Fat polar bears [and lots of them] drive public confidence in future of the species

What is causing the death of the polar bear as a climate change icon? Fat bears are part of it, but mostly it’s the fact that polar bear numbers haven’t declined as predicted.

Western Hudson Bay polar bears around Churchill, Manitoba appear mostly in good shape this summer despite the very late freeze-up last fall, including the very fat bear caught on camera below (see more great pictures here):

Not only have we been seeing pictures of fat bears rather than starving bears in recent years but there are lots of them, in Western Hudson Bay and other seasonal sea ice regions where there should be none (if the models had been correct). No wonder polar bears are falling out of favour as an icon for catastrophic human-caused global warming.

[Here’s another picture of a fat bear, this one from Svalbard]

Excuses for why the public is no longer worried about the future of polar bears include a recent claim by climate scientist Michael Mann that “by making polar bears and penguins the poster child for climate change, we have wrongly conveyed that this is some exotic problem far off.

But none of these apologists acknowledge the simple truth: the models that  predicted catastrophe for polar bears due to diminished summer sea ice turned out to be wrong. The sea ice declined but polar bears flourished. Polar bears in seasonal sea ice ecoregions like Western Hudson Bay and Baffin Bay didn’t die off due to climate change as people were told would happen — why should they believe any of the other scare stories?

In and around Churchill, where tourists flock to see Western Hudson Bay polar bears up close and personal, one bear in good condition recently ran through town:

Overall, there have been fewer problems or conflicts this year in Churchill compared to last (after 6 weeks of onshore living), see below.

Polar bears are no longer a useful global warming icon because they are thriving despite diminished sea ice: Churchill area polar bears are a good example.

Churchill polar bear reports still showing fewer problems than last year

Churchill, Manitoba’s Polar Bear Alert Program is still reporting many fewer problems with polar bears onshore than it did last year at the same point in the ice-free season (week 5, 7-13 August):

Compare to week five last year (2016), when bears came ashore in excellent condition:

2016 Aug 8-14_week 5

Although it’s been warmer than average recently (25.4 degrees C yesterday, expected to reach 29 degrees C today and 28 degrees C tomorrow), according to Environment Canada weather records, that’s not even close to an August record-breaker temperature for Churchill. Continue reading

Churchill polar bear reports to 6 August show fewer problems than last two years

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):

Churchill PB reports_week 4_ July 31- Aug 6_2017

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.

Churchill polar bear report 24-30 July rather boring compared to last year

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:

Churchill polar bear report 17-23 July 20: those ashore appear to be in great shape

Just out from the City of Churchill: few polar bears reported onshore for the week of 17-23 July 2017 (week 2) but those seen “appear to be in great shape.”

Update 24 July 2017 12:20 PM: Just spotted this blog report from Churchill Polar Bears” that I somehow missed last week, which includes what seems to be the first polar bear photo’s of the season (of a sow and two chubby cubs) that are also in fine condition.

ChurchillPolarBearsDotOrg_July 14 2017 Alex De Vries photoThe photos were taken by Churchill photographer and guide Alex De Vries on Thursday 13 July and I hope he doesn’t mind my including one of those here as documentary evidence of the good body condition of this mother and both her cubs — see more photos at the Churchill Polar Bears blog post dated 14 July here.

Compare last week’s PB Alert report above to last year’s (below):

Problem polar bears of Churchill: first report of the season similar to 2016

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.

Churchill PB reports_week 1_ July 10-16_July 2017

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.

Western Hudson Bay polar bears reportedly still on ice as of 17 July 2017

Today, polar bear biologist Andrew Derocher posted a progress report via twitter on the annual journey ashore of the Western Hudson Bay bears tagged by his University of Alberta research team that shows virtually all of the bears are still out on the sea ice.

Churchill_Polar_Bear_2004-11-15 Wikipedia

After months of gloomy reports on the state of the Hudson Bay sea ice, it’s clear from the map Derocher posted (below) that only one bear out of 12 still transmitting has come ashore so far, although he comments that “some tags haven’t reported lately” (the purple icons are ear tags put on males &/or young bears while the blue icons are collars put on adult females):

Oddly, the same comment was made almost a month ago about these same bears and the suggestion was made that these animals “may be swimming to shore”:

Money quote: Today Derocher remarked that “bears may be shifting behaviour to stay out on less ice” to explain why the tagged bears have still not come ashore as he expects them to do.

Perhaps if he used a different ice chart, it might make more sense (see below). However, the same thing has been happening year after year: WHB polar bears stay on the ice much longer than Derocher predicts but he does not change his expectations or the type of ice chart he uses to track the bears.

As I’ve pointed out before (because this is what field researchers have stated), polar bears have a tough time catching seals after about mid-June or so but they may still prefer to be on the sea ice than on land, even if it’s low concentration ice.
