The world is getting hotter. ​July is off to a extremely warm start, while June was the hottest June on record:

NASA global mean June temperature is out! Guess what – it's been the hottest June on record. Definitely felt like that in Germany… #climatecrisis #FridaysForFuture pic.twitter.com/vkOFP22NNM — Stefan Rahmstorf (@rahmstorf) July 15, 2019

While the change might seem small (about 1 degree Celsius over the last century), the day-to-day effects will be felt in summer heat, with hotter days and hotter nights. But what sort of changes can you expect in the place where you live? This concerning interactive tool built by the Union of Concerned Scientists details how the frequency of extremely hot days will change over the the rest of the 21st century if little or no action is taking to curb climate change.

The tool maps out how the frequency of days exceeding a 90 degree heat index, a 100 degree heat index, a 105 degree heat index and an "off the charts" heat index will increase by midcentury (2036-2065) and by late century (2070-2099) across the US.

Take a heat index over 105 degrees. Currently, large parts of the south, southwest, and midwest experience 1-10 days in this range, while much of the northeast and west almost never reaches those temperatures.







But the report estimates that if no action is taken on climate change, that could change drastically by the end of the century, with nearly the entire country experiencing days over 105 regularly. Large areas of Florida and Texas could see well over 100 days per year of extreme heat:







The tool also shows what could be achieved if we took "rapid action" on climate change — still hotter, but not catastrophically so:







Meanwhile, "off the charts" heat — which means exceeding a roughly 127 degree heat index — could spread across the US by the end of the century if climate change is left unchecked:
