The Sea of Aral is well separated from the Caspian and only
around sea level, IIRC. You don't prevent much flooding by
refilling the Aral Sea. The locals would much prefer it, of
course. The Sovs considered this and backed off due to
cost and concerns about climatological effects on the Arctic.
If the greenhouse really takes hold the latter concern matters
far less and refilling the Aral looks better. It won't save Venice,

I don't get that. First, I doubt carbon will be the limiting material; I
anticipate it will continue to be nitrogen and phosphorus; if nanotech
requires only a tiny portion to be 3-bond atoms they continue to
be limiting. More to the point, it's way easier to use coal and oil
for carbon than to extract it from the atmosphere at 1%. Burning
fossil fuel makes the carbon far less available.
