Melting glaciers and ice caps on Canadian Arctic islands play a far greater role in sea level rise that previously suspected. Between 2004 and 2009, the 30,000 snow-and-ice covered islands in the Canadian Archipelago shed 363 cubic kilometres (87 cubic miles) of water, equivalent to three-quarters of contents of Lake Erie, the study found. During the first half of this six-year period, the average loss was 29 cubic kilometres (seven cubic miles) per year. But during the second three-year period, the average jumped to 92 cubic kilometres (22 cubic miles) annually.
Over the full six years, this added a total of one millimeter to the height of the worlds oceans, the researchers calculated.
