US CO₂ Emissions per Capita vs US College Enrollment
US CO₂ Emissions per Capita and US College Enrollment correlate at r = -0.82 over 39 years (1971–2022), p < 0.0001. With the time trend removed, r = +0.33. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.82, but once each series' time trend is removed it becomes 0.33. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
