Posted onAugust 20, 2023|Comments Off on Activists try to reboot Pacific walrus as climate change icons just as numbers reach a new high
Activists have again resorted to using documentary film to promote Pacific walrus haulout deaths as contrived “proof” of gruesome climate change impacts even as evidence emerges that walrus numbers are higher than at any other time since the late 1970s. Oops! Busted by facts yet again!
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).
Enormously fat Chukchi Sea polar bear, USFWS.
In other words, the assessment that polar bears are currently thriving is not based solely on estimates of a slight increase in global population size but on published data gathered from field studies on the bears’ physical and reproductive health.
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!
Canadian zoologist Dr. Susan Crockford warns that some polar bear specialists are attempting to cast a smoke-screen over the growth of global polar bear numbers.

Yesterday, the US Fish and Wildlife Service announced it will classify the Emperor penguin as ‘threatened’ with extinction under its Endangered Species Act (ESA) based on what are known to be flawed climate models, to take effect next month. This is despite the fact that Emperor penguin numbers increased between 2009 and 2019, an IUCN Red List reassessment in 2019 did not reverse its 2018 decision (still listing it as ‘near-threatened’, not ‘vulnerable’), and member-nations refused earlier this year to enact an Antarctic Treaty to protect the birds. Conservation activists of all stripes are filled with glee at this bettter-than-nothing decision for a species nowhere near extinction because it means more money for them.
Bottom line: An article by the US National Public Radio (25 October 2022) admits the real reason for this listing:
Though emperor penguins are not found naturally in the U.S., the endangered species protections will helpincrease funding for conservation efforts. U.S. agencies will also now be required to evaluate how fisheries and greenhouse gas-emitting projects will affect the population…
Posted onMay 23, 2022|Comments Off on Barents Sea good news: researcher reveals polar bears, even females, still in excellent condition
Barents Sea polar bears had another good year in 2022 despite having lost the most sea ice of any subpopulation but the media and activists can’t help themselves insisting a dismal future is ahead.
Oddly, Norwegian polar bear researcher Jon Aars recently said the quiet part out loud: that he expects Barents Sea polar bear numbers to keep rising, which is rather at odds with the standard narrative:
“What we think is that in the future, if you get less and less sea ice and more and more bears, at some stage they will start struggling and you get fewer bears,” Dr. Jon Aars, a research biologist at Norwegian Polar Institute, told CTV News. [CTV News, 8 May 2022]
“Unexpectedly, body condition of female polar bears from the Barents Sea has increased after 2005, although sea ice has retreated by ∼50% since the late 1990s in the area, and the length of the ice-free season has increased by over 20 weeks between 1979 and 2013. These changes are also accompanied by winter sea ice retreat that is especially pronounced in the Barents Sea compared to other Arctic areas. Despite the declining sea ice in the Barents Sea, polar bears are likely not lacking food as long as sea ice is present during their peak feeding period. Polar bears feed extensively from April to June when ringed seals have pups and are particularly vulnerable to predation, whereas the predation rate during the rest of the year is likely low.” [Lippold et al. 2019:988]
This is has been upheld this year as well, with Aars saying in the video below (6 May 2022) that bears were found to be in excellent condition this spring. In contrast, the media framed this good news within the false ‘polar bear numbers are declining’ narrative, urged on, no doubt, by doom-monger Steve Amstrup.
Amstrup is the paid spokesman for activist organization Polar Bears International, who is identified in this ‘news’ report only as a ‘scientist’, as if he were unbiased, banging on about bears in Western Hudson Bay, where sea ice decline has been a fraction of what the Barents Sea has experienced.
Amstrup’s prophet-of-doom side-kick, Dr. Andrew Derocher (University of Alberta), who worked in the Svalbard area in the 1990s, was wringing his hands in public over sea ice loss in March:
It's incredibly warm in Svalbard. Challenging times for my old study area & the polar bears living there. If this continues, the melt will come early. An early spring melt is correlated with lower polar bear body condition, higher mortality rates & lower reproductive success. https://t.co/TWBcbjyppp
The disappearing ice in the Barents Sea is quite remarkable for March – this is the area within polar bear habitat with the most rapidly disappearing ice cover (>30 days of ice cover lost / decade). https://t.co/LvQ5bTEbVi
It turned out, this wasn’t an “early melt” but pack ice moving in response to wind, as it often does. A bucket-load of angst, all for nothing. Oddly enough, the polar bears figured out a way to not just survive, but thrive! Who would have thought?

Posted onFebruary 24, 2022|Comments Off on Accepted sea otter population estimate at 1911 as inaccurate as rejected polar bear estimate for 1960s
Sea otter specialists, without shame or apology, routinely use a benchmark figure of ‘about 2,000’ for the pre-protection population size of the species at 1911 based on extremely limited evidence yet polar bear specialists refuse to accept a benchmark figure for the 1960s despite the existence of eight published estimates made by experts at the time. Sea otters came much closer to extinction than polar bears did and are not out of the woods yet, for reasons that are not entirely understood (Doroff et al. 2021).
Andrew Derocher, 22 February 2022:‘There never was a population estimate of global abundance in the 1960s.’
Derocher’s statement and those of his colleagues, discussed at length in The Polar Bear Catastrophe That Never Happened, makes them look biased and unprofessional. There is absolutely no rational scientific justification for holding this stance.
Posted onFebruary 10, 2022|Comments Off on Statement of polar bear population size estimates by polar bear scientists in 1965
Polar bear scientists in 1965 published a consensus statement on population size, with no caveats that these were ‘wild guesses’ or not to be taken seriously. They quoted some of the same authorities that I did when I suggested a plausible baseline figure. Andrew Derocher, Steven Amstrup and others who say there has never been population estimates for the 1960 or 1970s are not defending science, they are lying to protect their ‘polar bears are all gonna die because of climate change’ narrative. No other biologists do this, even those who insist the species they study are at risk from human-caused global warming. You should ask why.

The so-called fact-checkers are out again trying to insist one side of a scientific debate is wrong and another is right because they happen to agree with one side. That’s advocacy, not science.

Posted onNovember 4, 2021|Comments Off on ‘Already too late’ to save Churchill polar bears claim a false NY Times climate change cliché for COP26
Not only is it prime polar bear viewing week in Churchill, Manitoba but it’s the week of the 26th international elite COP climate change gab-fest: every media outlet on the planet is eager to promote climate catastrophe talking points.
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.
