A sea in Russia’s Arctic known as the “birthplace of ice” could break ice melt records for a second consecutive year in 2021, climatologist Zachary Labe of Colorado State University tweeted Tuesday. In 2020 the Laptev Sea stayed ice-free until November for the first time in documented history. The sea, which plays a crucial role …

These ice platforms are the floating protrusions of glaciers flowing off the land, and ring the entire continent. The European …

It’s also filled top to bottom with ice, which US space agency (Nasa) scientists reveal in a new report has …

The images are murky at first. Sediment sweeps past the camera as Icefin, a bright yellow remotely operated robot submarine, moves tentatively forward under the ice. Then the waters begin to clear. Icefin is under almost half a mile (600m) of ice, at the front of one the fastest-changing large glaciers in the world. Suddenly …

The massive ice sheet covering Greenland may have melted by a record amount this year, scientists have warned. During this year alone, it lost enough ice to raise the average global sea level by more than a millimetre, possibly even more. Researchers say they’re “astounded” by the acceleration in melting and fear for the future …

The stunning picture may seem typical enough of the Danish territory. What’s beneath their feet …

Rapidly melting sea ice in Greenland has presented an unusual hazard for research teams retrieving their oceanographic moorings and weather station equipment. A photo, taken by Steffen Olsen from the Centre for Ocean and Ice at the Danish Meteorological Institute on 13 June, showed sled dogs wading through water ankle-deep on top of a melting …
