On closer examination, however, this disagreement appears to be the recorded part of a
sometimes heated dialogue between experts in a rapidly developing field as they try out a new way of parameterizing some part of the problem (such as the
effects of moist convection), or as they parameterize a previously specified quantity (such as
snow cover).
The ratio in which they cooperate on the final
effect — relatively narrow range of survivable temperatures — is another question; it is for sure, that the most abundant IR active gas likes to create clouds, which effectively cool the surface, then it rains down and again effectively cools the surface and
sometimes gets frozen to
snow, which reflects sunlight and again effectively cools the surface.
