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.
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.

Findings, Summary, and Frequently Asked Questions of the U.S. Climate Change Science Program Synthesis and Assessment Repor 2.2: The First State of the Carbon Cycle Report: North American Carbon Budget and Implications for the Global Carbon Cycle.
This report summarizes a workshop that focused on two case studies to provide different perspectives on multiple environmental stressors: 1) drought; 2) atmosphere-ecosphere interactions. Workshop participants identified the development of comprehensive regional frameworks for conducting environmental studies as a key part of understanding multiple environmental stresses.
