"An iceberg twice the size of New York City is about to break off of Antarctica's Brunt Ice Shelf, according to NASA.

"Cracking across Antarctica’s Brunt Ice Shelf is set to release an iceberg w/ an area about 2x the size of NYC. The splitting could result in an uncertain future for the shelf’s scientific research & human presence," NASA said in a tweet.

NASA said in a statement that there are cracks growing across the ice shelf that were first observed in October 2016. It's not clear how the ice shelf will fare following the iceberg break, according to NASA."
