The two top posts I published this year had one thing in common – they exposed polar bear researchers dodging full disclosure of scientific information in a way that outraged a lot of people. These two posts still draw a regular crowd of readers.
#1. “Global population of polar bears has increased by 2,650-5,700 since 2001” (published July 15, 2013) – 8,786 views as of December 30.
#2. “Ian Stirling’s latest howler: the polar bear who died of climate change” (August 7, 2013) – 7,872 views as of December 30.
[Note that #3 was the summary essay, “Ten good reasons not to worry about polar bears” (February 26, 2013), at 5,491 views. Dr. Matt Ridley wrote a foreword introducing that essay (“We should be listening to Susan Crockford”) that appeared in Canada’s Financial Post]
On this last day of the year, I thought I’d make an attempt to put these results into a wider perspective.
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
Warmest regards and heartfelt thanks for your support over the last year. Have a wonderful holiday.
With the winter darkness in the Arctic comes the splendor of the Northern Lights — Aurora Borealis.
Yesterday, a short video clip of photographer Thomas Kast’s time-lapse Northern Lights video “Aurora – Queen of the Night” was posted at Alaska Dispatch, Time-lapse images show northern lights over Finland. There are no polar bears in the film but it is evocative of Arctic landscapes this time of year — when only the Northern Lights and the moon brighten the sky: Continue reading
From the end of October to mid-December, there has been a rapid expansion of polar bear habitat.
This month, I’ve constructed two all-in-one images that show the progressive growth of the ice relative to some critical polar bear onshore summer refuge areas and denning territory. I’ve also included a map that compares 2013 to 2009 at 18 December with the average for the 1980s, and one that shows ice thickness.

Ironically, just as I was about to remind readers that we are entering the peak period of polar bear births around the Arctic (see previous post, “December is polar bear nativity month”), I came across an article about breeding polar bears in captivity — getting the bears to give birth in zoos.
Hudson the polar bear cub is a zoo-born polar bear. He moved in January 2013 from the Toronto Zoo, where he was hand-raised after being rejected by his mother, to the Assiniboine Park Zoo, Winnipeg. The Assiniboine Park Zoo were also the recent recipients of a cub orphaned when its mother was shot after a polar bear attack in Churchill. Photo from Toronto Zoo.
The newspaper article I saw was all about how technically difficult the generation of polar bear cubs has been for the Toronto Zoo (Canada) but it was the premise for the breeding program itself that caught my attention: to save them from extinction.
The zoo is not waiting until the bears are down to the last few hundred (or even thousands) – no, the zoo is starting now, while polar bears are as plentiful as they have been in the last 40 years, to prepare for their demise.

A Southern Beaufort female with cubs, from the fall of 2007.
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.
