The activist lawyer primarily responsible for polar bears being listed as ‘threatened’ on the US Endangered Species List (ESA) in 2008 is frustrated that those efforts have not generated her preferred political action. Kassie Siegel also claims in another 10 years it will be too late to save polar bears from extinction — despite clear evidence to the contrary.
In an emotional rant over at The Hill with a predictably hysterical headline, Siegel perhaps reveals more than she should about her motivation (“Keeping fossil fuels in the ground is the only way to save polar bears ravaged by climate change,” 26 May 2018).

Optimism in conservation science — which the Smithsonian says we desperately need (Earth Optimism Summit 21-23 April 2017, apparently a huge success) — means it’s time to acknowledge and celebrate real conservation success stories. The Smithsonian folks probably won’t say it but I will — one of those successes is the recovery of polar bears.
It’s time to abandon the focus on prophesies of impending loss and accept that recovery of polar bears from the over-hunting of last century has continued despite a decade of low summer sea ice (Aars et al. 2017; Crockford 2017; Dyck et al. 2017; SWG 2016; York et al. 2016). Why not focus on the numerous images of fat, healthy bears rather than the anomalous starving ones?
It’s time to let go of imagined future catastrophes based on pessimistic failures of adaptation (Amstrup et al. 2007, 2008; Atwood et al. 2016; Stirling and Derocher 2012) and acknowledge that polar bears and Arctic seals, just like Pacific walrus (MacCracken et al. 2017; US Fish & Wildlife Service 2017), are resilient species with adaptive capabilities we are only just beginning to comprehend (Crawford and Quakenbush 2013; Crawford et al. 2015; Escajeda et al. 2018; Rode et al. 2014; Stirling and Lunn 1997; Stirling et al. 1975a; Vibe 1965).

In early October, the US Fish & Wildlife Service reversed its 2011 decision to list Pacific walrus as ‘threatened with extinction’, saying they could not “determine with certainty that walruses are likely to become endangered “in the foreseeable future.” [details below]
I have argued that the 2008 decision by the USFWS to list polar bears as ‘threatened’ is similarly lacking in certainty (Crockford 2017) and as for walrus, the previous determination of ‘threatened’ for polar bears was premature and should be reversed.
A prominent biology colleague and I recently put it this way in a newly published essay:
“Is it ethical or fair to the many citizens impacted directly and indirectly by the 2008 polar bear ruling for the FWS to allow polar bears to remain on the Endangered Species List?”
Read our piece in the winter 2018 issue of RANGE Magazine (open access), authored by myself and Dr. Valerius Geist, professor emeritus of environmental science at the University of Calgary, Alberta.

PS. You’ll find an excellent piece on wildfires by biologist Jim Steele in the same issue.
See also Crockford, S.J. 2017. Testing the hypothesis that routine sea ice coverage of 3-5 mkm2 results in a greater than 30% decline in population size of polar bears (Ursus maritimus).

Details on the USFWS decision on the walrus is below. Note that like the walrus, if ESA protection on the polar bear was reversed, the bears would still be strongly protected under the Marine Mammal Protection Act (as they have been since 1972), and like the walrus, polar bears have shown an ability to adapt that was not foreseen in 2007 (as evidenced by their failure to die off droves in response to recent sea ice declines).

“Lies” might be a better word to characterize the misinformation that scientists and the media have been busy spreading to the public over the last few weeks. The information is either known to be false (by scientists whose job it is to relay facts honestly) or is easily shown to be false (by journalists whose job it is to fact-check their stories).

“U.S. Fish and Wildlife Service officials said they cannot determine with certainty that walruses are likely to become endangered “in the foreseeable future,” which the agency defines as the year 2060.”
(CBC, 4 October 2017).
“The agency said in 2011 that walruses deserve the additional protection of being declared threatened, but delayed a listing because other species were a higher priority.
The agency revised the decision based on new information, said Patrick Lemons, the agency’s marine mammals management chief.
“Walrus demonstrated much more ability to change their behaviours than previously thought,” Lemons said. Their ability to rest on shorelines before swimming to foraging areas makes the threat of less sea ice uncertain, he added.”
This year’s baseless media frenzy over walrus survival and loss of summer sea ice blamed on human-caused global warming was initiated by a press release from US Fish and Wildlife last week (16 August 2017, pdf here: “Pacific walruses haul out near Point Lay earlier than in previous years“). Quote below, my bold:
In the first week of August, several hundred Pacific walruses were observed on a barrier island near the Native Village of Point Lay, a small, Iñupiaq community on the northwest coast of Alaska. This is the earliest date yet for the haulout to form…This year, sea ice has retreated beyond the continental shelf earlier than in previous years
But is this all true? In a word, no — and it didn’t take much research to uncover the truth.
UPDATE 24 August 2017: A few minutes after this post was published, I became aware that just yesterday, 20 conservation activist organizations, lead by the Center for Biological Diversity (who led the polar bear listing charge) issued a press release regarding a letter (pdf here) pressuring the US Fish and Wildlife Service to list Pacific walrus as threatened or endangered under the Endangered Species Act. Apparently, a decision must be made by the end of September on whether to actively list walrus or not. The text below has been amended to reflect this development.

I knew it was coming up and then forgot to check, but sometime about 2 weeks ago blog views here at PolarBearScience passed the one million mark — more than two months ahead of my 5th anniversary.
Over 1 million views, four polar bear books (including my first novel, the polar bear attack thriller EATEN), several white-paper type publications (here, here, and here), several magazine articles (one here), two videos (see below), and a scientific paper on polar bear conservation that was peer reviewed before it’s publication at PeerJ Preprints.
Not bad for a five year stint on a blog with a single species focus. Continue reading
