The atmospheric "feedback processes described" are those implemented into UN/IPCC climate models. They constitute speculative and inadequate mechanisms at best, presumptive at worst, by which the atmosphere might respond to changes in radiative heat balance.

Would you mind listing the atmospheric feedback processes you are describing here?

Primarily that 2-2.5K surface warming predicated on those feedback processes described by Ramanthan (Journal of Geophysical Review, vol. 84, pp. 4949-4958) , Where magnitude and indeed even the sign of the feedback hypothesized to be derived from moisture and cloud cover fail to be realized in any atmospheric measurements. Processes which presumptively attributed to CO2 radiative warming in GCMs must in reality respond to any perturbation to the climate equally.

The problem is measurement does not support anything near the presumed magnitude or even sign of feedback processes hypothesized and implemented into the fabric of the GCMs. And certainly not to the tune of the 10x feedback that is required to make the GCMs work in magnifying the 0.2oK direct radiative heating attributable to doubling of CO2 concentration into a 2-3oK increase in global atmospheric temperature.
