Scientists confirmed Wednesday that a much anticipated break at the Larsen C ice shelf in Antarctica has occurred, unleashing a massive iceberg that is more than 2,200 square miles in area and weighs a trillion tons.
In other words, the iceberg — one of the largest in recorded history to splinter off the Antarctic ice sheets — is close to the size of Delaware and consists of almost four times as much ice as the fast melting island of Greenland loses in a year. It is expected to be given the name ‘A68’ soon, scientists said.
“Its volume is twice that of Lake Erie, one of the Great Lakes,” wrote researchers with Project MIDAS, a research group at Swansea and Aberystwyth Universities in Wales that has been monitoring the situation closely by satellite.
The iceberg contains so much mass that if all of it were added anew to the ocean, it would drive almost 3 millimeters of global sea level rise (it takes 360 billion tons of ice to produce 1 millimeter of ocean rise). In this case though, the iceberg is already afloat so there won’t be a substantial sea level change.
