A giant iceberg, with an area equivalent to Liguria (a region in Italy), is poised to break off from the Antartica shelf.
A thread of just 20km of ice is now preventing the 5,000 sq
km mass from floating away, following the sudden expansion last month of a rift
that has been steadily growing for more than a decade.
The iceberg, which is positioned on the most northern major
ice shelf in Antarctica, known as Larsen C, is predicted to be one of the
largest 10 break-offs ever recorded.
