W Hudson Bay freeze-up one of earliest since 1979, not “closer to average”

Tundra Buggy Cam_10 Nov 2017_bear headed offshore pmWestern Hudson Bay polar bears have been leaving shore for the rapidly thickening sea ice since at least 8 November (bear above was heading out 10 Nov.). However, Polar Bears International chose not to mention the unusually early freeze-up until the week-long (5-11 November) doomsday bombardment they call “Polar Bear Week” was almost over.

It’s worse than that: two days earlier, PBI’s activist spokesperson Steven Amstrup apparently told the Sierra Club (“People Show Up for Polar Bear Week, But the Ice Hasn’t Yet”; 8 November 2017) that “the bears are still waiting on shore for that ice to freeze” even though ice development had been well on its way for days at that point. As if freeze-up on 10 November came as a big surprise to him, with no warning whatsoever.

Apparently, they didn’t want their naive and gullible supporters to know at the beginning of Polar Bear Week that the sea ice loss of which PBI spokespeople rant about constantly (Save Our Sea Ice) was a total non-issue this year: breakup was not earlier than usual and new ice began developing off Churchill at about the same time it did in the 1980s (last week of October).

As I discussed last year regarding newly-published studies (Obbard et al. 2015, 2016) on the status of Southern Hudson Bay (SHB) bears:

“…SHB polar bears left the ice (or returned to it) when the average ice cover near the coast was about 5%. This finding is yet more evidence that the meteorological definition of “breakup” (date of 50% ice cover) used by many researchers (see discussion here) is not appropriate for describing the seasonal movements of polar bears on and off shore.”

That post (with its list of references) is worth another look for its discussion of the following points: the definition of freeze-up; the relationship of official freeze-up and breakup dates to the dates that bears depart; the overall health and survival of Western and Southern Hudson Bay polar bears.

Below I dissect the misinformation that PBI calls “science communication” in their attempt to minimize the damage caused by this early freeze-up to their message of looming catastrophe for polar bears.

Bottom line: Not only was freeze-up early this year, 2017 will go down as one of the earliest WHB freeze-up years since 1979 and for Southern Hudson Bay bears as well, since as of 13 November there is concentrated ice all the way into James Bay.

UPDATE 14 November 2017: CBC Radio broadcasted an interview yesterday with a recent visitor to Churchill who was remarkably candid about what he saw regarding polar bears, sea ice, and what he heard from locals about freeze-up (“the earliest since 1991”). It corroborates what I’ve reported here. Worth a listen (about 8 minutes):

“Brian Keating: Polar bears in Churchill, Manitoba” (The Homestretch, November 13, 2017, Season 2017, Episode 300312418)

The closest Doug Dirks has come to seeing a live polar bear was at the Calgary Zoo many moons ago. But naturalist Brian Keating has just returned from another trip to Churchill, Manitoba. He joined Doug Dirks with the details of that frosty adventure.

Experts talk of their bleak future, W Hudson Bay polar bears get earliest freezeup in decades

It seems that Churchill residents and visitors woke up this morning to find most local polar bears had left to go hunting — on the sea ice that supposedly doesn’t exist. Right in the middle of the Polar Bear Week campaign devised by Polar Bears International to drum up donation dollars and public sympathy for polar bear conservation!

Polar bear on the sea ice_Churchill_8 Nov 2017_Explore dot org cam my photo 2Frigid temperatures and north winds last night helped the process along, but this early freeze-up has been in the works for almost a week. From what I can ascertain, it appeared the only bears around onshore today were a mother with her young cub moving out towards the ice (females with cubs are usually the last to move offshore, probably to reduce the risk of encounters with adult males who might kill the cubs).

Tundra Buggy cams at Explore.org have been showing markedly fewer bears today and those that have been seen were on the ice (see above and below) or heading out to it.

The chart below is for yesterday (7 November), before the cold and north winds hit the region. It shows the concentration of ice that’s >15 cm thick.

The chart for 8 November is below, after the storm.

Hudson Bay North daily ice concentration 2017_Nov 8

This is ice thick and extensive enough for polar bears to go hunting. Some bears almost certainly left shore yesterday, with the rest following quickly on their heals today. There are sure to be some stragglers left ashore that will leave over the next few days but the fact remains: there is sea ice to be had for those polar bear willing to start hunting.

Watch polar bear on the WHB sea ice below (screen caps below – and one above – were taken the afternoon of 8 November, from the Tundra Buggy Cam live feed near Churchill).

Keep in mind that in the 1980s, bears left for the ice on 8 November, on average. That means we’re back to a 1980s freeze-up scenario, at least for this year.

Funny how no one bothered to mention the potential for an early freeze-up to the media last week, when scientist were so eager to talk about the imminent demise of WHB bears. And funny that Polar Bears International hasn’t tweeted a word today about the famous Churchill bears having enough sea ice to go hunting, smack in the middle of Polar Bear Week.

Yes, the “Save Our Sea Ice” PBI rallying cry sounds a bit hollow with sea ice as far as the eye can see off Churchill today. But will anyone in the mainstream media point out the irony?

See charts below for years back to 2004, on this date (2005 missing for some reason), to compare to the above 8 November image (2004 is as far back as the archive goes).

Problem bear report for Churchill might be second-last one this year

Good news for Western Hudson Bay polar bears that have been getting into trouble in Churchill, Manitoba: the seasons looks to be almost over.  Only a few more days of “Polar Bear Week” likely remain, as sea ice will build along the shoreline in response to severe cold and the north winds expected later today.

Early freeze-up in progress on Hudson Bay – what a difference a year makes

In contrast to 2016, when freeze-up along Western Hudson Bay was about as late as its ever been (early December), ice is already forming along the shore of northern Hudson Bay. There is much more ice than usual for this date, indicated by the dark blue in the latest weekly ice chart below:

Hudson Bay weekly departure from normal 2017 Oct 30

The ice is still thin, as the chart below indicates, but that’s how freeze-up starts. As long as strong winds don’t blow the ice away (as it sometimes does at this stage), the ice gets thicker day by day — and advances further and further off shore. Polar bears get out on the ice as soon as they are physically able, when the ice is about 3-4 inches thick (about 10 cm) or less.

Below is a video of a bear traversing that thin ice yesterday (1 November 2017), near Churchill. Is this a portend of a freeze-up date as early as occurred in the 1980s?

Problem polar bears in Churchill at this date show 2017 less than 2016 and 2015

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):

Problem bear reports confirm Churchill polar bears are in excellent condition

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):

Churchill PB reports_week 7_ Aug 21-27_2017_Aug 28

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:

Churchill_PolarBears_FAT bear post_21 Aug 2017

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).

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):

Churchill_PolarBears_FAT bear post_21 Aug 2017

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.
