The positive trend in soil temperature-moisture relations was observed at monitoring sites in the Yakutsk area, regardless of vegetation and soil type. The increase in soil temperature appears to have started in response to the large amounts of snow that accumulated in the winter of 2004. The consecutive positive anomalies of snow depth and rainfall, which occurred widely in the central and southern Lena River basin during the folowing three years, increased soil moisture and appear to have altered the active-layer thermal properties, which likely induced widespread warming of the surface layer of permafrost in this region
