As the NATURE episode Invasion of the Killer Whales showed, climate change is beginning to have an impact on animals that live in the Arctic, one of the coldest regions on earth. Seasonal ice sheets, the main hunting grounds of polar bears, are vanishing. But an ice-free Arctic is opening up new food sources for killer whales.
