Comparing Churchill problem bear statistics over a few years provides some critical perspective: this year, the bears are causing much fewer problems.
This 2nd week in September is no exception, being the 9th week ashore in all cases: 2017 (4-10 September, where I think “total number of polar bear occurrence reports to date” should be 64, not 53, see week 7 report here), 2016 (5-11 September), 2015 (7-13 September), where there were about 1/2 the number of bears in “jail” this year compared to the last two years (i. e., 6 vs. 11 and 12) and slightly more than 1/2 the number of occurrence reports in 2017 than in 2016 and 2015 (64 vs. 107 and 99):
Now that all bears are ashore for the season, the folks at the Polar Bear Alert program in Churchill note in their report for week 7 (21-27 August, 2017) that the bears ashore are in excellent condition (confirming reports on the first bears ashore in July):
Rather marked contrast to the pessimistic spin on conditions from the field a few months ago:
[yes, a few bears fail to make it through the winter, especially young bears; but that has always been the case — it’s not a sign of human-caused global warming catastrophe]
Last week’s problem bear report also confirmed news from the Churchill Polar Bears website a few weeks ago that showed several images of very fat bears:
See below for last year’s report for week 7 and this year’s report for week 8 (28 August-3 September). Western Hudson Bay polar bears that come ashore near Churchill, Manitoba are starting their third month on land this week, out of the five months or so they have spent ashore in recent years (about 3 weeks more than in the 1980s, no longer than they did in 2004 — conditions have not been getting worse).

Churchill, Manitoba Polar Bear Alert Program problem bear reports for weeks 3 (24 July – 30 July 2017) and 4 (31 July – 6 August 2017) show much less activity and fewer problems in this Western Hudson Bay location than were reported for the last two years (2016 and 2015) at the same time (relative to the first reports of the season):
Compare 2017 to last year (2016) at this time, where the problem bear report claims numbers were similar to 2015 (for which I don’t have a week 4 report), with more bears handled and placed in “jail”:
But most Western Hudson Bay bears are at their highest body weight when they come off the ice in early summer and present little risk to humans who keep their distance — few bears cause any real problems this time of year. Compare the above problem bear reports to the blog post from Seal River Lodge, just north of Churchill (5 August 2017, from Churchill Wild Eco-Lodge), which reports seeing 11 bears in one day of viewing. Great photos at this post confirm those bears are in good physical condition and interacting with each other without bothering people.
This is the third week of reports from the Churchill Polar Bear Alert Program but not much in the way of excitement or information, although more bears must be ashore by now.
Compare to last year at this time, when there was much more activity:
There was still some thick ice lingering off the coast of Western Hudson Bay last week, as this weekly ice chart shows:
The first activity report of the Churchill Polar Bear Alert Program has been released for 2017. It comes on the same week as last year’s (so about the same dates for first bears ashore both years), and reports pretty much the same activity.
Odd that this year’s report contains no mention whatsoever of the condition of the bears as did last year’s (see below), which may have brought criticism for spoiling the media ‘message’ that WHB bears are suffering because of reduced sea ice. Better no comment at all than good news, eh?
Sea ice for the week of 10 July off Western Hudson Bay this year consisted of a broad strip of thick first year ice (>1.2m thick) just off shore.
The ice charted above looked like this on a standard ice map:
There are no other reports that I could find of polar bears ashore along the coast of Western Hudson Bay, so these bears must be the first wave.
Habitat for polar bears is abundant worldwide as the prime feeding season passes its peak and mating season for sexually mature bears winds down.
Battle among polar bear males for the right to mate, from this 2011 DailyMail story here.
There is much more ice than usual around Svalbard in the Barents Sea and off Newfoundland and southern Labrador, home to ‘Davis Strait’ bears. There have been no media reports of polar bears onshore anywhere (since the third week of April in Newfoundland and late January in Svalbard).
Sea ice map below for 12 May 2017:
Compare the extent and concentration of ice around Svalbard above (at 12 May 2017) to conditions that prevailed on the same date in 2015 (below), considered a “good ice” year for local polar bears (and the year of the last population size count which registered an increase over the 2004 count):
There hasn’t been this much ice in the area at this point in the season for many years, especially to the north of Svalbard, and levels since late April have been above even the long-term average (disregard the huge downward blip, which is clearly a sensor malfunction of some kind):
In fact, ice is pretty solid throughout the Barents Sea and East Greenland at this time:
Across the Atlantic, the situation is similar, with unseasonably heavy sea ice off eastern North America and the Southern Beaufort Sea.
