Arctic Sea Ice Extent (September) vs US CO₂ Emissions per Capita
Arctic Sea Ice Extent (September) and US CO₂ Emissions per Capita correlate at r = +0.67 over 46 years (1979–2024), p < 0.0001. With the time trend removed, r = +0.12. 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 0.12 — the relationship is probably coincidental, not causal.
