Global Temperature Anomaly vs US Air Passengers Carried
Global Temperature Anomaly and US Air Passengers Carried correlate at r = +0.88 over 54 years (1970–2023), p < 0.0001. With the time trend removed, r = -0.08. 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 -0.08 — the relationship is probably coincidental, not causal.
