Canada lost an ice sheet seven square miles in area last week. The ice sheet broke off from the Ward Hunt Ice Shelf off of the north coast of Ellesmere Island in Canada's Qikiqtaaluk Region. It was the biggest piece of ice shelf to crack loose since 2005. However, before you panic and start moving back from the coasts in anticipation of rising sea levels, note: Ellesmere Island was once encircled by a single huge ice shelf that broke up in the early 20th century. And according to Derek Mueller, a research at Trent University, the Ward Hunt Ice Shelf has been steadily declining in size since the 1930's. The time scale in question here (as with much of the Earth's warming issues) is geologic.
