Tokyo Average Temperature vs US CO₂ Emissions per Capita
Tokyo Average Temperature and US CO₂ Emissions per Capita correlate at r = -0.66 over 55 years (1970–2024), p < 0.0001. With the time trend removed, r = +0.01. 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 0.01 — the relationship is probably coincidental, not causal.
