The findings, published Thursday in the journal Science, suggest that the Cordilleran ice sheet had largely melted as early as 14,000 years ago, a revision of previous estimates that much of western ...

They then supposedly traveled south through an ice-free corridor between the Laurentide and Cordilleran ice sheets that opened approximately 13,000-14,000 years ago. However, if humans were in New ...

While the Statue of Liberty may not be submerged, low-lying places like Ellis Island could be underwater. By 2100, sea-level ...

A new study found parts of Antartica could pass a tipping point for mass ice sheet losses as soon as 2050 – pushing sea ...

Microbial communities feeding on geothermal methane seeps beneath the Antarctic ice sheet could resemble life-supporting ...

During cold (glacial) cycles, ice sheets sprawled across Antarctica, Greenland and North America, locking away water and lowering sea levels. In warmer (interglacial) times, the ice retreated and ...

Scientists at Little Dome C recovered the oldest continuous ice core, unlocking 1.2 million years of Earth’s climate history.

A vast network of lakes and streams lies beneath the thick ice sheet. This water can lubricate the ice, allowing it to slide more rapidly toward the ocean. Including the effects of evolving ...
