Al Gore, where were you?

WASHINGTON - Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests. The human population at that time was reduced to small isolated groups in Africa, apparently because of drought, according to an analysis released Thursday.

It looks like climate change may have threatened human existence without our assistance all those years ago. Imagine "the environment" being so unfriendly without us screwing it up. And here we thought global warming was only because of us human beings.

The article goes on to explain that

Eastern Africa experienced a series of severe droughts between 135,000 and 90,000 years ago and the researchers said this climatological shift may have contributed to the population changes, dividing into small, isolated groups which developed independently.

Lots of scientists have been saying that our "global warming" has more to do with changes in nature, rather the screw-ups by us humans. All the political arm-twisting coming from "green" groups, or Al Gore's crusade have more to do with politics than with "solving a problem." If the problems in nature, then let's focus on that, not on government or business.

The mere fact that climate changes occur does not imply that people, governments of businesses are at fault.
