Reply [to “Snowbird II: Global catastrophes comment: Meteorite impact, mass extinction and Deccan volcanism”]



I did not intend my report on the Global Catastrophes meeting to rule out a contributing role for volcanism in the history of terrestrial mass extinctions. Nor did I suggest that there was necessarily no relationship between impacts and some volcanism. Indeed, I reported on evidence that might link periodic impacts with periodic terrestrial volcanism, an idea that Hooper advocates. But Hooper's argument that Deccan volcanism was integrally responsible for the K-T extinctions is not compelling.
