Starvation due to natural causes is the leading cause of death for polar bears and loss of body condition (getting thinner) is therefore the first symptom of impending death for virtually all polar bears that die naturally. However, polar bear specialist Andrew Derocher claims that loss of body condition is also the first symptom of climate change for polar bears.
But how do you tell the difference between polar bears made thin by man-made climate change and those who are thin due to natural causes?
You can’t. Even a necropsy will not be conclusive because there are so many natural reasons for a bear to lose weight — and even starve to death — that’s it’s virtually impossible to say that any thin bear is skinny due to a lack of sea ice.
Emaciated polar bears like the one above from Somerset Island in the Canadian Arctic,1 captured on camera in August 2017, are being used to promote the idea that polar bears are already dying of starvation due to climate change. That’s a big white lie, as the headline above suggests: seven months later, National Geographic has admitted as much. Here I show why it could not have been true in the first place (with references from the scientific literature).
UPDATE: 29 August 2018: See my op-ed in the National Post (29 August 2018) and the GWPF video below on this issue:

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.
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.

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.
