During the months of summer when the ice retreats, this lethal game of whack-a-pinniped is hard to play and the bears have been assumed to rely instead on the layers of fat they accumulate during the winter. This has led some conservationists to conclude that the species will run into in trouble in the future as global warming melts the Arctic's sea ice ever earlier and reduces the time bears have to replenish their fat stores. But a new study suggests that seal is not the only thing in the bears' larder. They may be able to supplement it with a summer diet of geese, and thus evade the consequences of a changing climate.
