of failures from rockwalls at high elevation markedly increased in the last 20-30 years: the consistent temperature increase, which warmed twice than the global average, may have seriously influenced slope stability, in terms of glaciers retreat and permafrost degradation. Moreover, the growing number of tourists and activities in alpine regions (in particular in the Dolomites) made these areas particularly critical in relation to natural hazards. In this light, an integrated short-term geomorphological and climatic analysis was performed, in order to better comprehend the impact of main climate elements (especially temperature and precipitation) on slope failures in high mountain areas. In this contribution, we focus on three recent slope failures occurred at high elevation sites in the Dolomites (Northeastern Italian Alps), declared a UNESCO World Heritage Site in August 2009. We describe here three important rock falls occurred in the autumn 2013: 1) the Sorapiss rock fall, on 30 September 2013; 2) the Monte Civetta rock fall, on 16 November 2013; 3) the Monte Antelao rock fall, on 22 November 2013. The Monte Civetta rock fall damaged some climbing routes, while the other two landslides did not cause any damage or injury. Despite the limited volume involved, these three events represent an important warning sign in the context of ongoing climate change. Geomorphological information about the rock fall sites were combined with the climatic data acquired from the meteorological stations surrounding the slope failure areas. A short-term climatic analysis was performed, with the aim of understanding the role of the main climatic elements in the triggering of natural instability events in this area and in the Alps in general.

    Infectious diseases are a major cause of morbidity and mortality in China. The capacity of hospitals to deal with the challenge from emerging and re-emerging infectious diseases due to climate change is of great importance to population health. This study aimed to explore the capacity of hospitals in China to deal with such challenges. A cross-sectional questionnaire survey was utilized to gauge information regarding capacity of hospitals to deal with infectious diseases in the context of climate change among 611 clinical professionals whose roles pertained to infectious disease diagnosis, treatment and management in Anhui Province of China. Descriptive analysis and logistic regression analysis were performed on the data. More than 90% of participants believed climate change would have an adverse influence on population health and infectious disease control in China. Most indicated that their hospitals were well prepared for emerging infectious diseases at present, and they considered that logistical support in hospitals (e.g. administrative and maintenance services) should be strengthened for future capacity building. The majority of participants suggested that effective prevention and control measures, more interdisciplinary collaborations, more funding in rural areas for health care, and improved access to facilities enabling online reporting of infectious diseases, were extremely important strategies in building capacity to curb the population health impact of emerging and re-emerging infectious diseases due to climate change in China. Clinical professionals recognized that climate change will likely increase the transmission of infectious diseases. Although rural health care and hospitals' logistical support need to be improved, most professionals believed their hospitals to be capable of dealing with emerging diseases. They thought that interdisciplinary and cross-regional collaborations, together with necessary resource support (e.g. improved facilities for

    Climate change has the potential to impair livestock health, with consequences for animal welfare, productivity, greenhouse gas emissions, and human livelihoods and health. Modelling has an important role in assessing the impacts of climate change on livestock systems and the efficacy of potential adaptation strategies, to support decision making for more efficient, resilient and sustainable production. However, a coherent set of challenges and research priorities for modelling livestock health and pathogens under climate change has not previously been available. To identify such challenges and priorities, researchers from across Europe were engaged in a horizon-scanning study, involving workshop and questionnaire based exercises and focussed literature reviews. Eighteen key challenges were identified and grouped into six categories based on subject-specific and capacity building requirements. Across a number of challenges, the need for inventories relating model types to different applications (e.g. the pathogen species, region, scale of focus and purpose to which they can be applied) was identified, in order to identify gaps in capability in relation to the impacts of climate change on animal health. The need for collaboration and learning across disciplines was highlighted in several challenges, e.g. to better understand and model complex ecological interactions between pathogens, vectors, wildlife hosts and livestock in the context of climate change. Collaboration between socio-economic and biophysical disciplines was seen as important for better engagement with stakeholders and for improved modelling of the costs and benefits of poor livestock health. The need for more comprehensive validation of empirical relationships, for harmonising terminology and measurements, and for building capacity for under-researched nations, systems and health problems indicated the importance of joined up approaches across nations.

    Full Text Available Species invasions threaten marine biodiversity globally. There is a concern that climate change is exacerbating this problem. Here, we examined some of the potential effects of warming water temperatures on the invasion of Western Atlantic habitats by a marine predator, the Indo-Pacific lionfish (Pterois volitans and P. miles. We focussed on two temperature-dependent aspects of lionfish life-history and behaviour: pelagic larval duration, because of its link to dispersal potential, and prey consumption rate, because it is an important determinant of the impacts of lionfish on native prey. Using models derived from fundamental metabolic theory, we predict that the length of time spent by lionfish in the plankton in early life should decrease with warming temperatures, with a concomitant reduction in potential dispersal distance. Although the uncertainty around change in dispersal distances is large, predicted reductions are, on average, more than an order of magnitude smaller than the current rate of range expansion of lionfish in the Caribbean. Nevertheless, because shorter pelagic larval duration has the potential to increase local retention of larvae, local lionfish management will become increasingly important under projected climate change. Increasing temperature is also expected to worsen the current imbalance between rates of prey consumption by lionfish and biomass production by their prey, leading to a heightened decline in native reef fish biomass. However, the magnitude of climate-induced decline is predicted to be minor compared to the effect of current rates of lionfish population increases (and hence overall prey consumption rates on invaded reefs. Placing the predicted effects of climate change in the current context thus reveals that, at least for the lionfish invasion, the threat is clear and present, rather than future [Current Zoology 58 (1: 1–8, 2012].

    The carbon and water intensity of US electricity generation has recently decreased due to the natural gas revolution and deployment of renewable technologies. Yet, power plants that require water for cooling still provide 80% of electricity generation and projected climate-water conditions may limit their power output and affect reliability. Understanding the connections and tradeoffs across water, electricity and climate systems is timely, as the nation tries to mitigate and adapt to a changing climate. Electricity expansion models are used to provide insight on power sector pathways given certain policy goals and economic conditions, but do not typically account for productivity limitations due to physical climate-water constraints. Here, we account for such constraints by coupling an electricity expansion model (Regional Energy Deployment System - ReEDS) with the combined Water Balance and Thermoelectric Power and Thermal Pollution Models (WBM-TP2M), which calculate the available capacity at power plants as a function of hydrologic flows, climate conditions, power plant technology and environmental regulations. To fully capture and incorporate climate-water impacts into ReEDS, a specific rule-set was designed for the temporal and spatial downscaling and up-scaling of ReEDS results into WBM-TP2M inputs and visa versa - required to achieve a modeling `loop' that will enable convergence on a feasible solution in the context of economic and geophysical constraints and opportunities. This novel modeling approach is the next phase of research for understanding electricity system vulnerabilities and adaptation measures using energy-water-climate modeling, which to-date has been limited by a focus on individual generators without analyzing power generation as a collective regional system. This study considers four energy policy/economic pathways under future climate-water resource conditions, designed under the National Energy Water System assessment framework. Results

    Since 2006, Electricite de France (EDF) applies a new hydro-climatological approach of extreme rainfall and flood predetermination - the SCHADEX method - for the design of dam spillways. In a context of potential increase of extreme event intensity and frequency due to climate change, the use of the SCHADEX method in non-stationary conditions is a main interest topic for EDF hydrologists. Thus, the scientific goal of this Ph.D. thesis work has been to evaluate the ability of the SCHADEX method to take into account future climate simulations for the estimation of future extreme floods. The recognized inabilities of climate models and down-scaling methods to simulate (extreme) rainfall distribution at the catchment-scale have been avoided, by developing and testing new methodological approaches. Moreover, the decomposition of the flood-producing factors proposed by the SCHADEX method has been used for considering different simulated climatic evolutions and for quantifying the relative impact of these factors on the extreme flood estimation. First, the SCHADEX method has been applied in present time over different climatic contexts (France, Austria, Canada and Norway), thanks to several colorations with academic and industrial partners. A sensitivity analysis allowed to quantify the extreme flood estimation sensitivity to rainfall hazard, catchment saturation hazard and rainfall-runoff transformation, independently. The results showed a large sensitivity of SCHADEX flood estimations to the rainfall hazard and to the rainfall-runoff transformation. Using the sensitivity analysis results, tests have been done in order to estimate the future evolution of 'key' variables previously identified. New climate model outputs (done within the CMIP5 project) have been analyzed and used for determining future frequency of rainfall events and future catchment saturation conditions. Considering these simulated evolutions within the SCHADEX method lead to a significant decrease of

    ) ensure environmental effectiveness, equity and historical responsibility. While it is clear that Annex I countries must continue to take the lead, a range of proposals are now on the table for what types of actions or commitments developing countries can take, with financial and technological support, in order to reduce emissions and achieve development goals simultaneously. The science of the land-use, land-use change and forestry (LULUCF) must play a guiding role when addressing greenhouse gas emissions from deforestation. It is quite clear that from both a climate and biodiversity perspective, reducing emissions from deforestation must be the top priority. The question is no longer if but how this should be done in a way that puts the world on track to stay below the critical threshold of 2 degrees C. Considering this perspective, the authors of this chapter welcome the new ideas and perspectives coming forth on this issue especially in the so-called compensation reductions proposal currently under discussion. Keeping the focus on reduction of emissions is crucial. Our contribution therefore, will only focus on emissions reductions from LULUCF and not move into the issues surrounding sequestration. The objective of this paper is to place the discussion of emissions reductions from deforestation in the context of the post-2012 regime and to raise the key issues that should be addressed in such discussions. It will therefore raise more questions that specific answers at this point in time.

    The Mediterranean Basin is expected to be more strongly affected by ongoing climate change than most other regions of the earth. The South-eastern France can be considered as case study for assessing global change impacts on forests. Based on non-parametric statistical tests, the climatic parameters (temperature, relative humidity, rainfall, global radiation) and forest-response indicators (crown defoliation, discoloration and visible foliar ozone injury) of two pine species (Pinus halepensis and Pinus cembra) were analyzed. In the last 20 years, the trend analyses reveal a clear hotter and drier climate along the coastline and slightly rainier inland. In the current climate change context, a reduction in ground-level ozone (O 3 ) was found at remote sites and the visible foliar O 3 injury decreased while deterioration of the crown conditions was observed likely due to a drier and warmer climate. Clearly, if such climatic and ecological changes are now being detected when the climate, in South-eastern France, has warmed in the last 20 years (+0.46–1.08 °C), it can be expected that many more impacts on tree species will occur in response to predicted temperature changes by 2100 (+1.95–4.59 °C). Climate change is projected to reduce the benefits of O 3 precursor emissions controls leading to a higher O 3 uptake. However, the drier and warmer climate should induce a soil drought leading to a lower O 3 uptake. These two effects, acting together in an opposite way, could mitigate the harmful impacts of O 3 on forests. The development of coordinated emission abatement strategies is useful to reduce both climate change and O 3 pollution. Climate change will create additional challenges for forest management with substantial socio-economic and biological diversity impacts. However, the development of future sustainable and adaptive forest management strategies has the potential to reduce the vulnerability of forest species to climate change. - Highlights: • We

    A review of Mexican energy and climate change policies was presented with reference to the implications for Mexico regarding energy supply, security and climate change policies. Mexico's development and energy indicators are considerably behind those of Canada and the United States, but its greenhouse gas emissions are also low in comparison. Mexican energy consumption and gross domestic product levels per capita are far below those of the United States and Canada. Although Mexico, a signatory of the United Nations Framework Convention on Climate Change and the Kyoto Protocol, is not obligated to commit itself to any target greenhouse gas emissions, it has implemented an active climate change policy that promotes energy efficiency, fuel substitution, development of alternative energy sources, forest conservation and reforestation, and climate change research. The author concluded that in addition to constitutional reform, a fully integrated North American energy market would need physical connections for electricity and natural gas. 4 figs

    Full Text Available Seaweed is an important aquaculture commodity that could contribute on climate change mitigation, related to its ability on absorbing CO2, as one of the green house gases, through photosynthesis. This study aimed to analyze seaweed potencies on carbon sequestration in the context of climate change mitigation while still resulting optimum production as primary purpose and to analyze the carrying capacity of Gerupuk Bay in order to manage sustainability of seaweed aquaculture. Seaweed, (Kappaphycus alvarezii was cultivated with long-line system in Gerupuk Bay, West Nusa Tenggara, during five months for three cultivation cycles. Samplings were conducted at days-15, 30, and 45 with CO2 absorption rates as main parameters. Water carrying capacity was calculated to determine the ability of Gerupuk Bay waters for supporting development of sustainable seaweed aquaculture. The results showed that absorption rates of CO2 by seaweed (K. alvarezii were different at each sampling days of cultivation periods; the highest value was at 10-20 days of cultivation. CO2 absorption analysis resulted based on sampling days of cultivation period could be appl ied to formulate the strategies for management of sustainable seaweed aquaculture, with optimal production and positively contributed to the environment. However, waters carrying capacity should also be considered as major aspect in the application of seaweed cultivation management, thus it can run continuously without causing conflicts with other interests.

  4. Analysis of magnitude and duration of floods and droughts in the context of climate change

    Research and scientific information are key elements of any decision-making process. There is also a strong need for tools to describe and compare in a concise way the regime of hydrological extreme events in the context of presumed climate change. To meet these demands, two complementary methods for estimating high and low-flow frequency characteristics are proposed. Both methods deal with duration and magnitude of extreme events. The first one "flow-duration-frequency" (known as QdF) has already been applied successfully to low-flow analysis, flood flows and rainfall intensity. The second one called "duration-flow-frequency" (DqF) was proposed by Strupczewski et al. in 2010 to flood frequency analysis. The two methods differ in the treatment of flow and duration. In the QdF method the duration (d-consecutive days) is a chosen fixed value and the frequency analysis concerns the annual or seasonal series of mean value of flows exceeded (in the case of floods) or non-exceeded (in the case of droughts) within d-day period. In the second method, DqF, the flows are treated as fixed thresholds and the duration of flows exceeding (floods) and non-exceeding (droughts) these thresholds are a subject of frequency analysis. The comparison of characteristics of floods and droughts in reference period and under future climate conditions for catchments studied within the CHIHE project is presented and a simple way to show the results to non-professionals and decision-makers is proposed. The work was undertaken within the project "Climate Change Impacts on Hydrological Extremes (CHIHE)", which is supported by the Norway-Poland Grants Program administered by the Norwegian Research Council.

    The repetition of droughts in France has led to a growing demand for irrigation water and consequently to an increase in requests for the construction of small farm dams. Although such dams are small, their accumulation in a basin affects river flows, because the water collected in these small farm dams is used for irrigation and thus does not contribute to river flow. In order to gain more insight into their impact on the annual and monthly discharges, especially during dry years, a small farm dam model was built and connected to a hydrometeorological model. Several scenarios with different volume capacities, filling catchment sizes and filling periods were tested for such dams. The results were analysed in a small basin in western France, where the pressure for building such dams is high, and then extended to the entire country. It was found that, due to the hydrometeorological conditions (mainly low precipitation compared to other regions in France), the development of small farm dams in north-western France would result in greater decreases in river flows and less efficient filling of small farm dams than in other regions. Therefore, such dams might not be as efficient as expected in supplying water to farmers when needed. Moreover, the ability to fill small farm dams is projected to decrease in a context of climate change, despite the uncertainty on the evolution of precipitation, thus worsening the situation.

    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

    The study of how long-term changes affect metacommunities is a relevant topic, that involves the evaluation of connections among biological assemblages across different spatio-temporal scales, in order to fully understand links between global changes and macroevolutionary patterns. We applied multivariate statistical analyses and diversity tests using a large data matrix of rodent fossil sites in order to analyse long-term faunal changes. Late Miocene rodent faunas from southwestern Europe were classified into metacommunities, presumably sharing ecological affinities, which followed temporal and environmental non-random assembly and disassembly patterns. Metacommunity dynamics of these faunas were driven by environmental changes associated with temperature variability, but there was also some influence from the aridity shifts described for this region during the late Miocene. Additionally, while variations in the structure of rodent assemblages were directly influenced by global climatic changes in the southern province, the northern sites showed a pattern of climatic influence mediated by diversity-dependent processes.

  12. Investigating the Capacity of Hydrological Models to Project Impacts of Climate Change in the Context of Water Allocation

    To analyse the impacts of climate changes, hydrological models are used to project the hydrology responds under future conditions that normally differ from those for which they were calibrated. The challenge is to assess the validity of the projected effects when there is not data to validate it. A framework for testing the ability of models to project climate change was proposed by Refsgaard et al., (2014). The authors recommend the use of the differential-split sample test (DSST) in order to build confidence in the model projections. The method follow three steps: 1. A small number of sub-periods are selected according to one climate characteristics, 2. The calibration - validation test is applied on these periods, 3. The validation performances are compered to evaluate whether they vary significantly when climatic characteristics differ between calibration and validation. DSST rely on the existing records of climate and hydrological variables; and performances are estimated based on indicators of error between observed and simulated variables. Other authors suggest that, since climate models are not able to reproduce single events but rather statistical properties describing the climate, this should be reflected when testing hydrological models. Thus, performance criteria such as RMSE should be replaced by for instance flow duration curves or other distribution functions. Using this type of performance criteria, Van Steenbergen and Willems, (2012) proposed a method to test the validity of hydrological models in a climate changing context. The method is based on the evaluation of peak flow increases due to different levels of rainfall increases. In contrast to DSST, this method use the projected climate variability and it is especially useful to compare different modelling tools. In the framework of a water allocation project for the region of Flanders (Belgium) we calibrated three hydrological models: NAM, PDM and VHM; for 67 gauged sub-catchments with approx

    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.

    Coastal embayments are at risk of impacts by climate change drivers such as ocean warming, sea level rise and alteration in precipitation regimes. The response of the ecosystem to these drivers is highly dependent on their magnitude of change, but also on physical characteristics such as bay morphology and river discharge, which play key roles in water residence time and hence estuarine functioning. These considerations are especially relevant for bivalve aquaculture sites, where the cultured biomass can alter ecosystem dynamics. The combination of climate change, physical and aquaculture drivers can result in synergistic/antagonistic and nonlinear processes. A spatially explicit model was constructed to explore effects of the physical environment (bay geomorphic type, freshwater inputs), climate change drivers (sea level, temperature, precipitation) and aquaculture (bivalve species, stock) on ecosystem functioning. A factorial design led to 336 scenarios (48 hydrodynamic × 7 management). Model outcomes suggest that the physical environment controls estuarine functioning given its influence on primary productivity (bottom-up control dominated by riverine nutrients) and horizontal advection with the open ocean (dominated by bay geomorphic type). The intensity of bivalve aquaculture ultimately determines the bivalve-phytoplankton trophic interaction, which can range from a bottom-up control triggered by ammonia excretion to a top-down control via feeding. Results also suggest that temperature is the strongest climate change driver due to its influence on the metabolism of poikilothermic organisms (e.g. zooplankton and bivalves), which ultimately causes a concomitant increase of top-down pressure on phytoplankton. Given the different thermal tolerance of cultured species, temperature is also critical to sort winners from losers, benefiting Crassostrea virginica over Mytilus edulis under the specific conditions tested in this numerical exercise. In general, it is

    Academic interest in strategies to reduce the impact of health services on climate change is quickening. Research has largely focused on local innovations with little consideration of the contextual and systemic elements that influence sustainable development across health systems. A realistic framework specifically to guide decision-making by health care providers is still needed. To address this deficit, the literature is explored in relation to health services and climate change mitigation strategies, and the contextual factors that influence efforts to mitigate climate effects in health service delivery environments are highlighted. A conceptual framework is proposed that offers a model for the pursuit of sustainable development practice in health services. A set of propositions is advanced to provide a systems approach to assist decision-making by decoding the challenges faced in implementing sustainable health services. This has important implications for health care providers, funders and legislators since the financial, policy and regulatory environment of health care, along with its leadership and models of care generally conflict with carbon literacy and climate change mitigation strategies. © The Author(s) 2016.

  20. Modeling global residential sector energy demand for heating and air conditioning in the context of climate change

    International Nuclear Information System (INIS)

    Isaac, Morna; Vuuren, Detlef P. van

    2009-01-01

    In this article, we assess the potential development of energy use for future residential heating and air conditioning in the context of climate change. In a reference scenario, global energy demand for heating is projected to increase until 2030 and then stabilize. In contrast, energy demand for air conditioning is projected to increase rapidly over the whole 2000-2100 period, mostly driven by income growth. The associated CO 2 emissions for both heating and cooling increase from 0.8 Gt C in 2000 to 2.2 Gt C in 2100, i.e. about 12% of total CO 2 emissions from energy use (the strongest increase occurs in Asia). The net effect of climate change on global energy use and emissions is relatively small as decreases in heating are compensated for by increases in cooling. However, impacts on heating and cooling individually are considerable in this scenario, with heating energy demand decreased by 34% worldwide by 2100 as a result of climate change, and air-conditioning energy demand increased by 72%. At the regional scale considerable impacts can be seen, particularly in South Asia, where energy demand for residential air conditioning could increase by around 50% due to climate change, compared with the situation without climate change

    Full Text Available In Sweden, where forests cover more than 60% of the land area, silviculture and the use of forest products by industry and society play crucial roles in the national carbon balance. A scientific challenge is to understand how different forest management and wood use strategies can best contribute to climate change mitigation benefits. This study uses a set of models to analyze the effects of different forest management and wood use strategies in Sweden on carbon dioxide emissions and removals through 2105. If the present Swedish forest use strategy is continued, the long-term climate change mitigation benefit will correspond to more than 60 million tons of avoided or reduced emissions of carbon dioxide annually, compared to a scenario with similar consumption patterns in society but where non-renewable products are used instead of forest-based products. On average about 470 kg of carbon dioxide emissions are avoided for each cubic meter of biomass harvested, after accounting for carbon stock changes, substitution effects and all emissions related to forest management and industrial processes. Due to Sweden’s large export share of forest-based products, the climate change mitigation effect of Swedish forestry is larger abroad than within the country. The study also shows that silvicultural methods to increase forest biomass production can further reduce net carbon dioxide emissions by an additional 40 million tons of per year. Forestry’s contribution to climate change mitigation could be significantly increased if management of the boreal forest were oriented towards increased biomass production and if more wood were used to substitute fossil fuels and energy-intensive materials.

