The adverse impacts to marine organisms occur because most species that form calcium carbonate shell, CaCO3, require threshold concentrations of carbonate ions, CO3(2-) to be bioavailable in sea water. Carbonate ion alkalinity (acid neutralizing capacity, moles per liter) is being depleted as it buffers against significant pH change. Barely more than 0.1 pH unit decrease to about pH 8.2, but a SIGNIFICANT loss of carbonate ion alkalinity.

Yes it is.

Carbonate is not a chemical. Acetate is a salt. Citrate is not a chemical.

You cannot acidify an alkaline.
Carbon dioxide is not carbonic acid.
Carbonate is not a chemical.
Bicarbonate is not a chemical.

Plenty of clams, oyster, crabs, and other crustaceans.
Carbonate is not a chemical.
'Bioavailable' is not a word.
Alkalinity is not a chemical.
The pH of the oceans is unknown.
You cannot acidify an alkaline.
pH is not linear.

Circular argument fallacy (fundamentalism).

There is no such thing as a 'greenhouse gas'. No gas or vapor has the capability to warm the Earth.

WOW! This is awesome... maybe we'll get some kind of DEFINITION finally.

ITN happens to be right this time, pH is not linear.

So, what IS pH, if it is NOT linear? Is that a SECRET?

You don't know enough about pH to explain why it's not linear, or what non linear thing it IS.

Here's a clue. It is an exponential function, the base ten logarithm. "log"

Another clue, the math symbol "p" for NEGATIVE logarithm. p stands for -log

"H". Symbol for hydrogen, but understood to be (H+), the molar concentration (molarity, moles per liter) of hydrogen ION

SO, pH = -log(H+). pH is the negative logarithm of the hydrogen ion molarity.

DON'T BE AFRAID. Let this "buzzword" become your friend, and you will understand why a 12 M concentrated hydrochloric acid has pH = -1.08

You require that new members define their terms before they are allowed to discuss "climate change". DEFINE YOUR TERMS gets repeated a lot.
