One of the surprising things is that the sea is not flat, but there are places where sea level is lower than others, rising faster than others or slower. Mostly bunnies just look at the averages, but the money, just as with temperature and precipitation changes is local.
Turns out that the northeast US coast, from Cape Hatteras on north up to Maine is the so called Northeast Hot Spot (NEH) and the rate of sea level rise since 1950 or so is three times the global. Sallenger Doran and Howd explore the "Hotspot of accelerated sea level rise on the Atlantic coast of North America". Turns out it's not all bad news because
In the late twentieth century, sea levels were relatively low along the North American east coast, particularly north of Cape Hatteras8,9. Sea-surface gradients sloped down towards the coast away from the Gulf Stream and its continuation to the northeast, the North Atlantic Current10. The sharp pressure gradients balance the Coriolis force to sustain these narrow and strong geostrophic currents, leading to low coastal sea levels.But the recent rate of change in this area is large. The figure to the left shows the Sea Level Rise Differences from 1970-2009 along the coast, that on the right shows the SLRD time series for start years from 1894 to 1970. The former has a length of 115 years, the latter 40 years.
