Abstract
The recent changes of climate and permafrost conditions are studied on the basis of the data of northern meteorological and permafrost stations located in various regions of Russia.
Everywhere on Russian territory a warming of the Climate and the upper part of the Permafrost was observed since the middle of 1960s. The Permafrost Monitoring data indicate an increase of the permafrost temperature for the last 15–20 years up to 2–1.5 °C in 3 m depth and up to 1 °C in 10 m depth. The probable increase of the temperature of the upper part of the permafrost of Western Siberia will amount to about 1 °C by 2020, and 1.5–2 °C by 2050.
Calculations (up to the year 2025) and small scale map-schemes of predicted permafrost thawing, distribution and changes of cryogenic cracking of the soils within Russia under a global climate warming were carried out. Predictions were done for peaty, clayey and sandy types. The zones of degrading and stable permafrost for different stow types and areas of decreasing frost soil cracking are identified within the territory of Russia.
