Heads up Newfoundland & Labrador: polar bear season has begun

There is now enough sea ice off southern Labrador and the northern tip of Newfoundland for Davis Strait polar bears to come ashore looking for food. Baby seals won’t be available for months yet. And since winter is the lean season for these bears, some may seek food sources onshore. The bears come down from the area of Hudson Strait and southern Baffin Island: as the sea ice expands south, so do the bears.

Biologists escalate conflict over Inuit management of polar bear populations

Yesterday, two polar bear specialists and an inept freelance journalist poured gasoline on the already-volatile issue of polar bear management in Nunavut.

Quote of the day: “I think there’s a reasonable chance that the last polar bear in Canada will be shot by an Inuk hunter.” [Andrew Derocher, University of Alberta]

You have to read it to believe how bad the Yale Environment 360 article by Gloria Dickie (19 December 2018) really is: “As polar bear attacks increase in the Arctic, a search for solutions.” [reprinted 26 December at PBS] The title suggests a balanced treatment of the issue but the reality is far from that: gross inaccuracies in the descriptions of the two fatal attacks that took place this summer that can only be explained by sloppy research and what struck me as unbelievably nasty and racist commentary by polar bear specialist Andrew Derocher. But decide for yourself.

CBC hypes “bleak” Churchill polar bear fate with unsupported claims & falsehoods

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.

Unfounded concern for polar bears from onshore oil exploration in Alaska

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.

Canadian polar bears still not threatened with extinction says conservation committee

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.

Inuit and Western science are far apart on polar bear issues in Nunavut

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”).

sow_yearling_USGS

“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.”

No extirpation looms for Svalbard polar bears: no pending catastrophe in Norway

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.
