Climate change can reasonably be expected to increase the frequency and intensity of a variety of potentially disruptive environmental events-slowly at first, but then more quickly. It is prudent to expect to be surprised by the way in which these events may cascade, or have far-reaching effects. During the coming decade, certain climate-related events will produce consequences that exceed the capacity of the affected societies or global systems to manage; these may have global security implications. Although focused on events outside the United States, Climate and Social Stress: Implications for Security Analysis recommends a range of research and policy actions to create a whole-of-government approach to increasing understanding of complex and contingent connections between climate and security, and to inform choices about adapting to and reducing vulnerability to climate change.

In this unique and innovative contribution to environmental security, an international team of scholars explore and estimate the intermediate-term security risks that climate change may pose for the United States, its allies and partners, and for regional and global order through the year 2030. In profiles of forty-two key countries and regions, each contributor considers the problems that climate change will pose for existing institutions and practices. By focusing on the conduct of individual states or groups of nations, the results add new precision to our understanding of the way environmental stress may be translated into political, social, economic, and military challenges in the future. Countries and regions covered in the book include China, Vietnam, The Philippines, Indonesia, India, Pakistan, Bangladesh, Central Asia, the European Union, the Persian Gulf, Egypt, Turkey, the Maghreb, West Africa, Southern Africa, the Northern Andes, and Brazil.

Connections between climate change and national security are receiving unprecedented attention from policymakers and analysts. In this report, Joshua W. Busby moves the discussion from broad assessments of the links between climate and security to a plan for action.

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.

How can the United States craft a sustainable national security strategy in a world of shifting threats, sharp resource constraints, and a changing balance of power? This volume brings together research on this question from political science, history, and political economy, aiming to inform both future scholarship and strategic decision-making.

"Presents three scenarios of what the future may hold: expected, severe, and catastrophic and analyzes the security implications of each. Considers what can be learned from early civilizations confronted with natural disaster and asks what the largest emitters of greenhouse gases can do to reduce and manage future risks"--Provided by publisher.

Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.
