Atmospheric CO₂ (Mauna Loa) vs US Tax Revenue
Atmospheric CO₂ (Mauna Loa) and US Tax Revenue correlate at r = -0.28 over 53 years (1972–2024), p = 0.046. With the time trend removed, r = +0.20. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.046) and the association survives trend removal (detrended r = 0.20). Correlation still isn't causation, but this one isn't an obvious artifact.
