Why is this useful?
This data accompanies the Killer Heat in the United States: Climate Choices and the Future of Dangerously Hot Days report to provide findings for the population exposed to different frequencies of future extreme heat days over time for different greenhouse gas emissions scenarios. Data are provided at the state level for the contiguous United States. Results include modeled historical data and projections for the number of people exposed to 7, 30, or 60 days per year above heat index thresholds of 90°F, 100°F, 105°F, and 120°F as well as the number of people exposed to off-the-charts days (when the temperature and humidity exceed the limits of the National Weather Service's heat index calculations) per year.
