Understanding Permafrost and Its Global Distribution Permafrost, a layer of soil that remains frozen year-round, covers an impressive 24% of the Northern Hemisphere. It stretches across wide swaths of ...

Oct. 16, 2020 — Sea floor sediments of the Arctic Ocean can reveal how permafrost responds to climate warming. Researchers have found evidence of past permafrost thawing during climate warming ...

"The most climate-stressed regions all contained permafrost, which is vulnerable to thaw as temperatures rise," researcher Sue Natali said.

Turetsky, INSTAAR’s director since January 2020, is bringing much-needed attention to the global consequences of thawing permafrost. The study also found that this abrupt thawing always involves ...

The widespread permafrost in this region, where soils currently store twice as much carbon as the atmosphere, is thawing. Scientists are using increasingly detailed climate models to investigate ...

“Nature is full of microorganisms.” Think of permafrost, a climate change time bomb spread across Russia, Canada and Alaska that contains three times the carbon that has been emitted since the ...

Another advantage this study offers is relatively high resolution—1km x 1km for 2001-2020—allowing the researchers ... a co-author on the study and lead of Permafrost Pathways at Woodwell ...
