‘The Models Are Too Conservative’: Paleontologist Peter Ward on What Past Mass Extinctions Can Teach Us About Climate Change Today

by Ezra Buckley on September 10, 2017

This week, to accompany our cover story on worst-case climate scenarios, we’re publishing a series of extended interviews with climatologists on the subject — most of them from the “godfather generation” of scientists who first raised the alarm about global warming several decades ago.

Peter Ward is one of the paleontologists responsible for overturning our understanding of most of the Earth’s mass extinctions, which, long thought to be caused by asteroid impacts, turned out to have been the result of climate change produced by greenhouse gases (all but the one that killed the dinosaurs, anyway).
