One of the world's biggest icebergs closer to splitting from Antarctica

A huge ice sheet more than half the size of Qatar could soon break off from Antarctica.

If the Larsen C breaks free, it'll be one of the world's biggest ever icebergs, measuring 6,000 square kilometers or 2,300 square miles.

That's the size of four Londons or more than seven New York Citys.

In early June, scientists said the Larsen C was 13 kilometers (8 miles) from the edge of the ice. It's now just five kilometers (3 miles) away, according to the European Space Agency (ESA).

Larsen C is a portion of the greater Larsen Ice Shelf on the northeastern coast of Antarctica.
