Atmospheric Methane (global) vs US Nuclear Power Generation
Atmospheric Methane (global) and US Nuclear Power Generation correlate at r = +0.78 over 42 years (1984–2025), 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.
