@article{Lucarini2010ASM, title={A statistical mechanical approach for the computation of the climatic response to general forcings}, author={Valerio Lucarini and Stefania Sarno}, journal={Nonlinear Processes in Geophysics}, year={2010}, volume={18}, pages={7-28} }

Abstract. The climate belongs to the class of non-equilibrium forced and dissipative systems, for which most results of quasi-equilibrium statistical mechanics, including the fluctuation-dissipation theorem, do not apply. In this paper we show for the first time how the Ruelle linear response theory, developed for studying rigorously the impact of perturbations on general observables of non-equilibrium statistical mechanical systems, can be applied with great success to analyze the climatic…
