No evidence of actual damage to polar bear brains from environmental contaminants

Earlier this year we had polar bear penis bones supposedly breaking due to environmental toxins; this week we have their brains damaged.

The March 15 ScienceNordic story (“Chemical pollution is causing brain damage in polar bears”) came complete with a photo of a bear (copied below, provided by research co-author Rune Dietz) that is presumably meant to convey what a “brain damaged” polar bear might look like — if not, perhaps another photo would have been a better choice?

Except, the research only showed there theoretically might be damage but the researchers didn’t bother looking for it before shouting out their findings. All about the scary message, these folks: the very large uncertainties and speculation in their research be damned.

PolarBearScience has been ‘Carbon Briefed’ – success at last!

Not just anyone warrants the attention of the European rapid response team: only those who get media attention and refuse to stay ‘on message’ about global warming issues get the Carbon Brief treatment.

After years of being ignored, I have finally been acknowledged as a worthy adversary [a force to be reckoned with] by those who spin the science of polar bears.

Carbon Brief folks got their knickers in a knot over my “Twenty Good Reasons Not to Worry about Polar Bears” blog post that the Global Warming Policy Foundation released as a Briefing Paper (pdf here). All timed for release on International Polar Bear Day (27 February 2015), which got mainstream media attention galore in the UK.

Twenty good reasons not to worry about polar bears

PB  logo coloured Here’s a new resource for cooling the polar bear spin, all in one place. I’ve updated and expanded my previous summary of reasons not to worry about polar bears, which is now two years old. In it, you’ll find links to supporting information (including previous blog posts of mine that provide background, maps and extensive references), although some of the most important graphs and maps have been copied into the summary. I hope you find it a useful resource for refuting the spin and tuning out the cries of doom and gloom about the future of polar bears — please feel free to share. Pdf here of the text below.

This is the 1st anniversary of Canada providing population estimates and trends independent of the pessimistic prognostications of the IUCN/SSC Polar Bear Specialist Group (PBSG) — so let’s celebrate the recent triumphs and resilience of polar bears to their ever-changing Arctic environment.

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.

East Greenland polar bears – said to be the most polluted but appear to be doing just fine

I’ve not written much about this subpopulation before but with the flurry of interest over “weakened” penis bones and toxic chemicals, I thought it was time to remedy the situation.

Editorial calls for more jobs for polar bear biologists

An editorial in the Edmonton Journal this morning (“Stand on guard for polar bears”) takes a most extraordinary position: that the results of two recent papers of dubious value should motivate Canada to create more jobs for polar bear biologists, “protect” the Canadian Arctic Archipelago (from what, they don’t say), and galvanize Canada’s position with respect to curtailing carbon dioxide emissions. In that order.

First, the unnamed editors1 say: “This country needs more eyes and ears monitoring the health, numbers and locations of its polar bear populations.

Why would they come to that conclusion? They quote University of Alberta’s Andrew Derocher (who supervises a number of students doing polar bear research in Western Hudson Bay):

“If Canada was doing the right thing, we’d have extensive monitoring,” University of Alberta polar bear researcher Andrew Derocher said to the Journal in late 2014.

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
