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.
These State Climate Summaries were produced to meet a demand for state-level information in the wake of the Third U.S. National Climate Assessment, released in 2014. The summaries cover assessment topics directly related to NOAA’s mission, specifically historical climate variations and trends, future climate model projections of climate conditions during the 21st century, and past and future conditions of sea...
This document presents the policy-relevant findings of the Arctic Monitoring and Assessment Programme's 2015 assessments of short-lived climate forcers (methane, black carbon, and ozone).
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.
This technical background report serves as the basis for the Global Mercury Assessment 2013: Sources, Emissions, Releases and Environmental Transport (a summary for policymakers). It presents sources of mercury emissions to air and water, with the latest information on atmospheric and aquatic chemistry, fate, and transport.
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.
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.
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.
