Maximum entropy production, cloud feedback and climate change

Paltridge, Garth; Cuntz, Matthias Oskar; Farquhar, Graham


A steady-state energy-balance climate model based on a global constraint of maximum entropy production is used to examine cloud feedback and the response of surface temperature T to doubled atmospheric CO2. The constraint ensures that change in zonal cloud amount øo necessarily involves change in the convergence KX of meridional energy flow. Without other feedbacks, the changes in øo, KX and T range from about 2%, 2 Wm-2 and 1.5 K respectively at the equator to -2%, -2 WM-2 and 0.5 K at the...[Show more]
