TL;DR: It is shown that terrestrial changes in summer albedo contribute substantially to recent high-latitude warming trends and the continuation of current trends in shrub and tree expansion could further amplify this atmospheric heating by two to seven times.

TL;DR: In this article, the authors presented revised estimates of permafrost organic carbon stocks, including quantitative uncertainty estimates, in the 0-3 m depth range in soils as well as for sediments deeper than 3 m in deltaic deposits of major rivers and in the Yedoma region of Siberia and Alaska.

TL;DR: In this paper, the authors presented 1m-deep measurements of soil organic carbon obtained at 117 locations in the North American Arctic region, which revealed that the carbon store in this region is larger than previous estimates suggest, and highly dependent on landscape type.

TL;DR: In this article, deep soil profiles containing permafrost (Gelisols) were characterized for organic carbon (C) and total nitrogen (N) stocks to 3 m depths using the Community Climate System Model (CCSM4).

TL;DR: In this paper, the authors examined the thermal effects of vegetation and snow on the heat and water fluxes within patterned ground systems in all five Arctic bioclimate subzones along an 1800 km trans-Arctic temperature gradient in northern Alaska and northwestern Canada.
