The most positive thing that US National Snow and Ice Data Center sea ice experts could say about this year’s winter sea ice maximum was that it wasn’t a record breaker. But it provides ample polar bear habitat when the bears need it most: just before the critical spring feeding season.
In fact, they said: “The 2020 maximum sea ice extent is the eleventh lowest in the 42-year satellite record, but the highest since 2013.” All that winter ice is essential polar bear habitat just before the critical spring feeding season (Crockford 2019, 2020) and it’s one of the reasons that polar bears are thriving.
On this first anniversary of the publication of The Polar Bear Catastrophe That Never Happened, it’s a day of celebration for me. The book has informed thousands about how and why the scary stories about the imminent demise of polar bears due to human-caused global warming failed so miserably. It is a story of the triumph of facts over assumptions and a perfect example of why scientific observations trump model predictions. It is also a study of science at its worst: how a close-knit community of scientists groomed by a few senior researchers was able to cast out an insider who refused to tow the line on their climate change agenda – and mobilized mobs to attack outsiders who questioned their authority.
If you haven’t read it, now may be the perfect time. Many of you will be forced or encouraged to stay at home because of Covid-19 concerns, so here is one way to put the time to good use. Ebooks are perfect for this situation. If you don’t like Amazon, Smashwords has an ebook version here.
Smashwords also has an ebook version of my novel, EATEN. This polar bear attack thriller is a timely read for a number of reasons but primarily because it’s the story of an animal epidemic with horrific consequences quite different from the one we are facing at the moment.
My polar bear science book for kids, Polar Bear Facts and Myths in ebook form might be the perfect diversion for kids at home who need interesting educational material.
You’ll find links to all of my books, in all countries and all outlets, at my personal website here.

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.
