GM Vice Chairman Bob Lutz was on the “Colbert Report” last night to talk about the new Chevy Volt, but a lot of the conversation ended up being about whether or not Lutz believes in anthropogenic climate change.

Colbert, on the Volt: “This is tantamount to admitting that we have to do something about global warming, sir. You are capitulating with the enemy. Why not just call this the Chevy Gore? You don’t believe global warming is real. You’ve said so.”

Lutz: “I accept that the planet is heated, but like many noted scientists I don’t believe in the CO2 theory.”

Colbert, continuing his shtick, suggests that it’s “just sunspot activity.”

Lutz: “In the opinion of about 32,000 of the world’s leading scientists, yes.”
