WebApr 12, 2024 · China will die Klimaerwärmung stoppen, indem die Drohnen im grossen Stil Aerosole in die Stratosphäre bringen. Da sollen die Stoffe die Sonne reflektieren und so die Erderwärmung bremsen.

Stratospheric aerosol injection is a proposed method of solar geoengineering (or solar radiation modification) to reduce global warming. This would introduce aerosols into the stratosphere to create a cooling effect via global dimming and increased albedo, which occurs naturally from volcanic eruptions. … See more Materials Various forms of sulfur were proposed as the injected substance, as this is in part how volcanic eruptions cool the planet. Precursor gases such as sulfur dioxide and hydrogen sulfide have … See more The advantages of this approach in comparison to other possible means of solar geoengineering are: • Mimics a natural process: Stratospheric sulfur aerosols are … See more Early studies suggest that stratospheric aerosol injection might have a relatively low direct cost. The annual cost of delivering 5 million tons of an albedo enhancing aerosol … See more Solar geoengineering in general poses various problems and risks. However, certain problems are specific to or more pronounced with stratospheric sulfide injection. • Ozone depletion: a potential side effect of sulfur aerosols; and … See more Primary aerosol formation, also known as homogeneous aerosol formation, results when gaseous SO 2 combines with oxygen and water … See more It is uncertain how effective any solar geoengineering technique would be, due to the difficulties modeling their impacts and the complex nature of the global climate system. Certain efficacy issues are specific to stratospheric aerosols. • Lifespan … See more Almost all work to date on stratospheric sulfate injection has been limited to modeling and laboratory work. In 2009, a Russian team tested aerosol formation in the lower troposphere using helicopters. In 2015, David Keith and Gernot Wagner described a … See more WebIch untersuche, in Klimamodellen, die Auswirkungen einer künstlichen Schwefelaerosolschicht in der Stratosphäre auf das Klima. Zudem interessiert mich die Entwicklung des Schwefelaerosols vom der Emissions als Schwefeldioxid hin zum Aerosol, der Transport der Aerosole und die Auswirkungen auf die Dynamik der Stratosphäre. spongebob striped sweater gif
