Twenty-five percent of Americans don't believe in climate change, according to a recent poll, but in the words of John Oliver, "who gives a sh-t?"

A new government report issued last week warned that climate change is already here. The host stressed on Sunday night that regardless of the remaining skeptics out there, climate change is just not up for debate anymore.

"You don't need people’s opinion on a fact," Oliver said. "You might as well have a poll asking: ‘Which number is bigger, 15 or 5?’ or ‘Do owls exist?’ or ‘Are there hats?'"

“The debate on climate change ought not to be whether or not it exists,” he added. “It's what we should do about. There is a mountain of research on this topic.”
