Posted onOctober 31, 2021|Comments Off on Global population size estimates for polar bears clash with extinction predictions
How many polar bears are there in the world? This was the primary question the International Union for Conservation of Nature (IUCN) had for the newly-formed Polar Bear Specialist Group (PBSG) back in 1968. Assessing the species global population size was part of the group’s mandate ahead of the 1973 international treaty to protect polar bears from wanton overhunting. For decades, this was an important objective for the scientists that made up the group.
However, about 15 years ago that goal disappeared. I contend it was abandoned because it had become incompatible with the PBSG claim that polar bears are ‘Vulnerable’ to extinction due to human-caused global warming. The group now insists that global population estimates cannot be used to determine if numbers have gone up or down: a Catch-22 that prevents public and scientific scrutiny. This is why they push back so hard when anyone suggests that global polar bear numbers have increased.
Posted onOctober 27, 2021|Comments Off on Fact checkers fail to refute polar bear number increases despite extensive ‘expert’ rhetoric
There’s seems to be something about polar bears that really sets off the climate change fact-checkers. Mention that the situation for the bears is not quite as dire as we were told they would be 15 years ago and they can’t wait to sink their teeth in.
In early September this year, an Australian a woman I’ve never heard of gave a lecture to students at her former girl’s school and in the process made some critical remarks about Al Gore’s ‘An Inconvenient Truth’. Gina Rinehart said, among other things:
“I’d heard that senior school students in a previous headmistress’s time, were having to watch … An Inconvenient Truth. Catchy title, but sadly short on delivery as far as truth is concerned, e.g. the sad loss of polar bears, when actually their numbers have increased…”
The folks who ‘fact-check’ at the Australian Broadcasting Corporation (ABC) seemed to feel that Ms. Rinehart needed to be taken down a peg for the temerity of that remark, perhaps as it afforded an opportunity to take me down along with her: it seems some things I’ve said or published over the last few years were identified by her office as the source of her remark that polar bear numbers had increased.
In a long-winded essay of more than 2,500 words published yesterday (26 October 2021) the fact checkers provide one of the best examples yet of how convoluted is the official answer to the question: have overall polar bear numbers declined or increased over time? They interviewed a number of experts from the Polar Bear Specialist Group (PBSG) who had a lot to say but claimed it is impossible to address the global population issue.
Sadly, the question of how many polar bears exist today compared to decades ago is unnecessarily complicated and messy, as I discovered years ago. I dealt with this topic in my latest book, The Polar Bear Catastrophe That Never Happened, so for now I’ll just quote a bit from one of the chapters and let you decide for yourselves if the experts quoted by the ABC fact-checkers have a strong enough case to say without question that Rinehart was wrong. For example, you might ask why the PBSG experts used the estimate generated for the Kara Sea subpopulation of about 3,000 bears compiled by Russian researchers (Matishov et al. 2014) for their official IUCN 2015 assessment (Wiig et al. 2015; Regehr et al. 2016) but didn’t include that number in this ‘fact-check document – or why they similarly used an estimate of 2,000 for East Greenland for the 2015 assessment but provide no number for this ‘fact-check’. I’ll probably have more to say later.
Posted onMay 31, 2020|Comments Off on Expert reveals size of another Canadian polar bear subpopulation is increasing
In case you missed it buried in the details of my rebuttal two weeks ago about Facebook labelling a short PragerU polar bear video as “false information”, in his review of the video (18 May 2020) Canadian polar bear biologist Ian Stirling revealed that a recent survey of M’Clintock Channel polar bears documented a population increase. The problem is we have no scientific details about the survey – apparently completed four years ago, in 2016 – because the final report has not been made public (COSEWIC 2018, pp. 42-43; Crockford 2020).
I was approached yesterday by Nick Coltrain, a reporter for the Des Moines Register and USA Today, asking for a statement about the accuracy of the PragerU video, which cites me as a source for two of their three ‘inconvenient facts.’
My comments are below but I reminded Nick that what is going on is a classic conflict that happens all the time in science: it presents no proof that I’m wrong or that the PragerU video is ‘false information’. Climate Feedback is not ‘factchecking’: it is presenting its preferred side of a disputed science issue.
Posted onAugust 24, 2017|Comments Off on Pacific walrus haulout two weeks early, US gov’t agency blames “earliest” ice loss
This year’s baseless media frenzy over walrus survival and loss of summer sea ice blamed on human-caused global warming was initiated by a press release from US Fish and Wildlife last week (16 August 2017, pdf here: “Pacific walruses haul out near Point Lay earlier than in previous years“). Quote below, my bold:
In the first week of August, several hundred Pacific walruses were observed on a barrier island near the Native Village of Point Lay, a small, Iñupiaq community on the northwest coast of Alaska. This is the earliest date yet for the haulout to form…This year, sea ice has retreated beyond the continental shelf earlier than in previous years
But is this all true? In a word, no — and it didn’t take much research to uncover the truth.
UPDATE 24 August 2017:A few minutes after this post was published, I became aware that just yesterday, 20 conservation activist organizations, lead bythe Center for Biological Diversity (who led the polar bear listing charge) issued a press release regarding a letter (pdf here) pressuring the US Fish and Wildlife Service to list Pacific walrus as threatened or endangered under the Endangered Species Act. Apparently, a decision must be made by the end of September on whether to actively list walrus or not. The text below has been amended to reflect this development. Continue reading
