Giant iceberg to break off from Antarctica
Iceberg the size of the state of Delaware
An iceberg expected to be one of the 10 largest ever recorded is ready to break away from Antarctica, scientists say. A long-running rift in the Larsen C ice shelf grew suddenly in December and now just 20km (12.42 miles) of ice is keeping the 5,000 sq km (1,930 square miles) piece from floating away.
Larsen C is the most northern major ice shelf in Antarctica.
Researchers based in Swansea say the loss of a piece a quarter of the size of Wales will leave the whole shelf vulnerable to future break-up.
