The issue is that ENSO has a 3 to 7 yr period so that statistical significance in predicting a pattern will take several decades. What absolutely needs to be done 1st is acknowledgement of cross-validation on these 100+ sites. That will guarantee that the model WILL NOT BE FORGOTTEN in the future

It's a principle thing. All of the breakthroughs in AI and pattern recognition have been via cross-validation. Stupid to waste time waiting for predictions to pan out over decades, while competitors march on. Not my problem that climate scientists are ignorant about validation techniques.

Regarding Navier-Stokes, I developed a fluid dynamics model for solving climate science models such as ENSO (fluid) and gases (QBO). These are extremely challenging problems that climate scientists are spending much effort on but are unable to make progress and achieve little consensus. I published the complete model in late 2018 with peer-review arranged by the Wiley editor, so no AI or LLMs were involved in the process. When Sabine said that the LLM stated that the

I have 100 other sea-level sites that I've fitted (of >100yr spans), with the vast majority showing promising cross-validation intervals, all with the same set of tidal factors, varying only in amplitude and phase. This is overwhelming evidence, much stronger than a predictive match.

Lunar cycles impact El Nino events deterministically. Lunar events can impact seismic activity stochastically -- which means it is difficult to use as a prediction tool. So EL Nino impacting seismic is stochastically (probabilistically) plausible.

I place all my money into tidal forces synchronizing the resultant signal profile, much like tidal forces control the signal profile of ocean tides. imageshack.com/a/mLK17/1

The only question is what causes the magnitude and sign in the strength of the "overturning" signal (I put quotes around overturning because its likely not the same process as fresh-water lake overturning but perhaps analogous).

Every climate index, from ENSO to obscure indices such as the PNA, will reveal this characteristic. It's also a known property of nonlinear fluid dynamics at all scales, capable of being reproduced in the lab -- see geoenergymath.com/2020/05/17/d....

Indeed! Happens once a year -- a metastable condition of the ocean thermocline. Signal processing of time-series clearly shows it as a mirror reflection about the 0,5/year value in the frequency spectrum.

Yes,did see peak oil mentioned in geology textbooks in that time frame of 1980s

All these climate index curves were fitted and cross-validated using multiple linear regression (MLR), each in under a second of compute time. No need for symbolic regression or dedicated rigs here imageshack.com/a/mLK17/1
