WebStratospheric aerosol injection, which is a very promising climate engineering approach, involves the release of reflective particles such as sulfate into the stratosphere to reflect sunlight into space (Figure 2). It was first proposed by Mikhail Ivanovich Budyko in 1974 (Rasch et al., 2008/Keith, 2000). ... Web26 May 2024 · We propose a method for stratospheric aerosol climate modification that uses a solid aerosol composed of alkaline metal salts that will convert hydrogen halides and nitric and sulfuric acids into stable salts to enable stratospheric geoengineering while reducing or reversing ozone depletion.

Stratospheric aerosol injection is a proposed method of solar geoengineering (or solar radiation modification) to reduce global warming. This would introduce aerosols into the stratosphere to create a cooling effect via global dimming and increased albedo, which occurs naturally from volcanic eruptions. … See more Materials Various forms of sulfur were proposed as the injected substance, as this is in part how volcanic eruptions cool the planet. Precursor gases such as sulfur dioxide and hydrogen sulfide have … See more Primary aerosol formation, also known as homogeneous aerosol formation, results when gaseous SO 2 combines with oxygen and water to form aqueous sulfuric acid (H2SO4). This acidic … See more It is uncertain how effective any solar geoengineering technique would be, due to the difficulties modeling their impacts and the complex nature of the global climate system. … See more Almost all work to date on stratospheric sulfate injection has been limited to modeling and laboratory work. In 2009, a Russian team tested aerosol formation in the lower … See more The advantages of this approach in comparison to other possible means of solar geoengineering are: • Mimics a natural process: Stratospheric sulfur aerosols are … See more Early studies suggest that stratospheric aerosol injection might have a relatively low direct cost. The annual cost of delivering 5 million … See more Solar geoengineering in general poses various problems and risks. However, certain problems are specific to or more pronounced with stratospheric sulfide injection. • Ozone depletion: a potential side effect of sulfur aerosols; and … See more WebStratospheric aerosols are an important component of Earth's albedo, and therefore energy balance, and provide surface area for heterogeneous chemistry, which can lead to … high rise condos columbus ohio
