US CO₂ Emissions per Capita vs US GDP per Capita

US CO₂ Emissions per Capita and US GDP per Capita correlate at r = -0.51 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = -0.75. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = -0.75). Correlation still isn't causation, but this one isn't an obvious artifact.
