The polar bear became an ‘accidental icon’ of climate change. Is it time to rethink that?
Biologist Andrew Derocher wasn’t pondering of local weather change when he first began learning polar bears in Hudson Bay within the Eighties. A couple of decade into his profession, an image began to emerge: as sea ice diminished because of human-caused international warming, the polar bears he was learning had been venturing onto land earlier and returning to the ice later within the season.
It did not take lengthy for the world to note, and shortly the analysis was picked up by media, conservation teams and local weather deniers alike, he mentioned, turning the polar bear into an icon of a warming world, for higher or worse.
“Polar bears had been simply an early harbinger of change,” Derocher mentioned.
That standing was comprehensible; polar bears are the form of furry mammal we love to like — from a distance.
However as an icon within the struggle in opposition to local weather change, there are drawbacks, together with, as Derocher notes, situating the issue as “distant and distant” for Canadians dwelling outdoors the Arctic.
Inuit hunters have been vilified, and people who need to forged doubt on local weather science have focused the usually simplified messaging of polar bears in peril.
Now, with excessive climate exhibiting up throughout the nation — in additional frequent and extreme wildfires, drought and flooding — Derocher mentioned local weather change is turning into a extra instant subject for many individuals, generally fairly actually of their backyards, that does not want a distant mascot.

The polar bear’s rise to notoriety
For Derocher, how polar bears turned an “unintentional icon of local weather change” goes again a number of a long time.
It began with monitoring the animal to assist the polar bear hunt — taking a look at their numbers, well being and survival. In the meantime, different scientists had been accumulating knowledge about sea ice, however nobody had put the 2 issues collectively.
In 1993, Derocher and one other scientist, Ian Stirling, co-authored a paper, Possible Impacts of Climatic Warming on Polar Bears.
Disappearing ice in Hudson Bay in 1999 means polar bears cannot construct up their fats reserves and nourish their younger.
Within the Arctic, the oceans freeze on the floor, forming sea ice, which performs a job in conserving the local weather cool by reflecting daylight away. The ice can also be a part of the ecosystem, holding vitamins and contributing to your complete meals internet when it melts, from phytoplankton as much as the big animals like seals, which polar bears eat.
Some sea ice melts in the summertime and reforms within the winter, however knowledge was beginning to present the trend in sea ice was shifting and with it, the habitat polar bears depend on.
When Derocher and his colleagues reassessed the hyperlink between polar bears and local weather change in 2004, that paper “ignited the curiosity” of the media, Derocher mentioned.
Information shops weren’t alone. In 2006, former vp Al Gore featured an animated vignette of a polar bear drowning in his documentary An Inconvenient Fact. Conservation teams and local weather deniers had additionally taken notice.
“It turned kind of the villain for the individuals and people curiosity teams that did not need to see local weather motion, i.e., controls of greenhouse fuel emissions,” mentioned Derocher. “There’s kind of been some pluses and minuses to polar bears because the icon of local weather change.”
An image is simply a part of the story
In 2017, a conservation group launched a video of an emaciated polar bear that went viral. In a single model of the video, textual content says, “That is what local weather change seems to be like.”
The story that emerged was extra nuanced, and other people in Nunavut cautioned the footage confirmed a polar bear on the finish of its life fairly than the dramatic picture of worldwide warming that was prompt.
For Derrick Pottle, an Inuk hunter and information in Nunatsiavut, in northern Labrador, the polar bear, or nanuq in Inuktitut, conjures up a a lot totally different picture than an animal weak to local weather change.
It is “most likely essentially the most highly effective animal or mammal that we have now in our homelands,” he mentioned. “We perceive its energy, its intelligence … the need that it has to reside and it represents who we’re.”
For Pottle, the polar bear as a local weather icon has had “a damaging affect on the best way that we reside right here within the north.”
Now in his sixties, he has harvested ten polar bears in his life.
“You’re so joyful and so proud to convey again a meals and a meat supply and a possibility to make a number of {dollars} for your loved ones or you’ve got put clothes in your again,” he mentioned.
Polar bear harvesters used to earn as a lot as $20,000 for a conceal, mentioned Pottle, however now can be fortunate to get $5,000. He mentioned activists combating in opposition to polar bear searching make issues more and more troublesome.
In Nunatsiavut, a dozen polar bears may be legally hunted every year. In 1973, Arctic international locations from around the globe signed an settlement to preserve polar bears internationally, and in 2008 america listed the polar bear as a threatened species; Canada listed the animal as a species of particular concern in 2011.
For Pottle there are extra pressing indicators of local weather change than polar bears, just like the impacts on searching and trapping. Water that used to freeze by November within the Eighties now freezes in early January and melts in April fairly than Might or June, he mentioned.
“One time we may learn the ice and we had an understanding of the way it shaped,” he mentioned. “Half the time you do not know what you are going onto.”
Whereas melting sea ice is altering polar bears’ habitat and can proceed to take action, for now, some subpopulations of the animal have rebounded, and Pottle worries his expertise as a hunter and information just isn’t being taken significantly.
Subpopulations present a extra nuanced image
Biologist Andrew Derocher says the well being of the polar bear is “a posh subject.”
“We have got extra [polar] bears now than we did in 1973,” he mentioned.
“The problem is we have now additionally excellent data that at the least three populations of polar bears have declined because of the lack of sea ice and we suspect that that sample will simply improve.”
These complexities have been exploited by individuals arguing in opposition to the scientific consensus that international warming is actual and prompted principally by the combustion of fossil fuels.
“Local weather change deniers tried to come back at polar bears as a result of I feel in the event that they felt they might flip the tide of public opinion about that relationship between sea ice loss and polar bears, then the entire subject of local weather change would simply one way or the other unravel,” mentioned Derocher.
There are 19 subpopulations of polar bears dwelling around the globe within the Arctic with no “one-size-fits-all” image of how they’re responding to local weather change, mentioned Derocher.
“Each polar bear on the planet has skilled a change of their entry to sea ice within the final 30 years,” mentioned Jasmine Ware, a polar bear biologist with the federal government of Nunavut, which performs a job in managing greater than half of the worldwide inhabitants of polar bears.
Ware mentioned how these modifications to sea ice are affecting polar bears is determined by the place within the Arctic they reside.
Churchill, Man., close to the place Andrew Derocher does his analysis, is the southernmost a part of the polar bear’s vary.
As international warming continues to speed up, “we’re seeing increasingly bears going into dumps … from James Bay proper by way of to the excessive Arctic communities, and that is a recipe for issues,” mentioned Derocher.
Co-existence is essential
In July, a report co-authored by Derocher, cautioned that human meals is an “rising risk” to polar bears, emphasizing the necessity to safe issues like rubbish to assist preserve polar bears away and other people secure.
Over the a long time, Churchill, Man., has taken measures to enhance security by securing rubbish and making a warning system, setting an instance for different Arctic communities.
The city of Churchill, Man. offers with a harmful polar bear state of affairs when the ice of Hudson Bay fails to freeze by the top of November.
Annually when the ice melts, some polar bears make their technique to land and observe the western shore of Hudson Bay, by way of the neighborhood of Arviat, Nunavut, which sees the best variety of interactions between individuals and polar bears within the territory, mentioned Ware.
“There’s a change,” mentioned Ware. “A bear could possibly be encountered at any time. [There is] a really, very robust understanding that it is a harmful expertise and may be deadly.”
In 2018, Aaron Gibbons died defending his kids from a polar bear when he was out searching.
Since 2010, displays have patrolled Arviat to maintain polar bears away from the neighborhood.
When Leo Ikakhik will get a telephone name a few bear, he by no means is aware of what to anticipate when he exhibits up. “It is at all times a guessing recreation,” he mentioned. “I’m wondering if the bear’s going to run or is the bear going to only stand his floor?”
Ikakhik makes use of bear bangers, which make a loud noise to discourage the bear, and mentioned he has been fortunate to by no means have resorted to utilizing the rifle he carries as a backup.
Transferring past the polar bear as local weather icon
Kari Marie Norgaard, a professor of sociology and environmental research at College of Oregon, can see why polar bears did catch on as an emblem of Arctic change.
“It is one thing that kids have an attachment to or it is this iconic animal in sure methods. However I feel we’d like heaps and plenty of symbols, not only one,” she mentioned.
“Any form of image that factors to collective motion… can be extra helpful.”
Moderately than an icon, it is likely to be speaking about how local weather change is affecting somebody personally that motivates motion, mentioned Norgaard.
Norgaard works with the Karuk Tribe in California restoring Indigenous fire practices, which will help handle wildfires and the dangers close by communities face.
“We aren’t helpless, however we have now to know what we will do.”
