Jon, As I mentioned previously, Gore readily acknowledges that he is by no means the first to deliver the message. He was first exposed to it by Prof. Roger Revelle about 40 years back. I don't think Al has actually done any scientific research recently into the issue. What he has done is packaged a presentation whioch has pulled much of the previous information together and presented it in a way that has helped clarify the issues for a much larger audiuence.
As for his personal carbon footprint, I think the energy use at his home has been overblown because it has compared the Gore residence with that of the residence for a comparably sized family. There is a lot more going on at the Gore home than family matters. It is also my understanding that he normally uses regularly scheduled commercial jets in most of his travel.
I find it very interesting that Gore (and Hilary Clinton) are viewed in such a polarized way.
