Tokyo Average Temperature vs US Cereal Yield
Tokyo Average Temperature and US Cereal Yield correlate at r = +0.77 over 64 years (1961–2024), p < 0.0001. With the time trend removed, r = +0.42. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.42). Correlation still isn't causation, but this one isn't an obvious artifact.
