Tokyo Average Temperature vs Global Temperature Anomaly
Tokyo Average Temperature and Global Temperature Anomaly correlate at r = +0.78 over 66 years (1960–2025), p < 0.0001. With the time trend removed, r = +0.45. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.45). Correlation still isn't causation, but this one isn't an obvious artifact.
