Sydney Average Temperature vs Tokyo Average Temperature
Sydney Average Temperature and Tokyo Average Temperature correlate at r = +0.57 over 66 years (1960–2025), p < 0.0001. With the time trend removed, r = +0.23. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.23). Correlation still isn't causation, but this one isn't an obvious artifact.
