'''Sulfate aerosol''' is particulate matter which consists of [[sulfur]] compounds formed by the interaction of [[sulfur dioxide]] and [[sulfur trioxide]] with other [[compound]]s in the [[atmosphere]]. Sulfate aerosols are injected into the atmosphere from the [[combustion]] of [[fossil fuels]] and the [[eruption]] of [[volcano]]es like [[Mt. Pinatubo]]. Recent theory suggests that sulfate aerosols may lower the [[Earth's temperature]] by reflecting away [[solar radiation]] (called negative [[radiative forcing]]). [[Climate model|Global climate model]]s which incorporate the effects of sulfate aerosols more accurately predict [[climate change|global temperature variations]].<ref>[http://earthobservatory.nasa.gov/Library/glossary.php3?mode=all NASA Earth Observatory glossary]</ref>
