Russian tanker passes through Bering Strait in the midst of winter

Last week, a 908-foot Russian tanker carrying liquified natural gas passed south through the Russian side of the Bering Strait, with two more to follow. The ships are traversing the northern coast of Siberia, called the North Sea Route, in the middle of January with no icebreaker escort, an unprecedented event that may hint at the future of the region as climate change alters global commerce.
