Wild Arctic: Desperate Caribou on Thin Ice (5:39)

The caribou must wait for things to freeze up before heading for the mainland. As the time grows later and later, caribou are forced out on to thin ice.

Wild Arctic: Caribou Migration and Climate Change (2:15)

Dolphin and Union caribou migrate in the fall. They are experts at living in the snow, but if the snow hardens due to climate change it will make their ability to find food all the more difficult.

Wild Arctic: Barren Ground Caribou on the Tundra (3:33)

The barren ground caribou are an important part of the food web in the Arctic tundra. Increased heat from global warming means they will feed less and consequently reproduce less.

Wild Arctic: Weight Loss Amongst Arctic Walruses (0:55)

As the ice cover decreases, walruses are also affected. They use the ice floes as feeding platforms, but increased melting of these surfaces forces them to swim farther and longer. This has led to weight loss in the walrus population.
