Global Warming and our Changing World

I recently heard a Presidential candidate (it might have been John McCain) say that if we're wrong about Global Warming, we'll develop cleaner technology without really needing it. But if we're right, and take no action, the world will be in a horrible predicament.

So the point is, if we must be wrong, let's be the wrong where we took unnecessary action. Not the one where we didn't take the steps we should have.
