On Wednesday’s broadcast of MSNBC’s “Morning Joe,” the Center for American Progress’ Christie Hefner said that Chicago’s sky-high murder rate could be blamed — at least in part — on climate change.

“Yes, last year we hit a record number of murders from guns [in Chicago],” Hefner, the former chairwoman and chief executive officer of Playboy Enterprises, said. “And this year we are already outpacing last year’s numbers. Now, there are contributing factors that are not under anybody’s control and may seem odd, but it is factually true. One of them is actually the weather. There is a dramatic increase in gun violence when it is warmer. And we are having this climate change effect that is driving that.
