Is it possible to develop a unified science of catastrophic risk? How can we convince policymakers to take risks to human existence seriously enough? How can we improve our foresight so that we can spot the next big disaster before it hits us?

Dr Clarissa Rios Rojas discusses these questions with Toby Wardman of SAPEA. We also discuss how to start a difficult conversation with a politician, whether future doomsday manuals should be stuffed into envelopes or just put online, and why being a scientist is cool.
