Some of the ice may remain in the area for decades, while parts of the iceberg may drift north into warmer waters."Įditor's Note: This article was updated to clarify when the rift in the ice sheet first showed up. The 1,667-square-mile block of ice is more than three times the size of Los Angeles. "It may remain in one piece, but is more likely to break into fragments. The world’s largest iceberg has broken off from Antarctica, the European Space Agency reported. The visible cliffs on these icebergs rise above the waterline by tens of metres, which means the ice extends down from the water surface by. "The iceberg is one of the largest recorded and its future progress is difficult to predict," Adrian Luckman of Swansea University, lead investigator of the MIDAS project, said in the statement. A81 broke away from the Brunt Ice Shelf in January. We're going to be watching very carefully for signs that the rest of the shelf is becoming unstable."Īs for what will happen to this huge chunk of ice, nobody knows at the moment. "This is the furthest back that the ice front has been in recorded history. "Although this is a natural event, and we're not aware of any link to human-induced climate change, this puts the ice shelf in a very vulnerable position," Martin O’Leary, a Swansea University glaciologist and member of the MIDAS project team, said in a statement. This animation shows the giant slab of ice breaking off from the Ronne Ice Shelf, lying in the Weddell Sea, on May 13. And it's this once-land-based ice that would impact sea levels, researchers say. The world’s largest iceberg, dubbed A-76, has calved from Antarctica. A more than 600-square-mile iceberg broke off Antarctica in recent days, but the event is part of a normal cycle and is not related to climate change, scientists say.
