In 1784 the temperature of the northern hemisphere dropped 1 ° C after the Laki volcanic system in Iceland was active for 8 months. More recently, after the eruption of the Philippine Mount Pinatubo in 1991, the boreal hemisphere cooled 0.6 ° C. The fury of a volcano brings cold times , and the reason is in its emissions.
