Just as large volcanoes cool the planet by ejecting massive amounts of small particles into the stratosphere, one sunshade geoengineering proposal would involve using high - flying airplanes to release small particles in the stratosphere that would scatter sunlight back into space.
Emissions such as sulfate either help increase the reflectivity and extent of cloud cover over the Earth or scatter sunlight directly.
Skies polluted by volcanic ash scatter sunlight more, making sunsets show more red; similar results are seen with dust or man - made aerosols.
In short, Lindzen's argument is that the radiative forcing from aerosols is highly uncertain with large error bars, and that they have both cooling (mainly by scattering sunlight and seeding clouds) and warming (mainly by black carbon darkening the Earth's surface and reducing its reflectivity) effects.
2) A considerable part of that effect (apparently larger than thought before, according to the SOD) is produced by the direct effect; aerosols scatter sunlight and cool the surface.
The idea behind solar geoengineering is to constantly replenish a layer of small particles in the stratosphere, mimicking this volcanic aftermath and scattering sunlight back to space.
The aerosol hypothesis is that sulfate aerosols and black carbon are the main cause of global dimming, as they tend to act to cool the Earth by reflecting and scattering sunlight before it reaches the ground.

Not exact matches

Atmospheric aerosols are tiny particles that scatter and absorb sunlight but also influence climate indirectly through their role in cloud formation.
