Yes, sea level rise is a physical reality that is impacting the New Jersey and the entire Mid-Atlantic coastline. The historical rate of sea level rise along the New Jersey coast over the past half century was 3-4 mm/yr (or 0.12 -0.16 in/yr), while predicted future rates are expected to increase to 12 mm/yr (or 0.5 in/yr). This means that by 2050 sea level rise is expected to rise by approximately 1 foot and by 2100 sea level rise is projected to rise about 3 feet along the Jersey shore. The NJFloodMapper is designed to visualize sea level rise within this range of heights.
The mean sea level trend over the past century is 3.99 millimeters/year (0.15 in/yr) which is equivalent to a change of 1.31 feet in 100 years. Graphic Credit: NOAA http://tidesandcurrents.noaa.gov/sltrends/sltrends_station.shtml
