Some Thermafrost thawing, and some resulting Methane gas can be trouble

Just a quick post. Scientific American has an article outlining some research into the methane gas being released from thawing thermafrost up in Alaska. If all of the thermafrost were to thaw out, tens of billions of tons of methane gas might be released. This is truly significant since methane outdoes carbon dioxide as a greenhouse gas by a factor of 25.
