US CO₂ Emissions per Capita vs US Mobile Subscriptions
US CO₂ Emissions per Capita and US Mobile Subscriptions correlate at r = -0.86 over 48 years (1970–2024), p < 0.0001. With the time trend removed, r = -0.13. 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 -0.13 — the relationship is probably coincidental, not causal.
