The crack in this Antarctic ice shelf just grew by 11 miles. A dramatic break could be imminent.
An enormous rift in one of Antarctica’s largest ice shelves grew dramatically over the past month, and a chunk nearly the size of Delaware could break away as soon as later this winter, British scientists reported this week.

If this happens, it could accelerate a further breakup of the ice shelf, essentially removing a massive cork of ice that keeps some of Antarctica’s glaciers from flowing into the ocean. The long term result, scientists project, could be to noticeably raise global sea levels by 10 centimeters, or almost four inches.

It’s the latest sign of major ice loss in the fast warming Antarctic Peninsula, which has already seen the breakup of two other shelves in the same region, events that have been widely attributed to climate change.

The crack in the ice shelf, known as Larsen C, has been growing at an accelerating rate. Since the beginning of December, it has grown about 11 miles in length, after extending 13 miles earlier in the year. In total, the rift has grown about 50 miles since 2011 (it’s almost 100 miles long in total), and has widened to well over 1,000 feet. Now, only 12 miles of ice continue to connect the chunk with the rest of the ice shelf.
