🌍 Lake Baikal is 25 million years old. It holds 20% of the world's unfrozen freshwater. It is the deepest lake on Earth.
And it is unraveling.
The thermobaric pump that oxygenates its deepest waters depends on cold temperatures that are disappearing. Endemic diatoms are being replaced by ordinary species found in every pond. The sponge forests that filter the lake's water are dying from disease. Clear-cut logging bans lifted in March 2026.
A 6.7-million-year climate record is at risk.
