In this part of my critique of Stirling and Parkinson (2006), regarding breakup dates in Western Hudson Bay (see Part I here), I will show that these authors also left out critical data.
Figure 1. A bear is transported to Churchill’s polar bear holding facility, from a 2011 Huffington Post article “Polar Bear Prison.”
Their correlation between number of problem bears in Churchill and breakup dates for WHB worked because some very inconvenient data were simply left out: problem bear data for 1983 and 2004.
Inclusion of that information would have shown 1983 and 2004 were two of the worst years for polar bear problems in recent history despite being late breakup years (1983 also had the last human fatality from a polar bear attack). They could have explained why they did not use the data but they did not — they simply left it out.
Amazingly, this work is being touted as “evidence” that global warming is harming Western Hudson Bay polar bears.

While I was in London, ahead of my House of Lords lecture on June 11, 2014 (“Healthy Polar Bears, Less Than Healthy Science“)*, I had a chat with Benny Peiser of the Global Warming Policy Foundation.
Have a listen here: “An Interview with Dr Susan Crockford on polar bears, evolution and Arctic controversies.”
I’ve been traveling for a month but I am finally home — tired and jet-lagged after a journey that took me two-thirds of the way around the world and back. More on my experiences as my energy for blogging returns.
*I shouldn’t have to point this out but I will: I was not paid for this lecture, nor for the airfare to London (I was passing through town anyway). As the timing of the lecture required an overnight stay, GWPF did pick up the tab for a hotel room and dinner, as hosting organizations for such events do as a matter of course.
