During CNN’s live coverage of the deadly Oklahoma tornado on Monday night, host Piers Morgan and Bill Nye speculated on the possible role of climate change in the disaster.

“As a scientist, when you hear about the size, scale, power, devastation of this tornado, what does it tell you about the ongoing debate about climate change?” Morgan asked his guest.

Nye said climate change has to be considered after a catastrophic weather event like the devastating tornado in Oklahoma. He also claimed 10 of the last 12 years are the “warmest years recorded.”

“Thunderstorms are driven by heat and a tornado is a super thunderstorm — result of a super thunderstorm. So you’ve got to figure that if there’s more heat driving the storm then there’s going to be more tornadoes. Now this is the kind of thing that is worth investigating,” he added.
