Except that everyone acknowledges that there's been no warming since 2000.
I'm sure that 10,000 years ago, the hominids were worrying about the end of the ice age. Consider that most people's sense of "normal" extends from whatever conditions existed when they were 18 years old. Since rap music didn't exist when I was 18, all rap is completely worthless in my mind, and needs to go away for the world to be restored to the conditions when I was 18. Oh, the music those young kids listen to! (excepting of course that people now my age were saying the same thing back then.)
Basically, all this worrying about AGW is simply overwrought Christian guilt. "Oh noes! We've changed the world! We're guilty, God, punish us!" The sensible thing to do is to carry on and keep calm, and address problems as we find them ... just like we've always done. But that would disappoint a lot of people, because it's fun to be in crisis mode.
