    A trillion tonne iceberg, one of the largest ever recorded, has snapped off the West Antarctic ice shelf, scientists who have monitored the growing crack for years reported. The calving occurred sometime between July 10 and July 12 when a 5,800-square kilometre (2,200 square mile) section of Larsen C ice shelf finally broke away.
    The massive ice cube, larger than the US state of Delaware, has a volume twice that of Lake Erie, one of the Great Lakes. It is about 350 metres (1,100 feet) thick.
    The iceberg weighs more than a trillion tonnes, but it was already floating before it calved away so has no immediate impact on sea level. It will likely be named A68.
    Icebergs calving from Antarctica are a regular occurrence. But given its enormous size, the latest berg will be closely watched as it travels, for any potential risk to shipping traffic.
