The results are disturbing.

You mean the theoretical results? The actual data raises questions about polar bear habitat and human ignorance about polar bear behavior, but it makes me wonder what polar bears did in the last interglacial warming cycles (e.g. Holocene optimum) where the polar ice receded? Like most limited habitat species, I expect they adapt or if they are too niche then they die off. I highly doubt they survived for so long without a strategy for warmer weather.

I'm looking at this site, which shows if I'm not mistaken, that while there is an ebb and flow in polar ice, that mostly it snaps back to near normal. The polar ice cap fluctuated between 5 and 14 million sq km in 1980, and slowly erodes to between 4 and 13 today. There appears to be a loss of about (on average) 1 million sq km, but you might expect that at the end of a global cooling cycle.
