Scientists at the University of Southampton have uncovered evidence from ancient rocks that Earth's climate continued to ...

About 700 million years ago, Earth was entombed in a veneer of ice hundreds of feet thick—a frozen state scientists refer to ...

The study suggested that ocean temperatures at continental margins — the areas where life was most active — were ...

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 ...

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 time, ...

Ancient glaciers reshaped Earth’s surface and shifted ocean chemistry, fueling the rise of complex life, a new study found. Calved icebergs from the Twin Glaciers are seen in 2013 off Greenland's ...

(CNN) — More than half a billion years ago on a frigid, ice-covered Earth, glaciers stirred up ingredients for complex life by bulldozing land minerals and then depositing them in the ocean, according ...

Around 700 million years ago, the Earth cooled so much that scientists believe massive ice sheets encased the entire planet like a giant snowball. This global deep freeze, known as Snowball Earth, ...

Around 700 million years ago, Earth was a frozen, white sphere, its rocky surface buried kilometers under ice. Despite the barren landscape, the evolution of complex life in the oceans was about to ...

Planet Earth used to be something like a cross between a deep freeze and a car crusher. During vast stretches of the planet’s history, oceans from pole to pole were covered with a blanket of ice a ...
