Unexpected Future Boost of Methane Possible from Arctic Permafrost

New NASA-funded research has discovered that Arctic permafrost’s expected gradual thawing and the associated release of greenhouse gases to the atmosphere may actually be sped up by instances of a relatively little known process called abrupt thawing. Abrupt thawing takes place under a certain type of Arctic lake, known as a thermokarst lake that forms […]

New Permafrost Map Shows Regions Vulnerable to Thaw, Carbon Release

  A new mapping project has identified regions worldwide that are most susceptible to dramatic permafrost thaw formations, known as thermokarst, and the resulting release of greenhouse gases. University of Alaska Fairbanks researchers David McGuire and Vladimir Romanovsky were part of the project, which was led by University of Alberta researcher David Olefeldt. They found […]
