In his blog, General Motor’s vice chairman Bob Lutz has clarified his earlier comments about global warming being "a crock of s***." The outspoken GM leader, who has been a major force behind the development of the Chevy Volt, told a closed-door gathering of reporters a few weeks ago that “global warming is a total crock of s***,” according to D Magazine. Lutz’s recent blog entry doesn’t try to dispel those earlier reports. In an entry titled “Talk About a Crock…,” Lutz argues that his opinions on global warming don’t matter. What does matter, he says, is that “General Motors is dedicated to the removal of cars and trucks from the environmental equation, period.” D Magazine said that Lutz told the reporters “I’m motivated more by the desire to replace imported oil than by the CO2 (agument).” Lutz’s blog also appears to express surprise at the “people who have been spewing virtual vitriol in my direction.”
