Al Gore, you've been a real inspiration. But a lot of other people who preach the global warming gospel aren't out to save the world. They're out to run it.

Al Gore is not just whistling in the wind. Global warming is for real. Every scientist knows that now, and we are on our way to the destruction of every species on earth, if we don't pay attention and reverse our course.

I think Al Gore has done a great service in making global warming cool. He's basically taken it from a nerdy, almost ignored issue to making it what it is - namely, a problem.

The biologists have essentially been pushed aside. Al Gore's just an opportunist. The person who is really responsible for this overestimate of global warming is Jim Hansen. He consistently exaggerates all the dangers.

Obama sounded like Al Gore on global warming. The more the case for man-made warming falls apart, the more hysterical Gore gets about an imminent catastrophe. The more public support his stimulus bill loses, the more Obama embraces fear-mongering.

Global warming is real - it is man-made and it is an important problem. But it is not the end of the world.
