Arctic Permafrost Leaking Methane at Record Levels

This article, which Scientific American posted on its twitter feed, should alarm us all. No matter what the cause, this is one of the serious indicators. Read. Take note.

The statement that concerns me most is, "The new study follows repeated warnings that even modest levels of global warming could trigger huge increases in methane release from permafrost."
