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 ...

P arts of the ocean reached temperatures of -15°C (5°F) without freezing 717-660 million years ago, geologists and ...

Between 640 and 720 million years ago, the Earth was covered in ice, snagging it the modern nickname “Snowball Earth.” Recently, researchers found a rock formation that shows the transition from a ...

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, ...

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 ...

A Yale-led research team has picked a side in the “Snowball Earth” debate over the possible cause of planet-wide deep freeze events that occurred in the distant past. According to a new study, these ...

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 ...
