Atmospheric CO₂ (Mauna Loa) vs US GDP per Capita
Atmospheric CO₂ (Mauna Loa) and US GDP per Capita correlate at r = +0.99 over 66 years (1960–2025), p < 0.0001. With the time trend removed, r = +0.92. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.92). Correlation still isn't causation, but this one isn't an obvious artifact.
