Summer nights across the U.S. are warming twice as fast as summer days — and they can be dangerous to your health. That’s according to the independent researching and reporting collaboration Climate Central.

In most of the Indiana cities it studied, the average summer low temperatures have warmed by at least 1 degree since 1970. Indianapolis had the biggest increase where average summer low temps have gone up by more than 3 degrees.

Beth Hall directs the Indiana State Climate Office and the Midwestern Regional Climate Center. She said we generally think of the dangers of summer heat during the day — but changes in those overnight lows are a greater concern with climate change.

“Historically, that's when the temperatures cool off. That's when we could open the windows at night and we get a break from those oppressive daytime temperatures," Hall said.
