You can look up the polar bears yourself. You'll find that the population now is about 4-5x the population in the 60s. It may be decreasing slightly in the past few years, but that's in the noise compared to the recent increases. There's no reason to suspect temp change has had an effect comparable to direct intervention by humans.
With respect to the polar bears, I searched around and found many articles which state that the population in the 60's had been diminished because of hunting and that, currently, the plurality of polar bear populations are in decline because of climate change. The one article I found that supports your argument was from Fox News (no bias there ;-)).
I note that you didn't mention the relative sizes of these changes, the former being >4x while the latter is close to the margin of error.
Then again, doing so doesn't fit your beliefs.
I'm not looking to do battle here. In fact, I thought I was being humorous and polite. Moreover, I'm happy to see that the polar bear situation is not as dire as I thought. I've adjusted the thermostat in my apartment accordingly.
I did. Hunting is part of "direct intervention by humans". Habitat is another.
