The Reports Library features scientific assessments, annual reports, strategic research plans, and other resources produced by USGCRP and the collaborative efforts of our member agencies. Select reports by other authoritative scientific bodies with whom we work, such as the Intergovernmental Panel on Climate Change (IPCC) and the National Research Council (NRC), are also accessible here. Most reports are available for download (open and click View); some can be ordered in print free of charge (open and click Add to Cart).
Please note that we are currently experiencing shipping delays of at least two weeks. Thank you for your patience.
The Working Group I contribution to the IPCC’s Fifth Assessment Report (WGI AR5) provides a comprehensive assessment of the physical science basis of climate change.
The two-volume report from the IPCC's Working Group II 1) assesses risks and opportunities for societies, economies, and ecosystems around the world, and 2) considers unique features of major world regions.
The Working Group III contribution to the IPCC’s Fifth Assessment Report provides a comprehensive assessment of all relevant options for mitigating climate change through limiting or preventing greenhouse gas emissions, as well as activities that remove them from the atmosphere.
Includes the full report, technical summary, and summary for policymakers.
This Special Report of the IPCC Working Groups I and II explores the social as well as physical dimensions of weather- and climate-related disasters, considering opportunities for managing risks at local to international scales.
The 2014 U.S. Climate Action Report fulfills a commitment under the United Nations Framework Convention on Climate Change (UNFCCC) to publish every four years a National Communication that provides a comprehensive report on actions taken to combat climate change and thereby meet the objectives and provisions of the UNFCCC.
This report is the Second National Climate Assessment. It summarizes the science of climate change and the impacts of climate change on the United States, now and in the future.
Adapting to the Impacts of Climate Change calls for a national adaptation strategy that provides needed technical and scientific resources, incentives to begin adaptation planning, guidance across jurisdictions, shared lessons learned, and support of scientific research to expand knowledge of impacts and adaptation.
America's Climate Choices makes the case that the environmental, economic, and humanitarian risks posed by climate change indicate a pressing need for substantial action now to limit the magnitude of climate change and to prepare for adapting to its impacts.
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.
