Sydney Average Temperature vs US Forest Area
Sydney Average Temperature and US Forest Area correlate at r = +0.49 over 34 years (1990–2023), p = 0.0029. With the time trend removed, r = +0.27. Holds up after detrending.
Verdict: Holds up after detrending. Statistically significant (p = 0.0029) and the association survives trend removal (detrended r = 0.27). Correlation still isn't causation, but this one isn't an obvious artifact.
