It seems that there is a confusion of cause and effect here. The
presumed
cause in the articles you cite is human activity increasing the
concentration of CO2 in the atmosphere. CO2 concentration is on the
order
of 300 ppm. My point was that in order to lower the pH of a volume of
liquid, a specific volume of acidic substance must be added. Even the
most
hysterical of the GW believers don't place human impact at more than
several ppm. If one were to compute the volume of water in the ocean,
the question is how much volume of acidic substance must be added to
that
liquid volume in order to change the pH even 0.1?

How do you determine this? Define your experiment for me. I think you
will begin to see the complexity. The ocean is not just water.
There's lots of stuff in it.


Why do I have to define the experiment?

Because you proposed determining "how much volume of acidic substance must
be added to that liquid volume in order to change the pH even 0.1"

This type of experiment can't be done in a jar. Which is why I was
interested in how you would go about computing "the volume of acidic
substance" needed.


The oceans contain a specific volume of water, that volume of water
possesses a certain pH level. Holding all other things constant (as the GW
adherents appear to be doing), then it will take a certain volume of acidic
substance to lower the pH of that volume of ocean water.

I'm not trying to prove that
humans are changing the ocean pH. I'm merely pointing out that there is
a heck of a lot of volume of water, that were everything else to remain
constant would require huge volumes to change the pH.

Well guess what? The pH is changing.
So what was the point to your "sanity check"?

The point of my sanity check was to establish cause. The data says pH is
changing, that is the data, and if true, is a fact. The GW zealots scream
that it is man-made increases in CO2 that is causing this change. That is
speculation, theory, and conjecture. My challenge to the luddites (who are
ultimately trying to reduce human industrial activity) is how much CO2
would have to be produced by humans to be able to produce sufficient acidic
substances to make a measureable change in ocean pH? That provides a sanity
check vis a vis whether it is even possible for humans to have any impact
upon ocean pH. Shoot, I could posit the theory that Madonna peeing the
shower is responsible for the change in ocean pH -- wouldn't make it so,
but if I screamed loud enough and had a fax machine with an impressive
letterhead I could probably get Reuters or AP to pick up on it.
