Excerpts;
In this week’s issue of Nature a study led by Stockholm University, with collaborators from Russia, US, UK, Switzerland, Norway, Spain and Denmark, shows that an ancient and large carbon pool held in a less-studied form of permafrost (“Yedoma”) is thaw-released along the approximately 7000-kilometer desolate coast of northernmost Siberian Arctic…
“Coastal Yedoma is likely more vulnerable towards carbon release than other permafrost bodies as it is not only subject to thermal collapse from above but also to enhanced wave and wind erosion of the Yedoma-dominated coast brought on by sea-level rise and longer ice-free seasons…”
