摘　　要：Due to global climate change it is important to constantly monitor thecurrent climate state, observed trends and timely detection of their changes.The change in the hydrothermal regime has to result into changes innatural ecosystems. The analysis of long-term changes of mean annualtemperatures and annual precipitation in warm and cold seasons over1955-2017 years was carried out using data of the Davsha meteorologicalstation , 54, 35˚N., 109,5˚E. Significant warming in the Northern Baikalregion has been observed since 1990 and continues to the present. Theclimate is subcontinental with cool and short summers, frosty and longwinters. In the last decade, there has been a shift of the beginning somephenology seasons. This had an effect on the increase in the warm seasonof the year and the duration of the frost-free period (by 5 days from thelong-term average date). Spring comes earlier - for 3 days, summer andthe last frost - for 5 days, autumn comes later - for 2 days.
