  Near earth object project

Papers and presentations from the 2007 Planetary Defense conference. I was supposed to present here, and helped organize Session 5. At the last minute I was asked to give some presentations to the Swedish Defense Ministry.

As part of my continuing work on "extreme events" and worst cases, I've been writing on the problem of "near earth objects." In May 2002 I presented a paper in a day-long workshop at the Western Psychological Association, on the lessons that social science might bring to NEO-related issues.

In February 2002 I presented similar work at the American Association for Advancement of Science meetings.

I participated in a "Planetary Defense Conference" in February 2004, which was sponsored by American Institute of Aeronautics and Astronautics and The Aerospace Corporation. A video of my presentation is here.
