The Baltic Sea is rapidly shallowing due to a rare climate anomaly

The Baltic Sea lost about 275 million tons of water in early February, with the level dropping 67 cm below the average (since 1886) due to strong easterly winds that pushed water into the North Sea through the Danish Straits.

Causes of the anomaly

This rare climate anomaly is caused by powerful easterly winds that forced water out of the Baltic Sea. The sea level has reached a historic low not seen since 1886.

Consequences for the region

The decrease in water level significantly affects hydrology, ecosystems, and shipping in the Baltic Sea basin. The low level complicates navigation for vessels, threatens coastal ecosystems, and may lead to water supply issues in coastal areas. Experts note that such events are becoming more frequent due to climate change.
