There are numerous other issues raised that relate to global warming. One of them is the acidification of the ocean (ocean acidification) adding co2 in the atmosphere increases the co2 dissolved in seawater co2.Which makes the ocean more acidic. Studies estimate that the ph at the sea surface when the industry started with the 8.25 and dropped to 8.14 in 2547 estimated that the ph will drop at least 0.14 to 0.5 units by the year 2643 as the ocean absorbs more co2 , this phenomenon may cause extinction. As a direct result of increasing the amount of co2 in the atmosphere.Which may directly affect human societies that depend on marine ecosystems is great.
