MacMartin, Douglas G.; Ricke, Katharine L.; Keith, David W. (2018): Solar geoengineering as part of an overall strategy for meeting the 1.5°C Paris target. In Phil. Trans. R. Soc. A 376 (2119), p. 20160454. DOI: 10.1098/rsta.2016.0454.
"We first provide a physical science review of current research, research trends and some of the key gaps in knowledge that would need to be addressed to support informed decisions. Next, since few climate model simulations have considered these limited-deployment scenarios, we synthesize prior results to assess the projected response if solar geoengineering were used to limit global mean temperature to 1.5°C above preindustrial in an overshoot scenario that would otherwise peak near 3°C. While there are some important differences, the resulting climate is closer in many respects to a climate where the 1.5°C target is achieved through mitigation alone than either is to the 3◦C climate with no geoengineering. This holds for both regional temperature and precipitation changes; indeed, there are no regions where a majority of models project that this moderate level of geoengineering would produce a statistically significant shift in precipitation further away from preindustrial levels."
