Worth watching if you haven’t seen it – and a second look if you have – a rare balanced documentary produced by the CBC in 2014 on polar bear conservation, with interviews with biologists Mitch Taylor and Andrew Derocher.
“In The Politics of Polar Bears, Reg Sherren will pick his way through the message track to help you decide what is really happening with the largest land carnivore on the planet.”
Short version here (about 18 minutes):
Entire version (45:30):
Online summary by the producer of the film, Reg Sherren (see excerpt below).
The most up-to-date discussion of polar bear numbers and the politics of polar bears are in my popular new book, The Polar Bear Catastrophe That Never Happened.

Arctic sea ice at the middle of winter (January-March) is a measure of what’s to come because winter ice is the set-up for early spring, the time when polar bears do most of their feeding on young seals.
[Mid-winter photos of polar bears are hard to come by, partly because the Arctic is still dark for most hours of the day, it’s still bitterly cold, and scientists don’t venture out to do work on polar bears until the end of March at the earliest]
At 12 February this year, the ice was similar in overall extent to 2013 but higher than 2006.
Word that Russia is planning to generate a count of polar bears along its entire Arctic coast within the next few years is good news indeed, as it will resolve a long-standing gap in population estimates that have not been dealt with at all well by the polar bear community. Whether North American and European academics will accept the results of the aerial surveys is another matter entirely, especially if the numbers are higher than they like, which is what happened with the first Russian Kara Sea count in 2013.
Up first will be the Chukchi and East Siberian Seas in 2021, the Laptev and Kara Seas, in 2022, and the eastern Barents Sea around Franz Josef Land in 2023.

A new paper on Baffin Bay polar bears reports data on body condition and litter sizes collected as part of a major study of the region completed in 2013 compared to sea ice declines since the 1990s; based on a computer model, the authors predict that in 37 years time (if sea ice declines continuously), the incidence of twin litters could “largely disappear.” However, no decline in population numbers was predicted and a critical caveat acknowledges that factors other than changes in sea ice could have affected the body condition and litter size data the authors analyzed, which means the conclusions are scientifically inconclusive.
The last (2013) polar bear population survey of Baffin Bay (SWG 2016) generated an estimate of almost 3,000 (2,826; range 2,059-3,593), which means that regardless of some slight changes in body condition and litter size over the last two decades (which may or may not have been caused by loss of sea ice), there are currently a lot of bears in Baffin Bay.

My newest video released today summarizes the strong polar bear component to the terrorization of the world’s children about climate change, which began for many youngsters in 2006 with the BBC and Sir David Attenborough’s commentaries about the dire future of polar bears – and continues to this day. Kids get their climate change information from watching Attenborough documentaries at home and in school because they are trusted sources of information, but on the topic of Arctic victims of climate change, that trust has been betrayed.
Many children and young adults worldwide, including 16 year old Swedish climate campaigner Greta Thunburg, have been presented with such emotionally-charged and deceptive information about the Arctic through Attenborough’s productions that many have lost hope for the future. These despondent kids, as well as their parents and teachers, need reminding that while summer sea ice has indeed declined over the last few decades, polar bears, walrus, and other Arctic species are thriving (Aars 2018; Boveng 2016; Crockford 2017, 2018, 2019a, b; Kovacs 2016; Lowry 2015; MacCracken et al. 2017; Obbard et al. 2016; Rode et al. 2014, 2018).
Here is the video (13 minutes):
The press release issued by the Global Warming Policy Forum states:
It is the responsibility of teachers and parents to reassure these worried youngsters that polar bears and walrus are not suffering because of sea ice loss blamed on climate change. Children need to be told the truth: that whatever scary stories some biologists come up with about what might happen in the future, Arctic species have demonstrated that they are much more resilient to changes in sea ice than Attenborough’s films suggest.
The GWPF is sending copies of this video to all head teachers of UK schools together with a letter, telling them that they are responsible for the mental health of their pupils and that they have a responsibility to provide their pupils with accurate information about the state of wildlife in the Arctic.
The letter sent to head teachers will include a list of verifiable facts, with references, listed here.
Below is my timeline, with references, and below the references is a list of previous videos on this topic.

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
