Posted onAugust 29, 2018|Comments Off on White Lie: Polar bear starvation is virtually never caused by sea ice loss
Starvation due to natural causes is the leading cause of death for polar bears and loss of body condition (getting thinner) is therefore the first symptom of impending death for virtually all polar bears that die naturally. However, polar bear specialist Andrew Derocher claims that loss of body condition is also thefirst symptom of climate changefor polar bears.
But how do you tell the difference between polar bears made thin by man-made climate change and those who are thin due to natural causes?
You can’t. Even a necropsy will not be conclusive because there are so many natural reasons for a bear to lose weight — and even starve to death — that’s it’s virtually impossible to say that any thin bear is skinny due to a lack of sea ice.
Emaciated polar bears like the one above from Somerset Island in the Canadian Arctic,1 captured on camera in August 2017, are being used to promote the idea that polar bears are already dying of starvation due to climate change. That’s a big white lie, as the headline above suggests: seven months later, National Geographic has admitted as much. Here I show why it could not have been true in the first place (with references from the scientific literature).

Posted onJuly 30, 2018|Comments Off on Churchill problem polar bear report for week 3, July 23-29 2018
Polar bears that have come off the sea ice of Hudson Bay near Churchill, Manitoba in Western Hudson Bay are apparently in a wide variety of conditions, from very fat to skinny. So, not all skinny despite the relatively early breakup of ice in the northwest.
Most of the ice was gone from the NW of Hudson Bay for the week of 23 July 2018 and the graph below shows that this is a new pattern that began in 1997, with only 2009 being an outlier:
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?
