The Arctic's Two Shipping Routes

The gradual melting of sea ice caused by global warming could potentially open up two shipping routes to the east and west of the North Pole. The new routes would shorten trips between the Atlantic and Pacific oceans by several thousand kilometers, saving time and fuel. However, there are still significant obstacles to the regular transit of oil tankers, including seasonal navigability, the scarcity of port infrastructure and, most important, the risks posed by icebergs and shallow passages.
