Global Temperature Anomaly vs US Electricity Generation

Global Temperature Anomaly and US Electricity Generation correlate at r = +0.82 over 41 years (1985–2025), p < 0.0001. With the time trend removed, r = -0.25. 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 -0.25 — the relationship is probably coincidental, not causal.
