US Annual CO₂ Emissions vs US Egg Consumption per Person

US Annual CO₂ Emissions and US Egg Consumption per Person correlate at r = -0.78 over 63 years (1961–2023), p < 0.0001. With the time trend removed, r = -0.62. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = -0.62). Correlation still isn't causation, but this one isn't an obvious artifact.
