Don’t Sell Your Beachfront Property Yet

In spite of all the alarm being forced upon those living near the coast as a result of Local Authorities drawing scary lines on their LIM reports, it seems that doomsday is a little way off yet.

We can postpone the coastal climate emergency for a week or two.

A diligent researcher has pulled the data from the most reliable tide gauges around the world and found 76 that have a data record longer than 100 years and no quality issues. He even found one in Dunedin.

His conclusion: “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 data base. Of those, 76 have no data quality issues.

The average rate of 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. […]

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. […]

The Dunedin data is 1.325 mm/year rise since 1900 and accelerating at an alarming 0.01775 mm/yr2. A bit above the average but not time to list your beachfront property with the real estate agent just yet.
