26 Feb 2015: I have posted a correction to the talk text of my Dec 2014 talk at the Vienna Conference on the Humanitarian Impact of Nuclear Weapons. To my embarrassment, I gave the wrong numbers for my own research on the probability of Russia-US inadvertent nuclear war. My latest Bulletin of the Atomic Scientists column is up: Stopping killer robots and other future threats. The Campaign to Stop Killer Robots is an active campaign against fully autonomous weapons. It is a great example of how to confront threats from future technologies before those technologies exist.
5 Feb 2015: I have new paper coming out. The most extreme risks: Global catastrophes will be published in a book on edited by Vicki Bier. The paper presents some ethical and analytical challenges posed by global catastrophic risks and proposes an integrated assessment research agenda for studying the risks.

In other news, I'm just back from a trip to England, where I visited colleagues at the Centre for Study of Existential Risk at Cambridge University and the Future of Humanity Institute at Oxford University. Exciting things going on there. I'm honored to be speaking at the Vienna Conference on the Humanitarian Impact of Nuclear Weapons coming up in December, though it does mean I must miss the Society for Risk Analysis 2014 Annual Meeting. Finally, after 6 years of neglect, the photos page has been updated.
2 Aug 2014: A new paper has been accepted for publication. Integrating the planetary boundaries and global catastrophic risk paradigms, co-authored with Itsuki Handoh, will appear in Ecological Economics.
