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.

Summarizes the science of climate change and impacts on the United States, for the public and policymakers.

The warming of the Earth has been the subject of intense debate and concern for many scientists, policy-makers, and citizens for at least the past decade. Climate Change Science: An Analysis of Some Key Questions, a new report by a committee of the National Research Council, characterizes the global warming trend over the last 100 years, and examines what may be in store for the 21st century and the extent to which warming may be attributable to human activity.

In December 2015, 196 parties to the United Nations Framework Convention on Climate Change (UNFCCC) adopted the Paris Agreement, seen as a decisive landmark for global action to stop human- induced climate change. The Paris Agreement will replace the 1997 Kyoto Protocol which expires in 2020, and it creates legally binding obligations on the parties, based on their own bottom-up voluntary commitments to implement Nationally Determined Contributions (NDCs). The codification of the climate change regime has advanced well, but the implementation of it remains uncertain. This book focuses on the implementation prospects of the Agreement, which is a challenge for all and will require a fully comprehensive burden- sharing framework. Parties need to meet their own NDCs, but also to finance and transfer technology to others who do not have enough. How equity- based and facilitative the process will be, is of crucial importance. The volume examines a broad range of issues including the lessons that can be learnt from the implementation of previous environmental legal regimes, climate policies at national and sub-national levels and whether the implementation mechanisms in the Paris Agreement are likely to be sufficient. Written by leading experts and practitioners, the book diagnoses the gaps and lays the ground for future exploration of implementation options. This collection will be of interest to policy-makers, academics, practitioners, students and researchers focusing on climate change governance.

Climate change impacts upon the world's poorest most heavily. It is therefore essential that international development initiatives focus on improving the ability of developing countries to adapt to the effects of climate change. This book, a product of research by the JICA-RI (Research Institute of the Japan International Cooperation Agency), examines climate change adaptation from the perspective of development cooperation in order to provide useful lessons for those engaged in research, policy and practice in this vital area. In this book the editors have brought together a wide range of case studies from across Africa and Asia, covering urban and rural areas and different sectors including water, agriculture and disaster management, in order to examine the following: o high-resolution climate change projection in Asia and how this can be used in planning appropriate adaptation responses o in-depth case studies of climate change projections, social, economic and environmental impact and vulnerability assessment and adaptation in rural Thailand and urban Philippines o cases across Africa for which climate data is less readily available and alternative approaches need to be adopted o the current situation amongst international donors o emerging issues caused by climate change In the introductory section, the editors draw together the full implications from the case studies to discuss how international communities can support adaptation in developing countries and to give an assessment of bilateral projects. They reflect on the lessons learned and offer recommendations for future research and international development cooperation.

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.
