«Radiative forcing [RF] can be related through a linear relationship to the global mean equilibrium temperature change at the surface (delta Ts): delta Ts = lambda * RF, where lambda is the climate sensitivity parameter (e.g., Ramaswamy et al., 2001). (realclimate.org)

climate sensitivity = equilibrium temperature change for doubled atmospheric CO2 concentration (realclimate.org)
