Tree Ring Width — Long-Baseline Paleoclimate Proxy Analysis (1841–2013)

This dataset is part of the Bicameral Solar Engine project, a multi-scalar deterministic framework that maps the relationship between solar harmonic cycles and terrestrial systems including climate, economics, and biological populations. All datasets share a common methodology: raw signals are detrended using an 11-year centered moving average, normalized into Z-scores. Applies the BSE solar harmonic framework to the ITRDB Northern Hemisphere tree ring width composite (1841–2012), treating ring width as a high-noise downstream biological integrator. Achieves 93.8% T(t) phase alignment and 93.8% transition alignment despite below-significance annual correlation — exactly the signature expected of a proxy where solar phase modulates background stress conditions rather than driving annual growth directly. The shared Period 8 miss (1995–2005) appears simultaneously across five independent proxy systems, constituting evidence of real gear interference geometry rather than noise.
