More climate debate stuff . . . . . in the LA Times this a.m.

Ancient woolly mammoth bones and grasslands locked in the Siberian permafrost are starting to thaw and could potentially unleash billions of tons of carbon dioxide into the atmosphere, accelerating global warming, a team of Russian and American scientists has concluded.

The area involved is vast — 400,000 square miles. If the permafrost continues to thaw and releases heat-trapping carbon dioxide, it could dramatically increase the 730 billion metric tons already in the atmosphere, the scientists said in a study published in today's issue of the journal Science.
