Atmospheric Methane (global) vs US Air Passengers Carried
Atmospheric Methane (global) and US Air Passengers Carried correlate at r = +0.80 over 40 years (1984–2023), p < 0.0001. With the time trend removed, r = -0.09. 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 -0.09 — the relationship is probably coincidental, not causal.
