Scientists have used an innovative combination of observations and computer models to quantify aerosols in the atmosphere from volcanic eruptions. These sulfate aerosols cool the Earth's surface. Volcanic activity since 2005 may have significantly reduced rates of global warming. (Animation by Michael Mills, NCAR.)Reference:
