WASHINGTON - Global warming is caused primarily by humans and "nearly all climate scientists today" agree with that viewpoint, the new head of the National Academy of Sciences — a climate scientist himself — said Wednesday.

Ralph Cicerone's views contrasted with Bush administration officials' emphasis on uncertainty about how much carbon dioxide and other industrial gases warm the atmosphere like a greenhouse.

"Carbon dioxide in the atmosphere is now at its highest level in 400,000 years and it continues to rise," said Cicerone, an atmospheric scientist who left as chancellor of University of California-Irvine to become academy president this month. "Nearly all climate scientists today believe that much of Earth's current warming has been caused by increases in the amount of greenhouse gases in the atmosphere, mostly from the burning of fuels."

3. I don't even think it'll take that long

Imagine all the energy the global warming skeptics are using. That could solve the energy crisis as well!

6. So what happened?

Did we do that all by ourselves, or did we trigger it, like a pound of TNT can be used to trigger a "shotgun"-style fission bomb?

400,000 years stretches back across four "stadial periods" or what we call "ice ages", although they're really all part of the same big ice age. The Earth has been in an overall ice age for nearly 2 1/2 million years now; they abate for about 10,000 years and advance for 90,000.

Another glaciation advance is "due" soon anyway, but kickstarting an ice age is not the kind of achievement humanity should be striving for.
