    The ocean also absorbs some of the extra carbon dioxide that is in the atmosphere. This causes the pH value of the seawater to drop. [4] Scientists estimate that the ocean absorbs about 25% of all human-caused CO 2 emissions. [4] The various layers of the oceans have different temperatures. For example, the water is colder towards the bottom of ...
