Arctic Sea Ice Extent (September) vs US Nuclear Power Generation
Arctic Sea Ice Extent (September) and US Nuclear Power Generation correlate at r = -0.74 over 47 years (1979–2025), p < 0.0001. With the time trend removed, r = +0.10. 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 0.10 — the relationship is probably coincidental, not causal.
