    The problem with the up-welling water is that it is not saturated with Calcium. Or, to be technical, it has a negative Langelier Saturation index. Changing the LSI to +1 with the same pH will help cure the problem.

    Acidification will starve the oceans of O2 because it effects phytoplankton. We've already lost 40%of phytoplankton overall mass since the 60s. Phytoplankton provides 50%of the O2 you breath.

    Here are 6 recent peer reviewed papers that disagree with the dooms day of a less alkaline ocean. Maybe make a part II and address these counter arguments.

      Did you read the reviews you presented? They aren't denying ocean acidification.

    Given the pollution halogenated vinyl halogenated carbon and nuclear radiation as well as the breakdown of atmosphere products of basic salts. We would expect that sulphate and ammonium sulphate nitrate and alkaline water is the ocean pH.

    Algea is food for plankton? Right, also how about those things that eat algea off rocks also?

    Still waiting for the breakdown in the food web.

    I wonder if the Pteropod experiment is being done correctly. Did you just reduce the pH of the water, or did you make other adjustments. Try adding an excess of Sodium Bicarbonate or Calcium Carbonate power and then adjusting the pH and see if you have the same results. Make certain that there is still an excess of the Sodium Bicarbonate or Calcium Carbonate power over what will dissolve after the pH is adjusted. The ocean at shallow depths is always saturated with Calcium Carbonate/Bicarbonate. If you understand the Langelier Saturation index you should know that it is the lack of this saturation, NOT the pH that makes water corrosive to Calcium compounds.

      not sure about that one.

    Wait, you're saying that lower water temps hold more CO2 and that the oceans are warming therefore holding less CO2. Which is it?

  • @blaineshower6426

    Co2 was at 7000 ppm when shellfish and coral and marine life exploded during the Cambrian period. The oceans have 45 times the concentration of Co2 than the atmosphere... once again we have activism and alarmism and junk science

    It is impossible for an increase in atmospheric CO2 to acidify the oceans.

    • @hankstevens7628

      Actually, that is exactly how it happens. Adding CO2 is like creating carbonic acid.

      I think ocean acidification is such an esoteric topic, even now, that it is unlikely for average people to take an interest in it. Even more so, research it and come with counter-arguments(or try to). Now i have listed through the comment section of 3 ted talks on OA and there are a lot of opinionated people against the science of OA.
      The point i am driving at, is that in my subjective opinion, these are paid trolls that try to delegitimize the science surrounding this topic.
      And when special interest put this much effort in such an obscure topic.... you know it's bad.

      Graham Lyons That's not true.

      How did Lyons comment get two likes? Moe, Larry, and Graham (Curly) Lyons?
