Tokyo Average Temperature vs US Life Expectancy
Tokyo Average Temperature and US Life Expectancy correlate at r = +0.61 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = -0.39. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.61, but once each series' time trend is removed it becomes -0.39. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
