Latest Global Temp. Anomaly (September '18: +0.14°C)
UAH Global Temperature Update for September, 2018: +0.14 deg. C

October 2nd, 2018
Globally, the coolest September in the last 10 years.
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for September, 2018 was +0.14 deg. C, down a little from +0.19 deg. C in August:

Global area-averaged lower tropospheric temperature anomalies (departures from 30-year calendar monthly means, 1981-2010). The 13-month centered average is meant to give an indication of the lower frequency variations in the data; the choice of 13 months is somewhat arbitrary… an odd number of months allows centered plotting on months with no time lag between the two plotted time series. The inclusion of two of the same calendar months on the ends of the 13 month averaging period causes no issues with interpretation because the seasonal temperature cycle has been removed, and so has the distinction between calendar months.
This was the coolest September in the last 10 years in the global average.
Some regional LT departures from the 30-year (1981-2010) average for the last 21 months are:

Spencer isn't drawing the same conclusions as Blot all he's doing is reporting the data, it's never been about a single month or any one years temperature and you know that. In fact most conservatives understand this i'm sure.

Have a look at 2012 which dipped under the average by 0.2 then the following year was 3rd hottest on record .48 above the average. When your trend is cooling for 30 years then you may have a valid argument until then it's getting hotter.
