The US Could See a New 'Extreme Heat Belt' By 2053

An "extreme heat belt" reaching as far north as Chicago is taking shape, a corridor that cuts through the middle of the country and would affect more than 107 million people over the next 30 years, according to new data on the country's heat risks. From a report: The report, released Monday by the nonprofit research group First Street Foundation, found that within a column of America's heartland stretching from Texas and Louisiana north to the Great Lakes, residents could experience heat index temperatures above 125 degrees Fahrenheit by 2053 -- conditions that are more commonly found in California's Death Valley or in parts of the Middle East. The projections are part of First Street Foundation's new, peer-reviewed extreme heat model, which shows that most of the country will have upticks in the number of days with heat index temperatures above 100 degrees over the next 30 years as a result of climate change. The heat index represents what a temperature feels like to the human body when humidity and air temperature are combined. It is commonly referred to as the "feels like" temperature. "Everybody is affected by increasing heat, whether it be absolute increases in dangerous days or it's just a local hot day," said First Street Foundation's chief research officer, Jeremy Porter, a professor and the director of quantitative methods in social sciences at the City University of New York.
