There was some comment linked to someone else's claim that acidity hasn't increased. The context of that is long gone, glad you accept that the ocean has become more acidic due to the increase in CO2.
We're now at the point where you claim the increase in CO2 from the 280ppm of the 1880's is entirely natural and just a coincidence that this happened after we emitted 2,575 gigatonnes. This is hard core denial of reality.
