Let's see, diameter of earth is something like 8,000 miles. The very thin epithelium of breathable atmosphere is, what, 4 miles? Now stick a bunch of pipes into the earth and let them burn for a hundred years. Think Iraqi oil fires x a thousand burning for one hundred years. How is that going to affect the climate? Can we get the resident scientist on the courtesy phone please.
Excellent point. Also let's not overlook the suns role in this unfortunate debacle. I believe the sun contributes to the vast majority of global warming. You can't really blame the earth anymore than you can blame the bread when toast gets burnt. Think about it.
