Based on the results of re-analyzes, climatic changes in air temperature in the eastern part of the Black Sea over the period 1950-2015 were studied. For the regions of the coasts of the Krasnodar Territory and Abkhazia, the results of re-analyzes are compared. Based on this comparison, the NCEP/NCAR re-analysis was selected, the results of which are closest to the other data sources studied for the selected region. According to the NCEP/NCAR re-analysis, climatic changes in the amplitude, frequency and duration of extreme temperature phenomena in the regions of the coasts of the Krasnodar Territory and Abkhazia over the period 1950-2015 were investigated. The analysis showed an increase in temperature since the mid-1970s, which accelerated in the late 1990s. Acceleration of temperature growth is accompanied by an increase in its interannual variability. The increase in air temperature and interannual variability is accompanied by an increase in the amplitude, number and duration of extreme events with anomalies of the positive sign. Interannual variability of extreme air temperature events characteristics is quite different for the neighbouring Krasnodar Territory and Abkhazia.
