The last remaining section of Antarctica’s Larsen B Ice Shelf — which serves as a barrier to keep glaciers from melting into the ocean — is rapidly disintegrating and expected to disappear by 2020, according to a new NASA study. Ice shelves naturally shed icebergs, and this ice shelf could recover and avoid the fate of Larsens A and B. Alex Brisbourne et al.
