Sydney Average Temperature vs US Adult Obesity

Sydney Average Temperature and US Adult Obesity correlate at r = +0.51 over 45 years (1980–2024), p = 3.2e-4. With the time trend removed, r = +0.30. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 3.2e-4) and the association survives trend removal (detrended r = 0.30). Correlation still isn't causation, but this one isn't an obvious artifact.
