Aerosol Eruptions

    Newer Older

    Volcanoes produce ash and prodigious amounts of sulfur dioxide, a colorless gas with a pungent odor. Sulfur dioxide interacts with air to produce sulfate aerosols. Volcanoes can launch sulfates high into the stratosphere, where they can persist for years. Global temperature fell by half a degree when just one volcano—Mount Pinatubo—erupted in 1991 and produced large amounts of light-reflecting sulfates, which act like a mirror over Earth, reflecting radiation away from the surface.
