Bacterial bloom as the Earth thawed

Around 650 million years ago, the Earth entered into the Marinoan glaciation that saw the entire planet freeze. The "Snowball Earth" impeded the evolution of life. But as it warmed, biotic life began to flourish. A research ...

New marine sulfur cycle model after the Snowball Earth glaciation

The Sturtian Snowball Earth glaciation (~717-660 million years ago) represents the most severe icehouse climate in Earth's history. Geological evidence indicates that, during this glaciation, ice sheets extended to low latitudes, ...

Evidence for glaciation predating MIS-6 in southeastern Tibet

Southeastern Tibet is one of the most glaciated regions on the Tibetan Plateau both at present and during the Quaternary. Numerical dating of glacial deposits has allowed the establishment of a provisional chronology of Quaternary ...

An ice age lasting 115,000 years in two minutes

An international research team used a computer model to reconstruct the history of glaciation in the Alps, visualising it in a two-minute computer animation. The simulation aims to enable a better understanding of the mechanisms ...

Cracking the ice code

(Phys.org) —What happened the last time a vegetated Earth shifted from an extremely cold climate to desert-like conditions? And what does it tell us about climate change today?

Researchers find new information about 'Snowball Earth' period

It is rather difficult to imagine, but approximately 635 million years ago, ice may have covered a vast portion of our planet in an event called "Snowball Earth." According to the Snowball Earth hypothesis, the massive ice ...
