Antarctic rift grows 17 km in 6 days, iceberg nears breakage

A rift in Antarctica's Larsen C ice shelf has grown by 17 km in six days, leaving it only 13 km far from producing the biggest iceberg ever recorded, UK-based researchers recently found. Possible separation of the 5,000-square-km iceberg would leave the 350-metre thick shelf vulnerable to future break-up, scientists said, who denied linking the event to climate change.
