Again, this is something that can niether be proven nor disproven until we try. And again I disagree.Originally posted by monolith94
None of this is feasible within our life times of course. And it'll be many lifetimes before such a plan is economically viable.
Venus' atmosphere is something like 400 times as dense as Earth's. Not even Earth can become another Venus unless we really, really try. Hell, Earth has been much hotter than it is currently or feared to become so there's no real concern here. Mars, having a much thinner atmosphere, is at about 0% risk of turning into Venus. It's simply too far away from Sol to receive much heat, its gravity isn't strong enough to hold that dense an atmosphere, and there's the lack of a decent magnetosphere to protect from solar wind blowing away said atmosphere.My question is, if you start a greenhouse effect, how would you stop it? We wouldn't want Mars to become another Venus.
