The volcano that changed the climate

The eruption of Mount Pinatubo in 1991 led to a temporary drop in global temperature. This illustrated that tiny particles ejected into the atmosphere have the potential of changing the Earth's climate. This aerial view to the south of the Pinatubo crater shows the start of a small explosion on August 1, 1991. Photo: T. J. Casadevall / USGS.
