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 ]
Injecting reflective aerosols into the stratosphere is the proposed SRM method that has received the most sustained attention. The Intergovernmental Panel on Climate Change concluded that Stratospheric aerosol injection "is the most-researched SRM method, with high agreement that it could limit warming to below 1.5 °C."
Among the multiple potential approaches, stratospheric aerosol injection is the most-studied, followed by marine cloud brightening. SRM could be a temporary measure to limit climate-change impacts while greenhouse gas emissions are reduced and carbon dioxide is removed , [ 45 ] but would not be a substitute for reducing emissions.
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 ...
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 , carbon dioxide removal , and adaptation , would reduce climate change and ...

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.
