The eruption of Mount Pinatubo in June 1991 eventually affected almost half the planet after only a few weeks of circulation. The eruption injected significant amounts of sulfur dioxide (SO2) into the atmosphere, which converted to sulfuric acid (H2SO4) aerosols. These aerosols spread around the globe and resulted in a global cooling effect that was measured for several years. The eruption also caused a significant reduction in the ozone layer, affecting the Earth's climate and ecosystems.
