In the coastal town of Kongiganak, sinking cemeteries prevent Alaskans from burying their dead in the ground. The village of Shishmaref, located on an island five miles from the western Alaska mainland, has eroded so much that it is contemplating total relocation. These communities are being plagued by permafrost that is thawing.]]> 2019-04-12 15:04:41 UTC https://padlet.com/sojeda1177/7fks2k9458xu/wish/351187022 jphillips5766 https://padlet.com/sojeda1177/7fks2k9458xu/wish/351189505 As the global thermostat rises more and more permafrost will thaw, releasing planet heating emissions. With those planet heating emissions trapping more warmth, more permafrost will thaw releasing more carbon dioxide and methane into the atmosphere; trapping us in cycle where the output enhances the original stimulus.]]> 2019-04-12 15:10:51 UTC https://padlet.com/sojeda1177/7fks2k9458xu/wish/351189505 imcroberts5173 https://padlet.com/sojeda1177/7fks2k9458xu/wish/351191322 2019-04-12 15:14:48 UTC https://padlet.com/sojeda1177/7fks2k9458xu/wish/351191322 imcroberts5173 https://padlet.com/sojeda1177/7fks2k9458xu/wish/351195076 "But in a region where temperatures can dip to 40 degrees below zero Fahrenheit, the Zimovs say unusually high snowfall this year worked like a blanket, trapping excess heat in the ground. They found sections 30 inches deep—soils that typically freeze before Christmas—that had stayed damp and mushy all winter. For the first time in memory, ground that insulates deep Arctic permafrost simply did not freeze in winter."]]> 2019-04-12 15:22:21 UTC https://padlet.com/sojeda1177/7fks2k9458xu/wish/351195076 jphillips5766 https://padlet.com/sojeda1177/7fks2k9458xu/wish/351196216 "findings suggest that methane released from low-latitude permafrost clathrates therefore acted as a trigger and/or strong positive feedback for deglaciation and warming.
