The contemporary climate trends within the permafrost extent in Russia have been evaluated and mapped on the basis of synthesized meteorological data during the period from 1965 to 2010. The reasons of lagging of permafrost temperature trends from the trends of mean annual air temperature have been examined. The small-scaled maps of permafrost thermal stability under the contemporary climate warming have been worked out.
