After a bit of ineffectual hand-wringing from polar bear specialists about low summer and fall sea ice conditions and unsubstantiated worries about impacts on bear survival – including Southern Beaufort Sea, Chukchi Sea and Hudson Bay – I’ve heard no concerns expressed so far about the unusually low extent of ice off the East Coast of North America at the start of this winter. The Labrador Coast is just about the only region bereft of ice this winter but could catch up quickly at any time: ice coverage in the Barents Sea, East Greenland, and Bering Sea is similar to or above recent levels (last five years) so far, as is the overall extent.

Fancy that! After a load of handwringing earlier this month, mobile pack ice in the Bering Sea has returned. Just like ice in the Barents Sea, Bering Sea ice is highly variable (Brown et al. 2011): it moves with winds and currents, so a ‘decline’ during the winter usually indicates redistribution, not melting.

According to researcher Rick Thoman from the University of Alaska Fairbanks, quoted by the Canadian Press:
“Wind blew ice to Russian beaches in the west and to the south side of Norton Sound south of Nome but left open water all the way to Chukchi Sea north of the Bering Strait.”
Polar bears that venture into the Bering Sea are part of the Chukchi Sea subpopulation, which is known to be thriving (Crockford 2019; AC SWG 2018; Regehr et al. 2018; Rode and Regehr 2010; Rode et al. 2013, 2014, 2015, 2018).

From CBC News late yesterday (28 February 2019) comes the news that a polar bear seen skulking around the homes of a small coastal town in Labrador this week has had residents on edge and authorities on high alert. If tragedy struck, the St. Lewis road was blocked by snow and the only way in or out was by helicopter. Message: polar bears are highly dangerous and a bear prowling a community is a very real threat to safety.

According to a CTV News follow-up, while the road to St. Lewis was cut off because of a recent snowstorm for most of the week, wildlife officers were able to get in today (Friday 1 March). Sighting about 100km north in Charlottetown earlier in the week are believed to be the same bear.
The last sighting of the animal was Thursday morning (28 Feb), so the bear may now have left of its own accord. No one seems to have captured a photo.
However, the fear felt by residents of St. Lewis (population 200) in this story is palpable, especially after the terrifying visuals from the well-publicized invasion by more than 50 polar bears at Belushaya Guba on Novaya Zemlya last month.
St. Lewis is located at the red marker; Charlottetown is the third town to the north. Both are just north of the Strait of Belle Isle that separates Labrador from the island of Newfoundland.

According to a report by CBC News earlier this week (18 February 2019), there was a defence kill of a potentially dangerous polar bear and her cub in Foxe Basin, Nunavut on January 4th that we are just hearing about now. Yet another bear on shore in winter, when there is plenty of sea ice, looking for food in an Arctic community and threatening the lives of its residents while a polar bear specialist blames such incidents on lack of ice.

January is the first month of the Arctic winter, the season when most polar bears really struggle to find enough to eat.
Here is what the sea ice looked like around the Arctic at the end of this month.

A man from Arctic Village (Alaska), out checking his trap-line, killed a polar bear at his cabin when it came after him: only odd things were it was the first week of January and the cabin was more than 100 miles south of the Beaufort Sea coast.
Winter is hard for polar bears, as I’ve mentioned before: it’s cold, dark, and hard to find seals. Most bears are at their lightest weight at the end of winter (March). Looking for food in the dead of winter, the bears can be very destructive as well as dangerous. See previous posts here, here, here, and here.
The map below shows how far south Arctic Village is from the Beaufort coast. This hunter is lucky he had his wits about him and his gun handy, because he came awfully close to being a polar bear’s dinner.
Here’s an excerpt of the story (my bold): “Polar bear encounter reported in Arctic Village, many miles south of normal range” (KTOO, Ravenna Koenig, 15 January 2019):
