The Milne Ice Shelf, a fragment of the former Ellesmere Ice Shelf, is located in the Qikiqtaaluk Region, Nunavut, Canada. It is the second largest ice shelf in the Arctic Ocean. Situated on the north-west coast of Ellesmere Island, it is located about 270 km (170 mi) west of Alert, Nunavut. In 1986, the ice shelf had an area of about 290 km2 (110 sq mi), with a central thickness of 100 m (330 ft). Despite being the last ice shelf in the Northern Hemisphere to be fully intact, over 40% of the sheet collapsed within two days at the end of July 2020, a consequence of global warming.
