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!
Posted onAugust 12, 2022|Comments Off on ‘Alone’ and ‘Alone Frozen’ survivor reality show participants were never at risk of a polar bear attack
Spoiler Alert! Participants of the History Channel’s Season 9 ‘Alone’ and its spinoff, ‘Alone: Frozen’ reality shows were never at risk of a polar bear attack despite the marketing hype claiming they were, because coastal Labrador is only ‘polar bear territory’ when pack ice is present offshore, which it wasn’t when the shows were filmed. Shocking, I know!
I happened upon the trailer for the ‘Alone’ series while watching TV one night and the “set in the hunting territory of the mighty polar bear” claim caught my attention. So I watched a few episodes and did some followup. Before the series even ended, there were ads for the spinoff series, ‘Alone: Frozen’, which had even more polar bear hype. Here’s what I discovered–call it a Frivolous Friday post if you like, but I felt it had to be said.
UPDATE Friday 23 September 2022:
The ‘Alone: Frozen’ series concluded last night without a single sighting of a polar bear or even its footprint near the area. In fact, mention of the possibility of a polar bear attack by the participants ceased after the first few episodes, although the ‘narrator’ continued this fiction as part of the storyline. I rest my case.
Posted onJune 29, 2022|Comments Off on Claim: data exists showing polar bear body condition improves over summer on sea ice
Do polar bears increase their body condition if they stay on the sea ice over the summer? Do they continue to hunt successfully from broken ice in July and early August in areas like Hudson Bay where ice eventually melts out completely? There seems to be an assumption that they do but one polar bear specialists repeatedly claims there is data showing this is the case.
“Anyone saying sea ice at this time of year doesn’t affect polar bears is ignoring research showing their body condition continues to increase through summer if they’re out on the ice.” [Andrew Derocher 28 June 2022]
I would seriously like to know which paper or papers this data appears in but of course, he doesn’t provide that information. Instead, it’s ‘trust me, I’m the expert’.
Posted onFebruary 27, 2021|Comments Off on Local guide says W Hudson Bay bears have recently ‘put on a lot of fat and are healthy’
Canadian polar bear guide Dennis Compayre has spent more than 20 years around Churchill, Manitoba, and his simple words in a 19 February CBC article promoting an upcoming CBC documentary special are clear: Western Hudson Bay (WH) polar bears are currently thriving.

Compayre does not appear to be a global warming skeptic: he seems to accept the prophesy that the future is grim for these bears. However, if he hadn’t I’m certain he wouldn’t have gotten the job as guide for this Nature of Things documentary, hosted by Canada’s ultimate carbon dioxide doom-master David Suzuki. However, he is at least willing to tell the truth about what has been happening over the last four years (the time it took to film this documentary) with WH polar bears. Continue reading

A just-released report on the latest count for the Alaska portion of the Southern Beaufort subpopulation reveals that numbers have been stable since 2010 despite claims the population has continued to decline. However, the study also has a very odd feature: 2012 had the highest population estimate over the decade of 2006-2015 yet also had the lowest survival of all age classes since 2001.

