Tokyo Average Temperature vs US Exports
Tokyo Average Temperature and US Exports correlate at r = +0.55 over 55 years (1970–2024), p < 0.0001. With the time trend removed, r = -0.24. 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 -0.24 — the relationship is probably coincidental, not causal.
