President Obama on Wednesday ridiculed those who question his administration's position on so-called global climate change, formerly known as "global warming," specifically accusing Congress of being anti-science.

Congress, the president told a crowd of roughly 800 environmentalists in Washington, differs from the average American in that the average American may not understand the science of global climate change, but doesn't deny it exists.

The average American, according to Obama, doesn't “just say, ‘No, I don’t believe anything scientists say.’ Except — where? — in Congress. Folks will tell you climate change is a hoax or a fad or a plot — a liberal plot.”

But certain members of Congress do, he added.

He continued, mocking Congress for opposing his administration’s attempts to enact measures aimed at curbing global climate change, adding admitted ignorance of the issue is a poor excuse.

“And then most recently, because many who say that actually know better and they’re just embarrassed, they duck the question,” he said, “They say, 'Hey, I’m not a scientist,' which really translates into, 'I accept that man-made climate change is real, but if I say so out loud, I will be run out of town by a bunch of fringe elements that thinks climate science is a liberal plot so I’m going to just pretend like, I don’t know, I can’t read.' ”

“I'm not a doctor either, but if a bunch of doctors tell me that tobacco can cause lung cancer, then I'll say, ?OK.' It's not that hard,” said Obama, much to the crowd's delight, adding “I've got a bunch of scientists at NASA and I've got a bunch of scientists at EPA.”

It's not the first time the president has ridiculed what he calls climate change "deniers" from the podium. Just two weeks ago Obama used a commencement speech at the University of California-Irvine to attack those who disagree with his position.
