Or at least they are established scientific facts (almost all, he flubbed a point or two)
Correct, but to increase the equilibrium storage, the partial pressure must be HIGHER, so oceans only moderate the increase in CO2, they cannot eliminate it.
Incorrect. The black body (actually gray since the earths albedo is about 0.3) is the determinant of the equilibrium temperature above the troposphere. The surface to the tropopause is determined by the equivalent calculation including the IR albedo (fairly dark since GHGs are good absorbers of Long Wave IR). Which is why the surface is about 33C warmer than the equilibrium to space.
True but immaterial to determining the stable temperature of the surface..
First, it's not correct that "CO2 disolves imto sea water because of the partial pressure of the C02."
Co2 is soluble in water. Dissolving CO2 in seawater increases the hydrogen ion (H+) concentration in the ocean, and thus decreases ocean pH. When CO2 dissolves, it reacts with water to form a balance of ionic and non-ionic chemical species: dissolved free carbon dioxide (CO2(aq)), carbonic acid, bicarbonate, and carbonate.
Second, it is not true that "Water vapor is also a more powerful greenhouse gas (by far) than any other."
There are three major groups or types of high High Global Warming Potential (GWP) gases: hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6). These compounds are the most potent greenhouse gases. In addition to having high global warming potentials, SF6 and PFCs have extremely long atmospheric lifetimes, resulting in their essentially irreversible accumulation in the atmosphere once emitted.
Nitrogen trifluoride, NF3 is 17,000 times more potent a greenhouse gas than carbon dioxide:
QED: as I posted before, his every sentence is WRONG.
