Why do sea level rise rates vary by location?

i would expect up there it is isostatic rebound from the last glaciation, like in Scotland.

I haven't been contributing the last few weeks, so forgive me if this report has surfaced elsewhere, but I thought this group could benefit from a review of a report recently provided by the Pacific Institute of Oakland regarding sea level rise in California.  The full report is 131 pages, I believe, so I linked the executive summary (9 pages) and the interactive maps link.  Well worth your time to take a peek.

what gave me pause for thought was this

Sea Level Rise Due To Global Warming Poses Threat To New York City

the gulf stream makes the sea bulge up in mid atlantic. if it eases, the water slops towards the shore. i expect this happens elsewhere also.

Once again you have provided me with an article and I link I hadn't seen before.

What caught my eye in the Pacific Institute report was singling out 2 counties, one of which is where I live!  Fortunately I took geology in college and purchased a home well above the flood plain.  But I have friends who could ultimately be in harms way, and regardless, this kind of information, east coast or west, U.S.A. or Great Britain or elsewhere, should help people focus not only on global climate change but on development in general.
