The report on the latest population estimate for harp seals off the east coast of North America was released in late March without fanfare and therefore no media attention. This was one of the missing scientific reports mentioned in my State of the Polar Bear Report 2019 released in February (Crockford 2020): results of surveys promised for months or years by early 2020 but not delivered.
Not surprisingly then, we find the report has good news: the population estimate of harp seals in the NW Atlantic has risen to about 7.6 million (range 6.55-8.82) animals (DFO 2020), up from 7.4 million in 2014 (DFO 2014).
Note that the survey was done in March 2017, a low ice year for the Gulf of St. Lawrence (see discussion below) and while this may have resulted in some increased mortality for pups born there, it is also known that many ‘Gulf’ pregnant females will instead have given birth off Newfoundland and Labrador in a whelping region called ‘The Front’. Apparently, these factors were accounted for in the population model.
Harp seal pups born at the Front are an important food for Davis Strait polar bears. This increase in the prey base for Davis Strait polar bears suggests the bear population may have grown substantially since the last survey in 2007 (Peacock et al. 2013; Rode et al. 2012). Davis Strai is the only subpopulation of polar bears officially considered to have ‘likely increased’ at 2018 by Environment Canada. A new Davis Strait population size survey was apparently completed in 2018 but the results are not yet available (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

Tomorrow I will be giving a public lecture in Paris on polar bear conservation success and the spectacular failure of the polar bear survival models used to scare children senseless.
However, while I was in London a few days ago I spoke with James Delingpole, author and columnist at Breitbart who has recently taken to producing podcast and video interviews.
Yesterday, he posted a column summarizing our discussion, with a link to the entire podcast: “WATCH: Canadian Professor Lost Her Job for Telling the Truth About ‘Endangered’ Polar Bears.” Read it here.

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 al 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.

Polar Bear Facts and Myths (for children aged 7 and up) is now avaiblable in Norwegian!
The same day as a glowing review of the Dutch translation of my popular children’s science book appeared in de Telegraaf (front page and all of page 5, 19 November 2018, pdf here), I am thrilled to announce that this important book is now available in Norwegian via Amazon worldwide, including European outlets.
The translation was done by native Norwegian speakers Arve Tunstad and Morten Jødal. In Norwegian the book is called ISBJØRN Fakta og Myter.
Please pass along to your friends, relatives, and colleagues in North America and abroad (calling all Sons of Norway). The English version is still available in paperback and ebook formats. Other translations in French and German are already available: five languages in all, including Dutch.
Details below on the Norwegian version. Continue reading
