You're both forgetting that Martian gravity is but 1/3 that of Earth.1. Fair enough.
Please explain, then, CO2's role in regulating atmospheric temperature...2. The atmosphere does not prevent the radiation by and large, that would be the magnetosphere.
It's no wonder you don't 'buy' climate change. You clearly don't even understand the basic mechanisms.
Not even hard math can anticipate the behavior of a spontaneously generated atmosphere on a relatively small, low-G, tectonically dormant planet, orbiting at ~1.5 AU's, with two moons and a barren landscape. Bring back a hydrologic cycle under these conditions, and all theory goes out the window.3. I think that's one of the claims that would need hard mathematics, not gut instincts. C02 isn't terribly heavier than O2.
S-waves, the most damaging manifestations of earthquake E release, travel along surfaces. Exactly like waves traveling across the surface of a lake:We could build significant structures under ground which would shield from radiation and hold a more manageable sustainable atmosphere. There's no evidence that there is still tectonics going on that I know of, so we can probably assume it will be safe to build submartian structures (it's going to be painful replacing "terranean" with "martian".)
According to some theories, Mars should have large untapped hydrocarbon reserves for the settlers. Apparently they aren't limited to the Carboniferous and biology, they'll form from carbon deposits in the mantle.
The safest place to be during an earthquake is underground.
And carbon deposits in the mantle...good luck with that. We should just send Dr Evil ahead to establish the base!
