Subsidence is a local phenomena. Subsidence (3 mm/yr) + global sea level rise (about 3 mm/yr) + other local phenomena = local mean sea level rise. Tides change sea level by about 1000 mm twice day. Northeasters add a storm surge of 1000 mm (every few years) to 2000 mm (every few decades) to the sea level in Norfolk. The only thing that is currently new in recent decades an 1 additional mm of global sea level rise every year.

Yea, it will be interesting to see how infrastructure is replaced, in the coming era where sea level is quite obviously not static, and how it's built so it doesn't need to be rebuilt again 50 years later. At some point people will be going to beaches while knowning they won't be there in a few more decades. That would be a strange feeling.David Appellhttps://www.blogger.com/profile/03318269033139447591noreply@blogger.comtag:blogger.com,1999:blog-28837843.post-48107853474148227462014-06-04T10:10:24.433-07:002014-06-04T10:10:24.433-07:00Thanks for this link to a very informative source....Thanks for this link to a very informative source. <br /><br />Like much of the original Norfolk, its namesake in Virginia appears to be largely low-lying and very vulnerable to the sea level rise expected over coming centuries as ice caps melt. <br /><br />Where the land is more hilly, even in seaports many built-up areas will remain above sea level, but harbours, access roads and railways will need to be rebuilt so major disruption. <br /><br />Replacing necessary infrastructure will be a major undertaking at a time when resources will be under strain and the need for sustainable techniques with low carbon impact becomes more evident. Hard to see how these requirements can be achieved under likely circumstances.davehttps://www.blogger.com/profile/05472098969204011008noreply@blogger.com
