jeckyl, i am a conservative who does not buy into global warming but i truly admire your tenaciousness in ferreting out the truth of this matter. i will be interested to see what else you come up with. you can educate all of us. my only qualm with this issue is that while it is still hotly debated in the scientific community, we are proceeding as if it is gospel truth, issuing carbon credits and legislating corporate sanctions which cause a nightmare bureaucracy, seriously affecting our economy, before all the facts are in. as you said, climate changes over a very long period so how can we know what is really happening in such a short time? keep us informed...and golf pro thanks for the topic...
