Mankind caused the global warming, so mankind must employ draconian measures to fix it. Al Gore told us the science of global warming is settled. So why hasn't the entire scientific community fallen into step?

Can a reputable scientist be a "denier?" If the evidence of man-caused global warming is as overwhelming as the left claims it is, why the lack of rational, intelligent public debate between qualified people of opposing views? Doesn't this make more sense than believers simply brushing off deniers?

Given the chance, wouldn't believers want to publicly articulate their overwhelming scientific evidence and silence the naysayers or "deniers" once and for all?

The reason this hasn't happened is because the science is not settled. Man-caused global warming isn't scientific fact; it's an article of faith for the left -- the stuff of belief. In the realm of global warming, environmentalism has become a faith-based movement not unlike Christianity.
