Are Climate Feedbacks Strongly Non-Linear?

Is it possible that the Earth’s system is strongly buffered with strong positive ice and dust feedbacks prevailing at colder temperatures, and strong negative convection/evaporation feedbacks prevailing in warmer times?

An Electronic Analog to Climate Feedback

Here we simulate a “test rig” for illustrating the difference between Christopher Monckton’s approach to projecting equilibrium climate sensitivity (“ECS”) and what he says climatology’s approach is. (ECS is the…
