[en] We have compared sensitivities of four different radiative-convective climate models. Although surface temperature sensitivities with respect to changes in solar constant and atmospheric, CO₂ concentration are almost the same in all models, sensitivity with respect to some other climate variables varies up to a factor of 2. We have found that the surface temperature sensitivity with respect to changes of the lapse rate is high in all models, and we emphasize the importance of a lapse rate--surface temperature feedback
