Dirty Volcanic Eruption In Chile Can Change Climate
A mid-sized volcano in Chile is having a major-sized volcanic event. If it blows off its crown, it can change global weather. It all depends on volume, power of the explosive forces breaking out into the stratosphere and the mass of ejected particulate matter and aerosol gases. We have had several 'cooling off' periods caused by volcanos during my lifetime. And in history, volcanic activity has pushed forwards evolution and has caused mini-ice ages as well as starvation and privations. Indeed, some huge volcanic eruptions have nearly killed off all homo sapiens in Africa long ago. Only about 2,000 humans survived the effects of a major volcano in Sumatra blowing up. Volcanos are the engines of evolution just as meteorites can alter the course of nature.
