America S Climate Choices

Climate change is occurring. It is very likely caused by the emission of greenhouse gases from human activities, and poses significant risks for a range of human and natural systems. And these emissions continue to increase, which will result in further change and greater risks. America's Climate Choices makes the case that the environmental, economic, and humanitarian risks posed by climate change indicate a pressing need for substantial action now to limit the magnitude of climate change and to prepare for adapting to its impacts. Although there is some uncertainty about future risk, acting now will reduce the risks posed by climate change and the pressure to make larger, more rapid, and potentially more expensive reductions later. Most actions taken to reduce vulnerability to climate change impacts are common sense investments that will offer protection against natural climate variations and extreme events. In addition, crucial investment decisions made now about equipment and infrastructure can "lock in" commitments to greenhouse gas emissions for decades to come. Finally, while it may be possible to scale back or reverse many responses to climate change, it is difficult or impossible to "undo" climate change, once manifested. Current efforts of local, state, and private-sector actors are important, but not likely to yield progress comparable to what could be achieved with the addition of strong federal policies that establish coherent national goals and incentives, and that promote strong U.S. engagement in international-level response efforts. The inherent complexities and uncertainties of climate change are best met by applying an iterative risk management framework and making efforts to significantly reduce greenhouse gas emissions; prepare for adapting to impacts; invest in scientific research, technology development, and information systems; and facilitate engagement between scientific and technical experts and the many types of stakeholders making America's climate choices.

Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.

Drought, floods, hurricanes, forest fires, ice storms, blackouts, dwindling fish stocks...what Canadian has not experienced one of these or more, or heard about the “greenhouse” effect, and not wondered what is happening to our climate? Yet most of us have a poor understanding of this extremely important issue, and need better, reliable scientific information. Hard Choices: Climate Change in Canada delivers some hard facts to help us make some of those hard choices. This new collection of essays by leading Canadian scientists, engineers, social scientists, and humanists offers an overview and assessment of climate change and its impacts on Canada from physical, social, technological, economic, political, and ethical / religious perspectives. Interpreting and summarizing the large and complex literatures from each of these disciplines, the book offers a multidisciplinary approach to the challenges we face in Canada. Special attention is given to Canada’s response to the Kyoto Protocol, as well as an assessment of the overall adequacy of Kyoto as a response to the global challenge of climate change. Hard Choices fills a gap in available books which provide readers with reliable information on climate change and its impacts that are specific to Canada. While written for the general reader, it is also well suited for use as an undergraduate text in environmental studies courses.

Global climate change is one of America's most significant long-term policy challenges. Human activity-especially the use of fossil fuels, industrial processes, livestock production, waste disposal, and land use change-is affecting global average temperatures, snow and ice cover, sea-level, ocean acidity, growing seasons and precipitation patterns, ecosystems, and human health. Climate-related decisions are being carried out by almost every agency of the federal government, as well as many state and local government leaders and agencies, businesses and individual citizens. Decision makers must contend with the availability and quality of information, the efficacy of proposed solutions, the unanticipated consequences resulting from decisions, the challenge of implementing chosen actions, and must consider how to sustain the action over time and respond to new information. Informing an Effective Response to Climate Change, a volume in the America's Climate Choices series, describes and assesses different activities, products, strategies, and tools for informing decision makers about climate change and helping them plan and execute effective, integrated responses. It discusses who is making decisions (on the local, state, and national levels), who should be providing information to make decisions, and how that information should be provided. It covers all levels of decision making, including international, state, and individual decision making. While most existing research has focused on the physical aspect of climate change, Informing an Effective Response to Climate Change employs theory and case study to describe the efforts undertaken so far, and to guide the development of future decision-making resources. Informing an Effective Response to Climate Change offers much-needed guidance to those creating public policy and assists in implementing that policy. The information presented in this book will be invaluable to the research community, especially social scientists studying climate change; practitioners of decision-making assistance, including advocacy organizations, non-profits, and government agencies; and college-level teachers and students.

This book showcases experiences from research, field projects and best practice in climate change adaptation in countries in the Latin American region, focusing on managing vulnerability and fostering resilience. It includes a selection of papers presented at a specialist symposium on climate change adaptation held in Rio de Janeiro, Brazil in November 2016.Consistent with the need for more cross-sectoral interaction among the various stakeholders working in the field of climate change adaptation in Latin America, the book documents and disseminates the wealth of experiences in the region. It is divided into two main parts: Part 1 addresses the current and future impacts of climate change on fauna, flora and landscapes, while Part 2 is concerned with the socio-economic aspects of climate change adaptation, analyzing some of the main problems prevailing in this vulnerable region and examining ways to address them.
