COVID Is Transmitted Through Aerosols. We Need to Adapt | Time
The ability of stratospheric aerosols to create a global dimming effect has made them a possible candidate for use in solar radiation management climate engineering projects  to limit the effect and impact of climate change due to rising levels of greenhouse gases. One study calculated the impact of injecting sulfate particles, or aerosols , every one to four years into the stratosphere in amounts equal to those lofted by the volcanic eruption of Mount Pinatubo in ,  but did not address the many technical and political challenges involved in potential solar radiation management SRM efforts. It has been suggested that the direct delivery of precursors could be achieved using sulfide gases such as dimethyl sulfide , sulfur dioxide SO 2 , carbonyl sulfide , or hydrogen sulfide H 2 S. According to estimates, "one kilogram of well placed sulfur in the stratosphere would roughly offset the warming effect of several hundred thousand kilograms of carbon dioxide. The arguments in favour of this approach in comparison to other possible means of solar radiation management are:. It is uncertain how effective any solar radiation management technique would be, due to the difficulties modeling their impacts and the complex nature of the global climate system. Certain efficacy issues are specific to stratospheric aerosols.
