This is a NOAA webpage which has looked at increments of 50 year sea level trends at many sites across the US. (and worldwide sites if you click around a little)

Click on the tab that says, “Variation of 50-Year Relative Sea Level Trends” you can look at different gauges around the country for different 50 year averages.
If you look at the trends in the New England locations it has actually varied below average and drifted back to baseline. It’s all BS!
Do you know how many tons of ice have to melt to raise the sea level 1 mm? 1 ton? 100 tons? 1,000,000 tons? 100,000,000? 1,000,000,000? Well if you said none, you are right. It takes 360,000,000 tons of melted ice to raise the sea level 1 mm.
