One could point out he got an Oscar, not a Nobel Prize for science. Also, one can point out that we typically think of Oscar's in the context of fiction. ;-p That being said, Gore is not acting; he believes fully in everything he claims is true, right or wrong. He believes in it so much he sacrificed his marriage for it so it must be important to him.

Some of his statistics might have been off but those who suggest his errors disprove there is Global Warming are using the precise same logic that says that because there was originally an over-count of how many Jews were murdered in the Holocaust that somehow proves there was no Holocaust and that it was all made up.

There is your Godwin's Law moment of the day. ;-p

Wish I had a dollar for every time that kind of story has been done (not even counting that science fiction movie by Al Gore   :)      ).
