question: what is geoengineering?

Geoengineering is deliberate, large-scale intervention in Earth’s natural systems to counteract climate change. The two most common forms are: SOLAR RADIATION MANAGEMENT (SRM) SRM techniques aim to reflect a small proportion of the Sun’s energy back into space, counteracting the temperature rise caused by increased levels of greenhouse gases in the atmosphere which absorb energy …

geoengineering explained: the benefits and challenges of stratospheric aerosols

Stratospheric aerosols are minute particles suspended in the atmosphere designed for solar radiation management [SRM]. When these particles are sufficiently large, their presence becomes noticeable as they scatter and absorb sunlight, which can reduce visibility [haze] and redden sunrises and sunsets. Aerosols interact both directly and indirectly with the Earth's radiation budget and climate. As …
