That global warming is an established scientific fact, and that human activity (wholesale pouring of greenhouse gasses into the atmosphere from automobiles, coal-fired power plants, dozens of other sources) is either causing it, or is dangerously accelerating it, is also a scientifically established fact.

No, we are not "all doomed." But we will be if we keep doing what we're doing. That, too, is an established scientific fact.

Scientists say so. Auto manufacturers, power plants, and other businesses that might have to spend a little money to reduce or eliminate their contributions to atmospheric polution--and the politicians they own--say either that it isn't so, or "well, let's study it for a few more centuries."

Personally, I'll believe a scientist over a politician every time.
