Atmospheric Methane (global) vs US Homicide Rate
Atmospheric Methane (global) and US Homicide Rate correlate at r = -0.56 over 31 years (1990–2023), p = 0.0012. With the time trend removed, r = +0.65. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.56, 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.
