Atmospheric Methane (global) vs US CO₂ Emissions per Capita
Atmospheric Methane (global) and US CO₂ Emissions per Capita correlate at r = -0.74 over 41 years (1984–2024), p < 0.0001. With the time trend removed, r = -0.03. 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 -0.03 — the relationship is probably coincidental, not causal.
