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" ...

Research on the Quaternary glaciation of the Iberian Peninsula reveals a complex record of glacial advances and retreats interwoven with episodes of rapid climate change. Detailed geomorphological and ...

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 ...

Over 700 million years ago, Earth experienced a dramatic climate event known as the Sturtian glaciation, one of the most extreme ice ages in history. During this period, the planet was encased in ice ...

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 ...

Factory pollution is changing the weather—but not in the way you might think. The tiny aerosol pollution particles poured out by industrial factories can trigger ice to form in the atmosphere, ...

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 ...

(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 ...

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 ...
