    Apologies ... I am not trying to scare you. Perhaps you would like to try to make up a new term for the lowering of pH ... Unbasification? Would that be better for you?

    Didn't you study politically correct chemistry? Jeeez! :wink:

    Let's call it the liberalization of reefs,... That will get them all on our side. :cool:

    Actually it does not matter what nitpicking you or Joanne-Icantfindmyownarsewithanatlas-nova want to do the fact remains the coral has bleached and died.

    Joanne is queen of straw man arguments if you had read the articles I posted they said nothing like what she asserts https://itsnotnova.wordpress.com

    They say no such thing. What they do say is

    You are creating a false argument.

    As usual all you have are personal attacks and insults. Obviously you did not read the link (again a closed mind is a terrible waste). The short tutorial was written by: Professor Brice Bosnich

    And again what has happened to the coral reefs has nothing to do with global warming.

    One of the bad assumptions is the amount of CO2 in the atmosphere in the year 2100. They also disregard the buffering capability of ocean water and the variability of pH daily which can range up to 0.5 pH units on a daily basis. There is also no consideration of homeostasis in which organisms with CaCO3 based shells and skeletons maintain internal chemistries including the systems which produce the exoskeletons independent of small changes in their environments.

    They are claiming (but not quantifying) that the lower amount of carbonate ion (CO3) in the ocean water will result in the destruction of those organisms. There is no evidence that this will happen even though the daily variation of pH in which these organisms exist cover and exceeds the 7.8 pH concentration that they claim to be a tipping point.

    I feel your pain. :smile:

    The correct way in which chemists describe the process of changing or lowering pH is neutralization. When performing a titration acid or base is added to a solution to produce a neutral solution as measured by pH meter or litmus paper. Chemists do not talk about acidifying a basic solution or base-ifying an acid solution. The term acidification has been created by alarmists to create alarm - scare people who are not well informed about water chemistry. The impression desired and created by alarmists is that the ocean is turning to acid which will disolve everything.

    You almost got it ... the definition you provide is correct, but not complete.

    Acidification also means: A change in natural chemical balance caused by an increase in the concentration of acidic elements. To think of a large volume of liquid in the same way you think of the beaker in your intro to chemistry class is largely incorrect.

    As CO2 dissolves in the ocean it changes sea water chemistry. CO2 reacts with water molecules (H2O) and forms the weak acid H2CO3 (carbonic acid). Most of this acid dissociates into hydrogen ions (H+) and bicarbonate ions (HCO3-). The increase in H+ ions reduces pH (measure of acidity) and the oceans acidify, that is they become more acidic or rather less alkaline since although the ocean is acidifying, its pH is still greater than 7 (that of water with a neutral pH).

    To apply the term 'neutralization' to this process would be wrong.

    The term "acidification" is used to cause alarm. Google the term "acidification" - all the links have to do with ocean acidification. The term was never used in chemistry to describe a process in which the pH of a solution was lowered.

    Again this is a clear strawman argument. Unable to attack the real science a false argument is presented with vague allusions as to where the points originated. The false argument is then attached which is easy to do since it was bull(*)(*)(*)(*) in the first place and has no real relationship with actual research done anywhere

    The false argument is that the coral reefs are being destroyed due to global warming.

    OMG!!! Everyone in North Queensland must be seeing things then!!! What alternate explanation due you have because JCU would pay for you to come over and lecture if you could find a solution

    Look upthread for the information you are seeking. There is no connection between global warming and the conditions of Australian coral reefs.

    Overfishing in Senegal leaves industry in crisis...

    Overfishing Leaves an Industry in Crisis in Senegal
    June 07, 2017 — It was almost sunset as fishermen guided their boats back onto the beach at Joal, Senegal, after a long day at sea. At first glance, it looks as though they'd collected a good day's haul, but their nets were full of small sardinella, known locally as yaabooy.

    OP

    50% gone? I reckon that's it then - back in the days when I had a marine aquarium, keeping the corals healthy was a total nightmare.

    That ridiculous premise has been refuted many times.

    That's pretty simple when you consider the amount of water in your aquarium and the amount of water in the ocean. They poison themselves with their own waste. Not to mention temperature fluctuation. If everything isn't kept just so they die.

    Oh I was very diligent on the maintenance aspect almost to the point of neurotic, but the trouble is that a marine aquarium owner can execute the regime, find everything is spot-on, then half an hour afterwards an imbalance or some other adverse event can occur which negates that check and hypoxia problems start kicking off. That's really why I dismantled it all - despite doing all the right things **** still happened, and it demoralised me into calling it a day.

    Thank you for the link. I was not aware of the impact of climate change on coral, and the surrounding ecosystems. Just one more reason the US should not have backed out of the Paris accord.

    I visited and snorkeled the Great Barrier Reef over 20 years ago. It was absolutely beautiful!
