Atmospheric Methane (global) vs US College Enrollment
Atmospheric Methane (global) and US College Enrollment correlate at r = +0.86 over 26 years (1984–2022), p < 0.0001. With the time trend removed, r = +0.14. 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 0.14 — the relationship is probably coincidental, not causal.
