In the case of a failure of the surface to warm due to a La Nina - like process, the OLR reduction (and hence the energy gain) will be lessened by the reduction in water vapor and other feedback moieties, but it will still be greater than occurs with a warmed surface.

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differential heating.
