Atmospheric CO₂ (Mauna Loa) vs US Energy Use per Capita
Atmospheric CO₂ (Mauna Loa) and US Energy Use per Capita correlate at r = -0.44 over 61 years (1965–2025), p = 4.3e-4. With the time trend removed, r = -0.77. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 4.3e-4) and the association survives trend removal (detrended r = -0.77). Correlation still isn't causation, but this one isn't an obvious artifact.
