The year 2016, with a temperature deviation of 0.94°C, is considered to be the hottest year on record. 2015 and 2017 came close in second and third respectively with temperature deviations of 0.9°C and 0.84°C respectively. 2014’s temperature deviation of 0.74°C made a constant rise in global temperatures from 2014 to 2016. Only 2017 recorded the initial fall in temperatures which had been experienced continuously from 2014, spanning through 2015 and 2016. Hope this helped.
