Recent incident in Foxe Basin shows the danger of hungry polar bears in winter

A late-night encounter with a thin and hungry polar bear in the northern Quebec community of Ivujivik in early March was a nightmare-inspiring event.

Reported this morning by NunatsiaqOnline (Nunavik community receives some unwelcome guests, 28 March 2017), the thwarted polar bear attack at the edge of Hudson Bay was the fourth defense kill this year (and the second this month) after a large number of bear sightings by residents this winter.

In contrast to reports of other encounters this winter that involved unusually fat bears for this time of year, this bear was thin and obviously dangerous.

Late winter polar bear habitat 2017 vs. 2006 and 2011 shows no trend

Here is a bit of historical perspective for rational readers trying to make sense of the doom-mongering of others that current sea ice conditions spell trouble for polar bears, given that the winter maximum extent for 2017 reached a new seasonal low (keeping in mind that NSIDC does not publish error bars for these measurements, which helps elevate such pronouncements to “news”).

Ice extent (courtesy NSIDC’s MASIE) at 25 March (Day 84) is below for 2017, 2011 and 2006, almost 3 weeks after the winter maximum was declared at 7 March for 2017, 9 March for  2011, and 12 March for 2006. Extent at the maximum for 2006 was estimated at 14.68 mkm2, 14.42 mkm2 for 2017, and 14.67 mkm2 in 2011 (what tiny differences make headlines these days).

Remember: there are no polar bears in the Sea of Okhotsk or in the Baltic Sea (marked with an * below) yet ice in those regions is included in the Arctic totals used to determine maximum seasonal extent. Much (and sometimes, all) of the “Arctic” variation in extent at this time of year is accounted for by variation in Sea of Okhotsk and Baltic Sea coverage.

Bottom line: total winter ice extent for the Arctic ≠ winter polar bear habitat and neither have changed much in a decade.

Another fat bear onshore in late winter, along Gulf of St. Lawrence north coast

Another fat bear onshore in late winter, this time along the Quebec shore of the Gulf of St. Lawrence (22 March 2017) – and this time, one of the witnesses to the sighting took some great photos. Courtesy CBC News (Polar bear makes rare appearance on Quebec’s Lower North Shore 24 March 2017).

Exposing the failed polar bear scare to a an enthusiastic and influential audience

I’ve just returned from a few days in Washington DC, where I presented the details on the global warming icon that refused to die as modeled (see my slide #12 below) to an enthusiastic and influential audience at The Heartland Institute‘s 12th International Climate Change Conference (ICCC-12).

Polar bear science got some long overdue scrutiny by a large number of people at this meeting. Not unexpectedly, a good many folks were surprised and outraged to learn how the polar bear/sea ice situation has actually unfolded compared to the predicted outcome and on-going media hype.

Prehistoric polar bear find has elongated body type Inuit know as a ‘weasel bear’

A story that broke in Alaska newspapers a month ago made the UK press this weekend about the archaeological discovery of 1,300 year old polar bear skull that may be associated with an unusual body type known to Inuit hunters. See the Mail Online cropped headline below, full story here – and some quotes and critical background below.

Several fat polar bears sighted in southern Labrador early this week

Seven polar bears came ashore this week, either passing through or exploring, in Black Tickle, Labrador. It’s not that unusual an occurrence but the take home quote sure is:

“They look really healthy … they have been eating good, these ones have.”

Lucky for them – residents in my novel – EATEN – were not so lucky.

A bear onshore along eastern Hudson Bay late last month was also described as fat.

Report of Hudson Bay polar bear onshore in winter is rare indeed – here’s why

Late February is still the dead of winter in the Arctic, a time when most polar bears are at their leanest and out on the sea ice trying to find seals – and that means yesterday’s report of a “very fat” polar bear onshore outside Inukjuak is unusual at face value – but my followup inquiry revealed details that make it even more startling.

CBC North facebook entry 27 Feb 2017

At my request, CBC North reporter Priscilla Hwang reached out to the hunter involved, who is the mayor of the community. She was told the incident took place on Saturday 25 February 2017 and the very fat bear in the story was actually a young, subadult female.

Subadults are more likely to be in poorer condition than adults at any time of year, due to their lack of hunting experience and competition with adult males. So to see a young bear that’s very fat before the feeding begins is quite astonishing: it suggests that feeding opportunities out on Hudson Bay have been very good over the winter and/or this bear was a savvy hunter despite her youth.

According to the mayor’s report, this community hasn’t had a bear onshore in nearly 30 years. Polar bears in Hudson Bay travel with the retreating ice to the western and southern shores, so with some exceptions, bears usually only have access to the east coast during winter through spring.

Last winter saw an extraordinary number of reports of bears on shore in winter, most of them causing trouble (see summary here). This Inukjuak sighting is the second I’ve come across this year – the other was in Svalbard (a female with cubs). Whether this new pattern is due to more bears or lack of hunting leading to bears having less fear of people – or a bit of both – it’s not yet possible to say.

So under the circumstances, the mayor of Inukjuak’s decision to kill this bear for the protection of the community seems quite reasonable (given the extensive resources required in Svalbard to drive their problem bears away rather than kill them).

Excerpts from the CBC story, and some maps and charts, are below.
