New York Average Temperature vs US Cereal Yield
New York Average Temperature and US Cereal Yield correlate at r = +0.66 over 64 years (1961–2024), p < 0.0001. With the time trend removed, r = -0.19. Likely spurious (shared time trend).
Verdict: Likely spurious (shared time trend). Both series mostly just trend over time. After removing that trend the correlation collapses to -0.19 — the relationship is probably coincidental, not causal.
