According to a new study, something as small as a light icebreaker could go in the Arctic Ocean by the middle of the century, including straight over the North Pole, thanks to the ongoing effects of climate change. [NBC]
Ordinary vessels, which account for more than 99 percent of shipping traffic, could easily navigate the Northern Sea Route along the Russian coastline and, in some years, even find a route through the fabled Northwest Passage… the temptation is likely to prove irresistible to some shipping companies and adventurous tourists, which opens up new concerns about search and rescue infrastructure, the environmental impact from increased shipping traffic and the potential for oil spills, among other issues.
[Laurence C. Smith, a geographer and sea ice expert at the University of California, Los Angeles] and graduate student Scott Stephenson used the output of climate models to chart the fastest, most efficient, and realistic routes through the Arctic for different classes of ships that will become possible as more sea ice disappears each summer.[...]
The new findings, published today in the Proceedings of the National Academy of Sciences, indicate shipping companies willing to invest in light icebreaker technology, known as Polar Class 6 vessels, can avoid those fees by going over the North Pole or through the Northwest Passage.
Regular ships, too, will be able to navigate at least some of these routes unescorted. And, “it doesn’t matter whether we get serious about curbing the growth of greenhouse gas emissions or not,” Smith said. “Either way, the result is the same. The ice will thin sufficiently.”
