Like the glaciers that feed them, ice shelves are immense. Yet the ocean processes that control basal melting, and the fate of the entire Antarctic ice sheet, occur on the scale of millimetres.

Instead, polar scientists created a definition for an ice-free Arctic as when less than 1 million square kilometers (0.39 million square miles) of ice can be found within the Arctic Ocean.
