The bottom line is that Gore, Leo, and the Big Science community cried wolf and they were wrong.
As per all the dire warnings, Manhattan should be under water by now, there should be no ice in the artic anymore, temperatures should be hitting new highs every year, and hurricanes should have destroyed half of the nation by now (and this isn't much of an exaggeration, look at the comments after the 2005 hurricane season).
Nothing happened. Nothing close. And some things moved in the opposite direction.....more ice in the artic, less hurricanes, etc.
So please forgive me if I stop believing the hype.
