Arctic Sea Ice Extent (September) vs US Rural Population
Arctic Sea Ice Extent (September) and US Rural Population correlate at r = +0.84 over 47 years (1979–2025), p < 0.0001. With the time trend removed, r = +0.14. 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 0.14 — the relationship is probably coincidental, not causal.
