Cracks are still spreading where that massive Antarctic iceberg broke free

Cracks continue to spread on the Antarctic ice shelf where a trillion-ton iceberg roughly the size of Delaware broke free in July, scientists say. If these new cracks manage to shake loose key, stabilizing parts of the ice shelf, it’s possible that the ice shelf could collapse. That could speed the flow of Antarctic ice to the sea and cause sea levels to rise.On July 12th, 2017, a deep fissure cleaved a 2,500-square-mile iceberg off of the Larsen-C ice shelf in Antarctica.
