High‐Latitude Stratospheric Aerosol Injection to Preserve the Arctic
Earth's Future, 2023 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 ...

Potential for perceived failure of stratospheric aerosol injection deployment. [PDF]
Proc Natl Acad Sci U S A, 2022 As anthropogenic activities warm the Earth, the fundamental solution of reducing greenhouse gas emissions remains elusive. Given this mitigation gap, global warming may lead to intolerable climate changes as adaptive capacity is exceeded. Thus, there is emerging interest in solar radiation modification, which is the process of deliberately increasing ...

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

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.

Comparison of primary aerosol emission and secondary aerosol formation from gasoline direct injection and port fuel injection vehicles [PDF]
Atmospheric Chemistry and Physics, 2018 Gasoline vehicles significantly contribute to urban particulate matter (PM) pollution. Gasoline direct injection (GDI) engines, known for their higher fuel efficiency than that of port fuel injection (PFI) engines, have been increasingly employed in ...

Geophysical Research Letters, 2023 Stratospheric Aerosol Injection (SAI) aims to offset some climate hazards by injecting aerosols into the stratosphere to reflect solar radiation. The lifetime of injected particles influences SAI's radiative efficacy—the ratio of radiative forcing to ...

Low‐Altitude High‐Latitude Stratospheric Aerosol Injection Is Feasible With Existing Aircraft
Earth's FutureStratospheric aerosol injection (SAI) is a proposed method of climate intervention in which aerosols or their precursors would be injected into the stratosphere to reduce or halt global warming.

Dependency of the impacts of geoengineering on the stratospheric sulfur injection strategy – Part 1: Intercomparison of modal and sectional aerosol modules [PDF]
Atmospheric Chemistry and Physics, 2022 Injecting sulfur dioxide into the stratosphere with the intent to create an artificial reflective aerosol layer is one of the most studied options for solar radiation management.
