Watch President Obama Making Fun of Climate Deniers

The president was once accused of “climate silence.” Not any more.

President Obama is getting cheekier in speeches that mention climate change. Earlier this month, he berated climate deniers at a commencement speech at the University of California at Irvine, comparing their view to the idea that the moon is “made of cheese.”

And now, speaking before the League of Conservation Voters Wednesday night, Obama fully cemented his role as the “mocker-in-chief” of climate deniers, to use Politico’s words. Here’s one part of the speech:

It’s pretty rare that you encounter people who say that the problem of carbon pollution is not a problem. In most communities and workplaces, et cetera, when you talk to folks, they may not know how big a problem it is, they may not know exactly how it works, they may doubt that we can do something about it. But generally they don’t just say, ‘No I don’t believe anything scientists say.’ Except, where? [asking the audience] In Congress!

Obama also mocked the idea that climate change is a “liberal plot,” and much more, getting plenty of laughs from the crowd. You can watch part of the speech above.
