Sen. Marco Rubio (Fla.), a Republican presidential hopeful, said in an interview broadcast Sunday that he does not believe human activity is causing “these dramatic changes to our climate the way these scientists are portraying it.”

“I don’t agree with the notion … that somehow, there are actions that we can take today that would actually have an impact on our climate,” Rubio said on ABC’s “This Week.” “Our climate is always changing.”

“I don’t know of any era in world history where the climate has been stable. Climate is always evolving and natural disasters have always existed,” he said.

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