Global warming can affect negatively the oceans in three differentways. Firstly, it affects oceans by rising the sea level. As the globalwarming is increasing the glaciers, for example, in Greenland and Antarcticice sheets are melting. So, the water's volume expands and the sea levelrises. Secondly, it influences oceans by increasing the ocean'stemperature. The high temperature of the ocean affects the ecosystem bymelting sea ice, affecting algae that grow in the sea and reducingthe ocean's ability to absorb CO2. Thirdly, it affects oceans throughincreasing the ocean's acidification. Carbon dioxide which is producedby the living organisms in the oceans becomes carbonic acid. Scientistsbelieve that increase of acidification could have a negative impact on marine life. It badly affects the coral reefs, calcium carbonateshells, fish and plankton. The number of these organisms is decreasingday after day because of global warming.
