In a report this week, a team of Canadian and U.S. scientists warned that hungry polar bears are increasingly turning to garbage dumps to fill their stomachs as their icy habitat disappears due to climate change.

A container ship froze into the waters of Yenisei Bay in Russia’s Arctic. Traveling from Dudinka to Arkhangelsk, the ship got stuck in ice on December 13. The crew battled icing, but was not in danger. Three weeks later, the ship was able to break free. According to Atomflot, the ship did not have necessary permissions to sail along this section of the Northern Sea Route.
