London Average Temperature vs US CO₂ Emissions per Capita

London Average Temperature and US CO₂ Emissions per Capita correlate at r = -0.31 over 65 years (1960–2024), p = 0.012. With the time trend removed, r = -0.07. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 0.012) and the association survives trend removal (detrended r = -0.07). Correlation still isn't causation, but this one isn't an obvious artifact.
