A new study in Nature warns of global unpreparedness for the next major volcanic eruption, potentially causing unprecedented climate chaos. Historical eruptions like Tambora in 1815 caused significant cooling and widespread devastation. There's a one-in-six chance of a similar event this century, with projected economic losses exceeding $3 trillion in the first year. Climate change complicates matters, altering atmospheric conditions and ocean systems. Scientists urge improved climate models incorporating volcanism and agricultural impacts to better prepare for the inevitable.
