Volcanism, impacts and mass extinctions
Episode 22
Was the extinction event that brought down the dinosaurs the biggest in history? What causes mass extinction events, and how do we know about them? And perhaps the biggest question of all - are we heading for a mass extinction of a similar scale now?
Sarah visits the Natural History Museum, where a multidisciplinary conference has brought together researchers to discuss mass extinctions, their causes and effects. Gerta Keller, who organised the conference, explains its motivations and outcomes, alongside Andrew Kerr, Thierry Adatte and Anja Schmidt.
