The above UAH chart shows the monthly deviations from the mean (blue line) of the global temperatures of the lower troposphere at 1500 meters altitude (TLT) and the 13-month running average (red curve). Due to a powerful globally time-shifted El Niño event beginning in the summer of 2015, there was a record string of months from November to March. There was a strong retreat from April to June, with temperatures stagnant near 0.44°K over the past 3 months. Source: UAH Global Temperature Update for September 2016: +0.44°CC.
