Scientists have been monitoring the crack in Larsen C for several years, but the rift experienced a major growth spurt this past December when it lengthened by 12 miles (20 km). The 300-foot-wide crack advanced an additional six miles (10 km) in January, and earlier this month a second crack appeared at the leading edge. It’s the tip of this second crack that’s now headed straight for the ocean.
Collapse of Enormous Antarctic Ice Shelf Imminent
In a dramatic development, the giant rift in the Larsen C ice shelf has grown an additional 11 miles (17 km) since last week, and the leading tip of the crack is now exceptionally close to the ocean. There’s now very little to prevent a complete collapse—an event that will produce one of the largest icebergs in recorded history.
