Atmospheric CO₂ (Mauna Loa) vs US Renewable Energy Share
Atmospheric CO₂ (Mauna Loa) and US Renewable Energy Share correlate at r = +0.92 over 61 years (1965–2025), p < 0.0001. With the time trend removed, r = +0.90. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.90). Correlation still isn't causation, but this one isn't an obvious artifact.
