– Stratospheric aerosol injection proposes releasing aerosols like sulfur dioxide (which forms sulfate aerosols) into the upper atmosphere to mimic the cooling effect observed after large volcanic eruptions.
– Both are geoengineering proposals aimed at increasing Earth’s albedo (reflectivity) or reducing the greenhouse effect of certain clouds.
– Creating artificial rain (Option A) is usually done by cloud seeding in lower atmospheric layers.
– While climate change affects tropical cyclones (Option B), these techniques are not specifically designed or guaranteed to reduce cyclone frequency or intensity, although changes in global temperatures could indirectly affect them.
– Solar wind (Option C) is a stream of charged particles from the Sun and is unrelated to these atmospheric techniques.