    Coffee is one of the most important global crops and provides a livelihood to millions of people living in developing countries. Coffee species have been described as being highly sensitive to climate change, as largely deduced from modeling studies based on predictions of rising temperatures and changing rainfall patterns. Here, we discuss the physiological responses of the coffee tree in the context of present and ongoing climate changes, including drought, heat, and light stresses, and interactions between these factors. We also summarize recent insights on the physiological and agronomic performance of coffee at elevated atmospheric CO 2 concentrations and highlight the key role of CO 2 in mitigating the harmful effects of heat stress. Evidence is shown suggesting that warming, per se, may be less harmful to coffee suitability than previously estimated, at least under the conditions of an adequate water supply. Finally, we discuss several mitigation strategies to improve crop performance in a changing world.

    The global warming effect due to ?greenhouse gases? is a hot topic discussed by world climate scientists today. This effect causes sea levels to rise, countries experiencing extreme weather conditions, violent storms and long dry spells. In centuries to come, these catastrophic effects can cause the spread of diseases and destroy food production and human habitat. Over one-third of the greenhouse gases come from the burning of fossil fuel to generate electricity. Nuclear power plants do not generate these gases. This paper presents the results obtained from a case study using MESSAGE, an analytical tool developed by the IAEA, which was used to evaluate Malaysia future energy requirements and strategies in addressing climate change issues.

It began c. 7500 calBC, with early animal husbandry in the western Azov Sea area. The beginning of the second stage was connected with an arid climate (7000–6900 calBC and the origin of the Rakushechny Yar culture in the Lower Don region. The third stage (6500–6300 calBC occurred during a humid period. Besides animal husbandry, the steppe population borrowed the first pottery from the Rakushechny Yar culture. The fourth phase (6300–6000 calBC was connected with extreme aridity and the neolithisation of the modern forest-steppe and forest zones of Ukraine and Russia.

    The establishment of ecological public health as crucial to modern public health is overdue. While the basic concepts have been gestating for decades, receptivity within broader public health has been limited. This position is changing, not least as the population-level impacts of climate change and, more broadly, of limits to growth are emerging from theory and forecasting into daily reality. This paper describes several key elements of ecological public health thinking. These include the 'environmental' risks to human health (often systemic and disruptive, rather than local and toxic) posed by climate change and other forms of adverse global environmental change. Closer recognition of the links between social and environmental factors has been urged--an 'eco-social' approach--and, relatedly, for greater co-operation between social and natural sciences. The authors revisit critics of capitalism who foresaw the global capture and transformation of ecosystems for material human ends, and their resultant despoliation. The perennial call within public health to reduce vulnerability by lessening poverty is more important than ever, given the multifactored threat to the health of the poor which is anticipated, assuming no radical strategies to alleviate these pressures. But enhanced health security for the poor requires more than the reconfiguring of social determinants; it also requires, as the overarching frame, ecological public health.

    Energy demand depends on outdoor temperature in a 'u' shaped fashion. Various studies have used this temperature dependence to investigate the effects of climate change on energy demand. Such studies contain implicit or explicit assumptions to describe expected socio-economic changes that may affect future energy demand. This paper critically analyzes these implicit or explicit assumptions and their possible effect on the studies' outcomes. First we analyze the interaction between the socio-economic structure and the temperature dependence pattern (TDP) of energy demand. We find that socio-economic changes may alter the TDP in various ways. Next we investigate how current studies manage these dynamics in socio-economic structure. We find that many studies systematically misrepresent the possible effect of socio-economic changes on the TDP of energy demand. Finally, we assess the consequences of these misrepresentations in an energy demand model based on temperature dependence and climate scenarios. Our model results indicate that expected socio-economic dynamics generally lead to an underestimation of future energy demand in models that misrepresent such dynamics. We conclude that future energy demand models should improve the incorporation of socio-economic dynamics. We propose dynamically modeling several key parameters and using direct meteorological data instead of degree days. (author)

    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

    The plantation of forests has been recommended as one of the forms to prevent the effect greenhouse caused for the increase of the concentrations of determined gases in the terrestrial atmosphere. Climatic prevision have taken some organizations to consider behavior rules, with the purpose to minimize the emission of the greenhouse gases. The reduction of the greenhouse gases is one of the goals of the Kyoto Protocol. To make possible the implementation of its intentions, the Kyoto Protocol established commercial mechanisms, calls of 'flexibility mechanisms', amongst them, the Clean Development Mechanism - CDM. One of the lines of project considered eligible in the CDM is the called projects of carbon sequestration. This type of project, besides reducing CO{sub 2} of the atmosphere, contributes for the sustainable development, providing diverse useful goods and services to the man. Brazil will be able to assume a privileged position together to the countries that they search to revert the process of global climatic change, seating forest projects, edaphoclimatic conditions, availability of land, man power and the domain of technology are factors that contribute significantly for the attraction of investments of this nature.

    Occupational health is particularly affected by high heat exposures in workplaces, which will be an increasing problem as climate change progresses. People working in jobs of moderate or heavy work intensity in hot environments are at particular risk, owing to exposure to high environmental heat and internal heat production. This heat needs to be released to protect health, and such release is difficult or impossible at high temperatures and high air humidity. A range of clinical health effects can occur, and the heat-related physical exhaustion leads to a reduction of work capacity and labour productivity, which may cause substantial economic losses. Current trends in countries of the World Health Organization South-East Asia Region are towards higher ambient heat levels during large parts of each year, and modelling indicates continuing trends, which will particularly affect low-income individuals and communities. Prevention activities need to address the climate policies of each country, and to apply currently available heat-reducing technologies in workplaces whenever possible. Work activities can be adjusted to reduce exposure to daily heat peaks or seasonal heat concerns. Application of basic occupational health principles, such as supply of drinking water, enforcement of rest periods and training of workers and supervisors, is essential.

    Full Text Available The key challenge for individuals, businesses and governments would be the building financial and insurance resilience in changing climate. It becomes important issue for the financial management to create financial protection and insurance means to manage the financial losses, reducing the economic impact of disaster events, and supporting better recovery. In accordance with that the Paper provides an overview of the field and desk research of potential income implications of climate change for the financial management of disaster risks and losses. Desk research is based on Serbian case and its experience with the 2014 floods. Key findings of the field research provided in Serbia in 2016 on managing the risk of natural disasters, floods, fires, earthquakes as a part of organizational risk in 92 manufacturing firms, banks and insurance companies is also provided in the Paper. The methods used are: statistical description, X2 test and liner regression models. The results of both researches on risk management of floods showed that: companies calculate the impact of this risk to their year revenues as small, also a non-strategic approach of the Serbian government can be seen, as a financial gap of 65% in covering the losses. The research results pointed also to low awareness of the problem on the corporate and national level. The contribution of the Paper is to support further development of country and local plans for more effectively reducing the economic disruption of disaster events and policy approaches to supporting the penetration of disaster finance and insurance coverage and the capacity of insurance markets to absorb these risks. Also, to support the improvement of the culture of risk management of business sector in this field.

    The dispersal of the genus Homo occurred against a background of continuous environmental change. Here, dispersals of large mammals through the Levantine Corridor and into Western Europe and Java are studied and compared to existing records of climatic change and dispersals of early humans and lithic industry. The first human dispersal (with Oldowan lithic industry) out of Africa, around or shortly before 1.8 Ma may have been triggered by biological evolution and increased social organisation, rather than environmental change. After that event, increasing aridity led to decreased faunal exchange between Africa and Eurasia and may have isolated the human populations of Africa and Africa. Southern (Java) and Eastern Asia (China) also seem to have been isolated. Human dispersal into Western Europe may have been limited by closed environments in Central Europe until about 1.2 Ma ago, when faunal dispersal into Europe suggests the cyclic spread of open environments to the west. Acheulean technology originated in Africa, some 1.6-1.5 Ma ago, but its dispersal into Eurasia may have been obstructed by an arid Southwest Asia, until broadly about 0.9 Ma ago, when faunal exchange suggests that the area became temporarily less dry. By 0.6-0.5 Ma ago it reached Europe.

    Water erosion is one of the main environmental problems in Peru. The elevated rates of soil erosion are related to the rough topography of the Andes, shallow soils, highly erosive climate and the inappropriate land use management. Agricultural activities are directly affected by the elevated soil erosion rates, either through reduced crop production and/or damage to irrigation infrastructure. Similarly, the development of water infrastructure and hydropower facilities can be negatively affected by high sedimentation rates. However, critical information about sediment production, transport and deposition is still mostly lacking. This paper focuses on sediment dynamics in the context of land use and climate change in the Peruvian Andes. Within the Peruvian Coastal Range, the catchment of the Cañete River is studied as it plays an important role in the social and economic development of the region, and due to its provision of water and energy to rural and urban areas. The lower part of the basin is an arid desert, the middle sub-humid part sustains subsistence agriculture, and the upper part of the basin is a treeless high-elevation puna landscape. Snow cover and glaciers are present at its headwaters located above 5000 m asl. The retreat of glaciers due to climate change is expected to have an impact on water availability, and the production and mobilization of sediment within the river channels. Likewise, climate variability and land cover changes might trigger an important increase of erosion and sediment transport rates. The methodology applied to face this issue is principally based on the analysis of sediment samples recollected in the basin in the period 1998 to 2001, and the application of a water and sediment routing model. The paper presents new data on the sensitivity of water infrastructure and hydropower facilities to climate-induced changes in sediment mobilization.

    Full Text Available Global climate change mitigation and CO2 emission reduction have promoted the revolutionary transformation in energy system. The core content of energy system revolutionary transformation is to replace the high-carbon energy system dominated by fossil energy with low-carbon energy system dominated by new and renewable energy and finally realize the near-zero emission of CO2. The new energy system transformation has also led to a reform in global economic and social development patterns. Developing low-carbon economy becomes the fundamental strategy of sustainable development under climate risk management and the only solution to getting on the road from industrial civilization to ecological civilization. China intends to achieve the peaking of CO2 emissions around 2030 and increase the share of non-fossil fuels in primary energy consumption to around 20% by 2030. Guided by the targets, China directs its economy development to a low-carbon pattern. Therefore, new and renewable power capacity need to reach 1300 GW, and the electricity generated should be 4 times of that in 2013 with a continuous increase rate of 6%–8% around 2030. The pace of energy substitution need to be accelerated and efficient, safe, clean, and low-carbon energy supply and consumption systems should be established besides strengthened energy conservation and improved energy efficient. Therefore, reform need be deepened, favorable policy system and market mechanism for energy revolution and low-carbon development need be established, energy pricing mechanism should be reformed, and national carbon market should be formed to provide a favorable policy and market environment for low-carbon technology innovation and industry development.

  19. Impact of Climate Conditions on Occupational Health and Related Economic Losses: A New Feature of Global and Urban Health in the Context of Climate Change.

    One feature of climate change is the increasing heat exposure in many workplaces where efficient cooling systems cannot be applied. Excessive heat exposure is a particular problem for working people because of the internal heat production when muscle work is carried out. The physiological basis for severe heat stroke, other clinical effects, and heat exhaustion is well known. One feature of this health effect of excessive workplace heat exposure is reduced work capacity, and new research has started to quantify this effect in the context of climate change. Current climate conditions in tropical and subtropical parts of the world are already so hot during the hot seasons that occupational health effects occur and work capacity for many working people is affected. The Hothaps-Soft database and software andClimateCHIP.orgwebsite make it possible to rapidly produce estimates of local heat conditions and trends. The results can be mapped to depict the spatial distribution of workplace heat stress. In South-East Asia as much as 15% to 20% of annual work hours may already be lost in heat-exposed jobs, and this may double by 2050 as global climate change progresses. By combining heat exposure data and estimates of the economic consequences, the vulnerability of many low- and middle-income countries is evident. The annual cost of reduced labor productivity at country level already in 2030 can be several percent of GDP, which means billions of US dollars even for medium-size countries. The results provide new arguments for effective climate change adaptation and mitigation policies and preventive actions in all countries. © 2015 APJPH.

  20. Holocene climate and environmental change in the Palliser Triangle: a geoscientific context for evaluating the impacts of climate change on the southern Canadian prairies

    1999-07-01

    The Palliser Triangle is the driest portion of the Canadian Prairies, and one of the most climatically sensitive regions in Canada. As proof of that, it has suffered severe droughts in the 1920s, 1930s and the 1980s. General climatic models predict that future global warming will be most pronounced in northern regions and continental interiors, including the Great Plains of North America. Evidence of warming is already present in the regional climate record, suggesting that the Palliser Triangle is likely to become even more arid, and drought frequency may increase. This volume contains 18 papers related to major objectives of a project involving the use of the unique paleoenvironmental records available in the Palliser Triangle to assess the impacts of future climate change. Two major objectives of the project are of particular focus: the reconstruction of the Holocene (post-glacial) climatic and hydrological changes, and the evaluation of the relationship between climate and landscape processes. Each paper is capable of standing on its own as a contribution to a specific geoscience discipline; by bringing them together in one regionally focused volume, the editors intend to highlight the need for interdisciplinary and multidisciplinary approaches to the study of global climate change issues. The first paper provides a broad summary of the major results, followed by nine papers devoted to records of past climate and hydrological change documented in paleolimnological and hydrogeological studies. The remaining eight papers focus on geomorphic processes in the Palliser Triangle, and on explanations of how these processes respond to climate forcing. Since each contribution can stand its own, each paper has its own abstract in English and French and its own bibliography. There is an author index for the volume as whole.

    Cyanobacteria are a growing concern in the province of Quebec due to recent highly publicised bloom episodes. The health risk associated with the consumption of drinking water coming from contaminated sources was unknown. A study was undertaken to evaluate treatment plants' capacity to treat cyanotoxins below the maximum recommended concentrations of 1.5 microg/L microcystin-LR (MC-LR) and the provisional concentration of 3.7 microg/L anatoxin-a, respectively. The results showed that close to 80% of the water treatment plants are presently able to treat the maximum historical concentration measured in Quebec (5.35 microg/L MC-LR equ.). An increase, due to climate change or other factors, would not represent a serious threat because chlorine, the most popular disinfectant, is effective in treating MC-LR under standard disinfection conditions. The highest concentration of anatoxin-a (2.3 microg/L) measured in natural water thus far in source water is below the current guideline for treated waters. However, higher concentrations of anatoxin-a would represent a significant challenge for the water industry as chlorine is not an efficient treatment option. The use of ozone, potassium permanganate or powder activated carbon would have to be considered.

    Climate change has been stated as being one of the greatest challenges to global health in the current century. Climate change impacts on human health and the socio-economic and related poverty consequences are however still poorly understood. While epidemiological issues are strongly coupled with environmental and climatic parameters, the social and economic circumstances of populations might be of equal or even greater importance when trying to identify vulnerable populations and design appropriate and well-targeted adaptation measures. The inter-linkage between climate change, human health risk and socio-economic impacts remains an important - but largely outstanding - research field. We present an overview on how risk is traditionally being conceptualised in the human health domain and reflect critically on integrated approaches as being currently used in the climate change context. The presentation will also review existing approaches, and how they can be integrated towards adaptation tools. Following this review, an integrated risk concept is being presented, which has been currently adapted under the EC FP7 research project (HEALTHY FUTURES; http://www.healthyfutures.eu/). In this approach, health risk is not only defined through the disease itself (as hazard) but also by the inherent vulnerability of the system, population or region under study. It is in fact the interaction of environment and society that leads to the development of diseases and the subsequent risk of being negatively affected by it. In this conceptual framework vulnerability is being attributed to domains of lack of resilience as well as underlying preconditions determining susceptibilities. To fulfil a holistic picture vulnerability can be associated to social, economic, environmental, institutional, cultural and physical dimensions. The proposed framework also establishes the important nexus to adaptation and how different measures can be related to avoid disease outbreaks, reduce

    This paper was the major one of the opening plenary session at the Climate Change 2 conference. The paper provides a context for assessing the needs for technologies to reduce the concentration of GHG in the atmosphere. It looks at sources, sinks and trends for GHG, in the world at large and in Canada, and at efforts to develop new technologies to achieve the goals of climate change policy. The paper focusses on transport, electricity and biomass as sectors of interest, both because of their potential for contributing to climate change policy goals within Canada, and also because of research interests

    Especially coastal areas are vulnerable in case of sea level rise and changing climate conditions. Therefore, the NAWAK study (design of sustainable adaptation strategies for infrastructures in water management under the conditions of climatic and demographic change) started in 2013. It is designed to assess impairments of groundwater availability for a coastal lowland aquifer system in North-West Germany (> 1.000 km2) in the context of climate and socio-economic changes. The research results are focused on the quantification of the groundwater availability for past and future scenarios. Impacts from both climatic and socio-economic changes on the water availability and water balance are assessed by means of hydrologic, hydrogeological and geophysical models and methods, which where developed and adapted by project partners. For the model area there are three fields of work to create the conditions for a density dependent calculation of changings in salt-freshwater budget with the numerical model d3f++ (distributed density-driven Flow). The first is the description of initial conditions in three dimensions, especially for the salt-freshwater boundary. That description is based on airborne electromagnetic data of the underground and a complex processing to identify the differences between salt and freshwater, without anthropogenic and geologic influences. A validation is possible by comparison with groundwater measurements and an online monitoring of specific conductivity. The second is the calculation and measurement of flow conditions to derive the boundary conditions and the groundwater recharge. The groundwater recharge was calculated by using the hydrologic model PANTA RHEI. It is a conceptual model with partly physic-based modules, especially for the soil water processes. The model was calibrated and validated by discharge measurements and groundwater levels. The third step is a detailed information about the spatial discretization and the reconstruction of

    Global warming will unquestionably increase the impact of heat on individuals who work in already hot workplaces in hot climate areas. The increasing prevalence of this environmental health risk requires the improvement of assessment methods linked to meteorological data. Such new methods will help to reveal the size of the problem and design appropriate interventions at individual, workplace and societal level. The evaluation of occupational heat stress requires measurement of four thermal climate factors (air temperature, humidity, air velocity and heat radiation); available weather station data may serve this purpose. However, the use of meteorological data for occupational heat stress assessment is limited because weather stations do not traditionally and directly measure some important climate factors, e.g. solar radiation. In addition, local workplace environmental conditions such as local heat sources, metabolic heat production within the human body, and clothing properties, all affect the exchange of heat between the body and the environment. A robust occupational heat stress index should properly address all these factors. This article reviews and highlights a number of selected heat stress indices, indicating their advantages and disadvantages in relation to meteorological data, local workplace environments, body heat production and the use of protective clothing. These heat stress and heat strain indices include Wet Bulb Globe Temperature, Discomfort Index, Predicted Heat Strain index, and Universal Thermal Climate Index. In some cases, individuals may be monitored for heat strain through physiological measurements and medical supervision prior to and during exposure. Relevant protective and preventive strategies for alleviating heat strain are also reviewed and proposed.

    This paper examines the health implications of global PM reduction accompanying greenhouse gas emissions reductions in the 180 national economies of the global macroeconomy. A human health effects module based on empirical data on GHG emissions, PM emissions, background PM concentrations, source apportionment and human health risk coefficients is used to estimate reductions in morbidity and mortality from PM exposures globally as co-reduction of GHG reductions. These results are compared against the "fuzzy bright line" that often underlies regulatory decisions for environmental toxics, and demonstrate that the risk reduction through PM reduction would usually be considered justified in traditional risk-based decisions for environmental toxics. It is shown that this risk reduction can be on the order of more than 4 × 10(-3) excess lifetime mortality risk, with global annual cost savings of slightly more than $10B, when uniform GHG reduction measures across all sectors of the economy form the basis for climate policy ($2.2B if only Annex I nations reduce). Consideration of co-reduction of PM-10 within a climate policy framework harmonized with other environmental policies can therefore be an effective driver of climate policy. An error analysis comparing results of the current model against those of significantly more spatially resolved models at city and national scales indicates errors caused by the low spatial resolution of the global model used here may be on the order of a factor of 2.

