The Beaufort Sea is one of three areas most disturbed by global warming.

Arctic Changes: The Decisive Moment at Baffin Island (8:39)

The crew has been advised of the concentration of ice ahead of them; they must face 1 mile of ice before it clears. The conditions to be faced are ones they had hoped to avoid, so they must decide whether they will turn around or continue.

Arctic Changes: The Sedna Faces Ice at Baffin Island (8:48)

At Baffin Island, the expedition will again face ice. Isabella Bay gives the biologists much to observe.

Ice Mountain (0:26)

What does it take for a river to freeze over completely? Find out in this clip from the archives of Discovery.

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: Weather Changes Invite Parasitic Infection (3:05)

Due to changing weather patterns, Arctic species have an increased risk of parasitic infection.

Wild Arctic: Global Warming Affecting Hudson Bay Birds (8:29)

The Canadian Wildlife Service has been studying birds in the warmest portion of the Hudson Bay. These birds are showing the effects of global warming.

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.

Wild Arctic: The Polar Bear's Plight (2:54)

The polar bears are facing a major threat from global warming. They have to swim farther between ice floes from which they hunt, and the ice floes are disappearing early.

Wild Arctic: The Caribou's Summer Calving Grounds (1:58)

The short Arctic summer allows the caribou to travel to their calving ground at a time when the plants are most nutritious.

Wild Arctic: Global Warming and the Bowhead Whale (5:14)

The effect of global warming on the bowhead whale is discussed in this section.
