US Marriage Rate vs US CO₂ Emissions per Capita
US Marriage Rate and US CO₂ Emissions per Capita correlate at r = +0.84 over 52 years (1970–2022), 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.
