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 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.

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.

Straight from the horse’s mouth: all polar bear females tagged by researchers around Churchill in Western Hudson Bay last year were still on the ice as of 25 June. With plenty of ice still remaining over the bay, spring breakup will be no earlier this year than it has been since 1999. Contrary to predictions of ever-declining ice cover, the lack of a trend in sea ice breakup dates for Western Hudson Bay is now twenty years long (a hiatus, if you will) and yet these bears are repeatedly claimed to have been seriously harmed in recent years by a loss of sea ice.
In fact, WH bears have faced relatively few ‘early’ years of sea ice breakup and breakup has never come before the 15th of June. The earliest recent spring breakup date did not come in 2012 – when sea ice hit a summer record low – but in 1999, when Hudson Bay sea ice suddenly began to melt by late June rather than mid-July (Cherry et al. 2013; Castro de la Guardia et al. 2017; Lunn et al. 2016). And this year, as has been the case since 1999, breakup looks to be about two weeks later (give or take a week or so, at around 1 July), than was the case in the 1980s and early 1990s.
In other words, there has been no escalation of breakup dates since 1999: there has been no declining trend in breakup dates for Western Hudson Bay polar bears for 20 years (and no trend in fall freeze-up dates either).
UPDATE 26 June 2019: Here is the latest sea ice chart for the week of 24 June 2019 from the Canadian Ice Service (all that dark green is thick first year ice >1 m thick):

A thin polar bear has wandered more than 1000km south of the Kara Sea into the Siberian town of Norilsk, which has happened at least once before in the 1970s. It is reminiscent of a similar incident this past winter in Alaska and there is no reason to blame this on lack of sea ice.
From the Siberian Times earlier today (17 June 2019) comes the report that a bear that did not get enough to eat this spring (due to any number of reasons, including competition from larger, stronger bears) and went looking for easier food sources. No mention is made that this incident should be blamed on global warming.
Update 18 June 2019: Lack of any evidence that this incident was due to lack of sea ice didn’t stop Reuters from implying this was indeed the case, a theme picked up by the UK Telegraph, the BBC, and The Guardian.
