TL;DR: Climate change strongly impacts regions in high latitudes and altitudes that store high amounts of carbon in yet frozen ground, and the authors show that the consequence of these changes is global warming of permafrost at depths greater than 10 m in the Northern Hemisphere, in mountains, and in Antarctica.

TL;DR: In this article, active layer thickness from nine sites with up to 29 years of gridded measurements located in the Tornetrask region, northernmost Sweden, was examined in relation to climatic trend.

TL;DR: In this article, in situ and satellite data shows evidence of different regional snow cover responses to the widespread warming and increasing winter precipitation that has characterized the Arctic climate for the past 40-50 years.

TL;DR: In this paper, the authors provide a snapshot of the permafrost thermal state in the Nordic area obtained during the International Polar Year (IPY) 2007-2009 Several intensive research campaigns were undertaken within a variety of projects to obtain this snapshot.

TL;DR: Terrestrial Arctic animals are likely to be most vulnerable to warmer and drier summers, climatic changes that interfere with migration routes and staging areas, altered snow conditions and freeze-thaw cycles in winter, climate-induced disruption of the seasonal timing of reproduction and development, and influx of new competitors, predators, parasites and diseases.
