The question isn't whether the earth's climate is changing. It is. Its always changing. The question is whether, as many scientist contend, its mainly induced by human activity and MORE importantly whether these scientist can prove they are correct SCIENTIFICALLY or can they only offer their CONSENSUS. According to Michael Crichton, they can't prove it for the simple reason they cannot use a key element of "the scientific method", controlled, repeatable, experiments as is common in all "hard" sciences. http://www.s8int.com/crichton.html
