Atmospheric Methane (global) vs US Population Aged 65+
Atmospheric Methane (global) and US Population Aged 65+ correlate at r = +0.90 over 42 years (1984–2025), p < 0.0001. With the time trend removed, r = +0.67. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = < 0.0001) and the association survives trend removal (detrended r = 0.67). Correlation still isn't causation, but this one isn't an obvious artifact.
