Global Temperature Anomaly vs Atmospheric Methane (global)
Global Temperature Anomaly and Atmospheric Methane (global) correlate at r = +0.94 over 42 years (1984–2025), p < 0.0001. With the time trend removed, r = +0.33. Interpret with caution.
Verdict: Interpret with caution. Much of the apparent link is driven by a shared time trend: r falls from 0.94 to 0.33 once the trend is removed.
