There's a twist in the story of volcanism and mass extinctions, say CCNY researchers

from City College of New York

An emerging scientific consensus is that gases — in particular carbon gases — released by volcanic eruptions millions of years ago contributed to some of Earth’s greatest mass extinctions. But new research at The City College of New York suggests that that’s not the entire story. “The key finding of our research is that carbon from massive, ancient volcanic eruptions does not line up well with the geochemical clues that tell us about how some of Earth’s most profound mass extinctions occurred,” said Benjamin Black, assistant professor in CCNY’s Division of Science, whose expertise includes effects of volcanism on climate and mass extinctions. more
