Subglacial weathering may have slowed planet's escape from snowball Earth

A new study led by researchers at the Earth-Life Science Institute (ELSI) at Institute of Science Tokyo challenges a long-standing assumption about Earth's most extreme ice ages. Using numerical geochemical models, the team showed that chemical weathering may have continued beneath thick continental ice sheets during the snowball Earth event, consuming atmospheric carbon dioxide (CO₂) and potentially prolonging global glaciation.
