Over the weekend in Canada, the CBC ran a polar bear news feature that is now available online (“Polar bears in peril: the bleak future of Churchill bears,” The National, CBC, 3 December 2018). It gave polar bear biologist Nick Lunn of Environment Canada free rein to spread unsubstantiated claims and outright falsehoods about the status of Western Hudson Bay polar bears and sea ice. Apparently, he and the CBC learned nothing from National Geographic‘s fiasco over their ‘starving’ polar bear video last year: they still think the public will be swayed to “act” on human-caused global warming if a persuasive expert tells them that polar bears are on their way to extinction. I expect many were convinced otherwise, since the facts are available for all to see.
No triplet litters born since 1996? Nonsense, as the photo below (from 2017) shows.
The CBC video is described this way:
“They are a majestic icon of Canada’s North, but polar bears have also come to symbolize climate change. And scientists say the future for one particular population of polar bears in northern Manitoba is dire.“

Canadian biologist Andrew Derocher was called upon to promote his particularly pessimistic viewpoint on polar bear survival in a story published in the New York Times yesterday (2 December 2018: “Drilling in the Arctic: Questions for a Polar Bear Expert”). However, decades of evidence suggests that onshore oil exploration in the Arctic National Wildlife Refuge is unlikely to harm the few female bears that come ashore in Alaska to make maternity dens.
Here is my rebuttal to Derocher’s claims, all of which I’ve dealt with previously.

At recent meeting of the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), biologists decided to continue to list the polar bear as a species of ‘Special Concern.’ About 2/3 of the world’s polar bears live in Canada and the balance of all evidence (including Inuit knowledge) indicate the bears are not threatened with extinction. The bears have held this status since 1991.
Details from the 3 December 2018 press release below.
Interesting summary and informed perspective from Nunavut News that’s worth a read on the issue of polar bear management in Nunavut (29 November 2018: “Inuit, Western science far apart on polar bear issues”).
“Nirlungayuk said the predictions made by Western science for the polar bear populations in western Hudson Bay and Baffin Bay were, in a word, wrong.
He said they need to look closely at those predictions and determine how they got them wrong.
“From a scientific perspective, I would challenge the scientific community to take another look at both western Hudson Bay and Baffin Bay to explain why the predictions that were being made back in the early 2000s up to 2018 were so wrong.
“A statement that came from Environment Canada was that the bears will keep on declining because of climate change even without hunting and that hasn’t happened.”

Despite a wild claim that a “slow Arctic freeze” this year increases the risk that polar bears will become extinct, sea ice charts show ice returning earlier than it has for decades everywhere except the Svalbard area of the Barents Sea. That’s good news for pregnant polar bears. Although Svalbard is without ice, that’s been true for so many years that pregnant Svalbard females long ago abandoned the use of islands they used in good ice years and now make their dens in the Franz Josef Land archipelago to the east (which is still within the Barents Sea subpopulation region).
Polar bears give birth around 25 December each year, so pregnant females prefer to be snug in a safe den by around the end of November at the latest. That’s been possible for all regions of the Arctic this year, including the Barents Sea — because sea ice returned to Franz Josef Land weeks ago, even though Svalbard is still ice-free.
Major denning areas in Russia, including Wrangel Island, have been surrounded by ice since the middle of the month, allowing pregnant females that did not remain on shore over the summer to return to make maternity dens. Elsewhere, bears that have been confined to shore over the ice-free season (such as along Hudson Bay and Baffin Island in eastern Canada) returned to the ice to hunt seals weeks ago after the earliest freeze-up in more than two decades.

More ice in Hudson Bay and adjacent regions than we’ve seen at this time of year for more than two decades: not since 1993 has there been as much polar bear habitat in the 2nd-last week of November.
The anomaly chart for this week is almost all blue:
Other years back to 1994 had much less ice for the 2nd-last week in November, as the charts below show. Colour charts are only available from 2004.
Polar Bear Facts and Myths (for children aged 7 and up) is now avaiblable in Norwegian!
The same day as a glowing review of the Dutch translation of my popular children’s science book appeared in de Telegraaf (front page and all of page 5, 19 November 2018, pdf here), I am thrilled to announce that this important book is now available in Norwegian via Amazon worldwide, including European outlets.
The translation was done by native Norwegian speakers Arve Tunstad and Morten Jødal. In Norwegian the book is called ISBJØRN Fakta og Myter.
Please pass along to your friends, relatives, and colleagues in North America and abroad (calling all Sons of Norway). The English version is still available in paperback and ebook formats. Other translations in French and German are already available: five languages in all, including Dutch.
Details below on the Norwegian version. Continue reading
