A government report released last Friday indicates that climate change could cause a 10% decline in U.S. GDP by 2100. But the impact will almost certainly not be felt evenly and will have uneven economic, and political, consequences. This series of maps, from an article published in Science last year, shows probabilistic economic impacts by county. The authors of the Science article note, "Combining impacts across sectors reveals that warming causes a net transfer of value from Southern, Central, and Mid-Atlantic regions toward the Pacific Northwest, the Great Lakes region, and New England. In some counties, median losses exceed 20% of gross county product (GCP), while median gains sometimes exceed 10% of GCP. Because losses are largest in regions that are already poorer on average, climate change tends to increase preexisting inequality in the United States. Nationally averaged effects, used in previous assessments, do not capture this subnational restructuring of the U.S. economy."
