There's also a number of interesting applications in the evolution of Earth's atmosphere that branch off from the runaway greenhouse physics, for example how fast a magma - ocean covered early Earth ends up cooling — you can't lose heat to space of more than about 310 W / m2 or so for an Earth - sized planet with an efficient water vapor feedback, so it takes much longer for an atmosphere - cloaked Earth to cool off from impact events than a body just radiating at sigmaT ^ 4.

Water vapor, carbon dioxide, and a few other atmospheric gases act like the glass panes of a greenhouse, allowing sunlight in to warm the planet but preventing heat from escaping.

So as more CO2 gets pumped into the atmosphere the temperature rises, which causes more water to evaporate (as you accurately state), increasing the concentration of water vapor in the atmosphere — which heats the atmosphere even more, causing even more water vapor to enter the atmosphere.
