I did my best to get away from work last week while my family and I were on vacation visiting friends who live in Kalispell, the gateway to Montana's Glacier National Park. But it wasn't quite possible. You see, I'm a climate scientist. And the spectre of climate change stares you in the face as you tour the park.
Of all the projected nightmare scenario effects of global warming, one has seized my imagination like no other. I cannot erase the image of a lone polar bear standing on an island of ice barely bigger that it is, floating alone in the Arctic Sea. Drifting toward certain death by starvation or drowning.
