Stratospheric Aerosol Geoengineering ALAN ROBOCK ABSTRACT In response toglobal 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 strato-spheric aerosols cool the planet, the volcano analog also warns against 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 approach involves spraying reflective sulfate aerosol particles into the stratosphere with high altitude airplanes, tethered balloons, high-altitude blimps or artillery.
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. 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 the Whole Atmosphere Community Climate Model as its atmospheric component [CESM1(WACCM)], to investigate global and regional impacts of geoengineering. Since the beginning of stratospheric aerosol geoengineering the composition of what is being released into the stratosphere has been changed from silver iodide crystals to a more complex one. It is very hard to find trustworthy independent analysis of the released aerosols. SCoPEx: Stratospheric aerosol injection experiment David Keith, based at Harvard University, is the foremost geoengineering advocate advancing solar geoengineering.

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.

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. The perfect aerosol would not immediately tamper with stratospheric chemistry at all: “The only thing it would do is scatter maximum sunlight and hence cool down the planet.” Proponents of
This practice, known as stratospheric aerosol injection (SAI), involves attempting to reflect the sun’s light by spraying sulfur and other aerosols into the sky.

The 2D AER aerosol model was used to simulate geoengineering scenarios where global albedo is reduced with the help of stratospheric sulfuric acid aerosol enhancements. The AER model resolves all relevant microphysical processes in the formation of sulfuric acid aerosols after injection of SO 2 into the stratosphere.
However, the researchers point out that using solar geoengineering to hold global warming to 1.5C would not have the same environmental effect as reaching the target using mitigation. In summary, SAG (stratospheric aerosol geoengineering) is the intentional spraying of toxic heavy metal aerosol payloads with military and/or defense contractor, and/or commercial jet aircraft, for the stated goal of cooling the planet, or as stated in the Air Forces document, to control the weather over your enemy, or to deliver an aerosol agent that is chemical, biological or otherwise (and

In the geoengineering simulation, a constant stratospheric distribution of volcanic-sized, liquid sulfate aerosols is imposed in the period 2020–2050, corresponding to an injection of 2 Tg S/a. Bewi der Geoengineering-Technologie, Stratospheric Aerosol Injection, sollen Partikel in die obere Atmosphäre gesprüht werden, um das Sonnenlicht zu blockieren, Grafik: Geoengineering Monitor Unter Geoengineering versteht man groß angelegte Maßnahmen zur Intervention in den Ozeanen, Böden und der Atmosphäre der Erde mit dem Ziel, die Auswirkungen des Klimawandels - zumindest Abstract. 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.
