Fifth National Climate Assessment
2023
This report from the U.S. Global Change Research Program (USGCRP) discusses climate change impacts, risks, and responses in the United States, with a focus on its impact on human welfare and society. The report analyzes the current impact of climate change, how Americans have responded, indicators of change, and projected changes. It explores the effect of climate change on a wide range of factors: the natural environment, agriculture, energy, land and water resources, transportation, human health, human social systems, and biological diversity. The report disaggregates data by regions to explore climate trends based on location, and, where possible, illustrates climate risk reduction and resilience strategies with examples from communities across the U.S. The report provides a general overview of the risks and impacts of climate change in the U.S., and includes chapters on how climate impacts physical Earth systems (Ch. 2-3), a summary of current and future climate risks in the U.S. (Ch. 4-20), and details risks posed by climate change in different regions of the U.S. (Ch. 21–30).
