The U.S. Global Change Research Information Office (GCRIO) hosts the
on-line version of "The Probability of Sea Level Rise" by James G. Titus
and Vijay K. Narayanan, a 1995 publication. The report is located at
http://www.gcrio.org/EPA/sealevel/seatitle.html
The hard copy of the report can be obtained from the EPA by contacting the
National Center for Environmental Publications and Information (NCEPI), PO
Box 42419, Cincinnati OH 45242 USA. NCEPI also can be reached at
1-513-489-8190 (phone), and 1-513-489-8695 (fax).
In addition, the Working Group II contribution to the Intergovernmental
Panel on Climate Change (IPCC) Second Assessment Report contains a
chapter on the effects of climate change on coastal zones and small
islands. The report is available from Cambridge University Press.
Executive Summaries of the WG II report are available on-line at
http://www.unep.ch/ipcc/ipcc95.html
Hard copies of the Executive Summary are available from the GCRIO
and can be ordered free using our Document Request Form
http://www.gcrio.org/OnLnDoc/docreq-form.html
Hope this helps.

Andy & Sophie,
The state of the models is not very good. The modelers will tell you that.
If you move to the seaside, just make sure you are at a proper elevation
and distance from the shore to avoid storm surge from any major storm.
Maybe in 10-20 years the models will have most of the physics in them and
the computers will be powerful enough to model the atmosphere. IMHO, we are
not there yet.

Subject: ocean model sponge layers

Has anyone had experience, or know of published results, of using
sponge layers in ocean models as a way of dealing with open boundaries
with *strong* flows. Everything I've found (eg North Atlantic CME model)
uses them where there are relatively weak flows into or out of the
sponge. I'm wanting something of the order of 100Sv...
Any responses welcomed!
Thanks,
- Andrew Woolf
