US Dollar to British Pound vs US Forest Area
US Dollar to British Pound and US Forest Area correlate at r = +0.49 over 25 years (1999–2023), p = 0.014. With the time trend removed, r = -0.58. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.49, but once each series' time trend is removed it becomes -0.58. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
