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 ]
In 2014, an attempt to stop climate change via stratospheric aerosol injection catastrophically backfires, creating a new ice age that destroys much of life on Earth. For 17 years, the remnants of humanity shelter in a state-of-the-art self-sustaining circumnavigational train, the Snowpiercer, run by reclusive transportation magnate Wilford.
Stratospheric aerosol injection (SAI) is the most studied and has the most cost estimates. UNEP reported a cost of $18 billion per degree, [ 7 ] : 32 although individual studies have estimated that SAI deployment could cost between $5 billion to $10 billion per year.
Although there's a popular narrative that stratospheric aerosol injection can be carried out by individuals, small states, or other non-state rogue actors, scientific estimates suggest that cooling the atmosphere by 1 °C (1.8 °F) through stratospheric aerosol injection would cost at least $18 billion annually (at 2020 USD value), meaning that ...
Among the potential methods, stratospheric aerosol injection (SAI) is the most-studied, [45]: 350 followed by marine cloud brightening (MCB); others such as ground- and space-based methods show less potential or feasibility and receive less attention.
Stratospheric sulfur aerosols spread around the globe by the atmospheric circulation, producing surface cooling by scattering solar radiation back to space. This cooling effect on the ocean surface usually lasts for several years as the lifetime of sulfate aerosols is about 2–3 years. [ 1 ]

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 ...
