Well, the gravity on Mars is only 1/3 of Earths, and the canopy would be light anyway so I don't see it as that much of a problem.

quote: crash a few more comets into Mars.

If the Earth was running out of water, would crashing comets onto it be an acceptable solution? Comets tend to destroy things...

But I think that any atmosphere would persist for long enough anyway.

Sure; crash into Pacific. On Mars, crash into the highlands (not likely to ever be inhabited due to low pressure).

p.s. I'm joking about the US "owning" the oceans.

I think I'd rather try reducing the Venusian atmosphere to tolerable levels. Given what we're learning about bio-engineering and the ability of natural microbes to deal with searing heat and crushing pressure, I doubt a workable solution is very far off.

How are you going to speed the planets rotation up?

Currently, Venus' 'days' last for 234 Earth days. Its years are shorter than that!

What would we seriously name our Martian cities? What would Europeans call them? Or Americans?

Only problem I have with open range oceans is environmental problems (read overfishing). Even with a 200 km enforcement barrier we've still got the Japanese and Spanish squatting at 201 km and destroying what's left of the cod stocks while we prevent our own fishermen from earning a living to improve the situation.

IIRC, a moderately dense atmosphere could be established quickly on Mars by asteroid bombardment of the polar regions. The composition of the asteroids doesn't really matter, the polar CO2 would do it. It would eventually either be lost to space or freeze out at the poles again, but not for millennia.

And there are big advantages to giving Mars a decent atmosphere even if it isn't breathable. You don't need to build pressure domes (just reasonably airtight tents), and you could step outside with a warm coat and an oxygen mask rather than a hermetically-sealed spacesuit.

Why are we even talking about terraforming Mars? To do that would require a vast political transformation on earth. Environmentalists would go bezerk, wouldn't they?

Yes. This is a classic Adam Smith "commons grazing" problem.

The dynamic also extends to navigability of straits, limits of international water, etc. As a (****...the) naval power, we prefer having very free oceans. Most of the rest of the world, would like to extend their territory into the water by law.

Totally impractical. Plus there is the issue of damage to property...not just damage to people.

But anyway, why would we ever need to put comets in the ocean? There is plenty of water on earth. (And if you dump that ice in the Pacific...you mix it with seawater and still have to desalinate it...not very convenient.)

I was mainly being silly, but if Earth was ever actually running short of water then I don't see us not using available resources and sacrificing the few for the many...

Anyhoo, break up comets prior to impact (10 meter chunks) and they'll break up on contact so no problem...
