Remote Sensing Systems (RSS) has just released their satellite measured temperature anomaly data for May 2013.
Globally, May 2013 averaged .139 degrees C. or .250 degrees F. above normal in the lower troposphere, making May 2013 the 11th warmest May in the satellite record which goes back to 1979.

The warmest regions compared to normal were across Siberia and eastern Europe. Greenland was colder than normal.
The RSS image below shows the updated global temperature trend which is now at +.129 C. per decade.
Global CO2 emissions reached an all-time high in 2013, but the annual rate of increase was lower....
How did November 2014 rank in terms of global surface temperature?
Global extreme temperature anomalies are rising faster than average temperature anomalies.
People's perceptions of global warming are influenced most by their political orientation and not by actual changes in climate.
Current record-breaking sea surface temperatures indicate that the 14-year pause in ocean warming has ended, according to a new study.
Will 2014 end up as the warmest year on record?
