Two extreme weather events in 2006 and 2013 caused mass starvation among the reindeer herds, and researchers for the first time have linked these extreme weather events in the coastal mainland in northwest Russia with sea ice loss in the adjoining Barents and Kara seas.

When a storm exposes human remains in Barrow, there isn’t an established protocol. They are usually given to the federally recognized Native Village of Barrow for repatriation.

Yukon subsistence fishermen face challenges with gear restrictions, closures, and reports of salmon potentially infected with ichthyophonus, impacting their summer fishing activities.

Last year, 2014, was the hottest year ever recorded on Earth. Unlike other worldwide problems from which Canadians might feel relatively safe and isolated, but Canada is actually ground zero of global climate.
