Climate variations have been registered in the Aral Sea area time and again. In recent decades the anthropogenic effect has become a significant contributing factor. It became prominent, firstly, due to global changes caused, in particular, by the growing level of greenhouse gases in the atmosphere, and, secondly, due to regional variations – shrinking of the Aral Sea area. The latter fact leads to growing continentality of the local climate. During the last century the mean annual air temperature in the Aral region has risen by more than 1°C. The most perceptible warming is recorded in the transitional seasons. Long-term data on precipitation have revealed their great year-to-year variability and some increase of the annual precipitation due to the growing precipitation in the cold season.
