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.
