Carbon, or carbon dioxide, concentrations in the atmosphere have increased. The burning of fossil fuels is the cause of the increase in carbon or carbon dioxide concentrations in the atmosphere.
More CO2 is dissolving into the ocean as a result of increased levels of carbon dioxide in the atmosphere caused by humans. The average pH of the ocean is now around 8.1, which is basic (or alkaline), but as the ocean absorbs more CO2, the pH drops and the ocean becomes more acidic.
