Atmospheric Methane (global) vs US GDP per Capita
Atmospheric Methane (global) and US GDP per Capita correlate at r = +0.98 over 42 years (1984–2025), p < 0.0001. With the time trend removed, r = +0.57. Interpret with caution.
Verdict: Interpret with caution. Much of the apparent link is driven by a shared time trend: r falls from 0.98 to 0.57 once the trend is removed.
