Well, you might be interested in an interview with someone who has vastly more credibility than AlGore, a man with years of experience in the field of climatology. It may well be that this man is right, and that the public has been fed a 'bill of goods' for less-than-honorable purposes by politicians eager to control their lives. Read the interview with Dr. Reid Bryson, a man who holds the 30th PHD ever granted in the field of Meteorology. Read his credentials, consider what he says, and then ask yourself why Al Gore refuses to debate anyone who holds an opinion at odds with his own.
You might also, if you're a thinking person who would rather make up your own mind, consider this article at the American Thinker that calls into question the motivation of those who would lead us back into the dark ages. Oh, and be sure to read the comments.