    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 adaptation and transition to new configurations of energy systems brought on by challenges of climate change, energy security, and sustainability have encouraged more integrative approaches that bring together the social and technical dimensions of technology. The perspectives of energy systems and climate change play an important role in the development and implementation of emerging energy technologies and attendant policies on greenhouse gas reduction. This research examines citizens’ views on climate change and a number of energy systems, with a specific focus on the use of carbon capture and storage (CCS) as a technology to address greenhouse gas emissions. An all-day workshop with 82 local participants was held in the city of Calgary in Alberta, Canada to explore the views of climate change, energy and CCS. Participants were provided the opportunity to ask experts questions and discuss in small groups their views of climate change policy and energy systems. Results demonstrate that participants’ assessments of energy systems are influenced by social–political–institutional–economic contexts such as trust in industry and government, perception of parties benefiting from the technology, and tradeoffs between energy systems. We discuss our findings in the context of understanding social learning processes as part of socio-technical systems change. - Highlight: ► Energy systems are judged in the context of wider socio-technical system dimensions. ► Skepticism about climate change may affect support for CCS. ► Concerns about CCS include: CO 2 leaks, accuracy of monitoring and costs.

    Hope has the potential to be a powerful motivator for influencing behavior. However, hope and messages that evoke hope (hope appeals) have rarely been the focus of theoretical development or empirical research. As a step toward the effective development and use of hope appeals in persuasive communication, this study conceptualized and operationalized hope appeals in the context of climate change prevention. Then, the study manipulated components of the hope evocation part of a hope appeal. Specifically, the components were designed to address appraisals of the importance, goal congruence, future expectation, and possibility of climate protection, resulting in a 2 (strong/weak importance) × 2 (strong/weak goal congruence) × 2 (strong/weak future expectation) × 2 (strong/weak possibility) between-subjects pretest-posttest factorial design. Two hundred forty-five undergraduate students were randomly assigned to one of the 16 message conditions and completed the study online. The study tested whether the four appraisals predict feelings of hope. It determined whether message components that address importance, goal congruence, future expectation, and possibility affect appraisals, feelings of hope, and persuasion outcomes. Finally, this study tested the effects of feelings of hope on persuasion outcomes. This study takes an important step toward enabling the effective use of hope appeals in persuasive communication.

    The findings of the project ''Strengthening of approaches and instruments as well as promotion of processes to reduce the security risks posed by climate change in the context of climate change adaptation'' are summarized in this report. The main objective of the project is to outline the potential contribution of adaptation measures to avoid crisis and conflicts caused or exacerbated by water scarcity, food shortages or extreme weather events. As discussed in the conceptual chapter of the report, adaptation can contribute to peace and stability even in conflict-prone areas given that a conflict-sensitive approach is applied. On the basis of a comprehensive regional analysis, we show that adaptation is not yet a prominent element of regional cooperation. To address this gap, we design three regional adaptation roadmaps for the Andes region, Central and South Asia based on desk review of regional processes and programs as well as expert consultations. To ensure that the results of the projects can be considered in national and international policy processes and to strengthen international governance for adaptation we close with a Memorandum for action outlining major principles to support processes for adaptation and peace.

    Full Text Available Social systems in mountain regions are exposed to a number of disturbances, such as climate change. Calls for conceptual and practical approaches on how to address climate change have been taken up in the literature. The resilience concept as a comprehensive theory-driven approach to address climate change has only recently increased in importance. Limited research has been undertaken concerning tourism and resilience from a network governance point of view. We analyze tourism supply chain networks with regard to resilience to climate change at the municipal governance scale of three Alpine villages. We compare these with a planned destination management organization (DMO as a governance entity of the same three municipalities on the regional scale. Network measures are analyzed via a quantitative social network analysis (SNA focusing on resilience from a tourism governance point of view. Results indicate higher resilience of the regional DMO because of a more flexible and diverse governance structure, more centralized steering of fast collective action, and improved innovative capacity, because of higher modularity and better core-periphery integration. Interpretations of quantitative results have been qualitatively validated by interviews and a workshop. We conclude that adaptation of tourism-dependent municipalities to gradual climate change should be dealt with at a regional governance scale and adaptation to sudden changes at a municipal scale. Overall, DMO building at a regional scale may enhance the resilience of tourism destinations, if the municipalities are well integrated.

    This paper provides a context for assessing the needs for technologies to reduce the concentration of GHG in the atmosphere. It looks at sources, sinks and trends for GHG, in the world at large and in Canada, and at efforts to develop new technologies to achieve the goals of climate change policy. Technology development is one of many approaches to reducing emissions and absorbing GHG from the atmosphere. New technologies will be more successful if they can also achieve non-climate goals, such as better air quality or reduced soil erosion. This paper examines sectors where new technology may be most needed. In general these will be areas where emissions are large, or growing rapidly, or both. It focuses on transport, electricity and biomass as sectors of interest, both because of their potential for contributing to climate change policy goals within Canada, and also because of the author's own research interests.

    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

    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.

    Full Text Available This study extends the emerging body of research on farmer adaptation to climate change, by segmenting farmers on the basis of specific attributes (health, values, belief about climate change, sense of responsibility for climate change, desire to change, social, human and financial capitals and farmer demographics and considering such attributes as critical social aspects of the contextualized capacity to adapt. The segmental analysis was based on a nationally representative sample of 3,993 farmers concerned with farmer adaptation of climate risks. The resulting data were subjected to two-step cluster analysis to identify homogenous groups of farmers based on factors related to climate change adaptation. A three-cluster solution was identified wherein farmers were distinguishable on the basis of belief in climate change, desire for financial assistance and advice, social connectedness, information seeking, and adverse farm conditions. The largest group (Cluster 1: 55% was characterized by farmers who recognized being affected by drought and drying and who were actively engaged in adaptive practices, despite the fact that they had little income and poor farm resources. One third of these farmers reported that their health was a barrier to sustained activity in farming. Cluster 2 (26% was characterized by farmers not readily affected by drying, who enjoyed good incomes, good health and better farming conditions. They expressed little desire to adapt. The smallest cluster (Cluster 3: 19% was also characterized by farmers who recognized that they were affected by drying. However, despite a desire to adapt, they had very little means to do so. They reported the poorest natural resources and the poorest health, despite being younger. The findings suggest that it is the intent to adapt, starting from where people are at, which is a more important indicator of the capacity to work towards sustainable practices than assets tests alone.

    Social vulnerability assessment remains central in discourses on global climatic change and takes a more pertinent meaning considering that natural disasters in African countries continue to deeply affect human settlements and destroys human livelihoods. In recent years, in particular large territories and growing cities have experienced severe weather events. Among them are river and flash floods, affecting the social and economic assets of local populations. The impact of the damage related to floods is not only perceptible during seasonal events but also during unexpected larger disasters which place a particular burden on local population and institutions to adapt effectively to increasing climatic pressures. Important features for social vulnerability assessment are the increasing severity of the physical damages, the shortcoming of social and technical infrastructure, the complexity of land management/market, the limited capacity of local institutions and last but not least the restricted capacities of local population to resist these events. Understanding vulnerability implies highlighting and interlinking relevant indicators and/or perceptions encompassed in four main dimensions: social, institutional, physical and attitudinal vulnerability. Case studies in Dar es Salaam, Ouagadougou and Addis Ababa were carried out to obtain insights into the context-related conditions, behavior routines and survival networks in urban areas in west and east Africa. Using a combination of tools (e.g. focus group discussions, transect walks, interviews) we investigated in close cooperation with African partners how households and communities are being prepared to cope with, as well as to recover from floods. A comprehensive process of dealing with floods can be described based on sequential attributes concerning i) Anticipation before a flood occurs, ii) Resistance and coping activities during a flood event and, iii) Recovery and reconstruction afterwards.

    A worldwide increase in tree decline and mortality has been linked to climate change and, where these represent foundation species, this can have important implications for ecosystem functions. This study tests a combined approach of phylogeographic analysis and species distribution modelling to provide a climate change context for an observed decline in crown health and an increase in mortality in Eucalyptus wandoo, an endemic tree of south-western Australia. Phylogeographic analyses were undertaken using restriction fragment length polymorphism analysis of chloroplast DNA in 26 populations across the species distribution. Parsimony analysis of haplotype relationships was conducted, a haplotype network was prepared, and haplotype and nucleotide diversity were calculated. Species distribution modelling was undertaken using Maxent models based on extant species occurrences and projected to climate models of the last glacial maximum (LGM). A structured pattern of diversity was identified, with the presence of two groups that followed a climatic gradient from mesic to semi-arid regions. Most populations were represented by a single haplotype, but many haplotypes were shared among populations, with some having widespread distributions. A putative refugial area with high haplotype diversity was identified at the centre of the species distribution. Species distribution modelling showed high climatic suitability at the LGM and high climatic stability in the central region where higher genetic diversity was found, and low suitability elsewhere, consistent with a pattern of range contraction. Combination of phylogeography and paleo-distribution modelling can provide an evolutionary context for climate-driven tree decline, as both can be used to cross-validate evidence for refugia and contraction under harsh climatic conditions. This approach identified a central refugial area in the test species E. wandoo, with more recent expansion into peripheral areas from where it had

    Many US forest managers have used historical ecology information to assist in the development of desired conditions. While there are many important lessons to learn from the past, we believe that we cannot rely on past forest conditions to provide us with blueprints for future management. To respond to this uncertainty, managers will be challenged to integrate adaptation strategies into plans in response to changing climates. Adaptive strategies include resistance options, resilience options, response options, and realignment options. Our objectives are to present ideas that could be useful in developing plans under changing climates that could be applicable to forests with Mediterranean climates. We believe that managing for species persistence at the broad ecoregion scale is the most appropriate goal when considering the effects of changing climates. Such a goal relaxes expectations that current species ranges will remain constant, or that population abundances, distribution, species compositions and dominances should remain stable. Allowing fundamental ecosystem processes to operate within forested landscapes will be critical. Management and political institutions will have to acknowledge and embrace uncertainty in the future since we are moving into a time period with few analogs and inevitably, there will be surprises.

    The 'Adaptation in Europe' report describes the policies and some of the measures taken at EU level and by European countries. So far half of the 32 EEA member countries have plans for adaptation, and some have started to take action, although all countries still have a lot of work to do. While global mitigation efforts should continue to aim to limit global temperature increases to 2 deg. C, the report states that it is necessary to prepare for a greater range of temperature increases and other climate changes. This is needed to properly account for the many uncertainties in climatic and socio-economic projections. The report recommends a combination of different measures - 'grey' measures such as technological and engineering projects, 'green' ecosystem-based approaches using nature, and so-called 'soft' measures such as policies to change governance approaches. The most effective adaptation projects often combine two or more different approaches, the report says. For example, adaptation on France's Mediterranean coast uses an integrated approach considering climate change, tourism, transport and biodiversity. In urban areas green spaces and water bodies work together with building design to reduce heatwave risks. Barcelona has also started to adapt to water shortages with a new highly efficient desalination plant. This 'grey' project works in tandem with other 'soft' initiatives such as incentives to reduce water consumption, reducing the impacts from prolonged droughts. While the cost of adaptation may be high in some cases, the report emphasises the overall savings from some adaptation actions. One of the largest ecosystem-based adaptation projects is restoring the Danube river basin to its previously natural state.

    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

    2013-04-01

    The evidence of the impact of the anthropogenic activity over the climate change, as well as the consequent impacts in temperature, snow cover and sea level has been widely demonstrated (IPCC, 2007). However, the impact of climate change on natural risks is still not clear, and the degree of uncertainty is high. The main problem lays in the complexity of the factors involved in the production of natural disasters, mainly those related with the vulnerability (in the more holistic sense of the expression), that is continuously being modified. In terms of the impact of climate change on hazards, the analysis is still complicated, and this difficulty increases when meteorological hazards that combine meteorological factors with other ones (human and/or natural) are considered (i.e. floods, wet landslides, forest fires, etc.). The Advisory Council for the Sustainable Development of Catalonia (CADS) is an advisory body which gives strategic advice to the Catalan Government in the field of sustainable development. This contribution shows the main results of a recent report elaborated by the CADS that analyses the present and potential evolution of natural risks in Catalonia (NE of Iberian Peninsula) and the influence of climate change in it. The analysis is made from the point of view of sustainable development, having in mind the international approach (IPCC, 2007, 2011; UNISDR, 2009; Molin, 2009; Brauch, 2010) and with special incidence in potential problems related with security and civil protection. Conclusions identify as main problems those that will affect health (as a consequence of the increase of heat waves and temperature extremes) and water scarcity.

  16. Adapting Agricultural Water Use to Climate Change in a Post-Soviet Context: Challenges and Opportunities in Southeast Kazakhstan.

    2017-01-01

    The convergence of climate change and post-Soviet socio-economic and institutional transformations has been underexplored so far, as have the consequences of such convergence on crop agriculture in Central Asia. This paper provides a place-based analysis of constraints and opportunities for adaptation to climate change, with a specific focus on water use, in two districts in southeast Kazakhstan. Data were collected by 2 multi-stakeholder participatory workshops, 21 semi-structured in-depth interviews, and secondary statistical data. The present-day agricultural system is characterised by enduring Soviet-era management structures, but without state inputs that previously sustained agricultural productivity. Low margins of profitability on many privatised farms mean that attempts to implement integrated water management have produced water users associations unable to maintain and upgrade a deteriorating irrigation infrastructure. Although actors engage in tactical adaptation measures, necessary structural adaptation of the irrigation system remains difficult without significant public or private investments. Market-based water management models have been translated ambiguously to this region, which fails to encourage efficient water use and hinders adaptation to water stress. In addition, a mutual interdependence of informal networks and formal institutions characterises both state governance and everyday life in Kazakhstan. Such interdependence simultaneously facilitates operational and tactical adaptation, but hinders structural adaptation, as informal networks exist as a parallel system that achieves substantive outcomes while perpetuating the inertia and incapacity of the state bureaucracy. This article has relevance for critical understanding of integrated water management in practice and adaptation to climate change in post-Soviet institutional settings more broadly.

    Full Text Available Abstract Background Wood heating is recommended in several countries as a climate change (CC adaptation measure, mainly to increase the autonomy of households during power outages due to extreme climatic events. The aim of this study was to examine various perceptions and individual characteristics associated with wood heating through a survey about CC adaptations. Methods A telephone survey (n = 2,545 of adults living in the southern part of the province of Québec (Canada was conducted in the early fall season of 2005. The questionnaire used closed questions and measured the respondents' beliefs and current adaptations about CC. Calibration weighting was used to adjust the data analysis for the respondent's age and language under stratified sampling based on health regions. Results More than three out of four respondents had access to a single source of energy at home, which was mainly electricity; 22.2% combined two sources or more; 18.5% heated with wood occasionally or daily during the winter. The prevalence of wood heating was higher in the peripheral regions than in the more urban regions, where there was a higher proportion of respondents living in apartments. The prevalence was also higher with participants completely disagreeing (38.5% with the eventual prohibition of wood heating when there is smog in winter, compared to respondents somewhat disagreeing (24.2% or agreeing (somewhat: 17.5%; completely: 10.4% with the adoption of this strategy. It appears that the perception of living in a region susceptible to winter smog, smog warnings in the media, or the belief in the human contribution to CC, did not influence significantly wood heating practices. Conclusion Increased residential wood heating could very well become a maladaptation to climate change, given its known consequences on winter smog and respiratory health. It would thus be appropriate to implement a long-term national program on improved and controlled residential wood

  2. Breeding success of a marine central place forager in the context of climate change: A modeling approach.

    Directory of Open Access Journals (Sweden)

    Lauriane Massardier-Galatà

    Full Text Available In response to climate warming, a southward shift in productive frontal systems serving as the main foraging sites for many top predator species is likely to occur in Subantarctic areas. Central place foragers, such as seabirds and pinnipeds, are thus likely to cope with an increase in the distance between foraging locations and their land-based breeding colonies. Understanding how central place foragers should modify their foraging behavior in response to changes in prey accessibility appears crucial. A spatially explicit individual-based simulation model (Marine Central Place Forager Simulator (MarCPFS, including bio-energetic components, was built to evaluate effects of possible changes in prey resources accessibility on individual performances and breeding success. The study was calibrated on a particular example: the Antarctic fur seal (Arctocephalus gazella, which alternates between oceanic areas in which females feed and the land-based colony in which they suckle their young over a 120 days rearing period. Our model shows the importance of the distance covered to feed and prey aggregation which appeared to be key factors to which animals are highly sensitive. Memorization and learning abilities also appear to be essential breeding success traits. Females were found to be most successful for intermediate levels of prey aggregation and short distance to the resource, resulting in optimal female body length. Increased distance to resources due to climate warming should hinder pups' growth and survival while female body length should increase.

    Understanding observed patterns of connectivity requires an understanding of the evolutionary processes that determine genetic structure among populations, with the most common models being associated with isolation by distance, allopatry or vicariance. Pinnipeds are annual breeders with the capacity for extensive range overlap during seasonal migrations, establishing the potential for the evolution of isolation by distance. Here, we assess the pattern of differentiation among six breeding colonies of the southern elephant seal, Mirounga leonina, based on mtDNA and 15 neutral microsatellite DNA markers, and consider measures of their demography and connectivity. We show that all breeding colonies are genetically divergent and that connectivity in this highly mobile pinniped is not strongly associated with geographic distance, but more likely linked to Holocene climate change and demographic processes. Estimates of divergence times between populations were all after the last glacial maximum, and there was evidence for directional migration in a clockwise pattern (with the prevailing current) around the Antarctic. We discuss the mechanisms by which climate change may have contributed to the contemporary genetic structure of southern elephant seal populations and the broader implications. © 2016 European Society For Evolutionary Biology.

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. The examination of integration...

    Coastal communities worldwide rely on small-scale artisanal fisheries as a means of increasing food security and alleviating poverty. Even small-scale fishing activities, however, are prone to resource depletion and environmental degradation, which can erode livelihoods in the long run. Thus, there is a pressing need to identify viable and resilient artisanal fisheries, and generate knowledge to support management within the context of a rapidly changing climate. We examined the ecosystem-level consequences of an artisanal kelp fishery (Macrocystis pyrifera), finding small-scale harvest of this highly productive species poses minimal impacts on kelp recovery rates, survival, and biomass dynamics, and abundances of associated commercial and culturally important fish species. These results suggest that small-scale harvest poses minimal trade-offs for the other economic benefits provided by these ecosystems, and their inherent, spiritual, and cultural value to humans. However, we detected a negative impact of warmer seawater temperatures on kelp recovery rates following harvest, indicating that the viability of harvest, even at small scales, may be threatened by future increases in global ocean temperature. This suggests that negative impacts of artisanal fisheries may be more likely to arise in the context of a warming climate, further highlighting the widespread effects of global climate change on coastal fisheries and livelihoods. © 2016 by the Ecological Society of America.

    Full Text Available In the context of climate change in Romania, we proposed to study the improvement of the country's flora by introducing an ornamental and beneficial species of temperate climate. Studies undertaken in spring 2017 indicate that Asimina triloba (L. Dunal flowers under conditions in Romania similar to those in the area of origin. Thus, we found that the beginning of vegetation in flowering buds took place in the first tenth of April and continued in stages until the start of the third trimester of April, when the flowering bud dimensions were over 15 mm in diameter, while the entire period of flowing took place from 24.04-20.05. One influence on the start of vegetation in flowing buds was the average daytime temperature recorded in the planting zone of Asimina triloba (L.

    Full Text Available Heat waves are a public health concern in Australia and unprecedented heat waves have been recorded in Adelaide over recent years. The aim of this study was to examine the perception and attitudes towards heat waves in the context of climate change among a group of residents in Adelaide, an Australian city with a temperate climate. A cross-sectional study was conducted in the summer of 2012 among a sample of 267 residents. The results of the survey found that television (89.9%, radio (71.2%, newspapers (45.3% were the main sources from which respondents received information about heat waves. The majority of the respondents (73.0% followed news about heat waves very or somewhat closely. About 26.6% of the respondents were extremely or very concerned about the effects of heat waves on them personally. The main issues that were of personal concern for respondents during a heat wave were their personal comfort (60.7%, their garden (48.7%, and sleeping well (47.6%. Overall, respondents were more concerned about the impacts of heat waves to the society than on themselves. There was a significant association between gender (χ² = 21.2, df = 3, p = 0.000, gross annual household income (p = 0.03 and concern for the societal effects of heat waves. Less than half (43.2% of the respondents believed that heat waves will extremely or very likely increase in Adelaide according to climate projections. Nearly half (49.3% believed that the effects of heat waves were already being felt in Adelaide. These findings may inform the reframing and communication strategies for heat waves in Adelaide in the context of climate change.

    2017-07-01

    Full Text Available Groundwater in the Klela basin in Mali, a subbasin of the Bani basin (one of the main tributaries of the Niger River, is required for domestic use, irrigation and livestock. Furthermore, water supply of the city of Sikasso directly depends on the groundwater resources, which are under pressure caused by increased water demand as well as climate variability and climate change. As a consequence, freshwater availability is being threatened which can have a direct negative impact on irrigation agriculture. The aim of this study was to evaluate future behavior of groundwater resources in the context of climate change and population growth using socio-economic and population growth scenarios for water demand and the Representative Concentration Pathways scenarios (RCP4.5 and RCP8.5 data for calculating groundwater recharge using the Thornthwaite model. The WEAP (Water Evaluation and Planning system model was applied to balance water availability and demand and to compute changes in groundwater storage up to 2050. The overall results show that groundwater recharge as well as storage is decreasing over time, especially in the 2030s which can lead to severe agricultural droughts in this period. Recharge declined by approximatively 49% and stored groundwater by 24% over the study period.

