Large tropical volcanoes have caused some of the world’s most destructive natural disasters, with eruptions spewing out massive streams of harmful gases and hot debris that can wipe out everything in their path. But, what about wider impacts on global climate? Large eruptions are well known to temporarily cool the planet, but the picture is less clear when it comes to changes in the global distribution of rainfall.
In a new study, a team of researchers from Columbia University’s Lamont-Doherty Earth Observatory, the University at Albany and other institutions have used natural climate archives such as tree rings to better understand big eruptions’ global hydroclimate impacts over the past 1,000 years.
