A planet warms until it radiates away exactly the sunlight it absorbs. Balancing absorbed power S(1−α)/4 against εσT⁴ gives the equilibrium temperature. An emissivity below 1 represents greenhouse gases trapping outgoing infrared, raising the surface temperature.

Governing equation
Reading this result: Dropping emissivity below 1 mimics greenhouse gases: they add 32 °C on top of the -19 °C bare-rock temperature.
