The Arctic is heating up faster than anywhere else on the planet and polar bears and walrus are showing signs of starvation as the sea ice on which they depend melts away. The Arctic is on the front-line of global warming. The western Arctic is already warming three to five times faster than the global average. The Arctic ice pack has shrunk dramatically over the past 40 years. Ice thickness has declined by more than 40 percent and an area the size of Texas has disappeared in the last 20 years.
Marine mammals are under threat as the ice pack on which they hunt and breed melts away.
