The stratospheric injection of sulfate aerosols would cause the Vienna Convention for the Protection of the Ozone Layer to be applicable due to their possible deleterious effects on stratospheric ozone. That treaty generally obligates its Parties to enact policies to control activities which "have or are likely to have adverse effects resulting ...
There are some proponents who argue that unlike stratospheric aerosol injection, space-based approaches are advantageous because they do not interfere directly with the biosphere and ecosystems. [48] However, space-based approaches would cost about 1000 times more than their terrestrial alternatives. [49]
Along with stratospheric aerosol injection, it is one of the two solar radiation management methods that may most feasibly have a substantial climate impact. [1] The intention is that increasing the Earth's albedo, in combination with greenhouse gas emissions reduction, would reduce climate change and its risks to people and the environment. If ...
Giant sun shades, 40-foot-tall air filters, stratospheric sulfur injections: Here are some of the wild and wondrous ways we might save the planet. New scientific interventions are here to fight ...
Enhancing the solar reflectance and thermal emissivity of Earth in the atmospheric window through passive daytime radiative cooling has been proposed as an alternative or "third approach" to climate engineering [26] [50] that is "less intrusive" and more predictable or reversible than stratospheric aerosol injection. [51
The term refers to activities like stratospheric aerosol injections, an untested theory that the planet could be cooled by spraying particles into the stratosphere from high-altitude aircraft ...

One main impact of volcanoes is the injection of sulfur-bearing gases into the stratosphere, which oxidize to form sulfate aerosols. Stratospheric sulfur aerosols spread around the globe by the atmospheric circulation, producing surface cooling by scattering solar radiation back to space.
