Stratospheric aerosol injection (SAI) 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 winter . [ 1 ]
Schematic with five proposed methods for solar radiation modification technologies. Solar radiation modification (SRM) (or solar radiation management or solar geoengineering), are large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.
Climate engineering (or geoengineering, climate intervention [1]) is the intentional large-scale alteration of the planetary environment to counteract anthropogenic climate change. [ 2 ] [ 3 ] The term has been used as an umbrella term for both carbon dioxide removal and solar radiation modification when applied at a planetary scale.
A weather balloon is launched as part of the National Oceanic and Atmospheric Administration's Balloon Baseline Stratospheric Aerosol Profiles project, which is taking aerosol measurements to ...
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.
This is a proposed solar geoengineering intervention which aims to counteract global warming through intentional releases of reflective aerosols. [18] Stratospheric aerosol injection could be very effective at stopping or reversing warming but it would also have substantial effects on the global water cycle, regional weather, and ecosystems ...
Zevenhoven et al. state that "instead of stratospheric aerosol injection (SAI), cloud brightening or a large number of mirrors in the sky (“sunshade geoengineering”) to block out or reflect incoming (short-wave, SW) solar irradiation, long-wavelength (LW) thermal radiation can be selectively emitted and transferred through the atmosphere ...
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 ...
