CNN brought Bill Nye the Science guy to talk about the flooding in Louisiana and what can be done to help stop thing like that. 

Nye spoke about how climate change is a big reason for the storms and some of the things that can be done.

As the interview with Chris Cuomo was wrapping up, Nye took a swipe at CNN saying that they employe a "a climate change denier meteorologist."

Cuomo quickly got away from all that.
