‘Extreme heat belt’ will impact more than 100 million Americans: study

As record-high temperatures recently swept across several parts of the U.S. this summer, new data on heat risks forecast an “extreme heat belt” will emerge in large parts of the country by 2053. 

The heat model released Monday by researchers from the nonprofit group First Street Foundation estimates heat risks at the property level across the U.S. and how the intensity of hot days will change over the next three decades. 

The model identified the seven hottest days for any property this year and used that metric to determine how many of those days would occur in 30 years.
