Researchers use 1,000 historical photos to reconstruct Antarctic glaciers before a dramatic collapse
In March 2002, the Larsen B Ice Shelf collapsed catastrophically, breaking up an area about one-sixth the size of Tasmania.

Ice is believed to have played a crucial role in the emergence of life. One reason is that organic molecules can be excluded into the gaps between the crystal lattice by orderly arranged water molecules, leading to the concentration ...

Slush—water-soaked snow—makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models.

A new and worrying way that large ice sheets can melt has been characterized by scientists for the first time. The research focuses on how relatively warm seawater can lap at the underside of ground-based ice, which can accelerate ...
