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.
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.
The stresses associated with climate change are expected to be felt keenly as human population grows to a projected 9 billion by the middle of this century, increasing the demand for resources and supporting infrastructure. Therefore, information to assess vulnerabilities to climate change is needed to support policies and investments designed to increase resilience in human and Earth systems. There are currently many observing systems that capture elements of how climate is changing, for example, direct measurements of atmospheric and ocean temperature. Although those measurements are essential for understanding the scale and nature of climate change, they do not necessarily provide information about the impacts of climate change on humans that are especially relevant for political and economic planning and decision making. Monitoring Climate Change Impacts tackles the challenge of developing an illustrative suite of indicators, measurements (and the locations around the globe where the measurements can be applied), and metrics that are important for understanding global climate change and providing insight into environmental sustainability. Eight panels provided input on: cryosphere, land-surface and terrestrial ecosystems, hydrology and water resources, atmosphere, human health and other dimensions, oceans (both physical and biological/chemical), and natural disasters. The book also provides an illustrative set of metrics that are likely to be affected by climate change over the next 20-25 years and, when taken together, can potentially give advance warning of climate-related changes to the human and environment systems.
Ending poverty and stabilizing climate change will be two unprecedented global achievements and two major steps toward sustainable development. But the two objectives cannot be considered in isolation: they need to be jointly tackled through an integrated strategy. This report brings together those two objectives and explores how they can more easily be achieved if considered together. It examines the potential impact of climate change and climate policies on poverty reduction. It also provides guidance on how to create a “win-win†? situation so that climate change policies contribute to poverty reduction and poverty-reduction policies contribute to climate change mitigation and resilience building. The key finding of the report is that climate change represents a significant obstacle to the sustained eradication of poverty, but future impacts on poverty are determined by policy choices: rapid, inclusive, and climate-informed development can prevent most short-term impacts whereas immediate pro-poor, emissions-reduction policies can drastically limit long-term ones.
This book examines the multiple strategies proposed by the international community for addressing global climate change (GCC) from both human and state-security perspectives. It examines what is needed from major states working within the UN framework to engage with the multiple dimensions of a strategy that addresses GCC and its impacts, where such engagement promotes both human and state security. Two broad frameworks for approaching these issues provide the basis of discussion for the individual chapters, which discuss the strategies being undertaken by major state powers (the US, the EU, China, India, Japan, and Russia). The first framework considers the multiple strategies, mitigation, adaptation, and capacity-building required of the international community to address the effects of GCC. The second framework considers the differentiation of GCC policies in terms of security and how the efficacy of these strategies could be impacted by whether priority is given to state security over human security concerns. This book will be of much interest to students of human security, climate change, foreign policy, and International Relations.
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.
Climate change affects virtually every aspect of the U.S. energy system. As climatic effects such as rising seas and extreme weather continue to appear across many geographies, U.S. energy infrastructure is increasingly at risk. The U.S. Gulf Coast--which is home to 44 percent of total U.S. oil refining capacity and several major ports--is highly vulnerable to flooding events and dangerous ocean surges during severe storms and hurricanes. The link between water availability and energy and electricity production creates another layer of risk to U.S. energy security. Climate risk could manifest not only in physical damages, but also in financial market failures. Climate change-related challenges could impede energy firms' access to capital markets or private insurance markets. Already, climate-related risks have created severe financial problems at a handful of U.S. energy firms, forcing them to interrupt their sales of energy to consumers in particular locations. Over time, climatic disruptions to domestic energy supply could entail huge economic losses and potentially require sizable domestic military mobilizations. The United States is ill prepared for this national security challenge, and public debate about emergency preparedness is virtually nonexistent. To explore the challenges of climate risk to the U.S. energy system and national security, the Council on Foreign Relations organized a two-day workshop in New York, on March 18 and 19, 2019. The gathering of fifty participants included current and former state and federal government officials and regulators, entrepreneurs, scientists, investors, financial- and corporate-sector leaders, credit agencies, insurers, nongovernmental organizations, and energy policy experts. During their deliberations, workshop participants explored how climate-related risks to U.S. energy infrastructure, financial markets, and national security could be measured, managed, and mitigated. Impact of Climate Risk on the Energy System summarizes the insights from this workshop and includes contributions from seven expert authors delving into related topics.
