Global thermostat — too good to be true?

This is a stunning piece of work. Have a look. I hope to say more later.

Who knew that the sun has increased its output by 30% since the far geological past, and yet the earth did not heat up as it did so? It’s called the Faint Early Sun Paradox and it was always a bit tricky to explain, until now…

The stability of the earth’s temperature over time has been a long-standing climatological puzzle. The globe has maintained a temperature of ± ~ 3% (including ice ages) for at least the last half a billion years during which we can estimate the temperature. During the Holocene, temperatures have not varied by ±1%. And during the ice ages, the temperature was generally similarly stable as well.

Willis Eschenbach has proposed a thermostat for the control of global temperature. His clear exposition of it has just appeared on Watts Up With That. Will it survive scrutiny? Read it through, have a think, let us know.
