Staghorn Coral

Coral reefs are the most diverse ecosystems in the marine world and can take 10,000 years to form. They cover less than 1% of the ocean floor but are habitat for at least 25% of all known marine life. A coral is made up of thousands of tiny animals called polyps, protected by a hard skeleton. There are 160 different species of 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.

Other animals effected by climate change

Tufted Puffin
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.

Hawksbill Sea Turtle
Climate change may affect Hawksbill Turtles in various ways because they live in different habitats at different stages of life: open ocean, beaches, lagoons and coral reefs. Rising sand temperature of nesting beaches produces more females and other abnormalities in baby turtles. Adults live primarily in coral reefs—threatened by rising ocean temperature and acidity. Since ancient times the Hawksbill has been exploited for its shell. They are also threatened from fisheries by-catch, development, and a high sensitivity to oil spills. The population has decreased by an estimated 80% in the last 100 years.

Rusty Patched Bumble Bee
The Rusty Patched is the first bee to be listed as endangered in the US. Populations have declined as much as 87% from habitat loss, disease and pesticides. Climate threats include: warming and precipitation, early snow, late frost and drought. Bees and butterflies are important agricultural pollinators. In 2016, 40% of invertebrate pollinators (bees and butterflies) were listed as threatened with extinction.

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.
