 Finally she leaves him some scraps 1 to chew on. A young male arrives, a dangerous situation for the cub 2. She growls 3 a warning. It’s not enough. The cub slips. The mother must get her cub away from danger as quickly as possible.


They head north. She knows that this is where the ice, and with it the seals will first return.
It’s now September, but the sea might not freeze again for another two months. Her cub is unlikely to survive that long.
But there is hope on the horizon. An ice-rainbow heralds 4 change. In the far north, temperatures drop at last. And ice sheets start to grow rather than disappear.
Then a miracle happens, building pressure combines with powerful southerly currents to push the drift-ice southwards.
