Given that any previous water in the atmosphere has mostly escaped over time, the dome seems like a better bet.

- ryanmercer 8y agoMars lost its atmosphere on a geological time scale. You just need to raise the average temperature 5C to create a runaway greenhouse effect (and that gas release from the polar regions would far outpace the solar winds stripping atmosphere away and once it leveled off would take millions of years to get back to the state it is in now). The very thin atmosphere it has now, will take another 2 billion years or so to be stripped away entirely.
