Atmospheric CO₂ (Mauna Loa) vs US CO₂ Emissions per Capita
Atmospheric CO₂ (Mauna Loa) and US CO₂ Emissions per Capita correlate at r = -0.43 over 66 years (1959–2024), p = 3.2e-4. With the time trend removed, r = -0.88. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 3.2e-4) and the association survives trend removal (detrended r = -0.88). Correlation still isn't causation, but this one isn't an obvious artifact.
