World’s 76 Best Tide Gauges Show ‘Negligible’ Sea Level Rise A new scientific paper affirms “all the long-term-trend (LTT) tide gauges of the world consistently show a negligible acceleration since the time they started recording in the late 1800s/early 1900s” and there is “no sign of climate models predicted sharply warming and accelerating sea level rise.” An accurate determination of sea level rise acceleration trends requires at least 100 years of data due to the natural (60- to 80-year) oscillations that could bias the results depending on the start and end dates. There are 88 world tide gauges with a record length of at least 100 years in the psmsl.org database. Of those, 76 have no data quality issues. The average rate of sea level rise for these 76 global-scale tide gauges is just 0.337 millimeters per year (mm/yr), and the acceleration is a “negligible” 0.007 mm/yr². Thus, the average rate of sea level rise for the world’s best long-term-trend (LTT) tide gauges amounts to about 3½ centimeters per century. Further, the relatively high (2 to 3 mm/yr) local rates of sea level rise in the studied region (the Mexican Caribbean) were determined to be primarily associated with land subsidence. This affirms the conclusion (Piecuch et al., 2018) that geological processes, or vertical land motions, are more influential than climate-related processes in establishing local relative sea level trends. These results once again serve to undermine the model-based claims that the world’s seas are sharply rising and accelerating due to CO2-induced global warming. principia-scientific.org
