7-Square-Mile Ice Sheet Breaks Loose in Canada

A seven mile long Canadian ice sheet has broken off an ice shelf in the Arctic, which is the largest piece shed by one of Canada's ice shelves since the Ayles shelf broke loose in 2005 from the coast of Ellesmere. Ice shelves, formed by snow and freezing water, are large platforms of thick, ancient sea ice that float on the ocean's surface. Research suggests that the current Arctic climate isn't rebuilding ice sheets. In fact, the ice has not formed in the past two years. Global warming is progressing at a more alarming rate than predicted. If the trend continues, Arctic sea ice may be gone forever. – YaleGlobal
