Permafrost temperature dynamics of West Siberia in context of climate changes
This paper presents data on the mean annual permafrost temperature dynamics at three monitoring sites in West Siberia (Marre-Sale, Urengoy, Nadym) in context of climate changes. Climatic data are also represented. It is found that during the last 30 years an increase in the mean annual permafrost temperature is well expressed. The minimum temperature increase has been recorded for bogs, the maximum - for peatlands. The limits of the mean annual permafrost temperature changes under the 1 °C annual air temperature increase. This rise can be about 0.1-0.25 °C in tundra zone, and 0.1-0.8 °C in forest tundra and north taiga zones.
