 On September 14, 2007 the European Space Agency reported ice loss had opened up the Northwest Passage "for the first time since records began in 1978", and the extreme loss in 2007 rendered the passage "fully navigable".Further exploration for petroleum reserves elsewhere in the Arctic may now become more feasible, and the passage may become a regular channel of international shipping and commerce if Canada is not able to enforce its claim to it.Foreign Ministers and other officials representing Canada, Denmark, Norway, Russia, and the United States met in Ilulissat, Greenland in May 2008, at the Arctic Ocean Conference and announced the Ilulissat Declaration.
