I once (about forty years ago) was trapped on the Robinson Glacier, east of the one in the video. Spent three days and two nights down in a crevasse, riding out a horrific blizzard. You really can eat mountain house meals "dry" right out of the bag. After you get hungry enough, and you figure you are going to die on the glacier anyway, what the hell, may as well go out with a full stomach.
Yep, but someone forgot to tell the glaciers and bears. The polar bear population has grown about 300% and the glaciers are in another growth period. It's about time to move to the ice age story about now.
Maybe they will switch to alien invasion of planet Earth. That is easier to fake than a meteor headed for our planet.
