The world's largest iceberg — which is roughly the size of Rhode Island — is fast approaching a remote British Island and wildlife haven in the South Atlantic.
As of Jan. 16, the megaberg, known as A23a, is roughly 180 miles (290 kilometers) away from South Georgia and the South Sandwich Islands, according to location coordinates from the U.S. National Ice Center. A collision with these islands could be catastrophic for the large colonies of penguins, seals, and other wildlife that live there.
