Did Harvey et al. authors aim to help Google censor polar bear information?

A recent New Time Times article about Google’s practice of generating ad revenue via ‘promoted’ search results (“How Climate Change Deniers Rise to the Top in Google Searches” 29 December 2017) had a surprising and disquieting ending about the prospect of internet censorship.

It was a quote from Jeff Harvey of “Internet Blogs, Polar Bears, and Climate-Change Denial by Proxy” (Bioscience, 29 November 2017) fame:

Bioscience article is academic rape: an assertion of power and intimidation

Characterizing a professional, respected scientist as an unqualified vengeful opinion writer is the same kind of power attack as rape. It’s meant to humiliate and intimidate.


I said this as part of a response to a comment at WUWT late yesterday (copied in full below). The picture above shows Steven Amstrup holding polar bear cubs against their will — not for any scientific purpose, just for a photo that shows he can.

Also yesterday, Tom Fuller at ClimateScepticism wrote a hard-hitting critique of the Bioscience article that similarly noted the sexist nature of this harassment and the fact that this is the way Michael Mann and his colleagues behave toward female scientists who cross them or their supporters. He concludes:

“The purpose of these papers is not to communicate.

It is to excommunicate.”

As I said when this paper first came out, this response is all about my reasoned and fully referenced criticisms of Steve Amstrup’s work in particular (although I have taken issue with some of Stirling’s recent work as well).

The evidence that Steve Amstrup is willing to lie in order to publicly degrade me and my work in retribution for not taking everything he says as the gospel truth comes from an article at Motherboard yesterday. In it, Amstrup was quoted as saying:

 “You don’t have to read far in her material to see that it is full of unsubstantiated statements and personal attacks on scientists, using names like eco-terrorists, fraudsters, green terrorists and scammers,” Amstrup said.

I wrote Motherboard and asked for clarification that this was indeed what Amstrup said because I know it to be a lie. Check for yourself using the search function on my blog, it’s easy to do. I have never used any of those terms to refer to anyone, let alone a fellow scientist.

Late in the day, I got this response from the writer of the piece:

“Thank you for your note. A clarification has been added to the article. (my emphasis)

“You don’t have to read far in her material to see that it is full of unsubstantiated statements and personal attacks on scientists, using names like eco-terrorists, fraudsters, green terrorists and scammers,” Amstrup said. In a follow-up email on Friday, Amstrup clarified that these statements to Motherboard were meant to reflect the climate denier community as a whole, rather than Crockford in particular.

Except Amstrup specificially referred to my work. I insisted further clarification was necessary but rather than noting that I had, in fact, never used those terms on my blog, the author added this statement:

“In an email to Motherboard, Crockford denied using those terms on her blog.”

So, the author of the Motherboard piece was willing to take Amstrup’s word for an egregious accusation and when Amstrup was caught in a lie, was unwilling to make that clear. And the media wonder why they have lost the public’s trust.

However, this is all a day late and a dollar short. The cat’s out of the bag regarding Amstrup’s failed predictions. My critique (Crockford 2017) is a thorough scientific exposé of his unsuccessful model (which used assumptions based on Amstrup’s expert opinion) and people in power are taking it seriously. The Bioscience paper says more about its authors than it says about me.

Polar bears refused to die as predicted and this is how the propheseers respond

The polar bear experts who predicted tens of thousands of polar bears would be dead by now (given the ice conditions since 2007) have found my well-documented criticisms of their failed prophesies have caused them to lose face and credibility with the public.

Fig 3 Sea ice prediction vs reality 2012

Predicted sea ice changes (based on 2004 data) at 2020, 2050, and 2080 that were used in 2007 to predict a 67% decline in global polar bear numbers vs. an example of the sea ice extent reality experienced since 2007 (shown is 2012). See Crockford 2017 for details.

Although the gullible media still pretends to believe the doomsday stories offered by these researchers, the polar bear has fallen as a useful icon for those trying to sell a looming global warming catastrophe to the public.

Here’s what happened: I published my professional criticisms on the failed predictions of the polar bear conservation community in a professional online scientific preprint journal to which any colleague can make a comment, write a review, or ask a question (Crockford 2017). Since its publication in February 2017, not one of the people whose work is referred to in my paper bothered to counter my arguments or write a review.

They ignored me, perhaps hoping the veracity of my arguments would not have to be addressed. But it has not turned out that way. Now, too late, they have chosen a personal attack in the journal BioScience (Harvey et al. 2018 in press).
