There's pretty good evidence the world has been warming up for at least 12,000 years when we had our last "Ice Age".
We don't know how much people have contributed, although it's a fair assumption we have.
We don't know how warm it will get or all of the consequences, either.

What we do know is that the public will respond to nothing less than panic mode to change their thinking.
Of course being Americans means we'll probably go whole hog stupid in what ever directions we choose.
Fortunately most of those directions will be harmless.

I'm all in favor of doing things in a logical manner to develop alternative energy.
Even if they find out the earth is producing more oil at a rapid clip, weaning our dependence on the foreign teat can only be a good thing.
Save oil for applications where it's most valuable, which is not home heating or producing electricity.

Except for government mandates, everyone will have to use their own brain to figure out how much they buy into the "Green" frenzy.
But that said, be happy the frenzy exists or we'd get nowhere.
