Scientists and media continue to spread misinformation about polar bears & walrus

“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).

Breaking: Pacific walrus is not threatened with extinction says US Fish & Wildlife

“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.”

Pacific walrus haulout two weeks early, US gov’t agency blames “earliest” ice loss

Walrus 2012 July USGSThis 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.

Just when I wasn’t paying attention: 1 million views surpassed

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.

Stats at 26 May 2017 total_PolarBearScience

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

Will Trump reverse ESA decisions listing polar bears & Arctic seals as threatened?

The New York Times reported this morning: “Donald Trump Is Elected President in Stunning Repudiation of the Establishment.”

I’ve never been very interested in politics but this result has me wondering. Could the new president reverse the Endangered Species Act (ESA) decisions listing polar bears and other species as ‘threatened’ with extinction due to future threats from global warming?

New ecology book: 25 MYTHS THAT ARE DESTROYING THE ENVIRONMENT

Veteran Yale University research ecologist Dan Botkin has a new book coming out tomorrow (Saturday 15 October) that you might want to look at:

botkin-2017-25-myths-cover

A number of chapters are relevant to polar bears, including these three:

“Myth 11: Without Human Interference, Earth’s Climate is Stable”

“Myth 13: Climate Change Will Lead to Huge Numbers of Extinctions”

“Myth 25: Compared to Climate Change, All Other Environmental Issues Are Minor”

I found the book clearly written in a readable style (Table of Contents here). It provides timely insight into critical issues related to conservation and species extinction, with many real-world examples that counter theoretical assumptions (polar bears are discussed in the Overview). I found the energy issues (Myths 23 and 24) an awkward distraction but others might find them of interest. It’s a good companion to Bjorn Lomborg’s The Skeptical Environmentalist (an excellent reference from 2001 but much more detailed).

Pre-0rders now being taken:

Twenty-five Myths That Are Destroying the Environment: What Many Environmentalists Believe and Why They Are Wrong. Daniel B. Botkin 2017. Rowman & Littlefield Publishers, Inc., Lanham, MD 20706. $12.71 PAPERBACK; $7.51 KINDLE

USGS report on history of walrus haulouts leaves out correlation with population size

Walrus researchers from the US Geological Survey have a new report on the history of walrus haulouts in the Chukchi and Bering Seas – yet their media efforts (via press release and interviews) fail to mention the relationship between fluctuating size of walrus haulouts and fluctuating walrus population size that is evident in that history. In fact, overall population size is not mentioned at all.

Walrus 2012 July USGS

Two articles came out over the weekend that announced the results of this new joint US-Russian initiative [PBS, Walrus beaching in Alaska might not be as harmful as it looks. Here’s why – 31 July 2016 and ADN, Alaska and Russia join forces to create 160-year database of walrus haulouts – 31 July 2016]

But neither articles nor the new USGS paper they are touting (Fischback et al. 2016) mention the huge summer/fall haulouts of females, calves, and juveniles that were documented in the 1970s that coincided with the huge population size at that time, which crashed in the 1980s.

Only now has the population grown (to at least 200,000) to the point that huge haulouts are again being reported – conservation has done it’s job. But when walrus numbers get too high the animals out-strip their food source and numbers plummet, as they did in the 1980s (Fay et al. 1989; Garlich-Miller et al. 2011). See my fully referenced summary paper, Crockford 2014 (On The Beach: Walrus Haulouts are Nothing New).

Here’s the concern: When (not if) a population crash happens again, will it be blamed on global warming rather than natural causes? According to the PBS article:

“The database is supposed to help federal officials with conservation, especially as more ships start sailing through the newly open waters. The U.S. Fish and Wildlife Service is determining whether walrus should be listed as a threatened species.[my bold]
