Tokyo Average Temperature vs US Inflation Rate

Tokyo Average Temperature and US Inflation Rate correlate at r = -0.29 over 65 years (1960–2024), p = 0.021. With the time trend removed, r = -0.14. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 0.021) and the association survives trend removal (detrended r = -0.14). Correlation still isn't causation, but this one isn't an obvious artifact.
