Ocean Acidification The main theme of the 3 articles is that the ocean is becoming more acidic due to fossil-fuel emission of CO2. The ocean has absorbed about 525 billion tons of carbon dioxide from the atmosphere‚ this reduces the amount of greenhouse gas in the atmosphere (1). ). It is lowering the pH by .1 units changing it from 8.2 to 8.1… it is becoming more acidic. (2). It happens when the CO2 from the air mixes with the sea water‚ it produces a bicarbonate ion. This bicarbonate ion then
