In this exclusive interview series, we talk to Jaan Tallinn (Co-Founder of Skype and Cambridge Centre for the Study of Existential Risk), Professor Sir John Beddington (Senior Advisor, Oxford Martin School & the UK Government’s former Chief Scientific Adviser) and Sir Crispin Tickell (former diplomat and advisor to successive UK Prime Ministers, who is regarded as the world’s foremost authority on climate change and environmental issues).  We tackle the question of how vulnerable our species really is and explore threats ranging from climate change and natural disasters to food, energy and water security, technology, artificial intelligence, near earth objects and the biggest threat to humanity… humans themselves.
