Abstract Fifty years have passed since the previous Polar Year (1957-1959). After the relatively cold climatic period of 1950-1960, the abrupt warming of air and ground temperatures was evident for the north of Russia. The geocryological observations suggest that the rise in ground temperature slowed down in the early 1990s: the recent trend of changes in geocryological conditions is uncertain. Ongoing and future permafrost research and modeling of permafrost evolution under the impact of climate change and man- induced development should be based on wide- ranging scenarios. Generally, the permafrost and climatic trends show that there will be no significant changes in geocryological conditions in the upcoming 20 to 25 years. The decreasing continentality of the climate can increase the extent of destructive cryogenic processes on the continent and in the coastal zone, especially in the case of significant impact caused by development. Cryogenic structure of permafrost will control significantly the activity of external processes.
