Ok, after researching this, It turns out the Caspian Sea has risen some
2.25 meters since 1978 (it had previously dropped 1.77 meters between
1933 and 1978) and is risking some coastal damage, however, its surface
is still 28 meters below sea level. With a surface area of 373,000
square km, and another 100,000 sq km of adjacent land below sea level,
this results in 1.15 x 10^13 cubic meters of volume below sea level
available for flooding. This flooding should provide 10 cm of worldwide
sea level lowering. If we wanted to we could pump an additional 200
meters of sea water up to the Caspian Sea from the Black Sea, which
would cover about 600,000 sq km and lower oceanic sea levels by at least
a meter.

Now, if we covered the area in a big space blanket, how quickly could we
freeze that water into ice for storage?
