    Climate change is not only a natural phenomenon, but also a global social issue. Many studies try to explore the mechanisms behind climate change and the consequences of climate change, and provide information for developing the measures to mitigate or adapt to it. For example, the IPCC reviews and assesses climate-change-related scientific information produced worldwide, thus aiming to support decision-making from a scientific perspective. However, though various international and regional c...

  3. Climate Change Conceptual Change: Scientific Information Can Transform Attitudes.

    2016-01-01

    Of this article's seven experiments, the first five demonstrate that virtually no Americans know the basic global warming mechanism. Fortunately, Experiments 2-5 found that 2-45 min of physical-chemical climate instruction durably increased such understandings. This mechanistic learning, or merely receiving seven highly germane statistical facts (Experiment 6), also increased climate-change acceptance-across the liberal-conservative spectrum. However, Experiment 7's misleading statistics decreased such acceptance (and dramatically, knowledge-confidence). These readily available attitudinal and conceptual changes through scientific information disconfirm what we term "stasis theory"-which some researchers and many laypeople varyingly maintain. Stasis theory subsumes the claim that informing people (particularly Americans) about climate science may be largely futile or even counterproductive-a view that appears historically naïve, suffers from range restrictions (e.g., near-zero mechanistic knowledge), and/or misinterprets some polarization and (noncausal) correlational data. Our studies evidenced no polarizations. Finally, we introduce HowGlobalWarmingWorks.org-a website designed to directly enhance public "climate-change cognition." PMID:26804198

    Klimaatportaal is the digital entry of Dutch ‘climate' knowledge centres, which are collaborated in the Platform Communication on Climate Change (PCCC). This collaborative venture was established in 2003 by the Dutch climate research community to improve the quality, efficiency and effectiveness of the communication of Dutch climate research. By now, eight Dutch knowledge centres are participating and still more want to join. The Ministry of Housing, Spatial Planning and the Environment (VROM) supports the PCCC and the project is implemented in collaboration with the BSIK ‘Climate Changes Spatial Planning' programme. The website provides actual and background climate change information for a wide audience on the national scale from policy makers, media to general public. By supplying integral climate information, such as observations of climate change, causes and consequences of climate system, adaptation, mitigation and energy issues, a wide spectrum of target groups will be served. The information is offered in different forms, because of the needs of different target groups. Klimaatportaal contains therefore news on climate issues, frequently asked questions and popular science reports, like the annually brochure De Staat van het Klimaat (‘The State of the Climate'). Recently, also a portal for students is added, where they can find information for their assignments. Beside the website, PCCC is organising activities as symposia and workshops and is supplying information on international issues, for example the content of the Kyoto protocol and the IPCC fourth assessment report (2007). Finally, informing the public through contacts with the media is also an important part of the PCCC. The presentation will address the strengths and weaknesses of this approach which may serve as an example for combining knowledge in outreach activities in other countries.

    Full Text Available The paper unfolds the use of urban forestry in controlling climate change and presents the use Geographical Information System (GIS as an adequate and efficient modern tool for analyzing and mapping the forest inventories for use in ameliorating the scourge of climate change in the society. The paper concludes that a holistic approach which involves the integrating urban forestry, GIS and elements of climate will go a long way to assist in saving the livelihood of mankind from being seriously affected by climate change. More so, adequate awareness should be given on the roles of urban forestry and GIS in reducing climate change. In addition, continual assessment of landuse and land cover should be done in order to detect the percentage change of urban forest resources over time with the use of GIS and remote sensing.

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

  7. Development of Climate Change Adaptation Platform using Spatial Information

    Climate change adaptation has attracted growing attention with the recent extreme weather conditions that affect people around the world. More and more countries, including the Republic of Korea, have begun to hatch adaptation plan to resolve these matters of great concern. They all, meanwhile, have mentioned that it should come first to integrate climate information in all analysed areas. That's because climate information is not independently made through one source; that is to say, the climate information is connected one another in a complicated way. That is the reason why we have to promote integrated climate change adaptation platform before setting up climate change adaptation plan. Therefore, the large-scaled project has been actively launched and worked on. To date, we researched 620 literatures and interviewed 51 government organizations. Based on the results of the researches and interviews, we obtained 2,725 impacts about vulnerability assessment information such as Monitoring and Forecasting, Health, Disaster, Agriculture, Forest, Water Management, Ecosystem, Ocean/Fisheries, Industry/Energy. Among 2,725 impacts, 995 impacts are made into a database until now. This database is made up 3 sub categories like Climate-Exposure, Sensitivity, Adaptive capacity, presented by IPCC. Based on the constructed database, vulnerability assessments were carried out in order to evaluate climate change capacity of local governments all over the country. These assessments were conducted by using web-based vulnerability assessment tool which was newly developed through this project. These results have shown that, metropolitan areas like Seoul, Pusan, Inchon, and so on have high risks more than twice than rural areas. Acknowledgements: The authors appreciate the support that this study has received from "Development of integrated model for climate change impact and vulnerability assessment and strengthening the framework for model implementation ", an initiative of the

  8. Scientific Uncertainty is Information: The Case of Climate Change (Invited)

    Gulledge, J.

    2013-12-01

    Opponents of climate policy frequently present scientific uncertainty as a reason to delay action, whereas proponents often downplay uncertainty to undermine that excuse. While it is true that we know enough to act, it is also true that there are key uncertainties that must be considered in devising effective policy. Reflecting this fact, the IPCC's Fourth Assessment Report concluded that 'Responding to climate change involves an iterative risk management process that includes both adaptation and mitigation...' Risk was devised as a framework for processing information about uncertainty into guidelines for action. The benefits of climate policy are examined in light of the characterized uncertainty around the equilibrium climate sensitivity and this information is placed into a risk-management context for climate policy. Characterized uncertainty reveals that relatively severe outcomes (righthand side of vertical dashed line) are more probably than relatively mild outcomes (left of vertical line). Moreover, the fat tail of uncertainty implies that risk can be essentially infinite.

  13. Crop advisors as climate information brokers: Building the capacity of US farmers to adapt to climate change

    Directory of Open Access Journals (Sweden)

    Maria Carmen Lemos

    2014-01-01

    Full Text Available This paper examines the role of crop advisors as brokers of climate information to support US corn farmers to adapt to climatic change. It uses quantitative data collected from a broad survey of crop advisors in the US Corn Belt to examine the factors that shape advisors’ use of (and willingness to provide climate information to their clients. Building upon a general model of climate information usability we argue that advisors’ willingness to provide climate advice to farmers is influenced by three main factors: their information seeking habits and behavior, their experience with innovation in the past, and how climate information interplays with other kinds of information that they provide—especially agronomic advice. We find that advisors’ willingness to provide climate related information depends both on factors at the individual and organizational level and on the type of advice they provide. First, at the individual and organizational levels, advisors who work in supportive organizations and who collaborate with other advisors are more likely to provide climate information. Second, advisors are more likely to provide climate information if it does not interfere with their main profit making business (e.g. provision of agronomic advice. Third, there is a significant positive relationship between trust in a greater number or sources of information and use of climate information. Fourth, the way advisors perceive short- and long-term risk also influences their willingness to provide climate information; the more concerned they are about long-term climate-related risks to farming, the more likely they are to provide (or want to provide advice based on climate information. Differently from other empirical work in the literature, our analytical model suggests that neither negative experiences with climate information in the past nor the high level of uncertainty characteristic of climate information appear to influence advisors

    Buys, Laurie; Aird, Rosemary; van Megen, Kimberley; Miller, Evonne; Sommerfeld, Jeffrey

    2014-02-01

    Disagreement within the global science community about the certainty and causes of climate change has led the general public to question what to believe and whom to trust on matters related to this issue. This paper reports on qualitative research undertaken with Australian residents from two rural areas to explore their perceptions of climate change and trust in information providers. While overall, residents tended to agree that climate change is a reality, perceptions varied in terms of its causes and how best to address it. Politicians, government, and the media were described as untrustworthy sources of information about climate change, with independent scientists being the most trusted. The vested interests of information providers appeared to be a key reason for their distrust. The findings highlight the importance of improved transparency and consultation with the public when communicating information about climate change and related policies. PMID:23825246

    Based on contributions on 120 French and foreign scientists representing different disciplines (mathematics, physics, mechanics, chemistry, biology, medicine, and so on), this report proposes an overview of the scientific knowledge and debate about climate change. It discusses the various indicators of climate evolution (temperatures, ice surfaces, sea level, biological indicators) and the various factors which may contribute to climate evolution (greenhouse gases, solar radiation). It also comments climate evolutions in the past as they can be investigated through some geological, thermal or geochemical indicators. Then, the authors describe and discuss the various climate mechanisms: solar activity, oceans, ice caps, greenhouse gases. In a third part, the authors discuss the different types of climate models which differ by the way they describe processes, and the current validation process for these models

  3. "What sceptics believe": The effects of information and deliberation on climate change scepticism.

    Hobson, Kersty; Niemeyer, Simon

    2013-05-01

    Scepticism about climate change now appears a pervasive social phenomenon. Research to date has examined the different forms that scepticism can take, from outright denial to general uncertainty. Less is known about what climate sceptics value and believe beyond their climate change doubt, as well as how "entrenched" such beliefs are. In response, this paper discusses research into public reactions to projected climate change in the Australian Capital Region. Using Q Methodology and qualitative data, it outlines five discourses of scepticism and explores the impact regional-scale climate scenarios and a deliberative forum had on these discourses. Results show that both forms of intervention stimulate "discourse migration" amongst research participants. However, migrations are rarely sustained, and sceptical positions are infrequently dispelled outright, suggesting the relationship between climate scepticism, broader beliefs, and the methods used to inform and debate about climate change, are pivotal to comprehending and addressing this issue.

    International Nuclear Information System (INIS)

    In spite of man's remarkable advances in technology, ultimately he is still dependent on the Earth's climatic system for food and fresh water. The recent occurrences in certain regions of the world of climatic extremes such as excessive rain or droughts and unseasonably high or low temperatures have led to speculation that a major climatic change is occurring on a global scale. Some point to the recent drop in temperatures in the northern hemisphere as an indication that the Earth is entering a new ice age. Others see a global warming trend that may be due to a build-up of carbon dioxide in the atmosphere. An authoritative report on the subject has been prepared by a World Meteorological Organization Panel of Experts on Climatic Change. Excerpts from the report are given. (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.

  11. Disturbing Information and Denial in the Classroom and Beyond: Climate Change, Emotions and Everyday Life

    2015-12-01

    Global warming is the most significant environmental issue of our time, yet public response in Western nations has been meager. Why have so few taken any action? Most studies of public response to climate change have focused on information deficit approaches. Many in the general public and environmental community have presumed that the public's failure to engage is a function of lack of concern about climate change. Instead, using interviews and ethnographic research on how knowledge of climate change is experienced in everyday life I describe "the social organization of climate denial" and discuss how it impacts classroom learning and the broader social understanding of climate change. Disturbing emotions of guilt, helplessness and fear of the future arose when people were confronted with the idea of climate change. People then normalized these disturbing emotions by changing the subject of conversations, shifting their attention elsewhere, telling jokes, and drawing on stock social discourses that deflected responsibility to others. The difficulty people have in making sense of climate change is in direct relation to the social world around them. This research suggests that educational strategies in the classroom and for the general public that consider and target the social, cultural and political aspects of the meaning of climate change will be most effective (in addition to factors that affect individual cognition).

    The Department of Interior Northeast Climate Science Center (NE CSC) is part of a federal network of eight Climate Science Centers created to provide scientific information and tools that managers and other parties interested in land, water, wildlife, and cultural resources can use to anticipate, monitor, and adapt to climate change. The NE CSC partners with other federal agencies, universities, and NGOs to facilitate stakeholder interaction and delivery of scientific products. For example, NE CSC researchers have partnered with the National Park Service to help managers at Acadia National Park adapt their infrastructure, operations, and ecosystems to rising seas and more extreme events. In collaboration with the tribal College of Menominee Nation and Michigan State University, the NE CSC is working with indigenous communities in Michigan and Wisconsin to co-develop knowledge of how to preserve their natural and cultural values in the face of climate change. Recently, in its largest collaborative initiative to date, the NE CSC led a cross-institutional effort to produce a comprehensive synthesis of climate change, its impacts on wildlife and their habitats, and available adaptation strategies across the entire Northeast and Midwest region; the resulting document was used by wildlife managers in 22 states to revise their Wildlife Action Plans (WAPs). Additionally, the NE CSC is working with the Wildlife Conservation Society to help inform moose conservation management. Other research efforts include hydrological modeling to inform culvert sizing under greater rainfall intensity, forest and landscape modeling to inform tree planting that mitigates the spread of invasive species, species and habitat modeling to help identify suitable locations for wildlife refugia. In addition, experimental research is being conducted to improve our understanding of how species such as brook trout are responding to climate change.

    Climate change will significantly impact the global environment, and the faster the change, the greater the risk of damage. The natural environment will be assaulted by increases in sea surface temperature and changes in the biogeochemical cycles of ocean ecosystems. Marine resource managers have begun to realize that the projected impacts of climate change in coastal and marine environments are full of uncertainties, creating enormous challenges when it comes to climate change response planning. CMIP5 GCMs produced a large amount of climate and ocean biogeochemical data for different climate change scenarios, which can provide indispensable information for marine resource planning and decision making. However, for end users, climate and ocean information needs to be processed to make it usable while applying robust scientific methods to make that processing acceptable. SimCLIM/GENIES software provides a comprehensive climate information, data management, and impact assessment platform. The software system consists of historical data and projections for atmospheric and oceanic variables, including air-temperature, precipitation, wind speed, sea surface temperature, ocean primary production, pH, pCO2, DIO, and DIC, with the potential for other data layers. These data are pre-processed using different downscaling and pattern scaling approaches, and then stored in a compact format with a very high compression ratio, which makes them more transferable. Users can carry out statistical and ensemble analyses with the software in order to better understand uncertainties. Within the software system, historical climate data, a climate change scenario generator, and impact assessment tools are all integrated into a single platform. They are policy-maker and end-user oriented and present climate information in a friendly and easily understandable manner with excellent spatial visualization tools. Moreover, the system provided and released an ArcGIS/marine add-in, which allows

    1998-03-01

    There is increasing scientific evidence to suggest that humans are gradually but certainly changing the Earth's climate. In an effort to prevent further damage to the fragile atmosphere, and with the belief that action is required now, the scientific community has been prolific in its dissemination of information on climate change. Inspired by the results of the Intergovernmental Panel on Climate Change's Second Assessment Report, Jepma and Munasinghe set out to create a concise, practical, and compelling approach to climate change issues. They deftly explain the implications of global warming, and the risks involved in attempting to mitigate climate change. They look at how and where to start action, and what organization is needed to be able to implement the changes. This book represents a much needed synopsis of climate change and its real impacts on society. It will be an essential text for climate change researchers, policy analysts, university students studying the environment, and anyone with an interest in climate change issues. A digestible version of the IPCC 1995 Economics Report - written by two of IPCC contributors with a Foreword by two of the editors of Climate Change 1995: Economics of Climate Change: i.e. has unofficial IPCC approval Focusses on policy and economics - important but of marginal interest to scientists, who are more likely to buy this summary than the full IPCC report itself Has case-studies to get the points across Separate study guide workbook will be available, mode of presentation (Web or book) not yet finalized

  20. Who trusts scientists for information about climate change? Nuclear power? Vaccines?

    US public acceptance/rejection of science on the topic of climate change has become highly polarized, with a demographic profile well established through survey research. Trust in scientists for information about climate change tends to increase with education, decrease with age, and is higher among self-identified liberals and moderates than among conservatives. Demographic profiles of people who do or do not trust scientists regarding other disputed topics are less well established. Some observers have argued that certain domains such as vaccines, nuclear power or genetically modified organisms (GMOs) could present a mirror image of climate change, with liberals instead of conservatives disproportionately rejecting science on that topic. Evidence for this mirror-image hypothesis has been mainly anecdotal, however. Here we test it systematically using statewide survey data on more than 1200 interviews, comparing five similarly worded questions that ask respondents whether they trust, don't trust, or are unsure about scientists as a source of information about ... climate change, vaccines, evolution, nuclear power safety, or GMOs. Climate change proves to be the most polarized of these topics, but all five exhibit roughly similar age, education and ideological effects -- contrary to the mirror-image hypothesis. The common patterns across five science domains, chosen for their hypothetical contrasts, map out an unexpectedly cohesive picture of who trusts scientists for information, and who does not. Implications of these survey results for public outreach and science communication are explored.

    Recurrent droughts of the last decades have led to severe impacts in forestry and agriculture in the sensitive and vulnerable low-elevation regions of Southeast Europe. Observed impacts are very likely to occur with increasing probability under projected climate conditions throughout the 21st century. In order to suggest options for adaptation and mitigation, a GIS-based Decision Support System is under development in the frame of the joint EU-national research project "Agroclimate". Impact assessments and adaptation support services are based on the simulation results of 12 regional climate models (www.ensembles-eu.org) using the A1B emission scenario until 2100. The development of the Decision Support System requires the balancing of available climatic information and required data for research and economically relevant projection needs of the end users. Here, concrete examples of the development process will be shown for the stepwise analysis and comparison of the followings: 1. Provided climate services: • projected tendencies of temperature and precipitation means and extremes until the end of the 21st century, spread of the simulation results. 2. Required information for climate impact research: • types and characteristics of climate input data, • methods and functions for deriving possible climate change impacts in forestry and agriculture (e.g. on species distribution, growth, production, yield, soil water retention, ground water table, runoff, erosion, evapotranspiration and other ecosystem services and soil properties). 3. Required climate information from the end users' side for developing adaption strategies in the affected sectors: • types of climate indicators, • possible range of the expected impacts (in magnitude and probability). 4. Gaps between climate services and the needs of impact researchers and end users (e.g. spatial and temporal scales, interpretation techniques). Experiences of supporting climate change adaptation in forestry

  3. Climate change inferred from borehole temperatures: How to improve the solution by using additional information

    Science.gov (United States)

    Bodri, L.; Čermák, V.

    Past climate changes have caused certain perturbations in the subsurface temperature field. Their inversion yields the time variations of the ground surface temperature (GST), the solution of which however may be highly non-unique. To incorporate additional information on the behaviour of the unknown function usually helps treat the non-uniqueness. The traditionally used information imposing bounding and smoothing constraints on climate history can be further significantly extended by including stochastic properties of climate. It was shown that climatic records reveal: (1) long-term persistence of climate, and (2) high intermittency of climate variations characterized by hyperbolic decrease of probability tails. We have quantified and incorporated such information into the inversion method in the form of the covariance matrix of the unknown parameters. Inversion of almost 100 temperature-depth profiles from the Czech Republic (Bodri and Čermák, 1995, 1997) provided more meaningful climatic histories in comparison with simple inversion and increased the time span that could be resolved. In present work the effectiveness of the method is illistrated on the examples of 5 selected temperature logs.

    Defining and understanding the security challenges of global climate change requires the merging of data, models, and approaches from disparate areas of the geosciences, but it also requires merging social, economic, cultural, and behavioral data and models. More importantly, to develop, get approval for, and implement responses and adaptations requires an in-depth understanding of political decision-making, decision support, and collaboration among scientists, decision makers, and stakeholders. The Johns Hopkins University Applied Physics Laboratory (APL) is creating a virtual organization, GAIA (Global Assimilation of Information for Action), to develop and demonstrate an extensible framework for identifying and acting on critical challenges in key global climate change impact areas. GAIA will establish APL as the institution for the exchange of assessments, needs, and impacts on aspects of the global climate change problem among government organizations, NGOs and scientists. This presentation will introduce the GAIA project and our primary activities in the first year.

  9. Changing climate, changing frames

    International Nuclear Information System (INIS)

    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 combination of projected climate change and land use adds uncertainty to the long-term effectiveness of current management strategies. Managers need reliable information to adjust their strategies as population density increases. However they are currently overwhelmed by the diversity of available information and the multiplicity of sources. CBI's goal is to centralize and package effectively the usable information for land managers and for the general public in order to increase awareness and promote preparation for the challenges ahead. We are designing conservation planning atlases in Data Basin for a number of landscape conservation cooperatives to address this need. We are adding some user-friendly tools to specifically serve the available climate projections and land use data in a meaningful way. By working closely with a group of managers, our goal is to understand how consideration of these projections figures into the decision-making process and refine the ways we can deliver relevant metrics. We have been holding interviews to gather information and critical feedback on existing climate-related web pages and tools, providing us with benchmarks for improvement. As it turned out, the student-manager dialogue added a component of climate change education and awareness of available tools to the project. Through an iterative process we plan to continue this exchange and address the variety of issues managers continually have to face to maintain healthy ecosystems.

  13. Using the New Scenarios Framework to Inform Climate Change Adaptation Policy in Finland

    Science.gov (United States)

    Carter, T. R.

    2013-12-01

    In 2005, Finland was among the first countries in the world to develop a national climate change adaptation strategy (Marttila et al., 2005). This included a characterization of future changes in climate and socioeconomic conditions using scenarios based on the IPCC Special Report on Emissions Scenarios (SRES - IPCC, 2000). Following a government evaluation of the strategy, completion of a national adaptation research programme, and in light of the recent European Union adaptation strategy, the Finnish strategy is now under revision. As part of this revision process, the New Scenario Framework (Moss et al., 2010) is being used to guide the mapping of future conditions in Finland out to the end of the 21st century. Future Finnish climate is being analysed using the CMIP5 climate model simulations (Taylor et al., 2012), including downscaled information based on regional climate model projections in the EURO-CORDEX project (Vautard et al., 2013). All projections are forced by the Representative Concentration Pathways (RCPs - van Vuuren et al., 2011). Socioeconomic scenarios are also being developed by outlining alternative pathways that reflect national social, economic, environmental and planning goals. These are designed according to the Shared Socioeconomic Pathway (SSP) framework of challenges to adaptation and mitigation (Kriegler et al., 2012). Work is in progress to characterize these pathways, mainly qualitatively, for different sectors in Finland. Preliminary results of the conceptual scenario development phase will be presented in this session. These initial ideas will be exchanged with representatives of ministries, regional government and key stakeholder groups. The eventual form and number of scenarios that appear in the revised strategy will be determined following a formal review of the draft document to be prepared in 2014. Future work could include quantification of scenarios, possibly mapping them onto the specific SSP worlds. This would then provide

  14. Climate change: Recent findings

    International Nuclear Information System (INIS)

    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

    According to the National Academy of Sciences in American,the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities.Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases-primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth's climate responds to them.

