"As the Caspian Sea is a closed basin, level changes occur periodically. However, one of the unique features of the Caspian Sea is that the reasons for this are still not fully and unambiguously assessed by scientists," said Rasim Sattar-zadeh, head of the Environmental Policy Department of the Ministry of Ecology and Natural Resources, APA reports.
According to him, the main factor in changing the level of the Caspian Sea is the climate of its basin, and level fluctuations mainly depend on its water balance elements, ie the rivers that feed it and the amount of precipitation, as well as evaporation.
According to the ministry official, it is impossible to make a long-term forecast of sea level dynamics. Because none of the long-term level forecasts made so far has come true: "Given that the level of the Caspian Sea depends on many factors, there must be an accurate forecast and scenario of changes in these factors. I think it is necessary to be skeptical of such a long-term forecast, as there are many uncertainties in the factors that lead to level fluctuations."
Note that according to a study by German and Dutch researchers published in the journal Nature Communications Earth & Environment, the water level in the Caspian Sea will fall by 9-18 meters by 2100. This, in turn, will lead to a number of problems, including environmental consequences, as well as affect the economic and political stability of the region.