    The integration of scientific knowledge about possible climate change impacts on water resources has a direct implication on the way water policies are being implemented and evolving. This is particularly true regarding various technical steps embedded into the EU Water Framework Directive river basin management planning, such as risk characterisation, monitoring, design and implementation of action programmes and evaluation of the "good status" objective achievements (in 2015). The need to incorporate climate change considerations into the implementation of EU water policy is currently discussed with a wide range of experts and stakeholders at EU level. Research trends are also on-going, striving to support policy developments and examining how scientific findings and recommendations could be best taken on board by policy-makers and water managers within the forthcoming years. This paper provides a snapshot of policy discussions about climate change in the context of the WFD river basin management planning and specific advancements of related EU-funded research projects. Perspectives for strengthening links among the scientific and policy-making communities in this area are also highlighted. Copyright © 2012 Elsevier B.V. All rights reserved.

  16. Global vs climate change

    International Nuclear Information System (INIS)

    Watson, H.L.; Bach, M.C.; Goklany, I.M.

    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

    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...

    Shakespear Mudombi

    2013-09-01

    Full Text Available The objective of the study was to assess perceptions of rural household heads with regard to various aspects of water access and climate change, and to evaluate whether there were significant differences in perceptions of respondents from female-headed and male-headed households. The study is based on a cross-sectional survey of 300 respondents conducted in the Seke and Murewa districts of Zimbabwe in 2011. The analysis included mainly descriptive statistics. The majority of both female-headed and male-headed households relied on rainfall for their crops, rivers were cited as the main water source for their livestock and protected wells supplied water for household use. Households experienced water shortages, which were attributed mainly to reduced rainfall. The general perception was that there would be less water available in future, with a greater proportion of female-headed than male-headed households perceiving such difficulties. However, very few respondents indicated that they would consider emigrating, although female-headed households were more likely to consider emigrating than male-headed households. A considerable number of respondents indicated that they did not have any means to overcome the water shortages. This highlights the need for interventions such as training and empowerment of individuals with regard to sustainable water use and management.

  2. Microbial Contamination Detection in Water Resources: Interest of Current Optical Methods, Trends and Needs in the Context of Climate Change

    Directory of Open Access Journals (Sweden)

    Aude-Valérie Jung

    2014-04-01

    Full Text Available Microbial pollution in aquatic environments is one of the crucial issues with regard to the sanitary state of water bodies used for drinking water supply, recreational activities and harvesting seafood due to a potential contamination by pathogenic bacteria, protozoa or viruses. To address this risk, microbial contamination monitoring is usually assessed by turbidity measurements performed at drinking water plants. Some recent studies have shown significant correlations of microbial contamination with the risk of endemic gastroenteresis. However the relevance of turbidimetry may be limited since the presence of colloids in water creates interferences with the nephelometric response. Thus there is a need for a more relevant, simple and fast indicator for microbial contamination detection in water, especially in the perspective of climate change with the increase of heavy rainfall events. This review focuses on the one hand on sources, fate and behavior of microorganisms in water and factors influencing pathogens’ presence, transportation and mobilization, and on the second hand, on the existing optical methods used for monitoring microbiological risks. Finally, this paper proposes new ways of research.

    Interdisciplinarity has become synonymous with all things progressive about research and education. This is so not simply because of a philosophical belief in the heterogeneity of knowledge but because of the scientific and social complexities of problems of major concern. The increased demand for improved climate knowledge and information has increased pressure to support planning under changing rates of extremes event occurrence, is well-documented. The application of useful climate data, information and knowledge requires multiple networks and information services infrastructure that support planning and implementation. As widely quoted, Pasteur's quadrant is a label given to a class of scientific research methodologies that seeks fundamental understanding of scientific problems and, simultaneously, to benefit society-what Stokes called "use-inspired research". Innovation, in this context, has been defined as "the process by which individuals and organizations generate new ideas and put them into practice". A growing number of research institutes and programs have begun developing a cadre of professionals focused on integrating basic and applied research in areas such as climate risk assessment and adaptation. There are now several examples of where researchers and teams have crafted examples that include affected communities. In this presentation we will outline the lessons from several efforts including the PACE program, the RISAs, NIDIS, the Climate Services Information System and other interdisciplinary service-oriented efforts in which the author has been involved. Some early lessons include the need to: Recognize that key concerns of social innovation go beyond the projections of climate and other global changes to embrace multiple methods Continue to train scientists of all stripes of disciplinary norms, but higher education should also prepare students who plan to seek careers outside of academia by increasing flexibility in graduate training programs

    Full Text Available The challenges of sustainable development and climate change open up the new possibilities in understanding the importance, principles and methodologies of urban renewal. The paper discusses the problem of abandoned buildings and complexes and their possible reuse in the context of climate change and sustainability at an example of the study of repurposing the military barracks complex in Bela Crkva conducted in the Institute of Architecture and Urban & Spatial Planning of Serbia in 2012. The conceptual solution of the variant 2, based on the idea of climate-aware and socially responsible design, has been embedded into the basic program scheme of the new complex, which includes the establishment of a university campus, construction of experimental social housing, cultural and artistic facilities, as well as urban agriculture, including the use of alternative energy sources and respecting the principles of energy efficiency. The problems of the abandonment of military buildings and complexes, as well as the recommendations for their adaptation, taking into account the past experience and the current environmental problems, are pointed out in the concluding remarks.

    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.

    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)

    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 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.

    In its first part, this collective publication addresses the decennial and centuries-old variations of climate: perspectives and implications of climate change for the 21. century, questions remaining about the understanding of climate change from its sources to its modelling, extreme climate variations and societies during the last millennium. The contributions of the second part outline how chemistry is a tool to study climate change: ice chemistry as an archive of our past environment, observations and predictions on sea level rise, relationship between atmosphere chemistry and climate. The third set of contributions discusses the transformation of the energy system for a cleaner atmosphere and the management of the climate risk: the chemical processing of CO_2, actions of chemical companies to support the struggle against climate change, relationship between barrel price and renewable energies, relationship between grid complexity and green energy. The last part outlines the role chemistry can have to be able to do without fossil fuels: chemistry in front of challenges of transformation of the energy system, the use of micro-algae, the use of hydrogen as a vector of energy transition

    Sustainability education is an approach to learning that builds knowledge, skills, and values needed to create lasting economic prosperity, environmental health, and social justice. In collaboration with Creative Change Educational Solutions (http://www.creativechange.net/) and with funding from the Clarence E. Heller Charitable Foundation and NASA, scientists and science educators at San José State University (SJSU) are developing an online 'Introduction for Sustainability' course for middle and high school educators. The module will introduce sustainability as a context for learning, highlight connections to climate change science and solutions, and provide strategies for linking the environmental, economic and social dimensions of climate destabilization to fundamental sustainability concepts. This self-paced course will be piloted during the 2013-2014 academic year. Upon completion, participants will receive inexpensive university credit ( $50/unit) from SJSU. Course goals are to demonstrate the applicability of sustainability themes across disciplines; increase learners' knowledge about the causes and impacts of climate change and related sustainability challenges; and support learners in integrating course content and methods into their classroom teaching. Course activities combine: 1) reading selections and questions; 2) online discussion; 3) digital media (short videos and tutorials); and 4) journal entries and other written assignments, including consideration of how course content aligns with the Common Core and Next Generation Science Standards. The module is divided into five sections: 1) Defining What Matters - What Do We All Need for a Fulfilling Life?; 2) The Commons and Ecosystem Services; 3) Causes and Impacts of Climate Change; 4) Individual and Collective Actions to Mitigate Its Effects; and 5) Integrating Sustainability into the Curriculum. Initial recruitment for the course will take place among participants in workshops offered by the Bay

    Ecosystem services are a relatively new concept in forestry. While the current forestry practice still describes non-timber forest products as secondary, the concept of ecosystem services originating from FAO and researchers of ecosystem services equally emphasises the economic significance of non-timber products and services forest ecosystems provide as of those primary products - timber biomass. Forest ecosystem services are only a segment of the overall context of ecosystem services in whi...

    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.

    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...

    Hesselmans, G.H.F.M.

    1993-08-01

    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

    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

    2012-01-01

    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...

    Since 2005, the Gulf of Maine Research Institute has brought 70% of Maine's 5th/6th grade cohort annually to our marine research lab for a 2.5-hour exploration of ecosystem complexity. Using a digital platform, tools of science, and live marine species, students consider the interconnections among key Gulf of Maine species while experiencing the process of authentic marine research. With funding from NASA, we are renovating the program's learning content, underlying technology, and physical interfaces to leverage NASA data sets. The new experience will emphasize development of students' data skills as they investigate the impacts of climate change in the Gulf of Maine. To do this, students will explore representations of rising ocean temperatures and connect that to representations of changes in the populations of key species like lobster and black sea bass. Past experience suggests the abstraction and synthesis required to make meaning from data visualizations is extremely challenging for this age student. We will report on an early round of informal testing with 250+ students to understand their ability to extract meaning from geospatial and graphical representations of change over time. We will also report on experiments that will be conducted in Fall 2017 to understand the kinds of informal learning experiences, and the sequences of data representations, that best support growth in students' ability to interpret a range of representations. Finally, we will discuss the project's work to extend the learning experiences 1) back into the classroom, including through citizen science; and 2) out to regional science centers for adaptation to investigations of local climate impacts.

    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.

    1991-01-01

    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

    2005-01-01

    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)

    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.

    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.

    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

    Full Text Available 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

    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.

    Floods are one of the most costly hazards and frequency analysis of river discharges is an important part of the tools at our disposal to evaluate their inherent risks and to provide an adequate response. In comparison to the common examination of annual streamflow maximums, peaks over threshold (POT) is an interesting alternative that makes better use of the available information by including more than one flood event per year (on average). However, a major challenge is the selection of a satisfactory threshold above which peaks are assumed to respect certain conditions necessary for an adequate estimation of the risk. Additionally, studies have shown that POT is also a valuable approach to investigate the evolution of flood regimes in the context of climate change. Recently, automatic procedures for the selection of the threshold were suggested to guide that important choice, which otherwise rely on graphical tools and expert judgment. Furthermore, having an automatic procedure that is objective allows for quickly repeating the analysis on a large number of samples, which is useful in the context of large databases or for uncertainty analysis based on a resampling approach. This study investigates the impact of considering such procedures in a case study including many sites across Canada. A simulation study is conducted to evaluate the bias and predictive power of the automatic procedures in similar conditions as well as investigating the power of derived nonstationarity tests. The results obtained are also evaluated in the light of expert judgments established in a previous study. Ultimately, this study provides a thorough examination of the considerations that need to be addressed when conducting POT analysis using automatic threshold selection.

    This book is together a contemporary history book and a global dossier about a topic of prime importance in our civilization. It treats of the history of science, of ideas and events put in the modern civilization context, of science situation and scientific controversies, of the media aspects, of carbon economy and its related business, of Al Gore's and Maurice Strong's biographies, and finally, it makes a critical geopolitical analysis and makes proposals for a renovated ecology. In the conclusion, the author shows how climate change has become the hobbyhorse of a new thinking trend, namely the New World Order, aiming at conducting people to the acceptance of constraining policies encompassing the energy security of nations, new taxes, a worldwide economic disruption, the limitation of the World's population, and a World governance supported by the United Nations and not constrained by classical democratic rules.

    Climate change is a true reality as long as we understand the crisis that is happening on our planets climate, particularly marked from the middle of last century. Natural fluctuations in carbon dioxide concentration and the oscillations of the orbital planets parameters have been amplified by the system of ocean currents and the sequence of freezing and thawing areas in the circumpolar Arctic. Thus, it is considered that carbon sinks are a solution to mitigate the effects of climate change. The pressures that climate change can result in ecosystems (land, water,...), is a significant additional pressure on terrestrial ecosystems, already seriously affected today by pollution, over exploitation and land fragmentation. Finally, we stop at the analysis of the Spanish reality. (Author)

    Remember the scenes from New Orleans of flooded streets and scavenging people? One year on and little progress is evident in achieving the step-change needed in controlling greenhouse gases. Hurricane Katrina showed only too vividly the massive power of natural forces combined with inadequate preparation. The flood waters washed away and exposed fully the lack of planning and low priority given to securing life and livelihoods, especially of the more vulnerable groups in the community. If this is what a whirlwind can bring in the southern USA, what might we reap in further storms and droughts tomorrow in poorer parts of the world? New research findings point to the likelihood of larger, faster and more substantial changes to our climate system. The African continent is particularly vulnerable to adverse changes in climate, the evidence for which is becoming more and more stark.

    The investigation of climatic processes and behaviour examines the effects of climatic changes on human beings and the surrounding environment. The authors discuss, in a wide-subject perspective, the regional impacts of the greenhouse effect, increase of the sea level, and changed conditions of both precipitation and wind using the North and Baltic Sea as examples. In this effort, questions dealing with changes of water level, motion and (disturbance) of the sea and morphodynamic in the coastal apron, in reference to requirements on a future protection of the shore, are handled. In addition, not only the aspects of ecosystem-orientated adaption in the strip of land between the continent northern islands 'Wattenmeer' and ground landscape (Bodenlandschaft) are taken into consideration, but also the impact of these on human beings and their interest to use the coastal regions.

    Climate change communication is complicated by complexity of the scientific problem, multiple perspectives on the magnitude of the risk from climate change, often acrimonious disputes between scientists, high stakes policy options, and overall politicization of the issue. Efforts to increase science literacy as a route towards persuasion around the need for a policy like cap and trade have failed, because the difficulty that a scientist has in attempting to make sense of the social and political complexity is very similar to the complexity facing the general public as they try to make sense of climate science itself. In this talk I argue for a shift from scientists and their institutions as information disseminators to that of public engagement and enablers of public participation. The goal of engagement is not just to inform, but to enable, motivate and educate the public regarding the technical, political, and social dimensions of climate change. Engagement is a two-way process where experts and decision-makers seek input and learn from the public about preferences, needs, insights, and ideas relative to climate change impacts, vulnerabilities, solutions and policy options. Effective public engagement requires that scientists detach themselves from trying to control what the public does with the acquired knowledge and motivation. The goal should not be to "sell" the public on particular climate change solutions, since such advocacy threatens public trust in scientists and their institutions. Conduits for public engagement include the civic engagement approach in the context of community meetings, and perhaps more significantly, the blogosphere. Since 2006, I have been an active participant in the climate blogosphere, focused on engaging with people that are skeptical of AGW. A year ago, I started my own blog Climate Etc. at judithcurry.com. The demographic that I have focused my communication/engagement activities are the technically educated and scientifically

    In the last decade marked changes of climatic factors have been observed, such as increases in average global earth temperatures, the amount of precipitation and the number of extreme weather events. Green house gases influence the energy flow in the atmosphere by absorbing infra-red radiation. An overview of the Austrian greenhouse gas emissions is given, including statistical data and their major sources. In 1999 the emissions of all six Kyoto greenhouse gases ( CO 2 , CH 4 , N 2 O, HFC s , PFC s and SF 6 ) amounted to 79.2 million tonnes of CO 2 equivalents . A comparison between the EC Members states is also presented. Finally the climate change strategy prepared by the Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management together with other ministries and the federal provinces is discussed, which main aim is to lead to an annual emission reduction of 16 million tonnes of CO 2 .

  17. Managing Climate Change Risks

    2003-07-01

    Issues of uncertainty, scale and delay between action and response mean that 'dangerous' climate change is best managed within a risk assessment framework that evolves as new information is gathered. Risk can be broadly defined as the combination of likelihood and consequence; the latter measured as vulnerability to greenhouse-induced climate change. The most robust way to assess climate change damages in a probabilistic framework is as the likelihood of critical threshold exceedance. Because vulnerability is dominated by local factors, global vulnerability is the aggregation of many local impacts being forced beyond their coping ranges. Several case studies, generic sea level rise and temperature, coral bleaching on the Great Barrier Reef and water supply in an Australian catchment, are used to show how local risk assessments can be assessed then expressed as a function of global warming. Impacts treated thus can be aggregated to assess global risks consistent with Article 2 of the UNFCCC. A 'proof of concept' example is then used to show how the stabilisation of greenhouse gases can constrain the likelihood of exceeding critical thresholds at both the both local and global scale. This analysis suggests that even if the costs of reducing greenhouse gas emissions and the benefits of avoiding climate damages can be estimated, the likelihood of being able to meet a cost-benefit target is limited by both physical and socio-economic uncertainties. In terms of managing climate change risks, adaptation will be most effective at reducing vulnerability likely to occur at low levels of warming. Successive efforts to mitigate greenhouse gases will reduce the likelihood of reaching levels of global warming from the top down, with the highest potential temperatures being avoided first, irrespective of contributing scientific uncertainties. This implies that the first cuts in emissions will always produce the largest economic benefits in terms of avoided

  18. On climate change and economic growth

    Fankhauser, Samuel; Tol, Richard S.J.

    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

    This book tries to answer today's main environmental questions relative to the climatic change: how our massive petroleum and coal consumption has led to a greenhouse effect? What will happen tomorrow when Chinese and Indian people will reach the same energy consumption levels as people of western countries? Is it too late to reverse the trend? If solar energy is the long-term solution, what can we do in the meantime? The author presents the conditions we must fulfill to keep the Earth in a good environmental condition: 1 - a brief story of energy; 2 - the climatic changes and their secrets; 3 - the greenhouse effect: necessary for life but worrying for the future; 4 - the energy demand and the stakes; 2 - fossil fuels: abundance or shortage? 6 - can we fight against greenhouse gases? 7 - the nuclear energy (reactors and wastes management); 8 - the renewable energies: a necessary contribution at the century scale and the unique answer at the millennium scale; 9 - the time of main choices is not so far; 10 - two questions (energy demand and climatic change) and a unique answer (sustainable development).

    Full Text Available Recently, considerable focus, e.g., in the fifth IPCC (Intergovernmental Panel on Climate Change Assessment Report (2014 has been trained on why adaptation and mitigation have not been developed more than at present, with relatively few local government actions taken compared with, for example, more discursive policy agreement on the importance of the issue of climate change. Going beyond a focus on general limits and barriers, this comment suggests that one important issue is that climate change has not yet been sufficiently integrated into the state regulative structure of legislation and policy-making. A comparison between three cases suggests that local developments that are not supported in particular by binding regulation are unlikely to achieve the same general level of implementation as issues for which such regulative demands (and thereby also requirements for prioritization exist. This constitutes an important consideration for the development of adaptation and mitigation as policy areas, including on the local level.

    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.

    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.

    The causes for climatic change in the period between 3000 and 1250 BC was different from what present scenario portends. After industrialization, temperatures has arisen by 0.5 degrees centigrade every 100 years since factories started to spew out smoke. Over the last two centuries, the concentration of Carbon Dioxide in the atmosphere has increased by more than 25% from about 275ppm in the 18th Century to more than 350ppm at the present time while the current level is expected to double by the year 2050. The increase in Carbon Dioxide and together with other greenhouse gases in the atmosphere will trap the sun's radiation causing the mean global temperatures to rise by between 1 degree and 5 degrees centigrade by 2050. The climatic change affects forestry in many ways for instance, temperatures determines the rate at which enzymes catalyze biochemical reactions while solar radiation provide the energy which drive light reactions in photosynthesis. On the other hand, water which is a component of climate is a universal solvent which enables plants to transport nutrients through the transpirational stream, and similarly transport photosynthates from the leave to all parts of the plants. It is a raw material for photosynthesis and important for maintaining turgidity, which is important for growth

    How will increases in levels of CO 2 and changes in temperature affect food production? A recently issued report analyzes prospects for US agriculture 1990 to 2030. The report, prepared by a distinguished Task Force, first projects the evolution of agriculture assuming increased levels of CO 2 but no climate change. Then it deals with effects of climate change, followed by a discussion of how greenhouse emissions might be diminished by agriculture. Economic and policy matters are also covered. How the climate would respond to more greenhouse gases is uncertain. If temperatures were higher, there would be more evaporation and more precipitation. Where would the rain fall? That is a good question. Weather in a particular locality is not determined by global averages. The Dust Bowl of the 1930s could be repeated at its former site or located in another region such as the present Corn Belt. But depending on the realities at a given place, farmers have demonstrated great flexibility in choosing what they may grow. Their flexibility has been increased by the numerous varieties of seeds of major crops that are now available, each having different characteristics such as drought resistance and temperature tolerance. In past, agriculture has contributed about 5% of US greenhouse gases. Two large components have involved emissions of CO 2 from farm machinery and from oxidation of organic matter in soil due to tillage. Use of diesel fuel and more efficient machinery has reduced emissions from that source by 40%. In some areas changed tillage practices are now responsible for returning carbon to the soil. The report identifies an important potential for diminishing net US emissions of CO 2 by growth and utilization of biomass. Large areas are already available that could be devoted to energy crops

CO 2 is the most important GHG its contribution to the radioactive forcing of climate is estimated in about 70%. Changes in the global concentration of these gases depend on the level of emissions as a by-product of economic activities, the natural assimilative capacity of the global ecosystem, and the abatement activities.

