Another unsupported claim of starving polar bears in Western Hudson Bay

This time it was Steven Amstrup of Polar Bears International (PBI), via a radio interview on Saturday December 28 “A Scientist’s New Job: Keeping The Polar Bears’ Plight Public.

Amstrup – co-author of the models that predict the extinction of polar bears by the end of this century – had this to say about the polar bear situation in Hudson Bay:

This year, the ice was frozen longer, so he says the bears seem to be in pretty good shape.

“But over the last two or three years, my impression has been, ‘Man, there’s a lot of skinny bears out here.’ “

On average, the sea ice in the Hudson Bay is frozen about a month less per year than it was 30 years ago. Amstrup says bears don’t eat much on land, so they lose about 2 pounds of body fat every day they’re off the ice.

“They’re 60 pounds lighter now than they might have been at this time of year 30 years ago,” he says.” [my bold]

For the last two or three years Amstrup has been seeing “a lot of skinny bears” but hasn’t taken a single photograph that he’s offered for publication or posted at PBI? Makes you wonder, doesn’t it – where are the photos of all the starving bears these guys keep talking about?

Here is a picture of a polar bear that was spending the summer on the shore of Western Hudson Bay 30 years ago, taken in July [bears were on the shore in July this year as well]. Continue reading

Kaktovik polar bear photos, again no “starving” bears

A Southern Beaufort female with cubs, from the fall of 2007. Note how fat they all are.

Note the non-starving condition.

Twenty-one amazing photos of polar bears feasting on the remains of a bowhead whale carcass outside of Kaktovik, Alaska, taken by wildlife photographer Michal Tyl, have been posted by the UK Daily Mail (December 12, 2013): Now that’s what you call a spare rib! Pack of bloody-faced polar bears spend day and night stripping a beached whale to its bones.”  Have a look and see if you can spot any “starving” bears! 

What you will see is the relative size of the bears: notice how much larger males are than females, how small cubs-of-the-year are relative to big males. Oh, and notice all the big fat polar bear butts. I can’t include any of the photos here because of copyright rules (the one above is from 2007) but I have included a map showing the location of Kaktovik, a quote from the article, and a link to my previous post on Kaktovik bears, which has a wealth of background information.

Polar bear researchers still withholding Hudson Bay data

The latest polar bear propaganda emanating from The Guardian is unscientific nonsense fed to them by activist Canadian polar bear researchers: Polar bear numbers in Hudson Bay of Canada on verge of collapse.

This episode of Goldenberg’s polar bear grandstanding includes a photo caption with a totally unsubstantiated claim that some folks might call a lie:

Melting ice is cutting polar bears off from their food source in Hudson Bay, and death rates have soared.

“Death rates have soared”? Where are all the bodies? Show us the starving bears!

In fact, the ice of Hudson Bay melts every summer and always has done. When it does, polar bears go ashore and live off the many inches of stored blubber they put on during their spring feasting on fat baby seals. The last three years, the open-water season has been only about two weeks longer than it was in the 1980s. There has been no steady increase but lots of variability.

Below I dismantle the rest of this transparently political posturing ahead of the international polar bear forum next week.

Challenging “save the polar bear” propaganda

[Updates: Note correction to point 6 and links added at the end of the post]

Polar Bears International has mustered the UK newspaper, The Guardian, to provide free publicity for a “save the polar bear” propaganda event coming up tomorrow, November 6.

From The Guardian Environment Blog:

“On Wednesday, 6 November at 10am EST and 3pm GMT you will have a chance to ask a scientist [Steven Amstrup] and a conservationist [Krista Wright] about the latest research on the state of polar bears – and the efforts to protect them.”

The “participants” of this webchat are Polar Bears International (PBI) employees. PBI is a lobbyist organization that uses its influence to pressure politicians and supposedly impartial scientific organizations, like the IUCN Polar Bear Specialist Group (PBSG), to make decisions that fit their agenda. The PBI rallying cry is “Save Our Sea Ice.They are committed to promoting legislation to curtail supposed effects of anthropogenic global warming and are using polar bears as a tool to do so.

Dr. Steve Amstrup is now a full-time, professional activist and spokesperson for PBI (Chief Scientist and Vice President”), a job he took on after a long career as a polar bear biologist. Arranging “webchats” like this is part of the job he is now paid to do.

Krista Wright has a Bachelors degree in Outdoor Education and has worked for NGOs for more than 20 years. She joined PBI in 2009 and is now the Executive Director (i.e., an administrator). She is described as “a passionate conservationist who is deeply concerned about the effects of global warming on polar bears, the Arctic, and the planet.She brings emotion to this event, not science.

Below I dissect some of the fear-mongering background presented at The Guardian, one point at a time; Guardian quotes are in italics, numbered; my responses are below, with links to pertinent previous posts that are fully referenced:

Churchill polar bear attack shamelessly used to advance global warming agenda

I guess Suzanne Goldenberg, writing for The Guardian, just couldn’t help herself with this latest story (November 4):Polar bear attacks: scientists warn of fresh dangers in warming Arctic. Two people injured in latest attack as hungry bears deprived of access to sea ice increasingly look for food on land.

Reporting on the attack is one thing — several papers covered this over the weekend (see Featured Quote #46, posted yesterday, for links to two of them). However, Goldenberg shamelessly makes this about global warming, aided and abetted by Polar Bears International (PBI) representative Steven Amstrup, a claim that doesn’t hold up to even minor scrutiny.

Polar bear cannibalism and sea ice, the spring of 1976

Remember Ian Stirling’s claim that late freeze up in Western Hudson Bay in 2009 was forcing polar bears to resort to cannibalism (here and here), with gut-wrenching images and video provided for the media? Or Steve Amstrup’s claim for a similar phenomenon in the Southern Beaufort in 2004?

I pointed out that Stirling’s claim was way overblown and that Amstrup’s incidents were almost certainly the result of heavy ice in the spring (not low ice in summer), similar to the heavy ice conditions and polar bear starvation documented in the same region back in 1974-1976.

It turns out that the heavy ice conditions documented in the Eastern Beaufort in the mid-1970s had much broader effects on polar bears and ringed seals than has been appreciated.

Cannibalism update and insight on the timing of media hype

In my last post, I went over some of the spin and misrepresentation of fact contained in the claim by leading polar bear biologists Steven Amstrup, Ian Stirling and Andrew Derocher (Amstrup et al. 2006; Stirling and Derocher 2012) that cannibalism is on the increase because of the effects of global warming on Arctic sea ice.

I’ve had an opportunity to follow up on three points that puzzled me. Three relate to the Amstrup et al. paper that described three cases of cannibalism in the southeastern Beaufort Sea in 2004 and one to the incidents in western Hudson Bay in 2009. In the process, I found at least three more misrepresentations of fact and gained some insight on why these incidents of cannibalism were hyped so enthusiastically when they were. Continue reading
