The eruption of Mount Pinatubo on 15 June 1991 produced the largest stratospheric volcanic aerosol cloud of the 20th century. About 20 megatons of SO2 was injected into the stratosphere, affecting global climate for years. In his Perspective, Robock discusses the climatic lessons learned from the Pinatubo eruption. An accompanying Perspective by Newhall et al. discusses the geologic insights gained from the eruption.
