Iceberg the size of Delaware to break off of Antarctica

A large sheet of ice is set to break away from Antarctica and scientists say it will be one of the largest breaks of its kind recorded. Larsen C, a sprawling sheet of ice in western Antarctica, is currently attached to its parent shelf by 20 kilometers (12.4 miles) of ice. Once it splits, the crack will produce an iceberg around 5,000 square kilometers (1,930 square miles) which is approximately the size of the state of Delaware.
