nova, "ever thought about emissions of heat-trapping gases?" It is a question of cause and effect. Does higher temps cause more heat trapping gasses or do the gasses cause higher temps. That is how I understand that part of the argument. Put together with common sense that the earth has heated and cooled before man had any influence on it. Cause may be the earth slightly closer to the sun or sun spots??? your gang was saying that we where entering an Ice Age a few years back. What happened to that?
I would like to know the answers before we make drastic changes in the way we do business and more study in a non histerical way is needed.
