U.S. Global Change Research Program

U.S. Global Change Research Program. The U.S. Global Change Research Program is a federally mandated initiative that coordinates and integrates scientific research on changes in the global environment and their implications for society. Established by the Global Change Research Act of 1990, it represents a collaborative effort across the executive branch to understand, assess, and respond to climate change and related global shifts. The program is renowned for producing authoritative, consensus-based assessments, most notably the National Climate Assessment, which inform public and private decision-making at all levels.

History and establishment

The origins of the program trace back to the late 1980s, driven by growing scientific consensus on issues like ozone depletion and increasing atmospheric concentrations of carbon dioxide. Key legislative action occurred during the administration of George H. W. Bush, culminating in the passage of the Global Change Research Act of 1990, which was signed into law as part of a broader fiscal year appropriation. This act formally established the program, mandating a comprehensive and integrated United States research program to assist the nation and the world in understanding, assessing, predicting, and responding to human-induced and natural processes of global change. Early foundational work was influenced by international scientific efforts like the Intergovernmental Panel on Climate Change and reports from the National Academy of Sciences.

Organizational structure and participating agencies

The program operates under the auspices of the Executive Office of the President of the United States and is overseen by the Subcommittee on Global Change Research, which falls under the National Science and Technology Council. The executive director, a position held by officials such as Michael Kuperberg, manages the day-to-day operations and interagency coordination. Participation involves thirteen federal agencies and departments, each bringing distinct expertise. Major contributors include the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, the United States Department of Energy, the National Science Foundation, the United States Environmental Protection Agency, and the United States Department of Agriculture. Other participants are the United States Department of Defense, the United States Department of the Interior, the United States Department of State, the United States Department of Transportation, the United States Agency for International Development, the Smithsonian Institution, and the United States Department of Health and Human Services.

Major reports and assessments

The program's most prominent and congressionally mandated product is the National Climate Assessment, a comprehensive report issued approximately every four years that details the impacts of climate change across United States regions and economic sectors. Other significant publications include periodic synthesis and assessment reports on specific topics, such as the impacts on agriculture and water resources. The program also contributes to and draws from major international assessments, including those of the Intergovernmental Panel on Climate Change. These documents undergo extensive peer review and represent a consensus of the federal and broader scientific community, serving as foundational references for policymakers, researchers, and educators.

Key research areas and programs

Research is organized around interconnected themes that span the physical, biological, and social sciences. A core focus is on the Earth's climate system, including atmospheric composition, ocean acidification, and changes in the cryosphere. Another major area involves understanding impacts and vulnerabilities on human health, infrastructure, ecosystems, and sectors like forestry and coastal management. The program also supports advanced modeling and integrated assessment to improve projections of future change. Significant interagency initiatives coordinated under its framework have included the Carbon Cycle Science Program, the U.S. Climate Variability and Predictability Program, and research on global carbon cycle and terrestrial ecosystems.

Impact and influence on policy

The program's assessments have played a critical role in informing climate policy and planning at multiple levels of government. Findings from the National Climate Assessment are routinely cited in congressional hearings, regulatory impact analyses by the United States Environmental Protection Agency, and state-level adaptation plans, such as those in California and New York. The scientific foundation it provides has influenced major policy developments, including the creation of the U.S. Climate Resilience Toolkit and has been referenced in international forums like the United Nations Framework Convention on Climate Change. While the program itself is designed to be policy-neutral, its authoritative science has consistently been used to underscore the urgency of mitigation and adaptation actions by administrations, legislators, and the Supreme Court of the United States in relevant cases.
