Tokyo Average Temperature vs US Air Passengers Carried
Tokyo Average Temperature and US Air Passengers Carried correlate at r = +0.70 over 54 years (1970–2023), p < 0.0001. With the time trend removed, r = +0.02. 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 0.02 — the relationship is probably coincidental, not causal.
