USGCRP Publications Print E-mail

The U.S. Global Change Research Program (USGCRP) delivers a variety of publications that highlight scientific advances pertaining to global change. In addition to detailing scientific progress, USGCRP products illustrate the impacts of global change and highlight the Nation’s response to these changes. As mandated by Congress, the USGCRP produces regular assessments of global change and annual reports showcasing the Program’s progress in achieving its annual goals. Below are some descriptions of recent USGCRP publications.

Scientific Assessments

According to the scientific assessments are evaluation and consensus building processes for establishing an integrated view of recent scientific breakthroughs and providing policy-relevant information to decision makers.

An assessment can establish the importance of an issue, provide an authoritative resolution of policy-relevant scientific questions, demonstrate the benefits of policy options, identify new research directions, and provide technical solutions.

The assessment process in itself is a key interface between science and policy and a crucial mechanism by which science informs policy making. For assessments to be effective and credible, the process has to be open and must provide accurate, useful, and scientifically tested information.

Annual Report to Congress

Since 1989, USGCRP has produced Our Changing Planet, an annual report that summarizes recent programmatic achievements, near-term plans, and progress in implementing long-term goals.

The report is required under the provisions of the Global Change Research Act of 1990  and summarizes recent achievements, near term plans, and progress in implementing long term goals. It also provides an overview of recent and near-term expenditures and of requested funding. To download Our Changing Planet reports, please visit the USGCRP Resource Library.

Synthesis and Assessment Products (SAPs)


From 2002 to 2008 the USGCRP was known as the U.S. Climate Change Science Program (CCSP). The CCSP created a series of 21 Synthesis and Assessment Products (SAPs) which integrated research results focused on important science issues and aimed to support informed discussion and decision making regarding climate variability and change by policy makers, resource managers, stakeholders, the media, and the general public.

The thirteen USGCRP participating Agencies led the production of these reports which were prepared in conformance with the provisions of the Data Quality Act (Section 515 of the Treasury and General Government Appropriations Act of 2001). To download the 21 Synthesis and Assessment Products please visit the USGCRP Resource Library.

Scientific Assessment of the Effects of Global Change on the United States

In May 2008, the National Science and Technology Council (NSTC), together with the U.S. Climate Change Science Program (CCSP) released a national scientific assessment of the effects of global change in the United States, with special emphasis on climate change.

The assessment analyzed the effects of global change on natural and human environments, agriculture, water resources, social systems, energy production and use, transportation, and human health. It analyzed current trends in global change, both natural and human-induced, and it projected major trends for the future. It was intended to help inform discussion of the relevant issues by decisionmakers, stakeholders, and the public. To download this report, please visit the USGCRP Resource Library.

USGCRP Resource Library

The purpose of the USGCRP online Resource Library is to provide access to information on climate change research, adaptation/mitigation strategies and technologies, and global change-related educational resources on behalf of the various U.S. Federal Agencies that are involved in the USGCRP.
