Eine künstliche stratosphärische Schwefelschicht: Der einfache Ausweg aus dem Klimaproblem?

An artificial stratospheric sulphur layer: The easy way out of the climate problem?: Sulfur, artificially introduced into the stratosphere (stratospheric aerosol intervention, SAI), forms small sulfur particles that scatters sunlight and thereby cools the Earth's surface. This chapter discusses the effects of SAI on climate and ozone, as well as the formation of the sulfur aerosols. Climate models simulate the consequences of SAI, with significant differences between models. This results in uncertainties in the climate impact, but also in the amounts of sulfur injection needed in the models to achieve a specific global temperature reduction.
