2018 was 6th Warmest Year Globally of Last 40 Years
The Version 6.0 global average lower tropospheric temperature (LT) anomaly for December, 2018 was +0.25 deg. C, down a little from +0.28 deg. C in November:
Various regional LT departures from the 30-year (1981-2010) average for the last 24 months are:
The 2018 globally averaged temperature anomaly, adjusted for the number of days in each month, is +0.23 deg. C, making 2018 the 6th warmest year in the now-40 year satellite record of global lower tropospheric temperature variations.
The linear temperature trend of the global average lower tropospheric temperature anomalies from January 1979 through December 2018 remains at +0.13 C/decade.
The UAH LT global anomaly image for December, 2018 should be available in the next few days here.
The new Version 6 files should also be updated at that time, and are located here:
