Ships to sail directly over the north pole by 2050, scientists say

(B)y 2050, say Laurence C. Smith and Scott R. Stephenson at the University of California in the journal PNAS on Monday, ordinary vessels should be able to travel easily along the northern sea route, and moderately ice-strengthened ships should be able to take the shortest possible route between the Pacific and Atlantic Oceans, passing over the pole itself. The easiest time would be in September, when annual sea ice cover in the Arctic Ocean is at its lowest extent.
“The prospect of common open water ships, which comprise the vast majority of the global fleet, entering the Arctic Ocean in late summer, and even its remote central basin by moderately ice-strengthened vessels heightens the urgency for a mandatory International Maritime Organisation regulatory framework to ensure adequate environmental protections, vessel safety standards, and search-and-rescue capability,” it adds.
