There is a lot of talk about the need for multidisciplinary approach to Climate. To me that is an obvious requirement, starting with just the definition of what the "Climate System" entails. Playing with the opposing forces and multi-disc models, I am finding there are quite a few energy boundary layers that cannot be dismissed as negligible.
To me, the Earth system begins with the dynamic energy in the core itself. The internal dynamo generates heat, a magnetic field and as a fluid, has some impact rotation/tilt of the planet itself.
Between the core are thermal/radiant boundaries, the 4C sea water density boundary, the surface/atmosphere boundary, the Atmospheric boundary layer which consider the latent boundary to be a part, the thermal/radiant boundary layer, the tropopause boundary and so on until the thermal/non-thermal radiant boundary layer and space, in just the vertical. This should be the system envelope.
With opposing forces, the impact of any of these layers can be twice their singular value. For example, Arrhenius' greenhouse relationship appears to be an ideal relationship that would produce twice the impact. Based on the climatic conditions at the time of his paper and the region he lived, that is what he would have discovered attempting to explain the glacial/interglacial climate transitions, the ideal relationship. In the real world, only half of his expectations are realized globally, with regions near ideal conditions approaching his expectations.
This is one of the largest mistakes being made in climate science, comparing the real world to a ideal world. People lose sight of the subtle expecting the exceptional.
