An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the eruption triggered an unusually cold winter, according to a Rutgers-led study. The study, in the Journal of Geophysical Research: Atmospheres, will help improve predictions of how the climate will respond to future high-latitude volcanic eruptions.
