Number one *scientific* priority in climate science is to figure out what causes El Nino.

#1 *technical* priority is to guide transition to alternative energy.

#1 wild goose chase is to sequester CO2

Peak Oil Barrel – The Reported Death of Peak Oil Has Been Greatly Exaggerated

Peak oil people have become more analytical now and they don't follow the old school pure narratives of the Kunstler-types. They want the numbers to add up -- for example check the peakoilbarrel.com blog, which is almost all projections. Kunstler is not mathematically inclined

Hoyer Metric in LTE Model Fitting Modern signal processing and system identification frequently require quantifying the sparseness or "peakiness" of vectors—such as power spectra. The Hoyer metric, introduced by Hoyer , is a widely adopted measure for this purpose, especially in the context of nonnegative data (like spectra). This blog post explains the Hoyer metric's role in fitting models in the context of LTE, its mathematical form, and provides references to its origins.

The mystery of El Nino Google Gemini makes predictions on the next El Nino when prompted -- scroll to the end. There has ALWAYS been stratification in the ocean via the primary thermocline. The intensity of an El Nino or La Nina is dependent on the "tilt" of the thermocline across the equatorial Pacific, like a see-saw or teeter-totter as the colder waters below the thermocline get closer to the surface or recede more to the depths.

Current status of research according to AI explain the Pukite tidal theory The Pukite Tidal Theory, primarily developed by researcher Paul Pukite, proposes that long-period tidal forcing is the underlying driver for several major geophysical and atmospheric cycles that have previously been considered erratic or unresolved. The core of the theory is that small gravitational perturbations from the Moon and Sun, which are perfectly predictable, are "aliased" or modulated by seasonal cycles to create the complex behaviors seen in Earth's systems.

Remember that USA consumes 20 million barrels of oil per day but only extracts 13 million of crude per day from its territory.
Still a huge dependence on imported oil despite the claims of politicians such as Trump. Keeping the public ignorant.

Claude Code Oil Shock Model This took me all of a few minutes with Claude Code, given this prompt: create a convolution-based algorithm of the Oil Shock Model described in Mathematical GeoEnergy (Wiley, 2019). Add a pltting routine and keep hooks for parameterizing and comparing against empirical oil data. This the result, running from the command line: Fitting OSM to synthetic data … k_fallow=0.2482 k_build=0.2463 k_maturation=0.0599 cost = 7.8022…

LLM logrolling in our time To preface this post, there was at one time a regular column in the long-defunct humor magazine Spy called "Logrolling In Our Time". The column exposed reciprocal favor-trading in literary media where authors and critics provided mutual, suspicious endorsements.

Spectral details in Chandler Wobble and QBO Using LLMs as peer-review devil's advocates for research findings can't hurt and can only help strengthen an argument. One of the common criticisms an LLM makes is that it will claim that a factor is "too weak" or insignificant to serve as a mechanism for some observed behavior. This has almost turned into a cliche since it caters to the consensus bias of "

Peer review of peer review Prompted Claude with this: This is a submitted contribution to ESD Ideas, a journal committed to presenting innovative ideas in geophysics, relayed in short form of a couple of pages. Provide a peer-review based on what value it may provide for future research. (note that short form demanded citation to fuller derivation found in Mathematical Geoenergy (2019)) Now let me fetch the actual PDF preprint and the referee comments to give a thorough review.

Not going to make that much of a difference. All that does is change the frequency response. The forced response is likely the primary signal and the rest is an amplitude/phase filter.

Pairing of solar and lunar factors A number of the Earth's geophysical behaviors characterized by cycles have both a solar and lunar basis. For the ubiquitous ocean tides, the magnitude of each factor are roughly the same -- rationalized by the fact that even though the sun is much more massive than the moon, it's much further away. However, there are several behaviors that even though they have a clear solar forcing, lack a lunar counterpart.

The perplexing Chandler wobble I had heard that Perplexity was an LLM geared to scientific research, so I gave it this prompt: Explain the Chandler wobble as due to a stroboscopic driving force emerging from the nonlinear modulation of an impulsed annual signal with the periodic declination torque of the lunar draconic cycle operating as a wavenumber=0 group symmetry. The Chandler wobble can be viewed as a stroboscopically forced precession mode of Earth’s rotation, driven by a nonlinear interaction between an annually pulsed excitation and the lunar draconic (nodal) tide, with the effective forcing emerging in the band of the 433‑day free wobble.

Every time series featuring a measure related to sea-level or thermocline level has a striking relationship to long-period tidal cycles. Shouldn't be a surprise as no other equivalent forces available, yet the difficulty on doing nonlinear analysis has thwarted progress
