One of the biggest icebergs2 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.
 
有记录在案的最大冰山之一,七倍于纽约城大小、一万亿吨的巨大怪兽,已从南极洲断裂,引发了科学家们关于全球变暖是否主因的争论。
 
 
The event, captured by satellite, happened sometime in the past few days when the giant chunk3 snapped off an ice shelf.
 
While such "calving" of icebergs is not unusual, this is an especially big one. It covers an area of roughly 2,300 square miles (6,000 square kilometers), more than twice the size of Luxembourg. Its volume is twice that of Lake Erie, according to Project MIDAS, a research group based in Britain.
 
It broke loose from the Larsen C ice shelf, which scientists had been monitoring for months as they watched a crack grow more than 120 miles (200 kilometers) long.
 
Scientists say global warming has caused a thinning of such shelves, but they differ on whether the latest event can be blamed on climate change.
 
The iceberg1 is considered unlikely to pose any threat to shipping4. And since the ice was already floating, the breakup won't raise sea levels in the short term, the project said in a statement.
 
But it removed more than 10 percent of the ice shelf, and if that eventually hastens the flow of glaciers5 behind it into the water, there could be a "very modest" rise in sea level, the project said.
