We know there were animals during Earth’s chilliest era—but we still don't know what they look like. By Chris Baraniuk / Hakai Magazine Published Dec 23, 2022 6:00 PM EST This article was originally ...

We have an extremely incomplete picture of what these snowball periods looked like, and Antarctic terrain provides different models for what an icehouse continent might look like. But now, researchers ...

When the Earth froze over, where did life shelter? MIT scientists say one refuge may have been pools of melted ice that dotted the planet's icy surface. Snowball Earth defines periods of our planet's ...

For nearly 60 million years, our home planet was likely frozen into a big snowball. Now, scientists have discovered evidence of Earth's transition from a tropical underwater world, writhing with ...

650 million years ago, Earth was covered in ice during an "extreme" 15-million-year-long ice age. New research suggests that towards the end this period, Earth may not have been fully frozen, however.

Scientists think Earth may have undergone at least two extreme freeze events throughout its history, becoming a so-called “snowball Earth” with a surface covered by ice. What triggered these events is ...

For billions of years bacteria dominated the globe, but at some point a major transition occurred and complex multicellular life began to take hold. The when and why of this transition has been the ...

Research by University Professor Richard Peltier of physics reveals that the Earth’s surface 700 million years ago may have been warmer than previously thought. Peltier developed a climate model that ...

Life on our planet faced a stern test during the Cryogenian Period that lasted from 720 million to 635 million years ago when Earth twice was frozen over with runaway glaciation and looked from space ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

When we think of the Ice Age we usually think of the Pleistocene era, which ended roughly 12,000 years ago. But that was a balmy summer compared to what happened about 700 million years ago, when ...
