Hazards related to permafrost and to permafrost degradation
2011Rockfalls ( 0.1-1 M m3) can threaten valley inhabitants at very long distance from the source area. Permafrost is present in Alpine rockwalls at high elevation (e.g. above c. 3000 m and 3500 m a.s.l. on north- and south-facing slopes, respectively). Its climatically-driven degradation is probably one of the main triggers of recent, present and future ...

Climate extremes relevant for permafrost degradation
2020<p>During the past several decades, Arctic regions warmed almost twice as much as the global average temperature. Simultaneously in the high northern latitudes, observations indicate a decline in permafrost extend and landscape modifications due to permafrost degradation.

Climatic warming and the degradation of warm permafrost
Permafrost and Periglacial Processes, 1996Permafrost—a widespread constituent of the terrestrial environment—by definition is dependent upon the ambient temperature for its existence and properties. Thus, it is very sensitive to climatic changes. Simple relations based upon conductive heat transfer, with thawing and geothermal heat flow, are presented to predict the transient effects of ...
