Atmospheric CO₂ (Mauna Loa) vs US Death Rate
Atmospheric CO₂ (Mauna Loa) and US Death Rate correlate at r = -0.30 over 65 years (1960–2024), p = 0.014. With the time trend removed, r = +0.67. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.30, 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.
