Was COP26 ‘People’s Advocate’ Sir David Attenborough talking about global temperatures, polar bears, walrus or even orangutans when he recently called for bold action to save the planet? You might assume so but I believe you’d be wrong.
However, in a long BBC interview he gave last year, Attenborough revealed his true colours. It suggests he isn’t actually advocating for the planet at COP26, or even the poor people of the world or threatened wildlife.

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.

The possibility that a polar bear somewhere in the Arctic might occassionally be successful at stalking and killing a reindeer (aka caribou) shouldn’t surprise anyone, let alone a biologist on Svalbard. But having video footage of the event makes it immediately newsworthy, especially when the researchers vaguely suggest that global warming might be to blame.
The title of the scientific paper that has generated the latest polar bear hype is called ‘Yes, they can: polar bears Ursus maritimus successfully hunt Svalbard reindeer Rangifer tarandus platyrhynchus’ (Stempnlewicz et al. 2021).
Would any serious scientist really think they couldn’t?
Posted onOctober 20, 2021|Comments Off on Most Chukchi Sea ice in 20 years means no walrus feasts for polar bears at famous Russian cliffs
After years of hype, including documentary over-reach by David Attenborough and his collaborators at WWF and Netflix, there has been relatively abundant ice in the Chukchi Sea this summer, particulary along the Russian coast and around Wrangel Island, which in recent years have been important summer refuge areas for polar bears and Pacific walrus.
This year, there has been nothing like the complete retreat of ice into the Arctic Basin as happened in 2007, 2012, and 2020. The chart below shows the ice extent at 11 October 2021:
Wrangel Island was surrounded by ice in 2000 and 2001, which made access to walrus haulouts on the island impossible (Kochnev 2004). Most of the walrus haulouts along the Chukotka coast were also ice-covered in September in those years, as were all of the western locations in 2021 – as the ice charts below show. The extra ice will have drastically affected the distribution of walrus this year, which in turn will have meant no walrus carcasses for polar bears to feast on as they have done for many years now.
Posted onOctober 18, 2021|Comments Off on Behold the walrus publicity stunt the WWF calls ‘science’
All you can do is laugh, really. The World Wildlife Fund (WWF) has been pushing for years to position itself as a valid scientific authority but the kinds of projects they get involved with generally have little to do with real science and more to do with promoting their brand and its doomsday climate change narrative. The most recent example is a ‘Count walrus from space‘ ploy that is enlisting elementary school aged children and other members of the public to count Atlantic walrus from satellite photos, which the Washington Post obligingly promoted last week (proving the WWF massive free publicity).
The first problem with this plan is that evidence is lacking to support the claim that walrus have been harmed by recent declines in sea ice. Despite current low numbers, Atlantic walrus are more abundant today than they were 100 years ago, after decades of commercial hunting reduced populations to near extinction levels (Born et al. 1995; Wiig et al. 2014).
The second problem is that walrus at land haulouts in summer or fall are notoriously difficult for professional scientists to count even from aerial photographs. The idea that children as young as nine years old can contribute to generating a more accurate count from satellite images is ludicrous.

I’ve been told that another complete aerial survey of the Western Hudson Bay polar bear subpopulation (from the Nunavut to Ontario boundaries) was conducted in August this year and that the bears have been hanging out further south than usual. It will be years before the results of the population count are published, of course (especially if it’s good news) but my contacts also say virtually all of the bears are in great condition again this year.
Posted onOctober 8, 2021|Comments Off on Churchill problem polar bear reports finally completed and posted online
Although since 2015 at least the Polar Bear Alert Program in Churchill Manitoba usually issued and published its problem bear reports weekly during the ice-free season, this year has been an odd exception. Two reports in early July, then nothing. Yesterday, there was a dump of reports that had been compiled on 1 September and 7 October, according to their metadata.
There are still a few weeks missing, including the two most recent weeks but at least now we have a more complete picture of what’s been going on with problem bears in The Polar Bear Capital of the World that can be compared to previous years. Such reports in various forms go back to the late 1960s, although only those from recent years have been publicly available (Kearney 1989; Towns et al. 2009).
Posted onOctober 7, 2021|Comments Off on Alaska polar bear researchers claim poor sea ice limited spring field work in 2021 more than 2019
According to an Inside Climate Newsreport, polar bear researchers at the US Geological Survey had trouble darting bears in the Southern Beaufort Sea in March-May of 2019 and 2021. They claim their research program was hampered by thinner-than-necessary ice for safely landing the nearly 4,000 lb. outfitted helicopter (with crew and gear) in 2019 but that conditions in 2021 were even worse (it is implied work proceeded in 2020 despite pandemic restrictions but no data for that year are discussed).
However, this claim of worse conditions in 2021 is not corroborated by reports from sea ice experts and ice charts for the Southern Beaufort this spring, where thick first year and multiyear ice was present from March through June. Ice didn’t begin to pull away from landfast ice to form patches of open water near the Canadian border until late April 2021 compared to early May in 2019 (as it did in 2016), as shown in the video and charts below. Moreover, the researchers oddly fail to mention that the presence of thin ice and open water in spring is essential for polar bear survival in the Southern Beaufort, a fact which has been documented and discussed in the scientific literature by their colleagues.
