1 big pro and 4 cons of solar geoengineering - Inverse

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 Web23 Jan 2024 · The Stratospheric Aerosol Geoengineering Large Ensemble project is a 20-member ensemble of stratospheric sulfate aerosol geoengineering simulations between 2024-2099 and a 20-member ensemble of control simulations over a reference period between 2010-2030 using the NCAR Community Earth System Model with the Whole … Web30 Jun 2011 · NASA's Stratospheric Aerosol and Gas Experiment (SAGE II) monitored them from 1984 to 2005, and the joint NASA/CNES Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) has been … grain capacityとは
