There's a need for more educational outreach on extreme heat, especially in the midwest and southwest. Public opinion estimates from the Yale Climate Opinion Maps show that 65% of Americans were “very” or “somewhat” worried about global warming in the fall of 2021, with substantial county-level variation. Nationally, only 47% of Americans think they will be personally harmed by global warming. Of greatest concern are the counties primarily in the Midwest that have relatively high exposure to extreme heat but lower-than-average levels of worry about global warming. The 217 counties that fall into the “Higher Exposure, Lower Worry” category about 6.4M people (2.6% of U.S. population). Analysis of the socioeconomic characteristics of these counties show that they have a median household income of around $57K per year, which is about 9% below the overall median household income in the United States ($62K).
