Posted onFebruary 23, 2023|Comments Off on Published field study observations – not population size – prove polar bears are thriving
There is irrefutable evidence from Barents and Chukchi Sea subpopulations, among others, that polar bears are fat and reproducing well despite marked declines in summer sea ice over the last two decades. These indicators of physical and reproductive health, in any species, are signs of thriving populations. However, these facts negate the premise that polar bears require abundant summer sea ice to flourish, and that creates a problem for polar bear specialists who continue to make that claim (Amstrup et al. 2007; Crockford 2017, 2019).
Oddly, biologists repeatedly turn to data from Western Hudson Bay to drive home to the public their preferred message that polar bear health and abundance are being negatively affected by recent summer sea ice declines. However, they fail to mention that robust field data from many other regions, including the Barents and Chukchi Seas, support the opposite conclusion. Moreover, wherever possible, they mumble under their breath (or leave out entirely) the fact that poor ice conditions could not be blamed for a 27% decline in polar bear numbers in Western Hudson Bay since 2016 — because their own data showed sea ice conditions had been strong!

The veterinarian who examined the bear responsible for the fatal attack in Wales, Alaska, three weeks ago said the bear was an “older” adult male in poor physical condition: the most dangerous bear for anyone to encounter. Recall the armed cruise ship guard who was ambushed and mauled by a desperately thin bear in July 2018 in the Svalbard archipelago–and only survived because his colleague was able to shoot the bear quickly. In this most recent attack, Summer Myomick and her 1-year-old son, Clyde Ongtowasruk didn’t stand a chance as they were ambushed in a driving snowstorm just steps from the safety of the community school they had just left.

Posted onJanuary 12, 2023|Comments Off on Recent paper on W. Hudson Bay polar bears includes new official sea ice freeze-up data
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.
Posted onAugust 31, 2022|Comments Off on Video: Fat polar bears on the shore of Hudson Bay near Churchill, one catches a goose
This little snack won’t make much difference to the bear’s survival but rare film footage of an already-fat bear (estimated at 1,000lbs) catching and eating a Canada goose on Friday last week (26 August 2022) just outside of Churchill on the western shore of Hudson Bay is not a bear motivated by starvation to eat something other than seals.
Newsreel of the goose hunt is below; photo of another fat bear, also near Churchill, taken the day before (25 August 2022) is shown above, see more from that day here.
Funny how these reports in recent years (these included) don’t mention the condition of bears the way they used to as recently as 2017 (or the state of the sea ice). I guess it’s so they can’t be used as evidence against the prevailing mantra that western Hudson Bay polar bears that spend the summer onshore are starving because of the lack of ice due to human-caused global warming!
Posted onJuly 29, 2022|Comments Off on Most Hudson Bay polar bears are still offshore, excellent ice conditions for late July
With only a few days until the end of July, most Western Hudson Bay polar bears are still on a thick band of thick first year ice that remains close to shore. The few bears that have come off the ice appear to be nice and fat, indicating they had good spring feeding conditions.
We’ll have to wait a few more weeks to see if this year shapes up as it did in 2020, when the last of bears didn’t come ashore until the third week of August, despite there being very little visible ice. Last year, most of the bears were ashore by the end of July.
In the case of ‘Our Planet’, WWF bankrolled the film series for Netflix to ensure the content they desired; in ‘Polar Bear’, the tables are turned: DisneyNature is paying PBI for their assistance getting the polar bear film shots and providing their biased content, via money they are calling a research grant. I think you know by now what to expect. However, here are the facts about polar bear conditions in Svalbard, where the film was shot, and some good news from Western Hudson Bay this year, courtesy of Mike Reimer and his team at Churchill Wild. In short, there is still no climate emergency for polar bears: the hype is based on old models that failed spectacularly and new ones which depend on old data and totally improbable climate scenarios (Crockford 2017, 2019; Hausfather and Peters 2020; Molnar et al. 2020).
Posted onDecember 1, 2021|Comments Off on Higher than average Svalbard sea ice extent in November 2021 has implications for birth of cubs
Early last November, sea ice around Svalbard was the lowest it had been since 1967 and pregnant females were simply unable to den on the eastern islands of the archipelago and instead had to make their dens and give birth in the pack ice or the Franz Josef Land archipelago further east, as they have done before. However, the ice is back this fall with a vengeance: even Hopen Island in the south of region was surrounded by ice well before the end of the month but whether it will attract a few pregnant females remains to be seen.
Hence totally expected that the New York Timeswould print someone’s unsupported claim that the polar bears of Churchill (part of the Western Hudson Bay subpopulation) are on the verge of extirpation due to lack of sea ice and other similar nonsense. Also not surprising to find that Canadian government biologist Nick Lunn used the occasion to again offer unpublished and misleading data to a reporter. However, this time it’s good news meant to sound like an emergency: if correct, the data he shared indicate polar bears are heavier now than they were in the 1990s and early 2000s.
