US Dollar to Japanese Yen vs Global Temperature Anomaly

US Dollar to Japanese Yen and Global Temperature Anomaly correlate at r = +0.54 over 27 years (1999–2025), p = 0.0035. With the time trend removed, r = +0.58. Holds up after detrending.

Verdict: Holds up after detrending. Statistically significant (p = 0.0035) and the association survives trend removal (detrended r = 0.58). Correlation still isn't causation, but this one isn't an obvious artifact.
