Counties across the southern half of the U.S., especially those with large and socially vulnerable populations, will be much more exposed to wildfire, drought and extreme heat than other parts of the country as the region’s climate warms in the coming decades, according to new research from the U.S. Forest Service and Resources for the Future.
The report, “Changing Hazards, Exposure, and Vulnerability in the Conterminous United States, 2020–2070,” builds on the Forest Service’s 2020 Resources Planning Act Assessment, which makes 50-year projections on the conditions of renewable resources across the country’s forests.In the study, researchers identified the continental U.S. counties that are especially exposed to natural disasters stemming from water shortages, extreme heat and wildfires, as well as those with socially vulnerable populations. The study’s various models, based on rates of growth and warming, show communities from Arizona to Florida at particular risk as states in the southern half of the country are seeing booming populations, long-standing inequities in their communities and increasing climate-driven threats.
The models give researchers, federal agencies and states not just an idea of how at-risk a county is to those natural disasters, but also how communities living within them could be impacted as people continue to move in. Much of the risk for communities from all three types of natural disasters stems from population growth.
