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.“

According to maps dated June 2014, Environment Canada (EC) has changed the trend status of several Canadian subpopulations — without any announcement or publicly-available documents explaining the basis of the changes.
Figure 1. Environment Canada’s “Map 4: Series of Circumpolar Polar Bear Subpopulation and Status Trend Maps 2010, 2013 & 2014.” Original here.
And would it surprise you to learn that virtually all of these status changes reveal more good news about polar bears?

The latest polar bear propaganda emanating from The Guardian is unscientific nonsense fed to them by activist Canadian polar bear researchers: “Polar bear numbers in Hudson Bay of Canada on verge of collapse.”
This episode of Goldenberg’s polar bear grandstanding includes a photo caption with a totally unsubstantiated claim that some folks might call a lie:
“Melting ice is cutting polar bears off from their food source in Hudson Bay, and death rates have soared.”
“Death rates have soared”? Where are all the bodies? Show us the starving bears!
In fact, the ice of Hudson Bay melts every summer and always has done. When it does, polar bears go ashore and live off the many inches of stored blubber they put on during their spring feasting on fat baby seals. The last three years, the open-water season has been only about two weeks longer than it was in the 1980s. There has been no steady increase but lots of variability.
Below I dismantle the rest of this transparently political posturing ahead of the international polar bear forum next week.
