Ryrkaypiy ‘over-run’ by >50 polar bears is probably due to more Chukchi Sea bears

A scary-sounding headline from the BBC today screams “Ryrkaypiy: Far-north Russian village overrun by polar bears“. A little research would have shown (as I do below) that this sort of event is not unusual for this village, there is adequate sea ice off the coast to allow polar bears to hunt for seals if they choose to do so, and the photos provided do not support the claim that almost all of the polar bears “appeared to be thin” (see photo below and others). Similar incidents happened in 2013 and 2006. Increasing numbers of Chukchi Sea polar bears is the most plausible explanation for the recent abundance of bears at this village.

BBC Russian village Chukotka over run by polar bears BBC 5 Dec 2019 headline

BBC headline, 5 December 2019. Does that look like garbage these fat bears are feeding on or the frozen remains of dead walruses at the base of the Cape Schmidt cliff?

UPDATE 8 December 2019: A Daily Mail version of the same story (6 Dec) confirms the photo above is of bears feeding on walrus remains (not garbage) and has many more photos (plus a video) of a large number of bears, not a single one of which that I saw was ‘skinny’ (see quotes from the story below). See also the Siberian Times version (6 Dec) with the same pictures. My source for the story was an article published by the BBC, which ran the day before (5 Dec).

UPDATE 9 DECEMBER 2019: Now it’s apparently 63 polar bears threatening the village of Ryrkaypiy on the Chukotka coast, according to the Siberian Times yesterday and repeated by the Daily Mail (with more pictures and video). Russian media getting lots of mileage out of this one. The story now says the bears are feeding on “seals”, not walrus (to deflect attention over their long history of walrus/polar bear problems? Or just a bad translation?). Both stories repeat the claim that most of the bears are “skinny” despite the photos showing just the opposite: lots of fat, healthy bears.

Also, uniquely (and rather bizarrely), the Daily Mail piece claims the bears are being deprived of the “fish” they should be consuming:

Instead of hunting for fish in deeper waters , the bears are eating seal carcasses left in autumn.

Last year army servicemen cleared the village’s shore of remains of dead seals on which the bears are feeding.

Obviously written by someone who knows absolutely nothing about polar bears, who rarely, if ever, eat fish and certainly would not be eating fish at this time of year. Sea ice map below for 8 December 2019 from the Alaska Sea Ice Program for 8 December shows, as noted below, that there is enough ice offshore for the bears to hunt seals if they chose to do so (since eating long-dead walrus is much easier than going hunting):

UPDATE 14 December 2019: Apparently, the number of invading bears is now 72 (number gets higher every time someone asks, even though they are still talking about “about a week ago”: who exactly is doing the counting?), according to a story today in The Times (UK). Residents say they move walrus carcasses “away” from the village to a “feeding point” for the bears but it’s apparent the distance is insufficient to prevent problems with bears coming into town. While a local cleaner working for the polar bear patrol (well indoctrinated by the WWF who sponsor the program), proclaims the problem is “definitely” due to climate change, there is finally the admission in this article that the bears coming into town are young bears driven away from the walrus carcasses by larger, older animals (i.e. intra-specific competition). This piece also has a few new photos, including one (below) of fat bears getting into garbage (still no photos of the so-called “skinny” bears said to dominate this “invasion”) and also is the first I’ve seen that doesn’t state that there is no sea ice (only that the ice extent is lower than usual). Some progress, but balanced by the hype promoted earlier this week (at “Treehugger” – what a surprise) by former WWF activist Geoff York (now at Polar Bears International), who is still blaming this incident on lack of ice.

First polar bear spotted off the ice in Western Hudson Bay is fat and healthy

One of the first of hundreds of polar bears expected to come off the sea ice of Hudson Bay along the west and south coasts was captured on video on 5 July. This is only the first wave, as there is still so much ice remaining that most of the bears are likely to remain offshore: not because there is so much food available (few seals are caught at this time of year) but because the ice is where they are most comfortable.

Images from 2017 and 2018 show polar bears thriving in a warming world

Candid images of fat, healthy bears taken over the last two years by unbiased photographers across the Arctic are representative of the state of polar bears in a world that’s warmer than it was in 1980.

