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 ...

An ice shelf the size of New York City has collapsed in East Antarctica, an area long thought to be stable and not hit much by climate change, concerned scientists said Friday. The collapse, captured ...

Berry Glacier, a tributary of the Getz Ice Shelf in West Antarctica, has deteriorated dramatically in the past three decades, ...

This study gives important information that helps predict how Antarctica’s ice sheets might change in the future.

The Ross Ice Shelf appears to be melting in previously unknown ways. This is an Inside Science story. Most of the worry over melting ice in Antarctica has focused on the rapidly melting western shore, ...
