According to always trustworthy US government, sea level is rising 3.1 mm/year. As tiny as this is, it is exaggerated by more than 400% over the actual data. Of the 148 currently active (readings after 2010) NOAA global tide gauges, 83% are below the official average. The 148 stations have a mean value of 0.73 mm/year. Almost a third of the stations show no sea level rise.
As with everything else the government says about the climate, there isn’t one smidgen of truth to the sea level story.
