The Larsen C ice shelf in Antarctica, from which a Delaware-sized iceberg broke away from two years ago, could be at risk of collapse. Scientists have recorded a spike in late-season surface melt of snow and ice, which they say is being driven by warm, dry wind coming from mountains in the Antarctic Peninsula.

Larsen C is a vast body of ice sitting at the edge of West Antarctica, covering an area of around 17,100 square miles. While its physical breakup would not cause sea levels to rise directly, Larsen C could be a harbinger of things to come for ice shelves further south. Should these larger bodies of ice follow the same path, it could result in sea levels rising by several meters.
