The average sea level rise rate for all 157 NOAA tide gauges active this century, is just below 0.7 mm/year.
The average for all 194 stations (including ones which are now defunct) is higher – at 0.8 mm/year. This indicates that sea level rise rates are slowing this century, and are much lower than the wildly bogus claims of 3.1 mm from the University of Colorado and elsewhere.
The blink comparator below shows CU claims, and the actual rates.
Eighty-eight percent of the NOAA tide gauges show sea level rise rates lower than 3.1 mm/year. This applies for both currently active tide gauges and defunct ones. Almost all of the tide gauges which show 3.1 mm/year are in subduction zones.
The widely used number of 3.1 mm/year is a complete joke.
