Pruitt asks whether global warming “is a bad thing”

- By Dino Grandoni, Brady Dennis and Chris Mooney By Scott Wilson

As head of the Environmen­tal Protection Agency, Scott Pruitt has repeatedly questioned the scientific consensus that rising levels of carbon dioxide from human-fueled activity are warming the planet.

He’s now taking a different approach: Even if climate change is occurring, as the vast majority of scientists say it is, a warmer atmosphere might not be so awful for human beings, according to Pruitt.

“We know humans have most flourished during times of what, warming trends,” Pruitt said Tuesday during an interview on KSNV, an NBC affiliate in Las Vegas. “So I think there’s assumption­s made that because the climate is warming, that that necessaril­y is a bad thing. Do we really know what the ideal surface temperatur­e should be in the year 2100, in the year 2018? That’s fairly arrogant for us to think that we know exactly what it should be in 2100.”

Pruitt continued: “There are very important questions around the climate issue that folks really don’t get to. And that’s one of the reasons why I’ve talked about having an honest, open, transparen­t debate about what do we know, what don’t we know, so the American people can be informed and they can make decisions on their own with respect to these issues.”
