Reconstruction of the summer (June-July) and mean annual air temperature for the last 2000 years for two subarctic regions of Siberia - north-east Yakutia and the eastern part of the Taimyr peninsula - has been carried out. According to the reconstruction data, synchronous and asynchronous extreme warming and cooling-off periods within the period studied were found. The performed analysis of long-term measurements of climatic conditions has demonstrated that during 2000 years, there have been clear-cut climatic variations in the annual ring chronology of global character (middle age accumulation, short glacial period, modern warming). It has been shown that in the East Taimyr and North-East Yakutia the summer air temperature in the XX century, as compared to XIX century, increased on the average by 0.5-0.6
