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.

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.

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.

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.

Experts discuss the risks global environmental change poses for the human security, including disaster and disease, violence, and increasing inequity. In recent years, scholars in international relations and other fields have begun to conceive of security more broadly, moving away from a state-centered concept of national security toward the idea of human security, which emphasizes the individual and human well-being. Viewing global environmental change through the lens of human security connects such problems as melting ice caps and carbon emissions to poverty, vulnerability, equity, and conflict. This book examines the complex social, health, and economic consequences of environmental change across the globe. In chapters that are both academically rigorous and policy relevant, the book discusses the connections of global environmental change to urban poverty, natural disasters (with a case study of Hurricane Katrina), violent conflict (with a study of the decade-long Nepalese civil war), population, gender, and development. The book makes clear the inadequacy of traditional understandings of security and shows how global environmental change is raising new, unavoidable questions of human insecurity, conflict, cooperation, and sustainable development.

All Hell Breaking Loose is an eye-opening examination of climate change from the perspective of the U.S. military. The Pentagon, unsentimental and politically conservative, might not seem likely to be worried about climate change—still linked, for many people, with polar bears and coral reefs. Yet of all the major institutions in American society, none take climate change as seriously as the U.S. military. Both as participants in climate-triggered conflicts abroad, and as first responders to hurricanes and other disasters on American soil, the armed services are already confronting the impacts of global warming. The military now regards climate change as one of the top threats to American national security—and is busy developing strategies to cope with it. Drawing on previously obscure reports and government documents, renowned security expert Michael Klare shows that the U.S. military sees the climate threat as imperiling the country on several fronts at once. Droughts and food shortages are stoking conflicts in ethnically divided nations, with “climate refugees” producing worldwide havoc. Pandemics and other humanitarian disasters will increasingly require extensive military involvement. The melting Arctic is creating new seaways to defend. And rising seas threaten American cities and military bases themselves. While others still debate the causes of global warming, the Pentagon is intensely focused on its effects. Its response makes it clear that where it counts, the immense impact of climate change is not in doubt.

Busby explains how climate change can affect security outcomes, including violent conflict and humanitarian emergencies. Through case studies from sub-Saharan Africa, the Middle East, and South Asia, the book develops a novel argument explaining why climate change leads to especially bad security outcomes in some places but not in others.
