Report comes after North Carolina senate proposes bill to ban predictions of increase in rates of sea-level rise.
Research from the US Geological Survey (USGS) shows that sea levels are rising much faster between North Carolina and Massachusetts than anywhere else in the world. The news comes less than two weeks after North Carolina's Senate passed a bill banning state agencies from reporting predictions of increasing rates of sea-level rise.
Asbury Sallenger, an oceanographer at the USGS in St Petersburg, Florida, and his colleagues published their report today in Nature Climate Change1. They analysed tide-gauge records from around North America from between 1950 and 2009, and found that the rates of sea-level rise along the northern half of the eastern seaboard from Cape Hatteras, North Carolina, to Boston, Massachusetts are increasing three to four times faster than rates of sea-level rise globally.
In absolute figures, sea levels on this stretch of coast have climbed by between 2 and 3.7 millimetres per year since 1980, whereas the global increase over the same period was 0.61.0 millimetres per year.
The existence of the hotspot is consistent with the measured slowing of Atlantic Ocean circulation, which may be tied to changes in water temperature, salinity and density in the subpolar north of the ocean.
The researchers predicted that by 2100, sea levels in the hotspot would rise by between 20 and 29 centimetres above the global increase, which most oceanographers predict will be about one metre.
"Many people mistakenly think that the rate of sea-level rise is the same everywhere as glaciers and ice caps melt, said Marcia McNutt, director of the USGS. However, regional variations in temperature, water salinity and air pressure can cause rates of increase to differ considerably, as can ocean currents and land movements...

Beach erosion is caused by many things... we have beach erosion in Florida where I live... It has nothing to do with sea levels rising - my back yard ends at salt water. I watch. Tides ebb and flow but the level’s been the same for decades.
Do these fools think that there is some way to stack water locally?
Don’t try this at home, folks!
Not only that but tectonic plate motion will put the whole thing in the drink, at two +/- inches per year going that-a-way. The downside of that is that the eastern snivelers will be slowly forced west——will have to put strict border control in place at that point to keep the Kennedy clan out of my neighborhood.
As long as it is not Guam! Who was that leftist loon in Congress worried about the island capsizing?
2 millimeters! Crimney sakes, it takes 2.54 Centimeters, which to equal an inch.
I’d like to know how they measured the depth of the ocean. Did they stick their big toes in the surf and say, “The ocean is rising. The ocean is rising!”
did they measure during high tide or low tide? Did they measure during a full moon?
The earth doesn’t orbit the sun in a perfect circle, the ordit is egg shaped, and every 11,500 years, the earth is the furthest from the sun. Which accounts for the Little Ice Age and many other climate abberations.
“The researchers predicted that by 2100, sea levels in the hotspot would rise by between 20 and 29 centimetres above the global increase, which most oceanographers predict will be about one metre.”
Yeah, right and flying pigs will sing the Hallelujah Chorus while pink Unicorns play the bass.
