text: Scientists tracking the effects of the major 1991 eruption of the Philippines’ Mt. Pinatubo found that the overall effect of the blast was to cool the surface of the Earth globally by some 0.5 degrees Celsius a year later, even though rising human greenhouse gas emissions and an El Nino event (a warm water current which periodically flows along the coast of Ecuador and Peru in South America) caused some surface warming during the 1991-1993 study period.
