Larsen Ice Shelf, Antarctica

These floating ice shelves help to prevent the erosion of the Antarctic ice sheet. Over the last fifty years, scientists have however observed regular collapses of these shelves, along giant cracks that can be several hundred kilometres long and deep. In 2017, a portion measuring more than 6,000 km2, so barely smaller than Corsica, had broken off the Larsen C ice shelf, forming one of the largest tabular icebergs in the world. This disintegration is believed to be due in part to global warming and melting sea ice.
