Climate Forecast System Reanalysis (CFSR) monthly global surface temperature anomaly estimates for 2014 through August 2016 from the University of Maine Climate Change Institute (UM CCI) and from WeatherBELL (WxBELL) are graphed below along with monthly global temperature anomaly estimates for the lower troposphere derived from satellite measurements provided by the University of Alabama at Huntsville (UAH). All three of these estimates showed a slight increase from July to August. The August UM CCI and WxBELL estimates are preliminary and may change slightly when final estimates are released.
Also shown for comparison are monthly global temperature anomaly estimates from five other major sources, including lower tropospheric estimates from Remote Sensing Systems (RSS), and surface estimates from the US National Center for Environmental Information (NCEI), US National Aeronautics and Space Administration (NASA) Goddard Institute of Space Studies (GISS), the UK Hadley Climate Research Unit Temperature version 4 (CRUT4), and the Berkeley Earth Surface Temperature (BEST), all final through July 2016. All estimates have been synced to the latest climatological reference period 1981-2010.
