That's actually the wrong question.  Given that we want to keep the earth 
close to the current temperature or even cool it a bit, what method is the 
least disruptive?  It might turn out that a mess of sunshades in the 
earth-sun L1 location are the best (least clostly) way to go.

Although we don't now worry about too *little* CO2, if there was really 
widespread use of CO2 to grow massive engineering structures out of diamond 
*that* could become a problem.
