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 ...

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 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 ...

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 ...

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 ...

At least twice in Earth’s history, beginning an estimated 700 million years ago, our planet was engulfed in snow and ice in quick succession. But now Two MIT scientists suggest that these events were ...

When ice possibly swathed the entire world, the oceans underneath may have nevertheless surprisingly churned, potentially helping to provide life with vital nutrients, new research suggests. For ...

Scientists think that Earth turned into a "snowball" at least twice in quick succession around 700 million years ago due to significant and rapid drops in the amount of solar radiation reaching the ...

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 ...

Over its relatively young 4.54 billion years of existence, Earth has been host to a number of awe-inducing geological phenomena and climate changes, including the time it turned into a massive ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Scientists at the University of Southampton have discovered that ...
