This blog is about our existential emergency – the combination of catastrophic threats which we humans are creating that imperil our own future and that of all our descendants. It’s not a palatable subject, but it is, quite simply, the most important issue facing humanity today. There is nothing that tops it. Yet it gains minimal attention.

Existential risk is a respectable academic discipline, with research centres at Oxford and Cambridge universities – but it is a topic you rarely see in media headlines, or hear from the lips of politicians and civic leaders. Yet it concerns your fate, and that of every person on the planet. It rules the future of our civilisation, maybe the entire human species.

These blogs and oped articles are intended to encourage inquiry and the discussion we humans have to have if we intend to survive this Century, when ten mega-risks come together to confront us. They are intended, especially, to encourage discussion of cross-cutting species-level solutions. Please feel free to share, debate and make your own investigation.
