US Air Passengers Carried vs US CO₂ Emissions per Capita
US Air Passengers Carried and US CO₂ Emissions per Capita correlate at r = -0.74 over 54 years (1970–2023), p < 0.0001. With the time trend removed, r = +0.47. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.74, but once each series' time trend is removed it becomes 0.47. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
