Amstrup & colleages can’t refute my critique of their 2007 polar bear survival model, Part 1

It’s been more than a year since I first published my scientific manuscript at PeerJ Preprints (a legitimate scientific forum) on the failure of Amstrup’s 2007 USGS polar bear survival model (Crockford 2017), a year waiting in vain for the polar bear community to comment. They either couldn’t be bothered or knew they couldn’t refute it – I haven’t known for sure which. But I do now.

Polar bear specialists didn’t comment because they couldn’t refute it in the scholarly manner required by PeerJ: all they could do is tear it down with derision, misdirection and strawman arguments.

I know this because the damage control team for the polar-bears-are-all-going-to-die-unless-we-stop-using-fossil-fuels message wasn’t activated over my fully-referenced State of the Polar Bear Report for 2017 (Crockford 2018) released on International Polar Bear Day last month, but for a widely-read opinion piece I’d written for the Financial Post published the same day (based on the Report) that generated three follow-up radio interviews.

By choosing to respond to my op-ed rather than the Report or my 2017 paper, biologists Andrew Derocher and Steven Amstrup, on behalf of their polar bear specialist colleagues1, display a perverse desire to control the public narrative rather than ensure sound science prevails. Their scientifically weak “analysis” of my op-ed (2 March 2018), published by Climate Feedback (self-proclaimed “fact checkers”), attempts damage control for their message and makes attacks on my integrity. However, a scientific refutation of the premise of my 2017 paper, or The State of the Polar Bear Report 2017, it is not (Crockford 2017, 2018).

Derocher further embarrasses himself by repeating the ridiculous claim that global polar bear population estimates were never meant for scientific use, then reiterates the message with added emphasis on twitter:

Just as the badly written Harvey et al. (2017) Bioscience paper said more about the naked desperation of the authors than it did about me or my fellow bloggers, this attempt by the polar bear community’s loudest bulldogs to discredit me and my work reveals their frustration at being unable to refute my scientifically supported conclusion that Amstrup’s 2007 polar bear survival model has failed miserably (Crockford 2017).

BioScience pushback update and plea for a virtual beer

Writing this blog takes a lot of time and effort but it gives me immense personal and professional satisfaction. I get emails from readers all over the world saying how much they appreciate what I do for science. The fact that my colleagues felt threatened enough to publish a malicious hit piece attacking my scientific credibility tells me I’m reaching a wide and influential audience that are convinced by the science I present.Crockford and Polar bear_0245 sm

My books are getting good reviews. I discount the few Harvey et al. supporters that showed up in the days after the BioScience paper appeared in late November to write some Harveyesque comments in the Amazon review section for my Polar Bear Facts & Myths kids’ science book. A thuggish stunt but predictable given the nasty tone of the paper.

I’m not worried, though: book sales over the last couple of months have been very good, even though my university didn’t issue a press release to promote my kids book like Penn State did today for Harvey et al. co-author Michael Mann. I know that folks will head to Polar Bear Facts & Myths for a child-appropriate science book about polar bears, and to Mann’s Tantrum book if they want their kids to be petulant activists before they finish elementary school.

You might be interested to know I’ve decided not to take legal action against the Harvey cabal responsible for the defamatory BioScience paper.  I’m not backing down. I will definitely be pushing back (already started) but doing so will take time away from my paid work.

Blog uses my polar bear info but no link to PBS means they are ‘science-based’

According to Harvey and colleagues (2017), any internet posting that discusses polar bears without a link to PolarBearScience or a mention of my name can be considered a ‘science-based’ blog. But they missed an obvious catch: bloggers who use my content without attribution.

For example, so-called ‘science-based’ blog Churchill Polar Bears, written by Churchill polar bear guide Steve Seldon, used text and two of the four figures provided in a 15 February 2017 post at PolarBearScience to create a Churchill Polar Bears post on 17 February but did not include a single link to PolarBearScience indicating that’s where he got his information (Wayback machine link here).

A few would not consider this plagiarism but most do. That is to say, failure to attribute a source when work or information is not your own is a big no-no in science, as it is in all of academia.

Consider this evidence: Continue reading

Bioscience editor tells journalist he won’t retract Harvey paper

I shouldn’t be surprised that a journal editor who would publish — and then staunchly defend — a paper that deliberately trashes the reputation of a respected scientist would tell the media before anyone else of his decision regarding a retraction request.
