A polar bear was spotted this year on Bear Island (Bjørnøya) in the southern Barents Sea on 8 March by the crew at the Meteorological Station. The last time these workers had seen a polar bear was 2011 but this year extensive Barents Sea ice literally brought a bear to their doorstep, similar to the way that sea ice brings bears to southern Labrador and Newfoundland in late winter and spring.
After below-average ice cover around Svalbard for most of the winter months of January and February, by early March the ice had expanded so far to the south it reached Bjørnøya. It was the kind of ice that hadn’t been seen in decades and almost immediately, a polar bear was spotted on shore. Given the length of time that the ice surrounding the island persisted, it is likely more bears came ashore but were not seen: the Meteorological Station at the north end of the island is the only place that people live over the winter (see maps below).

In late June, one of the most powerful icebreakers in the world encountered such extraordinarily thick ice on-route to the North Pole (with a polar bear specialist and deep-pocketed, Attenborough-class tourists onboard) that it took a day and a half longer than expected to get there. A few weeks later, in mid-July, a Norwegian icebreaker also bound for the North Pole (with scientific researchers on board) was forced to turn back north of Svalbard when it unexpectedly encountered impenetrable pack ice.

Apparently, the ice charts the Norwegian captain consulted showed ‘first year ice‘ – ice that formed the previous fall, defined as less than 2 m thick (6.6 ft) – which is often much broken up by early summer. However, what he and his Russian colleague came up against was consolidated first year pack ice up to 3 m thick (about 10 ft). Such thick first year ice was not just unexpected but by definition, should have been impossible.
Ice charts for the last few years that estimate actual ice thickness (rather than age) show ice >2 m thick east and/or just north of Svalbard and around the North Poie is not unusual at this time of year. This suggests that the propensity of navigational charts to use ice ‘age’ (e.g. first year vs. multi-year) to describe ice conditions could explain the Norwegian captain getting caught off-guard by exceptionally thick first year ice. It also provides an explanation for why the polar bear specialist onboard the Russian icebreaker later failed to explain that first year ice of such shocking thickness was truly extraordinary, not just a bit thicker than usual.

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.

Summer sea ice loss is finally ramping up: first year is disappearing, as it has done every year since ice came to the Arctic millions of years ago. But critical misconceptions, fallacies, and disinformation abound regarding Arctic sea ice and polar bear survival. Ahead of Arctic Sea Ice Day (15 July), here are 10 fallacies that teachers and parents especially need to know about.

This essay explains in simple terms why so many people still believe that polar bears are in peril when nothing could be further from the truth: it is an essential lesson that shatters the basis of the shameful indoctrination of young school children and undermines the baseless claims of activist protestors. It was written and translated into French for a special climate change feature issue (July) of the monthly French magazine Valeurs Actuelles (reviewed here) and reprinted by the French hunting magazine Chasses Internationales. It has also been translated into German for a dedicated climate change issue (11 July) of the Swiss weekly magazine Die Weltwoche.
I have added a couple of figures to illustrate this English version of the essay.

One of the first of hundreds of polar bears expected to come off the sea ice of Hudson Bay along the west and south coasts was captured on video on 5 July. This is only the first wave, as there is still so much ice remaining that most of the bears are likely to remain offshore: not because there is so much food available (few seals are caught at this time of year) but because the ice is where they are most comfortable.
