Bowhead whale migration in Alaska is two months late, according to Inside Climate News.

Usually in October, the bowhead whales make their annual migration. Roughly 17,000 whales depart from northern Canada and travel west, along the northern shores of Alaska, before crossing the Chukchi Sea to Russia.

In Utqiagvik, where 63 percent of the population is Iñupiat Iñupiaq, many people rely on food they hunt and catch, and they count on the fall whale hunt to fill their ice cellars for the winter.

Neither the local population nor scientists have ever seen anything like this, with whales simply not arriving at such a crucial point of time. It is believed that climate changes have changed the Bering Sea ecosystem and that this has also affected the whales and their migration habits.
