The thermohaline regime trends of the Black Sea basin in 2000–2021 were studied based on the data from three retrospective analysis (reanalysis) of the Black Sea hydrophysical fields. It is shown that the cumulative effect of an increase in average the sea surface temperature (SST) and the softening of winter conditions in the Black Sea area in recent 7–8 years leads to the record warming and then the disappearance of the ventilated Black Sea cold intermediate layer (CIL) in its traditional sense by 2020 year. In addition, accelerated warming of sea waters has been observed within the permanent (main) pycnocline in the last 7–8 years. Changes in the thermal regime of the upper sea layer are accompanied by a continued increase in salinity in the main pycnocline.
