The analysis of average annual surface air temperatures for 1976–2021 in the Trans-Baikal Territory makes it possible to distinguish three periods with different warming rates. The most intensive temperature rise was registered in 2011–2021 (1.33°C/10 years). In 1976–1995, the increase was 0.88°C/10 years, while the average annual temperature was not rising during 1996–2010. For the entire analyzed period, the number of days with positive and large positive anomalies of average daily surface air temperature increased significantly, and the one with negative and large negative anomalies decreased. Possible consequences of the changes for the regional economic activity are shown.
