Atmospheric Methane (global) vs US Imports
Atmospheric Methane (global) and US Imports correlate at r = +0.66 over 41 years (1984–2024), p < 0.0001. With the time trend removed, r = -0.65. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is 0.66, but once each series' time trend is removed it becomes -0.65. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
