Iceberg twice size of Luxembourg breaks off Antarctic ice shelf

Satellite data confirms 'calving' of trillion-tonne, 5,800 sq km iceberg from the Larsen C ice shelf, dramatically altering the landscape

A giant iceberg twice the size of Luxembourg has broken off an ice shelf on the Antarctic peninsula and is now adrift in the Weddell Sea.

Reported to be "hanging by a thread" last month, the trillion-tonne iceberg was found to have split off from the Larsen C segment of the Larsen ice shelf on Wednesday morning after scientists examined the latest satellite data from the area.