    1991-01-01

    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

    1976-03-01

    The effects of global warming on economies and societies are discussed. The history of past climate changes in North America is summarized, ranging from short period variations to changes over centuries and millenia. To aid in forecasting the effects of future climatic variation, historical episodes that have had well documented socio-economic effects are examined. These episodes include: the variability period of 1895-1905 characterized by cool climate, wet periods in the northwestern great plains, sustained drought in the Pacific northwest, extreme cold in the gulf states, and the Galveston flood; the midwestern drought of 1933-1937, characterized by drought on the great plains, very cold snowy winters, hot summers, and massive soil erosion; 1935-36, characterized by a very cold winter and a very hot summer; the Mexican drought of 1937-45, characterized by recurrent drought in Mexico; the variable period of 1950-1958, characterized by Pacific coast drought, drought and flood on the great plains, cold and warm winters and summers, wheat rust, coastal storms and forest fires; the Eastern urban drought of 1961-66 characterized by sustained cold drought in eastern North America; the sea ice period of 1964-65 and 1971-72, characterized by heavy sea ice; snowfall period of 1970-74 characterized by heavy winter snowfalls and a late, wet spring; and the global interdependence period of 1972 characterized by cold winters in Canada and USSR, drought in Asia, the Sahel, Australia, central America, floods in North Africa, high ocean surface temperatures off Peru, and unusually cold weather in the corn belt. 33 refs., 15 figs., 7 tabs.

    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

    Cooper, Richard N.

    2012-01-01

    This paper argues that the 2009 pledge of $100 billion in 2020 by rich countries for mitigation and adaptation should not be used for mitigation by commercial firms in developing countries, since that would artificially create competitive advantage for such firms and provoke protectionist reactions in the rich countries where firms must bear the costs of mitigation, thereby undermining the world trading system. The costs of heating the earth's surface should be borne by all emitters, just as the price of copper and other scarce resources is paid by all users, rich or poor. That will still leave scope for rich country help in adaptation to climate change and in bringing to fruition new technologies to reduce emissions. - Highlights: ► Slowing climate change significantly cannot occur without the participation of the largest emitters among developing countries. ► The cost of GHG mitigation must be the same for all competing firms, wherever they are located. ► The world trading system is seriously at risk in the face of a poorly designed system for global mitigation of greenhouse gases. ► No significantly emitting firm, anywhere, public or private, should be protected from the incentive to reduce its emissions. ► Higher prices for fossil fuels need not reduce national growth rates in consuming countries.

    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.

    2018-03-01

    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.

  14. Climate changes and biodiversity

    International Nuclear Information System (INIS)

    Bertelsmeier, C.

    2011-01-01

    As some people forecast an average temperature increase between 1 and 3.5 degrees by the end of the century, with higher increases under high latitudes (it could reach 8 degrees in some regions of Canada), other changes will occur: precipitations, sea level rise, reductions in polar ice, extreme climatic events, glacier melting, and so on. The author discusses how these changes will impact biodiversity as they will threat habitat and living conditions of many species. Some studies assess a loss of 15 to 37 per cent of biodiversity by 2050. Moreover, physiology is influenced by temperature: for some species, higher temperatures favour the development of female embryos, or the increase of their population, or may result in an evolution of their reproduction strategy. Life rhythm will also change, for plants as well as for animals. Species will keep on changing their distribution area, but some others will not be able to and are therefore threatened. Finally, as the evolutions concern their vectors, some diseases will spread in new regions

    1992-01-01

    Principles that guide Canada's Green Plan with respect to global warming are outlined. These include respect for nature, meeting environmental goals in an economically beneficial manner, efficient use of resources, shared responsibilities, federal leadership, and informed decision making. The policy side of the international Framework Convention on Climate Change is then discussed and related to the Green Plan. The Convention has been signed by 154 nations and has the long-term objective of stabilizing anthropogenic greenhouse gas concentrations in the atmosphere at levels that prevent dangerous interference with the climate system. Some of the Convention's commitments toward achieving that objective are only applicable to the developed countries. Five general areas of commitment are emissions reductions, assistance to developing countries, reporting requirements, scientific and socioeconomic research, and education. The most controversial area is that of limiting emissions. The Convention has strong measures for public accountability and is open to future revisions. Canada's Green Plan represents one country's response to the Convention commitments, including a national goal to stabilize greenhouse gas emissions at the 1990 level by the year 2000

  18. Indications of climatic change

    International Nuclear Information System (INIS)

    2005-04-01

    The earth's annual mean global temperature increased by around 0,6 C during the 20 century, with wide regional differences. Even if solar activity has played some part in the mean temperature rise and some greenhouse gases are present naturally in the atmosphere, enhancing of the greenhouse effect due to the human activities is responsible for a large and increasing part of the observed warming. The work of the Intergovernmental Panel on Climate Change confirms the future increase under all scenarios. Depending on the efforts made by mankind to limit greenhouse gases emissions, the global mean temperature in 2100 could be between 1,4 and 5,8 C higher than in 2000. (A.L.B.)

    Global climate change has ceased to be strictly an environmental threat, lurking in the future. Its potential impacts could well make it the greatest social and economic challenge that humanity will have to face in the coming century. The first is competition. An energy revolution is now in the making, with advanced new technologies such as fuel cells, photovoltaics, wind turbines and flywheels entering the market. The reason why we moved beyond the horse and buggy a hundred years ago was not because we ran out of hay. Similarly, there is no doubt that the planet still has impressive oil reserves. However, as was the case when the oil era first emerged, those industries that successfully incorporate the new technologies will be well positioned to succeed economically in the 21 st century

    Global economic integration and growth contribute much to the construction of energy plants, vehicles and other industrial products that produces carbon emission and in effect cause the destruction of the environment. A coordinated policy and response worldwide to curb emissions and to effect global climate change must be introduced. Improvement in scientific understanding is required to monitor how much emission reduction is necessary. In the near term, especially in the next seven years, sustained research and development for low carbon or carbon-free energy is necessary. Other measures must also be introduced, such as limiting the use of vehicles, closing down inefficient power plants, etc. In the long term, the use of the electric car, use solar energy, etc. is required. Reforestation must also be considered to absorb large amounts of carbon in the atmosphere

    Faced with climate change what is the position of scientists, of economists and of political decision makers? And the one of philosophers, of moralists, and of theologians? Finally, what is the position of anyone of us? This question of ethical aspect has been rarely tackled in France so far. Prepared after a colloquium held in Paris in 2009, this book combines scientifical, philosophical, moral and theological perspectives accessible to anyone. It stresses on the novelty and urgency of the ethical thought concerning a question having a strong impact of the humanity future, and more particularly on the future of the most vulnerable of us. If the human being is capable to mobilize himself collectively for a universal cause, he can stay on individualistic positions as well, in particular when he has to care of the fate of the generations to come. This book is a philosophical-scientifical thought which aims at bringing together four main views on this issue. (J.S.)

    2009-01-01

    After having recalled the challenges the French forest has to face, and a brief overview of the status of forests in the world, this report proposes an overview of actions which are implemented to strengthen the carbon sequestration role of forests, at the international level and in France. It discusses the distribution of carbon, the forest carbon stocks (in the world, Europe and France), the actions against climate change, the costs and financing of the reduction of greenhouse gas emissions in the forest sector. It comments the status of international negotiations and how forests are taken into account. It presents the French forest and wood sector (characteristics of the forest in metropolitan France and overseas, wood as material and as energy). It recalls the commitment of the Grenelle de l'Environnement, and indicates the current forest studies

  3. Competitiveness and climate change

    International Nuclear Information System (INIS)

    Baron, R.

    2006-01-01

    The author addresses the relationship between competitiveness and climate policy beyond the issue of emission quota trading, and with taking into account links between different activities. For some sectors, demand may depend on measures undertaken to reduce emissions in the transport and building sectors. According to the author, these interactions could transform the industry on a middle term, more than the required technical changes aimed at the reduction of emissions. After a detailed analysis on these issues, this paper discusses the results of several studies dealing with the relationship between environmental regulation and competitiveness, and with global assessments of carbon leakages. Then, the author discusses the European directive which introduces the Emission Trading Scheme (ETS)

  4. Climate change policy position

    International Nuclear Information System (INIS)

    2002-11-01

    The Canadian Association of Petroleum Producers (CAPP) is a firm believer in the need to take action to mitigate the risks associated with climate change, and that clear government policy is called for. The principles of sustainable development must guide this policy development effort. The initiatives required to address greenhouse gas emissions over both the short and long term must be carefully considered, and it is up to industries to ensure their production efficiency and emission intensity. Promoting improved performance of industries in Canada and developing technology that can be deployed internationally for larger global effects represents Canada's best contribution to progress on greenhouse gas emissions. The increase in energy demand along with increases in population and economic growth have contributed to an increase in greenhouse gas emissions despite improved energy efficiency in industry. Significant damage to the economy will result if Canada is to meet its commitment under the Kyoto Protocol, forcing the country to buy large quantities of foreign credits instead of using those funds for increased research and development. CAPP indicated that an effective plan must be: balanced, equitable, responsible, competitive, focused on technology and innovation, and based on agreements on sectoral plans. Each of these principles were discussed, followed by the fundamentals of approach for upstream oil and gas. The framework for climate change policy was described as well as the elements of a sector plan. CAPP wants to work with all levels of government on an appropriate plan for Canada, that considers our unique circumstances. Canada can play a significant role on the international stage by properly implementing the policy position proposed by the CAPP without unnecessary risks to the economy. refs

  5. Our climate change actions

    International Nuclear Information System (INIS)

    2002-05-01

    One of the main tools utilized by the Canadian government to encourage the private sector and other organizations to monitor, report and implement measures for the reduction of greenhouse gas emissions is the Climate Change Voluntary Challenge and Registry (VCR), a program supported by several industry leaders in the oil and gas sector, such as the Canadian Energy Pipeline Association (CEPA). Financial resources and human efforts have expanded for the past seven years (since 1995) by the transmission pipeline companies with the aim of continuously reducing the emissions of greenhouse gas which have an impact on climate change. The successes achieved by member companies of CEPA are described in this document, resulting in limitations to the growth of greenhouse gas emissions by players in the sector. The three types of greenhouse gas emissions produced by transmission pipelines, carbon dioxide, methane, and nitrous oxide, and the process by which they are produced, are explained. The high growth in emissions by transmission pipelines is due to the higher amounts of energy required to move increasing volumes of natural gas. Some of the successes achieved by companies in direct emissions in the sector are: advances in inventory accuracy, greenhouse gas audits, measuring fugitive emissions, reducing emissions from fossil fuel combustion, state-of-the-art technology, energy efficiency, computer modelling, improving operational efficiency and replacing equipment. In indirect emissions, the measures implemented include efficiency of electricity use and helping consumers save. Using waste heat to create electricity, and offsets through cogeneration are measures that contribute to the successes in innovation

  6. Climate Change Mitigation A Balanced Approach to Climate Change

    CERN Document Server

    2012-01-01

    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�...

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

    International Nuclear Information System (INIS)

    Okoth-Ogendo, H.W.O.; Ojwang, J.B.

    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

  8. Preparing for climate change.

    Holdgate, M

    1989-01-01

    There is a distinct probability that humankind is changing the climate and at the same time raising the sea level of the world. The most plausible projections we have now suggest a rise in mean world temperature of between 1 degree Celsius and 2 degrees Celsius by 2030--just 40 years hence. This is a bigger change in a smaller period than we know of in the experience of the earth's ecosystems and human societies. It implies that by 2030 the earth will be warmer than at any time in the past 120,000 years. In the same period, we are likely to see a rise of 15-30 centimeters in sea level, partly due to the melting of mountain glaciers and partly to the expansion of the warmer seas. This may not seem much--but it comes on top of the 12-centimeter rise in the past century and we should recall that over 1/2 the world's population lives in zones on or near coasts. A quarter meter rise in sea level could have drastic consequences for countries like the Maldives or the Netherlands, where much of the land lies below the 2-meter contour. The cause of climate change is known as the 'greenhouse effect'. Greenhouse glass has the property that it is transparent to radiation coming in from the sun, but holds back radiation to space from the warmed surfaces inside the greenhouse. Certain gases affect the atmosphere in the same way. There are 5 'greenhouse gases' and we have been roofing ourselves with them all: carbon dioxide concentrations in the atmosphere have increased 25% above preindustrial levels and are likely to double within a century, due to tropical forest clearance and especially to the burning of increasing quantities of coal and other fossil fuels; methane concentrations are now twice their preindustrial levels as a result of releases from agriculture; nitrous oxide has increased due to land clearance for agriculture, use of fertilizers, and fossil fuel combustion; ozone levels near the earth's surface have increased due mainly to pollution from motor vehicles; and

    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.

    Addressing the question what the probability is of an anthropogenically induced change in the climate, leads to a number of other, underlying questions. These questions, which deal with the characteristics of climate, of climatic change, and of probabilistic statements on climatic change, should be addressed first. The long-term objective of the underlying study, i.e. a quantitative assessment of the risks and opportunities of the predicted climatic change, sets the context against which of those questions should be answered. In addition, this context induces extra questions, i.e. about the characteristics of risk

    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.

    Previous research findings display that after having seen popular climate change films, people became more concerned, more motivated and more aware of climate change, but changes in behaviors were short-term. 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.

    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.

    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

    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

  11. Scaling Climate Change Communication for Behavior Change

    Rodriguez, V. C.; Lappé, M.; Flora, J. A.; Ardoin, N. M.; Robinson, T. N.

    2014-12-01

    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.

    2004-01-01

    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.

  13. Migration and adaptation to climate change

    2007-11-15

    Climate change is having an undeniable impact on many human systems and behaviours, including population mobility. This is hardly surprising: migration is an adaptive response to changes in people's circumstances. Yet environmental factors are not the whole story. Socio-economic, political and cultural factors are also closely linked to population movement, and heavily influence vulnerability to both direct and indirect impacts of climate change. Shifts in migration patterns are a strategy of adaptation to complex transformations, and recognising and accommodating this is key in policies for sustainable development and poverty reduction in the context of growing environmental stress.

    2015-10-01

    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.

    1998-01-01

    Global climate change has emerged as one of today's most challenging and controversial policy issues. In this significant new contribution, a roster of premier scholars examines economic and social aspects of that far-reaching phenomenon. Although the 1997 summit in Kyoto focused world attention on climate, it was just one step in an ongoing process. Research by the U.N.'s Intergovernmental Panel on Climate Change (IPCC) has been ongoing since 1988. An extensive IPCC Working Group report published in 1995 examined the economic and social aspects of climate change. In this new volume, eminent economists assess that IPCC report and address the questions that emerge. William Nordhaus's introduction establishes the context for this book. It provides basic scientific background, reviews the IPCC's activities, and explains the genesis of the project

    This paper explored climate change challenges facing British Columbia in the context of 9 topical issues, notably biodiversity, extreme events, energy, water supply, crop adaptation, health risks, sea level rise, population dynamics and new technologies. Each issue was summarized in terms of threats, current responses in British Columbia and precedents being set in Canada. The key principles of adaptation to climate change were also reviewed. In addition, the paper explored ways to adopt smart adaptation strategies-policy responses to climate change that cut across all major government functions, such as infrastructure, energy, water, economic development, resource management and agriculture. The paper emphasized that strategies that respond to the climate challenge should acknowledge the links between adaptation and mitigation, or emissions reduction. Both concepts need major investment in research, education and infrastructure to support comprehensive, effective responses. refs., tabs., figs

    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.

    Peatlands harbour more than one-third of terrestrial carbon leading to the argument that the bryophytes, as major components of peatland ecosystems, store more organic carbon in soils than any other collective plant taxa. Plants of the genus Sphagnum are important components of peatland ecosystems and are potentially vulnerable to changing climatic conditions. However, the response of Sphagnum to rising temperatures, elevated CO2 and shifts in local hydrology have yet to be fully characterized. In this review, we examine Sphagnum biology and ecology and explore the role of this group of keystone species and its associated microbiome in carbon and nitrogen cycling using literature review and model simulations. Several issues are highlighted including the consequences of a variable environment on plant-microbiome interactions, uncertainty associated with CO2 diffusion resistances and the relationship between fixed N and that partitioned to the photosynthetic apparatus. We note that the Sphagnum fallax genome is currently being sequenced and outline potential applications of population-level genomics and corresponding plant photosynthesis and microbial metabolic modelling techniques. We highlight Sphagnum as a model organism to explore ecosystem response to a changing climate and to define the role that Sphagnum can play at the intersection of physiology, genetics and functional genomics. © 2014 The Authors.

    Full Text Available Global warming will affect all climatic variables and particularly rainfall patterns. The purpose of present investigation was to predict climatic parameters of Iran under future climate change and to compare them with the present conditions. For this reason, UKMO General Circulation Model was used for the year 2025 and 2050. By running the model, minimum and maximum monthly temperature and also maximum monthly rainfall for the representative climate stations were calculated and finally the effects of climate change on these variables based on pre-determined scenarios was evaluated. The results showed that averaged over all stations, mean temperature increase for spring in the year 2025 and 2050 will be 3.1 and 3.9, for summer 3.8 and 4.7, for autumn 2.3 and 3 and for winter 2.0 and 2.4 ºC, respectively. This increase will be more pronounced from North to the South and from East to the West parts of the country. Mean decrease in autumn rainfall for the target years of 2025 and 2050 will be 8 and 11 percent, respectively. This decrease is negligible for summer months. Length of dry season for the years 2025 and 2050 will be increased, respectively up to 214 and 223 days due to combined effects of increased temperature and decreased rainfall.

    The North Slope of Alaska is experiencing rapid changes in response to interacting climate and socioeconomic drivers. The North Slope Science Initiative (NSSI) is using scenarios as a tool to identify plausible, spatially explicit future states of resource extraction activities on the North Slope and adjacent seas through the year 2040. The objective of the scenarios process is to strategically assess research and monitoring needs on the North Slope. The participatory scenarios process involved stakeholder input (including Federal, State, local, academic, industry and non-profit representatives) to identify key drivers of change related to resource extraction activities on the North Slope. While climate change was identified as a key driver in the biophysical system, economic drivers related to oil and gas development were also important. Expert-reviewed informational materials were developed to help stakeholders obtain baseline knowledge and stimulate discussions about interactions between drivers, knowledge gaps and uncertainties. Map-based scenario products will allow mission-oriented agencies to jointly explore where to prioritize research investments and address risk in a complex, changing environment. Scenarios consider multidecadal timescales. However, tracking of indicator variables derived from scenarios can lead to important insights about the trajectory of the North Slope social-environmental system and inform management decisions to reduce risk on much shorter timescales. The inclusion of stakeholders helps provide a broad spectrum of expert viewpoints necessary for considering the range of plausible scenarios. A well-defined focal question, transparency in the participation process and continued outreach about the utility and limitations of scenarios are also important components of the scenarios process.

  7. The climatic water balance in an ecological context

    Science.gov (United States)

    Stephenson, N. L.

    2011-12-01

    Because the climatic water balance describes the seasonal interactions of energy (heat and solar radiation) and water in biologically meaningful ways, it provides a powerful tool for understanding and predicting the effects of climatic changes on the terrestrial biosphere. I begin with a brief overview of the definitions and interpretations of the biologically most important water balance parameters -- actual evapotranspiration (AET) and climatic water deficit (Deficit) -- and how the particular approach used to calculate these parameters depends both on the goals of the study and on the available climatic data. Some authors have attempted to represent aspects of the climatic water balance with indices based on annual potential evapotranspiration (PET) and precipitation (P), such at P/PET or PET - P. However, these and related indices do not reflect soil water dynamics, snow dynamics, or the seasonal interactions of energy and water, and therefore have no biological interpretation. Consequently, such indices are more poorly correlated with ecological patterns and processes than AET and Deficit. Of critical importance, the effects of changing energy and water supplies on the climatic water balance are nearly orthogonal. For example, a plant community growing on shallow soils on a shaded slope and one growing on deep soils on a sunward slope often may have the same amount of measured soil moisture available to them. However, the dynamics of energy and water that resulted in the identical soil moistures were fundamentally different (decreased evaporative demand on the shaded slope versus increased water supply on the deep soils); the associated differences in AET and Deficit will therefore result in different plant communities occupying the sites, in spite of identical soil moistures. In the context of climatic change, the orthogonal effects of energy and water mean that increasing precipitation cannot be expected to counteract the effects of increasing temperature

    When Australia's climate should not be definite barrier to the population reaching 30 million by 2050, it is recognised that our climate has limited the development of the nation over the past 200 years. Indeed in 1911, based on a comparison of the climate and development between the US and Australia. Griffith Taylor predicted that Australia's population would be 19 million at the end of the 20th century, which is a pretty good 90-year forecast. The climate constraint is not only due to much of the country being semi-arid with an annual rainfall below 400 millimetres, but also due to the large year-to-year variability of rainfall across the country

    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

In order to study the conditions of production and reception of information about climate change, a survey was conducted in four French secondary schools, in the 'Bas Rhin' and 'Nord' departments, and local political actors in each department were interviewed. The cross disciplinary analytical and methodological approach uses the tools of sociological inquiry, information science, and political science: questionnaires and interviews were conducted with members of the educational and governmental communities of each school and department, semiotic and discursive analyses of corpuses of documents were carried out, in order to characterize documents used by students and teachers at school or in more informal contexts; the nature and extent of the relations between the political contexts and school directives and programs were also discussed. This interdisciplinary approach, combining sociological, communicational, and political methods, was chosen in response to the hypothesis that three types of variables (social, communicational and political) contribute to the structuring and production of messages about climate change in schools. This report offers a contextualized overview of activities developed within the four secondary schools to help sensitize children to the risks associated with climate change. A study of the networks of individuals (teachers, staff, members of associations, etc.) created in and around the school environment is presented. The degree of involvement of these actors in climate change programs is analyzed, as it is related to their motives and objectives, to the school discipline taught, and to the position

    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

    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.

