One of the biggest icebergs ever recorded, a trillion-ton behemoth more than seven times the size of New York City, has broken off of Antarctica, triggering disagreement among scientists over whether global warming is to blame.
It was found to have split off from the Larsen C segment of the ice shelf on Wednesday after scientists examined the satellite data from the area, international media reports say. The iceberg is considered unlikely to pose any threat to shipping. And since the ice was already floating, the breakup won’t raise sea levels in the short term, the project said in a statement “The iceberg is one of the largest recorded and its future progress is difficult to predict. It may remain in one piece but is more likely to break into fragments,” Professor Luckman said.
And the British Antarctic survey said there’s not enough information to say whether the calving is an effect of climate change, though there’s good evidence global warming has caused thinning of the ice shelf.
