GM boss: 'Global warming a crock of sh*t'

This kind of talk from General Motors (GM) boss Bob Lutz will depress a lot of greens, and plays right into stereotypes about the American obsession with gas-guzzlers. But it's actually encouraging in its own way, because despite his personal beliefs, Lutz is still steering his company (or at least building some new models) in the direction of energy efficiency. That's free markets for you.

UPDATE: A counterpoint: will energy efficiency actually help us reduce energy use, or does it fall victim to the Jevons paradox?
