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).

This Overview Report presents a summary of the first comprehensive assessment of Arctic Ocean Acidification conducted by the Arctic Monitoring and Assessment Programme (AMAP).
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.
This report summarizes the Working Group II contribution to the IPCC's Fifth Assessment Report on climate change. It considers the vulnerability and exposure of human and natural systems, the observed impacts and future risks of climate change, and the potential for and limits to adaptation.
This publication includes the Summary for Policymakers, Technical Summary, Frequently Asked Questions, and Cross-Chapter Boxes for the Working Group II contribution to the IPCC Fifth Assessment Report.
Ocean acidification is occurring at a rapid and accelerating pace, and the Arctic Ocean is on the frontline of this global change. AMAP’s 2013 assessment of Arctic Ocean acidification provides the first Arctic-wide perspective on today’s progressively increasing seawater acidity.
The 2009 Arctic Marine Shipping Assessment (AMSA) called for the Arctic States to identify areas of heightened ecological and cultural significance in light of changing climate conditions and increasing multiple marine uses. This report identifies those areas.
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 Working Group I contribution to the IPCC Fifth Assessment Report (WGI AR5) provides a comprehensive assessment of the physical science basis of climate change. Here, the Working Group I report is summarized for both technical and policy audiences.
This report synthesizes the contributions of Working Groups I, II, and III to the IPCC’s Fourth Assessment Report, and also draws on recent IPCC Special Reports. It draws together policy-relevant scientific, technical, and socioeconomic information related to climate change, with the goal of assisting governments and other decision makers in formulating and implementing responses.
This report is the contribution of Working Group I to the IPCC’s Fourth Assessment Report. It provides insights into the effects of human activity on the atmosphere; contains an evaluation of observed climatic changes using the latest measurement techniques; includes a detailed review of climate change observations and modeling for every continent; and features the first probabilistic evaluation of climate model simulations.
