COLD CASE: Breakup of Pine Island Glacier (VIDEO)
Caption
In 2015, a 225-square-mile iceberg broke off of the Pine Island Glacier in Antarctica, and researchers at The Ohio State University have discovered that the event was no ordinary breakup. The culprit: a deep subsurface rift that cracked through the ice nearly 20 miles inland -- a sign that the largest ice reserve in the world may be melting sooner rather than later.
