Delivering what his office described as “a major address and current assessment of the global climate change challenge,” Kerry acknowledged and bemoaned the success of those who question the notion of human-induced global warming. He compared skeptics to flat-earthers and decried what he called a “concerted assault on reason.”

“I believe that the situation we face, Mr. President, is as dangerous as any of the sort of real crises that we talk about – today we had a hearing in the Foreign Relations Committee on the subject of Syria, and we all know what’s happening with respect to Iran, and nuclear weapons and the possibility even of a war,” Kerry said.

“Well, this issue [climate change] actually is of as significant a level of importance, because it affects life itself on the planet,” he said.
