Glacial Ice Offers Polar Bears a Precarious Climate Refuge
An isolated polar bear population in southeastern Greenland survives in fjords, despite spotty sea ice. But this pocket of bears is not a sign of how the species could be saved.

Underwater Sounds Help Reveal Extent of Glacial Calving
If a glacier calves into the Arctic Ocean, does it make a sound? Some scientists say yes and have devised a clever way to use those sounds to calculate the size of the fallen ice chunks.

Seafloor Reveals a Period of Rapid Retreat for Thwaites Glacier
New high-resolution seafloor imagery shows a series of delicate ridges produced by the glacier’s front as it bobbed daily with the tides, revealing a recent period of rapid retreat.New high-resolution seafloor imagery shows a series of delicate ridges produced by the glacier’s front as it bobbed daily with the tides, revealing a recent period of rapid retreat.

Melting Below the Pine Island Ice Shelf Minds the Gap
New research shows that increased calving from West Antarctica’s Pine Island Ice Shelf will likely drive increased circulation of warm water—and melting—below the ice.
