Two features are being conflated, and I don't know how much expert 
work has been done on this (other than knowing that yes, stabilized 
solarettes could be put there). My wife the hands-on and 
theoretically-informed practical permaculture farmer is aghast at the 
handwaving involved. You cool the planet by deleting some significant 
proportion of current insolation (using shades or aerosols or 
whatever), and what happens to the crops and grasses and livestock 
that have evolved or been bred to roughly our recent annual round? 
This is a vast multidimensional question.
