Broken Glass Yields Clues to Climate Change
December 27, 2010
A new study finds that microscopic particles of dust, emitted into the atmosphere when dirt breaks apart, follow similar fragment patterns as broken glass and other brittle objects. The research suggests there are several times more dust particles in the atmosphere than previously believed, since shattered dirt appears to produce an unexpectedly high number of large dust fragments.
