Posted onAugust 25, 2022|Comments Off on Inuit are concerned about public safety as Davis Strait polar bears numbers increase
An assessment of the health of Davis Strait polar bears by 35 Inuit polar bear experts was made public two weeks ago. Overall, these experts agree that virtually all polar bears they see are healthy and that the population has been growing over the past few decades, so much so that “public safety has become an increasing concern”. Mainstream media have ignored this report, as far as I have seen.
As we await the latest scientific population estimate of Davis Strait polar bears, completed in 2021 but still not publicly available (only a preliminary gov’t report and a summary graphic from the final report have been released, see Dyck et al. 2019, 2021) this new document (Tomaselli et al. 2022) provides the essential information we need. Polar bears are doing well with no notable changes in cub numbers or survival in the last few decades, abundance is up and reflects a real increase in numbers. There are so many polar bears that communities and individuals feel the need to take extra precautions in protecting themselves from bears.
Oh, and ringed seal numbers are way down: that could be a critical bit of information we won’t get from the polar bear academics.
Posted onMay 10, 2021|Comments Off on How are polar bears doing 15 years after the IUCN declared them ‘vulnerable’ to extinction?
The beginning of this month was the 15th anniversary of the day the IUCN declared polar bears ‘vulnerable’ to extinction because of climate change, the first time such a designation had ever been made. It was based on the opinion of polar bear specialists who examined the vague information available at the time and decided that in 45 years the bears might be in serious trouble. This decision changed the way the IUCN assessed species risk and led to mass confusion for the general public, who falsely assumed polar bear numbers had already declined by a huge amount.

“Polar bears continue to be described as ‘canaries in the coal mine’ for the effects of human-caused climate change, but the evidence shows they are far from being a highly-sensitive indicator species.” Susan Crockford, 24 February 2021
You’ll find the evidence I allude to above – backed up by references to the peer-reviewed literature – in my many publications (Crockford 2015; 2017; 2019, 2020, 2021). My open-access research paper from 2017 has been downloaded more than 6,000 times and despite this being an online forum for legitimate scientific critique, none has been offered. My comprehensive polar bear science book released just two years ago (see below) has a 4.7/5.0 star rating on Amazon, with 132 reviews so far.
For recent blog post examples of the evidence that polar bears are thriving despite profound summer sea ice loss, see this discussion about the many contradictions that exist for claims that sea ice declines have caused harm to polar bear health and survival and this review of the evidence that less summer sea ice has meant more food for polar bears.
Posted onApril 29, 2020|Comments Off on New report: Change coming to the Canadian Arctic — but it’s no looming catastrophe
A review of a newly-released (22 April 2020, on Earth Day) report commissioned by Canada’s Department of Fisheries and Oceans on the state of the Arctic seas published today in the National Post is a must read. It highlights the report’s emphasis that while the changes going on in our northern seas are indeed marked, they do not necessarily spell doom.
Oddly, polar bears are primarily represented in the report by an overview account of the special case of Western Hudson Bay – an outlier among Canadian subpopulations – that puts special emphasis on the claimed decline in body condition blamed on recent sea ice changes that is not supported by any recent data (Crockford 2020).
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 onApril 23, 2019|Comments Off on Even with Inuit lives at stake, polar bear specialists make unsupported claims
The standoff between Inuit and polar bear specialists regarding the status of polar bears in Canada is not going to end until someone in authority demands to see the data scientists insist contradict Inuit knowledge.
An article in Maclean’s Magazine (15 April 2019), entitled “To Kill a Polar Bear”, explores some of the feelings and opinions of folks involved but fails to ask whether the data support the rhetoric advanced by scientists. Author Aaron Hutchins takes the scientists at their word, that seeing more bears than 20 years ago is all because of lack of sea ice. However, from what I’ve seen, he might as well trust a fox in a hen house.
Ian Stirling is quoted by Hutchins insisting that polar bears in Western Hudson Bay continue to suffer from the effects of declining sea ice, without mentioning that ice cover has been essentially static on Hudson Bay since at least 2001 (Castro de la Guardia et al. 2017; Lunn et al. 2016) and fall freeze up dates for the last two years were earlier than most years in the 1980s:
“This year saw the seventh-lowest Arctic sea ice levels since the National Snow and Ice Data Center ﬁrst started gathering satellite data 40 years ago, with the long-term trend clearly downwards. And the negative effects on polar bears can be clearly seen in the science, says Stirling, pointing to the closely studied subpopulation along western Hudson Bay: “They’re losing body condition. Reproductive rates have dropped. Survival rates of young have plummeted. Every indication you would expect from a declining population is there.”
However, as I’ve pointed out previously (last year and in 2012), there are no recent data published that support these claims: the only information that exists is at least 25 years old. And the fact that no such data have been published suggests strongly that it either does not exist or does not show what Stirling claims it shows.
Yet, the government of Canada is willing to bet the lives of Inuit on their belief that polar bear specialists would never stretch the truth to qualify for government grants.

At recent meeting of the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), biologists decided to continue to list the polar bear as a species of ‘Special Concern.’ About 2/3 of the world’s polar bears live in Canada and the balance of all evidence (including Inuit knowledge) indicate the bears are not threatened with extinction. The bears have held this statussince 1991.
Posted onJune 11, 2018|Comments Off on Environment Canada maps of polar bear population and status assessments 2018
Just out (6 June 2018) — new population assessment and status maps of the 19 polar bear subpopulations according to Environment Canada. Contrary to the map presented at the Range State meeting in February 2018 (pdf here), these maps show Western Hudson Bay and Southern Hudson Bay (along with the Southern Beaufort) as “likely declined.” A new category has been added for the Barents Sea: it’s considered “data deficient/uncertain,” but a population estimate of 2,001-3,000 has been provided.
No press release or other notice regarding the availability of these new maps was issued, as far as I know: I came across them by accident while looking for something else.
Global map above, more below, including a comparative map that shows 2010, 2014, and 2018 together. I will update the two recent posts of mine (here and here) that used the February Range State map with the information that more recently revised maps are now available.
Posted onMay 24, 2018|Comments Off on Status of Canadian polar bears updated map from Environment Canada
During a meeting of polar bear range states (Canada, Russia, Greenland, Norway, and the USA) in late January 2018 to discuss conservation issues, Canada — home to ~2/3 of the world’s polar bears — included inits presentation an updated population status and trend map approved by the Polar Bear Technical Committee in its presentation. This 2017 map replaces one from 2014 but is not yet available on the Environment Canada website.
UPDATE 11 June 2018:More recent versions of population and status assessment maps, published by Environment Canada 6 June 2018, conclude Southern Hudson Bay and Western Hudson Bay subpopulations have “likely declined.” See 11 June post here for more details and copies of the maps.
