I would think that thin polar bears means LONGER winters. A polar bear could eat more and obtain more fat in warmer climates...........

Polar bears hunt seals. They have to be on the ice to do that. Longer winters mean more time to catch and eat seals.

I'm confused. In northern climes, I have seen plenty of seals when there wasn't any ice. Also other kinds of bears hibernate in the winter, when they come out of hibernation in the late spring, they are very thin. You are saying that polar bears do the opposite?
