T. Boone Pickens on global warming

Just had a fascinating hour-long interview with Texas oil magnate T. Boone Pickens, who has been active for years in Republican politics (he's backing Rudolph Giuliani's presidential run in 2008). Among the things we discussed was global warming. He said that global warming is not a theory, but a fact. He qualified that by saying that he believes we would have had some natural warming even if humans hadn't been burning hydrocarbons at a high rate for the last century or so, but that there can be no doubt that this is a real phenomenon, and we have a lot to do with it. We'll publish his full remarks in the Dallas Morning News on Sunday.
