Another forcing of climatic change involving solar input is the aerosol concentration coming from volcanic activity. It is estimated that the 1992 eruption of Mt. Pinatubo produced a global mean temperature decrease of about ________ degrees Celsius.
A. 0.1
B. 0.4
C. 1.1
D. 2.3

Large scale Volcanoes such as that of Mount Pinatubo, have an effect on climate worldwide. The volcano ejected ash and gases into the stratosphere, preventing radiation from the sun from reaching the surface of the earth, thereby reducing the global mean temperature. It is estimated that this volcanic activity reduced global temperature by approximately 0.4°C.
