Global Temperature Anomaly vs US Population
Global Temperature Anomaly and US Population correlate at r = +0.95 over 66 years (1960–2025), p < 0.0001. With the time trend removed, r = +0.06. 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 0.06 — the relationship is probably coincidental, not causal.
