Scientists say a giant iceberg is ready to break away from Antarctica

Scientists say an iceberg is ready to break away from Antarctica. This happens all the time but this is a big one - possibly the biggest on record at 3,000 square miles or a quarter the size of Wales.

Professor David Vaughan, glaciologist and the director of science at the British Antarctic Survey, describes the process of it "breaking away" to the Today programme.

He says penguins and seals won't be affected, in fact sometimes they even hitch a ride as icebergs glide through the water.
