(Luke Copland via AP) Much of Canada’s remaining intact ice shelf has broken apart into hulking iceberg islands thanks to a hot summer and global warming, scientists said. Located on the northern margin of Canada’s Ellesmere Island, the ice platform split on 30/31 July to form a free-floating bloc some 80 sq km (30 sq miles) in area. Scientists have long expected that shrinking Arctic sea ice cover will lead to strong warming of the Arctic air. A huge chunk larger than Manhattan, roughly 43% of the shelf, broke off in one piece. These are big pieces of ice,” said Luke Copland, a glaciologist at the University of Ottawa who was part of the research team studying the Milne Ice Shelf. This has increased concerns over the rapid melting of ice and the breaking of old ice shelfs — large floating pieces of ice that form when a glacier or ice sheet flows into the sea surface. Her work on climate change in the Arctic has also been featured on the TV science program Découverte, as well as Le Téléjournal, the French-Language CBC’s flagship news cast. Ice shelves in the Arctic are created by snow accumulating at the top of glaciers, while at the bottom, ice combines with multi-year land fast ice.
