Atmospheric CO₂ (Mauna Loa) vs US Unemployment Rate
Atmospheric CO₂ (Mauna Loa) and US Unemployment Rate correlate at r = -0.23 over 35 years (1991–2025), p = 0.191. With the time trend removed, r = -0.27. Not statistically significant.
Verdict: Not statistically significant. With n = 35, this correlation isn't statistically significant (p = 0.191). It could easily be chance.
