The explanation for the disappearance of the Caspian Sea


The largest land mass on Earth, known as the Caspian Sea, is disappearing due to evaporation, and it seems scientists already know the reason for it. The Caspian Sea, which is located between Europe and Asia, during the last two decades has been to evaporate, due to the high temperatures, as a consequence of the climate change.

Researchers from the University of Texas have conducted analyzes, and found out that the Caspian Sea has been losing about 7 centimeters annually since 1996, and if this continues, it will reach a record low below that measured in 1970, and everything is due to climate change and the temperature increase was of about 1 Celsius degree.

Although there has been some variation in the sea levels in the last 100 years, none has been as significant as the current one, and it is thought that it is due to climate changes like the present ones.

The study discovered everything by chance, due to the team’s intervention in helping to calibrate GRACE satellite data that was put into orbit in 2002. During this procedure, they detected the extreme variation of the Caspian Sea, with multiple levels being detected for the water on this Sea, which led to a more in-depth analysis by the scientists.

After analyzing the data, the team found out that the effects of evaporation were much higher than the effects of the surrounding rivers, which means that evaporation occurs at a much higher rate than that of the inflow of water through these affluents.

The rate of evaporation is expected to increase following the expected rise in temperature due to global warming, and unless there is an increase in discharges from the affluents and precipitation in the area, eventually the Caspian Sea will disappear within about 75 years.
