Trillion-tonne iceberg breaks off Antarctica: scientists

A trillion-tonne iceberg, one of the biggest on record, has snapped off the West Antarctic ice shelf, said scientists today who have monitored the growing crack for months.
"The calving occurred sometime between Monday, July 10 and Wednesday, July 12, when a 5,800-square kilometre section of Larsen C (ice shelf) finally broke away," the Swansea University said in a statement.
