As far as surface temperature is concerned — the Royal Society said that climate change is the result of ordered forcing and
internal climate
variability as a result of climate being an example of a
chaotic system.
Within the circular logic of natural
variability being
internal and
chaotic, yes.
They openly acknowledge the importance of the GHG - GHE in establishing the disequilibrium conditions that lead to a lapse rate and atmospheric heat transport in the first place, but then analyze that motion to argue that the overall feedbacks of this process are negative, not positive, something that actually explains the remarkable stability of our atmosphere in the face of
internal variability that (in a
chaotic system) could easily drive it to catastrophe.
I appreciate the time you have put into that but I don't think 1860 is far enough back to remove the obscuring effects of the lesser solar and oceanic cycles and
chaotic internal system
variability.
The interest of climate studies is to explore the boundaries between the stable and the
chaotic behaviors, and the expected effect of different external events (GHG, volcanoes, Sun,...) on these boundaries, as well as of the recent history (
internal variability).
Whereas each model demonstrates some sort of multidecadal
variability (which may or may not be of a reasonable amplitude or associated with the appropriate mechanisms), the ensemble averaging process filters out the simulated natural
internal variability since there is no temporal synchronization in the simulated
chaotic internal oscillations among the different ensemble members.
Forced
variability results from boundary conditions, such as sea - surface temperatures, and natural or
internal variability results from the
chaotic nature of dynamical systems1, 2.
