Fire or Ice?

In a grumpy mood, as I look out another day of snow here in Seattle (we don't usually have snow during the winter in the Puget Sound area), I feel it is time to turn to the theory of the "snow-ball earth." This theory says that earths has at times been completely covered in ice for periods lasting millions of years.

The threat of global warming seems to be in the publics' mind much now a days, but the historical record shows that ages of cold and ice have the greatest negative affect on the plants, animals, and humans of Earth.

Let us all hope that we aren't missing the early warning signs of a big freeze in our rush to see a big fry.
