Global Change Research Program

The Global Change Research Program coordinates federal scientific assessment and synthesis on climate change, carbon cycle, land use change, biodiversity loss and related global-scale transformations. It produces interagency reports that inform policy deliberations in forums such as the United States Congress, United Nations Framework Convention on Climate Change, Intergovernmental Panel on Climate Change, and regional bodies like the Arctic Council and European Environment Agency. The program engages researchers affiliated with institutions such as the National Aeronautics and Space Administration, National Oceanic and Atmospheric Administration, National Science Foundation, Department of Energy, and United States Geological Survey.

Overview

The program serves as an umbrella coordinating activity among agencies including Environmental Protection Agency, Department of the Interior, Department of Agriculture, United States Fish and Wildlife Service, Centers for Disease Control and Prevention, and research laboratories such as Lawrence Berkeley National Laboratory, Los Alamos National Laboratory, and Pacific Northwest National Laboratory. It synthesizes evidence from observational networks like Global Change Research Act of 1990-mandated assessments and satellite missions such as Landsat, Terra, Aqua, and Suomi NPP. Outputs inform stakeholders including State of California, City of New York, World Bank, International Monetary Fund, and multinational initiatives like Project Drawdown and United Nations Environment Programme programs.

History and Development

Origins trace to scientific initiatives in the late 20th century influenced by events and actors such as the 1972 United Nations Conference on the Human Environment, the Montreal Protocol, the Brundtland Commission, and publications by researchers affiliated with Scripps Institution of Oceanography, National Center for Atmospheric Research, and Columbia University. Legislation and reports from offices like the Office of Science and Technology Policy, commissions including the interagency committees, and key figures from James Hansen-era debates catalyzed formal programmatic structures. Major milestones intersected with programs such as NASA Earth Science Division campaigns, International Geosphere-Biosphere Programme, and the launch of the Global Earth Observation System of Systems concept.

Research Themes and Objectives

Primary themes encompass atmospheric composition studies linked to Keeling Curve research, cryosphere investigations exemplified by work on Greenland Ice Sheet and Antarctic ice shelves, oceanography studies referencing Atlantic Meridional Overturning Circulation and El Niño–Southern Oscillation, terrestrial carbon dynamics with emphasis on Amazon Rainforest and Boreal forests, and human dimensions research involving urbanization case studies such as Los Angeles and Beijing. Objectives include integrating models from centers like Hadley Centre and National Center for Atmospheric Research, improving Earth system models used by IPCC authors, enhancing observational networks like Argo and FluxNet, and supporting vulnerability assessments for regions such as the Gulf Coast, Sahel, and Southeast Asia.

Organizational Structure and Funding

The interagency governance comprises representatives from agencies including Department of State, National Institutes of Health, Department of Transportation, National Oceanic and Atmospheric Administration, and Department of Energy. Funding streams originate from congressional appropriations appropriated to agencies such as Civilian Research and Development Foundation-partnered grants, competitive solicitations through National Science Foundation, programmatic budgets at Department of Energy Office of Science, and mission directorates at NASA. Research is executed by universities including Harvard University, Massachusetts Institute of Technology, University of California, Berkeley, Princeton University, University of Michigan, and international collaborators like Met Office and Potsdam Institute for Climate Impact Research.

Major Programs and Initiatives

Major initiatives include national assessments drafted under mandates similar to the Global Change Research Act of 1990, sustained observation networks such as National Ecological Observatory Network and Long Term Ecological Research Network, model intercomparison projects like CMIP ensembles coordinated with World Climate Research Programme, and decision-support tools developed in collaboration with Federal Emergency Management Agency and U.S. Army Corps of Engineers. The program partners with initiatives like Climate Resilience Toolkit, Urban Climate Change Research Network, Sustainable Development Solutions Network, and regional programs such as the Great Lakes Restoration Initiative and Coral Triangle Initiative.

Key Findings and Impact

Assessments have contributed to conclusions about anthropogenic forcing consistent with studies by Intergovernmental Panel on Climate Change authors, attribution research led by teams from NOAA and NASA, and paleoclimate reconstructions involving Ice core data from Vostok Station and Dome C. Findings influenced policy decisions related to emissions pathways discussed at Conference of the Parties, adaptation planning in jurisdictions like Florida and Bangladesh, and infrastructure standards adopted by American Society of Civil Engineers. The program’s outputs informed economic analyses by National Academies of Sciences, Engineering, and Medicine, risk assessments used by World Health Organization, and litigation referencing expert reports in courts such as those in State of California.

Challenges and Future Directions

Challenges include coordinating across entities with mandates represented by agencies like Department of Commerce and Department of Defense, addressing funding volatility tied to congressional appropriations and executive priorities, and integrating heterogeneous data from platforms including Copernicus Programme satellites and community-led campaigns such as Citizen science initiatives partnered with institutions like Smithsonian Institution. Future directions emphasize expanded use of high-resolution modeling from centers like Lawrence Livermore National Laboratory, increased engagement with indigenous knowledge holders in regions such as Alaska and Amazon Basin, and enhanced decision-relevant science for sectors including agriculture stakeholders, coastal managers in the Gulf of Mexico, and public health officials in WHO-linked networks.