    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.

    This report deals with the main challenges of climate change, and attempts to answer some questions: what is the temperature increase foreseen by scientific experts? Who will be affected by the consequences of climate change? Are there technologies to reduce emissions? If yes, why are they not diffused? Is it justified to ask developing countries to do something? Are concurrence distortions a real problem? Which are the main sectors where emissions are to be reduced? Are tools developed at the international level efficient? What is the present assessment for the clean development mechanism? What can be thought of technological partnerships developed with the United States? Then, the report comments the present status of international discussions, proposes a brief assessment of the Kyoto protocol ten years after its implementation, and proposes some improvement pathways

    Full Text Available The Blue Mountains Adaptation Partnership (BMAP was established to increase climate change awareness, assess vulnerability to climate change, and develop science-based adaptation strategies for national forest lands in the Blue Mountains region of northeast Oregon and southeast Washington (USA. The BMAP process included (1 development of a science-management partnership, (2 a vulnerability assessment of the effects of climate change on natural resources and infrastructure, (3 development of adaptation options that will help reduce negative effects of climate change and assist the transition of biological systems and management to a changing climate, and (4 ongoing dialogue and activities related to climate change in the Blue Mountains region. This special issue of Climate Services describes social context and climate change vulnerability assessments for water use and infrastructure, vegetation, and riparian ecosystems of the Blue Mountains region, as well as adaptation options for natural resource management. This manuscript introduces the special issue, describing the management, biogeographic, and climatic context for the Blue Mountains region; the climate change vulnerability assessment and adaptation process used in BMAP; and the potential applications of the information described in the special issue. Although the institutional focus of information in the special issue is U.S. Forest Service lands (Malheur, Umatilla, and Wallowa-Whitman National Forests, the broader social context and adaptation options should be applicable to other lands throughout this region and the Pacific Northwest.

    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

    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 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.

    Fischer, G.; Shah, M.; Van Velthuizen, H.

    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

  20. Fair adaptation to climate change

    Paavola, Jouni; Adger, W. Neil

    2006-01-01

    This article identifies social justice dilemmas associated with the necessity to adapt to climate change, examines how they are currently addressed by the climate change regime, and proposes solutions to overcome prevailing gaps and ambiguities. 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.

    2009-07-01

    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.

    This case demonstrates a practical example from the city of Odense (DK) where new geological modeling techniques has been developed and used in the software GeoScene3D, to create a detailed voxel model of the anthropogenic layer. The voxel model has been combined with a regional hydrostratigraphic layer model. The case is part of a pilot project partly financed by VTU (Foundation for Development of Technology in the Danish Water Sector) and involves many different datatypes such as borehole information, geophysical data, human related elements (landfill, pipelines, basements, roadbeds etc). In the last few years, there has been increased focus on detailed geological modeling in urban areas. The models serve as important input to hydrological models. This focus is partly due to climate changes as high intensity rainfalls are seen more often than in the past, and water recharge is a topic too. In urban areas, this arises new challenges. There is a need of a high level of detailed geological knowledge for the uppermost zone of the soil, which typically are problematic due to practically limitations, especially when using geological layer models. Furthermore, to accommodate the need of a high detail, all relevant available data has to be used in the modeling process. Human activity has deeply changed the soil layers, e.g. by constructions as roadbeds, buildings with basements, pipelines, landfill etc. These elements can act as barriers or pathways regarding surface near groundwater flow and can attribute to local flooding or mobilization and transport of contaminants etc. A geological voxel model is built by small boxes (a voxel). Each box can contain several parameters, ex. lithology, transmissivity or contaminant concentration. Human related elements can be implemented using tools, which gives the modeler advanced options for making detailed small-scale models. This case demonstrates the workflow and the resulting geological model for the pilot area.

    The present collection of papers was compiled on the basis of research papers written by Estonian scientists during the United Nations Environment Programme and Global Environment Facility initiated climate change programme Country Case Study on Climate Change Impacts and Adaptations Assessments. The Estonian country case study was finally approved by UNEP/GEF in February 1996, practical work started in September. The priorities for Estonia in the study of global climate change impacts and adaptation have been in the following areas of interest: agriculture, water resources, forestry, the Baltic Sea and Estonian coast, also historical climate and socioeconomic background together with the biggest producer of greenhouse gases, the energy sector. Those areas have been studied more carefully during the one and half year period of the project

    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)

    Full Text Available Present brings several environmental problems for people. Many of these are closely related, but by far the most important problem is the climate change. 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 and air quality are closely related: through the policy measures implemented to mitigate these major environmental threats but also through the geophysical processes that drive them. We designed, developed and implemented a comprehensive regional air quality and climate modeling System to investigate future air quality in Europe taking into account the combined pressure of future climate change and long range transport. Using the prospective scenarios of the last generation of pathways for both climate change (emissions of well mixed greenhouse gases) and air pollutants, we can provide a quantitative view into the possible future air quality in Europe. We find that ozone pollution will decrease substantially under the most stringent scenario but the efforts of the air quality legislation will be adversely compensated by the penalty of global warming and long range transport for the business as usual scenario. For particulate matter, the projected reduction of emissions efficiently reduces exposure levels. (authors)

    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 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)

    In today's societies, the production base made up by the industrial fabric acts as an important link between the climate and its variations and our lifestyle. However, several decades of experience have often enabled us to minimise the impact of the weather and its fluctuations on activities, making the industrial sector out to be purely artificial and protected from climate impacts. Yet climate change leads us to challenge this assumption: if the industrial base is supposed to be impervious to the current climate, is this still the case in a context of climate change? In an attempt to answer this question, the Invulnerable project was launched, led by the Institute for Sustainable Development and International Relations (IDDRI) and bringing together scientific and industrial partners (Meteo-France, IPSL, CERFACS). Observing the availability of scientific resources on climate change, partly resulting from the modeling research coordinated by the IPCC, the idea was to work with industries to identify their vulnerabilities and to use these to define indicators for climatologists. These indicators are not chosen by scientists without consulting industries, but are in fact defined by these industries to ensure they correspond to their needs as closely as possible. The challenge is therefore to bring together scientists and industries and to catalyse a mutual understanding to ensure this discussion results in one or several indicators that are relevant to the activity in question and on which climatologists can work

    Full Text Available The World Climate Conference 2017 (COP 23 yielded the adoption of the first United Nations Framework Convention on Climate Change Gender Action Plan (GAP. This is a positive shift towards an integration of gender justice and human rights in the context of the UN Climate Action Plan. GAP necessitates importance granted to gender-equal climate policy and therefore, must be integrated into national climate action plans (programs. The first progress assessment will be conducted at COP 25 towards the end of 2019. However, while GAP recognizes women’s roles and importance with regard to climate change, it does not reach out beyond this. For instance, development policy measures that likewise play an important role have been excluded. In the Asia-Pacific the specific role of women as livelihood providers has received minimal attention and resultantly there has been little implementation of concrete measures. There are still many steps to be taken before deeper and more fundamental changes are reached.

    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. To understand the forcing behind natural rapid climate changes appears as important as to understand the role

    1994-01-01

    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

    Emissions of greenhouse gases (GHGs), especially from energy production and use, and their impact on global climate emerged as a major national issue in the United States during the 1980s. As a result, Congress directed the US Department of Energy (DOE) to ask the National Academy of Sciences and the National Academy of Engineering to assess the current state of research and development (R ampersand D) in the United States in alternative energy sources, and to suggest energy R ampersand D strategies involving roles for both the public and private sectors, should the government want to give priority to stabilizing atmospheric concentrations of GHGs. The findings and recommendations of the Committee on Alternative Energy Research and Development Strategies, appointed by the National Research Council in response to Congress's directive, are provided in this report and summarized in this chapter. The energy R ampersand D strategies and actions recommended by the committee are structured to facilitate prudent and decisive responses by the United States, despite uncertainties regarding the effects of GHGs on global climate. 96 refs., 4 figs., 17 tabs

    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

    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.

    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

    Adaptation has become an important issue in international and domestic discussions on climate change. Numerous terms and concepts have come into common usage as a result of IPCC reports, discussions in the context of the UNFCCC and dialogs by the climate community at large. This paper examines the key adaptation terms and concepts used by the climate change community and other institutions. Conflicts and contradictions are noted with the aim of sensitizing different bodies to the differences, but particularly the Parties to the Convention and experts participating in the IPCC. Given the need to promote a common understanding among various stakeholders and the potential financial implications of various definitions, it appears important for the IPCC and the UNFCCC to work toward common definitions, at least for a core set of terms and concepts

    Questions about global warming concern climate scientists and the general public alike. Specifically, what are the reliable surface temperature reconstructions over the past few centuries? And what are the best predictions of global temperature change the Earth might expect for the next century? Recent publications [National Research Council (NRC), 2006; Intergovernmental Panel on Climate Change (IPCC), 2007] permit these questions to be answered in a single informative illustration by assembling temperature reconstructions of the past thousand years with predictions for the next century. The result, shown in Figure 1, illustrates present and future warming in the context of natural variations in the past [see also Oldfield and Alverson, 2003]. To quote a Chinese proverb, “A picture's meaning can express ten thousand words.” Because it succinctly captures past inferences and future projections of climate, the illustration should be of interest to scientists, educators, policy makers, and the public.

    After a presentation of study objectives and scope, a first report outlines the actuality of climate change, describes predicted climate changes for the PACA region in terms of warming and decrease of precipitations. Regional social-economic challenges and sector impacts are also briefly described. The second report presents the adopted climate simulation parameters, and discusses results obtained in terms of temperature and of precipitations by 2030, 2050 and 2080 for the whole Great South East region. The third part proposes sector sheets which contain discussions of effects of climate change on the water resource, on biodiversity, on forest, on agriculture, on human health, on tourism, on energy, on building and transports, on natural risks. The next document is based on the previous ones. It discusses and comments the outcome of the first phase, the present situation of the region in terms of territorial dynamics and effects of climate change, and indicators of climate change. It also draws lessons from the prospective study which resulted in three scenarios for which a strategic assessment is proposed

    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

    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

    2012-04-01

    At the Meteorology & Climate Centre at University College Dublin, we are using the CLM-Community's COSMO-CLM Regional Climate Model (RCM) and the WRF RCM (developed at NCAR) to simulate the climate of Ireland at high spatial resolution. To address the issue of model uncertainty, a Multi-Model Ensemble (MME) approach is used. The ensemble method uses different RCMs, driven by several Global Climate Models (GCMs), to simulate climate change. Through the MME approach, the uncertainty in the RCM projections is quantified, enabling us to estimate the probability density function of predicted changes, and providing a measure of confidence in the predictions. The RCMs were validated by performing a 20-year simulation of the Irish climate (1981-2000), driven by ECMWF ERA-40 global re-analysis data, and comparing the output to observations. Results confirm that the output of the RCMs exhibit reasonable and realistic features as documented in the historical data record. Projections for the future Irish climate were generated by downscaling the Max Planck Institute's ECHAM5 GCM, the UK Met Office HadGEM2-ES GCM and the CGCM3.1 GCM from the Canadian Centre for Climate Modelling. Simulations were run for a reference period 1961-2000 and future period 2021-2060. The future climate was simulated using the A1B, A2, B1, RCP 4.5 & RCP 8.5 greenhouse gas emission scenarios. Results for the downscaled simulations show a substantial overall increase in precipitation and wind speed for the future winter months and a decrease during the summer months. The predicted annual change in temperature is approximately 1.1°C over Ireland. To date, all RCM projections are in general agreement, thus increasing our confidence in the robustness of the results.

    Full text: Full text: The potential for human impact on global climate arose out of an understanding developed in the 19th century of the physical conditions influencing global temperatures. In the past three decades, observations and improved understanding of climate processes have led to the conclusions that the planet has warmed, this warming has been primarily due to increases of atmospheric greenhouse gases and that this has been due to human activities. But our knowledge is incomplete. The management of the risks associated with future climate change demands improvement of the knowledge base. Specific areas for improvement include the: role of aerosols in the amelioration or otherwise of warming trends; potential instability of systems, e.g. the deglaciation of Greenland that could lead to rapid destabilisation of climate; response of biological systems to climate change, their phrenology, behaviour, genetics and dispersion; opportunities for cost-effective managed adaptation; and improved technologies for meeting the energy demands. Climate science has been characterised by a level of integration of disciplinary fields uncommon in other areas. Yet the nature of the climate system, its diverse impacts and the range of mitigation options suggests that while disciplinary endeavours need to continue, further integration is required. Policy development requires the exploration of options that respect the complexity of climate and its impacts but also the pluralistic aspirations of societies. The 21st century should be characterised by considered, inclusive and strategic policy development. For science to contribute to this process, much more attention is needed to the processes involved in the exchange of knowledge between the scientific community and those who develop public or private policy. A new engagement and shared understanding of the potential role of science in modern societies, particularly with respect to climate change, is an essential component of

    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.

  18. 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?”

  19. Three eras of climate change

    2006-10-15

    Climate change as a global challenge has evolved through a series of stages in the last few decades. We are now on the brink of a new era which will see the terms of the debate shift once again. The different eras are characterised by the scientific evidence, public perceptions, responses and engagement of different groups to address the problem. In the first era, from the late 1980s to 2000, climate change was seen as an “environmental” problem to do with prevention of future impacts on the planet's climate systems over the next fifty to hundred years, through reductions in emissions of greenhouse gases, known as “mitigation”. The second era can be said to have started around the turn of the millennium, with the recognition that there will be some unavoidable impacts from climate change in the near term (over the next decade or two). These impacts must be coped with through “adaptation”, as well as mitigation, to prevent much more severe and possibly catastrophic impacts in the longer term. It has become clear that many of the impacts of climate change in the near term are likely to fall on the poorest countries and communities. The third era, which we are just about to enter, will see the issue change from tackling an environmental or development problem to a question of “global justice”. It will engage with a much wider array of citizens from around the world than previous eras.

  20. Western water and climate change

    Science.gov (United States)

    Dettinger, Michael; Udall, Bradley; Georgakakos, Aris P.

    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.

  1. Market Strategies for Climate Change

    Kolk, A.; Pinkse, J. [Business School, University of Amsterdam, Amsterdam (Netherlands)

    2004-06-01

    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.

    In this document the authors indicate that some level of adaptation will be required as climate change affects our lives. They narrowed their examination to three sectors of Canadian society: human health, agriculture, and northern communities and infrastructure. Within each sector they discussed the policy research needs and the adaptation problems to be expected. Uncertainties remain concerning the magnitude of climate change, its timing and consequences, and further research is required to reduce the uncertainties. Canada presents certain vulnerabilities, and to enhance and improve the resilience of the population toward climate change, some adaptation measures must be put in place to reduce the vulnerabilities. Confidence will come as a by-product of the leadership required to bring about the required adaptation measures, and cooperation is a must between all levels of government, the private sector and society to reach agreement.

    Faced with the mounting evidence of the harmful effects of climate change, the European Union is convinced that the world must take urgent action to tackle the problem. That is why the EU has been at the forefront of international efforts to deal with climate change for well over a decade. The EU is convinced that the status quo is simply not an option. Without urgent, concerted action, the problem will continue to get worse with potentially disastrous consequences. That is why the European Union has consistently taken the lead in international moves to tackle climate change and why it will continue to develop this strategy for as long as it takes to guarantee a world for ourselves and our children where everyone can grow, breathe and live in safety

    The paper consists of the author's personal remarks on a political assessment of climate change policy in the United States. The author focuses on four major political forces; environmental organisations, the Clinton-Gore administration, the U.S. senate and the business community. The author considers that much of the climate change debate is scaremongering by the environmentalists with little scientific basis. There is a need for business to present its case better if it is to avoid economically damaging, but unjustified environmental regulations.

    It is clear that the public health community is concerned about the human health impacts of climate change, but are we inadvertently underestimating the scope of the problem and obfuscating potentially useful interventions by using a narrow intellectual frame in our discussions with policy makers? If we take a more holistic approach, we see that the public health impacts of climate change are only one subset of the enormous public health impacts of fossil fuel burning. This broader perspective can provide a more accurate and comprehensive assessment that is more useful for decision making in public policy settings.

  13. Climate change-related migration and infectious disease.

    2015-01-01

    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.

  14. Sustain : the climate change challenge

    International Nuclear Information System (INIS)

    1998-01-01

    This special report on climate change and greenhouse gas emissions focused on widely held current opinions which indicate that average global surface temperatures are increasing. The potential consequences of climate change can include rising sea levels, drought storms, disease, and mass migration of people. While the global climate change theory is widely accepted, the report warns that there are still many uncertainties about how climate change occurs and what processes can offset human-caused emissions. Canada produces about 2 per cent of global greenhouse gas emissions. Carbon dioxide comprises 80 per cent of Canada's total emissions. It is well known that Canadians place a heavy demand on energy to heat and light their homes because of the northern climate, and on transportation fuels to move people, goods and services across vast distances. With the Kyoto Protocol of December 1997, developed countries agreed to legally binding greenhouse gas emission reductions of at least five per cent by 2008 to 2012. Canada agreed to a six per cent reduction below 1990 levels by 2010. Although Canada signed the Kyoto Protocol, it does not intend to ratify it until an implementation strategy has been developed with broad support. The goal is to develop a strategy by 1999. The oil and gas industry has in general improved its efficiency and reduced emissions on a per unit of production basis by installing new equipment and new operating practices that reduce greenhouse gas emissions to the atmosphere, and improve energy efficiency. The industry is conscious of its responsibility, and while not fully in agreement with the environmental doomsayers, it is prepared to take proactive actions now, albeit on a voluntary basis. What the industry wants is a balance between environmental and economic responsibility. E missions trading' and 'joint implementation' are seen as two important tools to tackle climate change on a global basis. 4 figs

    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

    1999-08-09

    In the four years since the IPCC stated that 'the balance of evidence suggests a discernible human influence on global climate', evidence for anomalous warming has become more compelling, and as a result scientists have become more concerned that human-induced climate change has already arrived. The article summarises recent extra evidence on global temperatures, carbon dioxide measurements, ice shelf breakup, coral bleaching, unstable climates and improved climate models. At the time of the Kyoto conference, the US became keen on the idea that enhancing forest and soil carbon sequestration was a good way to offset emissions reduction targets. Congress is however under the opinion on that the Kyoto protocol presents a threat to the US economy, and senate is very unlikely to ratify the protocol during the Clinton Administration. The debate as to whether the US government should mandate major emission reduction or wait for more scientific certainty may continue for a number of years, but, growing concern of scientists and the public for the harmful effects of climate change may cause a change. 4 figs., 8 photos.

    The authors address the issue of adaptation to climate change. They first address the physical aspects related to this issue: scenarios of temperature evolution, main possible impacts. Then, they address the social impacts related to climate risks, and the adaptation strategies which aim at reducing the exposure and vulnerability of human societies, or at increasing their resilience. Some examples of losses of human lives and of economic damages due to recent catastrophes related to climate change are evoked. The authors address the international framework, the emergence of an international regime on climate, the quite recent emergence of adaptation within international negotiations in 2001, the emergence of the idea of a support to developing countries. National and local policies are presented in the next chapter (in the European Union, the Netherlands which are faced with the issue of sea level rise, programs in developing countries) and their limitations are also outlined. The next chapter addresses the adaptation actions performed by private actors (enterprises, households, associations, civil society, and so on) with example of vulnerability, and adaptation opportunities and possibilities in some specific sectors. The last chapter presents a typology of actions of adaptation, indicators of adaptation to climate change, and examples of mistaken adaptation

    Full Text Available For many species the threats of climate change occur in a context of multiple existing threats. Given the current focus of global change ecology in identifying and understanding species vulnerable to climate change, we performed a global analysis to characterize the multi-threat context for species threatened by climate change. Utilizing 30,053 species from the International Union for Conservation of Nature’s (IUCN Red List of Threatened Species, we sought to evaluate if species threatened by climate change are more likely threatened by a greater number of non-climatic threats than species not threatened by climate change. Our results show that species threatened by climate change are generally impacted by 21% more non-climatic threats than species not threatened by climate change. Across all species, this pattern is related to IUCN risk status, where endangered species threatened by climate change face 33% more non-climatic threats than endangered species not threatened by climate change. With the clear challenges of assessing current and projected impacts of climate change on species and ecosystems, research often requires reductionist approaches that result in downplaying this multi-threat context. This cautionary note bears relevance beyond climate change threatened species as we also found other (but not all anthropogenic threats are also similarly associated with more threats. Our findings serve as a reminder that ecological research should seriously consider these potential threat interactions, especially for species under elevated conservation concern.

    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.

  1. 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.

    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)

Methodologically the research was a descriptive study with a field design. The population was constituted by: (2 managers and (35 teachers from the different institutions that make up the NER. For the information a questionnaire was made with different alternative of selection, obtaining the following results: According to the indicator structural dimension, the 58.3% of respondents express that the manager never posed a system of interrelationships among his personal or staff. Related with the indicator responsibility, 61.6% said that they don’t feel motivate and don’t get involved in the work of the institution. With regard to the indicator reward, 55% said they are never rewarded or incentivized by the management of the institution. Concerning with the indicator relations, 61.3% of respondents said that there is an absence of a pleasant work environment, and respect for teachers; by the same way, 59% of respondents stated that conflicts are never resolved in a better way. In conclusion, most of teacher and managers of the NER 196 do not implement effectively dimensions of organizational climate, they also don`t contribute to the achievement of corporate goals successfully.

