The walrus may have more to fear from global warming than polar bears. Both are tied to the sea ice in the Arctic that has been melting every summer at record paces.
Like the polar bear, the walrus often finds itself too far out to sea to swim safely back to shore when the ice melts. Perhaps thousands drown every year. Many more reach shore, only to die in stampedes that are triggered when walruses get spooked.
It’s the walrus’ unique, but fatal, reaction to global warming.
