Arctic Sea Space: Trans-Arctic Shipping "By MidCentury"

From the Proceedings of the National Academy of Sciences of the U.S., "New Trans-Arctic shipping routes navigable by midcentury":

By midcentury, changing sea ice conditions enable expanded September navigability for common open-water ships crossing the Arctic along the Northern Sea Route over the Russian Federation, robust new routes for moderately ice-strengthened (Polar Class 6) ships over the North Pole, and new routes through the Northwest Passage for both vessel classes. Although numerous other nonclimatic factors also limit Arctic shipping potential, these findings have important economic, strategic, environmental, and governance implications for the region.

Of course they do.

We need a bigger presence in our Arctic Waters including Coast Guard and a U.S. Navy "Northern Fleet."
