US CO₂ Emissions per Capita vs US Coal Consumption

US CO₂ Emissions per Capita and US Coal Consumption correlate at r = +0.50 over 60 years (1965–2024), p < 0.0001. With the time trend removed, r = +0.79. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.79). Correlation still isn't causation, but this one isn't an obvious artifact.