  17. Climate variability and climate change

    International Nuclear Information System (INIS)

    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. 19 refs.; 3 figs.; 2 tabs

    Climate Change is becoming one of the major threats to the fragile Himalayan ecosystem. It is affecting all sectors mainly fresh water, agriculture, forest, biodiversity and species. The subsistence agriculture system of Nepal is mainly rain-fed; therefore, climate change and climate extremes do have direct impacts on it. Weather extremes like droughts, floods and landslides long-lasting fog, hot and cold waves are affecting the agriculture sectors of Nepal. As human-induced climate change has already showing its impacts and it is going to be there for a long time to come, it is paramount importance to move towards the adaptation. Early warning system is an effective way for reducing the impacts of disasters. Forecasting of weather parameters (temperature, precipitation, and wind) helps farmers for their preparedness activities. With consultation with farmers and other relevant institutions, a research project was carried out, for the first time in Nepal, to identify the forecast information need to farmers and their dissemination mechanism. Community consultation workshops, key informant survey, and field observations were the techniques used for this research. Two ecological locations: Bageshwori VDC in Banke (plain) and Dhaibung VDC in Rasuwa (mountain) were taken as the pilot sites for this assessment. People in both the districts are dependent highly on agriculture and the weather extremes like hailstone, untimely rainfall; droughts are affecting their agriculture practices. They do not have confidence in the weather forecast information disseminated by the government of Nepal currently being done because it is a general forecast not done for a smaller domain and the forecast is valid only for 24 hours. The weather forecast need to the farmers in both the sites are: rainfall (intensity, duration and time), drought, and hailstone but in Banke, people wished to have the information of heat and cold waves too as they are affecting their wheat and tomato crops

  20. Climate Informed Economic Instruments to Enhance Urban Water Supply Resilience to Hydroclimatological Variability and Change

    Science.gov (United States)

    Brown, C.; Carriquiry, M.; Souza Filho, F. A.

    2006-12-01

    Hydroclimatological variability presents acute challenges to urban water supply providers. The impact is often most severe in developing nations where hydrologic and climate variability can be very high, water demand is unmet and increasing, and the financial resources to mitigate the social effects of that variability are limited. Furthermore, existing urban water systems face a reduced solution space, constrained by competing and conflicting interests, such as irrigation demand, recreation and hydropower production, and new (relative to system design) demands to satisfy environmental flow requirements. These constraints magnify the impacts of hydroclimatic variability and increase the vulnerability of urban areas to climate change. The high economic and social costs of structural responses to hydrologic variability, such as groundwater utilization and the construction or expansion of dams, create a need for innovative alternatives. Advances in hydrologic and climate forecasting, and the increasing sophistication and acceptance of incentive-based mechanisms for achieving economically efficient water allocation offer potential for improving the resilience of existing water systems to the challenge of variable supply. This presentation will explore the performance of a system of climate informed economic instruments designed to facilitate the reduction of hydroclimatologic variability-induced impacts on water-sensitive stakeholders. The system is comprised of bulk water option contracts between urban water suppliers and agricultural users and insurance indexed on reservoir inflows designed to cover the financial needs of the water supplier in situations where the option is likely to be exercised. Contract and insurance parameters are linked to forecasts and the evolution of seasonal precipitation and streamflow and designed for financial and political viability. A simulation of system performance is presented based on ongoing work in Metro Manila, Philippines. The

  3. Periglacial shallow lakes offer information about climate change. Preliminary results, King George Island

    International Nuclear Information System (INIS)

    South Shetland Islands (northern Antarctic Peninsula) represent one of the worlds areas most affected by the retreat of glaciers due to global warming. As pointed by Ingolfsson, during the last 100 years the climatic development in the western Antarctic Peninsula region has moved from a relatively cold regime to an increasingly warm regime. A large number of evidences indicate that melt water and sediment transport have increased during the past 50 years.The King George Island (KGI) ice cap, its high sensitivity to climate changes, thermal regime, ablation rates, distribution, etc. and its relation with the relative sea level, have been deeply studied and this behavior is generally extensive to the South Shetland Islands ice caps. However, there are not many recent dating studies in this area. Radiometric dating is the main way to quantify (retrospectively) the rates of various geo-hydro environmental processes of interest and further work is necessary to constrain timescales of these processes affected by recent climate changes. The few available dating studies of lacustrine sediments are restricted to lakes of sufficient size and depth, which are not widespread and have a very uneven spatial distribution. On the other hand, there are many small shallow peri glacial lagoons having a better spatial distribution, especially with respect to the fronts of receding glaciers. These lagoons are typically discarded for recent dating studies, due to a number of technical reasons. In this paper, for the first time, we present the preliminary results of a recent radiometric dating (210Pb and 137Cs) from a peri glacial shallow lagoon on Fildes Peninsula (KGI) and discuss the results in the context of the local geology and climatic conditions during the last century.The lagoon is located near the Collins Glacier retreat border and the results indicates that besides the upper sediment layers may be frozen during winter time, the stratigraphic information is still preserved and

    This paper attempts to draw a connection between information that can be gained from measurements with accelerator mass spectrometry (AMS) and the study of climate change on earth. The power of AMS to help in this endeavor is demonstrated by many contributions to these proceedings. Just like in archaeology, we are entering a phase of an 'integrated approach' to understand the various components of climate change. Even though some basic understanding emerged, we are still largely in a situation of a phenomenological description of climate change. Collecting more data is therefore of paramount interest. Based on a recent suggestion of 'geo-engineering' to take out CO{sub 2} from the atmosphere, this radical step will also be briefly discussed.

    This paper attempts to draw a connection between information that can be gained from measurements with accelerator mass spectrometry (AMS) and the study of climate change on earth. The power of AMS to help in this endeavor is demonstrated by many contributions to these proceedings. Just like in archaeology, we are entering a phase of an 'integrated approach' to understand the various components of climate change. Even though some basic understanding emerged, we are still largely in a situation of a phenomenological description of climate change. Collecting more data is therefore of paramount interest. Based on a recent suggestion of 'geo-engineering' to take out CO 2 from the atmosphere, this radical step will also be briefly discussed.

  10. Climate change matters.

    Macpherson, Cheryl Cox

    2014-04-01

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

  11. Climate change and climate policy

    International Nuclear Information System (INIS)

    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

  14. Adaptation of Australia’s Marine Ecosystems to Climate Change: Using Science to Inform Conservation Management

    2014-01-01

    Full Text Available The challenges that climate change poses for marine ecosystems are already manifesting in impacts at the species, population, and community levels in Australia, particularly in Tasmania and tropical northern Australia. Many species and habitats are already under threat as a result of human activities, and the additional pressure from climate change significantly increases the challenge for marine conservation and management. Climate change impacts are expected to magnify as sea surface temperatures, ocean chemistry, ocean circulation, sea level, rainfall, and storm patterns continue to change this century. In particular, keystone species that form the foundation of marine habitats, such as coral reefs, kelp beds, and temperate rocky reefs, are projected to pass thresholds with subsequent implications for communities and ecosystems. This review synthesises recent science in this field: the observed impacts and responses of marine ecosystems to climate change, ecological thresholds of change, and strategies for marine conservation to promote adaptation. Increasing observations of climate-related impacts on Australia’s marine ecosystems—both temperate and tropical—are making adaptive management more important than ever before. Our increased understanding of the impacts and responses of marine ecosystems to climate change provides a focus for “no-regrets” adaptations that can be implemented now and refined as knowledge improves.

    . Such a result would mean that the indicator has a negative value of information. Granted the value of information depends on the intended audience(s), with some groups being able to understand and want more technically sophisticated and detailed information presented as an indicator. However, if the goal of an indicator is to provide information to a wide range of groups, it is essential to assure that these groups have a correct understanding of the indicator, its assumptions, and the ability to use the indicator (as presented or modified) for decision-making contexts. In this talk, I will present the preliminary results of a study that is testing the value of information of a range of climate change indicators, and I will focus on indicators that use earth observations. Such results contribute to a richer understanding of the value of information of indicators, and can shape the development of both individual indicators and systems of indicators, such as the development of the indicator system for the U.S. Global Change Research Program, National Climate Assessment.

    Advancement in understanding, predicting and mitigating against climate change implies collaboration, close monitoring of Essential Climate Variable (ECV)s through development of Climate Data Record (CDR)s and effective action with specific thematic focus on human and environmental impacts. Towards this end, NCDC's Scientific Data Stewardship (SDS) Program Office developed Climate Long-term Information and Observation system (CLIO) for satellite data identification, characterization and use interrogation. This "proof-of-concept" online tool provides the ability to visualize global CDR information gaps and overlaps with options to temporally zoom-in from satellite instruments to climate products, data sets, data set versions and files. CLIO provides an intuitive one-stop web site that displays past, current and planned launches of environmental satellites in conjunction with associated imagery and detailed information. This tool is also capable of accepting and displaying Web-based input from Subject Matter Expert (SME)s providing a global to sub-regional scale perspective of all ECV's and their impacts upon climate studies. SME's can access and interact with temporal data from the past and present, or for future planning of products, datasets/dataset versions, instruments, platforms and networks. CLIO offers quantifiable prioritization of ECV/CDR impacts that effectively deal with climate change issues, their associated impacts upon climate, and this offers an intuitively objective collaboration and consensus building tool. NCDC's latest tool empowers decision makers and the scientific community to rapidly identify weaknesses and strengths in climate change monitoring strategies and significantly enhances climate change collaboration and awareness.

    In a time when sensationalism rules the online world, it is best to keep things short. The people of the online world are not passing back and forth lengthy articles, but rather brief glimpses of complex information. This is the target audience we attempt to educate. Our challenge is then to attack not only ignorance, but also apathy toward global climate change, while conforming to popular modes of learning. When communicating our scientific material, it was difficult to determine what level of information was appropriate for our audience, especially with complex subject matter. Our unconventional approach for communicating the carbon crisis as it applies to global climate change caters to these 'recreational learners'. Using story-telling devices acquired from Carolyne's biomedical art background coupled with Peter's extensive knowledge of carbon cycle and ecosystems science, we developed a dynamic series of illustrations that capture the attention of a callous audience. Adapting complex carbon cycle and climate science into comic-book-style animations creates a channel between artist, scientist, and the general public. Brief scenes of information accompanied by text provide a perfect platform for visual learners, as well as fresh portrayals of stale material for the jaded. In this way art transcends the barriers of the cerebral and the abstract, paving the road to understanding.;

    Increasing availability of ensemble outputs from general circulation models (GCMs) and regional climate models (RCMs) permits fuller examination of the implications of climate uncertainties in hydrological systems. A Bayesian statistical framework is used to combine projections by weighting and to generate probability distributions of local climate change from an ensemble of RCM outputs. A stochastic weather generator produces corresponding daily series of rainfall and potential evapotranspiration, which are input into a catchment rainfall-runoff model to estimate future water abstraction availability. The method is applied to the Thames catchment in the United Kingdom, where comparison with previous studies shows that different downscaling methods produce significantly different flow predictions and that this is partly attributable to potential evapotranspiration predictions. An extended sensitivity test exploring the effect of the weights and assumptions associated with combining climate model projections illustrates that under all plausible assumptions the ensemble implies a significant reduction in catchment water resource availability.

    Carbon Solutions New England (CSNE), a public-private partnership formed to promote collective action to achieve a low carbon society, has been working with the Governor appointed New Hampshire Climate Change Policy Task Force (NHCCTF) to support the development of a state Climate Change Action Plan. CSNE's role has been to quantify the potential carbon emissions reduction, implementation costs, and cost savings at three distinct time periods (2012, 2025, 2050) for a range of strategies identified by the Task Force. These strategies were developed for several sectors (transportation and land use, electricity generation and use, building energy use, and agriculture, forestry, and waste).New Hampshire's existing and projected economic and population growth are well above the regional average, creating additional challenges for the state to meet regional emission reduction targets. However, by pursuing an ambitious suite of renewable energy and energy efficiency strategies, New Hampshire may be able to continue growing while reducing emissions at a rate close to 3% per year up to 2025. This suite includes efficiency improvements in new and existing buildings, a renewable portfolio standard for electricity generation, avoiding forested land conversion, fuel economy gains in new vehicles, and a reduction in vehicle miles traveled. Most (over 80%) of these emission reduction strategies are projected to provide net economic savings in 2025.A collaborative and iterative process was developed among the key partners in the project. The foundation for the project's success included: a diverse analysis team with leadership that was committed to the project, an open source analysis approach, weekly meetings and frequent communication among the partners, interim reporting of analysis, and an established and trusting relationship among the partners, in part due to collaboration on previous projects.To develop decision-relevant information for the Task Force, CSNE addressed

    In recent years, public perception of the scientific consensus on human-caused global warming has been disturbingly low, in contrast to the overwhelming level of agreement among climate scientists and in peer-reviewed research. The misperception is partly cultural, with a significant link between perceived consensus and political ideology, and partly informational with all cultural groups exhibiting the misperception to varying degrees. This universal 'consensus gap' is in large part due to a persistent and focused misinformation campaign casting doubt on the consensus, dating back as early as the 1980s. Opponents of climate action have long recognized that perception of scientific consensus is linked to support for climate policy, a link only acknowledged by social scientists in the last few years. How do we counter the all-too-effective misinformation campaign? Psychological research tells us that a crucial aspect of effective refutations is an alternative narrative. In this case, an important counter-narrative to the consensus story is the strategy to perpetuate the impression of ongoing scientific debate. I will also present recent research into the effect that consensus information has on climate beliefs of Australians and Americans. For both groups, the consensus message significantly increased beliefs about human-caused global warming and outperformed interventions that feature evidence or scientists' expertise. For the Australian sample, consensus information partially neutralised the biasing influence of ideology. However, for Americans, a backfire effect (reduced climate belief) was observed for a small minority holding strong conservative views. A psychological model employing Bayesian Networks indicates that a key element to the backfire effect is conspiratorial thinking, consistent with other research finding a link between rejection of climate science and conspiratorial ideation. Thus when presented to a general audience, consensus information has an

    It is becoming increasingly clear, at least on a theoretical level, that modelers of the potential impacts of climate change must impose that change upon the world as it will be configured sometime in the future rather than confine their attention to considerations of what would happen to the world as it looks now. Initial baselines which focus on current circumstances are certainly worthwhile points of departure in any study, of course, but the truth is that social, economic, and political systems will evolve as the future unfolds; and careful analysis of that evolution across a globe experiencing changes in its climate must be undertaken, as well. In the vernacular of the analysts' workroom, while it may be interesting to try to see what would happen to dumb farmers'' who continue to do things as they always have regardless of what happens, it is critically important to evaluate the need for any sort of policy response to climate change in a world of smart farmers'' who will have observed the ramifications of climate change and responded in their own best interest. 9 refs., 2 figs.

  11. Global vs climate change

    International Nuclear Information System (INIS)

    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

    Energy Technology Data Exchange (ETDEWEB)

    Jones, R. [CSIRO Atmospheric Research, PMB1 Aspendale, Victoria 3195 (Australia)

    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

  17. The economic value of drought information for water management under climate change: a case study in the Ebro basin

    Directory of Open Access Journals (Sweden)

    S. Quiroga

    2011-03-01

    Full Text Available Drought events in the Mediterranean are likely to increase in frequency, duration and intensity due to climate change, thereby affecting crop production. Information about drought is valuable for river basin authorities and the farmers affected by their decisions. The economic value of this information and the resulting decisions are of interest to these two stakeholder groups and to the information providers. Understanding the dynamics of extreme events, including droughts, in future climate scenarios for the Mediterranean is being improved continuously. This paper analyses the economic value of information on drought events taking into account the risk aversion of water managers. We consider the effects of drought management plans on rice production in the Ebro river basin. This enables us to compute the willingness to compensate the river basin authority for more accurate information allowing for better decision-making. If runoff is reduced, river basin planners can consider the reduction of water allocation for irrigation in order to eliminate the risk of water scarcity. Alternately, river basin planners may decide to maintain water allocation and accept a reduction of water supply reliability, leaving farmers exposed to drought events. These two alternatives offer different risk levels for crop production and farmers' incomes which determine the value of this information to the river basin authority. The information is relevant for the revision of River Basin Management Plans of the Water Framework Directive (WFD within the context of climate change.

    International Nuclear Information System (INIS)

    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.

    Due to their conic shape and the reduction of area with increasing elevation, mountain ecosystems were early identified as potentially very sensitive to global warming. Moreover, mountain systems may experience unprecedented rates of warming during the next century, two or three times higher than that records of the 20th century. In this context, species distribution models (SDM) have become important tools for rapid assessment of the impact of accelerated land use and climate change on the distribution plant species. In this study, we developed and tested new predictor variables for species distribution models (SDM), specific to current and future geographic projections of plant species in a mountain system, using the Western Swiss Alps as model region. Since meso- and micro-topography are relevant to explain geographic patterns of plant species in mountain environments, we assessed the effect of scale on predictor variables and geographic projections of SDM. We also developed a methodological framework of space-for-time evaluation to test the robustness of SDM when projected in a future changing climate. Finally, we used a cellular automaton to run dynamic simulations of plant migration under climate change in a mountain landscape, including realistic distance of seed dispersal. Results of future projections for the 21st century were also discussed in perspective of vegetation changes monitored during the 20th century. Overall, we showed in this study that, based on the most severe A1 climate change scenario and realistic dispersal simulations of plant dispersal, species extinctions in the Western Swiss Alps could affect nearly one third (28.5%) of the 284 species modeled by 2100. With the less severe B1 scenario, only 4.6% of species are predicted to become extinct. However, even with B1, 54% (153 species) may still loose more than 80% of their initial surface. Results of monitoring of past vegetation changes suggested that plant species can react quickly to the

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

To the contrary, this paper builds on the assumption that economic agents may suffer for a while from limited knowledge about the average and variability of physical impa...

    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)

    Current climate and future climate-warming runs with the RegCM Regional Climate Model (RCM) at 50 and 11 km-resolutions forced by the ECHAM GCM are used to examine whether the increased resolution of the RCM introduces novel information in the precipitation field when the models are run for the mountainous region of the Hellenic peninsula. The model results are inter-compared with the resolution of the RCM output degraded to match that of the GCM, and it is found that in both the present and future climate runs the regional models produce more precipitation than the forcing GCM. At the same time, the RCM runs produce increases in precipitation with climate warming even though they are forced with a GCM that shows no precipitation change in the region. The additional precipitation is mostly concentrated over the mountain ranges, where orographic precipitation formation is expected to be a dominant mechanism. It is found that, when examined at the same resolution, the elevation heights of the GCM are lower than those of the averaged RCM in the areas of the main mountain ranges. It is also found that the majority of the difference in precipitation between the RCM and the GCM can be explained by their difference in topographic height. The study results indicate that, in complex topography regions, GCM predictions of precipitation change with climate warming may be dry biased due to the GCM smoothing of the regional topography.

  6. Scenarios of climate change

    International Nuclear Information System (INIS)

    This article provides an overview of current and prospected climate changes, their causes and implied threats, and of a possible route to keep the changes within a tolerable level. The global mean temperature has up to 2005 risen by almost 0.8 C deg., and the change expected by 2100 is as large as glacial-interglacial changes in the past, which were commonly spread out over 10 000 years. As is well known, the principle actor is man-made CO2, which, together with other anthropogenic gases, enhances the atmosphere's greenhouse effect. The only man-made cooling agent appears to be atmospheric aerosols. Atmospheric CO2 has now reached levels unprecedented during the past several million years. Principal threats are a greatly reduced biodiversity (species extinction), changes in the atmospheric precipitation pattern, more frequent weather extremes, and not the least, sea level rise. The expected precipitation pattern will enhance water scarcity in and around regions that suffer from water shortage already, affecting many countries. Sea level rise will act on a longer time scale. It is expected to amount to more than 50 cm by 2100, and over the coming centuries the potential rise is of the order of 10 m. A global-mean temperature increase of 2 C deg. is often quoted as a safe limit, beyond which irreversible effects must be expected. To achieve that limit, a major, rapid, and coordinated international effort will be needed. Up to the year 2050, the man-made CO2 releases must be reduced by at least 50%. This must be accompanied by a complete overhaul of the global energy supply toward depending increasingly on the Sun's supply of energy, both directly and in converted form, such as wind energy. Much of the information and insight available today has been generated by the Intergovernmental Panel on Climate Change (IPCC), in particular its Fourth Assessment Report of 2007, which greatly advanced both public attention and political action.

  10. Comparative Risk Assessment to Inform Adaptation Priorities for the Natural Environment: Observations from the First UK Climate Change Risk Assessment

    Directory of Open Access Journals (Sweden)

    2015-11-01

    Full Text Available Risk assessment can potentially provide an objective framework to synthesise and prioritise climate change risks to inform adaptation policy. However, there are significant challenges in the application of comparative risk assessment procedures to climate change, particularly for the natural environment. These challenges are evaluated with particular reference to the first statutory Climate Change Risk Assessment (CCRA and evidence review procedures used to guide policy for the UK government. More progress was achieved on risk identification, screening and prioritisation compared to risk quantification. This was due to the inherent complexity and interdependence of ecological risks and their interaction with socio-economic drivers as well as a climate change. Robust strategies to manage risk were identified as those that coordinate organisational resources to enhance ecosystem resilience, and to accommodate inevitable change, rather than to meet specific species or habitats targets. The assessment also highlighted subjective and contextual components of risk appraisal including ethical issues regarding the level of human intervention in the natural environment and the proposed outcomes of any intervention. This suggests that goals for risk assessment need to be more clearly explicated and assumptions on tolerable risk declared as a primer for further dialogue on expectations for managed outcomes. Ecosystem-based adaptation may mean that traditional habitats and species conservation goals and existing regulatory frameworks no longer provide the best guide for long-term risk management thereby challenging the viability of some existing practices.

