Global Temperature June 2017 Preliminary

Climate Forecast System Reanalysis (CFSR) monthly global surface temperature anomaly estimates for 2014 through June 2017 from the University of Maine Climate Change Institute (UM CCI) and from WeatherBELL (WxBELL) are graphed below. The UM CCI CFSR estimates have been adjusted (UM adj), while the WxBELL CFSR estimates have been left unadjusted to show the difference. Both of these estimates decreased from May to June in 2017. The UM CCI CFSR adjusted monthly estimate for June 2017 is based on preliminary daily averages, and thus may change slightly when the final monthly estimate is released.

Also shown for comparison are monthly global temperature anomaly estimates from seven other major sources, including lower tropospheric estimates from the University of Alabama at Huntsville (UAH) and Remote Sensing Systems (RSS), and surface estimates from the European Centre for Medium-Range Weather Forecast (ECMWF) Reanalysis Interim adjusted (ERAI adj), 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 May 2017. All estimates have been shifted to the latest standard climatological reference period 1981-2010 to provide a consistent baseline.

Update 2017 July 5

Final June 2017 global temperature anomaly estimates from UAH, RSS, and ERAI adj have been added to the graph and the UM CCI June estimate has been updated based on final daily estimates.
