Scientists at the University of California, Berkeley, and Boise State University have found evidence suggesting that the Marinoan glaciation began approximately 639 million years ago and lasted for ...

Southeastern Tibet is one of the most glaciated regions on the Tibetan Plateau both at present and during the Quaternary. Numerical dating of glacial deposits has allowed the establishment of a ...

In recent years global warming has left its mark on the Antarctic ice sheets. The 'eternal' ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East ...

During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have been described as either "Snowball" and "Slushball" Earth scenarios. In ...

Glaciers reached Cape Cod, Massachusetts, in the most recent ice age about 20,000 years ago. But much harsher ice ages hit the Earth in an ancient geological interval known as “the Cryogenian Period” ...

Earth has gone through many geologic phases, but it did have one striking period of stasis: Our planet experienced a tropical environment where algae and single-celled organisms flourished for almost ...

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 ...

For 56 million years, Earth appears to have lurched between two extremes that are hard to picture together: a planet sealed in global ice, then a world hot enough to strip carbon dioxide from the sky ...

Throughout its approximately 4.54 billion-year history, Earth has undergone several ice ages ranging from relatively mild to extreme. Researchers believe our planet has endured five ice ages belonging ...

The Himalayan range hosts the largest concentration of non-polar glaciers, whose advances and retreats since the onset of the Quaternary have been shaped by a complex interplay between monsoonal ...

Vast amounts of sediment eroded from Earth’s continents were necessary to lubricate the wheel of plate tectonics, scientists propose. The idea offers a new angle on long-standing riddles about the ...
