US EditionCaspian Sea's rapid decline threatens endangered seals, coastal communities and industry, study warns
- In 2025, the Caspian Sea faces rapid water level decline, endangering ecosystems and human infrastructure.
- Rising global temperatures cause increased evaporation, outpacing water replenishment into the Caspian Sea.
- The study highlights significant habitat loss for species, including the Caspian seal and migratory birds.
- Researchers predict a 5-10 meter decline even if warming is limited to 2°C; in a high-emission scenario, it could reach 21 meters.
- Researchers urge dynamic conservation, regional cooperation, and reduced emissions to mitigate socio-economic and ecological repercussions.

Rapid decline of Caspian Sea level threatens ecosystem integrity, biodiversity protection, and human infrastructure
The Caspian Sea is the world’s largest landlocked waterbody, providing habitat for hundreds of endemic and migratory species, along with ecosystem services that sustain millions of people. Global warming is projected to drive declines in water levels of up to 21 m by 2100. Using geospatial analyses, we assessed the impact of sea level decline on habitats, protected areas, and human infrastructure. We show that a water level decline of just 5–10 …
Caspian Sea's rapid decline threatens endangered seals, coastal communities and industry, study warns
Water levels in the Caspian Sea—the world's largest landlocked water body—are getting lower, as hotter temperatures cause more water to evaporate than is flowing in. Even if global warming is limited to below 2°C, it is likely that the level of the Caspian Sea will decline by 5 to 10 m, but if temperatures rise further, water levels could drop by as much as 21 m by 2100.
