General Motors Vice Chairman of Global Product Development Bob Lutz was just on The Colbert Report blaming global warming on sunspots and dissing his own Chevrolet Volt as a weak, unattractive car. I'll post the video here as soon as it's online.
UPDATE: Here's the video. Note to Bob for future reference - if you're going to greenwash, it's best not to come right out and deny the scientific consensus on global warming with a made-up number of people who believe in a kooky denial scheme. Kind of undercuts your alleged green credentials.
