That is another complete furphy VK3AUU. A typical attempt by the warmist scammers to come up with something bad they can hang on CO2. It can only very mildly reduce the alkalinity of the ocean, & only then during an ice age.

Any increase in temperature will cause the ocean to out gas CO2 making it even more alkaline.

Hasbeen. Well, at the moment the pH is getting lower because of the increase of the partial pressure of CO2 getting ahead of the temperature increase. I suspect that trend will continue into the indefinite future.

VK3AUU, if your suggesting that the increase in CO2 is causing the increase in temp and it's affecting the state of the oceans, you're wrong.
We are beginning to accept that the planet is going though a warming cycle, and because it is a CYCLE, it will eventually peak at a particular temp.
Now it is because the planet is warming, that CO2 is being released from the oceans, NOT the other way round.
Just thought I'd clear that up.

Altrav.
If the CO2 is being released from the oceans then how come the pH is getting lower.
David

VK3AUU, I don't know about Ph's but so as to not give any mis-information, what I now know, and is becoming more widespread is, that the planet is warming because of it's natural and normal life cycle, mostly affected by the sun.
It will slowly swing back to it's cold cycle in a few hundred year or so, and this has been happening since the planet was born.
Now where the lie, or con, comes into it is that if they had just said; the planet is warming, and left it at that there would have been no need for all this fuss over Fossil fuels and GW.
But no, for reasons known only to the scum who instigated this lie, they attached; because WE are burning fossil fuels.
NOT TRUE!
The CO2 is released from the oceans, because of the warming.
So warming first, CO2 after.
NOT the other way round!

Give this a look in, I have many more, if need be.

I must apologise to other members.
In my zeal to inject some light into the discussion I should have realised the futility of trying to teach a simple scientific principle to people who obviously have no appreciation of science, having learned what little they have from people with about the same minimal level of knowledge of the subjects.
