Fact: polar bears are thriving despite sea ice loss according to the scientific literature

Is Facebook now an expert on polar bear conservation status? Apparently they have decreed themselves the last word for online content. There is a plan afoot to label anything that says polar bears are not being harmed by recent sea ice declines as ‘disinformation’ – but on whose authority? Thanks to Josh for the cartoon below.

A new section of the Climate Science Information Center, launching alongside the labelling trial, debunks common myths such as the false claim that polar bear populations are not suffering due to global heating, or the widespread belief that excess carbon emissions help plant life. Facebook is working with climate communication experts from around the world, including at the University of Cambridge, to produce the content.

Ah, they’re consulting ‘climate communication experts‘! Those experts surely must be up on all the latest papers and not trusting the word of obviously biased conservations organizations like the WWF or PBI whose real reason for existence is the generation of as much money in donations as possible?

The peer reviewed literature supports the claim that polar bears are currently thriving despite recent ice declines – especially in the Chukchi and Barents Seas – regardless of what computer model predictions say about what might happen in the future. This is a fact, not a ‘myth’. See my paper from 2017 and my 2019 book for most of the citations (Crockford 2017, 2019) and others in the reference list below. Check them out yourself before you believe Facebook. Ask me for any paper you’d like to see via the ‘contact me’ form and I’ll send it along. Also, look for my State of the Polar Bear Report 2020 next week.

Blacklist by Nature follows defamation by BioScience: journals reject ethics of science

Along with hundreds of other people – 385 to be exact – I have been blacklisted [#181] by the science journal Nature Communications in a recently-published abysmal paper by three authors from University of California Merced, after I and a number of others were publicly defamed by a squadron of authors in a similarly-stupid paper less than two years ago in the general interest journal BioScience. This obsession that scientists-with-a-message have about silencing peers with other viewpoints (rather than constructing and communicating a winning argument themselves) is vile and utterly counter to what real science is about. Not surprisingly, they positively fawn over media stars like Al Gore and Greta Thunberg who have no science background but willingly repeat the accepted message of climate-change-doom.

Stupidest paper ever final

Now we have two stupid papers that purport to uphold the sanctity of one particular view of climate change: the Harvey et al. “absolutely the stupidest paper I have ever seen published” (Curry 2017) – which we all truly thought could not be matched – and now the Petersen et al. “worst paper published in a reputable journal” (Curry, 2019).

Judith Curry: “Apart from the rank stupidity of this article and the irresponsibility of Nature in publishing this, this paper does substantial harm to climate science.

Jo Nova: “Skeptics get banned, rejected, blocked and sacked from the mainstream media yet somehow Nature has a paper on Skeptics getting too much media. Believers don’t have to be an expert to control the news agenda, just a Greenpeace activist, or a teenage girl. Skeptics on the other hand, can be Nobel Prize winners, but the BBC won’t even phone them.”

UPDATE 18 Aug. 2019: Additional commentary on this new paper (new or previously overlooked in my initial story); do cruise the comments, some additional gems of analysis there:

ADDED 20 Aug 2019: See this scathing letter to the Editor of Nature Communications by President of the National Association of Scholars, Peter Wood. (15 Aug 2019). In part, he states:

“Nature Communications has published an article which forwards the technology of censorship in pursuit of political activism, but which does not even pretend to forward scientific knowledge.”

Polar bear specialist Mitch Taylor on accountability in polar bear science

Polar bear specialist Mitch Taylor emailed me and others his response to the New York Times article that appeared Tuesday (10 April) about the Harvey et al. (2018) BioScience paper attacking my scientific integrity. Here it is in full, with his permission, and my comments. Don’t miss the footnote!

New paper asks: Has recent sea ice loss caused polar bear populations to crash?

A paper published today finds that predictions of polar bear population crashes due to summer sea ice loss are based on a scientifically unfounded assumption.


[The graphic above was created by me from the title page and two figures from the paper]

Specifically, this paper of mine addresses the basic premise upon which predicted population declines linked to modeled habitat loss made by polar bear specialists back in 2006 and 2008 (by the International Union for the Conservation of Nature, IUCN, and the US Fish and Wildlife Service, USFWS), and concludes that when assessed as a testable hypothesis against data collected since then, it must be rejected.

The forum for this paper is PeerJ Preprints,  which I found while looking for recent research papers about ringed seals. I discovered that Canadian ringed seal biologist Steven Ferguson recently used this service, which is free, open access, accepts review commentary, and will show up on Google and Google Scholar searches.

I decided that if this publication forum was good enough for Ferguson and his Arctic research community, it was good enough for me.
