Latin name: Phascolarctos Cinereus,
Conservsation status: vulnerable (population is decreasing)

The Koala is not a bear, but a marsupial. Like the kangaroo, it carries its young in a pouch. It rarely drinks water—Koala means "no water" in native Australian. Its water and food come from eucalyptus leaves, which are water rich but nutrient poor. To conserve energy, the Koala naps up to 20 hours a day and stays up in its home trees most of the time.

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.

Other animals effected by climate change

Bramble Cay Melomys Bramble Cay Melomys
The Bramble Cay Melomys was the first species to be declared extinct because of climate change. Sea level rise and storm surges washed away its habitat, food and the last of the population. In 2014 scientists went searching in the hopes of starting a breeding program but were unable to find a pair. Other sea birds and turtles that live on the Cay are also threatened by storm surges and sea level rise.
Staghorn Coral Staghorn Coral
In the last 30 years the Staghorn Coral population has decreased by 80% from disease, pollution, development and damage. Climate change is increasing the risk of extinction. Corals live in symbiotic (mutually beneficial) relation with algae. The coral receives nutrients and oxygen from algae, and the algae receive nutrients and carbon dioxide from the coral. Rising sea temperature increases algae growth so oxygen levels become too high for the coral, causing "bleaching"—the coral expels the algae and dies. Higher ocean acidity contributes to bleaching and also reduces the ability of corals and other marine animals to build hard shells. Other threats from climate change are sea level rise, changes in currents and storm damage.
Common Clownfish Common Clownfish
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.
Western Glacier Stonefly Western Glacier Stonefly
Since 1960, the average summer temperature in Glacier National Park has increased by around 1 °C and glaciers have declined by 35%. By counting Stoneflies, scientists can determine how quickly glaciers are melting and the temperature of streams. In a two year search begun in 2011, scientists found the Stonefly in only one of the six streams it had previously occupied and discovered that it had retreated to two different streams at higher altitudes. Satellite data confirm that the world’s glaciers are declining, affecting the availability of fresh water for humans, animals and plants, and contributing to sea level rise.
