Well, not really. Polar bears live in the Northern Hemisphere. (Here's a riddle: why won't a polar bear eat a penguin even if the bear is starving? Answer: they live in different hemispheres.)
Except penguins lived in the Northern Hemisphere: https://en.wikipedia.org/wiki/Great_auk. Great Auks are the original "penguin". What we call penguins today are not actually in the genus Pinguinus.
Oh, you climate alarmists and your "scientific facts." Why do you hate freedom?
