Atmospheric CO₂ (Mauna Loa) vs US Agriculture Value Added
Atmospheric CO₂ (Mauna Loa) and US Agriculture Value Added correlate at r = -0.63 over 25 years (1997–2021), p = 6.8e-4. With the time trend removed, r = -0.26. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 6.8e-4) and the association survives trend removal (detrended r = -0.26). Correlation still isn't causation, but this one isn't an obvious artifact.
