Disaster can come in any shape and size. Recently due to climatic changes and rising global warmingA giant iceberg, with an area equivalent to Trinidad and Tobago, is poised to break off from Antactic 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 Antactica is predicted to be one of the largest 10 break-offs ever recorded.

Professor Adrian Luckman, a scientist at Swansea University said in a statement: “After a few months of steady, incremental advance since the last event, the rift grew suddenly by a further 18km during the second half of December 2016. Only a final 20km of ice now connects an iceberg one quarter the size of Wales to its parent ice shelf.”
