World’s largest iceberg about to crash into remote island owned by Britain
The world’s largest iceberg - roughly the size of Cornwall - is about to crash into a remote British island, putting the lives of penguins and seals in danger. A23 is one of the world's oldest icebergs and once measured 3,900 sq km. However, recent satellite pictures have revealed that it is decaying and is now around 3,500 sq km.
