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.
In the news today: “Nunavut Draft Plan Says There Are Actually Too Many Polar Bears In Territory” (CTV News via The Canadian Press, Bob Weber, 12 November 2018).

From the Canadian Press story:
“There are too many polar bears in parts of Nunavut and climate change hasn’t yet affected any of them, says a draft management plan from the territorial government that contradicts much of conventional scientific thinking.
The proposed plan — which is to go to public hearings in Iqaluit on Tuesday — says that growing bear numbers are increasingly jeopardizing public safety and it’s time Inuit knowledge drove management policy.
“Inuit believe there are now so many bears that public safety has become a major concern,” says the document, the result of four years of study and public consultation.”
I’ve noted previously that there were two fatal polar bear attacks in Hudson Bay this summer. Both of them happened outside local communities and both happened early during the ice-free period (when bears would have been onshore for only a few weeks). Neither incident can be reasonably blamed on lack of sea ice, an extended ice-free period, or lack of management of problem polar bears within or near communities. The bears involved in the August attack were described as being in good condition.
Update 13 November 2018: See The Guardian‘s take on this story, by a different writer. Despite potential to talk to other polar bear specialists about this issue, only Derocher is quoted. Is no one else talking? “Polar bear numbers in Canadian Arctic pose threat to Inuit, controversial report says” (The Guardian, 13 November 2018).
Update 14 November 2018: See a new CBC story on Inuit perspectives on this issue. “Nunavut community says Inuit lives need to be protected over polar bear population” (CBC News, 14 November 2018).

Just in from NunatsiaqNews (6 September 2018): The polar bears that killed Foxe Basin resident Darryl Kaunak were in good condition, as were the bears who approached the group of hunters after the fact. And the bear that mauled Arviat resident Aaron Gibbons in early July was an adult male in “fair” condition, according to necropsy results.
In all, no evidence that lack of sea ice was to blame. Quotes below.
A man from Naujaat, Nunavut (formerly Repulse Bay) has been killed by a polar bear and her cub, and his two hunting companions injured. The party was found today by a search and rescue team on White Island, southeast of Naujaat after they were reported overdue home on Sunday. A total of five bears were destroyed at the scene: the female and her cub responsible for the attack, plus three other bears attracted to the site and still present when rescuers arrived. This is the second fatal polar bear attack in Nunavut this summer (see previous post here). A very sad day indeed.
Excerpts from news reports below and more details to follow on this incident as they become available. Map below shows location of Naujaat, with White Island about 100 km southeast (off Southampton Island):
UPDATE 6 September 2018: According to examination of the bodies, all of the bears involved (apparently only 4, not 5) were in good condition. See post here and news announcement here.
According to the CBC (28 August 2018), five polar bears were destroyed following the attack [my bold]:
More ‘bears on shore’ news today, this time involving a young polar bear that came ashore in the village of Puvirnituq, northern Quebec and was shot for safety reasons by a local hunter.
This incident is reminiscent of one last year a bit further north (Ivujivik) in early March, which I reported here. Both involved young bears from the large and stable Foxe Basin subpopulation. As I’ve pointed out before, most bears in late winter are at their lowest weight and this can make them very dangerous if they come ashore looking for food.
But unlike the Ivujivik incident, was the first time a bear had ever come into the village of Puvirnituq, making it more like the visit in late February 2017 of a young female bear in Inukjuak further south along the coast, the first such visit of a polar bear to that community in more than 30 years.
The exception to lean condition in late winter being the norm are bears in the Davis Strait subpopulation that have harp seals to feed on by February and are often in good condition by early March, as was the bear reported ashore yesterday in Newfoundland.
Puvirnituq, northern Quebec. Polar bears in this region are part of the Foxe Basin subpopulation.
The news today came via an English language blog post that got an essential detail wrong1, so I turned to Google Translate to offer this version of the original, in French (Journal de Montreal, 7 March 2018):
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.
Sea ice development over Hudson Bay, Hudson Strait, and Davis Strait has been rather unusual this year but what that might mean for polar bears over the coming winter and spring is hard to tell.
Note: The Canadian Ice Service seems to be in the process of updating its sea ice page and graphing features that used to be available weekly on Thursday have not been available until the following week. This means the most recent graphs available are for the week of 11 December (see below).
