These pollutants are called aerosols and they include soot as well as compounds of nitrogen and sulfur and other stuff into the air.
这些污染物被称为气溶胶,它们包括煤烟以及空气中氮、硫和其他物质的混合物。
This would involve using sulphur or hydrogen sulphide aerosols so that sulphur dioxide would form clouds, which would, in turn, lead to global dimming.
这包括使用硫或硫化氢气溶胶,使二氧化硫形成云层,进而导致全球变暗。
'Geo-engineering plans to inject stratospheric aerosols or to seed clouds would act to cool the planet, and act to increase the extent of sea ice,' says Rasch.
