What this tells me is that there cannot be very high positive temperature feedback within the climate system if the “normal” or pre-industrial temperature record is totally flat.
Unless somebody has a better explanation, it seems likely that the IPCC needed to keep the 3.0°C ECS for political reasons and simply altered the various feedback parameters to suit.
Scientists have confirmed that a “stabilizing feedback” on 100,000-year timescales keeps global temperatures in check
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?
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...
