Arctic Fox

With fur on the bottom of their feet (vulpes lagopus means "hair-footed fox"), reserves of fat, the ability to slow their metabolism when food is scarce, and a thick coat that changes from white to brown or gray with the season, Arctic Foxes are especially adapted to the tundra.

The Arctic tundra is a region of shrubs, grasses and permanently frozen subsoil. Warming could change the tundra to boreal forest—habitat for the Red Fox. The Red Fox, a predator and a competitor for food, is already beginning to migrate north into the Arctic Fox's territory. Milder tundra weather also causes changes in the population of lemmings and rodents—main food for the Arctic Fox.

Other animals effected by climate change

Shenandoah Salamander
The Shenandoah Salamander lives in an isolated, high altitude region of Shenandoah National Park, USA. Like all amphibians who have thin, permeable skin, salamanders are very sensitive to environmental changes. If average temperatures or moisture increase, this salamander, restricted to its cool micro-climate, will be at risk—having no place to go but to lower, even warmer, altitudes. If warming causes other species of lower altitude salamanders to migrate higher, they will compete for the Shenandoah's cool, moist habitats.

Polar Bear
Polar Bears live only in the Arctic. Loss of sea ice has a critically adverse effect on Polar Bears. They hunt from the edge and build snow dens on the ice for resting and raising their cubs. Sea ice decline could open the Arctic to shipping and tourism, further disturbing Arctic habitats. Other threats are oil development and industrial pollution that reaches the Arctic through air and ocean currents.

Leatherback Sea Turtle
Climate change impacts the Leatherback in two main ways: an increase in the temperature of nesting sands causes a greater proportion of females to hatch, destabilizing future populations; and sea level rise and stronger, more frequent storms erode nesting beaches and wash away eggs and hatchlings. The Leatherback is also threatened from fisheries by-catch, egg collection, coastal development, pollution and ingestion of floating plastics.

Narwhal
The Narwhal lives mainly in the Atlantic Arctic. Because of specialized habitat, narrow range and limited diet (Arctic cod and halibut), it is one of the Arctic species most vulnerable to climate change. The Narwhal breeds in bays and fjords, moving offshore during winter to areas of heavy ice pack, breathing through the few cracks. Sudden or extreme temperature change can cause these cracks to freeze shut, trapping the whales. Other threats are illegal hunting, industrial activities, and risks from oil development, exploration and shipping in the Arctic.
