How did complex life survive when Earth was frozen over? Scientists say tiny meltwater ponds on ancient ice may have been the key.

Anyone living on Earth between 720 million and 635 million years ago probably would've needed a jacket. Geologists have long ...

An artist's conception of "Snowball Earth," when the planet was either completely or largely covered in ice hundreds of millions of years ago. Even the balmy tropics may have once been crushed by ...

This is a vicious cycle that on other planets may have left it covered in ice forever. Over time, however, the CO2 levels built up on the Earth from volcanic eruptions and other sources.

All of which raises questions about what the snowball Earth might have looked like in the continental interiors. A team of US-based geologists think they've found some glacial deposits in the form ...

As glaciers retreat due to a rise in global temperatures, one study shows that detailed 3D elevation models could drastically ...

The cool conditions which have allowed ice caps to form on Earth are rare events in the planet’s history and require many complex processes working at once, according to new research. A team of ...

Ice sheets once covered much of the Northern Hemisphere during the ice age. Now, Earth has just two ice sheets: one covers most of Greenland, the largest island in the world, and the other spans ...

Even the balmy tropics may have once been crushed by colossal masses of ice. A severe ice age dominated Earth, some 720 to 635 million years ago, well before dinosaurs stalked the land. But it's ...

Anyone living on Earth between 720 million and 635 million years ago probably would've needed a jacket. Geologists have long suspected that Earth's temperature dropped dramatically during this ...

Geologists have long suspected that Earth's temperature dropped dramatically during this time, resulting in a frigid "Snowball Earth."But they've argued quite a bit about just how icy the planet ...
