Well "Climate scientists say that the world must keep global temperatures from rising more than 1.5C (2.7F) to avoid some of the worst projected effects of climate change." So, like it or not, this is needed solutions, since other known alternative won't drop the temperature drastically or fast enough, its just a preventative measure to keep it under the threshold.
Eitherway the nature already done that anyway by spewing volcanic ash and sulfur just not in specific time and place that needed tweaking, in the end the real problem are the "Politic" and the bickering for their personal gain and fear being invaded or hijacked by this ecomanipulation resulting of it going nowhere, like they cannot form something like UN type for this decision.
