Caspian Sea Water Levels Drop to Historic Low

Water levels in the Caspian Sea have fallen to more than 29 meters below the Baltic Sea reference point, a historic low, exposing large areas of seabed in the northern region and threatening its ecosystems.

The current observation of historic low water levels in the Caspian Sea reinforces mounting concerns about the region's ecological future. Several previous observations document the cascading impacts of declining water levels and related environmental stressors: - Thousands of Endangered Seals Wash Up Dead on Russia's Caspian Shore (Dec 2022) reported a mass die-off of Caspian seals, an endangered species already stressed by decades-long population decline. The abstract noted that, beyond acute events—such as suspected pollution—long-term trends like "climate change-driven declines in water levels" threaten the already fragile seal population. - As the Caspian Sea Disappears, Life Goes on for Those Living by Its Shores (Apr 2021) previously highlighted projections that the Caspian Sea might shrink by a quarter by century’s end. Scientists cited increased evaporation rates due to higher surface temperatures as a cause, echoing those identified in the present post. The observation also emphasized the impact on endemic species and the human populations whose livelihoods depend on the sea. In a regional context, the Russian Cosmonaut Shares Unique Video of Shrinking Aral Sea as Seen From Outer Space (Jun 2022) draws attention to similar large-scale water losses in nearby inland lakes, underlining how human activity—such as river diversion and irrigation—has dramatically altered water availability and ecosystems.> A pattern emerges from these observations: climate trends (notably increased evaporation) coupled with reduced river inflows—largely due to damming and irrigation developments—are central to the shrinking of the Caspian. As outlined in both this observation and the 2021 post, the consequences reach from ecosystem collapse (notably affecting seals and sturgeon) to the exposure of the seabed and even the uncovering of ancient human infrastructure.
