Current Events » in reply to A great reason to vote for Bush - No global warming.

Precession of the Earth's axis
Nutation of the Earth's axis
Variation of the Sun's output
Plate tectonics and the structure of the continental and ocean crust
Volcanism

All of these have huge effects that we will NEVER be able to do a thing about.

The Earth's climate changes, as geological records show. It was generally mild EVERYWHERE, even in Antarctica, however there was always considerable variation. The current Ice Age is not without precedent.
