Professor found a sharp change in the water level.
The researchers found the reasons for the sharp fall of the water level in the Caspian sea and believe that in the next 75 years, the Northern part of the reservoir can evaporate completely.
In recent years, observations have recorded a noticeable drop in water levels in many large lakes of the world. In 2015, scientists reported a record decline in water level in the lake. In 2016 completely disappeared, the second largest lake of Bolivia, and experts are not sure it will ever recover.
Gradually shallower and the Earth’s largest landlocked water body Caspian sea. The authors of a new study have studied the fall of the water level in the Caspian sea since 1979. Scientists conclude: in the future the water level will continue to fall due to global warming.
According to scientists, for twenty years the lake has lost about 7 inches of water annually. At this rate of shoaling, the water level could soon fall below the minimum values recorded in the late 1970s. the Researchers predicted a further shallowing of the reservoir based on the estimated levels of precipitation, evaporation and changes of river runoff in the Caspian sea basin.
Monitor the condition of the lake being the middle of the XIX century. During this time the water level several times fluctuating significantly. However, researchers believe that the nature of the changes of the last few decades differs from that recorded earlier.
The water-level fluctuations became more drastic. According to experts, global warming and the rise of the ambient temperature: it increases the evaporation of water. At the present level of evaporation the Northern part of the Caspian sea may completely disappear in 75 years.
According to the model drawn up by scientists, it is the evaporation of water was the most important factor affecting the level of the Caspian sea. The amount of precipitation and the volume of water in the surrounding rivers do not so much affect him.
