US Annual CO₂ Emissions vs US Resident Patent Applications
US Annual CO₂ Emissions and US Resident Patent Applications correlate at r = +0.49 over 42 years (1980–2021), p = 9.3e-4. With the time trend removed, r = +0.05. Interpret with caution.
Verdict: Interpret with caution. Much of the apparent link is driven by a shared time trend: r falls from 0.49 to 0.05 once the trend is removed.
