radiation, i.e. the volcanic cloud can have an impact on the climate. As an
example, the eruption in Pinatubo in the Philippines occurred in 1991. In that
eruption about 20 million tons of sulfur dioxide (SO2) was released
into the stratosphere. The gas cloud was distributed around the
world, and
decreased sun radiation on the surface and because of that, caused a temporary
cooling of 0.5°C around
