Iceberg four times the size of Manhattan breaks off Antarctica
An iceberg four times the size of Manhattan, 100-square-mile (259 km²), just broke off from Antarctica’s Pine Island Glacier. A worrying 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 km²).
