 Other studies show that between 1960 and 1999 , the Devon Ice Cap lost 67 km3 ( 16 cu mi ) of ice , mainly through thinning . All major outlet glaciers along the eastern Devon Ice Cap margin have retreated from 1 km ( 0 @.@ 62 mi ) to 3 km ( 1 @.@ 9 mi ) since 1960 . On the Hazen Plateau of Ellesmere Island , the Simmon Ice Cap has lost 47 % of its area since 1959 . If the current climatic conditions continue , the remaining glacial ice on the Hazen Plateau will be gone around 2050 . On August 13 , 2005 , the <unk> Ice Shelf broke free from the north coast of Ellesmere Island . The 66 km2 ( 25 sq mi ) ice shelf drifted into the Arctic Ocean . This followed the splitting of the Ward Hunt Ice Shelf in 2002 . The Ward Hunt has lost 90 % of its area in the last century .
