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.

Politics of polar bears title

“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.

More starving polar bear nonsense from National Geographic & a better video to watch

This time National Geographic’s ‘Hostile Planet’ series laughably claims a fat polar bear that’s caught a beluga calf off the coast of Western Hudson Bay has been saved from starvation! The message: here is a prime example of climate change pushing a species to its limit. This is nonsense, of course: polar bears hunting beluga whales from rocks has nothing to do with climate change or desperately hungry bears. More importantly, there is a much better video of the action that is both more informative and truthful.

CBC hypes “bleak” Churchill polar bear fate with unsupported claims & falsehoods

Over the weekend in Canada, the CBC ran a polar bear news feature that is now available online (“Polar bears in peril: the bleak future of Churchill bears,” The National, CBC, 3 December 2018). It gave polar bear biologist Nick Lunn of Environment Canada free rein to spread unsubstantiated claims and outright falsehoods about the status of Western Hudson Bay polar bears and sea ice. Apparently, he and the CBC learned nothing from National Geographic‘s fiasco over their starving’ polar bear video last year: they still think the public will be swayed to “act” on human-caused global warming if a persuasive expert tells them that polar bears are on their way to extinction. I expect many were convinced otherwise, since the facts are available for all to see.

No triplet litters born since 1996? Nonsense, as the photo below (from 2017) shows.

The CBC video is described this way:

“They are a majestic icon of Canada’s North, but polar bears have also come to symbolize climate change. And scientists say the future for one particular population of polar bears in northern Manitoba is dire.

W Hudson Bay freeze-up one of earliest since 1979, not “closer to average”

Tundra Buggy Cam_10 Nov 2017_bear headed offshore pmWestern Hudson Bay polar bears have been leaving shore for the rapidly thickening sea ice since at least 8 November (bear above was heading out 10 Nov.). However, Polar Bears International chose not to mention the unusually early freeze-up until the week-long (5-11 November) doomsday bombardment they call “Polar Bear Week” was almost over.

It’s worse than that: two days earlier, PBI’s activist spokesperson Steven Amstrup apparently told the Sierra Club (“People Show Up for Polar Bear Week, But the Ice Hasn’t Yet”; 8 November 2017) that “the bears are still waiting on shore for that ice to freeze” even though ice development had been well on its way for days at that point. As if freeze-up on 10 November came as a big surprise to him, with no warning whatsoever.

Apparently, they didn’t want their naive and gullible supporters to know at the beginning of Polar Bear Week that the sea ice loss of which PBI spokespeople rant about constantly (Save Our Sea Ice) was a total non-issue this year: breakup was not earlier than usual and new ice began developing off Churchill at about the same time it did in the 1980s (last week of October).

As I discussed last year regarding newly-published studies (Obbard et al. 2015, 2016) on the status of Southern Hudson Bay (SHB) bears:

“…SHB polar bears left the ice (or returned to it) when the average ice cover near the coast was about 5%. This finding is yet more evidence that the meteorological definition of “breakup” (date of 50% ice cover) used by many researchers (see discussion here) is not appropriate for describing the seasonal movements of polar bears on and off shore.”

That post (with its list of references) is worth another look for its discussion of the following points: the definition of freeze-up; the relationship of official freeze-up and breakup dates to the dates that bears depart; the overall health and survival of Western and Southern Hudson Bay polar bears.

Below I dissect the misinformation that PBI calls “science communication” in their attempt to minimize the damage caused by this early freeze-up to their message of looming catastrophe for polar bears.

Bottom line: Not only was freeze-up early this year, 2017 will go down as one of the earliest WHB freeze-up years since 1979 and for Southern Hudson Bay bears as well, since as of 13 November there is concentrated ice all the way into James Bay.

Sea ice Canada 2017 Nov 13

UPDATE 14 November 2017: CBC Radio broadcasted an interview yesterday with a recent visitor to Churchill who was remarkably candid about what he saw regarding polar bears, sea ice, and what he heard from locals about freeze-up (“the earliest since 1991”). It corroborates what I’ve reported here. Worth a listen (about 8 minutes):

“Brian Keating: Polar bears in Churchill, Manitoba” (The Homestretch, November 13, 2017, Season 2017, Episode 300312418)

The closest Doug Dirks has come to seeing a live polar bear was at the Calgary Zoo many moons ago. But naturalist Brian Keating has just returned from another trip to Churchill, Manitoba. He joined Doug Dirks with the details of that frosty adventure.

Still lots of East Coast sea ice but prof tells CBC it doesn’t bode well for polar bears

Davis Strait polar bears around Newfoundland and Labrador are currently experiencing what one polar bear specialist refers to as “failed” sea ice conditions, causing bears to come ashore in droves. I’m not making this up.

Sea ice extent Canada 2017 April 21 CIS

The ice was so thick in the Strait of Belle Isle between Newfoundland and southern Labrador last week that a ferry was stuck for 24 hours and had to be rescued by an icebreaker.

The boats of fisherman on the north shore of Newfoundland are stuck in thick ice that’s not expected to clear until mid-May at the earliest and they can’t get out to fish.

boats-in-ice-near-twillingate_CBC_19 April 2017

See this video posted on Twitter two days ago.

