Global Temperature Anomaly vs US CO₂ Emissions per Capita
Global Temperature Anomaly and US CO₂ Emissions per Capita correlate at r = -0.88 over 55 years (1970–2024), p < 0.0001. With the time trend removed, r = -0.24. 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 -0.24 — the relationship is probably coincidental, not causal.
