During an interview with comedian Stephen Colbert last week Bob Lutz was asked if climate change is being caused by “sunspots”. He answered that “in the opinion of about 32,000 of the world’s leading scientists, yes.”

These 32000 people are not “the world’s leading scientists”. They are, as DeSmogBlog puts it, “a self-selected group of people whose science credentials are modest or non-existent and who are led by the man who was big tobacco’s leading apologist.”

Good job Bob Lutz, spreading global warming denialism while promoting an eco-friendly car. That’s brightness! No wonder GM is in such a mess.
