29 Oct 2018 Spraying aerosols high in the stratosphere could dampen global warming over land, but may not prevent the oceans from heating up, new 

often referred to collectively as geoengineering, that potentially could has gained my personal attention is “stratospheric aerosol injection” 

It is only recently possible to simulate SA geoengineering in climate models that simultaneously include many essential processes, including aerosol microphysical growth (how injections of S O 2, for example, oxidize into H 2 S O 4 and form sulfate aerosols through condensation and coagulation), stratospheric chemistry (including changes to ozone and water vapor concentrations), a sufficiently spatially resolved stratosphere to capture important dynamic processes influencing aerosol Solar geoengineering refers to proposed approaches to cool the Earth by reflecting solar radiation back to space. The two main approaches being researched are stratospheric aerosol injection (SAI) and marine cloud brightening (MCB). Stratospheric aerosols are a key component of solar geoengineering technology that some have proposed as a plan B for controlling the Earth’s temperature if the climate crisis makes conditions Geoengineering with stratospheric sulfate aerosols can, to some extent, be designed to achieve different climate objectives. Here we use the the state-of-the-art Community Earth System Model, version 1, with the Whole Atmosphere Community Climate Model as its atmospheric component (CESM1(WACCM)), to compare surface climate and stratospheric effects of two geoengineering strategies. If geoengineering were halted all at once, there would be rapid temperature and precipitation increases at 5–10 times the rates from gradual global warming. Stratospheric temperature change: Aerosols can also absorb some radiation from the Sun, the Earth and the surrounding atmosphere. This changes the surrounding air temperature and could potentially impact on the stratospheric circulation, which in turn may impact the surface circulation.

2018-11-23 · Although controversial, some think that trying to mimic the impacts of a volcano eruption is a viable way to control global warming. This proposed type of climate geoengineering is called Large-scale technological interventions to “fix” the climate crisis are moving up on the political agenda. Some climate scientists are now proposing geoengin Stratospheric aerosol injection (SAI) might alleviate some climate risks associated with accumulating greenhouse gases. Reduction of specific process uncertainties relevant to the distribution of aerosol in a turbulent stratospheric wake is necessary to support informed decisions about aircraft deployment of this technology. 2016-04-23 · Geoengineering, Weather Modification, Stratospheric Aerosols, Chemtrails - Undeniable and Verifiable Airplanes spraying the sky everyday. 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.

These sections show that past experience with explosive volcanic eruptions suggest that injecting sulfate aerosols into the stratosphere could, at least in gross  23 Jan 2020 One is to inject sulfur dioxide or a similar aerosol into the stratosphere to help shade the Earth from more intense sunlight.

Stratosfärisk aerosolinjektion - Stratospheric aerosol injection på resultaten från 2014-2015 Geoengineering Model Intercomparison Project, 

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 Se hela listan på large.stanford.edu Stratospheric aerosol geoengineering (SAI) seeks to mimic the effects of volcanic eruptions that inject sulfur compounds into the lower stratosphere 11. We provide an overview of geoengineering by stratospheric sulphate aerosols. The state of understanding about this topic as of early 2008 is reviewed, summarizing the past 30 years of work in the area, highlighting some very recent studies using climate models, and discussing methods used to deliver … Unlike many other geoengineering interventions, stratospheric aerosol injection has no additional societal co-benefits: its sole raison d’etre would be to offset planetary heating caused by rising concentrations of greenhouse gases.

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

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.

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.

It is patterned after a  5 Jun 2020 Scientists model the effects of spraying aerosols into the stratosphere cooling strategy that uses solar geoengineering to limit the amount of  We provide an overview of geoengineering by stratospheric sulphate aerosols.

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. 2020-03-19 · Stratospheric aerosol geoengineering, a proposal to add reflective aerosols to the stratosphere, might reduce the risks of climate change if used in combination with emissions cuts, carbon removal, and adaptation.

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.

Contrails  “Solar geoengineering – injecting aerosol particles into the stratosphere to reflect away a little inbound sunlight – is being discussed as a way  Aerosolbesprutningen (utskottsförhör Kalifornien) Levande trådar i Här finns en bättre version av videon Geoengineering i #20. Ett annat uttryck för chemtrails som börjat användas av CIA är stratospheric aerosol injection (wiki). Troligen är  Stratospheric Aerosol Geoengineering. A former KLM Lund igång ?
