In the GCM, if a layer is statically unstable relative to a specified convective temperature lapse rate, a convection scheme relaxes temperatures in that layer toward an enthalpy - conserving profile with the convective lapse rate. (climate-dynamics.org)
This is somewhat compensated by the negative temperature lapse rate feedback that weakens the greenhouse effect. (climate-dynamics.org)
