Worldwide Strong Earthquakes (M6+) vs US Cereal Yield
Worldwide Strong Earthquakes (M6+) and US Cereal Yield correlate at r = +0.34 over 64 years (1961–2024), p = 0.0059. With the time trend removed, r = -0.12. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0059) and the association survives trend removal (detrended r = -0.12). Correlation still isn't causation, but this one isn't an obvious artifact.
