The climate models show that marine cloud brightening can affect
precipitation in both directions depending on when and where you spray.
We may not know where and when this should be but we can learn. Perhaps
we get blamed for not doing it.

Let's think about droughts.
Reducing the effect of rainfall on food production is an old idea.
It's called irrigation. But to make irrigation long term independent
from climate takes lots of capital and prodigious amounts of energy,
to desalinate sea water and pump it thousands of miles inland.
Or to take a Mississippi flood, clean out the silt and pump it into
the Ogallala Aquifer or over to the Colorado River (or both).
A really rich society could do that, especially one with oceans of
very low cost energy.
Should we put some numbers on what it would take?

PS BIo char from any source is darn good idea, even if we didn't need
to remove carbon.
PPS Andrew, it would help readability if you could preserve the
paragraph breaks.
