A massive iceberg the size of Delaware is now even closer to breaking free from Antarctica, due to a widening crack in the ice shelf, scientists report. The Larsen C Ice Shelf in Antarctica is cut through by a growing rift, which stretches nearly 109 miles (175 kilometers) long, new satellite data has revealed. Already in 2017, the rift has grown by 6.2 miles (10 km), and now only 12.4 miles (20 km) of ice are anchoring the massive iceberg to the ice shelf, according to Project MIDAS, an Antarctic research project based in the United Kingdom.