  11. Assessing fit, interplay, and scale: Aligning governance and information for improved water management in a changing climate

    Water managers have long experienced the challenges of managing water resources in a variable climate. However, climate change has the potential to reshape the experiential landscape by, for example, increasing the intensity and duration of droughts, shifting precipitation timing and amounts, and changing sea levels. Given the uncertainty in evaluating potential climate risks as well as future water availability and water demands, scholars suggest water managers employ more flexible and adaptive science-based management to manage uncertainty (NRC 2009). While such an approach is appropriate, for adaptive science-based management to be effective both governance and information must be concordant across three measures: fit, interplay and scale (Young 2002)(Note 1). Our research relies on interviews of state water managers and related experts (n=50) and documentary analysis in five U.S. states to understand the drivers and constraints to improving water resource planning and decision-making in a changing climate using an assessment of fit, interplay and scale as an evaluative framework. We apply this framework to assess and compare how water managers plan and respond to current or anticipated water resource challenges within each state. We hypothesize that better alignment between the data and management framework and the water resource problem improves water managers' facility to understand (via available, relevant, timely information) and respond appropriately (through institutional response mechanisms). In addition, better alignment between governance mechanisms (between the scope of the problem and identified appropriate responses) improves water management. Moreover, because many of the management challenges analyzed in this study concern present day issues with scarcity brought on by a combination of growth and drought, better alignment of fit, interplay, and scale today will enable and prepare water managers to be more successful in adapting to climate change

    Global climate appears to be changing at an unprecedented rate. Climate change can be caused by several factors that include variations in solar radiation received by earth, oceanic processes (such as oceanic circulation), plate tectonics, and volcanic eruptions, as well as human-induced alterations of the natural world. Many human activities, such as the use of fossil fuel and the consequent accumulation of greenhouse gases in the atmosphere, land consumption, deforestation, industrial processes, as well as some agriculture practices are contributing to global climate change. Indeed, many authors have reported on the current trend towards global warming (average surface temperature has augmented by 0.6 °C over the past 100 years), decreased precipitation, atmospheric humidity changes, and global rise in extreme climatic events. The magnitude and cause of these changes and their impact on human activity have become important matters of debate worldwide, representing climate change as one of the greatest challenges of the modern age. Although many articles have been written based on observations and various predictive models of how climate change could affect social, economic and health systems, only few studies exist about the effects of this change on skin physiology and diseases. However, the skin is the most exposed organ to environment; therefore, cutaneous diseases are inclined to have a high sensitivity to climate. For example, global warming, deforestation and changes in precipitation have been linked to variations in the geographical distribution of vectors of some infectious diseases (leishmaniasis, lyme disease, etc) by changing their spread, whereas warm and humid environment can also encourage the colonization of the skin by bacteria and fungi. The present review focuses on the wide and complex relationship between climate change and dermatology, showing the numerous factors that are contributing to modify the incidence and the clinical pattern of many

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

    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.

    A problem of making education relevant to the workplace tasks is a key problem of higher education in the professional field of environmental sciences. To answer this challenge several new courses for students of "Climatology" and "Meteorology" specialties were developed and implemented at the Tomsk State University, which comprises theoretical knowledge from up-to-date environmental sciences with computational tasks. To organize the educational process we use an open-source course management system Moodle (www.moodle.org). It gave us an opportunity to combine text and multimedia in a theoretical part of educational courses. The hands-on approach is realized through development of innovative trainings which are performed within the information-computational web GIS platform "Climate" (http://climate.scert.ru/). The platform has a set of tools and data bases allowing a researcher to perform climate changes analysis on the selected territory. The tools are also used for students' trainings, which contain practical tasks on climate modeling and climate changes assessment and analysis. Laboratory exercises are covering three topics: "Analysis of regional climate changes"; "Analysis of climate extreme indices on the regional scale"; and "Analysis of future climate". They designed to consolidate students' knowledge of discipline, to instill in them the skills to work independently with large amounts of geophysical data using modern processing and analysis tools of web-GIS platform "Climate" and to train them to present results obtained on laboratory work as reports with the statement of the problem, the results of calculations and logically justified conclusion. Thus, students are engaged in n the use of modern tools of the geophysical data analysis and it cultivates dynamic of their professional learning. The approach can help us to fill in this gap because it is the only approach that offers experience, increases students involvement, advance the use of modern

    Population and Climate Change provides the first systematic in-depth treatment of links between two major themes of the 21st century: population growth (and associated demographic trends such as aging) and climate change. It is written by a multidisciplinary team of authors from the International Institute for Applied Systems Analysis who integrate both natural science and social science perspectives in a way that is comprehensible to members of both communities. The book will be of primary interest to researchers in the fields of climate change, demography, and economics. It will also be useful to policy-makers and NGOs dealing with issues of population dynamics and climate change, and to teachers and students in courses such as environmental studies, demography, climatology, economics, earth systems science, and international relations.

    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...

    According to the United Nations Framework Convention on Climate Change (UNFCCC), climate change is attributed directly or indirectly to human activities that alter the composition of the global atmosphere. It is a phenomenon that is still inadequately understood by the general public. Planners, policy makers and even within institutions of learning, but one which is bound to affect our environment and development activities. There is therefore need for information dissemination, systematic research, policy formulation, and development of strategies for managing climate change. The book is divided into five parts, Part I presents basic information on climate change; Part II looks at climatic change and natural resources; Part III discusses implications of climate change; Part IV presents ethical issues related to climatic change; and Part V deals with responses to climate change

    International Nuclear Information System (INIS)

    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

    2011-12-01

    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

    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

    This document updates Natsource's previous briefing on the October 24 Climate change draft plan' outlining significant changes and modifications incorporated in the November 21, 2002 version of the Climate change plan for Canada' as tabled in the House of Commons by the Minister of the Environment. The changes in the new version of the Plan are the result of continued consultations with industry and the provinces. The revised Plan addresses nine of the 12 concerns expressed by the provinces. Key changes include: (1) establishment of sectoral emissions reduction targets through negotiated covenants with a regulatory or financial backstop; (2) guaranteeing a limit of 55 Megatonnes reductions for covered sectors under the covenants and trading system; (3) introducing flexibility in timing by signaling willingness on the part of the Government to discuss acceptance of commitments over a longer term; (4) promising to work with industry on options for providing protection against risks associated with sustained carbon prices above certain levels; (5) designing implementation system in such a way as to not disadvantage those companies that have taken early action in emission reductions; (6) building in contingencies, assessing progress and adjusting the Federal approach and level of investment; (7) remaining engaged in joint efforts with the United States to minimize impacts on Canadian competitiveness. The Federal Government also recognizes the need for further research in addressing climate model uncertainties, in providing regional-scale climate change information, in future evolution of the climate in the Arctic, and in determining the record of past climate variability and extremes

    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.

    Current Climate Variability & Change is the ninth among a suite of ten interconnected, sequential labs that address all 39 climate-literacy concepts in the U.S. Global Change Research Program's Climate Literacy: The Essential Principles of Climate Sciences. The labs are as follows: Solar Radiation & Seasons, Stratospheric Ozone, The Troposphere, The Carbon Cycle, Global Surface Temperature, Glacial-Interglacial Cycles, Temperature Changes over the Past Millennium, Climates & Ecosystems, Current Climate Variability & Change, and Future Climate Change. All are inquiry-based, on-line products designed in a way that enables students to construct their own knowledge of a topic. Questions representative of various levels of Webb's depth of knowledge are embedded in each lab. In addition to the embedded questions, each lab has three or four essential questions related to the driving questions for the lab suite. These essential questions are presented as statements at the beginning of the material to represent the lab objectives, and then are asked at the end as questions to function as a summative assessment. For example, the Current Climate Variability & Change is built around these essential questions: (1) What has happened to the global temperature at the Earth's surface, in the middle troposphere, and in the lower stratosphere over the past several decades?; (2) What is the most likely cause of the changes in global temperature over the past several decades and what evidence is there that this is the cause?; and (3) What have been some of the clearly defined effects of the change in global temperature on the atmosphere and other spheres of the Earth system? An introductory Prezi allows the instructor to assess students' prior knowledge in relation to these questions, while also providing 'hooks' to pique their interest related to the topic. The lab begins by presenting examples of and key differences between climate variability (e.g., Mt. Pinatubo eruption) and

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

  20. Through a mirror, darkly-using climate change information for land management

    Slater, T.F. [Bureau of Land Management, Salt Lake City, UT (United States)

    1995-09-01

    The writer Bruce Hutchison uses the phrase: {open_quotes}The land, always the land!{close_quotes} The land is a common denominator linking the ages. But the {open_quotes}land{close_quotes} in the broadest sense is a vast collection of natural components, events, and interconnections. It is complex, only partially understood, and ever-changing. Our ultimate challenge at this time is to SEE, as we look into the mirror of time. Regardless of the shadows of uncertainty, we must peer hopefully into the mirror to make meaningful connections between the past, the present, and the future. This is not easy. Traditional resource planning has been based on the short-term focus of today and tomorrow. That focus is beginning to change through a concept now popularized as {open_quotes}ecosystem management.{close_quotes} BLM recently has begun applying this concept in the formulation of the Eastern Utah Ecosystem Planning Initiative that is intended to give expanded dimensions to the planning and management of public land resources. These dimensions will give more attention to spatial (regional) and temporal (long-term) expectations. This paper investigates the theoretical and practical problems in linking the past to the future, using as the example the new planning initiative for Eastern Utah. It provides insights which may be applied to land-use planning and management, through new perspectives regarding changing climate and ecosystem patterns.

  2. Managing Identifiers for Elements of Provenance of the Third National Climate Assessment in the Global Change Information System (Invited)

    Science.gov (United States)

    Tilmes, C.; Aulenbach, S.; Duggan, B.; Goldstein, J.

    2013-12-01

    A Federal Advisory Committee (The "National Climate Assessment and Development Advisory Committee" or NCADAC) has overseen the development of a draft climate report that after extensive review will be considered by the Federal Government in the Third National Climate Assessment (NCA). This comprehensive report (1) Integrates, evaluates, and interprets the findings of the Program and discusses the scientific uncertainties associated with such findings; (2) Analyzes the effects of global change on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems, and biological diversity; and (3) Analyzes current trends in global change, both human-induced and natural, and projects major trends for the subsequent 25 to 100 years. The U.S. Global Change Program (USGCRP), composed of the 13 federal agencies most concerned with global change, is building a Global Change Information System (GCIS) that will ultimately organize access to all of the research, data, and information about global change from across the system. A prototype of the system has been constructed that captures and presents all of the elements of provenance of the NCA through a coherent data model and friendly front end web site. This work will focus on the globally unique and persistent identifiers used to reference and organize those items. These include externally referenced items, such as DOIs used by scientific journal publishers for research articles or by agencies as dataset identifiers, as well as our own internal approach to identifiers, our overall data model and experiences managing persistent identifiers within the GCIS.

  3. Classifying climate change adaptation frameworks

    Science.gov (United States)

    2014-05-01

    Complex socio-ecological demographics are factors that must be considered when addressing adaptation to the potential effects of climate change. As such, a suite of deployable climate change adaptation frameworks is necessary. Multiple frameworks that are required to communicate the risks of climate change and facilitate adaptation. Three principal adaptation frameworks have emerged from the literature; Scenario - Led (SL), Vulnerability - Led (VL) and Decision - Centric (DC). This study aims to identify to what extent these adaptation frameworks; either, planned or deployed are used in a neighbourhood vulnerable to climate change. This work presents a criterion that may be used as a tool for identifying the hallmarks of adaptation frameworks and thus enabling categorisation of projects. The study focussed on the coastal zone surrounding the Sizewell nuclear power plant in Suffolk in the UK. An online survey was conducted identifying climate change adaptation projects operating in the study area. This inventory was analysed to identify the hallmarks of each adaptation project; Levels of dependency on climate model information, Metrics/units of analysis utilised, Level of demographic knowledge, Level of stakeholder engagement, Adaptation implementation strategies and Scale of adaptation implementation. The study found that climate change adaptation projects could be categorised, based on the hallmarks identified, in accordance with the published literature. As such, the criterion may be used to establish the matrix of adaptation frameworks present in a given area. A comprehensive summary of the nature of adaptation frameworks in operation in a locality provides a platform for further comparative analysis. Such analysis, enabled by the criterion, may aid the selection of appropriate frameworks enhancing the efficacy of climate change adaptation.

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

  7. Ireland and climate change

    International Nuclear Information System (INIS)

    As the rise of sea level, the higher frequency of tempests, and the threat of water shortages in some parts of the country are the major stakes for Ireland in the struggle against climate change, this report gives an overview of greenhouse gas emissions in this country (globally and per sector) and of their evolution. It presents the Irish policy to struggle against climate change since 2000, its public actors (ministries, agencies), its different action plans (National Climate Change Strategy, energy sector planning, promotion of renewable energies, transport sector planning), and sector-based and tax measures implemented in Ireland. It discusses the limitations of the current policy (insufficient results, limited domestic measures, socioeconomic obstacles, complex political steering), describes the new European context and the present Irish context (economic crisis). Some new orientations are discussed

    One of the main priorities of the WWF is to increase the implementing of solutions relative to the greenhouse effect fight. In this framework the foundation published a study on the nuclear facing the climatic change problem. The following chapters are detailed: the nuclear and the negotiations on the climatic change; the nuclear close; the unrealistic hypothesis of the nuclear forecast; the nuclear facing other energy supplying options; supplying efficiency for heating, electric power, gas and renewable energies; the consumption efficiency facing the nuclear; the economical aspects; the deregulation effect; the political aspects; the nuclear AND the greenhouse effect.

  11. Climatic change. What solutions?

    International Nuclear Information System (INIS)

    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.

  12. Climate change and amphibians

    Directory of Open Access Journals (Sweden)

    Corn, P. S.

    2005-01-01

    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.

  16. Climate change velocity underestimates climate change exposure in mountainous regions

    Science.gov (United States)

    Dobrowski, Solomon Z.; Parks, Sean A.

    2016-08-01

    Climate change velocity is a vector depiction of the rate of climate displacement used for assessing climate change impacts. Interpreting velocity requires an assumption that climate trajectory length is proportional to climate change exposure; longer paths suggest greater exposure. However, distance is an imperfect measure of exposure because it does not quantify the extent to which trajectories traverse areas of dissimilar climate. Here we calculate velocity and minimum cumulative exposure (MCE) in degrees Celsius along climate trajectories for North America. We find that velocity is weakly related to MCE; each metric identifies contrasting areas of vulnerability to climate change. Notably, velocity underestimates exposure in mountainous regions where climate trajectories traverse dissimilar climates, resulting in high MCE. In contrast, in flat regions velocity is high where MCE is low, as these areas have negligible climatic resistance to movement. Our results suggest that mountainous regions are more climatically isolated than previously reported.

    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.

    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.

    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.

    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.

  4. Integrated assessment of climate change

    International Nuclear Information System (INIS)

    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

    For almost two decades both national polls and in-depth studies of global warming perceptions have shown that people commonly conflate weather and global climate change. Not only are current weather events such as anecdotal heat waves, droughts or cold spells treated as evidence for or against global warming, but weather changes such as warmer weather and increased storm intensity and frequency are the consequences most likely to come to mind. Distinguishing weather from climate remains a challenge for many. This weather 'framing' of global warming may inhibit behavioral and policy change in several ways. Weather is understood as natural, on an immense scale that makes controlling it difficult to conceive. Further, these attributes contribute to perceptions that global warming, like weather, is uncontrollable. This talk presents an analysis of data from public opinion polls, focus groups, and cognitive studies regarding people's mental models of and 'frames' for global warming and climate change, and the role weather plays in these. This research suggests that priming people with a model of global warming as being caused by a "thickening blanket of carbon dioxide" that "traps heat" in the atmosphere solves some of these communications problems and makes it more likely that people will support policies to address global warming.

  6. A Second Chance: What can informal science learning institutions uniquely contribute to public inquiry about climate change? (Invited)

    Bartels, D.

    2009-12-01

    The science of climate change is complicated. Even for adult audiences, scientific ideas such as non-linear modeling, probability and uncertainty, complexity and multivariate relationships, and the dynamic relationship between physical and human systems were not part of the typical curriculum for most of us in school. Moreover, many adults are invested in the myth that the aim of scientists is “truth-seeking” as opposed to finding the best interpretation that fits the best available empirical data. Science too often is presented even to adults as sets of answers and certainties. The forthcoming “Green Book” from the NSF Advisory Committee on Environmental Research and Education makes a novel recommendation that in these times adult environmental science literacy is as critical as education programs for K-12 and university students. Its reasoning is the stakes regarding the most pressing global environmental issues of our day—climate change chief among them—likely require such significant change in human behavior in the immediate term that it cannot wait for another generation of children to grow up. Practices and behaviors must change immediately. The report identifies the approximately 15,000 informal science learning institutions across the United States as the perfect adult science education delivery system to address this challenge. However, for the informal science learning community to engage this challenge most effectively, it must take care in its response given the complexity of the science, even for adults. It cannot perpetuate the idea of science as static and certain or separate itself from the social sciences. Yet the scientific community has very important stories to tell which have an immediate urgency to humankind. How do you explain the importance of uncertainty and science as a process while at the same time conveying confidence about scientific consensus where it exists? We will discuss ways of framing these important questions about

    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 ( CO2, CH4, N2O, HFCs, PFCs and SF6) amounted to 79.2 million tonnes of CO2 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 CO2.

    This book, which was published in time for the Earth Summit in Brazil in June 1992, is likely to make a huge impact on the political and economic agendas of international policy makers. It summarizes the scientific findings of Working Group I of the IPCC in the first part of the book. While acknowledging the uncertainties in subsequent chapters, it challenges and expands upon the existing views on how we should tackle the problems of climate change.

  9. Climate change and forest

    International Nuclear Information System (INIS)

    Studies of the earth's present forms of vegetation show that the climate change to be expected from double the current greenhouse gas concentrations would have a fundamental impact on forest structures. This problem can be confronted in two ways: Either by adusting long-term silvicultural planning according to predictions derived from vegetation model calculations; or by managing forests in the manner of a flexible response strategy until changes actually occur. An evaluation of representative surveys of forests in Bavaria has shown that contrary to widerspread regions of Bavaria. This suggests that in the event of a warning by 1 to 2 C, assuming all other climate parameters to remain roughly constant, the beech could play a major role in the forest structure in large parts of Bavaria. The data material also shows that in defiance of all pessimistic forecasts the growth of beech has markedly improved over the past decade. To date the only explanations offered for this phenomenon are growth-stimulating changes in the chemical composition of the atmosphere, specifically the rise in carbon dioxide; and the enhanced nitrogen deposition in the soil. This example shows that the immense number of unpredictable influences prohibit long-term forecasts on forest development. Now if the forest is made up of a large number of tree species whose most favoured climatic ranges are known, then it is possible to meet climate changes with early silvicultural interventions and so preclude forest destruction. Scientifically founded silviculature can thus become an important support for the stability of our forests. (orig.)

  11. Stop the climate change

    International Nuclear Information System (INIS)

    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).

  12. Climate Change and Forests

    International Nuclear Information System (INIS)

    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

  16. Climate change in Australia: technical report 2007

    International Nuclear Information System (INIS)

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

  19. Agriculture and climate change

    International Nuclear Information System (INIS)

    How will increases in levels of CO2 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 CO2 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 CO2 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 CO2 by growth and utilization of biomass. Large areas are already available that could be devoted to energy crops

    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 change is altering the wildlands of the west, principally through changes in the water cycle. In many places there is and will be less water than there once was, and such water as there is will runoff from mountain snowpacks earlier each year. A drier climate in the western U.S. will promote a greater role of fire and other mortality events for many forests. Consequently, how managers prepare for and respond to events such as fire, or large scale insect outbreaks is becoming more important as the climate changes. Sometimes, these events punctuate gradual changes to ecosystems, and sometimes they generate stepwise changes in ecosystems, making it clear that climate vulnerability assessments should account for disturbance in their calculus. We describe a framework of how fire and climate change work together to affect forest and fish communities. Learning how to adapt will come from testing, probing, and pushing that framework to discover the most robust strategies to increased disturbance risks. The western U.S. defies generalizations, and much learning must necessarily be local in implication. We argue that successful adaptation does not simply constitute setting forest and stream communities on the appropriate path, rather it requires teaching wildland resource managers how to learn quickly and respond insightfully as the events associated climate change unfold.

  3. Integrated risk analysis of global climate change

    International Nuclear Information System (INIS)

    This paper discusses several factors that should be considered in integrated risk analyses of global climate change. We begin by describing how the problem of global climate change can be subdivided into largely independent parts that can be linked together in an analytically tractable fashion. Uncertainty plays a central role in integrated risk analyses of global climate change. Accordingly, we consider various aspects of uncertainty as they relate to the climate change problem. We also consider the impacts of these uncertainties on various risk management issues, such as sequential decision strategies, value of information, and problems of interregional and intergenerational equity.

    This paper has been developed to show how the future of the climate of our planet could become. The factors that takes places in this possible change are also carefully explained. The human action over the environment is probably disturbing the atmospheric system. The processes that involves this perturbations are shown: pollution, fires in hugh regions such as Amazonia Central Australia, Central and East Africa and some others. Factors like these seems are destroying the ozone shell. We also explain the problems to be sure that the expectatives for the future are reliable. Finally, we propose some solutions for this situation. Special situations like nuclear winter or the desertization are also included. (Author)

  6. Modelling coral reef futures to inform management: can reducing local-scale stressors conserve reefs under climate change?

    Directory of Open Access Journals (Sweden)

    Georgina G Gurney

    Full Text Available Climate change has emerged as a principal threat to coral reefs, and is expected to exacerbate coral reef degradation caused by more localised stressors. Management of local stressors is widely advocated to bolster coral reef resilience, but the extent to which management of local stressors might affect future trajectories of reef state remains unclear. This is in part because of limited understanding of the cumulative impact of multiple stressors. Models are ideal tools to aid understanding of future reef state under alternative management and climatic scenarios, but to date few have been sufficiently developed to be useful as decision support tools for local management of coral reefs subject to multiple stressors. We used a simulation model of coral reefs to investigate the extent to which the management of local stressors (namely poor water quality and fishing might influence future reef state under varying climatic scenarios relating to coral bleaching. We parameterised the model for Bolinao, the Philippines, and explored how simulation modelling can be used to provide decision support for local management. We found that management of water quality, and to a lesser extent fishing, can have a significant impact on future reef state, including coral recovery following bleaching-induced mortality. The stressors we examined interacted antagonistically to affect reef state, highlighting the importance of considering the combined impact of multiple stressors rather than considering them individually. Further, by providing explicit guidance for management of Bolinao's reef system, such as which course of management action will most likely to be effective over what time scales and at which sites, we demonstrated the utility of simulation models for supporting management. Aside from providing explicit guidance for management of Bolinao's reef system, our study offers insights which could inform reef management more broadly, as well as general

  9. Financing for climate change

    International Nuclear Information System (INIS)

    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.

