The oceans absorb around 30% of carbon dioxide (CO2) released into the atmosphere as a result of human activities.
It seems that the different carbon levels are measured in different depths. And the waters’ ability to absorb carbon depends on the temperature differences. As CO2 dissolves in seawaters it forms carbonic acid, decreasing the ocean’s pH. This is called ocean acidification. 50% of marine life is expected to be affected by ocean acidification. Its impact is now visible on coastal protection; ocean acidification weakens coral reefs shielding the coast line – another good reason to decrease CO2 emissions.
