The World Academy of Sciences: Trieste Next: Hacking the climate?

"Spraying aerosol particles into the atmosphere could block a portion of the sun's warming energy and help check global warming. But potential dangers of radiation management still need to be explored, scientists said at TWAS's Trieste Next roundtable."

Clean Technica: Scientists Prescribe A Healthy Dose Of Sulphate Particles To Promote Global Cooling On The Cheap

"June 16, 1883. The island of Krakatoa in the Java Straits disappears in a volcanic eruption so powerful it blots out the sun in many places around the world. Millions of tons of hydrogen sulfide gas are hurled high into the Earth’s atmosphere, where they remain for years. Tracking the ash clouds from Krakatoa alerts the scientific community for the first time to the existence of the jet streams."

Interesting Engineering: Anti-Global Warming Atmospheric Spraying Possible but Too Costly, Finds Study

"Researchers find that a program to fight climate change by injecting aerosols into the atmosphere from high-altitude aircraft would be possible, but unreasonably costly and unlikely to remain secret."

The Nation: Scientists propose new way to tackle climate change

"LOS ANGELES-Scientists have proposed a new way to tackle climate change by spraying sun-dimming chemicals into the Earth's atmosphere, according to a study published on other day. Scientists at Harvard and Yale universities have proposed using a technique known as Stratospheric Aerosol Injection (SAI), which they believe could cut the rate of global warming by half, according to a paper published in the journal Environmental Research Letters."

Smith, W.; et al. (2018): Stratospheric aerosol injection tactics and costs in the first 15 years of deployment

Smith, W.; Wagner, G. (2018): Stratospheric aerosol injection tactics and costs in the first 15 years of deployment. In: Environ. Res. Lett. 13 (12), S. 124001. DOI: 10.1088/1748-9326/aae98d.

"We review the capabilities and costs of various lofting methods intended to deliver sulfates into the lower stratosphere. We lay out a future solar geoengineering deployment scenario of halving the increase in anthropogenic radiative forcing beginning 15 years hence, by deploying material to altitudes as high as ~20 km. After surveying an exhaustive list of potential deployment techniques, we settle upon an aircraft-based delivery system. Unlike the one prior comprehensive study on the topic (McClellan et al 2012 Environ. Res. Lett. 7 034019), we conclude that no existing aircraft design—even with extensive modifications—can reasonably fulfill this mission."
