Without sea-level acceleration, the 20th-century sea-level trend of 1.7 mm/y would produce a rise of only approximately 0.15 m from 2010 to 2100; therefore, sea-level acceleration is a critical component of projected sea-level rise. To determine this acceleration, we analyze monthly-averaged records for 57 U.S. tide gauges in the Permanent Service for Mean Sea Level (PSMSL) data base that have lengths of 60–156 years. Least-squares quadratic analysis of each of the 57 records are performed to quantify accelerations, and 25 gauge records having data spanning from 1930 to 2010 are analyzed.
In both cases we obtain small average sea-level decelerations.
To compare these results with worldwide data, we extend the analysis of Douglas (1992) by an additional 25 years and analyze revised data of Church and White (2006) from 1930 to 2007 and also obtain small sea-level decelerations similar to those we obtain from U.S. gauge records.

With having read the new Mann sea-level hockey stick paper in detail, I will still venture that sampling at two spatial points in N Carolina prone to shifting sands is not sufficient for making global inferences about sea levels and that there are numerous systematic uncertainties not properly accounted for. Amateur GIGO.

Some perspective:
Note the units: metre = 1000 mm.

Anyways, I'll renew my offer to buy your soon-to-be-inundated property for 1 Australian dollar.
On the other hand, to make it fair dinkum offer, I should mention that Al Gore acted on his claims of imminent future AGW flooding by purchasing a sea-side mansion in Montecito, California last year.
Never criticize anyone until you've walked several kilometres in their shoes.
Because
1. You're now several kilometres away; and
2. You've got their shoes.
