Sydney Average Temperature vs US GDP per Capita
Sydney Average Temperature and US GDP per Capita correlate at r = +0.62 over 66 years (1960–2025), p < 0.0001. With the time trend removed, r = +0.11. Interpret with caution.
Verdict: Interpret with caution. Much of the apparent link is driven by a shared time trend: r falls from 0.62 to 0.11 once the trend is removed.
