Polar Bear
Latin name: Ursus Maritimus,Conservsation status: vulnerable (population is unknown)
Although it looks white, Polar Bear fur is actually transparent and hollow and traps heat from the sun. The skin under their fur is black and absorbs the sun's heat. They also have a thick layer of fat so overheating can be a bigger problem than staying warm. Polar Bears can swim 6 mph—up to 100 miles at a time—and run as fast as 25 mph.
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.
Other animals effected by climate change

Koalas live in the woodlands of Australia. Thick fur and skin make it difficult for them to adapt to rising temperatures. Increased CO2 in the air produces less protein in the eucalyptus leaves, forcing the Koala to search for other sources of food and, in times of high heat, water. On the ground, the slow moving Koalas are prey to wild dingoes and domestic dogs, or are hit by cars as they cross roads. Their habitats are also being destroyed by drought, bush fires and development.

Clownfish live in the shallow waters of coral reefs where they have a mutually beneficial relation with a few species of sea anemone. The anenome protects the Clownfish, and the fish's swimming aerates the water around the anenome. Clownfish are unable to move long distances, and rising ocean temperature and acidity is a threat to their coral reef habitats. Increased acidity also seems to impair their ability to navigate to their home anemones.

In 50 years, the mean temperature of western Antarctica has risen nearly 3 °C—more than any other region—reducing the extent and thickness of winter ice. The Emperor Penguin is dependent on the ice for breeding, raising chicks and moulting. Less sea ice decreases zooplankton (krill) which feed on algae that grow on the underside of the ice. Krill are an important part of the food web for the Emperor and other Antarctic marine species.
