US Federal Debt Outstanding vs US CO₂ Emissions per Capita
US Federal Debt Outstanding and US CO₂ Emissions per Capita correlate at r = -0.94 over 55 years (1970–2024), p < 0.0001. With the time trend removed, r = -0.70. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = -0.70). Correlation still isn't causation, but this one isn't an obvious artifact.