  4. 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

    Many researchers are working on all the separate parts of the climate problem. The objective of integrated assessment is to put the results from this work together in order to look carefully at the big picture so as to: (1) keep a proper sense of perspective about the problem, since climate change will occur in the presence of many other natural and human changes; (2) develop the understanding necessary to support informed decision making by many different key public and private actors around the world; and (3) assure that the type and mix of climate-related research that is undertaken will be as useful as possible to decisions makers in both the near and long term. This paper outlines a set of design guidelines for formulating integrated assessment programs and projects and then outlines some of the current problems and opportunities. Selected points are illustrated by drawing on results from the integrated assessment research now in progress at Carnegie Mellon University

  8. High Resolution Modeling of Hurricanes in a Climate Context

    Knutson, T. R.

    2007-12-01

    Modeling of tropical cyclone activity in a climate context initially focused on simulation of relatively weak tropical storm-like disturbances as resolved by coarse grid (200 km) global models. As computing power has increased, multi-year simulations with global models of grid spacing 20-30 km have become feasible. Increased resolution also allowed for simulation storms of increasing intensity, and some global models generate storms of hurricane strength, depending on their resolution and other factors, although detailed hurricane structure is not simulated realistically. Results from some recent high resolution global model studies are reviewed. An alternative for hurricane simulation is regional downscaling. An early approach was to embed an operational (GFDL) hurricane prediction model within a global model solution, either for 5-day case studies of particular model storm cases, or for "idealized experiments" where an initial vortex is inserted into an idealized environments derived from global model statistics. Using this approach, hurricanes up to category five intensity can be simulated, owing to the model's relatively high resolution (9 km grid) and refined physics. Variants on this approach have been used to provide modeling support for theoretical predictions that greenhouse warming will increase the maximum intensities of hurricanes. These modeling studies also simulate increased hurricane rainfall rates in a warmer climate. The studies do not address hurricane frequency issues, and vertical shear is neglected in the idealized studies. A recent development is the use of regional model dynamical downscaling for extended (e.g., season-length) integrations of hurricane activity. In a study for the Atlantic basin, a non-hydrostatic model with grid spacing of 18km is run without convective parameterization, but with internal spectral nudging toward observed large-scale (basin wavenumbers 0-2) atmospheric conditions from reanalyses. Using this approach, our

  11. How Does The Climate Change?

    2011-12-01

    In 1997, maximum temperature in SE Australia shifted up by 0.8°C at pH0impact indicators: baumé levels in winegrapes shift >21 days earlier from 1998, streamflow records decrease by 30-70% from 1997 and annual mean forest fire danger index increased by 38% from 1997. Despite catastrophic fires killing 178 people in early 2009, the public remains unaware of this large change in their exposure. When regional temperature was separated into internally and externally forced components, the latter component was found to warm in two steps, in 1968-73 and 1997. These dates coincide with shifts in zonal mean temperature (24-44S; Figure 1). Climate model output shows similar step and trend behavior. Tests run on zonal, hemispheric and global mean temperature observations found shifts in all regions. 1997 marks a shift in global temperature of 0.3°C at pH0ocean heat content. The prevailing paradigm for how climate variables change is signal-noise construct combining a smooth signal with variations caused by internal climate variability. There seems to be no sound theoretical basis for this assumption. On the contrary, complex system behavior would suggest non-linear responses to externally forced change, especially at the regional scale. Some of our most basic assumptions about how climate changes may need to be re-examined.

  15. Emergency Managers Confront Climate Change

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available Emergency managers will have to deal with the impending, uncertain, and possibly extreme effects of climate change. Yet, many emergency managers are not aware of the full range of possible effects, and they are unsure of their place in the effort to plan for, adapt to, and cope with those effects. This may partly reflect emergency mangers’ reluctance to get caught up in the rancorous—and politically-charged—debate about climate change, but it mostly is due to the worldview shared by most emergency managers. We focus on: extreme events; acute vs. chronic hazards (floods vs. droughts; a shorter event horizon (5 years vs. 75–100 years; and a shorter planning and operational cycle. This paper explores the important intersection of emergency management, environmental management, and climate change mitigation and adaptation. It examines the different definitions of terms common to all three fields, the overlapping strategies used in all three fields, and the best means of collaboration and mutual re-enforcement among the three to confront and solve the many possible futures that we may face in the climate change world.

    The rate of global warming has accelerated over the past 50 years. Increasing surface temperature is melting glaciers and raising the sea level. More flooding, droughts, hurricanes, and heat waves are being reported. Accelerated changes in climate are already affecting human health, in part by altering the epidemiology of climate-sensitive pathogens. In particular, climate change may alter the incidence and severity of respiratory infections by affecting vectors and host immune responses. Certain respiratory infections, such as avian influenza and coccidioidomycosis, are occurring in locations previously unaffected, apparently because of global warming. Young children and older adults appear to be particularly vulnerable to rapid fluctuations in ambient temperature. For example, an increase in the incidence in childhood pneumonia in Australia has been associated with sharp temperature drops from one day to the next. Extreme weather events, such as heat waves, floods, major storms, drought, and wildfires, are also believed to change the incidence of respiratory infections. An outbreak of aspergillosis among Japanese survivors of the 2011 tsunami is one such well-documented example. Changes in temperature, precipitation, relative humidity, and air pollution influence viral activity and transmission. For example, in early 2000, an outbreak of Hantavirus respiratory disease was linked to a local increase in the rodent population, which in turn was attributed to a two- to threefold increase in rainfall before the outbreak. Climate-sensitive respiratory pathogens present challenges to respiratory health that may be far greater in the foreseeable future.

    The production and consumption of energy contributes to the concentration of greenhouse gases in the atmosphere and is the focus of other environmental concerns as well. Yet the use of energy contributes to worldwide economic growth and development. If we are to achieve environmentally sound economic growth, we must develop and deploy energy technologies that contribute to global stewardship. The Department of Energy carries out an aggressive scientific research program to address some of the key uncertainties associated with the climate change issue. Of course, research simply to study the science of global climate change is not enough. At the heart of any regime of cost-effective actions to address the possibility of global climate change will be a panoply of new technologies-technologies both to provide the services we demand and to use energy more efficiently than in the past. These, too, are important areas of responsibility for the Department. This report is a brief description of the Department's activities in scientific research, technology development, policy studies, and international cooperation that are directly related to or have some bearing on the issue of global climate change

    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.

  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.

  8. Climate modelling, uncertainty and responses to predictions of change

    Henderson-Sellers, A.

    1996-01-01

    Article 4.1(F) of the Framework Convention on Climate Change commits all parties to take climate change considerations into account, to the extent feasible, in relevant social, economic and environmental policies and actions and to employ methods such as impact assessments to minimize adverse effects of climate change. This could be achieved by, inter alia, incorporating climate change risk assessment into development planning processes, i.e. relating climatic change to issues of habitability and sustainability. Adaptation is an ubiquitous and beneficial natural and human strategy. Future adaptation (adjustment) to climate is inevitable at the least to decrease the vulnerability to current climatic impacts. An urgent issue is the mismatch between the predictions of global climatic change and the need for information on local to regional change in order to develop adaptation strategies. Mitigation efforts are essential since the more successful mitigation activities are, the less need there will be for adaptation responses. And, mitigation responses can be global (e.g. a uniform percentage reduction in greenhouse gas emissions) while adaptation responses will be local to regional in character and therefore depend upon confident predictions of regional climatic change. The dilemma facing policymakers is that scientists have considerable confidence in likely global climatic changes but virtually zero confidence in regional changes. Mitigation and adaptation strategies relevant to climatic change can most usefully be developed in the context of sound understanding of climate, especially the near-surface continental climate, permitting discussion of societally relevant issues. But, climate models can't yet deliver this type of regionally and locationally specific prediction and some aspects of current research even seem to indicate increased uncertainty. These topics are explored in this paper using the specific example of the prediction of land-surface climate changes

  9. Climate Change and Intertidal Wetlands

    2013-03-01

    Full Text Available Intertidal wetlands are recognised for the provision of a range of valued ecosystem services. The two major categories of intertidal wetlands discussed in this contribution are saltmarshes and mangrove forests. Intertidal wetlands are under threat from a range of anthropogenic causes, some site-specific, others acting globally. Globally acting factors include climate change and its driving cause—the increasing atmospheric concentrations of greenhouse gases. One direct consequence of climate change will be global sea level rise due to thermal expansion of the oceans, and, in the longer term, the melting of ice caps and glaciers. The relative sea level rise experienced at any one locality will be affected by a range of factors, as will the response of intertidal wetlands to the change in sea level. If relative sea level is rising and sedimentation within intertidal wetlands does not keep pace, then there will be loss of intertidal wetlands from the seaward edge, with survival of the ecosystems only possible if they can retreat inland. When retreat is not possible, the wetland area will decline in response to the “squeeze” experienced. Any changes to intertidal wetland vegetation, as a consequence of climate change, will have flow on effects to biota, while changes to biota will affect intertidal vegetation. Wetland biota may respond to climate change by shifting in distribution and abundance landward, evolving or becoming extinct. In addition, impacts from ocean acidification and warming are predicted to affect the fertilisation, larval development, growth and survival of intertidal wetland biota including macroinvertebrates, such as molluscs and crabs, and vertebrates such as fish and potentially birds. The capacity of organisms to move and adapt will depend on their life history characteristics, phenotypic plasticity, genetic variability, inheritability of adaptive characteristics, and the predicted rates of environmental change.

    The global warming debate has neglected and thus underestimated the importance of technical change in considering reduction in greenhouse gases and adaptation to climate change. Relevant quantitative cases of long-run technical change during the past 100 years are presented in computing, communications, transport, energy, and agriculture. A noteworthy technological trajectory is that of decarbonization, or decreasing carbon intensity of primary energy. If human societies have not yet reached the end of the history of technology, the cost structure for mitigation and adaptation changes could be cheap. (Author)

    2016-01-01

    Anthropogenic climate change amounts to a rapidly approaching, “new” stressor in the Sacramento–San Joaquin Delta system. In response to California’s extreme natural hydroclimatic variability, complex water-management systems have been developed, even as the Delta’s natural ecosystems have been largely devastated. Climate change is projected to challenge these management and ecological systems in different ways that are characterized by different levels of uncertainty. For example, there is high certainty that climate will warm by about 2°C more (than late-20th-century averages) by mid-century and about 4°C by end of century, if greenhouse-gas emissions continue their current rates of acceleration. Future precipitation changes are much less certain, with as many climate models projecting wetter conditions as drier. However, the same projections agree that precipitation will be more intense when storms do arrive, even as more dry days will separate storms. Warmer temperatures will likely enhance evaporative demands and raise water temperatures. Consequently, climate change is projected to yield both more extreme flood risks and greater drought risks. Sea level rise (SLR) during the 20th century was about 22cm, and is projected to increase by at least 3-fold this century. SLR together with land subsidence threatens the Delta with greater vulnerabilities to inundation and salinity intrusion. Effects on the Delta ecosystem that are traceable to warming include SLR, reduced snowpack, earlier snowmelt and larger storm-driven streamflows, warmer and longer summers, warmer summer water temperatures, and water-quality changes. These changes and their uncertainties will challenge the operations of water projects and uses throughout the Delta’s watershed and delivery areas. Although the effects of climate change on Delta ecosystems may be profound, the end results are difficult to predict, except that native species will fare worse than invaders. Successful

  15. Is Ignorance of Climate Change Culpable?

    Science.gov (United States)

    Robichaud, Philip

    2017-10-01

    Sometimes ignorance is an excuse. If an agent did not know and could not have known that her action would realize some bad outcome, then it is plausible to maintain that she is not to blame for realizing that outcome, even when the act that leads to this outcome is wrong. This general thought can be brought to bear in the context of climate change insofar as we think (a) that the actions of individual agents play some role in realizing climate harms and (b) that these actions are apt targets for being considered right or wrong. Are agents who are ignorant about climate change and the way their actions contribute to it excused because of their ignorance, or is their ignorance culpable? In this paper I examine these questions from the perspective of recent developments in the theories of responsibility for ignorant action and characterize their verdicts. After developing some objections to existing attempts to explore these questions, I characterize two influential theories of moral responsibility and discuss their implications for three different types of ignorance about climate change. I conclude with some recommendations for how we should react to the face of the theories' conflicting verdicts. The answer to the question posed in the title, then, is: "Well, it's complicated."

    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

  18. Climate change adaptation in regulated water utilities

    Vicuna, S.; Melo, O.; Harou, J. J.; Characklis, G. W.; Ricalde, I.

    2017-12-01

    Concern about climate change impacts on water supply systems has grown in recent years. However, there are still few examples of pro-active interventions (e.g. infrastructure investment or policy changes) meant to address plausible future changes. Deep uncertainty associated with climate impacts, future demands, and regulatory constraints might explain why utility planning in a range of contexts doesn't explicitly consider climate change scenarios and potential adaptive responses. Given the importance of water supplies for economic development and the cost and longevity of many water infrastructure investments, large urban water supply systems could suffer from lack of pro-active climate change adaptation. Water utilities need to balance the potential for high regret stranded assets on the one side, with insufficient supplies leading to potentially severe socio-economic, political and environmental failures on the other, and need to deal with a range of interests and constraints. This work presents initial findings from a project looking at how cities in Chile, the US and the UK are developing regulatory frameworks that incorporate utility planning under uncertainty. Considering for example the city of Santiago, Chile, recent studies have shown that although high scarcity cost scenarios are plausible, pre-emptive investment to guard from possible water supply failures is still remote and not accommodated by current planning practice. A first goal of the project is to compare and contrast regulatory approaches to utility risks considering climate change adaptation measures. Subsequently we plan to develop and propose a custom approach for the city of Santiago based on lessons learned from other contexts. The methodological approach combines institutional assessment of water supply regulatory frameworks with simulation-based decision-making under uncertainty approaches. Here we present initial work comparing the regulatory frameworks in Chile, UK and USA evaluating

    Climate change and associated changes in streamflow may alter riparian habitats substantially in coming decades. Riparian restoration provides opportunities to respond proactively to projected climate change effects, increase riparian ecosystem resilience to climate change, and simultaneously address effects of both climate change and other human disturbances. However, climate change may alter which restoration methods are most effective and which restoration goals can be achieved. Incorporating climate change into riparian restoration planning and design is critical to long-term restoration of desired community composition and ecosystem services. In this review, we discuss and provide examples of how climate change might be incorporated into restoration planning at the key stages of assessing the project context, establishing restoration goals and design criteria, evaluating design alternatives, and monitoring restoration outcomes. Restoration planners have access to numerous tools to predict future climate, streamflow, and riparian ecology at restoration sites. Planners can use those predictions to assess which species or ecosystem services will be most vulnerable under future conditions, and which sites will be most suitable for restoration. To accommodate future climate and streamflow change, planners may need to adjust methods for planting, invasive species control, channel and floodplain reconstruction, and water management. Given the considerable uncertainty in future climate and streamflow projections, riparian ecological responses, and effects on restoration outcomes, planners will need to consider multiple potential future scenarios, implement a variety of restoration methods, design projects with flexibility to adjust to future conditions, and plan to respond adaptively to unexpected change.

  3. The European Climate Change Programme. EU Action against Climate Change

    2006-01-01

    The European Union has long been committed to international efforts to tackle climate change and felt the duty to set an example through robust policy-making at home. At European level a comprehensive package of policy measures to reduce greenhouse gas emissions has been initiated through the European Climate Change Programme (ECCP). Each of the 25 EU Member States has also put in place its own domestic actions that build on the ECCP measures or complement them. The European Commission established the ECCP in 2000 to help identify the most environmentally effective and most cost-effective policies and measures that can be taken at European level to cut greenhouse gas emissions. The immediate goal is to help ensure that the EU meets its target for reducing emissions under the Kyoto Protocol. This requires the 15 countries that were EU members before 2004 to cut their combined emissions of greenhouse gases to 8% below the 1990 level by 2012

    The upcoming UN conference on climate change in Durban, South Africa throws a spotlight on African climate policy. As part of a knowledge-sharing initiative in Southern Africa, we assessed parliamentarians' needs for more information on climate threats and responses, and ways to improve their capabilities as key stakeholders influencing national and global decisionmaking. Funded by the UK Foreign and Commonwealth Office and partnered with the Association of European Parliamentarians with Africa (AWEPA), IIED worked with parliamentarians in the Southern Africa Customs Union (SACU) — Botswana, Lesotho, Namibia, South Africa and Swaziland — through interviews, literature surveys, field trips and workshops. Similar studies in Malawi and Scotland also fed into this project.

    Climate and weather events affect energy demand in most economic sectors. Linear relationships exist between consumption and heating degree days, and peak electricity demand increases significantly during heat waves. The relative magnitudes of demand changes for a two times carbon dioxide concentration scenario are tabulated, illustrating heating degree days and cooling degree days for 5 Prairie locations. Irrigation, water management, crop seeding and harvesting and weed control are examples of climate-dependent agricultural activities involving significant energy use. The variability of summer season liquid fuel use in the agricultural sector in the Prairie provinces from 1984-1989 shows a relationship between agricultural energy use and regional climate fluctuations. 4 refs., 2 figs., 1 tab

    The Parallel Climate Model (PCM) has been used in the Accelerated Climate Prediction Initiative (ACPI) Program to simulate the global climate response to projected CO2, sulfate, and other greenhouse gas forcing under a business-as-usual emissions scenario during the 21st century. In these runs, the oceans were initialized to 1995 conditions by a group from the Scripps Institution of Oceanography and other institutions. An ensemble of three model runs was then carried out to the year 2099 using the projected forcing. Atmospheric data from these runs were saved at 6-hourly intervals (hourly for certain critical fields) to support the ACPI objective of accurately modeling hydrological cycles over the western U.S. It is shown that the initialization to 1995 conditions partly removes the un-forced oceanic temperature and salinity drifts that occurred in the standard 20th century integration. The ACPI runs show a global surface temperature increase of 3-8C over northern high-latitudes by the end of the 21st century, and 1-2C over the oceans. This is generally within ±0.1C of model runs without the 1995 ocean initialization. The exception is in the Antarctic circumpolar ocean where surface air temperature is cooler in the ACPI run; however the ensemble scatter is large in this region. Although the difference in climate at the end of the 21st century is minimal between the ACPI runs and traditionally spun up runs, it might be larger for CGCMs with higher climate sensitivity or larger ocean drifts. Our results suggest that the effect of small errors in the oceans (such as those associated with climate drifts) on CGCM-simulated climate changes for the next 50-100 years may be negligible

    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

  9. Clean coal technologies and global climate change

    International Nuclear Information System (INIS)

    Long, R.S.

    1993-01-01

    The role for Clean Coal Technologies is discussed in the context of the global climate change debate. Global climate change is, of course as the name implies, a global issue. This clearly distinguishes this issue from acid rain or ozone non-attainment, which are regional in nature. Therefore, the issue requires a global perspective, one that looks at the issue not just from a US policy standpoint but from an international policy view. This includes the positions of other individual nations, trading blocks, common interest groups, and the evolving United Nations bureaucracy. It is assumed that as the global economy continues to grow, energy demand will also grow. With growth in economic activity and energy use, will come growth in worldwide greenhouse gas emissions, including growth in carbon dioxide (CO 2 ) emissions. Much of this growth will occur in developing economies which intend to fuel their growth with coal-fired power, especially China and India. Two basic premises which set out the boundaries of this topic are presented. First, there is the premise that global climate change is occurring, or is about to occur, and that governments must do something to mitigate the causes of climate change. Although this premise is highly rebuttable, and not based on scientific certainty, political science has driven it to the forefront of the debate. Second is the premise that advanced combustion CCTs, with their higher efficiencies, will result in lower CO 2 emissions, and hence lessen any contribution of greater coal use to potential global climate change. This promise is demonstrably true. This discussion focuses on recent and emerging public sector policy actions, which may in large part establish a new framework in which the private sector will find new challenges and new opportunities

    Climate change poses a serious challenge to social and economic development. Developing countries are particularly vulnerable because their economies are generally more dependent on climate-sensitive natural resources, and because they are less able to cope with the impacts of climate change. How development occurs has implications, in turn, for climate change and for the vulnerability of societies to its impacts. Climate change adaptation needs to be brought into the mainstream of economic policies, development projects, and international aid efforts. Considerable analytical work has been done on how development can be made climate-friendly in terms of helping reduce greenhouse gas emissions which cause climate change, although implementation remains a challenge. Much less attention has been paid to how development can be made more resilient to the impacts of climate change. In a narrow engineering sense, this could involve taking climate changes into account in the siting and design of bridges and other infrastructure. At a policy level, it could involve considering the implications of climate change on a variety of development activities including poverty reduction, sectoral development, and natural resource management. Bridging the gap between the climate change adaptation and development communities, however, is not easy. The two communities have different priorities, often operate on different time and space scales, and do not necessarily 'speak the same language'. Specific information is therefore needed on the significance of climate change for development activities along with operational guidance on how best to adapt to its impacts, within the context of other pressing social priorities. This Policy Brief looks at how far current development policies and programmes are taking climate change risks into account, as well as at ways to improve the 'mainstreaming' of adaptation to climate change in development planning and assistance

    2008-10-01

    Asia's role in global climate change has evolved significantly from the time when the Kyoto Protocol was being negotiated. Emissions of carbon dioxide, the principal greenhouse gas, from energy use in Asian countries now exceed those from the European Union or North America. Three of the top five emitters-China, India, and Japan, are Asian countries. Any meaningful global effort to address global climate change requires the active cooperation of these and other large Asian countries, if it is to succeed. Issues of equity between countries, within countries, and between generations, need to be tackled. Some quantitative current and historic data to illustrate the difficulties involved are provided, and one approach to making progress is suggested.

