Tokyo Average Temperature vs US Internet Usage
Tokyo Average Temperature and US Internet Usage correlate at r = +0.64 over 35 years (1990–2024), p < 0.0001. With the time trend removed, r = -0.18. 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 -0.18 — the relationship is probably coincidental, not causal.
