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 report, organized under the auspices of USGCRP's Adaptation Science Interagency Working Group, is a snapshot in time (2013-2014) of the status of climate change adaptation in Federal agencies that study and manage land and water resources.
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.
This document describes areas of future growth for the Global Change SysTem for Analysis and Training (START), including strengthening and expanding trans-disciplinary and multi-sectoral expertise in integrated research and assessment; promoting effective communication between communities of research, policy, and practice; and supporting efforts by universities in Africa and Asia-Pacific to inform and engage society in creating more resilient development trajectories.
START, founded in 1992, promotes research-driven capacity building that advances knowledge generation and sharing on global environmental change (GEC) issues, including climate change. This biennial report described START's programs related to cities, agriculture, and adaptation in Africa and the Asia-Pacific region.
This report highlights eight years of START’s Africa Global Environmental Change (GEC) Grants Program, focusing on the significance and development of the program for GEC research in Africa and the major accomplishments of grant award recipients from 2004 to 2012.
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.
USGCRP supported several regional workshops in October 2014 as part of the Climate Change Preparedness and Resilience Exercise Series. This brochure was used for the first workshop, which focused on Houston-Galveston, Texas.
