Global change: Eruptions linked to El Niño

Statistical validation of a relationship between explosive volcanic eruptions and the El Niño/Southern Oscillation is a step forward in understanding the effects of such eruptions on climate.

One of the strongest influences on global climate is the cycle of events in the eastern and central tropical Pacific Ocean known as the El Niño/Southern Oscillation (ENSO). The cycle consists of periodic warming and cooling phases, El Niño and La Niña respectively, and conventional wisdom is that they are driven by natural interactions between the atmosphere and ocean in the tropical Pacific1.