    The 2007 Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) concludes: "Warming in the climate system is unequivocal." Without the contribution of Physics to climate science over many decades, such a statement would not have been possible. Experimental physics enables us to read climate archives such as polar ice cores and so provides the context for the current changes. For example, today the concentration of CO2 in the atmosphere, the second most important greenhouse gas, is 28% higher than any time during the last 800,000 years. Classical fluid mechanics and numerical mathematics are the basis of climate models from which estimates of future climate change are obtained. But major instabilities and surprises in the Earth System are still unknown. These are also to be considered when the climatic consequences of proposals for geo-engineering are estimated. Only Physics will permit us to further improve our understanding in order to provide the foundation for policy decisions facing the...

    The manifestations of climate change can result in humanitarian impacts that reverse progress in poverty- reduction, create shortages of food and resources, lead to migration, and ultimately result in civil violence and conflict. Within the continent of Africa, we have found that environmentally-related variables are either the cause or the confounding factor for over 80% of the civil violence events during the last 10 years. Using predictive climate models and land-use data, we are able to identify populations in Africa that are likely to experience the most severe climate-related shocks. Through geospatial analysis, we are able to overlay these areas of high risk with assessments of both the local population's resiliency and the region's capacity to respond to climate shocks should they occur. The net result of the analysis is the identification of locations that are becoming particularly vulnerable to future civil violence events (vulnerability hotspots) as a result of the manifestations of climate change. For each population group, over 600 social, economic, political, and environmental indicators are integrated statistically to measures the vulnerability of African populations to environmental change. The indicator time-series are filtered for data availability and redundancy, broadly ordered into four categories (social, political, economic and environmental), standardized and normalized. Within each category, the dominant modes of variability are isolated by principal component analysis and the loadings of each component for each variable are used to devise composite index scores. Comparisons of past vulnerability with known environmentally-related conflicts demonstrates the role that such vulnerability hotspot maps can play in evaluating both the potential for, and the significance of, environmentally-related civil violence events. Furthermore, the analysis reveals the major variables that are responsible for the population's vulnerability and therefore

    1997-01-01

    The idea that an increase in greenhouse gases will cause the global average temperature to rise slowly over the next decades was discussed. Studies of ice core from Greenland have shown that in the past climate shifts seem to have happened quickly. Some scientists fear that increasingly frequent extreme weather events could be a sign that the climate system is nearing its threshold and a rapid climate flip may be just ahead. In the case of global climatic system, the danger is that stresses from greenhouse gas effects are pushing the present system over the threshold where it must flip into a new warmer system that will be stable, but different from the climate on which our agriculture, economy, settlements and lives depend. 4 refs

    Full text: Full text: The main conclusions of the IPCC Working Group I assessment of the physical science of climate change, from the Fourth IPCC Assessment, will be presented, along with the evidence supporting these conclusions. These conclusions include: Global atmospheric concentrations of carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values determined from ice cores spanning many thousands of years. The global increases in carbon dioxide concentration are due primarily to fossil fuel use and land use change, while those of methane and nitrous oxide are primarily due to agriculture; The understanding of anthropogenic warming and cooling influences on climate has improved since the Third Assessment Report, leading to very high confidence that the global average net effect of human activities since 1750 has been one of warming, with a radiative forcing of +1.6 [+0.6 to +2.4] Wm-2; Warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level; At continental, regional and ocean basin scales, numerous long-term changes in climate have been observed. These include changes in arctic temperatures and ice, widespread changes in precipitation amounts, ocean salinity, wind patterns and aspects of extreme weather including droughts, heavy precipitation, heat waves and the intensity of tropical cyclones. Palaeo-climatic information supports the interpretation that the warmth of the last half-century is unusual in at least the previous 1,300 years; Most of the observed increase in global average temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations; Discernible human influences now extend to other aspects of climate, including ocean warming, continental

  16. Climate change mitigation in China

    China has been experiencing great economic development and fast urbanisation since its reforms and opening-up policy in 1978. However, these changes are reliant on consumption of primary energy, especially coal, characterised by high pollution and low efficiency. China's greenhouse gas (GHG) emissions, with carbon dioxide (CO{sub 2}) being the most significant contributor, have also been increasing rapidly in the past three decades. Responding to both domestic challenges and international pressure regarding energy, climate change and environment, the Chinese government has made a point of addressing climate change since the early 2000s. This thesis provides a comprehensive analysis of China's CO{sub 2} emissions and policy instruments for mitigating climate change. In the analysis, China's CO{sub 2} emissions in recent decades were reviewed and the Environmental Kuznets Curve (EKC) hypothesis examined. Using the mostly frequently studied macroeconomic factors and time-series data for the period of 1980-2008, the existence of an EKC relationship between CO{sub 2} per capita and GDP per capita was verified. However, China's CO{sub 2} emissions will continue to grow over coming decades and the turning point in overall CO{sub 2} emissions will appear in 2078 according to a crude projection. More importantly, CO{sub 2} emissions will not spontaneously decrease if China continues to develop its economy without mitigating climate change. On the other hand, CO{sub 2} emissions could start to decrease if substantial efforts are made. China's present mitigation target, i.e. to reduce CO{sub 2} emissions per unit of GDP by 40-45 % by 2020 compared with the 2005 level, was then evaluated. Three business-as-usual (BAU) scenarios were developed and compared with the level of emissions according to the mitigation target. The calculations indicated that decreasing the CO{sub 2} intensity of GDP by 40-45 % by 2020 is a challenging but hopeful target. To

    Full Text Available After 2003, another hot summer took place in Western and Central Europe in 2015. In this study, we compare the characteristics of the two major heat waves of these two summers and their effect on the heat related mortality. The analysis is performed with focus on South-West Germany (Baden–Württemberg. With an additional mean summer mortality of +7.9% (2003 and +5.8% (2015 both years mark the top-two records of the summer mortality in the period 1968–2015. In each summer, one major heat wave contributed strongly to the excess summer mortality: In August 2003, daily mortality reached anomalies of +70% and in July 2015 maximum deviations of +56% were observed. The August 2003 heat wave was very long-lasting and characterized by exceptional high maximum and minimum temperatures. In July 2015, temperatures were slightly lower than in 2003, however, the high air humidity during the day and night, lead to comparable heat loads. Furthermore, the heat wave occurred earlier during the summer, when the population was less acclimated to heat stress. Using regional climate models we project an increasing probability for future 2003- and 2015-like heat waves already in the near future (2021–2050, with a 2015-like event occurring about every second summer. In the far future (2070–2099 pronounced increases with more than two 2015-like heat waves per summer are possible.

    The increasing prevalence of social networks provides researchers greater opportunities to evaluate and assess changes in public opinion and public sentiment towards issues of social consequence. Using trend and sentiment analysis is one method whereby researchers can identify changes in public perception that can be used to enhance the development of a social consciousness towards a specific public interest. The following study assessed Relative search volume (RSV) patterns for global warming (GW) and Climate change (CC) to determine public knowledge and awareness of these terms. In conjunction with this, the researchers looked at the sentiment connected to these terms in social media networks. It was found that there was a relationship between the awareness of the information and the amount of publicity generated around the terminology. Furthermore, the primary driver for the increase in awareness was an increase in publicity in either a positive or a negative light. Sentiment analysis further confirmed that the primary emotive connections to the words were derived from the original context in which the word was framed. Thus having awareness or knowledge of a topic is strongly related to its public exposure in the media, and the emotional context of this relationship is dependent on the context in which the relationship was originally established. This has value in fields like conservation, law enforcement, or other fields where the practice can and often does have two very strong emotive responses based on the context of the problems being examined.

  2. Astronomical theory of climate change

    The astronomical theory of paleo-climates aims to explain the climatic variations occurring with quasi-periodicities lying between tens and hundreds of thousands of years. The origin of these quasi-cycles lies in the astronomically driven changes in the latitudinal and seasonal distributions of the energy that the Earth receives from the Sun. These changes are then amplified by the feedback mechanisms which characterize the natural behaviour of the climate system like those involving the albedo-, the water vapor-, and the vegetation- temperature relationships. Climate models of different complexities are used to explain the chain of processes which finally link the long-term variations of three astronomical parameters to the long-term climatic variations at time scale of tens to hundreds of thousands of years. In particular, sensitivity analysis to the astronomically driven insolation changes and to the CO{sub 2} atmospheric concentrations have been performed with the 2-dimension climate model of Louvain-la-Neuve. It could be shown that this model simulates more or less correctly the entrance into glaciation around 2.75 million year (Myr) BP (before present), the late Pliocene-early Pleistocene 41-kyr (thousand years) cycle, the emergence of the 100-kyr cycle around 850 kyr BP and the glacial-interglacial cycles of the last 600 kyr. During the Late Pliocene (in an ice-free - warm world) ice sheets can only develop during times of sufficiently low summer insolation. This occurs during large eccentricity times when climatic precession and obliquity combine to obtain such low values, leading to the 41-kyr period between 3 and 1 million years BP. On the contrary in a glacial world, ice sheets persist most of the time except when insolation is very high in polar latitudes, requiring large eccentricity again, but leading this time to interglacial and finally to the 100-kyr period of the last 1 Myr. Using CO{sub 2} scenarios, it has been shown that stage 11 and stage 1

    Climate change has always occurred naturally but at a pace to which the earth has adapted well. Now, due to human activities like energy utilization and waste disposal, the earth is heating up much faster than earlier. Ecosystems, water resources, food sources, health, and human settlements are getting adversely affected. Floods and droughts are increasing, glaciers are melting, and disease is spreading. The problem is serious and it is time to act. Global consensus has been agreements; mitigation initiatives have been undertaken; hopes are up. The aim of this book is to raise the awareness of secondary school students about climate change and its impacts while enhancing their understanding of global responses. It includes a chapter specific to Indian conditions. Lucidly written and illustrated with anecdotes and visuals, this handbook will catalyse young minds into greater awareness, concern, and, hopefully, remedial action on this global threat

    There is a mounting consensus that human behavior is changing the global climate and its consequence could be catastrophic. Reducing the 24 billion metric tons of carbon dioxide emissions from stationary and mobile sources is a gigantic task involving both technological challenges and monumental financial and societal costs. The pursuit of sustainable energy resources, environment, and economy has become a complex issue of global scale that affects the daily life of every citizen of the world. The present mitigation activities range from energy conservation, carbon-neutral energy conversions, carbon advanced combustion process that produce no greenhouse gases and that enable carbon capture and sequestion, to other advanced technologies. From its causes and impacts to its solutions, the issues surrounding climate change involve multidisciplinary science and technology. This handbook will provide a single source of this information.

    Significant global climate change is inevitable. Tree species have a limited capacity to tolerate climate change or migrate through natural or artificial means. We do not know enough about the comparative resilience of forest-based, agricultural, marine or fresh water ecosystems. But it is clear that biodiverse forest ecosystems are under threat. And the threat extends beyond forests themselves. An estimated 60 million indigenous people are heavily dependent on the world's rainforests. Some 350 million people live in or close to dense forests and rely on them for subsistence or income. A further 1.2 billion people in developing countries depend on trees on farm to generate food or cash.

  8. Climatic change and security stakes

    2006-01-01

    This paper explores the relationships between climate change and security. Potential threats from climate change, as a unique source of stress or together with other factors, to human security are first examined. Some of the most explicit examples illustrate this section: food security, water availability, vulnerability to extreme events and vulnerability of small islands States and coastal zones. By questioning the basic needs of some populations or at least aggravating their precariousness, such risks to human security could also raise global security concerns, which we examine in turn, along four directions: rural exodus with an impoverishment of displaced populations, local conflicts for the use of natural resources, diplomatic tensions and international conflicts, and propagation to initially-unaffected regions through migratory flows.

  9. Teaching Climate Change Through Music

    2007-12-01

    During 2006, Peter Weiss aka "The Singing Scientist" performed many music assemblies for elementary schools (K-5) in Santa Cruz County, California, USA. These assemblies were an opportunity for him to mix a discussion of climate change with rock n' roll. In one song called "Greenhouse Glasses", Peter and his band the "Earth Rangers" wear over-sized clown glasses with "molecules" hanging off them (made with Styrofoam balls and pipe cleaners). Each molecule is the real molecular structure of a greenhouse gas, and the song explains how when the wearer of these glasses looks up in the sky, he/she can see the "greenhouse gases floating by." "I've seen more of them this year than the last / 'Cuz fossil fuels are burning fast / I wish everyone could see through these frames / Then maybe we could prevent climate change" Students sing, dance and get a visual picture of something that is invisible, yet is part of a very real problem. This performance description is used as an example of an educational style that can reach a wide audience and provide a framework for the audience as learners to assimilate future information on climate change. The hypothesis is that complex socio-environmental issues like climate change that must be taught in order to achieve sustainability are best done so through alternative mediums like music. Students develop awareness which leads to knowledge about chemistry, physics, and biology. These kinds of experiences which connect science learning to fun activities and community building are seriously lacking in primary and secondary schools and are a big reason why science illiteracy is a current social problem. Science education is also paired with community awareness (including the local plant/animal community) and cooperation. The Singing Scientist attempts to create a culture where it is cool to care about the environment. Students end up gardening in school gardens together and think about their "ecological footprint".

    Tackling climate change has often been considered the responsibility of national governments. But do individuals also have a duty to act in the face of this problem? In particular do they have a duty to adopt a greener lifestyle or to press their government to act? This review critically examines the arguments provided for and against such duties in the relevant philosophic literature. It first discusses the problem of causal inefficacy—namely the fact that individual greenhouse gas emissions...

ABSTRACT: In this research initiative, the 2013-2014 NASA NICE workshop participants will present best educational practices for incorporating climate change pedagogy. The presentation will identify strategies to enhance instruction of pre-service teachers to aligned with K-12 Science, Technology, Engineering and Mathematics (STEM) standards. The presentation of best practices should serve as a direct indicator to address pedagogical needs to include climate education within a K-12 curriculum Some of the strategies will include inquiry, direct instructions, and cooperative learning . At this particular workshop, we have learned about global climate change in regards to how this is going to impact our life. Participants have been charged to increase the scientific understanding of pre-service teachers education programs nationally to incorporate climate education lessons. These recommended practices will provide feasible instructional strategies that can be easily implemented and used to clarify possible misconceptions and ambiguities in scientific knowledge. Additionally, the presentation will promote an awareness to the many facets in which climate

    Human-influenced climate change is an observed phenomenon affecting physical and biological systems across the globe. The majority of observed impacts are related to temperature changes and are located in the northern high- and midlatitudes. However, new evidence is emerging that demonstrates that impacts are related to precipitation changes as well as temperature, and that climate change is impacting systems and sectors beyond the Northern Hemisphere. In this paper, we highlight some of this new evidence-focusing on regions and sectors that the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4) noted as under-represented-in the context of observed climate change impacts, direct and indirect drivers of change (including carbon dioxide itself), and methods of detection. We also present methods and studies attributing observed impacts to anthropogenic forcing. We argue that the expansion of methods of detection (in terms of a broader array of climate variables and data sources, inclusion of the major modes of climate variability, and incorporation of other drivers of change) is key to discerning the climate sensitivities of sectors and systems in regions where the impacts of climate change currently remain elusive. Attributing such changes to human forcing of the climate system, where possible, is important for development of effective mitigation and adaptation. Current challenges in documenting adaptation and the role of indigenous knowledge in detection and attribution are described.

    Full Text Available Climate Change has been undoubtedly the most illustrious environmental issue since late 20th century. But neither the discourse merely emerged during that time, nor it was problematized in the same way since its onset. History of Climate Change discourse reveals that from a purely scientific concern it has turned into a public agenda that is nowadays more inclined to be development problem. Transformations have brought about a complete new paradigm every time. This article presents a theoretical analysis of the Climate Change discourse and to do so it captured the underlying philosophy of the issue using Thomas Kuhn’s well-known thesis of ‘paradigm shift’. In particular it discusses about the crisis that lead the issue towards transformations; explores key perspectives around the crisis thus representation of the issue in the environmental discourse over the time. While this paper establishes that with the beginning of the 21st century, the discourse entered into a new paradigm and will reach to a critical point by the end of 2012, it finally postulates some measures that the discourse might integrate with the existing to advance beyond that point.

  20. Accounting for Climate Change: Introduction

    The assessment of greenhouse gases (GHGs) emitted to and removed from the atmosphere is high on both political and scientific agendas internationally. As increasing international concern and cooperation aim at policy-oriented solutions to the climate change problem, several issues have begun to arise regarding verification and compliance under both proposed and legislated schemes meant to reduce the human-induced global climate impact. The approaches to addressing uncertainty introduced in this article attempt to improve national inventories or to provide a basis for the standardization of inventory estimates to enable comparison of emissions and emission changes across countries. Authors of the accompanying articles use detailed uncertainty analyses to enforce the current structure of the emission trading system and attempt to internalize high levels of uncertainty by tailoring the emissions trading market rules. Assessment of uncertainty can help improve inventories and manage risk. Through recognizing the importance of, identifying and quantifying uncertainties, great strides can be made in the process of Accounting for Climate Change

    Emissions of greenhouse gases is accounted for and reported annually under the UNFCCC and the Kyoto protocol. In the current accounting system, emissions of CO2 from harvested wood products (HWP) are attributed to the year of harvest and the country of harvest. All harvested wood is thus assumed to be oxidised to CO{sub 2} in the year of harvesting, and no wood goes into long term storage. This is called the IPCC default approach. Much of the harvested wood will however be stored for a short or long period of time before it oxidises and this will cause a delayed emission of CO{sub 2}. If more wood is stored than oxidised in a given year, harvested wood products will act as a sink and a removal of CO{sub 2} is recorded. However, if the consumption of wood decreases to a level below what is oxidised, harvested wood products will act as a source and emissions of CO{sub 2} is recorded. In Norway, as on many other countries, the stock of harvested wood products has been increasing for many years, and is likely to increase further. Including emissions/removals of CO{sub 2} from harvested wood products in the post Kyoto 2012 regime is under consideration by the UNFCCC, and in that context it is imperative to evaluate estimation models and approaches for the reporting/accounting.

    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.

    2012-11-01

    Mars Recent Climate Change Workshop NASA/Ames Research Center May 15-17, 2012 Climate change on Mars has been a subject of great interest to planetary scientists since the 1970's when orbiting spacecraft first discovered fluvial landforms on its ancient surfaces and layered terrains in its polar regions. By far most of the attention has been directed toward understanding how "Early Mars" (i.e., Mars >~3.5 Gya) could have produced environmental conditions favorable for the flow of liquid water on its surface. Unfortunately, in spite of the considerable body of work performed on this subject, no clear consensus has emerged on the nature of the early Martian climate system because of the difficulty in distinguishing between competing ideas given the ambiguities in the available geological, mineralogical, and isotopic records. For several reasons, however, the situation is more tractable for "Recent Mars" (i.e., Mars during past 20 My or so). First, the geologic record is better preserved and evidence for climate change on this time scale has been building since the rejuvenation of the Mars Exploration Program in the late 1990's. The increasing coverage of the planet from orbit and the surface, coupled with accurate measurements of surface topography, increasing spatial resolution of imaging cameras, improved spectral resolution of infrared sensors, and the ability to probe the subsurface with radar, gamma rays, and neutron spectroscopy, has not only improved the characterization of previously known climate features such as polar layered terrains and glacier-related landforms, but has also revealed the existence of many new features related to recent climate change such as polygons, gullies, concentric crater fill, and a latitude dependent mantle. Second, the likely cause of climate change - spin axis/orbital variations - is more pronounced on Mars compared to Earth. Spin axis/orbital variations alter the seasonal and latitudinal distribution of sunlight, which can

    There is considerable interest in understanding the biological mechanisms that regulate carbon exchanges between the land and atmosphere, and how these exchanges respond to climate change. An understanding of soil microbial ecology is central to our ability to assess terrestrial carbon cycle-climate feedbacks, but the complexity of the soil microbial community and the many ways that it can be affected by climate and other global changes hampers our ability to draw firm conclusions on this topic. In this paper, we argue that to understand the potential negative and positive contributions of soil microbes to land-atmosphere carbon exchange and global warming requires explicit consideration of both direct and indirect impacts of climate change on microorganisms. Moreover, we argue that this requires consideration of complex interactions and feedbacks that occur between microbes, plants and their physical environment in the context of climate change, and the influence of other global changes which have the capacity to amplify climate-driven effects on soil microbes. Overall, we emphasize the urgent need for greater understanding of how soil microbial ecology contributes to land-atmosphere carbon exchange in the context of climate change, and identify some challenges for the future. In particular, we highlight the need for a multifactor experimental approach to understand how soil microbes and their activities respond to climate change and consequences for carbon cycle feedbacks.

  5. Climate engineering and the risk of rapid climate change

    2009-01-01

    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.
