Here’s a climate-change impact you don’t think about every day: trampled walruses. When walruses get tired of swimming, they clamber onto sea ice to rest. As ice is in increasingly short supply above the Arctic Circle, walruses are huddling on shore in extremely high numbers. And as the tusky animals are liable to stampede at the appearance of a polar bear, hunter, or low-flying airplane, more than 3,000 walruses are estimated to have been trampled to death by their panicky brethren this past year. Let that be a lesson to us all. Or something.
