More than 100 million Americans will live in the ‘extreme heat belt’ by 2053, researchers say

After the United States experienced record heat waves this year, it looks like even hotter weather is set to consume huge swaths of the country for decades to come. More than 100 million Americans will live in an “extreme heat belt” by 2053, according to the nonprofit First Street Foundation. At least one day a year, areas of the belt will experience temperatures above 125 F, which is within the National Weather Service’s Heat Index Extreme Danger Level. The huge area that will be affected stretches from Texas to Wisconsin and also includes the southeastern United States. Although the regions of the belt are not normally considered the hottest parts of the United States, there are “no coastal influences to mitigate the extreme temperatures”, according to the researchers. explains the report, adding that many affected communities “are not acclimatized to warmer weather compared to their normal climate.” The most extreme heat increase is expected to occur in the Miami-Dade County area of ​​Florida, where the hottest days (currently reaching around 103 F) will drop from seven days per year to 34 by 2053.
