Happy Polar Bear Day!

Every year on this day, I check on the status of polar bears. This past year, we learned polar bear cubs look very cute when they hitch a ride, and that their purple tongues are very, very long.

Cute, yet vicious, my favourite of bears are a marvel of physics. Did you know they retain heat so efficiently that in infrared, you can only see between their toes and the tip of their noses? Amazing!
