This paper describes the Stratospheric Aerosol Geoengineering Large Ensemble (GLENS) project, which promotes the use of a unique model dataset, performed with the Community Earth System Model The G4 stratospheric aerosol geoengineering was relatively less effective in increasing cold spell duration and decreasing warm spell duration in equatorial oceans than G1 solar dimming geoengineering, consistent with a relatively smaller cooling effect in coldest day and warmest night in equatorial oceans than in adjacent regions. Scientists and governments refer to, what is commonly known around the world as Chemtrails (not to be confused with normal jet contrails), as Stratospheric Aerosol Geoengineering (S.A.G.). It has been documented, as far back as the late 1980’s, that the United States (U.S.) Government has been conducting covert S.A.G. programs.

The Geoengineering Model Intercomparison Project, conducting climate model experiments with standard stratospheric aerosol injection scenarios, found that insolation has reduction could keep the global average temperature constant, but global average precipitation would reduce, particularly in summer monsoon regions around the world. By reflecting some incoming solar radiation, stratospheric aerosol intervention using SO 2 would reduce global mean temperature. Previous research has shown that multiple injection latitudes can be used to maintain not only global mean temperature, but also interhemispheric and equator‐to‐pole temperature gradients. Abstract.

Abstract. [1] Injecting sulfate aerosol precursors into the stratosphere has been suggested as a means of geoengineering to cool the planet and reduce global warming. The decision to implement such a scheme would require a comparison of its benefits, dangers, and costs to those of other responses to global warming, including doing nothing.

Stratospheric aerosol geoengineering is the idea that adding a layer of aerosol particles to the upper atmosphere can reduce climate changes caused by greenhouse gases such as carbon dioxide. Geoengineering by stratospheric aerosol injection has been proposed as a policy response to warming from human emissions of greenhouse gases, but it may produce unequal regional impacts.

1-3 Stratospheric aerosol injection (SAI Lifting options for stratospheric aerosol geoengineering: advantages of tethered balloon systems Peter Davidson Davidson Technology Limited, 8a Village Walk, Onchan, Isle of Man Stratospheric aerosol injection is a solar radiation management (srm) geoengineering or climate engineering approach that uses tiny reflective particles or aerosols to reflect sunlight into space in order to cool the planet and reverse or stop Global Warming. The ability of stratospheric aerosols to create a global dimming effect has made them a possible candidate for use in solar radiation management climate engineering projects to limit the effect and impact of climate change due to rising levels of greenhouse gases. Delivery of precursor sulfide gases such as sulfuric acid, hydrogen sulfide or sulfur dioxide by artillery, aircraft and balloons has been proposed. Non-sulfide substances such as calcite have also been proposed given The concept of stratospheric aerosol geoengineering involves adding a layer of aerosol particles to the upper atmosphere to decrease climate changes due to greenhouse gases like carbon dioxide. 2015-04-02 · The Geoengineering Model Intercomparison Project, conducting climate model experiments with standard stratospheric aerosol injection scenarios, has found that insolation reduction could keep the global average temperature constant, but global average precipitation would reduce, particularly in summer monsoon regions around the world.

Numerous climate modeling studies have shown that while no solar geoengineering technique can completely reverse the climate change caused by elevated atmospheric GHG concentrations, they may be able to offset a large fraction of the changes in several key climate variables, such as temperature and precipitation, thus potentially reducing climate risks. 1-3 Stratospheric aerosol injection (SAI stratospheric aerosol geoengineering.

24 Jul 2019 Stratospheric aerosol injection (SAI) is the most researched of a suite of technologies aimed at cooling the Earth known as "solar geoengineering" 

This paper describes the Stratospheric Aerosol Geoengineering Large Ensemble (GLENS) project, which promotes the use of a unique model dataset, performed with the Community Earth System Model, with Solar geoengineering using stratospheric sulfate aerosols has been discussed as a potential means of deliberately offsetting some of the effects of climate change (Crutzen 2006). Various model studies have demonstrated that reducing incoming solar radiation globally can offset the increase in global average surface temperature associated with increasing greenhouse gases (e.g., Kravitz et al. 2013 ). The concept of stratospheric aerosol geoengineering involves adding a layer of aerosol particles to the upper atmosphere to decrease climate changes due to greenhouse gases like carbon dioxide. This research focused on one particular SRM approach, called stratospheric aerosol injection, which involves releasing reflective particles into the stratosphere. The paper lays out an agenda for The G4 stratospheric aerosol injection geoengineering introduces a more effective reduction in TOA net radiation over the Northern Hemisphere, especially over the high-latitude continents, such as northern North America, Siberia and some regions of western Europe.
