NCA4 Vol I: Climate Science Special Report
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).

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).
The National Climate Assessment summarizes the impacts of climate change on the United States, now and in the future. A team of more than 300 experts guided by a 60-member Federal Advisory Committee produced the report, which was extensively reviewed by the public and experts, including federal agencies and a panel of the National Academy of Sciences. The report can...
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.
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 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 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.
