Abstract. The results of our observations, published and archival data of the permafrost temperature in the Western Arctic are presented. Long-term trends of the Permafrost temperature increase have been determined for 16 key sites on the coast of the Barents and Kara Seas. For the Barents Sea coast, the average temperature rise trend was 0.028 °C/year. For the Kara Sea, the average trend reaches 0.056 °C/year. GIS-oriented maps of the Permafrost temperature trends in Western Arctic have been developed. It has been found that trends remain unchanged on the coast of the Barents Sea, in the contrast, trends tend to increase on the Kara Sea coast. Keywords: Western Arctic, permafrost, temperature, temperature trends.
