US CO₂ Emissions per Capita vs US Adolescent Birth Rate

US CO₂ Emissions per Capita and US Adolescent Birth Rate correlate at r = +0.44 over 65 years (1960–2024), p = 2.7e-4. With the time trend removed, r = +0.30. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 2.7e-4) and the association survives trend removal (detrended r = 0.30). Correlation still isn't causation, but this one isn't an obvious artifact.
