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 a report by CBC News earlier this week (18 February 2019), there was a defence kill of a potentially dangerous polar bear and her cub in Foxe Basin, Nunavut on January 4th that we are just hearing about now. Yet another bear on shore in winter, when there is plenty of sea ice, looking for food in an Arctic community and threatening the lives of its residents while a polar bear specialist blames such incidents on lack of ice.

A part-time Arctic researcher eager for media attention suggested earlier today that the ice entrapment of narwhals in 2008 and again in 2015 at Pond Inlet (that made headlines around the world) was the result of “sudden changes in temperature” caused by climate change. This grossly misleading claim ignores the facts: ice entrapment of narwhals is an entirely natural feature of the Arctic that has been known about for hundreds of years.
“Narwhals: the ‘giant unicorn of the sea’ at risk from climate change” (CBC, 13 August 2016), a print version of a CBC Radio interview with Clint Wright that aired 8 August 2016. Wright is the general manager at the Vancouver Aquarium and apparently has “joined a team of researchers to tag and study” narwhals for several years – but does not seem to know much about the history or circumstances of natural ice entrapment.
Ice entrapment of small whales is nothing new. The first formally documented incident – in English – occurred in 1915 (Porsild 1918) and the phenomenon has probably occurred as long as there has been ice in the Arctic (millions of years).
Animals routinely become trapped in a few specific areas due to local geography: when ice that forms in the north moves south quickly, it blocks the entrances to inlets or coastal bays that still have open water. The presence of the pack ice causes nearby temperatures to drop quickly. Rapid development of ice on the bay proceeds from the mouth toward the head of the bay. Any whales present cannot escape to open water and will eventually die or be eaten.
Pond Inlet at the north end of Baffin Island is one such place but Disko Bay in western Greenland is another. In fact, Pond Inlet and Disko Bay are almost identical in geographic layout even though they lie on opposite sides of Baffin Bay, so it’s not surprising that both are locations of repeated entrapment events.
Three highly informative journal articles on the phenomenon of ice entrapment of narwhals and beluga are open access documents that reveal some fascinating details of such incidents, including polar bear predation on trapped whales. h/t T. Nelson Continue reading

There is still below average ice extent in the Barents Sea but there is no data whatsoever to indicate that this situation poses a problem for polar bears, given that as far as researchers know, polar bears eat little or nothing during the winter. That’s why the bears are at their leanest at the end of winter and why seal pups born in early spring are such a critical food source.
Note on map below (from WUWT Sea Ice Page, marked; original here) that polar bears are not found in three areas that are included in the total Arctic ice extent figures: below-average or above-average ice in the Sea of Okhotsk, Baltic Sea, and Gulf of St. Lawrence have no impact on polar bear health and survival.
