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 ...

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 ...

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 ...

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 ...

Assessing the consequences of including aerosol absorption in potential stratospheric aerosol injection climate intervention strategies [PDF]
Atmospheric Chemistry and Physics, 2022 Abstract. Theoretical stratospheric aerosol intervention (SAI) strategies model the deliberate injection of aerosols or their precursors into the stratosphere, thereby reflecting incident sunlight back to space and counterbalancing a fraction of the warming due to increased concentrations of greenhouse gases.
