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" ...

Orbit can pace ice ages, but modern CO2 shifts the clock. The next true glacial era is far off, while warming runs hot right ...

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 ...

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 ...

Caribou (known as reindeer in Europe) make one of the longest seasonal migrations of land animals, but an individual's propensity to migrate depends on its genetic ancestry, researchers report.

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 ...

Australian geologists have used plate tectonic modeling to determine what most likely caused an extreme ice-age climate in Earth's history, more than 700 million years ago. The study, published in ...
