Ocean heat, not air temperature, may decide Antarctica’s fate as new models predict widespread ice shelf loss by 2300.

The breakup of the massive Larsen C Ice Shelf in Antarctica is getting closer and will eventually produce an iceberg the size of Delaware prowling the Southern Ocean, according to new NASA data. On ...

"Quicker than we expected." Scientists puzzled by 'whodunnit' scenario unfolding in Antarctica: 'We disagree about the ...

The spectacular disintegration of Antarctica’s “Larsen-B” Ice Shelf was unprecedented since the last ice age, according to a recent study to be published next week in Nature. And the disintegrating ...

A new NASA study finds the last remaining section of Antarctica’s Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and likely to disintegrate completely before the end of ...

Heavy pooling meltwater can fracture ice, potentially leading to ice shelf collapse. When air temperatures in Antarctica rise and glacier ice melts, water can pool on the surface of floating ice ...

A new polar ice study from the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder surfaced groundbreaking evidence of, well … the ground ...

In 2002, NASA released dramatic images that showed a portion of Antarctica's Larsen B ice shelf collapse and disappear. Now, the space agency says what's left of the massive feature will be gone ...

A group of scientists is gathering this week in the U.K. to discuss a slab of ice that's cracking in Antarctica. The crack could soon split off a frozen chunk the size of Delaware. One glacier ...

New Year's Day, 2002. Without warning, a few large cracks in the Larsen B ice shelf appeared in satellite imagery. Within days, car-sized chunks of ice appeared in the water. Then shards of ice larger ...

A familiar philosophical question about trees and forests might be applied to events in the world's loneliest spot: If an ice shelf collapses in Antarctica, and there's nobody around to hear it, does ...

When air temperatures in Antarctica rise and glacier ice melts, water can pool on the surface of floating ice shelves, weighing them down and causing the ice to bend. Now, for the first time in the ...
