Global Temperature Anomaly vs US Egg Consumption per Person

Global Temperature Anomaly and US Egg Consumption per Person correlate at r = -0.47 over 63 years (1961–2023), p = 1.2e-4. With the time trend removed, r = +0.41. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.47, but once each series' time trend is removed it becomes 0.41. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.

Pearson r: -0.47
p-value: 1.2e-4
Years compared (n): 63 (1961–2023)
95% confidence interval: -0.64 to -0.25
Correlation with the time trend removed: +0.41
