Oceans are a huge thermic mass that gets easily warm but with difficulty colds off. Carbon dioxide melts in the oceans which become acid, causing problems to organisms. CO2+H2O H2CO3 H+ + HCO3

If the oceans heat up, there will be a rise in the atmosphere of carbon dioxide and of methane, two of the most dangerous greenhouse gases.