The same thing (perhaps even worse) happened in 2007, see Twillingate in the spring of 2007 below:

Twillingate-heavy ice-20070523_2007 CBC David Boyd photo

Yet, in 2007 there was not a single polar bear reported onshore in Newfoundland (as far as I am aware) but this year there were almost a dozen. And the photos show fat, healthy bears – not animals struggling to survive.

According to Andrew Derocher, that’s proof “failed” sea ice is the reason that polar bears came ashore this year but not last year (when there was also lots of ice in late March/early April, see additional maps and graphs below). Last year there were sightings in the middle of winter (January/February) in Labrador and Newfoundland (which I reported here) and one bear was shot in Newfoundland in early May when he advanced on local RCMP officers.

I think Derocher believes he’s set the record straight by offering an interview of his own to refute the things I said to the CBC last week (I talked on two Newfoundland radio stations, which generated a print CBC article). But Newfoundlanders have to deal with used car salesmen just like the everyone else, so I expect they are having a good laugh right now at the expert who’s blaming their polar bear troubles on a lack of sea ice.

Another alleged grizzly-polar bear hybrid shot but it’s not a sign of climate change

CBC News this morning (“Grolar or pizzly? Experts say rare grizzly-polar bear hybrid shot in Nunavut: Expert says interbreeding may be happening more frequently due to climate change“) suggests that a putative grizzly x polar bear hybrid bear shot outside Arviat in Western Hudson Bay is a sign of climate change, based on an interview with a black bear expert from Minnesota.

This bogus claim has been busted so many times it’s a wonder it still arises – even polar bear specialist Ian Stirling has said flat out that such hybrids are not due to climate change. On top of that, some of the details regarding this putative hybrid make me want to wait for confirmation from DNA testing before adding it to the roster of known hybrids.

In 1999, climate change apparently threatened Western Hudson Bay polar bears

Now, not so much. Here is a 16- year old CBC TV special on Churchill polar bears – listen to Ian Stirling and reporter Eve Savory use the early breakup of sea ice on Hudson Bay in 1999 to hype the alarm about Western Hudson Bay polar bears. Watch Stirling in action darting and measuring bears and bemoaning the good old days of the 1980s, claiming the “bears are sending a signal from the ecosystem.

Watch this archived copy of “The Shrinking Bears of Hudson Bay and compare his claims to what has actually happened in the 16 years since then. It runs just over 15 minutes.

Climate change threatens polar bears 2_CBC 1999

“Just as the ice is shrinking in Hudson Bay, so are its polar bears. Climate change has shortened the season for winter ice, a crucial period for the bears to feast on seals and build up their fat reserves. And so, over the 18 years that wildlife biologist Ian Stirling has been studying them, the polar bears have become skinnier and their offspring fewer. In this 1999 report for CBC-TV’s The National, Stirling says once their habitat is gone, there’s nowhere else the Hudson Bay polar bears can go.” [my bold – see notes below]

Program: The National [Canadian Broadcasting Company, CBC]
Broadcast Date: Sept. 23, 1999
Duration: 16:39

Stirling has continue to make these claims since 1999, yet no updated evidence has been provided. There is no plausible evidence that the decline of polar bear numbers in Western Hudson Bay was due to sea ice changes caused by human-caused global warming (Crockford 2015) or that continued declines in condition of bears or litter size have  occurred. Note that the latest survey of Western Hudson Bay polar bears found no trend in either breakup or freeze-up dates since 2001 (Lunn et al. 2013) and that the population is now stable.

Well-fed polar bears onshore at height of summer easily deterred by noise, CBC reports

From the CBC this morning, we have the report of a female polar bear and her cub paying a visit to an Nunavut campsite near Chesterfield Inlet in northwestern Hudson Bay, which is technically within the boundary of the Foxe Basin polar bear subpopulation.

These are not the desperate bear victims of global warming we have been warned about by polar bear specialists but well-fed curious ursids not averse to an easy meal if there’s one to be had. Such bears are easily deterred by a loud noise. Note this was the second visit by polar bears this Nunavut family had experienced at this location within a three-week period – two other bears had stopped by earlier. Note that ice in this region of Hudson Bay broke up earlier than usual this year yet these bears seem to be in fine condition and can expect the first fall ice of the season (freeze-up) to appear in their neighbourhood, see maps below.

Polar bear habitat update – even more ice this week in the Barents Sea

Polar bear habitat is close to average for this date all over the Arctic this week. Barents Sea pack ice has increased substantially since last week and the ice in Eastern Canada is still well above average (and higher than 1979-early 1980s). Arctic ice has grown since a preemptive call for “the lowest maximum extent on record” was made by NSIDC last week — there is now at least as much ice for this date as there was in 2011 and almost as much as there was last year (2014).

Polar Bear Breaks Ice

Southern Davis Strait polar bears are out feeding on the glut of harp seals in the pack ice off Labrador and Newfoundland (discussed in detail here). One or more bears strayed a bit from the pack and ended up swimming around near the Hibernia oil platform (not far from the ice edge, although the CBC reports didn’t mention that “minor” fact), discussed in this recently updated post (with maps).
