US Annual CO₂ Emissions vs US Agriculture Value Added

US Annual CO₂ Emissions and US Agriculture Value Added correlate at r = +0.47 over 25 years (1997–2021), p = 0.018. With the time trend removed, r = -0.07. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 0.018) and the association survives trend removal (detrended r = -0.07). Correlation still isn't causation, but this one isn't an obvious artifact.
