Arctic Sea Ice Extent (September) vs Worldwide Major Earthquakes (M5+)
Arctic Sea Ice Extent (September) and Worldwide Major Earthquakes (M5+) correlate at r = -0.44 over 47 years (1979–2025), p = 0.0019. With the time trend removed, r = -0.31. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0019) and the association survives trend removal (detrended r = -0.31). Correlation still isn't causation, but this one isn't an obvious artifact.
