Phys.org / Reflooding the Aral Sea could prevent massive CO₂ emissions

About 90% of the Aral Sea has dried up. The exposed sediments have already released enormous amounts of carbon dioxide (748 megatons) since 1960. However, through restoration, the lake could once again become a carbon sink. ...
