Volcanoes, Climate and Mass Extinction in Earth History
Blair Schoene, professor of geosciences and associated faculty in HMEI, will present “Volcanoes, Climate and Mass Extinction in Earth History” for the second talk in our spring 2022 HMEI Faculty Seminar Series.
Schoene will discuss efforts to measure the eruption timescales of volcano clusters known as large igneous provinces to test whether massive outpourings of volcanic gasses could have contributed to the end-Cretaceous mass extinction 66 million years ago. This work has substantiated the idea that volcanism — combined with a meteorite impact — contributed to the event, but there remain large uncertainties that could reveal more about how Earth’s climate responded to catastrophic volcanism, a meteorite impact, and ecosystem collapse.
John Higgins, associate professor of geosciences and HMEI associated faculty, will lead a discussion and Q&A after the main presentation.
