CNN aired a segment on Wednesday morning on the “clean coal” debate. Highlights include commentary from Sierra Club coal guy Bruce Nilles, footage from the big Capitol Power Plant protest on Monday, and a clip of the Coen brothers ad that debunks the notion of “clean coal.”

But the real treat is Joe Lucas, vice president of communications for the American Coalition for Clean Coal Electricity, refusing to answer a question about whether or not the burning of coal contributes to global warming. “I don’t know, I’m not a scientist,” says Lucas.