Chukchi Sea polar bear on the sea ice, early August 2018. A Khan, NSIDC. Chukchi Sea bears are thriving, according to a new survey of the population.

It may seem counter-intuitive but it’s true: polar bears are thriving with less summer sea ice and there are more bears now than there were in 2005 (not a statistically significant amount more, but more nevertheless).

Svalbard polar bears doing fine with much less sea ice say Norwegian biologists

“…despite the loss of good denning areas and a shrinking habitat for hunting, Svalbard’s bears seem to be doing fine.…The sea ice season is now several months shorter, and the ice edge typically lies several degrees further north than what was normal 20-40 years ago….Polar bears can survive long periods without food, provided they have accumulated a good fat reserve during the few months in spring and summer when sea ice is present, and seals are abundant.” [Jon Aars, Norwegian Polar Institute, 2018]

Jon Aars from the Norwegian Polar Institute has written an update on the status of Svalbard polar bears for the general public (The Barents Observer, 8 January 2019, republished from a story published by The Fram Centre in their newsletter: Population changes in polar bears: protected, but quickly losing habitat).

Derocher admits Western Hudson Bay polar bear population may not be declining

Earlier this year, I challenged a journalist to ask to see the data used by Andrew Derocher and his colleagues to support their repeated claims that Western Hudson Bay polar bears are having trouble surviving. It almost happened.

Polar bears_Gordon Court_Committee on the status of endangered wildlife in Canada Dec 2018

David Rose, writing for The Mail on Sunday, has produced an excellent feature on the conflict between Nunavut Inuit and biologists about polar bear management, got Andrew Derocher to tell the truth about current polar bear health and survival.

Or, to be more precise, to waffle a bit on his standard message of doom:

“Even Prof Derocher, who is convinced the bears’ long-term future is bleak, accepts that ‘the wheels are not coming off yet’, while ‘some bear populations are doing fine’. In West Hudson Bay, there has been ‘a recent period of stability’, he says, and though ‘we were seeing starving bears, starving cubs on land, that seems to have slowed down’. Then again, the computer models ‘are not great on the 5 – 10 year time-frame’, and it was possible that although the Arviat bears might look healthy now, they may be about to ‘fall off a cliff’.” [my bold]

This concession by Derocher suggests that Western Hudson Bay bears indeed are thriving, because he’s the guy who holds all the data. But he couldn’t help adding that disaster might be just around the corner.

But did he actually produce the data that show what’s been happening with cub survival or the body condition of females since 2004? Apparently not — but his admission that conditions are not as bleak as he continually portrays them suggests he is covering for data that says the same: polar bears in Western Hudson Bay are doing just fine and Inuit are right to be worried.

This may be as good as it gets unless the people of Nunavut can force Derocher to show his data.

Read the whole story here: “Why all you’ve been told about these polar bears could be WRONG: Animals driven to the edge of their natural habitat by shrinking ice have become one of the defining images of climate change, but Inuits who know the predators have a very different story.” (The Mail on Sunday, David Rose, 30 December 2018).

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.

Critical evidence on W Hudson Bay polar bears still not published after 25 years

Polar bear researchers have been doing capture/recapture studies in Western Hudson Bay for decades yet most of the data claimed to be critical for assessing effects of human-caused global warming on this species have not been published. I raised this point in one of my early blog posts (27 Sept 2012) but the situation has not changed in 6 years. Here’s an update.

Derocher in the field in WH_CBC story 2016

From CBC story 14 Sept 2016.

Years ago now, in an oft-cited paper, Stirling and Derocher (2012) claimed to summarize the evidence that climate warming was negatively impacting polar bear health and survival. Several life history parameters were considered crucial, particularly body condition.

Despite almost a dozen papers (and perhaps more) on various aspects of WH polar bear health and life history studies based on capture/recapture data published since 2004  (e.g. Castro de la Guardia 2017; Lunn et al. 2016; Pilfold et al. 2017), none have reported the body condition data that supposedly support the claim that sea ice loss is having a severe impact — and the same is true for litter size, proportion of independent yearlings, and cub survival.1
