GM to Lutz: Global warming is no crock

General Motors Chairman Bob Lutz may think that global warming is "a crock," but GM CEO Rick Wagoner made it clear at a press event Tuesday that GM doesn't share Lutz's views. Instead, Wagoner believes that global warming is a very real issue facing the planet and that automakers must take action.

"The comments weren't coming out of our company," Wagoner told The Detroit News at the event.

Wagoner continued by saying that average temperatures around the world are on the rise, and while there is no definitive evidence linking cars to global warming, it's GM's goal to reduce its vehicles' CO2 emissions.

Lutz defended his stance on global warming on GM's corporate blog last month, saying "My beliefs are mine and I have a right to them." However, Lutz insists that he shares GM's stance on "the removal of cars and trucks from the environmental equation."
