CNN — Millions of Americans are about to be living in areas where temperatures will be above the threshold of the National Weather Services’ “extreme danger” category.  That is when the heat index is more than 125 degrees.  This year alone, about 8 million people in the US will face those brutal temps.

Worsening heat and humidity as a result of climate change will bring extremely dangerous heat indices to much of the United States in the next 30 years, increasing both the intensity and frequency of the hottest days of the year, according to a new study published Monday.

What is being called an “extreme heat belt” will stretch all the way from Texas to the Great Lakes.

It will impact other parts of the country as well. In the southern half of the country, the number of hottest days will grow to around 30 – meaning what was once the hottest week of the year will become the hottest month by the 2050s.
