Is this another technocratic solution?
Have I been hiding under a rock or something - I read this term for the first time today. I am not sure we are grown up enough for this? Where is the public discourse here? Who will get the contract and what parts of the world win and which will loose? And who decides? Yikes!
Geoengineering is the deliberate modification of Earth’s environment on a large scale "to suit human needs and promote habitability".  Others define it more narrowly as focusing only on the mineralogy and hydrology of the Earth. The term geoengineering is distinct from accidental anthropogenic climate change. (wikipedia)
I came across the term here. It sounds like scientific rationalizations at a massive scale, is it the offshoot of that engineering god complex taken that one step larger than ever! I have to learn about this a bit more. Wholly tomolli!
