3rd Warmest August

Amidst all this, UAH releases their calculation of August temperature anomaly: +0.325°C, which sounds low but is the 3rd warmest August in their 32+ years of record keeping. (Recall that last September they moved their baseline from 1979-1998 to 1981-2010.)

Their overall slope remains 0.13 ± 0.01 °C/decade (r² = 0.32).

Slope of last 10 years = -0.01 ± 0.05 °C/decade (r² = 0.001).

Slope of last 15 years = 0.08 ± 0.03 °C/decade (r² = 0.03).

Slope of last 20 years = 0.20 ± 0.02 °C/decade (r² = 0.28).
