An Overview of Geoengineering of Climate using Stratospheric Sulfate Aerosols
1 We provide an overview of geoengineering by stratospheric sulfate aerosols. We review the state of understanding 2 about this topic as of early 2008, summarizing the past 30 years of work in the area, and highlight some very recent 3 studies using general circulation models of the atmosphere and ocean, and discuss the efficacy of producing such 4 aerosols by methods used to deliver sulfur spe...
متن کاملStratospheric Aerosol Geoengineering
In response to global warming, one suggested geoengineering response involves creating a cloud of particles in the stratosphere to reflect some sunlight and cool Earth. While volcanic eruptions show that stratospheric aerosols cool the planet, the volcano analog also warns against geoengineering because of responses such as ozone depletion, regional hydrologic responses, whitening of the skies,...
متن کاملStratospheric solar geoengineering without ozone loss.
Injecting sulfate aerosol into the stratosphere, the most frequently analyzed proposal for solar geoengineering, may reduce some climate risks, but it would also entail new risks, including ozone loss and heating of the lower tropical stratosphere, which, in turn, would increase water vapor concentration causing additional ozone loss and surface warming. We propose a method for stratospheric ae...
متن کاملStratospheric dynamics and midlatitude jets under geoengineering with space mirrors and sulfate and titania aerosols
The impact on the dynamics of the stratosphere of three approaches to geoengineering by solar radiation management is investigated using idealized simulations of a global climate model. The approaches are geoengineering with sulfate aerosols, titania aerosols, and reduction in total solar irradiance (representing mirrors placed in space). If it were possible to use stratospheric aerosols to cou...
