A partial breakup of the Larsen C ice shelf is imminent, scientists say, resulting in one of the largest icebergs on record—roughly the size of Delaware.
Researchers who closely monitor a crack cutting across the floating Antarctic ice shelf reported on Thursday that its progress had suddenly sped up, indicating that a collapse may soon be underway. If and when it occurs, it could yield one of the top ten largest icebergs on record, possibly in the top three.
More worrisome is the possibility that the calving event—which refers to the breaking off of the iceberg, from the ice shelf that it’s now attached to—could speed up the disintegration of the broader ice shelf and land-based ice that lies behind it. Read more…
