That's what confuses me, the Earth has always had a cycle of warm to cold, cold to warm, and only until recently (the past 40,000 years) has it remained relatively stable.

And many times in its history, it has flucuated every bit as fast, or faster, than it is now -- and cars/humans weren't even around. Yet it happens now and it's somehow humans fault.

Plus, so what? It's not like we're all going to put aside our fossil fuels tomorrow.

If these scientists spent half as much time trying to figure out how to make another form of energy as reliable and easy-to-use as fossil fuels as they do trying to prove their global warming theory, we wouldn't have this problem.