    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. The book will be divided into the following sections: Scientific Evidence of Cl...

  11. Climate change and the potential global distribution of Aedes aegypti: spatial modelling using geographical information system and CLIMEX

    Directory of Open Access Journals (Sweden)

    Hassan M. Khormi

    2014-05-01

    Full Text Available We examined the potential added risk posed by global climate change on the dengue vector Aedes aegypti abundance using CLIMEX, a powerful tool for exploring the relationship between the fundamental and realised niche of any species. After calibrating the model using data from several knowledge domains, including geographical distribution records, we estimated potential distributions of the mosquito under current and future potential scenarios. The impact of climate change on its potential distribution was assessed with two global climate models, the CSIRO-Mk3.0 and the MIROC-H, run with two potential, future emission scenarios (A1B and A2 published by the Intergovernmental Panel on Climate Change. We compared today’s climate situation with two arbitrarily chosen future time points (2030 and 2070 to see the impact on the worldwide distribution of A. aegypti. The model for the current global climate indicated favourable areas for the mosquito within its known distribution in tropical and subtropical areas. However, even if much of the tropics and subtropics will continue to be suitable, the climatically favourable areas for A. aegypti globally are projected to contract under the future scenarios produced by these models, while currently unfavourable areas, such as inland Australia, the Arabian Peninsula, southern Iran and some parts of North America may become climatically favourable for this mosquito species. The climate models for the Aedes dengue vector presented here should be useful for management purposes as they can be adapted for decision/making regarding allocation of resources for dengue risk toward areas where risk infection remains and away from areas where climatic suitability is likely to decrease in the future.

    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.

    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.

  19. Climate changes and biodiversity

    International Nuclear Information System (INIS)

    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

  20. Integrating Climate Change Scenarios and Co-developed Policy Scenarios to Inform Coastal Adaptation: Results from a Tillamook County, Oregon Knowledge to Action Network

    2014-12-01

    Local decision-makers often lack both the information and tools to reduce their community's overall vulnerability to current and future climate change impacts. Managers are restricted in their actions by the scale of the problem, inherent scientific uncertainty, limits of information exchange, and the global nature of available data, rendering place-based strategies difficult to generate. Several U.S. Pacific Northwest coastal communities are already experiencing chronic erosion and flooding, hazards only to be exacerbated by sea level rise and changing patterns of storminess associated with climate change. To address these issues, a knowledge to action network (KTAN) consisting of local Tillamook County stakeholders and Oregon State University researchers, was formed to project future flooding and erosion impacts and determine possible adaptation policies to reduce vulnerability. Via an iterative scenario planning process, the KTAN has developed four distinct adaptation policy scenarios, including 'Status Quo', 'Hold The Line', 'ReAlign', and 'Laissez-Faire'. These policy scenarios are being integrated with a range of climate change scenarios within the modeling framework Envision, a multi-agent GIS-based tool, which allows for the combination of physical processes data, probabilistic climate change information, coastal flood and erosion models, and stakeholder driven adaptation strategies into distinct plausible future scenarios. Because exact physical and social responses to climate change are impossible to ascertain, information about the differences between possible future scenarios can provide valuable information to decision-makers and the community at large. For example, the fewest projected coastal flood and erosion impacts to buildings occur under the 'ReAlign' policy scenario (i.e., adaptation strategies that move dwellings away from the coast) under both low and high climate change scenarios, especially in comparison to the 'Status Quo' or 'Hold The

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

  4. Competitiveness and climate change

    International Nuclear Information System (INIS)

    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)

  5. Indications of climatic change

    International Nuclear Information System (INIS)

    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.)

  6. Geopolitics of climate change

    International Nuclear Information System (INIS)

    Climate change has become an international policy topic. Its stakes go beyond the simple ecological question to encompass the overall global equilibrium, and in particular the North-South relations. This book, with solid references and illustrated with a tenth of color maps, examines the geopolitical dimension of global warming. Who are the countries responsible or considered to be so? Who are those who will be the most impacted? What population migrations have already started or have to be foreseen? What are the international security risks? The author presents also the different international cooperation mechanisms already implemented and takes stock of the present day situation of negotiations. We are entering into the critical phase, and probably into the potentially dramatic phase as well. This book allows to understand its key aspects and driving forces

    The focus of the great majority of climate change impact studies is on changes in mean climate. In terms of climate model output, these changes are more robust than changes in climate variability. By concentrating on changes in climate means, the full impacts of climate change on biological and human systems are probably being seriously underestimated. Here, we briefly review the possible impacts of changes in climate variability and the frequency of extreme events on biological and food syst...

  10. Climate change policy position

    International Nuclear Information System (INIS)

    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

  11. Applied climate-change analysis: the climate wizard tool.

    Directory of Open Access Journals (Sweden)

    Evan H Girvetz

    Full Text Available BACKGROUND: Although the message of "global climate change" is catalyzing international action, it is local and regional changes that directly affect people and ecosystems and are of immediate concern to scientists, managers, and policy makers. A major barrier preventing informed climate-change adaptation planning is the difficulty accessing, analyzing, and interpreting climate-change information. To address this problem, we developed a powerful, yet easy to use, web-based tool called Climate Wizard (http://ClimateWizard.org that provides non-climate specialists with simple analyses and innovative graphical depictions for conveying how climate has and is projected to change within specific geographic areas throughout the world. METHODOLOGY/PRINCIPAL FINDINGS: To demonstrate the Climate Wizard, we explored historic trends and future departures (anomalies in temperature and precipitation globally, and within specific latitudinal zones and countries. We found the greatest temperature increases during 1951-2002 occurred in northern hemisphere countries (especially during January-April, but the latitude of greatest temperature change varied throughout the year, sinusoidally ranging from approximately 50 degrees N during February-March to 10 degrees N during August-September. Precipitation decreases occurred most commonly in countries between 0-20 degrees N, and increases mostly occurred outside of this latitudinal region. Similarly, a quantile ensemble analysis based on projections from 16 General Circulation Models (GCMs for 2070-2099 identified the median projected change within countries, which showed both latitudinal and regional patterns in projected temperature and precipitation change. CONCLUSIONS/SIGNIFICANCE: The results of these analyses are consistent with those reported by the Intergovernmental Panel on Climate Change, but at the same time, they provide examples of how Climate Wizard can be used to explore regionally- and temporally

    In the face of climate change induced economic uncertainty, households may employ migration as an adaptation strategy to diversify their livelihood portfolio through remittances. However, it is unclear whether such climate migration will be documented or undocumented. In this study we combine detailed migration histories with daily temperature and precipitation information for 214 weather stations to investigate whether climate change more strongly impacts undocumented or documented migration from 68 rural Mexican municipalities to the U.S. during the years 1986–1999. We employ two measures of climate change, the warm spell duration index (WSDI) and the precipitation during extremely wet days (R99PTOT). Results from multi-level event-history models demonstrate that climate-related international migration from rural Mexico was predominantly undocumented. We conclude that programs to facilitate climate change adaptation in rural Mexico may be more effective in reducing undocumented border crossings than increased border fortification.

  15. Preparing for climate change.

    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

  16. 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�...

  17. Teaching Climate Change Through Music

    Weiss, P. S.

    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".

    A growing body of research illuminates the role that changes in climate have had on violent conflict and social instability in the recent past. Across a diversity of contexts, high temperatures and irregular rainfall have been causally linked to a range of conflict outcomes. These findings can be paired with climate model output to generate projections of the impact future climate change may have on conflicts such as crime and civil war. However, there are large degrees of uncertainty in such projections, arising from (i) the statistical uncertainty involved in regression analysis, (ii) divergent climate model predictions, and (iii) the unknown ability of human societies to adapt to future climate change. In this article, we review the empirical evidence of the climate-conflict relationship, provide insight into the likely extent and feasibility of adaptation to climate change as it pertains to human conflict, and discuss new methods that can be used to provide projections that capture these three sources of uncertainty.

    Between 1950 and 2030, the share of the world's population that lives in cities is predicted to grow from 30% to 60%. This urbanization has consequences for the likelihood of climate change and for the social costs that climate change will impose on the world's quality of life. This paper examines how urbanization affects greenhouse gas production, and it studies how urbanites in the developed and developing world will adapt to the challenges posed by climate change.

  3. Changes in drought risk with climate change

    International Nuclear Information System (INIS)

    As human activity adds more greenhouse gases to the atmosphere, most climate change scenarios predict rising temperatures and decreased rainfall in the east of New Zealand. This means eastern parts of the country are expected to experience more droughts as the 21st century goes on. Our report seeks for the first time to define the possible range of changes in future drought risk. This report was commissioned because of the importance of drought for agriculture and water resources. The report aims to give central and local government and the agriculture sector an indication of how big future drought changes could be in the various regions. This information can be relevant in managing long-term water resources and land use, including planning for irrigation schemes.

  4. Climate change science - beyond IPCC

    International Nuclear Information System (INIS)

    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

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

    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.

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

    International Nuclear Information System (INIS)

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

    In its 2013-2014 Fifth Assessment Report (AR5), the Intergovernmental Panel on Climate Change (IPCC) states that there is a greater than 95 percent chance that rising global average temperatures, observed since the mid-20th century, are primarily due to human activities. As had been predicted in the 1800s, the principal driver of climate change over the past century has been increasing levels of atmospheric greenhouse gases associated with fossil-fuel combustion, changing land-use practices, and other human activities. Atmospheric concentrations of the greenhouse gas carbon dioxide are now approximately 40 percent higher than in preindustrial times. Concentrations of other important greenhouse gases, including methane and nitrous oxide, have increased rapidly as well.

    2003-07-01

    The impacts of weather and climate extremes (floods, storms, drought, etc) have historically set back development and will continue to do so into the future, especially in developing countries. It is essential to understand how future climate change will be manifest as weather and climate extremes in order to implement policies of sustainable development. The purpose of this article is to demonstrate that natural processes have caused the climate to change and it is unlikely that human influences will dominate the natural processes. Any suggestion that implementation of the Kyoto Protocol will avoid future infrastructure damage, environmental degradation and loss of life from weather and climate extremes is a grand delusion.

  13. The social construct of climate and climate change

    International Nuclear Information System (INIS)

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

    International Nuclear Information System (INIS)

    The Government of the Philippines signed the UN Framework Convention on Climate change on June 12, 1992 and the Philippine Congress ratified it in 1994. The Philippine Government has also subsequently created the Inter-Agency Committee on Climate Change (IACCC). The GOP is currently preparing the Philippine Country Study to address climate change. The first phase of the work was financed by a grant from the US Country Studies Program which is led by the US Department of Energy. The Study includes the following elements: a) development of a National Inventory of GHG emission and Sinks; b) vulnerability assessment and evaluation of adaptations of coastal resources; c) identification of alternative programs and measures to promote mitigation and/or adaptation to climate change; d) public information and education campaign; and e) development of the National Action Plan on Climate Change.

    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.

When making climate sensitive decisions, policy makers and adaptation planners would benefit from information on local scales and for user-specific quantiles (e.g. the hottest/coldest 5% of days) and thresholds (e.g. days above 28 ° C), not just mean changes. Here, we translate observations of weather into observations of climate change, providing maps of the changing shape of climatic temperature distributions across Europe since 1950. The provision of such information from observations is valuable to support decisions designed to be robust in today’s climate, while also providing data against which climate forecasting methods can be judged and interpreted. The general statement that the hottest summer days are warming faster than the coolest is made decision relevant by exposing how the regions of greatest warming are quantile and threshold dependent. In a band from Northern France to Denmark, where the response is greatest, the hottest days in the temperature distribution have seen changes of at least 2 ° C, over four times the global mean change over the same period. In winter the coldest nights are warming fastest, particularly in Scandinavia. (letter)

  18. Schneider lecture: From climate change impacts to climate change risks

    Field, C. B.

    Steve Schneider was a strong proponent of considering the entire range of possible climate-change outcomes. He wrote and spoke frequently about the importance of low probability/high consequence outcomes as well as most likely outcomes. He worked tirelessly on communicating the risks from overlapping stressors. Technical and conceptual issues have made it difficult for Steve's vision to reach maturity in mainstream climate-change research, but the picture is changing rapidly. The concept of climate-change risk, considering both probability and consequence, is central to the recently completed IPCC Fifth Assessment Report, and the concept frames much of the discussion about future research agendas. Framing climate change as a challenge in managing risks is important for five core reasons. First, conceptualizing the issue as being about probabilities builds a bridge between current climate variability and future climate change. Second, a formulation based on risks highlights the fact that climate impacts occur primarily in extremes. For historical variability and future impacts, the real concern is the conditions under which things break and systems fail, namely, in the extremes. Third, framing the challenge as one of managing risks puts a strong emphasis on exploring the full range of possible outcomes, including low-probability, high/consequence outcomes. Fourth, explaining climate change as a problem in managing risks links climate change to a wide range of sophisticated risk management tools and strategies that underpin much of modern society. Fifth, the concept of climate change as a challenge in managing risks helps cement the understanding that climate change is a threat multiplier, adding new dimensions and complexity to existing and emerging problems. Framing climate change as a challenge in managing risks creates an important but difficult agenda for research. The emphasis needs to shift from most likely outcomes to most risky outcomes, considering the full

  19. How climate changes

    International Nuclear Information System (INIS)

    Climate variability on time scales of years through centuries seems to be dominated by two kinds of recurring fluctuations, each exhibiting characteristic evolution in time. One is the El Nino/Southern oscillation phenomenon, a tropical ocean/atmosphere autofluctuation that is phase locked to the annual cycle and recurs at 3 or 4 year intervals. The other fluctuation exhibits a recurrence period of about 1 1/3 century and appears to be forced from high latitudes in winter, more strongly from the Arctic than from the Antarctic. This paper is an overview of the morphology and teleconnections associated with this longer period fluctuation. The dynamic forcing is exhibited most strongly as deepening (or shallowing) of the sub-polar surface pressure trough in both the Atlantic and Pacific sectors and some changes in the central pressure of the subtropical highs. This can be visualized as strengthening (or weakening) of the mean winter fields of pressure and wind, reflected by southward displacement and strengthening of the major wind and SST fields over the Atlantic and Pacific. These dynamical relationships are reflected in teleconnections extending from the Arctic far into the southern hemisphere. The range of variability of surface wind strength is 20-30%, (a factor of 2 in wind stress on the ocean) with wind strongest in the 1860s, sudden weakening in the northern hemisphere in the 1870s, continued weakening to a minimum in 1930s, strengthening since then, especially since the 1960s

    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.

    Understanding the costs that climate change will exact on society is crucial to devising an appropriate policy response. One of the channels through while climate change will affect human society is through vector-borne diseases whose epidemiology is conditioned by ambient ecology. This paper introduces the literature on malaria, its cost on society, and the consequences of climate change to the physics community in hopes of inspiring synergistic research in the area of climate change and health. It then demonstrates the use of one ecological indicator of malaria suitability to provide an order-of-magnitude assessment of how climate change might affect the malaria burden. The average of Global Circulation Model end-of-century predictions implies a 47% average increase in the basic reproduction number of the disease in today's malarious areas, significantly complicating malaria elimination efforts.

    Climate change impacts on vertebrates have consequences for marine ecosystem structures and services. We review marine fish, mammal, turtle, and seabird responses to climate change and discuss their potential for adaptation. Direct and indirect responses are demonstrated from every ocean. Because of variation in research foci, observed responses differ among taxonomic groups (redistributions for fish, phenology for seabirds). Mechanisms of change are (i) direct physiological responses and (ii) climate-mediated predator-prey interactions. Regional-scale variation in climate-demographic functions makes range-wide population dynamics challenging to predict. The nexus of metabolism relative to ecosystem productivity and food webs appears key to predicting future effects on marine vertebrates. Integration of climate, oceanographic, ecosystem, and population models that incorporate evolutionary processes is needed to prioritize the climate-related conservation needs for these species.

  15. Climate change and nuclear power

    International Nuclear Information System (INIS)

    The nuclear industry has increased its efforts to have nuclear power plants integrated into the post- Kyoto negotiating process of the UN Framework Convention on Climate Change. The Nuclear Energy Institute (NEI) states: ''For many reasons, current and future nuclear energy projects are a superior method of generating emission credits that must be considered as the US expands the use of market- based mechanisms designed around emission credit creation and trading to achieve environmental goals ''. The NEI considers that nuclear energy should be allowed to enter all stages of the Kyoto ''flexibility Mechanisms'': emissions trading, joint implementation and the Clean Development Mechanism. The industry sees the operation of nuclear reactors as emission ''avoidance actions'' and believes that increasing the generation of nuclear power above the 1990 baseline year either through extension and renewal of operating licenses or new nuclear plant should be accepted under the flexibility mechanisms in the same way as wind, solar and hydro power. For the time being, there is no clear definition of the framework conditions for operating the flexibility mechanisms. However, eligible mechanisms must contribute to the ultimate objective of the Climate Convention of preventing ''dangerous anthropogenic interference with the climate system''. The information presented in the following sections of this report underlines that nuclear power is not a sustainable source of energy, for many reasons. In conclusion, an efficient greenhouse gas abatement strategy will be based on energy efficiency and not on the use of nuclear power. (author)

    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

    An integrated multi-disciplinary team of researchers from the University of Arizona and the International Research Institute for Climate and Society at Columbia University have joined forces with communities and institutions in the Caribbean, South Asia and West Africa to develop relevant, usable climate information and connect it to real decisions and development challenges. The overall objective of the "Integrating Climate Information and Decision Processes for Regional Climate Resilience" program is to build community resilience to negative impacts of climate variability and change. We produce and provide science-based climate tools and information to vulnerable peoples and the public, private, and civil society organizations that serve them. We face significant institutional challenges because of the geographical and cultural distance between the locale of climate tool-makers and the locale of climate tool-users and because of the complicated, often-inefficient networks that link them. To use an accepted metaphor, there is great institutional difficulty in coordinating the supply of and the demand for useful climate products that can be put to the task of building local resilience and reducing climate vulnerability. Our program is designed to reduce the information constraint and to initiate a linkage that is more demand driven, and which provides a set of priorities for further climate tool generation. A demand-driven approach to the co-production of appropriate and relevant climate tools seeks to meet the direct needs of vulnerable peoples as these needs have been canvassed empirically and as the benefits of application have been adequately evaluated. We first investigate how climate variability and climate change affect the livelihoods of vulnerable peoples. In so doing we assess the complex institutional web within which these peoples live -- the public agencies that serve them, their forms of access to necessary information, the structural constraints

  1. Climate change and the Great Barrier Reef

    International Nuclear Information System (INIS)

    Full text: Full text: Climate change is now recognised as the greatest long-term threat to the Great Barrier Reef (GBR). Managers face a future in which the impacts of climate change on tropical marine ecosystems are becoming increasingly frequent and severe. Further degradation is inevitable as the climate continues to change but the extent of the decline will depend on the rate and magnitude of climate change and the resilience of the ecosystem. Changes to the ecosystem have implications for the industries and regional communities that depend on the GBR. Climate projections for the GBR region include increasing air and sea temperatures, ocean acidification, nutrient enrichment (via changes in rainfall), altered light levels, more extreme weather events, changes to ocean circulation and sea level rise. Impacts have already been observed, with severe coral bleaching events in 1998 and 2002, and mass mortalities of seabirds linked to anomalously warm summer conditions. Climate change also poses significant threats to the industries and communities that depend on the GBR ecosystem, both directly and indirectly through loss of natural resources; industries such as recreational and commercial fishing, and tourism, which contributes to a regional tourism industry worth $6.1 billion (Access Economics 2005). A vulnerability assessment undertaken by leading experts in climate and marine science identified climate sensitivities for GBR species, habitats, key processes, GBR industries and communities (Johnson and Marshall 2007). This information has been used to develop a Climate Change Action Plan for the GBR. The Action Plan is a five-year program aimed at facilitating targeted science, building a resilient ecosystem, assisting adaptation of industries and communities, and reducing climate footprints. The Action Plan identifies strategies to review current management arrangements and raise awareness of the issue in order to work towards a resilient ecosystem. Integral to

  3. Climate change and insurance: a critical appraisal

    International Nuclear Information System (INIS)

    Several issues relating to insurance and the damage costs of climate change are discussed. It is argued that the option of insuring climate change is severely limited because the associated damages are hardly quantifiable and little diversifiable; in addition, binding contracts are a problem on long time scales and in an international context. Hedging, consumption smoothing over time, precautionary investments and liability are not to be presented under the heading of insurance, not only because this unnecessarily and confusingly expands the traditional definition of insurance, but also because this could create a false sense of security. The impact of climate change on the profitability of the commercial insurance sector is not likely to be severe, as the insurance companies are capable of shifting changed risks to the insured, provided that they are properly and timely informed on the consequences of climate change.

    Since the mid-1980s, long-lead climate forecasts have been developed and used to predict the onset of El Nino events and their impact on climate variability. This report discusses user responses to seasonal climate forecasts in southern Africa, with an emphasis on small-scale farmers in Namibia and Tanzania. The study examines how farmers received and used the forecasts in the agricultural season of 1997/1998. It also summarises a workshop on user responses to seasonal forecasts in southern Africa. Comparison of case studies across south Africa revealed differences in forecast dissemination strategies and in the capacity to respond to extreme events. However, improving these strategies and the capacity to respond to the forecasts would yield net profit to agriculture in southern Africa. In anticipation of potential changes in the frequency or magnitude of extreme events associated with global climate change, there clearly is a need for improved seasonal forecasts and improved information dissemination.

