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 148-page Highlights book presents the major findings and selected highlights from Climate Change Impacts in the United States: The Third National Climate Assessment. The Highlights report is organized around the National Climate Assessment’s 12 Report Findings, which take an overarching view of the entire report and its 30 chapters.
The Synthesis Report synthesizes the main findings of the IPCC's Fifth Assessment Report, based on contributions from Working Group I (The Physical Science Basis), Working Group II (Impacts, Adaptation and Vulnerability), and Working Group III (Mitigation of Climate Change), plus two additional IPCC reports.
This 20-page booklet provides a high-level compendium of Climate Change Impacts in the United States: The Third National Climate Assessment. The Overview covers the most important impacts at the national level but does not attempt to provide a comprehensive summary of the entire assessment.
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.
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.
