Emperor Penguin
Latin name: Aptenodytes Forsteri,Conservsation status: near threatened (population is stable)
The Emperor is the largest of all penguins, standing as tall as four feet. Males withstand the Antarctic weather for up to two months without eating—keeping the eggs warm in a feathered pouch on their feet. Females travel up to 50 miles a day to bring food to the newly-hatched chicks.
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.
Other animals effected by climate change

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.

Tufted Puffins are threatened by sea level rise and storm surges which destroy habitats and breeding areas. In some areas of North America warming seas are causing the fish that the Puffins feed on to migrate farther north, making it difficult for them to find adequate food. Other threats are entrapment in fishing nets, oil spills, pollution, ingestion of plastic, human disturbance of breeding colonies and introduced predators such as rats and foxes.

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.

The annual North American migration of the Monarch is listed as a "threatened phenomenon." Climate related threats include: drought, storms, changes in precipitation and dependence on temperature to trigger migration and reproduction. The Monarch feeds and lays eggs exclusively on milkweed plants, so it is also highly vulnerable to herbicides and habitat destruction.
