Ocean Acidification Climate change’s equally evil twin seems to be ocean acidification. 25 percent of the CO2 dissolves into the ocean instead of being in the air. When the industrial era started over 525 billion tons of CO2 were absorbed (22 million tons per day). Scientists at first thought that we were good because it warms the planet‚ but that’s not the case. The ocean is becoming more acidic than ever because of the CO2. 200 years later the water temperature increased by 30 percent. Rivers usually

were all of a sudden gone? According to studies‚ this is what could happen by 2050. On this rate‚ calcifiers will become less and less due to the carbon dioxide mixing with the water to make carbonic acid which breaks down into hydrogen gas and bicarbonate ions.

dioxide is a toxic waste product generated in the oxidation of fats‚ carbohydrates and proteins within the cells. The gas itself is not an acid‚ but it reacts with water to form carbonic acid which then dissociates to form a hydrogen ion and a bicarbonate ion: CO2+H2O↔ H2CO3↔H++ HCO3- The respiratory system helps to control the acidity of
