U.S. Global Change Research Program

Created: 12/17/2010 - Updated: 3/02/2020


The U.S. Global Change Research Program’s mission is “to build a knowledge base that informs human responses to climate and global change through coordinated and integrated federal programs of research, education, communication, and decision support.” The Program produces assessments of climate change and its implications, participates in the U.S. Interagency Climate Change Adaptation Task Force, and provides educational materials to support climate literacy and educational development.


The U.S. Global Change Research Program (USGCRP) was established with the passage of the Global Change Research Act in 1990. The USGCRP is charged with coordinating scientific research within the Federal Government on global change and its potential implications for natural environments and communities. Federal departments and agencies that participate in the USGCRP include:

  • Department of Commerce  
  • Department of Defense
  • Department of Energy
  • Department of the Interior
  • Department of State
  • Department of Transportation
  • Department of Health and Human Services
  • Department of Agriculture
  • National Aeronautics and Space Administration
  • National Science Foundation
  • Smithsonian Institution
  • Agency for International Development
  • Environmental Protection Agency

Members from each of the aforementioned departments and agencies are on the Subcommittee on Global Change Research within the National Science and Technology Council.


The USGCRP provides assessment and educational materials for use by the public and private sectors.


As part of its mandate, the USGCRP produces global change impacts assessments every four years. The first – National Assessment of the Potential Consequences of Climate Variability and Change in the United States – was completed in 2000. The most recent – State of the Knowledge Report of Global Climate Change Impacts in the U.S. – was released in 2009. These assessments include impacts by geographic region and economic sectors.

In addition, the USGCRP led the production of the U.S. Climate Change Science Program’s 21 Synthesis and Assessment Products (SAPs), released between 2004 and 2009, concerning climate trends, impacts, and management options. The SAPs concerned with climate change adaptation include:

  • SAP 4.1 – Coastal Sensitivity to Sea‐Level Rise: A Focus on the Mid‐Atlantic Region
  • SAP 4.2 – Thresholds of Climate Change in Ecosystems
  • SAP 4.3 – The Effects of Climate Change on Agriculture, Land Resources, Water Resources and Biodiversity
  • SAP 4.4 – Preliminary Review of Adaptation Options for Climate‐Sensitive Ecosystems and Resources
  • SAP 4.5 – Effects of Climate Change on Energy Production and Use in the United States
  • SAP 4.6 – Analyses of the Effects of Global Change on Human Health and Welfare and Human Systems
  • SAP 4.7 – Impacts of Climate Variability and Change on Transportation Systems and Infrastructure

Educational Materials

The USGCRP created the Climate Change, Wildlife, and Wildlands Toolkit for Formal and Informal Educators in order to aid educators in communicating how climate change will affect the environment and how people can become “climate stewards.” The 2009 version of the Toolkit contains background information on climate change science, a video on projected climate impacts on wildlife and habitats, and 11 case studies in eco-regions throughout the U.S. containing regional impacts and adaptation strategies. The eco-regions include: Western Forests and Mountains, Western Coastline, Eastern Coastline, Gulf Coast, Pacific Islands, Caribbean, Great Lakes, Eastern Forests and Woodlands, Polar/Subpolar, Desert Arid, and Prairie Grasslands.

The USGCRP also released a guide called Climate Literacy: The Essential Principles of Climate Science, which contains details on climate change science and impacts and mitigation and adaptation strategies. The guide was developed through collaboration between federal agencies and non-governmental organizations.

Outcomes and Conclusions

The USGCRP is mandated to coordinate federal research on climate change and to assess global change in national assessments; the Third National Climate Assessment was released for public comment in 2013. The final version is expected in 2014. The USGCRP is also engaged in the development of a national climate change adaptation strategy as part of the U.S. Interagency Climate Change Adaptation Task Force.

The U.S. Global Change Research Program (USGCRP) coordinates and integrates federal research on changes in the global environment and their implications for society. The USGCRP began as a presidential initiative in 1989 and was mandated by Congress in the Global Change Research Act of 1990 (P.L.
