I have been invited to participate in an online chat (text chat) on November 29th at 3:00 PM EST by the American Association for the Advancement of Science (AAAS, the publishers of the journal "Science"), discussing the "end of the world in 2012" as part of their "ScienceLive" web series: http://news.sciencemag.org/sciencelive/
My understanding is that David Morrison will also be participating. Further details to follow as I receive them.