  10. Information report presented by the Commission of European Affairs about the international negotiations relative to climate change - No. 2391

    International Nuclear Information System (INIS)

    The conclusion put forward by scientists is clear-cut and alarming: the current efforts to limit the increase in global temperature to 2 deg. C are insufficient. This was the aim which the international community set itself in order to avoid the catastrophic effect of climate change. In their fifth report, the experts of the IPCC recommend the limitation, before the end of the century, of the concentration of greenhouse gases in the atmosphere, to 450 parts per million. This level is equivalent, according to the scientists, to a rise in global temperature of 2 deg. C and would imply a reduction of between 40 % and 70 % of global emissions between now and 2050 and would envisage decreasing them to an 'almost zero level' before the end of the century. The last Conference of the United Nations on Climate Change which was held in Warsaw at the end of 2013 (COP19) was a 'stepping-stone' conference according to the very words of its participants. In order to remain on track concerning the global agreement on climate for 2015, two types of decision were taken there: - the notion of bringing nations together in the framework of a global initiative aiming to reduce emissions quite quickly so as to allow humanity to avoid, in the long term, the dangerous threshold concerning climate change, whilst, at the same time, strengthening the capabilities for adaptation; - the idea of moving so as to speed up and bolster the current plan of action. The Warsaw Conference managed to chart the way towards the Paris Conference on Climate in 2015 during which a new world agreement on climate should be signed. However, it also showed that the road will be long and difficult. Basic questions remain unanswered and require a high level of political commitment. The negotiations on climate change of the 20. Climate Change Conference or COP, will take place in Lima between December 1 - 12, 2014. The Conference will thus be the last within the United Nations Framework Convention on Climate Change

    This guidebook presents a selection of technologies for climate change adaptation in the agriculture sector. A set of 22 adaptation technologies are showcased. These are based primarily on the principles of agroecology, but also include scientific technologies of climate and biological sciences complemented by important sociological and institutional capacity building processes that are required for climate change to function. The technologies cover: 1) Planning for climate change and variability. 2) Sustainable water use and management. 3) Soil management. 4) Sustainable crop management. 5) Sustainable livestock management. 6) Sustainable farming systems. 7) Capacity building and stakeholder organisation. Technologies that tend to homogenise the natural environment and agricultural production have low possibilities of success in environmental stress conditions that are likely to result from climate change. On the other hand, technologies that allow for, and promote diversity are more likely to provide a strategy which strengthens agricultural production in the face of uncertain future climate change scenarios. The 22 technologies showcased in this guidebook have been selected because they facilitate the conservation and restoration of diversity while also providing opportunities for increasing agricultural productivity. Many of these technologies are not new to agricultural production practices, but they are implemented based on the assessment of current and possible future impacts of climate change in a particular location. agroecology is an approach that encompasses concepts of sustainable production and biodiversity promotion and therefore provides a useful framework for identifying and selecting appropriate adaptation technologies for the agriculture sector. The guidebook provides a systematic analysis of the most relevant information available on climate change adaptation technologies in the agriculture sector. It has been compiled based on a literature

  12. Arctic adaptation and climate change

    International Nuclear Information System (INIS)

    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 CO2; 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

  13. Challenges of climate change. Which climate governance?

    International Nuclear Information System (INIS)

    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

    2014-12-01

    Climate information and services for Impacts, Adaptation and Vulnerability (IAV) Assessments are of great concern. In order to develop probabilistic regional climate information that represents the uncertainty in climate scenario experiments in Japan, we compared the physics ensemble experiments using the 60km global atmospheric model of the Meteorological Research Institute (MRI-AGCM) with multi-model ensemble experiments with global atmospheric-ocean coupled models (CMIP3) of SRES A1b scenario experiments. The MRI-AGCM shows relatively good skills particularly in tropics for temperature and geopotential height. Variability in surface air temperature of physical ensemble experiments with MRI-AGCM was within the range of one standard deviation of the CMIP3 model in the Asia region. On the other hand, the variability of precipitation was relatively well represented compared with the variation of the CMIP3 models. Models which show the similar reproducibility in the present climate shows different future climate change. We couldn't find clear relationships between present climate and future climate change in temperature and precipitation. We develop a new method to produce probabilistic information of climate change scenarios by weighting model ensemble experiments based on a regression model (Krishnamurti et al., Science, 1999). The method can be easily applicable to other regions and other physical quantities, and also to downscale to finer-scale dependent on availability of observation dataset. The prototype of probabilistic information in Japan represents the quantified structural uncertainties of multi-model ensemble experiments of climate change scenarios.

  17. Extreme precipitation events in a changing climate

    International Nuclear Information System (INIS)

    Canada's natural environment and built infrastructure are affected significantly by extreme weather events, with repercussions such as economic losses. The purpose of this presentation was to research whether these losses are due to greater societal vulnerability or climatic extremes or both, and to determine whether engineering design codes and standards need to be changed to ensure that infrastructure, such as dams, can withstand future climatic extremes. Environment Canada maintains long term climate and water observing networks and uses climate data in the development of building codes and engineering design standards and practices. Because of the variable nature of precipitation, the range of spatial scales, climate system influences and the importance of local topography on precipitation occurrence and amount, analyzing historical trends and making future projections for precipitation, particularly extremes, are challenging. This presentation discussed historical climate trends and future projections with reference to changes temperature, precipitation and precipitation extremes. In addition, extreme weather events and recent trends were discussed together with human influence on trends and projections. The presentation demonstrated how the climate in Canada has varied during the period of instrumental records. Future predictions for precipitation extremes were developed using climate models and statistical downscaling. The presentation also highlighted atmospheric hazards information under development for emergency preparedness and disaster management planning. It was concluded that future climate changes are inevitable and will likely affect the frequency of heavy precipitation events. 14 refs., 1 tab., 19 figs

  18. Can Climate Change Negotiations Succeed?

    Directory of Open Access Journals (Sweden)

    Jon Hovi

    2013-09-01

    Full Text Available More than two decades of climate change negotiations have produced a series of global climate agreements, such as the Kyoto Protocol and the Copenhagen Accords, but have nevertheless made very limited progress in curbing global emissions of greenhouse gases. This paper considers whether negotiations can succeed in reaching an agreement that effectively addresses the climate change problem. To be effective, a climate agreement must cause substantial emissions reductions either directly (in the agreement's own lifetime or indirectly (by paving the way for a future agreement that causes substantial emissions reductions directly. To reduce global emissions substantially, an agreement must satisfy three conditions. Firstly, participation must be both comprehensive and stable. Secondly, participating countries must accept deep commitments. Finally, the agreement must obtain high compliance rates. We argue that three types of enforcement will be crucial to fulfilling these three conditions: (1 incentives for countries to ratify with deep commitments, (2 incentives for countries that have ratified with deep commitments to abstain from withdrawal, and (3 incentives for countries having ratified with deep commitments to comply with them. Based on assessing the constraints that characterize the climate change negotiations, we contend that adopting such three-fold potent enforcement will likely be politically infeasible, not only within the United Nations Framework Convention on Climate Change, but also in the framework of a more gradual approach. Therefore, one should not expect climate change negotiations to succeed in producing an effective future agreement—either directly or indirectly.

    The Atmospheric Radiation Measurement Climate Research Facility (ACRF) develops public outreach materials and educational resources for schools. Studies prove that science education in rural and indigenous communities improves when educators integrate regional knowledge of climate and environmental issues into school curriculum and public outreach materials. In order to promote understanding of ACRF climate change studies, ACRF Education and Outreach has developed interactive kiosks about climate change for host communities close to the research sites. A kiosk for the North Slope of Alaska (NSA) community was installed at the Iupiat Heritage Center in 2003, and a kiosk for the Tropical Western Pacific locales will be installed in 2005. The kiosks feature interviews with local community elders, regional agency officials, and Atmospheric Radiation Measurement (ARM) Program scientists, which highlight both research and local observations of some aspects of environmental and climatic change in the Arctic and Pacific. The kiosks offer viewers a unique opportunity to learn about the environmental concerns and knowledge of respected community elders, and to also understand state-of-the-art climate research. An archive of interviews from the communities will also be distributed with supplemental lessons and activities to encourage teachers and students to compare and contrast climate change studies and oral history observations from two distinct locations. The U.S. Department of Energy's ACRF supports education and outreach efforts for communities and schools located near its sites. ACRF Education and Outreach has developed interactive kiosks at the request of the communities to provide an opportunity for the public to learn about climate change from both scientific and indigenous perspectives. Kiosks include interviews with ARM scientists and provide users with basic information about climate change studies as well as interviews with elders and community leaders

  20. Japan's Ambivalent Diplomacy on Climate Change

    International Nuclear Information System (INIS)

    Japan often pictures itself as an environmental leader. While many examples of Japan's actions against climate change are in line with global climate change norms, others can be in opposition to them. This study, based on first hand interviews with Japanese policy makers and actors from the private and civil society sector, gives an informed perspective on the process through which Japan came to integrate and implement, at the domestic level, the international objective of climate change prevention, pointing out the discrepancies, tensions or synergies that emerged. As the current governance on climate change, and particularly after the Copenhagen conference, tends to reassert the importance of the national level against the global one, the Japanese case can serve as an example of tools and strategies that fully integrate the domestic level

  6. The science of climate change

    International Nuclear Information System (INIS)

    Today, it can no longer be doubted that the greenhouse effect is being intensified ('enhanced') by human activity. The remaining uncertainties concern the magnitude, timing and regional distribution of the consequent climate change. The costs of control will almost certainly be elevated if action is delayed and the precautionary principle is not adopted. And today the size and extent of the global population precludes migration as an acceptable way of avoiding the impacts of climate change. Yet, so far only the Netherlands has published its greenhouse gas (GHG) emission inventory and reduction strategy in accordance with the 1992 UN Framework Convention on Climate Change (FCCC) (''Climate change convention'', Safe Energy 92). A Bill containing legislation to ratify FCCC is currently being prepared by the Swedish government. Britain and other European Community and Organisation for Economic Cooperation and Development (OECD) nations plan to ratify the FCCC by 1994. (author)

    Climate change may cause more climate variability and further results in more frequent extreme hydrological events which may greatly influence reservoir¡¦s abilities to provide service, such as water supply and flood mitigation, and even danger reservoir¡¦s safety. Some local studies have identified that climate change may cause more flood in wet period and less flow in dry period in Taiwan. To mitigate climate change impacts, more reservoir space, i.e. less storage, may be required to store higher flood in wet periods, while more reservoir storage may be required to supply water for dry periods. The goals to strengthen adaptive capacity of water supply and flood mitigation are conflict under climate change. This study will focus on evaluating the impacts of climate change on reservoir systems. The evaluation procedure includes hydrological models, a reservoir water balance model, and a water supply system dynamics model. The hydrological models are used to simulate reservoir inflows under different climate conditions. Future climate scenarios are derived from several GCMs. Then, the reservoir water balance model is developed to calculate reservoir¡¦s storage and outflows according to the simulated inflows and operational rules. The ability of flood mitigation is also evaluated. At last, those outflows are further input to the system dynamics model to assess whether the goal of water supply can still be met. To mitigate climate change impacts, the implementing adaptation strategies will be suggested with the principles of risk management. Besides, uncertainties of this study will also be analyzed. The Feitsui reservoir system in northern Taiwan is chosen as a case study.

  14. Climate Change and Agricultural Vulnerability

    International Nuclear Information System (INIS)

    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

    2009-04-01

    Regional Climate Change Index (RCCI), is developed based on regional mean precipitation change, mean surface air temperature change, and change in precipitation and temperature interannual variability. The RCCI is a comparative index designed to identify the most responsive regions to climate change, or Hot- Spots. The RCCI is calculated for Seven land regions over North Africa and Arabian region from the latest set of climate change projections by 14 global climates for the A1B, A2 and B1 IPCC emission scenarios. The concept of climate change can be approaches from the viewpoint of vulnerability or from that of climate response. In the former case a Hot-Spot can be defined as a region for which potential climate change impacts on the environment or different activity sectors can be particularly pronounced. In the other case, a Hot-Spot can be defined as a region whose climate is especially responsive to global change. In particular, the characterization of climate change response-based Hot-Spot can provide key information to identify and investigate climate change Hot-Spots based on results from multi-model ensemble of climate change simulations performed by modeling groups from around the world as contributions to the Fourth Assessment Report of Intergovernmental Panel on Climate Change (IPCC). A Regional Climate Change Index (RCCI) is defined based on four variables: change in regional mean surface air temperature relative to the global average temperature change ( or Regional Warming Amplification Factor, RWAF ), change in mean regional precipitation (P % , of present day value ), change in regional surface air temperature interannual variability (T % ,of present day value), change in regional precipitation interannual variability (P % ,of present day value ). In the definition of the RCCI it is important to include quantities other than mean change because often mean changes are not the only important factors for specific impacts. We thus also include inter

  2. Fair adaptation to climate change

    International Nuclear Information System (INIS)

    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 CO2 concentrations in the atmosphere and a carbon tax of $20-50 per carbon equivalent ton could provide the initial instruments for operationalising the principles.

    The first hit in an internet search for "global warming" using any of the three leading search engines (Google, Bing, or Yahoo) is the article "Global warming" in the online encyclopedia Wikipedia. The article garners about half a million page views per month. In addition to the site's visibility with the public, Wikipedia's articles on climate-related topics are widely referenced by policymakers, media outlets, and academia. Despite the site's strong influence on public understanding of science, few geoscientists actively participate in Wikipedia, with the result that the community that edits these articles is mostly composed of individuals with little or no expertise in the topic at hand. In this presentation we discuss how geoscientists can help shape public understanding of science by contributing to Wikipedia. Although Wikipedia prides itself on being "the encyclopedia that anyone can edit," the site has policies regarding contributions and behavior that can be pitfalls for newcomers. This presentation is intended as a guide for the geoscience community in contributing to information about climate change in this widely-used reference.

  4. Climate change and nuclear power

    Energy Technology Data Exchange (ETDEWEB)

    Schneider, M

    2000-04-01

    The nuclear industry has increased its efforts to have nuclear power plants integrated into the post- Kyoto negotiating process of the UN Framework Convention on Climate Change. The Nuclear Energy Institute (NEI) states: ''For many reasons, current and future nuclear energy projects are a superior method of generating emission credits that must be considered as the US expands the use of market- based mechanisms designed around emission credit creation and trading to achieve environmental goals ''. The NEI considers that nuclear energy should be allowed to enter all stages of the Kyoto ''flexibility Mechanisms'': emissions trading, joint implementation and the Clean Development Mechanism. The industry sees the operation of nuclear reactors as emission ''avoidance actions'' and believes that increasing the generation of nuclear power above the 1990 baseline year either through extension and renewal of operating licenses or new nuclear plant should be accepted under the flexibility mechanisms in the same way as wind, solar and hydro power. For the time being, there is no clear definition of the framework conditions for operating the flexibility mechanisms. However, eligible mechanisms must contribute to the ultimate objective of the Climate Convention of preventing ''dangerous anthropogenic interference with the climate system''. The information presented in the following sections of this report underlines that nuclear power is not a sustainable source of energy, for many reasons. In conclusion, an efficient greenhouse gas abatement strategy will be based on energy efficiency and not on the use of nuclear power. (author)

    The resurgence of audio programming with the advent of podcasting in the early 2000s spawned a new medium for communicating advances in science, research, and technology. To capitalize on this informal educational outlet, the Arctic Institute of North America partnered with the International Arctic Research Center, the University of Alaska Fairbanks, and the UA Museum of the North to develop a podcast series called PoLAR Voices for the Polar Learning and Responding (PoLAR) Climate Change Education Partnership. PoLAR Voices is a public education initiative that uses creative storytelling and novel narrative structures to immerse the listener in an auditory depiction of climate change. The programs will feature the science and story of climate change, approaching topics from both the points of view of researchers and Arctic indigenous peoples. This approach will engage the listener in the holistic story of climate change, addressing both scientific and personal perspectives, resulting in a program that is at once educational, entertaining and accessible. Feedback is being collected at each stage of development to ensure the content and format of the program satisfies listener interests and preferences. Once complete, the series will be released on thepolarhub.org and on iTunes. Additionally, blanket distribution of the programs will be accomplished via radio broadcast in urban, rural and remote areas, and in multiple languages to increase distribution and enhance accessibility.

    International Nuclear Information System (INIS)

    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)

  7. Air Quality and Climate Change

    International Nuclear Information System (INIS)

    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 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)

  9. Climate Change and Migration in the MENA Region: An Overview

    Climate change and migration are major concerns in the MENA region, yet the empirical evidence on the impact of climate change and extreme weather events on migration remains limited. Information is broadly lacking on how households in vulnerable areas perceive changes in the climate, how they are affected by extreme weather events, whether they benefit from community and government programs to help them cope with and adapt to a changing climate, and how these conditions influence the decisio...

    This paper documents rural households' perceptions of and responses to hailstorms and drought, which have been increasingly common in southwest China. This is important as the current coping behaviour serves as a starting point for future adaptations. Primary data were collected from 162 households...... found across villages regarding the degree of perceived sensitivity and responses despite similar exposure to climate extremes. These differences are partly related to the nature of events and varied socio-economic characteristics of households, which influence their vulnerability and ability to cope...

  12. Late Quaternary changes in climate

    International Nuclear Information System (INIS)

    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

  14. Climate change. Managing the risks

    International Nuclear Information System (INIS)

    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-CO2 greenhouse gases are dealt with subsequently. The dissertation ends with general conclusions and recommendations for the further design of a targeted approach to climate change response, the development of analytical tools to support policy development in the area of climate change, and strategies that are consistent with preliminary long-term environmental goals. 66 figs., 8 tabs., 417 refs., 1 appendix

    The University of Texas at San Antonio (UTSA), San Antonio College (SAC), and the University of North Dakota (UND) have partnered with NASA to provide underrepresented undergraduates from UTSA, SAC, and other community colleges climate-related research and education experiences through the Climate Change Communication: Engineer, Environmental science, and Education (C3E3) project. The program aims to develop a robust response to climate change by providing K-16 climate change education; enhance the effectiveness of K-16 education particularly in engineering and other STEM disciplines by use of new instructional technologies; increase the enrollment in engineering programs and the number of engineering degrees awarded by showing engineering's usefulness in relation to the much-discussed contemporary issue of climate change; increase persistence in STEM degrees by providing student research opportunities; and increase the ethnic diversity of those receiving engineering degrees and help ensure an ethnically diverse response to climate change. Students participated in the second summer internship funded by the project. The program is in its third year. More than 75 students participated in a guided research experiences aligned with NASA Science Plan objectives for climate and Earth system science and the educational objectives of the three institutions. The students went through training in modern media technology (webcasts), and in using this technology to communicate the information on climate change to others, especially high school students, culminating in production of webcasts on investigating the aspects of climate change using NASA data. Content developed is leveraged by NASA Earth observation data and NASA Earth system models and tools. Three Colleges were involved in the program: Engineering, Education, and Science.

  16. Confronting climate change

    International Nuclear Information System (INIS)

    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

    On Monday, June 12, the federal government released a "Public Review Draft" of Climate Change Impacts on the United States (1). The report contains peer-reviewed information that should be of interest to the general public and certainly will make excellent summer reading for those of us who teach chemistry or other sciences. The U.S. Global Change Research Project (USGCRP), was initiated in 1990 by the U.S. Congress to provide lawmakers with information about negative and positive impacts of global warming. In 1997, USGCRP began the National Assessment of the Potential Consequences of Climate Variability and Change. Five teams, each consisting of experts from government, industry, and academic and public organizations, used sophisticated computer models to analyze regional impacts of climate change and prepare a national synthesis of existing information. They forecast significant changes during the 21st century, including an increase in temperature in the U.S. of 3-6 °C. (This is similar to the difference in temperature between the present and the last ice age.) Many regions of the country are likely to become more like the regions immediately to their south. For example, the climate in New York City is predicted to become more like the 20th-century climate of Atlanta, and Atlanta more like Houston.

  18. Ocean Observations of Climate Change

    Science.gov (United States)

    Chambers, Don

    2016-01-01

    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.

  20. Climatic change and insect outbreaks

    International Nuclear Information System (INIS)

    Insects represent the dominant natural disturbance factor in Canada's forests. Host trees are often killed over extensive areas. This paper examines how climate change may influence insect outbreak regimes in Canada's forests, primarily focusing on temperature, as the potential rate of increase of many insects is dependent on temperature. The extent and frequency of temperature extremes can have major impacts on insect populations. Temperature increases will accelerate development, activity and movement as well as influence reduced mortality from climatic factors. In addition, higher temperatures are likely to facilitate extended periods of activity at both ends of the season. It was concluded that a number of complex factors will likely determine the direct effect of increasing temperatures on insects. Changes in the abiotic environment, changes in species interactions, and changes in the regimes of natural selection will influence future insect activity. For example, increases in carbon:nitrogen ratios are expected to cause insects to eat more in order to maintain dietary nitrogen. The effects of climate change is expected to differ quantitatively among species in the complex food chains where most insect species are embedded. It is also assumed that if geographic distribution of insects shifts in response to climate change, their impact should basically remain static. Most published scenarios suggest that outbreaks of insects in Canada will last longer and occur more frequently where the climate will become warmer. However, climate warming may also allow certain insects to extend their ranges into regions of vulnerable host species. It was suggested that further research is necessary, as no data has been collected on how insects might respond to predicted, concurrent changes in atmospheric chemistry and climate. 19 refs

  2. Climate change and shareholder value

    International Nuclear Information System (INIS)

    During 2005, the Carbon Trust worked with Cairneagle Associates to develop a methodology for analysing shareholder value at risk from climate change. The model developed offers a robust, replicable, top-down approach to analysing such value at risk. In addition to a company's own energy linked ('direct' and electricity linked 'indirect') carbon emissions, it looks further along the value chain and considers broader potential risk. In calculating the financial impact, the analysis quantifies the potential impact on profits, using the shape of the business in 2004, but applying a potential 2013 emissions regulatory regime. 2013 was chosen as the first year after the end of the 2008-2012 Kyoto compliance period (which also equates to Phase Two in the EU Emissions Trading Scheme). A major uncertainty is to what extent countries not currently regulated by the Kyoto Protocol (particularly the USA, India and China) will be brought into committed emission reduction targets from 2013. 2013 therefore represents the earliest year under this uncertain, but likely tougher, regulatory regime. However, although this report focuses on 2013, it needs to be recognised that, for many sectors, financial impacts will be seen significantly before this time. Ten 'case study companies' have been studied, from a range of sectors. In some cases, the 'case study company' analysed is strictly linked to a single company within that sector. In others, just a single corporate division has been reviewed, and in others yet again, characteristics from several companies have been combined to produce a more representative example. In order to enable analysis on a strictly like-for-like basis, the research has been based entirely upon public sources of information. This analysis illustrates what a determined shareholder (or other onlooker) could derive about value at risk from climate change, based upon what companies disclose today. A summary of the analysis for each sector case study is given, with

  3. Landcare and climate change: a regional perspective

    International Nuclear Information System (INIS)

    Full text: Full text: Bass Coast in Victoria represents a microcosm of the wide range of issues on which climate change will impact. It is experiencing rapid demographic change as sea and tree change populations increase, it adjoins the urban fringe of Melbourne, it includes Victoria's most popular eco-tourism and other recreational tourism areas, and it continues to be an important agricultural production area. The area has been one of the most reliable climate zones in Australia, but it is predicted to be one of the most affected by climate change. Landcare is a community-based, government and corporate-funded national organisation established for over twenty years. Landcare has been responsible for developing a positive attitude to sustainable and productive land management and implementing landscape scale environmental improvement. In Bass Coast it faces a broad range of problems related to climate change and it suffers from a scarcity of science-based information on which to base strategic direction. Given the very long-term nature of climate change and the equally long-term nature of Bass Coast Landcare Network environmental programs, it is essential to have more evidence based information and the need is urgent. Examples: Vegetation species for future climate and robustness of indigenous vegetation; Water supplies for livestock and wildlife while maintaining environmental flows; Salinity issues, soil structure and health issues; Testing and extending changed farming practices as seasons change Specific research/information needs: Growth rates at higher C02, especially woody weeds; Assessment of evaporation prevention options for farm dams (urgently needed); Options for harvesting stormwater and storage for both agriculture and wildlife use; A flexible and simple template for objectively assessing the costs and benefits of changing farming practices; Localised information on likely reduction in run-off under lower rainfall conditions.

