Sydney Average Temperature vs Atmospheric Methane (global)
Sydney Average Temperature and Atmospheric Methane (global) correlate at r = +0.56 over 42 years (1984–2025), p = 1.2e-4. With the time trend removed, r = -0.22. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 1.2e-4) and the association survives trend removal (detrended r = -0.22). Correlation still isn't causation, but this one isn't an obvious artifact.
