Flashback Friday: The Politics of Polar Bears CBC documentary from 2014

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.”

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.

IUCN polar bear specialists reject IPCC- supported forecasts of sea ice based on CO2

In case you missed it — or missed the significance of it — polar bear specialist Mitch Taylor correctly pointed out in his recent essay (a response to the New York Times article that appeared Tuesday (10 April) about the Harvey et al. (2018) BioScience paper) that the IUCN Polar Bear Specialist Group have given up using computer models of future sea ice extent based on rising CO2 levels supported by the IPCC.

Their latest assessment (Regehr et al. 2016) does not link polar bear survival models to climate modeled forecasts of Arctic sea ice decline but rather to an assumption that declines already documented will continue in linear fashion over this century.

This means that CO2 emissions blamed on human fossil fuel use is no longer directly tied to the predicted future decline of polar bear numbers: IUCN polar bear specialists simply assume that sea ice will continue to decline in a linear fashion with no cause attributed to that decline except the broad assumption that anthropogenic climate change is to blame for Arctic sea ice declines since 1979.

No wonder former USGS polar bear biologist Steve Amstrup never refers to this IUCN PBSG study: he and the organization that now employs him, Polar Bears International, are still firmly wedded to the concept that CO2 is the sea ice control knob.

Polar bear specialist Mitch Taylor on accountability in polar bear science

Polar bear specialist Mitch Taylor emailed me and others his response to the New York Times article that appeared Tuesday (10 April) about the Harvey et al. (2018) BioScience paper attacking my scientific integrity. Here it is in full, with his permission, and my comments. Don’t miss the footnote!

Death of the polar bear as climate change icon validates Mitch Taylor’s skepticism

You could call it karma — the death of the polar bear icon after the shameful hubris of polar bear experts back in 2009.

That year, the IUCN Polar Bear Specialist Group booted 20-year member Mitch Taylor out of their organization, explaining that his skeptical views on human-caused global warming were “extremely unhelpful” to their polar bear conservation agenda.

Said chairman Andrew Derocher in his email to Taylor:  “Time will tell who is correct.”

It’s now clear that Mitch Taylor was right to be skeptical of sea ice models based on pessimistic climate change assumptions; he was also right to be more optimistic than his PBSG colleagues about the ability of polar bears to adapt to changing sea ice conditions (Taylor and Dowsley 2008), since the bears have turned out to be more resilient than even he expected.

Fat polar bears — not starving ones — dominate photos taken in recent years. The total failure of polar bear numbers to crash as predicted in response to the abrupt decline in summer sea ice in 2007 and persistent low summer sea ice levels since then (Crockford 2017), is vindication for Mitch Taylor. It’s time someone said so.

More on the 2009 incident below.

Both sides now: New paper critiques Canadian polar bear population status

Demographic and traditional knowledge perspectives on the current status of Canadian polar bear subpopulations. 2016 (in press). Jordan York, Martha Dowsley, Adam Cornwell, Miroslaw Kuc and Mitchell Taylor. Ecology and Evolution 6(9):2897-2924. DOI: 10.1002/ece3.2030

York et al 2016 fig 1_numbers 2013

Take home quote:

“We see reason for concern, but find no reliable evidence to support the contention that polar bears are currently experiencing a climate crisis. We suggest that the qualitative projections for dramatic reductions in population numbers and range are overly pessimistic given the response of polar bears, climate, and sea ice to the present.”

Polar bear doom and gloom from USGS vs. biologist Mitch Taylor’s reasoned thoughts

A few days ago polar bear biologist Mitch Taylor and Nunavut’s Gabriel Niryungaluk talked to Toronto radio host Roy Green about the recent USGS dire model predictions for the future of polar bears.

Andrew Derocher raises the “starving polar bears” issue in DailyMail interview

In what looks like a follow-up to last week’s CBC documentary, The Politics of Polar Bears, the London (UK) based DailyMail published interviews with polar bear biologists Mitch Taylor and Andrew Derocher (September 9, 2014).

The CBC film did have a one scientist vs. another” flavor about it and this article definitely echoes that approach. My comments below on Derocher’s insinuations and questions about starving bears and global warming.

“The Politics of Polar Bears” lengthy excerpt airs across Canada – cue the outrage

Umbrage alert! Last night, a half-length short form of the powerful and balanced documentary “The Politics of Polar Bears” aired across Canada on the CBC’s flagship TV news program, The National.

Has the tide turned on polar bears as icons of global warming?

The CBC in Canada is pretty much a mirror image of the BBC in the UK, ABC in Australia and PBS in the US. So you might appreciate my shock at the almost unbelievable balance contained in the recently broadcasted CBC documentary, “The Politics of Polar Bears: Tracking the Celebrity Bear.

The film is a profound change from the hype and pessimism that has dominated the polar bear issue in Canada and abroad, supported unchallenged by the CBC. Finally, TV viewers were given some decently balanced perspective on the status of polar bears in  Western Hudson Bay.

If the take-away message tipped towards reason and optimism rather than panic over the status of polar bears, it’s because the evidence was strongly in that direction.

Must watch – “The Politics of Polar Bears: Tracking the Celebrity Bear”

This powerful, balanced documentary, with a focus on the bears of Western Hudson Bay, can now be watched online. A Canadian Broadcasting Corporation (CBC) production, it includes interviews with polar bear biologists Mitch Taylor (screen-cap below) and Seth Stapleton – juxtaposed with statements from outspoken polar bear conservation advocate Andrew Derocher.

I was not mentioned by name (making me “she who cannot be named” yet again?) but host Reg Sherren did discuss the contents of the email I received from PBSG chairman Dag Vongraven earlier this summer about their proposed clarification to the global population estimate (and posted here).

It can be viewed online at “CBC Player,” in its entirety (45 minutes long), without commercials – see it http://www.cbc.ca/player/Shows/Shows/Absolutely%20Canadian/Absolutely%20Manitoba/ID/2499492515/?cmp=rss

I can’t guarantee those outside Canada will be able to view it but I watched it Sunday night (August 31) from British Columbia. It’s well worth the time.
