if he'd said "Man-made Global Warming is a sham" would you still have called him an idiot?
I'm just wondering; because while I agree that much evidence points to a current warming trend in this latest era of Earth's history, I think MANY MANY MANY people are beginning to see that the theory that this warming is due to anything that mankind has done is ridiculous. The planet, in its millions of years of history, fluctuates in average temperature widely due to countless reasons, many still unknown. From solar flares to volcanic activity; there are forces effecting this planet much more powerful than all the result of human history.
While a blanket statement like "Global Warming is a Sham" may sounds short-sided, I don't think its fare to call anyone an idiot for listening to the reason in their head that doubts that burning coal, driving a car with bad gas mileage or using "old fashion" light bulbs can somehow effect our planet's climate in any sizable way.
Just saying.
