Explosive Theory

Green is the lead author of a new study, published in the Proceedings of the National Academy of Sciences, asserting that volcanic activity may have been responsible for five mass extinction events in earth’s history—including the wipeout of the dinosaurs. Green began working on this research during his senior year at Dartmouth with earth sciences professor Brenhin Keller, who co-authored the study.

“Our results make it hard to ignore the role of volcanism in extinction,” says Keller.

According to Discover magazine: “These findings offer the strongest evidence of a causal connection between eruptions and extinctions, and suggest that volcanic activity constitutes the biggest cause of past die-offs, including the dinosaur decline.”
