Impacts of three types of solar geoengineering on the Atlantic Meridional Overturning Circulation [PDF]

Atmospheric Chemistry and Physics, 2022
Climate models simulate lower rates of North Atlantic heat transport under greenhouse gas climates than at present due to a reduction in the strength of the Atlantic Meridional Overturning Circulation (AMOC).

Brief communication: Understanding solar geoengineering's potential to limit sea level rise requires attention from cryosphere experts [PDF]

The Cryosphere, 2018
Stratospheric aerosol geoengineering, a form of solar geoengineering, is a proposal to add a reflective layer of aerosol to the stratosphere to reduce net radiative forcing and so to reduce the risks of climate change.

Deliberating stratospheric aerosols for climate geoengineering and the SPICE project [PDF]

Nature Climate Change, 2013
Increasing concerns about the narrowing window for averting dangerous climate change have prompted calls for research into geoengineering, alongside dialogue with the public regarding this as a possible response. We report results of the first public engagement study to explore the ethics and acceptability of stratospheric aerosol technology and a ...

Impact of stratospheric aerosol intervention geoengineering on surface air temperature in China: a surface energy budget perspective [PDF]

Atmospheric Chemistry and Physics, 2022
Stratospheric aerosol intervention (SAI) geoengineering is a proposed scheme to counteract anthropogenic global warming, but the climate response to SAI, with great regional disparities, remains uncertain.

Quantifying the Efficiency of Stratospheric Aerosol Geoengineering at Different Altitudes

Geophysical Research Letters, 2023
AbstractStratospheric aerosol injection (SAI) of reflective sulfate aerosols has been proposed to temporarily reduce the impacts of global warming. In this study, we compare two SAI simulations which inject at different altitudes to provide the same amount of cooling, finding that lower‐altitude SAI requires 64% more injection.

Data from: High-latitude stratospheric aerosol geoengineering may be more effective if injection is limited to spring

, 2021
Stratospheric aerosol geoengineering focused on the Arctic could substantially reduce local and worldwide impacts of anthropogenic global warming. Because the Arctic receives little sunlight during the winter, stratospheric aerosols present in the winter

Atmosphere–ocean–aerosol–chemistry–climate model SOCOLv4.0: description and evaluation [PDF]

Geoscientific Model Development, 2021
This paper features the new atmosphere–ocean–aerosol–chemistry–climate model, SOlar Climate Ozone Links (SOCOL) v4.0, and its validation. The new model was built by interactively coupling the Max Planck Institute Earth System Model version 1.2 (MPI-ESM1 ...
