Snowpiercer, a graphic novel, movie and TV series, imagines a different deep-freeze scenario: Geoengineering gone haywire. To mitigate global warming, scientists released aerosols into the atmosphere ...

Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago.

There's a billion-year gap in Earth's geological history. A new study seeks to explain the mystery.

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 ...

More than 700 million years ago, our planet experienced a glacial episode of prodigious intensity, to the point that ice sheets extended all the way to the equator, merging together. For the ...

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 ...

Earth froze over 717 million years ago. Ice crept down from the poles to the equator, and the dark subglacial seas suffocated without sunlight to power photosynthesis. Earth became an unrecognizable, ...

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 ...

Imagine a time when the blue planet looked nothing like it does today. A time when the oceans were frozen over, the continents were locked in a thick sheet of ice, and the sun reflected off a world ...

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 ...

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 ...
