Atmospheric CO₂ (Mauna Loa) vs US Gross Savings
Atmospheric CO₂ (Mauna Loa) and US Gross Savings correlate at r = -0.68 over 55 years (1970–2024), p < 0.0001. With the time trend removed, r = +0.34. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.68, but once each series' time trend is removed it becomes 0.34. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
