Pros and cons of stratospheric aerosol injection
International Journal of Global Warming, 2020Solar radiation management (SRM) geoengineering method of stratospheric aerosol injection (SAI) has been proposed to control global warming. The effect of sulphur injections at various locations in the stratosphere are studied by using climate models. These climate models have well-known limitations that are non-adequately addressed in the manuscript ...

Stratospheric aerosol injection research and existential risk
Futures, 2018Abstract In the wake of the continued failure to mitigate greenhouse gases, researchers have explored the possibility of injecting aerosols into the stratosphere in order to cool global temperatures. This paper discusses whether Stratospheric Aerosol Injection (SAI) should be researched, on the controversial ethical assumption that reducing ...

Trends in stratospheric contraction under sulfate aerosol injection
2023The change in the size and density of Earth’s atmospheric layers is a noticeable impact of human activity on climate. It is well known that the troposphere has been widening over the last decades, and a contraction of the stratosphere has been recently quantified. At stratospheric levels, the injection of sulphur dioxide into the stratosphere

Journal of Geophysical Research: Atmospheres
Abstract Stratospheric aerosol injection (SAI) introduces aerosols or their precursors into the stratosphere, reflecting sunlight and mitigating global warming. However, delivering these materials to the stratosphere at the required altitudes (18–25 km) poses practical challenges.

Legacy of stratospheric aerosol injection for limiting global warming
Despite significant advances in low emissions and renewable technologies, global warming is expected to exceed 2 degree and breach the Paris Agreement. Here we applied an Earth system model to simulate stratospheric aerosol injection (SAI) in idealized overshoot scenarios. The objective is to evaluate the impacts of avoiding temperature overshoot usingJerry Tjiputra +5 more

Impact of stratospheric aerosol injection on thermal environment shift
In this study, we applied the monthly mean near-surface temperatures from the historical and future projections under the SSP585 and G6 sulfur scenarios. The bias-correction and multi-model ensemble averaging were applied to the monthly mean near-surface temperatures from four models and then used to investigate the impact of Stratospheric Aerosol ...openaire +1 more source
