@martinvermeer @yokofakun I don’t see your claim in the link, but it sounds like you’re saying that the concentrations of CO₂ in the atmosphere and ocean are far out of equilibrium, and would rapidly approach equilibrium by CO₂ moving into the ocean. If that rate hasn’t been keeping up with emissions already I don’t see why it would catch up quickly. But I suppose the idea does illustrate that I’d have to say more to justify treating that reference as a floor
