I knew icebergs could be big, but this really takes the biscuit. The end of the Pine Island Glacier in Antarctica has broken off to form an iceberg larger than central London.
This monstrous lump of ice has an area of 720 square kilometres. The Pine Island Glacier is the fastest shrinking in the world and the icebergs it spawns contribute to rising sea levels.
The berg will soon move out into the Southern Ocean. I'll be sure to avoid sailing on any cruise ships in the area until it's melted!
