Pinatubo eruption 1991 cooling effect
WebMar 5, 2000 · Mount Pinatubo, June 13, 1991 (Image courtesy of NOAA). Major eruptions alter the Earth's radiative balance because volcanic aerosol clouds absorb terrestrial radiation, and scatter a significant amount of the incoming solar radiation, an effect known as "radiative forcing" that can last from two to three years following a volcanic eruption.
