Sydney Average Temperature vs US Annual CO₂ Emissions
Sydney Average Temperature and US Annual CO₂ Emissions correlate at r = +0.47 over 65 years (1960–2024), p < 0.0001. With the time trend removed, r = +0.02. Interpret with caution.
Verdict: Interpret with caution. Much of the apparent link is driven by a shared time trend: r falls from 0.47 to 0.02 once the trend is removed.
