London Average Temperature vs Atmospheric Methane (global)
London Average Temperature and Atmospheric Methane (global) correlate at r = +0.70 over 42 years (1984–2025), p < 0.0001. With the time trend removed, r = +0.43. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.43). Correlation still isn't causation, but this one isn't an obvious artifact.
