As a complement to my post Rise of sea levels is ‘the greatest lie ever told’ here are some long term graphs of sea level trends from NOAA.
I start with 3 islands (Hawaii, American Samoa and Magueyes Island) which should be most threatened according to this ”sea rise” scare.
First from Honolulu in beautiful Hawaii: Data from 1905
The plot shows the monthly mean sea level with the average seasonal cycle and the linear trend removed (thin line) and the 5-month average (thick line). The interannual variation is caused by irregular fluctuations in coastal ocean temperatures, salinities, winds, atmospheric pressures, and ocean currents. The interannual variation for most Pacific stations is closely related to the El Niño/Southern Oscillation.
From Honolulu, Hawaii: Data from 1980

And then from Pago Pago, American Samoa: Data from 1980
And then Magueyes Island, Puerto Rico: Data from 1980
And What about Skagway, Alaska: Data from 1945
The mean sea level trend is -17.12 millimeters/year with a 95% confidence interval of +/- 0.65 mm/yr based on monthly mean sea level data from 1944 to 2006 which is equivalent to a change of -5.62 feet in 100 years.
And then from Stockholm in Sweden: Data from 1889
The mean sea level trend is -3.94 millimeters/year with a 95% confidence interval of +/- 0.35 mm/yr based on monthly mean sea level data from 1889 to 2003 which is equivalent to a change of -1.29 feet in 100 years
