Arctic Sea Ice Extent (September) vs US Annual CO₂ Emissions
Arctic Sea Ice Extent (September) and US Annual CO₂ Emissions correlate at r = -0.31 over 46 years (1979–2024), p = 0.038. With the time trend removed, r = +0.08. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.038) and the association survives trend removal (detrended r = 0.08). Correlation still isn't causation, but this one isn't an obvious artifact.
