Retraction request to Bioscience: FOIA emails document another harsh criticism of Amstrup’s 2007 polar bear model

Today I sent a letter to the editors of the journal Bioscience requesting retraction of the shoddy and malicious paper by Harvey et al. (Internet blogs, polar bears, and climate-change denial by proxy) published online last week.

The letter reveals information about the workings of the polar bear expert inner circle not known before now, so grab your popcorn.

I have copied the letter below, which contains emails obtained via FOIA requests to the US Geological Survey and the US Fish and Wildlife Service by the Energy and Environment Legal Institute, E&E Legal, and the Free Market Environmental Law Clinic (USFWS request; USGS request) and sent to me by lawyer Chris Horner in 2014, unsolicited. I reveal some of them now, with his permission (most of the emails are boring, involving mostly technical topics not relevant to anything, as might be expected).

The emails in question, sent in 2014, pertain to preparations by three members of the Polar Bear Specialist Group for the IUCN Red List assessment due in 2015 (Kristin Laidre, University of Washington, Eric Regehr, US Fish and Wildlife Service, and Østein Wiig, Museum of Natural History, University of Olso), and Steven Amstrup (formerly head of the polar bear research at the US Geological Survey, now “head scientist” for conservation organization Polar Bears International.

They include frank discussions about a harsh critique of Amstrup et al.’s 2007 report and 2008 paper used to support listing polar bears as ‘threatened’ on the US Endangered Species List. The criticisms come from modeling expert and chair of the IUCN Red List Standards and Petitions Subcommittee (which develops guidelines for threatened and endangered species assessments, and evaluates petitions against the red-listing of these species), H. Resit Akçakaya. The IUCN is the world’s leading conservation organization, of which the PBSG is a part.

These records are a damning indictment that the “best available science” was not used to assess conservation status of polar bears under the ESA in 2008 and 2014 and show that I am not the only scientist who thinks Amstrup’s model is fatally flawed. The letter is copied in full below, the emails are copied at the end. A file of all of the entire pertinent email thread is available as a pdf below. Here’s a sample:

USGS polar bear researchers publish their rebuttal to 2015 IUCN Red List assessment

Surprise! US Geological Survey polar bear specialists have just published another opinion-based model that concludes – yet again – that there is no hope for polar bears of the future unless the world drastically reduces fossil fuel use. This appears to be the Amstrup-led rebuttal to the hated 2015 IUCN Red List polar bear assessment I have been expecting, written in tandem with the Red List document by two of the same co-authors (Steve Amstrup and Todd Atwood).

Really, no surprises here – just more of the same overwrought fear-mongering about polar bears that we’ve been hearing from USGS since 2007. I saw Atwood and Amstrup last week in a British-made TV film that expressed the same sentiments (The Great Polar Bear Feast – it oddly featured dozens of fat/very fat Kaktovik polar bears while mostly USGS ‘experts’ talked about impending starvation). On camera, Atwood and Amstrup were almost indistinguishable in their statements of doom, and even though the film aired 6 months ago in the UK, it has so far not garnered the angst it seems to have intended.

Some folks may be even more convinced than ever by this new PR strategy [TV movie plus a published paper] that the polar bears are all going to die unless we (not they) change our wicked ways and stop using fossil fuels, but chances are that many more will detect the desperation in their escalated pitch and continue to refuse to buy what they are so frantically trying to sell.

Polar bear doom and gloom from USGS vs. biologist Mitch Taylor’s reasoned thoughts

A few days ago polar bear biologist Mitch Taylor and Nunavut’s Gabriel Niryungaluk talked to Toronto radio host Roy Green about the recent USGS dire model predictions for the future of polar bears.

USGS promotes another flawed polar bear model: GHG emissions still “primary threat”

It’s still based on the same flawed ecological premise as all previous models – it assumes that sea ice was a naturally stable habitat until human-caused global warming came along. It also uses slight-of-hand maneuvers to correlate declining summer sea ice and declining polar bear population numbers.

Just because they keep repeating the same hype doesn’t make it true.

Polar bear biologists try – again – to blame S. Beaufort thick spring ice on global warming

The trouble is, sea ice researchers and atmospheric scientists have not drawn that conclusion, despite what a new paper by Pilfold and colleagues imply. It shows just what lengths desperate IUCN Polar Bear Specialist Group  (PBSG) biologists will go to in order to link the recent decline of Southern Beaufort bear numbers to global warming while ignoring similar past declines.

Faux polar bear figures – my editorial in the National Post

Published in the Business section (Financial Post “Comments”) of the National Post this morning:

“Faux polar bear figures” [not my choice of title, by the way]

In which I conclude:

We admire polar bear biologists for their professional dedication to this iconic species, and rightly so. However, while it’s understandable that polar bear biologists are conservation-minded, the public and policy makers need them to be scientists first and advocates for polar bear protection second. Polar bears are currently doing well – data shenanigans to keep them classified as “threatened” undermine the whole point of doing science.”

I have written extensively about the Southern Beaufort issue — below are links to some of these, which have links to the rest. References are included in these individual posts. Contact me if there is a reference you cannot find: Continue reading

‘Threatened’ status for Arctic ringed seals under ESA makes no sense

Recent research (Crawford and Quakenbush 203; Rode et al. 2014) has shown that sea ice declines in the Chukchi and Beaufort Seas have made life better for ringed seals, not worse (as predicted) – ringed seals are in better condition and reproducing better than they were in the 1970s. Why? Ringed seals do most of their feeding in the open-water period (Young and Ferguson 2013), so a longer open-water season means fatter, healthier seals and more fat pups for polar bears to hunt the following spring.

However, Arctic ringed seals (as well as bearded seals) were designated as ‘threatened’ by the USA in 2012 under the Endangered Species Act, based on predicted ice and snow declines due to prophesied global warming. These listings are all about future threats, with no pretense of on-going harm.

Virtually no other Arctic nation has taken this step for Arctic seals — see previous discussion here. There are lots of ringed seals — an estimated 3-4 million world-wide and about 1.7 million within the critical habitat proposed by NOAA (see below).

As weak as the case for listing polar bears as ‘threatened’ has proven to be, the case for listing ringed and bearded seals is even more feeble (a judge has already sent the bearded seal listing back to the drawing board).
