Latest satellite images reveal a new 100-square-mile iceberg emerging from Antarctica's Pine Island Glacier. The calving event did not come as a complete surprise, but is a troubling sign with regards to future sea level rise.

Pine Island Glacier (PIG) is the fastest melting glacier in Antarctica — one that's responsible for a quarter of the frozen continent's ice loss, around 45 billion tons of ice each year. Satellite images taken on 26 September show an open-water gap emerging between the ice shelf and the iceberg, which is about two thirds the size of the Isle of Wight (103 square miles or 267 square km).
