Severe droughts, damaging floods and mass migration: Climate change is becoming a focal point for security and conflict research and a challenge for the world’s governance structures. But how severe are the security risks and conflict potentials of climate change? Could global warming trigger a sequence of events leading to economic decline, social unrest and political instability? What are the causal relationships between resource scarcity and violent conflict? This book brings together international experts to explore these questions using in-depth case studies from around the world. Furthermore, the authors discuss strategies, institutions and cooperative approaches to stabilize the climate-society interaction.

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.

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.

Violent conflicts today are complex and increasingly protracted, involving more nonstate groups and regional and international actors. It is estimated that by 2030—the horizon set by the international community for achieving the Sustainable Development Goals—more than half of the world’s poor will be living in countries affected by high levels of violence. Information and communication technology, population movements, and climate change are also creating shared risks that must be managed at both national and international levels. Pathways for Peace is a joint United Nations†“World Bank Group study that originates from the conviction that the international community’s attention must urgently be refocused on prevention. A scaled-up system for preventive action would save between US$5 billion and US$70 billion per year, which could be reinvested in reducing poverty and improving the well-being of populations. The study aims to improve the way in which domestic development processes interact with security, diplomacy, mediation, and other efforts to prevent conflicts from becoming violent. It stresses the importance of grievances related to exclusion—from access to power, natural resources, security and justice, for example—that are at the root of many violent conflicts today. Based on a review of cases in which prevention has been successful, the study makes recommendations for countries facing emerging risks of violent conflict as well as for the international community. Development policies and programs must be a core part of preventive efforts; when risks are high or building up, inclusive solutions through dialogue, adapted macroeconomic policies, institutional reform, and redistributive policies are required. Inclusion is key, and preventive action needs to adopt a more people-centered approach that includes mainstreaming citizen engagement. Enhancing the participation of women and youth in decision making is fundamental to sustaining peace, as well as long-term policies to address the aspirations of women and young people.

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.

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.

Jon Barnett takes on the military-industrial interests of those in the establishment to reveal how ordinary human beings must have a safe environment in which security is subordinate to care of the planet and its delicate ecosystems.
