Global Warming is a scam (ask the friends of Stan Meyers). Was skeptical when Al Gore won the Nobel Prize, but with Obama winning one too... The temperature has always changed, some years worse than others. Occasionally, we get some extreme changes, but it corrects itself eventually. It's nothing we tiny humans did/doing, it's just natural.
Now, if we could find some way to effect the global temperature, it would be an escalating battle, which we would of course lose, and Al Gore's doom predictions would come true. And it would be our fault...
