Seasonal Injection Strategies for Stratospheric Aerosol Geoengineering [PDF]
Geophysical Research Letters, 2019 AbstractSimulations of stratospheric aerosol geoengineering have typically considered injections at a constant rate over the entire year. However, the seasonal variability of both sunlight and the stratospheric circulation suggests seasonally dependent injection strategies.

High‐Latitude Stratospheric Aerosol Injection to Preserve the Arctic
Earth's Future, 2023 Abstract Stratospheric aerosol injection (SAI) has been shown in climate models to reduce some impacts of global warming in the Arctic, including the loss of sea ice, permafrost thaw, and reduction of Greenland Ice Sheet (GrIS) mass; SAI at high latitudes could preferentially target these impacts.

Impact of the Latitude of Stratospheric Aerosol Injection on the Southern Annular Mode
Geophysical Research Letters, 2022 Abstract The impacts of Stratospheric Aerosol Injection (SAI) strategies on the Southern Annular Mode (SAM) are analyzed with the Community Earth System Model. Using a set of simulations with fixed single‐point SO 2 injections we demonstrate the first‐order dependence of the

Hemispherically symmetric strategies for stratospheric aerosol injection [PDF]
Earth System DynamicsStratospheric aerosol injection (SAI) comes with a wide range of possible design choices, such as the location and timing of the injection. Different stratospheric aerosol injection strategies can yield different climate responses; therefore ...

Radiometric Constraints on the Timing, Tempo, and Effects of Large Igneous Province Emplacement
Geophysical Monograph Series, Page 27-82., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The cost of stratospheric aerosol injection through 2100
Environmental Research Letters, 2020 This paper presents the estimated direct costs of a stratospheric aerosol injection (SAI) program through the end of this century. It displays a range of future solar geoengineering deployment scenarios that are intended to reduce anthropogenically ...

The impact of stratospheric aerosol injection: a regional case study
Frontiers in ClimateStratospheric aerosol injection (SAI) is a form of climate intervention that has been proposed to limit future warming and mitigate some of the adverse impacts of climate change while humanity continues efforts to reduce emissions and atmospheric concentrations of greenhouse gases.
