摘要: It has long been estabished that gas and fine ash from large equatorial explosive eruptions can spread globally, the sulphuric acid is consequently produced in stratosphere cause a small, but statistically significant, cooling of global temperatures1,2. Central to revealing ancient volcano–climate connection have studies linking single features climate-proxy records such as found ice-core3,4,5 tree-ring6,7,8 chronologies. Such also suggest known inventory incomplete, climatic significance unreported or poorly understood remains be revealed. The AD 1600 eruption Huaynaputina, southern Peru, speculated one largest past 500 years; acidity spikes Greenland Antarctica ice3,4,5, tree-ring chronologies6,7,8, along with atmospheric perturbations early seventeenth-century Europe China9,10, implicate an similar greater magnitude than Krakatau 1883. Here we use tephra deposits estimate volume Huaynaputina eruption, it was indeed historic times. chemical characteristics glass juvenile allow firm cause–effect link established Antarctic ice, thus improve on estimates stratospheric loading eruption.
