Global warming will remake the map of global shipping, and deal Russia a blow in the process.

This image, published by the Proceedings of the National Academy of Sciences (via Fortune), shows a computer model of what "Supra-Polar" shipping routes will look like if global warming proceeds as expected. As you can see, a melting Arctic will open up a vast swath of ocean, including the Northwest Passage, which is expected to shave 30 percent of the distance to and from North America compared to the current Northern Sea Route, which hugs the Russian coastline.

By mid-century, the shortest route to travel from the Atlantic to the Pacific will be the North Pole.

The melting ice not only introduces unpredictable environmental variables, it also deals a blow to Russia's strategic position. As Jennifer Abbasi notes, Russia charges fees for vessels operating in its exclusive economic zone. As the ice opens up and more vessels can range beyond Russia's territorial waters, they'll lose out on their cut.
