Sulfate aerosols
Particulate matter that consists of compounds of sulfur formed by the interaction of sulfur dioxide and sulfur trioxide with other compounds in the atmosphere. Sulfate aerosols are injected into the atmosphere from the combustion of fossil fuels and the eruption of volcanoes like Mt. Pinatubo. Recent theory suggests that sulfate aerosols may lower the earth's temperature by reflecting away solar radiation (negative radiative forcing). General Circulation Models which incorporate the effects of sulfate aerosols more accurately predict global temperature variations. See particulate matter, aerosol, General Circulation Models. (source: EPA) 0 Wall Street JournalVolcanoes -- when they erupt and inject millions of tons of fine particulate material into the stratosphere (mostly sulfate aerosols) -- have also cooled Scientists Wary of Iron as Proposed Climate Fix - Oct 15, 2007 NPRFor example, they have discussed the idea of releasing sulfate aerosols or dust into the atmosphere. The dust would reflect light and thus cool the Earth.
