There is a real risk that human-caused climate change will accelerate the release of carbon dioxide from forest and tundra ecosystems, which have been storing a lot of carbon for thousands of years. We don’t want to cross a critical threshold where this massive release of carbon starts to run on autopilot. Chris Field.

Methane is a greenhouse gas more than 30 times more potent than carbon dioxide. These findings do change our view of the vulnerability of the large sub-sea permafrost carbon reservoir on the ESAS; the permafrost “lid” is clearly perforated, and sedimentary CH 4 is escaping to the atmosphere. The permafrost under the ESAS—a 2.1

As areas with permafrost thaw and more old carbon is released, the carbon balance changes. Permafrost thaw will make potentially significant contributions to atmospheric concentrations of carbon more rapidly that previously thought, according to a new study published in the 28 May issue of the journal Nature.
