Historic hot spells in Churchill, Polar Bear Capital of the World, in late June/early July

Posted on June 29, 2019 | Comments Off on Historic hot spells in Churchill, Polar Bear Capital of the World, in late June/early July

Amid reports of a late June heat wave in Europe this year, I thought I would check out the temperature in Churchill, Manitoba – where sea ice off the coast has been rather slow to melt this year with no reports yet of polar bears onshore. It turns out that Churchill has fairly often seen very hot weather (around 900F/300C) for a few days at this time of year but 2019 has certainly not been one of them. Temperatures in Churchill on 28 June this year were about 40 degress F below previous highs (more than 15 degrees C) according to online Environment Canada weather comparison reports that go back to 1943 (although their records for Churchill go back to 1929).

High for 28 June 2019: 44.4 F/7.1 C

Hottest year, late June: 90.0 F/32.2 C on 29 June 1984 [also 87.8 F/30.6 C on 26 June 1967]

Hottest year, early July:  93.0 F/33.9 C on 4 July, 1975 [also 91.0 F/32.8 C on 3 July 1976]

Bottom line: It is appropriate to scoff at anyone who claims it never got hot in the Arctic before sea ice declined markedly around the turn of the 21st century. For Churchill (self-proclaimed Polar Bear Capital of the World), there are plenty of records of brief spells of hot weather in late spring/early summer (as well as in other months) that go back to the decades when sea ice conditions were supposedly ideal for polar bears.

Now 20 years with no trend in ice breakup dates for Western Hudson Bay polar bears

Posted on June 26, 2019 | Comments Off on Now 20 years with no trend in ice breakup dates for Western Hudson Bay polar bears

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):

Skinny polar bear far inland in Siberia not due to sea ice loss but a rare normal event

Posted on June 17, 2019 | Comments Off on Skinny polar bear far inland in Siberia not due to sea ice loss but a rare normal event

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.

Polar bear habitat update at mid-June: more than enough for survival

Posted on June 16, 2019 | Comments Off on Polar bear habitat update at mid-June: more than enough for survival

Here we are at the middle of June, when most polar bears are pretty much done with hunting seals for the season. And despite hand-wringing from some quarters, sea ice extent is down only marginally from average at this time of year and certainly not enough to impact polar bear survival.

Given the large expanse of open water in the Southern Beaufort so early in the season, one resident pessimist insists those polar bears are “challenged” by the lack of ice. If he is right, there should be reports of dozens upon dozens of skinny and dying bears along the coast of Alaska this summer. If not, he will pretend he never suggested any such thing.

So far, despite the early loss of ice in some regions, there have been no reports of polar bears ashore unusually early. Hudson Bay still has lots of thick first year ice, so despite the overall reduced Arctic ice coverage, none of the three Hudson Bay polar bear populations are facing the earlier-than-usual sea ice breakup this year as we keep being promised will show up. In fact, there hasn’t been a significantly early breakup in Western Hudson Bay since 2010 (see previous posts here and here).

Today: Talking with Glenn Beck later this morning about the Netflix walrus fiasco

Posted on June 5, 2019 | Comments Off on Today: Talking with Glenn Beck later this morning about the Netflix walrus fiasco

At 11:30 am ET, I will be talking to Glenn Beck on his radio program about the lies and misinformation that Netflix and WWF are spreading via their ‘Our Planet’ documentary sequence on Pacific walrus, aided and abetted by narrator Sir David Attenborough.

I will post a link to the podcast as soon as I am able.

Activists who use polar bears as a symbol of climate change are out of touch with reality

Posted on June 3, 2019 | Comments Off on Activists who use polar bears as a symbol of climate change are out of touch with reality

Young activists like Ollie Nancarrow from the UK need to find another symbol for their messages of climate change. Polar bears are thriving despite recent dramatic declines in summer sea ice: they have not been devastated as predicted by declining summer sea ice blamed on climate change. Anyone who uses a polar bear image to further a message of climate change, as Ollie has done, is simply out of touch with reality.
