On February 24th, NASA tweeted that the giant cracks in the Brunt Ice Shelf could be about to release an iceberg twice the size of New York City. The crack was stable for 35 years but has been opening at an ever faster rate since 2012.

The calving such a giant iceberg could have a major impact, not least on the scientific research that’s carried out in this part of Antarctica.
