Atmospheric CO₂ (Mauna Loa) vs US Milk Consumption per Person
Atmospheric CO₂ (Mauna Loa) and US Milk Consumption per Person correlate at r = -0.54 over 63 years (1961–2023), p < 0.0001. With the time trend removed, r = -0.38. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = -0.38). Correlation still isn't causation, but this one isn't an obvious artifact.
