We have now entered the 4th decade of measuring sea level rise using the quartet of satellites Topex and Jason 1, 2 and 3. The first 3 decades were reported in the trio of papers (Ref 1), (Ref 2) and (Ref 3). These concluded that.
1. The perceived “accelerations” are mathematical accelerations occurring due to the methods of calculation, i.e. quadratic curve fitting, as used by Nerem et al [.pdf] (Ref 4) in their 2018 paper. Also, the start date of Jan 1993 also plays a major role in how the “accelerations” pan out.
2. The “accelerations” are now generally reducing year on year and are predicted to reach levels compatible with the long term (over 100 years) Tidal Gauge values during the next decade or two before stabilising over the next few decades.
3. A time span of 30 years is much too short a period to calculate actual accelerations with 3 or more times this period being needed.
