Subglacial Weathering May Have Slowed Earth’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 […]

Four-million-year Marinoan Snowball Shows Multiple Routes To Deglaciation

Twice during the Neoproterozoic Era, Earth experienced runaway ice-albedo catastrophes that resulted in multimillion year, low-latitude glaciations: the Sturtian and Marinoan snowball Earths.
