Webb5 apr. 2024 · A Slushy Earth Seaweed fossils found in China dating from over 600 million years ago suggest ancient Earth was not as ice-covered as previously thought, according to new research released yesterday. The study sheds light on how life survived two of the planet's most severe global glaciation events. Webb4 apr. 2024 · In that vein, a new study by researchers from China and the UK is the latest to suggest 'Snowball Earth' wasn't completely covered in ice – and might have even exhibited habitable open-ocean conditions far away from the equator. Just what caused Earth to suddenly dip into an extended cold snap around 700 million years ago isn't all that clear.

Webb[1] Modeling studies of the Neoproterozoic snowball Earth offer two variations for snowball conditions, the original “hard” snowball Earth where the ocean is completely covered by sea ice, and an alternate slushball Earth or “soft” snowball, where there is an equatorial oasis of open water. We use the University of Victoria Earth System Climate Model to show that …
