Atmospheric CO₂ (Mauna Loa) vs US Coal Consumption
Atmospheric CO₂ (Mauna Loa) and US Coal Consumption correlate at r = -0.00 over 61 years (1965–2025), p = 0.975. With the time trend removed, r = -0.92. Not statistically significant.
Verdict: Not statistically significant. With n = 61, this correlation isn't statistically significant (p = 0.975). It could easily be chance.
