Ancient air bubbles shed light on greenhouse gases
by Laughing Boy at 8:42 pm EST, Nov 26, 2005

Seems the latest analysis from core samples of Antarctic ice dated 650,000 years old "not good" for those still convinced the rise in atmospheric CO2 levels to be a "natural" trend...

"Levels of carbon dioxide have climbed from 280 parts per million two centuries ago to 380 ppm today.

Skeptics sometimes dismiss the rise in greenhouse gases as part of a naturally fluctuating cycle. The new study provides ever-more definitive evidence countering that view, however.

A previous ice-core sample had traced greenhouse gases back about 440,000 years. This new sample, from East Antarctica, goes 210,000 years further back in time.

Today's still rising level of carbon dioxide already is 27% higher than its peak during all those millennia, said lead researcher Thomas Stocker of the University of Bern, Switzerland.

'We are out of that natural range today,' he said."

Not good, but also not possible to tell everyone "stop burning fossil fuel NOW!" and no one is suggesting that. But the big corporations resisting change are running out of excuses.

How about we just put out a few coal mine fires instead?
