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).

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

This essay explains in simple terms why so many people still believe that polar bears are in peril when nothing could be further from the truth: it is an essential lesson that shatters the basis of the shameful indoctrination of young school children and undermines the baseless claims of activist protestors. It was written and translated into French for a special climate change feature issue (July) of the monthly French magazine Valeurs Actuelles (reviewed here) and reprinted by the French hunting magazine Chasses Internationales. It has also been translated into German for a dedicated climate change issue (11 July) of the Swiss weekly magazine Die Weltwoche.
I have added a couple of figures to illustrate this English version of the essay.

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 status since 1991.
Details from the 3 December 2018 press release below.
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.
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 in its 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.
My new report reveals that polar bears are doing well despite recent reductions in sea-ice. It shows in details why this is so, with summaries of critical recent research.

My “State of the Polar Bear Report 2017” will be unveiled at a Global Warming Policy Foundation press conference and luncheon in Toronto on Tuesday, 27 February, in celebration of International Polar Bear Day. There will be a video presentation as well.
The report summarizes clear, reliable and concise information on the current state of polar bears relative to historical records. It highlights up-to-date data and research findings in a balanced and factual format that avoids hype and exaggeration, all in one place. It is intended for a wide audience, including scientists, teachers, students, decision-makers and the general public interested in polar bears and Arctic ecology.
The launch will be held on Tuesday 27 February at 11:00am at the Toronto Public Library, Founders’ Room, 789 Yonge St, Toronto, ON M4W 2G8.
* Welcome (Dr Benny Peiser, Director of the GWPF)
* Introduction: Prof Chris Essex (Chairman of the GWPF’s Academic Advisory Council)
* Short video screening
* Presentation: Dr Susan Crockford (author of the report)
For further information and to schedule interviews, please contact Harry Wilkinson (firstname.lastname@example.org)
A copy of the report will be posted on Polar Bear Science Tuesday.

In scanning comments generated by the recent flurry of internet interest in polar bears and blogs I noticed that a good many people, fed alarming media stories, are still convinced that polar bear numbers are declining rapidly when nothing could be further from the truth.
