Carbon Dioxide Biggest Player in Thawing Permafrost

Carbon dioxide emissions from dry and oxygen-rich environments will likely strengthen the climate forcing impact of thawing permafrost on top of methane release from oxygen-poor wetlands in the Arctic, according to a study in Nature Climate Change led by Northern Arizona University assistant research professor Christina Schädel. Schädel’s meta-analysis of 25 Arctic soil incubation studies

USGS Assesses Carbon Potential of Alaska Lands

In comparison to the lower 48 states, Alaskan forests, wetlands and permafrost contain larger stores of carbon, according to the first-of-its-kind assessment recently completed by the U.S. Geological Survey, the U.S. Forest Service and the University of Alaska at Fairbanks. “This benchmark assessment establishes significant baseline information to better understand carbon dynamics in Alaskan ecosystems,”

Nature Study Reveals Rapid Ice-Wedge Loss Across Arctic

LOS ALAMOS, N.M., March 15, 2016—A new study of permafrost has found that the ice wedges forming the prevalent honeycomb pattern across the tundra appear to be melting rapidly across the Arctic, changing the hydrology of the region and accelerating the release of greenhouse gases with major implications for global warming. While the gradual warming

Fire and Ice: Gaging the Effects of Wildfire on Alaskan Permafrost

USGS scientists, in collaboration with researchers at the University of Minnesota and University of Alaska Fairbanks, have mapped belowground permafrost in areas of Alaska that have been affected by wildfire, years-to-decades after the fires occurred. “There has been global concern for many years about the effects of the warming climate on high-latitude permafrost and its

The Takuvik Joint International Laboratory and BNP Paribas Foundation Partner on Research of Permafrost Thaw

QUÉBEC CITY, Dec. 3, 2014—A Canadian and French consortium, coordinated by the Takuvik Joint International Laboratory and supported by the BNP Paribas Foundation, is launching its APT Project, for Acceleration of Permafrost Thaw By Snow‒Vegetation Interactions. This important research initiative studies how climate change is accelerating the thawing of permafrost, a phenomenon that is still poorly understood.
