Atmospheric layers driving accelerated far North warming

Laura Nielsen for Frontier Scientists – Recent research published in Nature Geoscience states that the largest contributors to warming in the Arctic are the region’s distinct surface temperatures coupled with the Arctic atmosphere’s prevailing vertical temperature structure. The research suggests that diminished snow and melting ice cover, previously thought to have the largest impact on […]

Geologic methane seeping from thawing cryosphere

Geologic methane is seeping through the edges of thawing permafrost and receding glaciers in Alaska and Greenland, according to a study recently published in the journal Nature Geoscience. University of Alaska Fairbanks researcher Katey Walter Anthony led the study, which, for the first time, documents the widespread occurrence of these terrestrial sources of geologic methane […]
