Although the speaker will address any topic relating to CAVEAT, the default lecture will discuss applying Catastrophic Thinking to global warming. The event will be preceded by an afternoon book signing session, if a book has been published. The event itself will follow the format of an early-evening two-hour stage presentation. The first hour will be a powerpoint presentation and the second hour will be a question-and-answer session where pre-event submitted questions will be addressed. There may be up to three sessions spread over Thursday to Saturday, if the event is open to the public and there is enough interest.
