Nothing vague about it Webby. Fundamental conceptual problems leading to a grossly misleading formulation.
Still less do changes in state have anything to do with C02 – which is gaseous at any pressure and temperature to be found on Earth. The solubility curve is hyperbolic – so what? Why not just use the empirical curves and calculate the volume outgassed with temperature. You will find that CO2 is a multi-compartment problem – rather than one of a simple solubility in ocean water.
Again with the fundamental conceptual problems. Sometimes I wonder if you are hoaxing or simply delusional. Perhaps Occam’s razor suggests the latter.