  4. Climate Change as a Predictable Surprise

    International Nuclear Information System (INIS)

    In this article, I analyze climate change as a 'predictable surprise', an event that leads an organization or nation to react with surprise, despite the fact that the information necessary to anticipate the event and its consequences was available (Bazerman and Watkins, 2004). I then assess the cognitive, organizational, and political reasons why society fails to implement wise strategies to prevent predictable surprises generally and climate change specifically. Finally, I conclude with an outline of a set of response strategies to overcome barriers to change

    The Mediterranean has been identified as a potentially vulnerable hotspot under climate change. In Turkey, climate change projections consistently predict large temperature rises over the 21st century. With 9% of GDP and 25% of employment coming from agriculture, climate change has the potential to significantly affect both the Turkish economy and living standards. Relatively little work has been undertaken to estimate the effects and risks of climate change in Turkey, and many European studies cover do not include the whole of Turkey in their domain and so are of limited use for policy-makers. The Dynamic Global Vegetation Model LPJ-GUESS was parametrised to represent Turkish vegetation. Climate forcings were derived by interpolating meteorological data from over 600 stations from 1975-2010 to a 1km resolution. Soil depth and soil texture data from field measurements were also interpolated to a 1km grid. The model was benchmarked against vegetation type and remotely sensed biomass and tree cover data. Future climate conditions were calculated using the outputs from a set of regional model simulations. In particular the HadRM3P regional climate model was used to downscale five members of a perturbed physics ensemble of global climate projections obtained using HadCM3 general circulation model and the SRES A1B scenario. A delta change factor approach was then used in conjunction with the observed climate data to assess the impact on vegetation structure and ecological processes to the year 2100 using LPJ-GUESS. The resulting changes to productivity, vegetation structure and hydrology are discussed. Eventually these results will be combined with complementary studies concerning wildfire and erosion to produce a risk map for informing policy-makers.

  6. Understanding the school 'climate': secondary school children and climate change

    International Nuclear Information System (INIS)

    This interdisciplinary study analyzes the production, circulation and reception of messages on climate change in secondary schools in France. The objective is to understand how political and educational policy initiatives influence the ways in which schools contribute to creating youngsters' perceptions and opinions about climate change. 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

  7. The climate crisis: An introductory guide to climate change

    Science.gov (United States)

    Trenberth, Kevin E.

    2011-06-01

    Human-induced climate change, sometimes called “global warming,” has, unfortunately, become a “hot” topic, embroiled in controversy, misinformation, and claims and counterclaims. It should not be this way, because there are many scientific facts that provide solid information on which to base policy. There is a very strong observational, theoretical, and modeling base in physical science that underpins current understanding of what has happened to Earth's climate and why and what the prospects are for the future under certain assumptions. Moreover, these changes have impacts, which are apt to grow, on the environment and human society. To avoid or reduce these impacts and the economic and human effects of undesirable future climate change requires actions that are strongly opposed by those with vested interests in the status quo, some of whom have funded misinformation campaigns that have successfully confused the public and some politicians, leading to paralysis in political action. Without mitigation of climate change, one would suppose that at least society would plan sensibly for the changes already happening and projected, but such future adaptation plans are also largely in limbo. The implication is that we will suffer the consequences. All of these aspects are addressed in this informative and attractive book, which is written for a fairly general but technically informed audience. The book is strongly based upon the 2007 Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change (IPCC) and therefore has a solid scientific basis. Many figures, graphs, and maps come from the three IPCC working group reports, although the captions often do not explain the detail shown. Given that the IPCC reports totaled nearly 3000 pages, to distill the complex material down to 249 pages is no mean task, and the authors have succeeded quite well.

  8. iSeeChange: Crowdsourced Climate Change Reporting

    Science.gov (United States)

    Drapkin, J. K.

    2012-12-01

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

  13. Climate change: where to now?

    International Nuclear Information System (INIS)

    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

  14. 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.

  15. Dislocated interests and climate change

    Science.gov (United States)

    Davis, Steven J.; Diffenbaugh, Noah

    2016-06-01

    The predicted effects of climate change on surface temperatures are now emergent and quantifiable. The recent letter by Hansen and Sato (2016 Environ. Res. Lett. 11 034009) adds to a growing number of studies showing that warming over the past four decades has shifted the distribution of temperatures higher almost everywhere, with the largest relative effects on summer temperatures in developing regions such as Africa, South America, southeast Asia, and the Middle East (e.g., Diffenbaugh and Scherer 2011 Clim. Change 107 615–24 Anderson 2011 Clim. Change 108 581; Mahlstein et al 2012 Geophys. Res. Lett. 39 L21711). Hansen and Sato emphasize that although these regions are warming disproportionately, their role in causing climate change—measured by cumulative historical CO2 emissions produced—is small compared to the US and Europe, where the relative change in temperatures has been less. This spatial and temporal mismatch of climate change impacts and the burning of fossil fuels is a critical dislocation of interests that, as the authors note, has ‘substantial implications for global energy and climate policies.’ Here, we place Hansen and Sato’s ‘national responsibilities’ into a broader conceptual framework of problematically dislocated interests, and briefly discuss the related challenges for global climate mitigation efforts.

    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 northern-most 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. In this context, four iconic river basins offer glimpses into specific challenges that climate change may bring to the West. The Colorado River is a system in which overuse and growing demands are projected to be even more challenging than climate-change-induced flow reductions. The Rio Grande offers the best example of how climate-change-induced flow declines might sink a major system into permanent drought. The Klamath is currently projected to face the more benign precipitation future, but fisheries and irrigation management may face dire straits due to warming air temperatures, rising irrigation demands, and warming waters in a basin already hobbled by tensions between endangered fisheries

    Central America has high biodiversity, it harbors high-value ecosystems and it's important to provide regional climate change information to assist in adaptation and mitigation work in the region. Here we study climate change projections for Central America and Mexico using a regional climate model. The model evaluation shows its success in simulating spatial and temporal variability of temperature and precipitation and also in capturing regional climate features such as the bimodal annual cycle of precipitation and the Caribbean low-level jet. A variety of climate regimes within the model domain are also better identified in the regional model simulation due to improved resolution of topographic features. Although, the model suffers from large precipitation biases, it shows improvements over the coarse-resolution driving model in simulating precipitation amounts. The model shows a dry bias in the wet season and a wet bias in the dry season suggesting that it's unable to capture the full range of precipitation variability. Projected warming under the A2 scenario is higher in the wet season than that in the dry season with the Yucatan Peninsula experiencing highest warming. A large reduction in precipitation in the wet season is projected for the region, whereas parts of Central America that receive a considerable amount of moisture in the form of orographic precipitation show significant decreases in precipitation in the dry season. Projected climatic changes can have detrimental impacts on biodiversity as they are spatially similar, but far greater in magnitude, than those observed during the El Nino events in recent decades that adversely affected species in the region.

  1. The emerging climate change regime

    International Nuclear Information System (INIS)

    The emerging climate change regime--with the UN Framework Convention on Climate Change (FCCC) at its core--reflects the substantial uncertainties, high stakes and complicated politics of the greenhouse warming issue. The regime represents a hedging strategy. On the one hand, it treats climate change as a potentially serious problem, and in response, creates a long-term, evolutionary process to encourage further research, promote national planning, increase public awareness, and help create a sense of community among states. But it requires very little by way of substantive--and potentially costly--mitigation or adaptation measures. Although the FCCC parties have agreed to negotiate additional commitments, substantial progress is unlikely without further developments in science, technology, and public opinion. The FCCC encourages such developments, and is capable of evolution and growth, should the political will to take stronger international action emerge. 120 refs., 3 tabs

  2. EU focus on climate change

    International Nuclear Information System (INIS)

    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

  4. Climate change adaptation strategies and mitigation policies

    Science.gov (United States)

    García Fernández, Cristina

    2015-04-01

    The pace of climate change and the consequent warming of the Earth's surface is increasing vulnerability and decreasing adaptive capacity. Achieving a successful adaptation depends on the development of technology, institutional organization, financing availability and the exchange of information. Populations living in arid and semi-arid zones, low-lying coastal areas, land with water shortages or at risk of overflow or small islands are particularly vulnerable to climate change. Due to increasing population density in sensitive areas, some regions have become more vulnerable to events such as storms, floods and droughts, like the river basins and coastal plains. Human activities have fragmented and increased the vulnerability of ecosystems, which limit both, their natural adaptation and the effectiveness of the measures adopted. Adaptation means to carry out the necessary modifications for society to adapt to new climatic conditions in order to reduce their vulnerability to climate change. Adaptive capacity is the ability of a system to adjust to climate change (including climate variability and extremes) and to moderate potential damages, to take advantage of opportunities or face the consequences. Adaptation reduces the adverse impacts of climate change and enhance beneficial impacts, but will not prevent substantial cost that are produced by all damages. The performances require adaptation actions. These are defined and implemented at national, regional or local levels since many of the impacts and vulnerabilities depend on the particular economic, geographic and social circumstances of each country or region. We will present some adaptation strategies at national and local level and revise some cases of its implementation in several vulnerable areas. However, adaptation to climate change must be closely related to mitigation policies because the degree of change planned in different climatic variables is a function of the concentration levels that are achieved

  7. Position Statement On Climate Change.

    2016-05-01

    The North Carolina Environmental Justice Network (NCEJN), a coalition of grassroots organizations, developed a statement to explain our environmental justice perspective on climate change to predominantly white environmental groups that seek to partner with us. NCEJN opposes strategies that reduce greenhouse emissions while maintaining or magnifying existing social, economic, and environmental injustices. Wealthy communities that consume a disproportionate share of resources avoid the most severe consequences of their consumption by displacing pollution on communities of color and low income. Therefore, the success of climate change activism depends on building an inclusive movement based on principles of racial, social and economic justice, and self-determination for all people.

  9. Changing habits, changing climate : a foundation analysis

    International Nuclear Information System (INIS)

    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

    Climate change is likely to lead to increasing population variability and extinction risk. Theoretically, greater population diversity should buffer against rising climate variability, and this theory is often invoked as a reason for greater conservation. However, this has rarely been quantified. Here we show how a portfolio approach to managing population diversity can inform metapopulation conservation priorities in a changing world. We develop a salmon metapopulation model in which productivity is driven by spatially distributed thermal tolerance and patterns of short- and long-term climate change. We then implement spatial conservation scenarios that control population carrying capacities and evaluate the metapopulation portfolios as a financial manager might: along axes of conservation risk and return. We show that preserving a diversity of thermal tolerances minimizes risk, given environmental stochasticity, and ensures persistence, given long-term environmental change. When the thermal tolerances of populations are unknown, doubling the number of populations conserved may nearly halve expected metapopulation variability. However, this reduction in variability can come at the expense of long-term persistence if climate change increasingly restricts available habitat, forcing ecological managers to balance society's desire for short-term stability and long-term viability. Our findings suggest the importance of conserving the processes that promote thermal-tolerance diversity, such as genetic diversity, habitat heterogeneity, and natural disturbance regimes, and demonstrate that diverse natural portfolios may be critical for metapopulation conservation in the face of increasing climate variability and change.

  12. Sustain : the climate change challenge

    International Nuclear Information System (INIS)

    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. Emissions trading' and 'joint implementation' are seen as two important tools to tackle climate change on a global basis. 4 figs

  13. The adaptation to climate change

    International Nuclear Information System (INIS)

    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

    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.

  15. The economics of climate change

    International Nuclear Information System (INIS)

    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)

    The paper discusses aspects of the implementation of the program for climatic change which has been come about as part of the U.N. Framework Convention on Climate Change. Initial effort has focused on providing strategic information and help to countries, on achieving offsets in greenhouse gas emissions by energy conservation or carbon sinking, and an emphasis on development of renewable energy supplies. The U.N. Development Agency has limited funding to help support startup on projects submitted. Specific examples are discussed in the areas of energy conservation and energy efficiency, adoption of renewable energy sources, and reducing the long-term costs of low greenhouse gas-emitting energy technologies.

    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.

    There is a growing recognition that mitigation measures for limiting future global changes in climate due to the enhanced greenhouse effect are unlikely to prevent some changes from occurring. Thus, if climate changes appear to be unavoidable, there is an increased need to evaluate their likely impacts on natural systems and human activities. Most impacts of climate change need to be examined at a regional scale, and their assessment requires up-to-date information on future regional climate changes. Unfortunately, accurate predictions of regional climate are not yet available. Instead, it is customary to construct climatic scenarios, which are plausible representations of future climate based on the best available information.

    Changing climatic, demographic, and land use conditions are projected to alter the provisioning of ecosystem services in estuarine, coastal, and nearshore marine ecosystems, necessitating mitigation and adaptation policies and management. The current paradigm of research efforts occurring in parallel to, rather than in collaboration with, decision makers will be insufficient for the rapid responses required to adapt to and mitigate for projected changing conditions. Here, we suggest a different paradigm: one where research begins by engaging decision makers in the identification of priority data needs (biophysical, economic, and social). This paper uses synthesized interview data to provide insight into the varied demands for scientific research as described by decision makers working on coastal issues in Oregon, USA. The findings highlight the need to recognize (1) the differing framing of ecosystem services by decision makers versus scientists; and (2) the differing data priorities relevant to inland versus coastal decision makers. The findings further serve to highlight the need for decision makers, scientists, and funders to engage in increased communication. This research is an important first step in advancing efforts toward evidence-based decision making in Oregon and provides a template for further research across the US.

    Permanently frozen soil, or permafrost, covers a large portion of the Earth's terrestrial surface and represents a unique environment for cold-adapted microorganisms. As permafrost thaws, previously protected organic matter becomes available for microbial degradation. Microbes that decompose soil carbon produce carbon dioxide and other greenhouse gases, contributing substantially to climate change. Next-generation sequencing and other -omics technologies offer opportunities to discover the mechanisms by which microbial communities regulate the loss of carbon and the emission of greenhouse gases from thawing permafrost regions. Analysis of nucleic acids and proteins taken directly from permafrost-associated soils has provided new insights into microbial communities and their functions in Arctic environments that are increasingly impacted by climate change. In this article we review current information from various molecular -omics studies on permafrost microbial ecology and explore the relevance of these insights to our current understanding of the dynamics of permafrost loss due to climate change.

    Approximately 10 per cent of greenhouse gas (GHG) emissions result from agricultural production activities. This report assessed the level of understanding that farmers have on the issue of climate change and GHG emissions. It also examined the impact that their decisions have on soil, land, and livestock management. This information is intended to assist governments and industry in the development of policies aimed at meeting Canada's commitments under the Kyoto Protocol. In January-February of 2001, Leger Marketing conducted interviews with 1,643 producers from across Canada whose main farm type was field crops, beef cattle, dairy, hogs or poultry and whose annual gross farm revenues exceeded $10,000. The objective was to determine the farmers' level of awareness of climate change issues and GHG emissions in agriculture. The results of the survey indicated that producers generally do not understand how the agricultural sector contributes to climate change and GHG emissions. 5 tabs., 39 figs.

    Climate change poses multiple risks to the population of Lima, the largest city and capital of Peru, located on the Pacific coast in a desert ecosystem. These risks include increased water scarcity, increased heat, and the introduction and emergence of vector-borne and other climate sensitive diseases. To respond to these threats, it is necessary for the government, at every level, to adopt more mitigation and adaptation strategies. Here, focus groups were conducted with representatives from five Lima municipalities to determine priorities, perception of climate change, and decision-making processes for implementing projects within each municipality. These factors can affect the ability and desire of a community to implement climate change adaptation and mitigation strategies. The results show that climate change and other environmental factors are of relatively low priority, whereas public safety and water and sanitation services are of highest concern. Perhaps most importantly, climate change is not well understood among the municipalities. Participants had trouble distinguishing climate change from other environmental issues and did not fully understand its causes and effects. Greater understanding of what climate change is and why it is important is necessary for it to become a priority for the municipalities. Different aspects of increased climate change awareness seem to be connected to having experienced extreme weather events, whether related or not to climate change, and to higher socioeconomic status.

  7. Emergency Managers Confront Climate Change

    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. PMID:27300144

    International Nuclear Information System (INIS)

    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

    Full Text Available There has been a growing attention on the need to take into account the effects of global climate change. This is particularly so with respect to the increasing amount of green house gas emissions from the Untied States and Europe affecting poor peoples, especially those in developing countries. In 2003, for example, the experts of several international development agencies, including the World Bank, prepared a special report titled “Poverty and Climate Change: Reducing the Vulnerability of the Poor through Adaptation” (OECD 2003. This report followed the Eighth Session of the Conference of Parties (COP8 to the United Nations Framework Convention on Climate Change (UNFCCC in New Delhi, India in October 2002. It showed that poverty reduction is not only one of the major challenges of the 21st century, but also that climate change is taking place in many developing countries and is increasingly affecting, in a negative fashion, both the economic conditions and the health of poor people and their communities.

    Climate change is generating novel communities composed of new combinations of species. These result from different degrees of species adaptations to changing biotic and abiotic conditions, and from differential range shifts of species. To determine whether the responses of organisms are determined by particular species traits and how species interactions and community dynamics are likely to be disrupted is a challenge. Here, we focus on two key traits: body size and ecological specialization...

  1. Climate Change and Intertidal Wetlands

    Directory of Open Access Journals (Sweden)

    Pauline M. Ross

    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 Workshop on Uncertainty and Global Climate Change Research March 22--23, 1994, in Knoxville, Tennessee. This report summarizes the results and recommendations of the workshop. The purpose of the workshop was to examine in-depth the concept of uncertainty. From an analytical point of view, uncertainty is a central feature of global climate science, economics and decision making. The magnitude and complexity of uncertainty surrounding global climate change has made it quite difficult to answer even the most simple and important of questions-whether potentially costly action is required now to ameliorate adverse consequences of global climate change or whether delay is warranted to gain better information to reduce uncertainties. A major conclusion of the workshop is that multidisciplinary integrated assessments using decision analytic techniques as a foundation is key to addressing global change policy concerns. First, uncertainty must be dealt with explicitly and rigorously since it is and will continue to be a key feature of analysis and recommendations on policy questions for years to come. Second, key policy questions and variables need to be explicitly identified, prioritized, and their uncertainty characterized to guide the entire scientific, modeling, and policy analysis process. Multidisciplinary integrated assessment techniques and value of information methodologies are best suited for this task. In terms of timeliness and relevance of developing and applying decision analytic techniques, the global change research and policy communities are moving rapidly toward integrated approaches to research design and policy analysis.

