This paper summarizes the results of research on long-term variability of anomalies of annual temperatures in the Tyva Republic. The climate in the region is sharp continental, characterized by large temperature variability, both in diurnal and annual course. Anticyclone dry and clear weather dominates over the territory of the region. Multi-year temperature trends calculated for each month served as a basis for analysis of annual cycle of temperature trends at each station for the period of 1961-2016. The average annual temperature amounted to -3.4 ± 1.1 °С (1961-1990). Precipitation distribution is varied, for warm period precipitation is higher 80-87 % (annual precipitation is 180-325 mm), and for cold period precipitation is very low, about 20-13 %. Global warming is accompanied by changes in regional climate and seasonal features. The average annual air temperatures during 1975-2005 represent the warmest years. This is also reflected in the trends of the average monthly, seasonal and annual air temperatures. When comparing the longterm average air temperature in the period of 1975-2016 with the 1961-1990 period, from November to March increased by 1.3 °С and from April to October – by 1°С. The first years of the 21st century were the warmest years in the history of meteorological measurements in republic. During the period of 2000-2016 was one of, in the cold season the temperature increased by 1.9 °С and in the warmer time of the year – by 1.3 °С. However, it was frosty during January. This trend indicates an increased risk of higher fluctuations of the air temperature in the republic.
