If you’re trying to beat the heat, you’re far from alone. More than 85 million Americans are under excessive heat warnings and heat advisories on Sunday, and many places in the Northeast will likely match or break record-breaking high temperatures, according to the National Weather Service.

The heat wave stretches from the mid-South up through the mid-Atlantic and Northeast. In many places, temperatures were approaching triple digits, prompting warnings and emergency measures by officials in multiple states.

While summer is traditionally the season for heat, the temperatures people are experiencing today are not the same as those from decades past.
