A maximum entropy climate – Earth in transient energy equilibrium

Terra et Aqua

I think I’ve never heard so loud
The quiet message in a cloud.

Hear it now, what were the odds?
The raucous laughter of the Gods

The energy balance of the planet is stark where the climate system meets space.  The change in heat energy content of the planet – and the work done in melting ice or vaporizing water – is approximately equal to energy in less energy out.  There are minor contributions with heat from inside the planet and the heat of combustion of fossil fuels – for instance – that make it approximate but still precise enough to use.   Energy imbalances – the difference between energy in and energy out – result in planetary  warming or cooling – and Earth’s strong exponential temperature feedback response tends to drive the planet to a transient energy equilibrium.  Maximum entropy is when there is an energy equilibrium at…
