A higher ocean surface temperature has caused a loss of polar ice, especially in the arctic. It has also increased the incidence of cyclones, which are caused by differentials in temperature. The melting of polar ice and thermal expansion have caused a rise in sea level by 10 to 20 cm during the last century. This increases flooding risks and increases the rate of beach erosions. Islands may be completely inundated. Since half the world's population lives near coasts and small islands, this is a serious issue. The higher surface temperature is especially damaging to coral, which relies on algae for its food. The higher temperature kills the algae can causes bleaching of the coral, which is habitat for many species of fish.

On land, global warming is believed to have increased the severity and frequency of droughts since the 1970s, especially in the tropics and subtropics. Glaciers and snowpacks have also declined. Species adopted to specific ecosystems are finding their habitats moving or disappearing. Animals which cannot locate suitable habitat quickly die.

Oceans are naturally alkaline but become less alkaline as CO2 levels increase. This lowers the concentration of carbonate ions, making it increasingly difficult for many marine organisms to create skeletal structures. Coral, for example, is greatly affected because it must build faster than erosion can wear it ...
