Global Temperature Anomaly vs US Resident Patent Applications
Global Temperature Anomaly and US Resident Patent Applications correlate at r = +0.92 over 42 years (1980–2021), p < 0.0001. With the time trend removed, r = +0.14. Likely spurious (shared time trend).
Verdict: Likely spurious (shared time trend). Both series mostly just trend over time. After removing that trend the correlation collapses to 0.14 — the relationship is probably coincidental, not causal.
