Threats
 


Climate change poses a major threat to all ecosystems on earth, including our oceans.

As the average global temperature increases, so will the temperature of our waters. Already, the polar ice caps are melting at an alarming rate, with a chunk of Antarctica the size of Rhode Island recently set adrift at sea.

As temperatures warm, Artic sea ice will melt, destroying habitat for many arctic species – for example, polar bears, who traverse the ice in search of food. Also, temperature will increase more at and around the poles. With such an increase in temperature, wildlife and ocean currents will be affected. Coastal areas will be threatened or destroyed as ocean levels rise. Storms will worsen, further threatening the coasts. Coral reefs worldwide will face death from the heat, and many low-lying islands based on coral atolls will be drowned.

"Such high rates of change will probably result in local if not total extinction of some species, the alteration of species distributions…and modifications in the flow of energy and cycling of materials through ecosystems" (Oceana, 2005).

We need to start tackling the climate change issue now in order to save our ecosystems for the future.
