Tokyo Average Temperature vs US Homicide Rate
Tokyo Average Temperature and US Homicide Rate correlate at r = -0.41 over 31 years (1990–2023), p = 0.023. With the time trend removed, r = +0.23. 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 0.23 — the relationship is probably coincidental, not causal.
