Question

Quizplus · Accepted Answer

Volcanic eruptions can release large quantities of ash and aerosols into the atmosphere, which can block incoming solar radiation and cause global temperatures to decrease. This has been observed in the past, such as after the eruption of Mt. Pinatubo in 1991, which caused a cooling effect on global temperatures for several years.
