Wouldnt the water evaporate and block the weak sunlight...cooling the planet? Dont you really need enuf gravity to hold the gases in the atmosphere...for colonization...probably better to construct underground magnetically shielded environment...either way...a daunting problem...will earth last that long? Will our progeny die on a lifeless mars?
It’s science and there is a consensus on this thing.
Get with it, heretic...
