Streletskiy D., Anisimov O., Vasiliev A. 2014. Chapter 10 - Permafrost degradation, In Shroder J.F., Haeberli W. & Whiteman C. (Ed.), Snow and Ice-Related Hazards, Risks and Disasters, Academic Press, 2014, 303-344
Climatic changes over the last 50 years resulted in a decrease of permafrost extent, an increase of permafrost temperature, and deepening of the active layer in numerous locations across the Arctic and High Mountainous environments. Permafrost degradation poses serious impacts ranging from local changes in topographic and hydrologic conditions, impacts on infrastructure and sustainability of northern communities, changes to vegetation and wildlife dynamics, and to global impacts on climate system.
