US CO₂ Emissions per Capita vs Sunspot Number
US CO₂ Emissions per Capita and Sunspot Number correlate at r = +0.15 over 225 years (1800–2024), p = 0.028. With the time trend removed, r = +0.05. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.028) and the association survives trend removal (detrended r = 0.05). Correlation still isn't causation, but this one isn't an obvious artifact.
