At least a month earlier than in more northerly areas of the Arctic, the first known female with new cubs-of-the-year has been reported on the sea ice hunting for seals in Western Hudson Bay. Remember this when the cries of “early” breakup of sea ice on Hudson Bay come in the summer: these WH bears routinely get a head start on spring feeding that other bears don’t get.

Even though it’s in graph form only, we finally have an update on sea ice freeze-up dates for Western Hudson Bay for 2016-2020 (but not breakup dates).
This graphed data published by Miller et al. 2022 extends by five years that published in 2017 by Castro de la Guardia and colleagues, which contained graphed data for breakup and freeze-up dates from 1979-2015 (with exact dates for 2005-2008 only).
It confirms a statement I made last month, that between 2016 and 2021 “there has been only one ‘late’ freeze-up year (2016)–but five very early ones.” Of course, 2021 was not included in this new dataset, so that would be “four very early ones” up to 2020.

Polar bears are supposed to starve before they die, the experts said. They said only a few years ago that dead or emaciated individuals onshore were evidence that many polar bears would soon be dying of starvation out on the sea ice. So, if the Western Hudson Bay (WH) subpopulation had indeed dropped by 27% by late summer 2021 as researchers claimed, where are all the photos of starving bears in the fall of 2020, the year before the count? The photo below of a thin female and cub was taken in late fall of 2021 (the year of the count) by a stationary web cam. In other words, some bears came off the ice without an optimal amount of fat because of poor hunting conditions over the winter but they were still alive. We know that 2020 had the shortest ice-free season in at least 20 years (and no similar images were captured), so bears went into the winter of 2020/2021 in good condition. Ditto for 2017-2019. In contrast to 2021, in 2016 (the year of the previous survey that also indicated a declining population size), bears reportedly came off the ice in good condition.
All I’ve seen are photos of fat bears and fat cubs, even a triplet litter in fall 2020. The shore of WH near Churchill should have been abounding with starving bears in 2020 (and in 2015), if the experts were right about starving bears preceding a population decline. More importantly, where are the studies on food-deprived bears onshore, as were done in the 1980s when WH bears were emaciated and cub survival poor (e.g. Ramsay et al. 1988)? WH bears are being used exclusively to model an implausibly pessimistic future for polar bears across the entire Arctic (Molnar et al. 2010; 2020), which means lack of good science for WH polar bears has big consequences. Covid restrictions in two of those ten years don’t excuse lack of study on this phenomenon.

Canadian government scientists created headline news worldwide last week when they told the media that Western Hudson Bay polar bear numbers appeared to have declined by 27% between 2017 and 2021, based on a survey report that has not been made public. This is called ‘science by press release’. Its practice is rightfully considered unethical, as it is usually associated with “people promoting scientific ‘findings’ of questionable scientific merit who turn to the media for attention when they are unlikely to win the approval of the professional scientific community.”
Not surprisingly, all of the stories stated or implied a strong association between this purported population decline and lack of sea ice due to ‘climate change’. However, sea ice conditions have been particularly good over the last five years–for both freeze-up and breakup dates–calling into question how ‘lack of sea ice’ could possibly be to blame for the apparent decline.
A Reuters story (dated 23 December 2022) admits this is the case and included another critical caveat that only one news outlet I saw bothered to mention, which happened to be BBC News:
Scientists cautioned a direct link between the population decline and sea ice loss in Hudson Bay wasn’t yet clear, as four of the past five years have seen moderately good ice conditions. Instead, they said, climate-caused changes in the local seal population might be driving bear numbers down.
For example, an Associated Press story published the day before (22 December 2022), picked up by many other outlets, did not include these critical pieces of information about recent good sea ice conditions and possible declines in seal abundance.

Another pronouncement from conservation activists at Polar Bears International taken without a single check of facts makes the BBC look ineffective and gullible.
The photo above of a ‘green dot’ bear was taken 10 November 2022 by a Churchill resident. Bears released from the ‘polar bear jail’ when there is enough sea ice for them to resume hunting are marked with a green dot.

Svalbard is still ice-free this fall, which it has been rather consistently for at least ten years but the amount of sea ice greater than ‘normal’ in the Eastern Canadian Arctic at this date is something to behold. Yet contrary to predictions, polar bears in Svalbard are thriving.

Polar bears, including a litter of triplet cubs (a sign of very good health), are gathering near Churchill, Manitoba where new ice is forming along the coast. This means the fall seal hunt will soon begin, depending on the winds (it might be a few days from now or a few weeks).
See below for some of the images of bears on the shore of Wapusk National Park taken by Explore.org video cams from Tundra Buggy-based cameras, as well as the most recent Churchill problem bear report.

The remote and isolated Shamattawa First Nation in Manitoba was threatened last weekend by a large male polar bear in good condition prowling around but the bear was eventually captured near the dump and released near the coast without incident. No one blamed this wandering bear on climate change.
Another bear visited the community in August 2010, also without incident. See map for location and news report excerpts below.

Despite continued dire predictions of catastrophy, polar bears in Western Hudson Bay are behaving like the well-fed predators on holiday they are: bears are causing few problems in Churchill and poking around Arviat, seemingly out of curiousity rather than actively stalking prey.
Bears are chased out of Western Hudson Bay communities due to an abundance of caution but so far, no frightening encounters have been reported that I’ve heard about. That’s true elsewhere as well: an uneventful summer for polar bear attacks is good news indeed.

From the live cams installed on beluga tour boats running near the Churchill River, we have some good photos of a few fat polar bears onshore in Western Hudson Bay.
These bears were attracted to the remnants of a beluga carcass with nothing much left on it (lower right in the photo) and stayed around for at least a few days. The female with her cub-of-the-year was remarkably tolerant of an adult male nearby.
