Polar bears leaping on the backs of belugas off Seal River, in western Hudson Bay, is being falsely promoted by the BBC’s new “Seven Worlds: One Planet” TV special as an unprecedented effect of climate change.
More specifically, the Daily Mail (30 November 2019) this morning quoted the documentary, narrated by Sir David Attenborough, as saying:
‘This extraordinary behaviour has only been recorded here, in this remote corner of North America, and only in the last few years.’
Poppycock. More climate change hyperbole from Attenborough’s seemingly never-ending litany of nonsense that’s easily refuted. There is scientific literature documenting such behaviour in Canada’s far north in the 1980s, which I included in the blog post I wrote about this phenomenon a few months ago (after National Geographic published a similar scare-story), which I have reposted below.
And from the sounds of it, there was no mention in the BBC special that freeze-up along western Hudson Bay was early again this year: for the third year in a row. So if the footage was filmed any time since 2017, the claim of accelerating sea ice loss in this region and bears on land for longer than ever is pure fantasy. PS. Fat bears are not ‘starving’.

This is the third year in a row that freeze-up of Western Hudson Bay (WH) ice has come earlier than the average of 16 November documented in the 1980s. Reports by folks on the ground near Churchill confirm polar bears are starting to move onto the sea ice that’s developing along the shore after almost 5 months on land. After five good sea ice seasons in a row for WH polar bears, this repeat of an early freeze-up means a sixth good ice season is now possible for 2019-2020.
Sadly for the tourists, however, it means the polar bear viewing season in Churchill will be ending early this year, just like it did last year and the year before.

When mothers with cubs are out on the ice (see photo above), it’s pretty certain the mass movement from land to sea ice is well underway because these family units are usually the last to leave.
UPDATE 19 November 2019: Polar Bear Alert report for 11-17 Nov (week 20) confirms that freeze-up is underway, bears are heading out on the ice and problem bears held in the ‘jail’ were released 13 November. See below.
Polar bear researcher Andrew Derocher says it takes four years of good sea ice conditions to recruit a polar bear from birth but implies that 2019 is the first year in decades that conditions for bears have been ‘good’ in Western Hudson Bay. He thinks he can get away with saying this because he hasn’t published any of the data on body weight and body condition he’s collected on these bears over the last 25 years (apparently, whatever funding agency pays for his research does not require him to publish the data he collects).
But independent observations such as dates of ice freeze-up in fall, ice breakup in summer, dates and condition of bears recorded onshore, suggest he’s blowing smoke: at least five out of five of the last sea ice seasons for WH bears have been good. That means we should be seeing more bears in the next official population count.

Polar bear habitat update for the first week of August 2019 shows there is still more sea ice than average in Hudson Bay, the southern-most area of continuous habitation for this species. That certainly wasn’t part of the predictions of doom, especially since freeze-up in that region for the last two years has also been earlier-than-average which means a shorter ice-free season than we’ve seen for decades.
Despite ice coverage for the Arctic ice as a whole being marginally lower than it has been since 1979 for this time of year, sea ice for the first week of August was also above average around Svalbard in the Barents Sea and higher than the last few years in the Central Arctic, which is a critical summer refugium for polar bears that live in the peripheral seas of the Arctic Ocean, including the Chukchi (see photo below, taken in early August 2018).

For all the hand-wringing over sea ice extent this year and its supposed similarity to 2012, what is truly remarkable is that at the end of July ice remains adjacent to every single major terrestrial summer refugia known to be important for polar bears. Those refugia sites include (from west to east, starting in the Chukchi Sea): Wrangel Island, western Chukotka, Severnaya Zemlya, Franz Josef Land, East Greenland, virtually all the islands of the Canadian Arctic Archipelago (including Southampton Island in Foxe Basin and the southwest and eastern coasts of Baffin Island), and Western Hudson Bay.
Few bears spend the entire summer onshore along the Alaska coast: most still spend the summer on the sea ice and move with it as it contracts toward the Arctic Basin, as do many bears in the Barents, Kara, East Siberian, and Chukchi Seas. Until a few weeks ago, however, there was enough ice present that Beaufort Sea bears could go ashore if they wanted to do so. Continue reading

In the course of a manhunt for two murder suspects wanted in British Columbia, Royal Canadian Mounted Police posted a photo of a fat polar bear they spotted about 200 km north of Gillam, Manitoba.
This fat bear – as would any others that might be spotted in the area – is a pregnant female from the Western Hudson Bay subpopulation intent on finding a secure place to dig a den in the permafrost where she can stay cool over the summer and give birth this winter.
However, true to form, The Guardian (28 July 2019) ludicrously suggests those on the hunt for the murder suspects are now at risk of a polar bear attack:
The threat of a polar bear attack has become a reality for the huge Canadian police and military contingent searching for the teenage duo suspected of shooting dead Australian tourist Lucas Fowler, his US girlfriend and a university botanist.

We are constantly told things are getting worse for polar bears, especially those in Western Hudson Bay, because the ice-free season there was predicted to decline earlier than other regions. It hasn’t turned out that way but that does not stop the public rhetoric of doom or NGOs pleading for funds.
Last week, the Town of Churchill made public its first problem polar bear report of the year but oddly, it has only one entry. This is the first time I’ve seen such a sparse first report: since 2015, the first few incidents of the season have been subsumed into a first week report (issued no earlier than the first week of July) that announces the arrival of many bears on land.
Is this report of an isolated incident an attempt by Polar Bear Alert officials to make sure the first report of the season was not issued weeks later than usual? Or was it posted in isolation because the official response to the incident was caught on video and shared on social media (see below)?
UPDATE 22 July 2019: Published early this afternoon by the Town of Churchill, the problem polar bear report for the 2nd week of the season claims an error in last week’s report that they only just noticed when preparing this week’s report (but a full 24 hours after this blog post was published – but that’s probably a coincidence). Below is the report for week 2 (15-21 July 2019), showing that three incidents occurred last week.
