On Hardball, moments ago:

PAT BUCHANAN: Global Warming is now a hoax--

CHRIS MATTHEWS: Do you think Global Warming is a hoax?

BUCHANAN: I do think it's a hoax.

MATTHEWS: It's a hoax?

BUCHANAN: I think it goes up and down. The idea this is grave--

MATTHEWS: -- CO2 emissions, greenhouse gases, doesn't exist?

BUCHANAN: No, it does, of course it exists. The idea we're all gonna die of this is utter nonsense. It's a power transfer to governments here, and governments abroad.

MATTHEWS: And the motivation is what?

BUCHANAN: And the motivation is power. It always is in government.

MATTHEWS: So people like Al Gore have cooked this up to get what?

BUCHANAN: No, I think he believes it, Chris, like the Birthers believe it. He's just like they are. It's a religious belief with them.

Remind me again why this guy is on TV?

UPDATE: Here's the video.
