Written by Lee Stevenson, sorry I am a lousy editor. I do not believe man contribute to changes in the climate. I believe things go in cycles and the climate change is a natural occurrence. That being said lets look at the other side of the coin.
In the 70s data seem to indicate there was a global cooling many had believed this was occurring because of that and they claimed we were headed for the next ice age.

They speculated variations in the earths rotation caused ice ages so we may be headed towards another ice age.
