Annual Global Lower Troposphere Temperature (TLT) Anomaly Update – Distant Third Warmest for 2015

As expected, annual global lower troposphere temperature (TLT) anomalies in 2015 for both the RSS and UAH datasets ranked a remote third warmest.  See Figures 1 through 3.

RSS data through December 2015 are here.  UAH data (beta 6.4) are here through November, and the December 2015 value of +0.44 deg C is from Dr. Roy Spencer’s blog post here.

Keep in mind, however, that lower troposphere temperature anomalies are expected to rise sharply in 2016 in a lagged response to the 2015/16 El Niño. See the post Evolutions of Global Surface and Lower Troposphere Temperature Anomalies in Responses to the 1997/98 and 2015/16 El Niños.

Next on the list is a post presenting meteorological annual mean (December-November) surface and lower troposphere temperature anomalies. I’m waiting for UKMO to publish their November 2015 HADCRUT4 values.

  2. Thanks, Bob.
    I have updated the UAH global temperature graph in my climate and meteorology pages, also the Tornado Climatology article.

    It seems odd for the headline to point out that in the RSS and UAH LTT products, 2015 was a ‘distant’ third, while the body of the article points out that there is a lagged response to El Niño events in all LTT products.

    Why compare, in the headline, this pre-El Niño year’s measurements to the two highest post-El Niño years, especially given that the body of the article implicitly points out why such a comparison is invalid?
