Marco Rubio doesn’t think human behavior is causing the world’s climate to significantly change.

“I do not believe that human activity is causing these dramatic changes to our climate the way these scientists are portraying it,” the Florida Republican senator told ABC’s “This Week” in an interview that aired Sunday.

“And I do not believe,” Rubio continued, “that the laws that they propose we pass will do anything about it, except it will destroy our economy.”

Saying that the global climate “is always changing,” Rubio said scientists had taken “a handful of decades of research” and called it “evidence of a longer-term trend that’s directly and almost solely attributable to manmade activity.”

Nick Loris, the Herbert and Joyce Morgan fellow at The Heritage Foundation, said Rubio was “spot on in saying climate regulations will do much more to harm our economy than combat climate change.”

“Despite Congress’s rejection of cap-and-trade proposals,” warned Loris, “the administration is moving forward with the regulatory equivalent that will drive up energy prices for American families and businesses, reducing income and destroying jobs in the process.”

Last week, the Obama administration released the National Climate Assessment.
