*Redistribution is prohibited. *Climatology based upon the NCEP CFSR Reanalysis (1981-2010) 30-year average. Note the GFS analysis and NCEP CFSR reanalysis global 2-meter temperatures are slightly different with known biases over certain areas. The blue bubbles that are previous to the current forecast are the GFS deterministic forecast analysis global temperature anomalies. However, the differences when integrated over the Earth do not significantly affect the overall anomaly trend/signal. Yet, the "actual" global bias numbers may differ by about 0.1 degrees C. Be smart when you interpret all model estimate of temperature (or anything!) NCEP CFSR/CFSv2 Year to Date | Month to Date Temperature Anomaly

2009 - 2012 Global Temperature Traces | NCEP CFSR & JRA25 Reanalysis
Note on the daily reanalysis temperature anomalies: each is calculated according to its OWN model climatology based upon the years 1981-2010. It is an ongoing research question to be determined which is "correct" or most accurate. Detailed spatial examination of monthly means and how each reanalysis represents the two-meter temperature must be done before making grandiose claims about global warming/cooling.
Also, note these are global anomalies calculated according to each time of the year. Thus, a 0.5 degree anomaly C during January is a considerably greater departure from the "global temperature" than 0.5 degree C anomaly in July.
