In this case the CO2 concentration is instantaneously quadrupled and kept constant for 150 years of simulation, and both equilibrium climate sensitivity and RF are diagnosed from a linear fit of perturbations in global mean surface temperature to the instantaneous radiative imbalance at the TOA.

Notice that in order for this to hold at some level, the gradient in σ * T ^ 4 has to be constant out to some large optical depth up and down from that level, to «insulate» the level from the perturbation radiative fluxes from perturbations to the pattern.

However, because global warming is always of one sign, a much bigger impact is from the cumulative effects of these radiative perturbations on the climate.

Numerous attempts to confirm these correlations based on different climate models have shown that it is only possible if either the applied perturbations of direct solar radiative forcing are large (consistent with a direct solar radiative forcing from the present to Maunder minimum ΔFP − M ~ 0.6 − 0.8 W / m2) or if the amplification of a weak direct solar forcing is substantial.

Equation -LCB- 6.1 -RCB- is defined for the transition of the surface - troposphere system from one equilibrium state to another in response to an externally imposed radiative perturbation.
