@mustapipa@scicomm.xyz Is that what happened on Venus? An arid planet with water less than 20-50% of water which could not recycle Carbon back thus unable to maintain an equilibrium.
If maximum amount of water was deposited on Earth during late heavy bombardment then wont that bombardment also delivery water to both Mars and Venus too? In equal measure?

@welkin7@mstdn.party That is indeed what the authors suggest. Venus is closer to the Sun and hotter, so there stable climate lasted perhaps for a billion years before runaway greenhouse effect took over. So its water inventory could even have been as high as on Earth, initially.
