The following infographic shows how a general container-ship travel distance would decrease as a result of global warming that opens the Arctic passage.
Until August 24th, 2018, 9.95 million tons of goods went through ports in the region which is an 81% increase compared to last year's 5.5 million.
Though this passage is feasible only for 3 months of the year, global warming is making it advantages for major shipping companies because temperatures this year in the Arctic Circle are unusually warm with a recorded high of topping 30-degree Celsius on several occasions.
Although the travel time can be reduced by two weeks comparing the southern route, overall costs are still higher because the vessels are accompanied by a nuclear-powered icebreaker.
