Sen. Mike Lee (R-Utah) tore into the Green New Deal on Tuesday, stating on the Senate floor that the only thing needed to combat climate change is for Americans to “fall in love” and have “more babies.”

Lee, who has expressed doubt before over the climate science finding that human activity is the main driver of global warming, bashed a resolution laying out the tenets of the Green New Deal. The congressional resolution was introduced by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and Sen. Ed Markey (D-Mass.) last month.

“I’m not immediately afraid of what carbon emissions unaddressed might do to our environment in the near future, or our civilization or our planet in the next few years,” Lee said during a Senate debate. “I’m mostly afraid of not being able to get through this speech with a straight face.”

“I rise today to consider the Green New Deal with the seriousness it deserves,” he said tongue-in-cheek, before displaying a series of fantastical images on a nearby easel meant to suggest that the Democrats’ proposal shouldn’t be taken seriously at all.

One of the pictures featured a cartoon image of former President Ronald Reagan firing a machine gun while riding a velociraptor.
