Dataset and Supplementary Materials for: A proxy-based exploratory climate decomposition using CO₂, AHR and orbital-insolation proxies

This Zenodo record contains the dataset and supplementary materials associated with the exploratory CO₂–PIO / AHR–PIO climate proxy study. The work combines: 1. simplified dynamic proxy models using CO₂ and AHR as broad anthropogenic-apparent proxies;2. an orbital-insolation proxy, named PIO/OIP, derived from orbital geometry and ephemeris-based Earth–Sun position data;3. a hemispheric analysis of UAH lower-troposphere temperature anomalies for 1979–2024;4. annual and endpoint contribution estimates for the Northern Hemisphere, Southern Hemisphere, hemispheric mean, and NH–SH contrast. CO₂ and AHR are not interpreted as isolated physical forcings. They are used as broad correlated proxies for multiple anthropogenic factors. The PIO/OIP term is interpreted as an orbital-insolation proxy, not as a complete radiative-forcing calculation. The reported percentages are diagnostic proxy-based estimates. In particular, the 2024 percentages are endpoint values relative to the 1979 reference year and evolve over time. Annual percentage curves are provided in the supplementary files.
