US Internet Usage vs US CO₂ Emissions per Capita
US Internet Usage and US CO₂ Emissions per Capita correlate at r = -0.76 over 35 years (1990–2024), p < 0.0001. With the time trend removed, r = +0.80. Direction flips without the trend.
Verdict: Direction flips without the trend. The raw correlation is -0.76, but once each series' time trend is removed it becomes 0.80. The year-to-year movements run the opposite way to the long-run trends, so the headline number is misleading.