  3. Northern peatlands in global climatic change

    Northern peatlands are important in regulating the global climate. While sequestering carbon dioxide, these peatlands release ca. 24-39 Tg methane annually to the atmosphere. This is 5-20 % of the annual anthropogenic methane emissions to the atmosphere. The greenhouse gas balance of peatlands may change as a consequence of water level draw-down after land-use change, or if summers become warmer and drier, as has been predicted for high latitudes after climatic warming. Subsequent emissions of methane would decrease, whereas emissions of carbon dioxide and nitrous oxide would increase. Within the Finnish Research Programme on Climate Change (SILMU), the research project `Carbon Balance of Peatlands and Climate Change` (SUOSILMU) has been under progress since 1990. It is a co-operative research project, with research groups from the Universities of Helsinki and Joensuu, the Finnish Forest Research Institute, the National Public Health Institute and the Finnish Environment Agency. The research consortium of this project organised a workshop entitled `Northern Peatlands in Global Climatic Change - Hyytiaelae Revisited` October 8-12, 1995. The main objective of the workshop was to review the state of the art of the carbon cycling research in natural and managed peatlands. The role of peatlands in the greenhouse effect, their response and feedback to the predicted climate change, and the consequences of land-use changes were assessed, and the future research needs were evaluated. The latest information on the role of peatlands in the atmospheric change was given in 50 posters and 4 key lectures. Results of SUOSILMU projects were demonstrated during a 1-day field excursion to one of the intensive study sites, Lakkasuo near Hyytiaelae

  4. Capturing Tweets on Climate Change: What is the role of Twitter in Climate Change Communication?

    2015-12-01

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

    The research in this thesis focuses on the impacts of and adaptation to present variations in climate and to projected future changes. The research has dealt with different levels, i.e. household/community, national/policymaking, and sectoral level, to show different perspectives of the implications of climate variability and change to development. In particular, it focuses on how present variations in rainfall patterns affect rural households, ways to strengthen households' resilience to climate variability, and the costs and benefits of adaptation measures. The research attempts to contribute to the knowledge that informs the development community and national governments for policy-making on the implications of climate change on development planning and strategies. It is argued in the thesis that it is essential for sustainable development to mainstream climate change into strategies and planning where relevant. To do this a knowledge of the costs and benefits of diverse adaptation measures is essential. Fluctuations in annual and seasonal rainfall, both in terms of modest and excessive rains, are found to cause negative shocks to rural household incomes in the Kagera a region of Tanzania. An analysis of rainfall and household data for the region shows large local discrepancies in the distribution of rainfall, as well as in households reporting shocks to income caused by harvest failure. It is also evident from the research results that the timing of rainfall seems to play a greater role than the level of annual precipitation. The coping strategies that households report following subsequent to a harvest failure further show local divergence in the choice of, for example, taking casual employment and relying on support from others in the form of informal networks. These results support earlier work which points in the same direction and emphasizes that policies should be targeted to local specificities. This provides a great motivation for targeted

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

    International Nuclear Information System (INIS)

    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

    In its first part, this report discusses the Lima agreement with questions left to be answered in Paris, and large divergences. It also comments the issue of national contributions and its process which has been adopted in Lima, and highlights the shortcomings of the Lima call. Then, it discusses progresses related to the creation of a Green Fund, and outlines uncertainties for the period 2015-2020. In the second part, it describes and discusses stakes and challenges faced by the Paris conference: the importance of a legally constraining treaty, the necessity of higher level of ambition regarding mitigation, the essential guarantee of control and transparency, the attention paid to the adaptation of the most vulnerable countries, and the need of a sufficient and sustainable financing. The third part addresses the situation and role of the European Union within international negotiations on climate change: position of the EU and of the European Parliament regarding the COP21, publications by Eurostat to assess and measure advances made by the EU. It also addresses the uncertain conciliation with other important interveners like the USA, China, the G7 and the G20

  8. Precipitation extremes under climate change

    O'Gorman, Paul A

    2015-01-01

    The response of precipitation extremes to climate change is considered using results from theory, modeling, and observations, with a focus on the physical factors that control the response. Observations and simulations with climate models show that precipitation extremes intensify in response to a warming climate. However, the sensitivity of precipitation extremes to warming remains uncertain when convection is important, and it may be higher in the tropics than the extratropics. Several physical contributions govern the response of precipitation extremes. The thermodynamic contribution is robust and well understood, but theoretical understanding of the microphysical and dynamical contributions is still being developed. Orographic precipitation extremes and snowfall extremes respond differently from other precipitation extremes and require particular attention. Outstanding research challenges include the influence of mesoscale convective organization, the dependence on the duration considered, and the need to...

    The selection of climate policies should be an exercise in risk management reflecting the many relevant sources of uncertainty. Studies of climate change and its impacts rarely yield consensus on the distribution of exposure, vulnerability or possible outcomes. Hence policy analysis cannot effectively evaluate alternatives using standard approaches, such as expected utility theory and benefit-cost analysis. This Perspective highlights the value of robust decision-making tools designed for situations such as evaluating climate policies, where consensus on probability distributions is not available and stakeholders differ in their degree of risk tolerance. A broader risk-management approach enables a range of possible outcomes to be examined, as well as the uncertainty surrounding their likelihoods.

  10. Climate change and energy demand

    International Nuclear Information System (INIS)

    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

  12. The ACPI Climate Change Simulations

    International Nuclear Information System (INIS)

    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

    2013-11-19

    Climate Information Needs for Financial Decision Making (Final Report) This Department of Energy workshop award (grant #DE-SC0008480) provided primary support for the American Meteorological Society’s study on climate information needs for financial decision making. The goal of this study was to help advance societal decision making by examining the implications of climate variability and change on near-term financial investments. We explored four key topics: 1) the conditions and criteria that influence returns on investment of major financial decisions, 2) the climate sensitivity of financial decisions, 3) climate information needs of financial decision makers, and 4) potential new mechanisms to promote collaboration between scientists and financial decision makers. Better understanding of these four topics will help scientists provide the most useful information and enable financial decision makers to use scientific information most effectively. As a result, this study will enable leaders in business and government to make well-informed choices that help maximize long-term economic success and social wellbeing in the United States The outcomes of the study include a workshop, which brought together leaders from the scientific and financial decision making communities, a publication of the study report, and a public briefing of the results to the policy community. In addition, we will present the results to the scientific community at the AMS Annual Meeting in February, 2014. The study results were covered well by the media including Bloomberg News and E&E News. Upon request, we also briefed the Office of Science Technology Policy (OSTP) and the Council on Environmental Quality (CEQ) on the outcomes. We presented the results to the policy community through a public briefing in December on Capitol Hill. The full report is publicly available at www.ametsoc.org/cin.

    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. PMID:18991898

    International Nuclear Information System (INIS)

    'Climate change - the commitment of governments' is an authoritative information source for the energy policies of the OECO member states with regard to climate change. The publication descirbes the extent to which the individual countries have promised to lower their greenhouse gas emissions and by what political means they intend to fulfill their promises. It informs the reader on the resolutions of the Conference of the United Nations on Environment and Development and on the Framework Treaty Concerning the Climate Change. The publication is dedicated in particular to the extent to which national governments have committed themselves to stabilise or lower emissions and impose carbon or CO2 taxes. Each of the OECO states and the thirteen largest countries outside the OECO has been dedicated a chapter containing the official position of its government on the issue of climate change as well as references to the literature on relevant national studies. The picture of each country is rounded off by a presentation of its energy and CO2 emission data and indicators facilitating comparison. (orig.)

    2010-09-01

    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.

    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

    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

    2012-11-01

    Climate change is generating novel communities composed of new combinations of species. These result from different degrees of species adaptations to changing biotic and abiotic conditions, and from differential range shifts of species. To determine whether the responses of organisms are determined by particular species traits and how species interactions and community dynamics are likely to be disrupted is a challenge. Here, we focus on two key traits: body size and ecological specialization. We present theoretical expectations and empirical evidence on how climate change affects these traits within communities. We then explore how these traits predispose species to shift or expand their distribution ranges, and associated changes on community size structure, food web organization and dynamics. We identify three major broad changes: (i) Shift in the distribution of body sizes towards smaller sizes, (ii) dominance of generalized interactions and the loss of specialized interactions, and (iii) changes in the balance of strong and weak interaction strengths in the short term. We finally identify two major uncertainties: (i) whether large-bodied species tend to preferentially shift their ranges more than small-bodied ones, and (ii) how interaction strengths will change in the long term and in the case of newly interacting species.

    The New England Aquarium, collaborating with other aquariums across the country, is leading a national effort to enable aquariums and related informal science education institutions to effectively communicate the impacts of climate change and ocean acidification on marine animals, habitats and ecosystems. Our goal is to build on visitors' emotional connection with ocean animals, connect to their deeply held values, help them understand causes and effects of climate change and motivate them to embrace effective solutions. Our objectives are to: (1) Build a national coalition of aquariums and related informal education institutions collaborating on climate change education; (2) Develop an interpretive framework for climate change and the ocean that is scientifically sound, research-based, field tested and evaluated; and (3) Build capacity of aquariums to interpret climate change via training for interpreters, interactive exhibits and activities and communities of practice for ongoing support. Centers of informal learning have the potential to bring important environmental issues to the public by presenting the facts, explaining the science, connecting with existing values and interests, and motivating concern and action. Centers that work with live animals (including aquariums, zoos, nature centers, national parks, national marine sanctuaries, etc.) are unique in that they attract large numbers of people of all ages (over 140 million in the US), have strong connections to the natural, and engage many visitors who may not come with a primary interest in science. Recent research indicates that that the public expects and trusts aquariums, zoos, and museums to communicate solutions to environmental and ocean issues, and to advance ocean conservation, and that climate change is the environmental issue of most concern to the public; Ironically, however, most people do not associate climate change with ocean health, or understand the critical role that the ocean plays in

  7. Climatic change and security stakes

    International Nuclear Information System (INIS)

    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.

    2006-10-15

    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.

  10. Making sense of climate change

    International Nuclear Information System (INIS)

    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

    Economic trends have shaped our growth and the growth of the livestock sector, but atthe expense of altering natural resources and systems in ways that are not always obvious. Now, however, the reverse is beginning to happen, i.e. environmental trends are beginning to shape our economy and health status. In addition to water, air and food, animals and birds play a pivotal role in the maintenance and transmission of important zoonotic diseases in nature. It is generally considered that the prevalence of vector-borne and waterborne zoonoses is likely to increase in the coming years due to the effects of global warming in India. In recent years, vector-borne diseases have emerged as a serious public health problem in countries of the South-East Asia region, including India. Vector-borne zoonoses now occur in epidemic form almost on an annual basis, causing considerable morbidity and mortality. New reservoir areas of cutaneous leishmaniosis in South India have been recognised, and the role of climate change in its re-emergence warrants further research, as does the role of climate change in the ascendancy of waterborne and foodborne illness. Similarly, climate change that leads to warmer and more humid conditions may increase the risk of transmission of airborne zoonoses, and hot and drier conditions may lead to a decline in the incidence of disease(s). The prevalence of these zoonotic diseases and their vectors and the effect of climate change on important zoonoses in India are discussed in this review. PMID:22435190

High fertility spreads scarce household resources thin, resulting in children being poorly educated. At the macro level, technological progress is slow because of decreasing returns to scale in agriculture. With high populatio...

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

  17. Accounting for Climate Change: Introduction

    International Nuclear Information System (INIS)

    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

  18. Sustainable development and climatic change

    International Nuclear Information System (INIS)

    The relationships between the fight against climatic change and the objective of sustainable development have acquired an historical perspective: the Framework Convention of 1992, the Kyoto Protocol and the Bonn-Marrakech Accords. The Convention demonstrates that we must strive for economic growth and sustainable development to allow developing countries to better face the problems associated with climatic change. In the Kyoto Protocol, the commitments agreed upon by northern countries were presented as implicating a group of policies that promote sustainable development. The author discussed the challenges, the contradictions, and the means available to fight against climatic change since Rio. The author begins by expressing the hope that the Kyoto Protocol will be ratified at the Johannesburg Summit, since Russia is moving forward, despite the withdrawal of the United States. Scientists seem to agree that global warming is occurring due to the increase in greenhouse gases in the atmosphere. There are two major difficulties encountered in attempting to stabilize the levels of greenhouse gases: (1) are the countries that emit the most gases in a position to alter their activities in an effort to reduce emissions? and (2) will developing countries be able to avoid the pitfalls that led developed countries to emit greenhouse gases in enormous quantities?

    2013-01-01

    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.

    Climate change with global warming is a physicometeorological fact that, among other aspects, will also affect human health. Apart from cardiovascular and infectious diseases, allergies seem to be at the forefront of the sequelae of climate change. By increasing temperature and concomitant increased CO(2) concentration, plant growth is affected in various ways leading to prolonged pollination periods in the northern hemisphere, as well as to the appearance of neophytes with allergenic properties, e.g. Ambrosia artemisiifolia (ragweed), in Central Europe. Because of the effects of environmental pollutants, which do not only act as irritants to skin and mucous membranes, allergen carriers such as pollen can be altered in the atmosphere and release allergens leading to allergen-containing aerosols in the ambient air. Pollen has been shown not only to be an allergen carrier, but also to release highly active lipid mediators (pollen-associated lipid mediators), which have proinflammatory and immunomodulating effects enhancing the initiation of allergy. Through the effects of climate change in the future, plant growth may be influenced in a way that more, new and altered pollens are produced, which may affect humans. PMID:22433365

  1. Forestry Canada's perspectives on climate change

    International Nuclear Information System (INIS)

    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

    2012-12-01

    In order to broaden the public dialogue about climate change, climate scientists need to leverage the potential of informal science education and recent advances in social and cognitive science. In the US, more than 1,500 informal science venues (science centers, museums, aquariums, zoos, nature centers, national parks, etc.) are visited annually by 61% of the population. Extensive research shows that these visitors are receptive to learning about climate change and trust these institutions as reliable sources. Given that we spend less than 5% of our lifetime in a classroom, and only a fraction of that is focused on science, informal science venues will continue to play a critical role in shaping public understanding of environmental issues in the years ahead. Public understanding of climate change continues to lag far behind the scientific consensus not merely because the public lacks information, but because there is in fact too much complex and contradictory information available. Fortunately, we can now (1) build on careful empirical cognitive and social science research to understand what people already value, believe, and understand; and then (2) design and test strategies for translating complex science so that people can examine evidence, make well-informed inferences, and embrace science-based solutions. The New England Aquarium is leading a national effort to enable informal science education institutions to effectively communicate the impacts of climate change and ocean acidification on marine ecosystems. This NSF-funded partnership, the National Network for Ocean and Climate Change Interpretation (NNOCCI), involves the Association of Zoos and Aquariums, FrameWorks Institute, Woods Hole Oceanographic Institution, Monterey Bay Aquarium, and National Aquarium, with evaluation conducted by the New Knowledge Organization, Pennsylvania State University, and Ohio State University. We believe that skilled interpreters can serve as "communication strategists" by

The German Strategy for Adaptation emphasizes the meaning of information about requirements for adaptation and the active involvement of all social groups in the other process of the strategy. For this the research project has made concrete proposals for the information, communication and participation of social groups. These proposals are based in the essentials on an interest analysis about interviews with stakeholders and the economy to their demands and expectations to the German strategy for Adaptation. Besides we have researched international examples for the adaptation to the climate change for the public relations.

  9. Polar ices: rapid climatic changes

    International Nuclear Information System (INIS)

    The recent successes of the European GRIP (GReenland Ice core Project) and American GISP 2 (Greenland Ice Sheet Project) drillings which have reached in 1992 and 1993 the basement rocks of central Greenland (SUMMIT site, 3250 m of altitude) have allow to reconstruct the climate evolution for the last 100,000 years or more. A comparison of climatic informations deduced from these two drillings with records from Vostok (Antarctica) is given in this paper. The δD and δ18O isotopic approach have been used for the reconstruction of climatic series and paleotemperatures in polar regions. Empirical relationships explained by Rayleigh's isotopic models are used as a base for paleotemperature reconstructions from isotopic analyses of ice. A one degree Celsius cooling corresponds to an oxygen 18 decay of 0.67 per thousand and to a 6 per thousand deuterium decay. The GRIP and GISP 2 drillings have demonstrated the exceptional stability of Greenland climate during the last 10.000 years in comparison with strong instabilities encountered during the last 100.000 years and also recorded in North Atlantic marine sediments. The time scales associated with these instabilities are of the order of a few decades for the warming phase. Thanks to Vostok ice-trapped air bubbles analyses, it is now well demonstrated that the strongest instabilities (cooling during the last deglaciation and major glaciation inter stages) are also recorded but less pronounced in Antarctica. GRIP data for the last interglacial stage have been interpreted in terms of climate instabilities but neither GISP 2 results nor Vostok results allow to confirm this interpretation.

  10. Climate engineering and the risk of rapid climate change

    International Nuclear Information System (INIS)

    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.

    This report first outlines the urgency of struggle against global warming. It refers the scientific results recently published by the IPCC which notably worsened the diagnosis on global warming. It discussed the mixed results of the Doha Conference. In a second part, the authors discuss the stakes of the Warsaw climate Conference while outlining the need of a global agreement in 2015. For the Warsaw conference, the main identified issues are: to operate the green fund for climate and the technological mechanism, to finance aids to adaptation and to compensation of losses and damages, a better transparency and a greater ambition for emission reductions. The third part addresses the international struggle against global warming at the ICAO level (International Civil Aviation Organization), to reach a constraining agreement (top down versus bottom up approach), at the European Union level. The last part addresses the struggle against climate scepticism

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

    A complex debate is underway on climate change linked to proposals for costly measures that would reshape our power grid. This confronts technical experts outside of the geophysical disciplines with extensive, but unfamiliar, data both supporting and refuting claims that serious action is warranted. For example, evidence is brought to the table from one group of astrophysicists concerned with sunspots--this group believes there is no issue man can manage; while another group of oceanographers concerned with the heat balance in the world's oceans are very alarmed at the loss of arctic ice. What is the evidence? In an effort to put some of these issues in perspective for a technical audience, without a background in geophysics, a brief survey will consider (1) an overview of the 300 years of scientific inquiry on man's relationship to climate; (2) a basic discussion of what is meant by the ''greenhouse'' and why there are concerns which include not only CO{sub 2}, but also CH{sub 4}, N{sub 2}O, and CFC's; (3) the geological record on CO{sub 2}--which likely was present at 1,000 times current levels when life began; (4) the solar luminosity and sunspot question; and (5) the current evidence for global climate change. We are at a juncture where we are attempting to understand the earth as an integrated dynamic system, rather than a collection of isolated components.

    caused to be more accurate in their meta-perceptions than their disbelieving counterparts. Yet, even this group underestimates the public's concern about climate change and the presence of the false consensus effect suggests that greater accuracy is not a result of greater knowledge about other's beliefs but rather a result of personal cognitive or motivational biases counteracting a general trend toward underestimating the general public's concern. We conclude that there is need to inform the public about wide-spread agreement that human caused climate change and its impacts on oceans is believed by the majority of the public and to increase the public's confidence in climate scientist agreement about the existence, causes, and impacts of climate change.; Perceptions and metaperceptions of concern about climate change

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

    International Nuclear Information System (INIS)

    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

  2. Future change of daily precipitation indices in Japan: A stochastic weather generator-based bootstrap approach to provide probabilistic climate information

    2012-06-01

    This study proposes the stochastic weather generator (WG)-based bootstrap approach to provide the probabilistic climate change information on mean precipitation as well as extremes, which applies a WG (i.e., LARS-WG) to daily precipitation under the present-day and future climate conditions derived from dynamical and statistical downscaling models. Additionally, the study intercompares the precipitation change scenarios derived from the multimodel ensemble for Japan focusing on five precipitation indices (mean precipitation, MEA; number of wet days, FRE; mean precipitation amount per wet day, INT; maximum number of consecutive dry days, CDD; and 90th percentile value of daily precipitation amount in wet days, Q90). Three regional climate models (RCMs: NHRCM, NRAMS and TWRF) are nested into the high-resolution atmosphere-ocean coupled general circulation model (MIROC3.2HI AOGCM) for A1B emission scenario. LARS-WG is validated and used to generate 2000 years of daily precipitation from sets of grid-specific parameters derived from the 20-year simulations from the RCMs and statistical downscaling model (SDM: CDFDM). Then 100 samples of the 20-year of continuous precipitation series are resampled, and mean values of precipitation indices are computed, which represents the randomness inherent in daily precipitation data. Based on these samples, the probabilities of change in the indices and the joint occurrence probability of extremes (CDD and Q90) are computed. High probabilities are found for the increases in heavy precipitation amount in spring and summer and elongated consecutive dry days in winter over Japan in the period 2081-2100, relative to 1981-2000. The joint probability increases in most areas throughout the year, suggesting higher potential risk of droughts and excess water-related disasters (e.g., floods) in a 20 year period in the future. The proposed approach offers more flexible way in estimating probabilities of multiple types of precipitation extremes

  4. Using Global Geo-information for Disaster Risk Reduction Following the UN Sendai Framework: Climate Change and Disruptions to Global Fire Activity

    Ganz, D.

    2015-12-01

    Despite the knowledge that climate induced fire activity will threaten ecosystems and human well-being throughout the world, there are few fire projections at global scales and almost none from a broad range of global climate models (GCMs). The following study presents global fire datasets and environmental variables used to build spatial statistical baseline models of fire probability and examine the environmental controls on fire activity. As the UN Sendai Framework requires an update of hazard databases and an integration additional manmade hazards in the calculation of risks, this global fire study examines the magnitude and direction of change over two projection periods, 2010-2039 and 2070-2099. From the GCM ensemble results, the study identified areas of consensus for increases or decreases in fires. This type of information may inform policies and strategies of fire-prone nations to better utilize baseline and projection geo-information for enhancing disaster preparedness for what the Sendai Framework is calling an effective response, and to "Build Back Better" in recovery, rehabilitation and reconstruction. Certain biomes are sensitive to constraints on biomass productivity while others to atmospheric conditions promoting combustion. Substantial and rapid shifts are projected for future fire activity across vast portions of the globe. In the near term, the most consistent increases in fire activity occur in biomes with already somewhat warm climates; decreases are less pronounced and concentrated primarily in a few tropical and subtropical biomes. However, models do not agree on the direction of near-term changes across more than 50% of terrestrial lands. Although these models demonstrated that long-term environmental norms captured chronic fire probability patterns, future work is needed to assess how annual variation in climate variables could add more explanatory power. This study provides an examination of global disruptions to fire activity using a

    2015-03-01

    In this article, we pointed out that understanding the physiology of differential climate change effects on organisms is one of the many urgent challenges faced in ecology and evolutionary biology. We explore how physiological ecology can contribute to a holistic view of climate change impacts on organisms and ecosystems and their evolutionary responses. We suggest that theoretical and experimental efforts not only need to improve our understanding of thermal limits to organisms, but also to consider multiple stressors both on land and in the oceans. As an example, we discuss recent efforts to understand the effects of various global change drivers on aquatic ectotherms in the field that led to the development of the concept of oxygen and capacity limited thermal tolerance (OCLTT) as a framework integrating various drivers and linking organisational levels from ecosystem to organism, tissue, cell, and molecules. We suggest seven core objectives of a comprehensive research program comprising the interplay among physiological, ecological, and evolutionary approaches for both aquatic and terrestrial organisms. While studies of individual aspects are already underway in many laboratories worldwide, integration of these findings into conceptual frameworks is needed not only within one organism group such as animals but also across organism domains such as Archaea, Bacteria, and Eukarya. Indeed, development of unifying concepts is relevant for interpreting existing and future findings in a coherent way and for projecting the future ecological and evolutionary effects of climate change on functional biodiversity. We also suggest that OCLTT may in the end and from an evolutionary point of view, be able to explain the limited thermal tolerance of metazoans when compared to other organisms. PMID:25798220

    A climate change MOOC is a way to reach a global audience of many thousands of students. What was it like to teach climate change to an invisible class over the Internet, and how well did it work? The need to educate many people about climate change seems obvious. Climate change is one of the most important existential issues of our time. Sound science can inform wise policy, and coping successfully with climate change is surely an urgent global challenge that requires scientific input and a scientifically informed public. Today many scientists have opportunities to communicate what science has learned about climate and climate change. Yet being a scientific expert on these subjects does not necessarily mean having the skills to communicate effectively to a broad audience. Like learning to ski or to drive a car skillfully, learning to communicate climate science well takes time and effort. The MOOC format has its own special challenges. Effective communication should always resemble a conversation rather than a monologue, but a conversation can be difficult when the teacher will never see or hear from the great majority of students in the class. In addition, a well-funded and effective professional disinformation campaign has been successful in sowing widespread confusion about climate change. As a result, many people mistakenly think climate change science is unreliable or is controversial within the expert community. One can expect that some of the students taking the MOOC will have been influenced by this sort of erroneous information. Thus, one appealing topic to include in a MOOC on climate change is to give useful guidelines for recognizing and rejecting junk science and disinformation. This talk will describe one climate scientist's first-person participation in teaching a climate change MOOC.

