Tokyo Average Temperature vs US College Enrollment
Tokyo Average Temperature and US College Enrollment correlate at r = +0.64 over 39 years (1971–2022), p < 0.0001. With the time trend removed, r = -0.16. 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 -0.16 — the relationship is probably coincidental, not causal.
