Global Temperature Anomaly vs US Annual Working Hours per Worker

Global Temperature Anomaly and US Annual Working Hours per Worker correlate at r = -0.56 over 81 years (1870–2023), p < 0.0001. With the time trend removed, r = +0.67. Direction flips without the trend.

Verdict: Direction flips without the trend. The raw correlation is -0.56, but once each series' time trend is removed it becomes 0.67. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.

Pearson r: -0.56
p-value: < 0.0001
Years compared (n): 81 (1870–2023)
95% confidence interval: -0.69 to -0.39
Correlation with the time trend removed: +0.67
