World’s 76 Best Tide Gauges Show ‘Negligible’ Acceleration Of Sea Level Rise
sea ocean coast cloudsA 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.
