Volcanic sulfur aerosols and climate change

New research of ice cores show even dormant volcanoes emit abundant sulfur into the atmosphere

Atmospheric sulfur aerosols are very important in terms of cloud nucleation and regulating solar radiation reaching Earth’s surface. Scientists recognized this effect after the eruption of Mount Pinatubo in 1991, which was one of the largest volcanic eruptions of the 20th century. The eruption released a significant amount of sulfur dioxide (SO2) gas an…
