Breakthrough Exposes Volcanic Corruption of Global Temperature Data for 50 Years

A persistent assumption underlies modern global temperature reconstructions: that individual station errors, even when large, are diluted through spatial averaging and homogenization. That assumption deserves closer inspection. Recent analysis of station-level data suggests that under certain conditions—specifically when extreme outliers evade quality control and are subsequently incorporated into homogenization routines—localized anomalies can propagate nonlinearly through the global record.
The present investigation began with a routine audit of tropical station residuals within the GHCN (Global Historical Climatology Network) dataset. The initial objective was unremarkable: quantify the distribution of post-homogenization adjustments across low-latitude stations. What emerged instead was a persistent and statistically anomalous signal centered on a single station in Costa Rica, hereafter designated CR-VOLC-EL-INFIERNO-01.
The anomaly first appears in the late 1970s, coinciding with documented volcanic activity in the Talamanca Range. At face value, elevated temperatures in proximity to geothermal activity are not unexpected. What is unexpected is the magnitude, persistence, and downstream influence of those readings once introduced into the global processing pipeline.
