Abstract
The work presents the results of the study of long-term changes in average seasonal surface air temperature in the Siberian region for the last 43 years (from 1973 to 2015), as well as for the periods from 1973 to 2005 (when there was the most intense global warming) and from 2006 to 2015 (the period of global warming slowdown or even a cooling in some regions). It is shown that winter and spring seasons have made major contribution to the rise in surface air temperature over the territory of Siberia during the period from 1973 to 2015. A cooling in the Arctic regions of Siberia in the winter season, as well as a cooling in the Western Siberia and in the south-western part of Eastern Siberia in the autumn season made the greatest contribution to reducing the intensity of the warming over the last decade.