However, what is essentially good news about polar bear health and survival in the Southern Beaufort has so far been glossed over by the media because the report prominently includes estimates of polar bear dens on land in areas of potential oil exploration, a highly politicized topic. Accordingly, the Washington Post (picked up by other outlets) focused a statement in the paper that “long-term persistence of polar bears (Ursus maritimus) is threatened by sea-ice loss due to climate change” and on the denning issue rather than the new population count. As far as I am aware, no other population estimate report has included such distracting information.
Recent claim of a polar bear expert [my bold]:
In 2015…the polar bear population in the Beaufort Sea had declined by 40% over the previous decade. “We can only anticipate that those declines have continued.” Steven Amstrup, 29 September 2019.
Posted onJuly 8, 2020|Comments Off on 10 fallacies about Arctic sea ice & polar bear survival refute misleading ‘facts’
This updated blog post of mine from last year is as pertinent now as it was then: it’s a fully-referenced rebuttal to the misleading ‘facts’ so often presented this time of year to support the notion that polar bears are being harmed due to lack of summer sea ice. Polar Bears International developed ‘Arctic Sea Ice Day’ (15 July) to promote their skewed interpretation of polar bear science at the height of the Arctic melt season. This year I’ve add a ‘Polar Bears and the Arctic Food Chain‘ graphic, which readers are free to download and share. For further information, see “The Polar Bear Catastrophe That Never Happened“.
Posted onJanuary 26, 2020|Comments Off on Activist Norwegian makes more false claims that trophy hunting threatens polar bears
An anti-hunting Norwegian activist-photographer has again made unsupported claims about legal polar bear trophy hunting in Canada and its impact on the survival of the species, promoted by two UK tabloid newspapers (The Sun and The Mirror) over the weekend. The reality is that polar bears are no more being driven to extinction by trophy hunting than they are battling to survive the effects of climate change: they are currently thriving.
According to the Mirror, “Awarding-winning wildlife photographer and conservationist Ole Liodden has warned the iconic Arctic species will die out if trophy hunting is allowed to continue” but no reputable biologist or conservation organization says this, including the IUCN Red List, CITES, the IUCN Polar Bear Specialist Group, or Polar Bears International. This should tell any rational individual that photographer Ole Liodden is misrepresenting the truth to support his rabid anti-hunting stance.
I understand that some people object to hunting (especially trophy hunting) and wish more people felt like they do – but Liodden’s opinion is nothing more than the emotional rant of a conspiracy theorist and should be ignored. Continue reading

Posted onJuly 12, 2019|Comments Off on 10 fallacies about Arctic sea ice & polar bear survival: teachers & parents take note
Summer sea ice loss is finally ramping up: first year is disappearing, as it has done every year since ice came to the Arctic millions of years ago. But critical misconceptions, fallacies, and disinformation abound regarding Arctic sea ice and polar bear survival. Ahead of Arctic Sea Ice Day (15 July), here are 10 fallacies that teachers and parents especially need to know about.

Posted onMay 13, 2019|Comments Off on Polar bear habitat update for early spring shows no influence of a CO2 control knob
The primary feeding period for polar bears is rapidly drawing to a close in much of the Arctic, although it may continue for another few weeks in the farthest north. Mating is pretty much over as well, which means the polar bears’ need for abundant sea ice is declining even more rapidly than the ice does itself at this time of year.
Despite the fact that CO2 levels have now reached 415 ppm (see tweet below), sea ice is still pretty much as it was in 2006 when CO2 was about 385 ppm. In other words, the state of sea ice at this time of year – just over 12 million kilometres squared in 2006 and in 2019 – shows no correlation with rising CO2 levels. There is also not a hint of imminent catastrophe for polar bears anywhere within their range, despite the hand-wringing messages from conservation fear-mongers and their polar bear specialist supporters.
Posted onJune 25, 2018|Comments Off on Hansen’s 1988 climate change testimony was the answer to Stirling’s polar bear problem
Last week’s media coverage made me realize that James Hansen’s testimony to a US Senate committee in 1988provided well-timed answer to a vexatious problem facing polar bear biologist Ian Stirling. Thirty years ago, Stirling was struggling to understand why polar bear productivity in Western Hudson Bay had dropped. He was ripe for the suggestion from Hansen (and his follow-up paper) that human-caused global warming could be the explanation. An interview with Stirling and colleague Andrew Derocher published in 2016 helps connect the dots.
Many bears were in poor condition in the fall of 1983 (Calvert et al. 1986:19, 24; Ramsay and Stirling 1988). In general, the 1980s saw weights of bears decline and cub mortality increase, with a marked increase in the loss of whole litters over what had been documented in the 1960s and 1970s (Derocher and Stirling 1992, 1995).
Until Hansen and climate change came along, density-dependent effects (such as the number of bears out-pacing food supply) were seen as the most likely explanation. But sea ice decline blamed on human-caused global warming was suddenly a new possibility that Stirling soon embraced (Stirling and Derocher 1993). By the late 1990s, sea ice coverage on Hudson Bay had indeed declined but the correlation with polar bear productivity produced a weak trend that was not statistically significant (Stirling et al. 1999).
The 1999 Stirling paper did not provide scientific evidence to explain the 1980s decline in productivity as much as it presented a novel scapegoat to blame when a more plausible explanation could not be made.
Bottom line: Global warming could not have been the proximate cause of the productivity changes in WH polar bears documented during the 1980s but Stirling spent the next two and a half decades vigorously pushing climate change as the cause of all polar bear ills. Continue reading
