Leanan:  Yesterday I noticed some comments on ocean level rise. Here is an excellent study on the pacific ocean area by the Australian government. Thru 2006. 3.8 Megs

To put that Reuters artical in perspective: A net loss of 27 cubic miles of Greenland ice/year is equal to 3.2 mm of ocean rise in ten years.

For the metric challenged, 1/8th of an inch.

Note though that even this small rise will increase shoreline erosion. Depending upon soil/sand types, anything steeper than a 50:1 rise is unstable#, so one would expect the shorelines to be pushed back by a half foot or so.  More next decade.

Best Hopes,

Alan

#Vague memory on slope.  Anyone have better #s ?
