There is a press release here.
And apparently this is on top of the effects from sea level rise, of which rises measured by metres are not out of the question. I believe that a 1 cm rise in sea level equates to a greater increase in the high tide level, but I am not sure of this or of how much local topography determines that. Regardless, we clearly need more coastal states to pass laws dictating sea level will not get so out of hand!
