US Annual CO₂ Emissions vs US Adolescent Birth Rate
US Annual CO₂ Emissions and US Adolescent Birth Rate correlate at r = -0.63 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = +0.40. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.63, but once each series' time trend is removed it becomes 0.40. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
