UAH: 5th Warmest September

UAH has posted their global surface temperature anomaly for last month: +0.29 C.


That sounds low, but actually it's the 5th highest September in their records. (I'm still unsure if one can compare a month's value to any other month in the entire record, or only to the same month in different years.) Remember, they recently moved their baseline forward. And we just started a new La Nina.

It's telling that months that now seem unremarkable are in fact quite high compared to the entire record. We really are in a new normal.
