If they break apart more letters are added to differentiate the fragments. Icebergs are traditionally named after the Antarctic quadrant in which they were originally detected, then a sequential number. Hydrofracturing occurs when water –which is heavier than ice – pours through cracks in the surface of ice shelves caused by surface warming, violently forcing the fractures to zip open, causing an iceberg to break off. This was followed by the breakup of the nearby Wilkins Ice Shelf in 20.Ī process known as hydrofracturing was likely the main culprit in both cases, earlier research has shown. Major chunks of the Peninsula's Larsen Ice Shelf - which had been stable for more than 10,000 years – disintegrated within days in 1995, and again in 2002. The iceberg, known as A68a, had also broken off from the Larsen Ice Shelf, which has warmed faster than any other part of Earth's southernmost continent.Ī68a, which was 160 kilometres long and 48 kilometres across, broke apart before it could cause any damage to the abundant wildlife in the British Overseas Territory of South Georgia.Įarth's average surface temperature has gone up by one degree Celsius since the 19th century, enough to increase the intensity of droughts, heatwaves and tropical cyclones.īut the air over Antarctica has warmed more than twice that much.
