Polar bears that have come off the sea ice of Hudson Bay near Churchill, Manitoba in Western Hudson Bay are apparently in a wide variety of conditions, from very fat to skinny. So, not all skinny despite the relatively early breakup of ice in the northwest.
Most of the ice was gone from the NW of Hudson Bay for the week of 23 July 2018 and the graph below shows that this is a new pattern that began in 1997, with only 2009 being an outlier:

Less than a month after a fatal polar bear attack near Arviat, Western Hudson Bay, European media reported this morning that one of two German polar bear guards escorting a group of tourists on a shore visit in northern Svalbard was mauled on 28 July by a polar bear before the second guard could kill it.
The man was air-lifted to hospital in Longyearbyen with non-life-threatening head injuries. Whether the bear was fat or thin was not mentioned but a necropsy will be performed.
More details are likely to be available within the next few days. The guards and tourists were from the German cruise ship MS Bremen, which apparently is operating a live web cam. The group landed on the Sjuøyane Islands, the northernmost group of islands in the Svalbard archipelago (see the top of the black box on the map below).
UPDATE 28 July 2018 11:00 pm PT: The photo of the dead bear (above, provided by the Governor of Svalbard), shows the animal was in poor condition. See my comments below regarding sea ice coverage for the area: the bear had likely been on the islands since early May and if he was not in good condition when he left the ice, he would have been desperate by now. However, we still do not know if he was sick or injured, young or old. That information will come with time.
UPDATE 29 July 2018: The cruise ship line has released a statement on Facebook that includes further details about the attack, see below.
Remember that video of an emaciated
Baffin Island Somerset Island polar bear that went viral last December?1 In an unexpected follow-up (“Starving-Polar-Bear Photographer Recalls What Went Wrong“; National Geographic, August 2018 issue), photographer Cristina Mittermeier makes some astonishing admissions that might just make you sick.
It turns out they didn’t just come across the dying bear the day it was filmed: it was spotted at least two days earlier by Paul Nicklen. He must have had a satellite phone with him when he saw the bear but the only call he made was to his film crew — he made no attempt to find a local conservation officer to euthanize the bear, which would have been the right thing to do.
ADDED July 27 2018: Calling a conservation officer to euthanize the bear would have been the right thing to do not only out of compassion (and to know the cause of illness, because a necropsy would have been done), but because a starving bear is especially dangerous: it would have been a potential danger to any unsuspecting person who set foot on the island (he was strong enough to swim away, so was probably strong enough to kill a child, if not an adult).
The bear’s emaciated, near-death stagger2 was simply too tantalizing to pass up (video needs action: an emaciated dead bear would not been nearly as effective). Mittermeier claims they knew when they filmed the bear that he was sick or injured, but Nicklon presented it as an effect of climate change regardless. Mittermeier now says National Geographic simply “went too far” with their video caption (“This is what climate change looks like“), that she and Nicklan “lost control of the narrative.”
Actually, what they lost was their humanity.

At the end of June, there were nine bears remaining from the original 14 that were tagged with glue-on ear transmittors in April 2018 near Kaktovik, Alaska by US Geological Survey biologists.
Below is the June 2018 tracking map (high resolution image is here):
Original caption: “Movements of 9 satellite-tagged polar bears for the month of June, 2018. These bears received satellite eartag transmitters in 2018 on the spring-time sea ice of the southern Beaufort Sea. Polar bear satellite telemetry data are shown with AMSR2 remotely-sensed ice coverage for 30 June, 2018.”
See the close-up for June 2018 below:
As ear tags are notoriously short-lived, there may not be any remaining by the end of July but if there are, I will post the tracks. The map for May 2018 is below.
Second week of Polar Bear Alert Activity reports (16-22 July) for 2018 and already two bears are in jail, making it the busiest 3rd week in July since 2015:
Headline run by The Independent last Friday (20 July 2018):
‘A death sentence for polar bears’: Trump administration seeks changes to endangered species protections: Conservation groups are already vowing to sue the Donald Trump administration if the revisions go into effect
Such over-the-top rhetoric is as predictable as puddles after a cloud-burst (see a statement by the WWF here, and the Center for Biological Diversity (source of the “death sentence for polar bears” claim here) but the proposed changes only apply to future listings, not listings already in place. See the USFWS press release below.
However, both The Independent and ABC News featured polar bears in their stories, a species listed as threatened in 2008.
It would be hard to beat the irony of ABC: it ran video of fat Kaktovik polar bears behind their anchor as he delivered the ESA story. The Independent not only used the “death sentence to polar bears” quote but included the video clip from last year of the dying Baffin Island bear even though it is very likey the bear was emaciated due to cancer rather than lack of food (Crockford 2018).
Why would anyone mention polar bears? Why is the Center for Biological Diversity so afraid?
Because if polar bears face a delisting challenge, the new rules apply.