  12. Climate Change and Nuclear Power 2014

    International Nuclear Information System (INIS)

    Climate change is the foremost global environmental issue today. Nuclear power is one of the low carbon technologies that can contribute to reducing greenhouse gas emissions while delivering energy in the increasingly large quantities needed for growing populations and socioeconomic development. Nuclear power plants produce virtually no greenhouse gas emissions or air pollutants during their operation and only very low emissions over their entire life cycle. Nuclear power fosters energy supply security and industrial development by providing electricity reliably at stable and foreseeable prices. The accident at the Fukushima Daiichi nuclear power plant in March 2011 caused deep public anxiety and raised fundamental questions about the future of nuclear energy throughout the world. It was a wake-up call for everyone involved in nuclear power — a reminder that safety can never be taken for granted. Yet, more than three years after the accident, it is clear that nuclear energy will remain an important option for many countries. Its advantages in terms of climate change mitigation are an important reason why many countries intend to introduce nuclear power in the coming decades, or to expand existing programmes. All countries have the right to use nuclear technology for peaceful purposes, as well as the responsibility to do so safely and securely. The IAEA provides assistance and information to countries that wish to introduce nuclear power. It also provides information for broader audiences engaged in energy, environmental and economic policy making. This report provides a comprehensive review of the potential role of nuclear power in mitigating global climate change and its contribution to other development and environmental challenges. The report also examines broader issues relevant to the climate change–nuclear energy nexus, such as costs, investments, financing, safety, waste management and non-proliferation.

    International Nuclear Information System (INIS)

    This guidebook contains information about the risks associated with climate change. It explains how existing social, economic and environmental vulnerability can magnify the risks associated with climate change and it describes actions that can be undertaken to prepare for climate change. Key terms and concepts are defined for those unfamiliar with climate change terminology. Chapter 2 outlines what small islands might be able to expect from climate change. It outlines why small islands are vulnerable to climate change, introducing the risks that climate changes pose and the hazards that they might expect. Methods of assessing vulnerability and climate impacts are presented in Chapter 3 and the process of managing the consequences of climate change through the development of an adaptation strategy is introduced. Chapter 4 outlines how you might go about starting the adaptation process, how to make risk management plans and how to link these with other planning processes. Chapter 5 guides you through a process of implementing an adaptation strategy outlining a number of important components including legislation and enforcement, and how to finance adaptation. The importance of continuing the adaptation process is also explained. Chapter 6 includes a glossary containing definitions of the key words and scientific or unusual terms used throughout this guidebook. It also contains information about and links to further sources of information such as useful organisations and publications as well as a list of references to specific documents referenced in the text

    2003-10-01

    Water is going to be one of the key, if not the most critical, environmental issues in the twenty-first century because of the escalation in socio-economic pressures on the environment in general. Any future climate change or climate variability will only accentuate such pressures. This volume initially follows the perspective of the Intergovernmental Panel on Climate Change (IPCC) to infer possible changes in hydrological regimes and water quality based on the outputs from various scenarios of General Circulation Models (GCMs). In subsequent chapters, the possible effects of climate change on the hydrology of each of the continents is examined. The book concludes with an overview of hydrological models for use in the evaluation of the impacts of climate change. It will provide a valuable guide for environmental planners and policy-makers, and will also be of use to all students and researchers interested in the possible effects of climate change.

    Copernicus is the European Commission's flagship Earth observation programme that delivers freely accessible operational data and information services. ECMWF has been entrusted to operate two key parts of the Copernicus programme, which will bring a consistent standard to the measurement, forecasting and prediction of atmospheric conditions and climate change: • The Copernicus Atmosphere Monitoring Service, CAMS, provides daily forecasts detailing the makeup composition of the atmosphere from the ground up to the stratosphere. • The Copernicus Climate Change Service (C3S) (in development) will routinely monitor and analyse more than 20 essential climate variables to build a global picture of our climate, from the past to the future, as well as developing customisable climate indicators for relevant economic sectors, such as energy, water management, agriculture, insurance, health…. C3S has now taken off and a number of proof-of-concept sectoral climate services have been initiated. This paper will focus on the description and expected outcome of these proof-of-concept activities as well as the definition of a roadmap towards a fully operational European Climate Change Service.

    In summary, climate change of the magnitude that is now being talked about promises to invoke major changes in the nature of the world we live in. From an agricultural and food production perspective new challenges are already emerging and many countries, regional organizations and international agencies are ill-prepared to deal with them. From the perspective of the forced emergence of new diseases. There may also be complex struggles for scarce resources including land, water, food and housing. To what extent these will translate into social and political instability is not clear, but the potential for instability within and between countries should not be under-estimated; nor should the scarcity of selected commodities. Understanding these complex dynamics and planning for them in timely and comprehensive ways is essential. Preparedness by governments, the international community and the private sector, will help accommodate some of the changes that are already taking place and many others which are still to materialize.

  20. Climate change and hydroelectric production

    International Nuclear Information System (INIS)

    Manitoba Hydro is planning for the possibility of climate change, which has the potential to adversely effect its hydroelectric generating potential. Theoretical and physical evidence for a global warming are reviewed, and it is shown that some of Manitoba Hydro's own measurements support a warming hypothesis. The most significant effect on the hydraulic generating system would be associated with diminished river flows. Winter hydraulic generation capability would be reduced if the magnitude of the change were sufficient to cause several freeze-ups and break-ups within a given season. Incidence of transmission line icing would probably increase, permafrost recession may undermine tower foundations, and conductor resistance may increase to increase energy loss. Ice crossings and winter roads would be adversely affected, and a restriction on fossil fuel consumption could limit thermal generation and increase demand for hydroelectric or nuclear energy. Manitoba Hydro is examining a number of no-cost or low-cost options to accomodate potential climate change, using probable maximum precipitation hydrologic technology, research into conductor galloping, line icing detection, and hydrological investigations

    Providing opportunities for individuals to contribute to a better understanding of climate change is the hallmark of Project BudBurst (www.budburst.org). This highly successful, national citizen science program, currently finishing its third year, is bringing climate change education outreach to thousands of individuals. Project BudBurst is a national citizen science initiative designed to engage the public in observations of phenological (life cycle) events that raise awareness of climate change, and create a cadre of informed citizen scientists. Citizen science programs such as Project BudBurst provide the opportunity for students and interested laypersons to actively participate in scientific research. Such programs are important not only from an educational perspective, but because they also enable scientists to broaden the geographic and temporal scale of their observations. The goals of Project BudBurst are to 1) increase awareness of phenology as an area of scientific study; 2) Increase awareness of the impacts of changing climates on plants; and 3) increase science literacy by engaging participants in the scientific process. In anticipation of the 2010 campaign, Project BudBurst has developed and released innovative and exciting projects with a special focus in the field of phenology and climate change. The collaborations between Project BudBurst and other organizations are producing unique campaigns for engaging the public in environmental research. The special project foci include on-the-spot and in-the-field data reporting via mobile phones, an emphasis on urban tree phenology data, as well as monitoring of native gardens across the US National Wildlife Refuge System. This presentation will provide an overview of Project Budburst and the new special projects, and share results from 2007-2009. Project BudBurst is managed by the University Corporation for Atmospheric Research, the Chicago Botanic Garden, and the University of Montana.

  2. Use of the computational-informational web-GIS system for the development of climatology students' skills in modeling and understanding climate change

    2015-04-01

    The current situation with the training of specialists in environmental sciences is complicated by the fact that the very scientific field is experiencing a period of rapid development. Global change has caused the development of measurement techniques and modeling of environmental characteristics, accompanied by the expansion of the conceptual and mathematical apparatus. Understanding and forecasting processes in the Earth system requires extensive use of mathematical modeling and advanced computing technologies. As a rule, available training programs in the environmental sciences disciplines do not have time to adapt to such rapid changes in the domain content. As a result, graduates of faculties do not understand processes and mechanisms of the global change, have only superficial knowledge of mathematical modeling of processes in the environment. They do not have the required skills in numerical modeling, data processing and analysis of observations and computation outputs and are not prepared to work with the meteorological data. For adequate training of future specialists in environmental sciences we propose the following approach, which reflects the new "research" paradigm in education. We believe that the training of such specialists should be done not in an artificial learning environment, but based on actual operating information-computational systems used in environment studies, in the so-called virtual research environment via development of virtual research and learning laboratories. In the report the results of the use of computational-informational web-GIS system "Climate" (http://climate.scert.ru/) as a prototype of such laboratory are discussed. The approach is realized at Tomsk State University to prepare bachelors in meteorology. Student survey shows that their knowledge has become deeper and more systemic after undergoing training in virtual learning laboratory.

    For the last 35 years, the average temperature of the planet has been steadily increasing- Are the greenhouse gases emitted by human beings the cause? What will the consequences be? What can we do? The fourth report of the intergovernmental Panel on Climate change tries to answer these questions. There are clear signs of thawing that primary affect Greenland and the Antarctic, but there are still many doubts what the consequences will be throughout the century. In any case, it seems obvious that, if greenhouse gas emissions are not substantially reduced very soon, the rising temperature trend and its associated consequences will persist beyond the 21st century.

    The purpose of this paper is to explore some of the key methodological issues that arise from an analysis of regional climate change mitigation options. The rationale for any analysis of regional mitigation activities, emphasising both the theoretical attractiveness and the existing political encouragement and the methodology that has been developed are reviewed. The differences arising from the fact that mitigation analyses have been taken from the level of the national - where the majority of the work has been completed to date - to the level of the international - that is, the `regional` - will be especially highlighted.

    1992-01-01

    One of the main problems caused by climate change is the greenhouse effect. Human activities emit so-called greenhouse gases into the atmosphere, such as carbon dioxide which is produced through fossil fuel burning. These gases absorb the earth‘s radiation, forcing the earth‘s temperature, like that of in greenhouse, to rise. Global warming would lead to a rise in the global mean sea-level due to thermal expansion of the waters, and glaciers will melt at a fast rate, as will the Greenland ice...

  7. Putting Climate Change Adaptation in the Development Mainstream. Policy Brief

    International Nuclear Information System (INIS)

    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

  8. Climate Change and Nuclear Power 2015

    International Nuclear Information System (INIS)

    Climate change is one of the most important environmental challenges facing the world today. Nuclear power can make a significant contribution to reducing greenhouse gas emissions while delivering energy in the increasingly large quantities needed for growing populations and socioeconomic development. Nuclear power plants produce virtually no greenhouse gas emissions or air pollutants during their operation and only very low emissions over their entire life cycle. Nuclear power fosters energy supply security and industrial development by providing electricity reliably at stable and foreseeable prices. The accident at the Fukushima Daiichi nuclear power plant in March 2011 caused deep public anxiety and raised fundamental questions about the future of nuclear energy throughout the world. Yet, more than four years after the accident, it is clear that nuclear energy will remain an important option for many countries. Its advantages in terms of climate change mitigation are an important reason why many countries intend to introduce nuclear power in the coming decades, or to expand existing programmes. All countries have the right to use nuclear technology for peaceful purposes, as well as the responsibility to do so safely and securely. The IAEA provides assistance and information to countries that wish to introduce nuclear power. It also provides information for broader audiences engaged in energy, environmental and economic policy making. This report provides a comprehensive review of the potential role of nuclear power in mitigating global climate change and its contribution to other economic, energy and environmental challenges. The report also examines broader issues relevant to the climate change–nuclear energy nexus, such as costs, investments, financing, safety, waste management and non-proliferation. Recent developments in electricity generation and distribution technologies and their impacts on nuclear power are also presented. This edition has been

  14. Implications of Climate Change for Ghana’s Economy

    Directory of Open Access Journals (Sweden)

    Channing Arndt

    2015-06-01

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

  16. Regional Collaborations to Combat Climate Change: The Climate Science Centers as Strategies for Climate Adaptation

    Science.gov (United States)

    Morelli, T. L.; Palmer, R. N.

    2014-12-01

    The Department of Interior Northeast Climate Science Center (NE CSC) is part of a federal network of eight Climate Science Centers created to provide scientific information, tools, and techniques that managers and other parties interested in land, water, wildlife and cultural resources can use to anticipate, monitor, and adapt to climate change. The consortium approach taken by the CSCs allows the academic side of the Centers to gather expertise across departments, disciplines, and even institutions. This interdisciplinary approach is needed for successfully meeting regional needs for climate impact assessment, adaptive management, education, and stakeholder outreach. Partnership with the federal government facilitates interactions with the key on-the-ground stakeholders who are able to operationalize the results and conclusions of that research, monitor the progress of management actions, and provide feedback to refine future methodology and decisions as new information on climate impacts is discovered. For example, NE CSC researchers are analyzing the effect of climate change on the timing and volume of seasonal and annual streamflows and the concomitant effects on ecological and cultural resources; developing techniques to monitor tree range dynamics as affected by natural disturbances which can enable adaptation of projected climate impacts; studying the effects of changes in the frequency and magnitude of drought and stream temperature on brook trout habitats, spatial distribution and population persistence; and conducting assessments of northeastern regional climate projections and high-resolution downscaling. Project methods are being developed in collaboration with stakeholders and results are being shared broadly with federal, state, and other partners to implement and refine effective and adaptive management actions.

    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...

    Commitment of the Canadian Mining Association (MAC), on behalf of its member companies, to play a global leadership role in eco-efficiency and environmental stewardship and participate fully in Canada's efforts to reduce emissions that contribute to climate change, are outlined. The principles underlying the MAC's commitment include: prudent action to reduce GHG emissions; the greatest possible efficiency in using energy; use of best practices and technologies; support for the development of balanced climate change policies; cooperation with all stakeholders in achieving the maximum feasible reduction in GHG emissions; support for research and analysis of the social, economic and environmental implications of GHG reduction strategies; and active support for a balanced and effective public outreach and education program. A brief review of how the mining sector has already made giant strides in cutting energy consumption and in reducing carbon dioxide equivalent emissions per unit of output during the past decade is supplemented by summaries of GHG reduction success stories from member companies such as Cominco, Teck Corporation, Falconbridge and Syncrude Canada Limited

  1. Nuclear power and climate change

    International Nuclear Information System (INIS)

    In the Kyoto Protocol, agreed upon by the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) in December 1997, Annex I countries committed to reduce their greenhouse gas (GHG) emissions. Also, the Protocol states that Annex I countries shall undertake promotion, research, development and increased use of new and renewable forms of energy, of carbon dioxide sequestration technologies and of advanced and innovative environmentally sound technologies. One important option that could be covered by the last phrase, and is not specifically mentioned, is nuclear energy which is essentially carbon-free. Nuclear Energy Agency (NEA) has investigated the role that nuclear power could play in alleviating the risk of global climate change. The main objective of the study is to provide a quantitative basis for assessing the consequences for the nuclear sector and for the reduction of GHG emissions of alternative nuclear development paths. The analysis covers the economic, financial, industrial and potential environmental effects of three alternative nuclear power development paths ('nuclear variants'). (K.A.)

  2. Market Forces Fight Climate Change?

    International Nuclear Information System (INIS)

    The Kyoto Protocol set industrialised nations' targets for cutting emissions of greenhouse gases, and promoted the so called flexible international market mechanisms to support those cuts, i.e. international emissions trading, joint implementation and clean development mechanisms. Greenhouse policy instruments should be environmentally effective, economically rational, equitable in allocation of emission rights, and politically feasible. Because of major uncertainties about both future damages and costs of global warming, it is advisable to start with low-cost and less radical mitigation measures, but to apply them in as many countries as possible. In time, according to the new findings, those measures could be replaced by more radical and more expensive ones (the so-called 'broad, then deep' strategy). Domestic climate change mitigation measures could be implemented only with an effective international agreement in place. One of the domestic measures could be CO2 emission charge, since it would increase the costs of fossil-fuelled plants and make them less competitive relative to other supply options, particularly to the zero-carbon nuclear option. The largest barriers to progress in dealing with climate change are domestic political obstacles and international institutional challenges. (author)

  3. A dissenting view on global climate change

    International Nuclear Information System (INIS)

    Global warming alarmists are vastly overstating the risks of climate change, often to further other agendas. The science of global warming simply does not support their claims of impending doom - as policy makers would be wise to note. There is scientific consensus on the existence of a benign natural greenhouse effect that keeps the Earth habitable by raising its average surface temperature by about 33 degrees C. Global warming alarmists, however, have falsely claimed that this consensus also extends to the belief that human activity is significantly enhancing this effect. This is simply untrue. Based on a wealth of new information, there is now strong and rapidly growing scientific dissent on the inevitability of catastrophic and even mildly detrimental anthropogenic climate change. This casts serious doubts on the need for binding international agreements to curtail emissions of greenhouse gases from fossil fuel combustion, or to limit conversion of tropical forests to agricultural uses in areas where increased food supply is a critical issue

These sheets concern the different fields of application of the plan: cross-cutting actions, health, water resources, biodiversity, natural hazards, agriculture, forest, fishery and aquaculture, energy and industry, transport infrastructures and systems, urban planning and built environment, tourism, information, education and training, research, finance and insurance, coasts, mountains, European and international actions, governance

  5. Multinationals' Political Activities on Climate Change

    International Nuclear Information System (INIS)

    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

    In recent years, amid growing concerns that changing climate is affecting species distributions and ecosystems, predicting responses to rapid environmental change has become a major goal. In this issue, Franks and colleagues take a first step towards this objective (Franks et al. 2016). They examine genomewide signatures of selection in populations of Brassica rapa after a severe multiyear drought. Together with other authors, Franks had previously shown that flowering time was reduced after this particular drought and that the reduction was genetically encoded. Now, the authors have sequenced previously stored samples to compare allele frequencies before and after the drought and identify the loci with the most extreme shifts in frequencies. The loci they identify largely differ between populations, suggesting that different genetic variants may be responsible for reduction in flowering time in the two populations. PMID:27463237

    Climate change can reasonably be described as a "wicked problem" meaning that it is complex, difficult and multi-faceted, although critical to equitable development and the sustainability of human civilization. But while the Wikipedia definition says such problems are "impossible" to solve, not even to try will lead to certain failure. "Earth: The Operators' Manual" (ETOM) was an NSF-funded informal science education project with 3 hour-long TV programs appearing on PBS in 2011 and 2012, along with live presentations by series host, Penn State's Richard Alley, and others at 5 major science centers. Uniquely among climate change programming, ETOM gave equal time to identifying solutions along with climate science, and made all its materials freely available via YouTube. Formal and informal science educators can register to download HD videos for classroom and outreach use, and signups have ranged from middle schools to 4-year colleges. Building on the success of the series and Alley's companion tradebook of the same name, Penn State working with Coursera invited Alley to develop a MOOC entitled "Energy, The Environment and Our Future" that similarly combined the essential science along with clean energy solutions. The course reached more than 30,000 students in the first semester of 2014. More recently the ETOM team has partnered with the National Council for Science and the Environment (NCSE) to develop "READ for the EARTH," an NSF EAGER project, offering campuses the opportunity to adopt Alley's book, the ETOM videos (including "How To Talk To An Ostrich"), NCSE's www.CAMELclimatechange.org web site and other resources for both formal and informal uses.

    Once upon a time climate change was a strictly environment and development issue. Today it has become a matter of national and international security. Efforts to link climate change with violent conflict may not be based on solid evidence, but they have certainly captured the attention of governments. They have played a vital role in raising the much-needed awareness of climate change as an issue that deserves global action. But at what cost? Focusing on climate change as a security threat alone risks devolving humanitarian responsibilities to the military, ignoring key challenges and losing sight of those climate-vulnerable communities that stand most in need of protection.

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

    International Nuclear Information System (INIS)

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

    Parliamentarians can play a key role in building climate resilience by bringing constituents' concerns into national forums, scrutinising how governments are responding to domestic and global climate change issues, and ensuring policy continuity. In the Southern African Customs Union, members of parliament often struggle to fulfill this role, hampered by limited understanding of the issues, fragmented policy and legal frameworks and competing priorities. Boosting parliamentarians' capacity to engage effectively with climate change in Southern Africa requires them to strengthen their research capabilities, diversify their sources of information and build cross-party groups on climate change.

Such analyses are typically performed at the macro scales (e.g., regional, global) where the climate model output could support (e.g., Hirabayashi et al., 2013, Arnell and Gosling, 2014). To understand the potential benefits of infrastructure upgrading as part of climate adaptation strategies, it is also informative to understand the potential impact of different flood protection standards (in terms of return periods) on global river flooding under climate change. In this study, we use a baseline period (forced by observed hydroclimate conditions) and CMIP5 model output (historic and future periods) to drive a global river routing model called CaMa-Flood (Yamazaki et al., 2011) and simulate the river water depth at a spatial resolution of 15 min x 15 min. From the simulated results of baseline period, we use the annual maxima river water depth to fit the Gumbel distribution and prepare the return period-flood risk relationship (involving population and GDP). From the simulated results of CMIP5 model, we also used the annual maxima river water depth to obtain the Gumbel distribution and then estimate the exceedance probability (historic and future periods). We apply the return period-flood risk relationship (above) to the exceedance probability and evaluate the potential risk of river flooding and changes in the benefits of flood protection standard (e.g., 100-year flood of the baseline period) from the past into the future (represented by the representative concentration pathways). In this presentation, we show our preliminary results. References: Arnell, N.W, Gosling, S., N., 2014. The impact of climate change on river flood risk at the global scale.
