1991年6月皮纳图博火山（菲律宾）喷发期间向平流层注入了大量硫，随后形成了硫酸盐气溶胶颗粒，在大气中产生了许多扰动，对地球气候有潜在影响。火山喷发引起的太阳和红外辐射收支的变化应该会使对流层变冷，平流层下层变暖。这些变化可能影响大气环流。此外，硫酸盐气溶胶颗粒表面的非均相化学反应使臭氧分子更容易受到大气氯的影响，从而更容易受到人造氟氯化碳的影响。
The injection into the stratosphere of large quantities of sulfur during the June 1991 eruption of Mount Pinatubo (Philippines) and the subsequent formation of sulfate aerosol particles have generated a number of perturbations in the atmosphere with potential effects on the Earth's climate. Changes in the solar and infrared radiation budget caused by the eruption should produce a cooling of the troposphere and a warming of the lower stratosphere. These changes could affect atmospheric circulation. In addition, heterogeneous chemical reactions on the surface of sulfate aerosol particles render the ozone molecules more vulnerable to atmospheric chlorine and hence to man-made chlorofluorocarbons.
