Post monthly temperatures and sea leve rises here. This will be a good place to put data or news on global warming.

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.
"It's like taking food out of your freezer … leave it on your counter for a few days, and it rots," University of Florida botany professor Ted Schuur said in a phone interview from Alaska, describing the process by which decaying animal and plant matter in the soil is converted by bacteria into carbon dioxide, methane and other greenhouse gases.
The research team concluded that previous studies on global warming had not taken into account the deep carbon reserve trapped in permafrost in the northern plains of Siberia and central Alaska.
The scientists said what was most surprising was the size and depth of the terrain that could be affected — a piece two-thirds the size of Alaska and an average of 80 feet deep containing about 500 billion metric tons of carbon.
