Massive Antarctic Ice Shelf Faces Imminent Risk of Collapse

An Antarctic ice shelf that is twice the size of Hawaii is at “imminent risk” of collapse and needs to be monitored carefully, a new study finds. The ice shelf—Larsen C—is located in roughly the same geography as the Larsen A and B ice shelves, which disintegrated in 1995 and 2002, respectively.
