A personal view : Solar costs are falling precipitously. And this makes geoengineering more urgent, not less. To quote from the article linked below
"Citigroup said solar already competes in the growing regions of the world on "pure economics" without subsidies. It has reached grid parity with residential electricity prices in Germany, Italy, Spain, Portugal, Australia and the US southwest. Japan will cross this year, Korea in 2018. It forecast that even Britain will achieve grid parity by 2020, a remarkable thought for this wet isle at 51 or 52 degrees latitude." http://www.telegraph.co.uk/finance/comment/ambroseevans_pritchard/11046842/Oil-industry-on-borrowed-time-as-switch-to-gas-and-solar-accelerates.html Solar power is not only cheap, it's available everywhere (if not everywhen). After years of fruitless negotiations, we're about to see technology hand decarbonisation to us on a plate. When the transition comes, it will be frighteningly fast. I suggest that we'll see large scale grid decarbonisation within a decade of the crossover, and this will take vehicles with it. Only winter heat and air travel will be stubbornly resistant, as EV batteries buffer demand through the day. Herein lies a problem. The tropospheric aerosols are going to go away, and fast. They're shielding us from a substantial fraction of present warming. We have until around 2030 to decide what to do about this. Nothing anyone can say or do will defer this day of reckoning. We'll need to be deployed on adapted by then, and I don't think adaptation will happen.
