The Earth’s rotation is already slowing down, thanks to the influence of the Moon. Sure as hell, the media will hide that fact and blame it on GW.
Actually, Earth's rotation has sped up! The tsunami of 2004 (or was it 2005?) sped up the Earth's rotation by three microseconds due to a rearrangment of mass. It's all George Bush's fault of course.
I also think we should start blaming all natural disasters on Al Gore (why not?) Any hurricane, landslide, earthquake, etc. from now on will be AL Gore's fault! After all, he's the guy who is always proclaiming that disaster is just around corner. Al Gore, the harbinger of doom and gloom.
