Tokyo Average Temperature vs US Annual CO₂ Emissions
Tokyo Average Temperature and US Annual CO₂ Emissions correlate at r = +0.39 over 65 years (1960–2024), p = 0.0013. With the time trend removed, r = -0.32. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.39, but once each series' time trend is removed it becomes -0.32. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