Additional information is available regarding the fatal mauling of a young Arviat father two weeks ago that may answer the question of why the bear left the Hudson Bay sea ice well before it was necessary. Was it lack of sea ice (blamed on global warming), as biologist Ian Stirling recently insisted — or did natural food attractants lure the bear ashore prematurely?
I would also like to appeal to readers to consider a donation to the Go Fund Me campaign set up to support the widow and children of Aaron Gibbons, who was only 31 years old. So far, there has not been an overwhelming response (less than 1/2 of the modest goal of $5,000 met after two weeks) and that saddens me deeply.
I have contributed myself but each individual can only do so much. Imagine losing your spouse in this most vicious manner (the children witnessed the attack and were the ones that called for help) and think of the challenges of healing your family and keeping it afloat financially. Please see the GO FUND ME page and contribute if you can.
What I’ve learned over the last week is that the polar bear that killed Aaron Gibbons was a big male in poor condition but he was not the only bear onshore at the time. In addition, the Arctic tern nesting colony on Sentry Island was undoubtedly an enticing natural attractant that seems to have encouraged these bears to leave the ice far north of where they might otherwise have come ashore.
UPDATE 20 July 2018: I’ve added the most recent (19 July) map of collared WH polar bear locations on Hudson Bay to the “Condition of the Sea Ice” discussion below. Also, I am pleased to see that the GO FUND ME campaign has now gone above the half-way mark (~$2800.00 as of 2:00 PM Pacific time). My personal thanks to every one who was able to contribute. I hope to see the goal reached within the next few days.
UPDATE 6 September 2018: A news announcement today revealed that the necropsy done on the bear that attacked Aaron Gibbons was an adult male in “fair” condition (thin but not skinny). See my report here and the news story here. And I’m pleased to report that the GoFundMe goal of $5000 for Aaron’s family has been reached: thanks to all PolarBearScience readers for their support.

Sea ice is said to be “an essential habitat for polar bears” but that’s an overly simplistic advocacy meme as ridiculous as the “no sea ice, no polar bears” message with which the public is constantly bombarded. Polar bears require sea ice from late fall to late spring only: from early summer to mid-fall, sea ice is optional. Historical evidence of polar bears that spent 5 months on land during the summer of 1874 proves an extended stay ashore is a natural response of polar bears to natural summer ice retreat, not a consequence of recent human-caused global warming. Sea ice is a seasonal requirement for polar bears: it’s not necessary year round.
[This PBI newsletter from 2011 repeats this meme and Andrew Derocher’s recent tweet conveys a similar message (“Sea ice loss = habitat loss for polar bears”)]
As long as sea ice is available from late fall through late spring (December to early June) and accompanied by abundant seal prey (sometimes it isn’t, see Derocher and Stirling 1995; Stirling 2002; Stirling et al. 1981, 1982, 1984), polar bears can survive a complete or nearly complete fast from June to late November (and pregnant females from June to early April the following year). That’s the beauty of their Arctic adaptation: fat deposited in early spring allows polar bears to survive an extraordinary fast whether they spend the time on land or sea ice.
Young and very old bears, as well as sick and injured ones, are the exception: these bears often come ashore in poor condition and end up dying of starvation — as a much-publicized bear on Baffin Island who likely had a form of cancer did last summer (Crockford 2018). Competition with bigger, stronger bears means these bears can’t keep what they are able to kill and they are most often the bears who cause problems. Starvation is the leading natural cause of death for polar bears because if they cannot put on the fat they need in spring, they will not survive the low food months of summer and winter, whether they are on land or out on the sea ice (Amstrup 2003).

According to the Guardian (9 July 2018), there is a “global heat wave” going on right now.
In Siberia, the heat is supposedly “completely unprecedented” and will surely (we are told) impact Arctic sea ice — the habitat of the iconic polar bear. Yet a comparison of previous years shows little to no impact on sea ice: there is more ice present than there was in 2007.
Said The Guardian:
“But though we cannot say definitively that the current heatwave is caused by carbon emissions, it fits the pattern of long-term changes that we call climate. It is part of a global phenomenon, even if not the most important part. The really significant change is happening in eastern Siberia at the moment, where a completely unprecedented heatwave is warming that Arctic coastline, with consequences that are unpredictable in detail but surely bad on a large scale.” [my bold]
The heat — which some folks admit they not only expect during this season called summer but anticipate with joy — has been around since late June, with several locales outside Siberia affected, including southern Ontario, Quebec, Los Angeles CA, Britan, many locations in the eastern USA, Europe.
With so many locations across the Northern Hemisphere experiencing very hot weather over the last few weeks (maybe record-breaking, maybe not), let’s take a look at what all that heat is doing to Arctic sea ice compared to previous years.
A brave young father from Arviat on the northwest coast of Hudson Bay was killed yesterday evening by a polar bear while trying to protect his children.
Aaron Gibbons, 31, was the nephew of Gordy Kidlapik, who follows this blog and my twitter account. Gordy has often sent me useful local information and perspectives from Arviat, which is in Nunavut (north of Churchill, Manitoba).
It was heartbreaking to hear this news firsthand from Gordy:
More below and to follow as further details emerge. My sincere condolences to Gordy and his family – what a horrific loss.
UPDATE: 4 July 2018 9:00 pm PT. See correction below regarding the last fatal WHB attack, which was in 1999 (Rankin Inlet), not 1983 as my original title read. My apologies but as you’ll see, the newspaper didn’t get it right either.
