According to new data, an "extreme heat belt" that reaches as far north as Chicago is being constructed.
This corridor would impact more than 107million people in the next 30 year.
The report was released Monday by First Street Foundation.
It found that residents living in a column of America’s heartland, which stretches from Texas and Louisiana to the Great Lakes could see heat index temperatures exceeding 125 degrees Fahrenheit by 2053.
Climate change will cause a significant increase in heat index temperatures over 100 degrees across most of the country over the next 30 year.
It's already been a hot summer in Europe and the U.S.
Last month was the third-hottest July in the country since records began almost 130 years ago.
