A huge chunk of the Larsen C ice shelf in Antarctica has finally broken off, reports the BBC. A satellite spotted the break on Wednesday, and it probably wasn't difficult: At more than 2,200 square miles, the new iceberg is roughly the size of Delaware.
It's expected to be named A68, reports the Guardian, and its creation isn't a surprise. Scientists have been watching the rift on the ice shelf grow for years, a process that accelerated greatly in recent months. The larger ice shelf is now about 12% smaller, and this tweet from the Project MIDAS research group provides a map.
