Here I take a detailed look at sea ice and polar bear population health information available for Western Hudson Bay and the Southern Beaufort compared to the Barents and Chukchi Seas. Data from the first two regions – but especially Western Hudson Bay – are used repeatedly to proclaim that a pronounced decline in summer sea ice since 1979 has caused harm to the health of global polar bear populations even though data from the second two regions strongly contradict such a conclusion, as I’ve pointed out in my fully referenced book, The Polar Bear Catastrophe That Never Happened.
These contradictions mean that studies from Western Hudson Bay and the Southern Beaufort should not be used to extrapolate to the rest of the Arctic with regard to how polar bears are responding to reduced summer sea ice. The plea to ‘Save Our Sea Ice‘ for the sake of polar bear survival is a climate change marketing slogan, not a scientific assessment.

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):

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.

Misplaced eco-anxiety that kids have about polar bears starts with activist biologists like Steven Amstrup, spokesperson for an organization devoted to raising climate change alarm – and media outlets like The Guardian who help them spread fears unsupported by scientific evidence.

You can’t get much more over the top than these statements from Amstrup today but read carefully: it’s either opinion or factual aspects of polar bear life (“we know that the bears aren’t feeding”) made to sound like new, terrifying developments that can be blamed on climate change.

Since at least 2007, zoos around the world have proudly partnered with climate change activist organization Polar Bears International to ‘educate’ the public about the plight of polar bears. Although contrary to all expectations, polar bear numbers have increased slightly since the abrupt decline of sea ice in 2007 yet zoos are still promoting the false message that polar bears have already been gravely harmed by lack of sea ice.
A news clip that aired on Canadian television in April 2019 was ostensibly about recent sightings of polar bears in Labrador (which I discussed here). But it digressed rapidly into a baseless diatribe about polar bears as victims of climate change, delivered by an animal keeper from the Toronto Zoo presented as an ‘expert’ on this topic.
See it here (about 4 minutes long).
And while I have no doubt that Toronto Zoo curator Maria Frankie is indeed an expert in keeping mammals in captivity, she appears to have zero qualifications to speak with any critical scientific authority on climate change, sea ice variability, or polar bear survival in the wild.
Frankie is complicit in spreading misinformation about polar bears to an unwary public (including children) as a method of spurring political action on climate change as surely as David Attenborough is to blame for spreading misinformation about Pacific walrus. She is being used by PBI but is too naive to realize it.

According to Harvey and colleagues (2017), any internet posting that discusses polar bears without a link to PolarBearScience or a mention of my name can be considered a ‘science-based’ blog. But they missed an obvious catch: bloggers who use my content without attribution.
For example, so-called ‘science-based’ blog Churchill Polar Bears, written by Churchill polar bear guide Steve Seldon, used text and two of the four figures provided in a 15 February 2017 post at PolarBearScience to create a Churchill Polar Bears post on 17 February but did not include a single link to PolarBearScience indicating that’s where he got his information (Wayback machine link here).
A few would not consider this plagiarism but most do. That is to say, failure to attribute a source when work or information is not your own is a big no-no in science, as it is in all of academia.
Consider this evidence: Continue reading
Guess which year between 2006 and 2016 had the latest start to freeze-up on Hudson Bay, given that 2012 had the lowest September average and 2007 and 2016 tied for second-lowest (see graph below, from NSIDC), and that sea ice in the Arctic right now is the lowest it’s been for this date since 1979?
If you guessed anything other than 2010, you guessed wrong – in addition, 2006 (not 2016) was second latest.
There is no correlation between Arctic sea ice coverage and freeze-up dates for Western Hudson Bay.
Yet, Polar Bears International (“Save Our Sea Ice”) – who were surely in and around Churchill in 2010 and 2006 watching polar bears – just posted an alarming statement about local conditions, implying that slow freeze-up of Hudson Bay this year is a reflection of the fact that “sea ice is at a record low across the Arctic.”
They also claim that “…the weather is the warmest we’ve ever seen at this time of year.” That may be true, but if so, it is also meaningless with respect to the progress of freeze-up.
Does no one at PBI remember the very late freeze-up of 2010 or 2006? Odd, that.

CBS News published a predictably one-sided “Cover Story” this morning (14 February 2016) about Churchill, Manitoba – the self-proclaimed Polar Bear Capital of the World.
This is the online version of a Sunday morning TV special that’s not available where I live. It’s yet another example of how the media feeds the politics of polar bears and prevents the advancement of science. Here’s my take on this CBS effort.

Media outlets have recently been having collective orgasms over photos and videos of a three month old polar bear cub born at the Columbus Zoo in Ohio, which has again raised the issue of why it is now acceptable for polar bears to be held and bred in captivity.

The myth being propagated by zoos and their supporters is that it’s necessary to save polar bears from extinction.
Actually, nothing could be further from the truth – this is all about pressuring people to care about climate change. Polar bears are merely a marketing tool to spur action on climate change. That’s not my opinion but the plan put in place in 2012 by the Association of Zoos and Aquariums and Polar Bears International.
Oddly, few animal rights activists are objecting (or at least, not objecting very strenuously) to zoo displays of captive polar bear cubs – obvious money-making draws for zoos – which were so vehemently condemned in the 1970s that most zoos gave them up.
Now, the practice is defended and everyone seems to feel this is the greatest thing since the invention of the telephone. [Update 19 February 2016: courtesy the BBC, we can add Highland Wildlife Park in Scotland to the list of zoos using “we’re saving the polar bears” justification for breeding the bears in captivity]
The surprise is that disgraced climate scientist Michael Mann, promoter of the infamous hockey stick of global temperatures, is involved in all this.

You have to know that the 2015 IUCN Red List assessment for polar bears contains good news because no one is talking about it – and none of the online information sources I’ve checked have updated their polar bear profiles to reflect it.
For all its flaws (including the deceptive focus on summer sea ice), this Red List update is the most statistically robust, in-depth study of the conservation status of polar bears – why is it being ignored, especially by the conservation organizations people turn to for information online?
UPDATE: see 18 January 2016 post here.
