US Annual CO₂ Emissions vs US Exports

US Annual CO₂ Emissions and US Exports correlate at r = +0.62 over 55 years (1970–2024), p < 0.0001. With the time trend removed, r = +0.32. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.32). Correlation still isn't causation, but this one isn't an obvious artifact.
