Quizplus · Accepted Answer

Aerosols produced by sulfur dioxide emitted from the volcano can create a climate impact that lasts for a year or longer by reflecting sunlight back into space, causing a cooling effect on the climate. This phenomenon is known as volcanic winter. Ash suspended in the atmosphere or a high volume of debris ejected during the eruption can cause short-term climate impacts, but they typically do not last for a year or longer. The state of the climate at the time of the eruption may affect the severity of the impact but does not determine the duration of the impact.
