General Information
The ca. 4.2 - 3.9 ka BP abrupt aridification and cooling event is recorded globally, in many cases at high-resolution, but its causes, precise timing, qualities and quantification remain enigmatic.  A 3-day "4.2 ka BP event international workshop" will be held at the Dipartimento di Scienze della Terra (Università di Pisa), January  10-12,  2018, Pisa, Italy to present and discuss:
1. New high-resolution data for the quantification of the event, its dating, abruptness, magnitude and duration;
2. New syntheses of the event's regional climatic manifestation
3. Spatio-temporal explanations and modelling of the event

Approximately 50 participants are anticipated in addition to PhD and post-doctoral students.  Workshop sessions will be organized by regions and topics that will be specified after the deadline of abstract and program composition. Sessions will include 20-30 minute oral presentations and poster sessions. Solicited papers will open the thematic sessions, and a general discussion is scheduled to close the workshop.
The workshop will arrange for the publication of individual papers and potential synthesis papers in a special issue of an international peer reviewed journal.
The "4.2 ka BP event international workshop" will be free of charge, but travel and hotel expenses are not included. A list of convenient hotels will be provided on the web.  

We look forward greatly to your workshop participation.
