This is true until either the planet hits boiling (water stops being a vapor and becomes a gas), or until it runs out of oceans. Thus, it can't start runaway greenhouse on its own. The articles I read suggest CO2 outgassing from vulcanism, if Venus used to be Earth-like. | |

I realize at some point it had to lose most of the water, but what I meant is that water itself was the originator of the runaway greenhouse effect on Venus. | |

All of the water on Venus would hardly fill an olympic sized swimming pool. It was done outgassing a long time ago. The entire atmosphere blows around the planet once every four Earth days, but the surface itself takes 243 days to go the distance. | |
