The melting of the ice cap already allows cargo ships to make the journey through the Northwest Passage in the Canadian archipelago for several summer weeks a year, thus cutting at least a week from the transit time from Europe to China. The first cargo ship not to be escorted by an icebreaker went through in 2014. The Nunavik carried 23,000 tons of nickel ore from Canada to China. The polar route was 40 per cent shorter and used deeper waters than if it had gone through the Panama Canal.
