US Meat Consumption per Person vs US CO₂ Emissions per Capita

US Meat Consumption per Person and US CO₂ Emissions per Capita correlate at r = -0.49 over 54 years (1970–2023), p = 1.6e-4. With the time trend removed, r = +0.69. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.49, but once each series' time trend is removed it becomes 0.69. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
