Ice lies thick on the water as nuclear powered icebreakers "Sibir" and "Arktika" escort LNG carrier "Fedor Litke" into the Vilkitsky Strait en route to a Northeast Asian port.

Following another year of stark climate impacts in the Arctic, scientists warned Tuesday of a new scourge hitting the region: marine trash. With the region warming twice as fast as the rest of the world, sea ice that has long blanketed the Arctic Ocean is disappearing, opening new routes to shipping.

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.

There has been a surge of plastic trash that has been washing up on beaches in Nome and across the Bering Strait Region.
