aerosol

Most climate models studying SAI assume the use of sulfate aerosols, similar to the compounds produced by volcanic eruptions.

But that sulphur also formed tiny, Sun-reflecting particles in the atmosphere, known as aerosols, which helped to keep a lid on rising temperatures.

Rapid urbanisation, industrial growth and land-use changes drove up fossil fuel use, vehicle emissions and biomass burning, sending aerosols into the atmosphere and dimming the Sun's rays.

Her approach consists of combining aerosol and seawater samples with sediment records, satellite data and lab microcosms to pin down cause and effect.

His addiction began with cannabis when he was a teenager and progressed to using aerosols and eventually heroin.
