A crack in the Antarctic ice shelf is only a few miles from forming a giant iceberg

The crack in the Antarctic's Larsen C Ice Shelf is still growing. If the crack extends 12 more miles, a 5,000-square-mile iceberg roughly the size of Delaware will form  in the Weddell Sea.

The iceberg could form at any time, the BBC reported

The looming threat of a full break prevents scientists from setting up a typical camp,  instead forcing them to analyze the crack from the skies.

WATCH | The British Antarctic Survey flew a plane over the ice shelf and captured the growing crack, which is up to 500 meters wide in some places.

Dr. Paul Holland of the BAS said there was "every chance" the ice shelf would remain stable after the crack completed. However, there was a chance it could render the ice shelf unstable. 


While an ice shelf melting does not increase the sea level in itself, it holds back glaciers from flowing into the sea and melting, according to the BAS

The biggest iceberg ever recorded was found in 1956. It was reportedly nearly 20,000 square miles, but there were no satellites at the time to verify that.

In other ice news, a block of ice split from another Antarctic glacier Wednesday. That glacier could potentially raise global sea levels by two feet, The Washington Post reported.

A conservative activist leaked what he claims are secret recordings from inside CNN
