Satellite measurements of the temperature of the atmosphere rank 2014 as the third warmest year in the satellite record, according to the University of Alabama in Huntsville (UAH).
The global average temperature anomaly – that is, the variance to the long term average global temperature between 1981 and 2010 - for the layer of the atmosphere from the surface up to around 8km in altitude known as the lower troposphere during 2014 was 0.27[SUP]o[/SUP]C, according to UAH data.
This was just 0.01[SUP]o[/SUP]C warmer than 2005 and just a few hundredths of a degree warmer than 2013 and 2002 – such small differences as to make the 2014 result statistically indistinguishable from these other years. This suggests that the so called pause or hiatus in global warming continued through 2014, at least in the satellite record.
The 2014 average temperature anomaly also is in keeping with temperatures since late 2001, when the global average temperature rose to a level that is generally warmer than the 30-year baseline average. The most recent 13 complete calendar years, from 2002 through 2014, have averaged 0.18 C (about 0.33 degrees Fahrenheit) warmer than the 30-year baseline average, while the global temperature trend during that span was a warming trend at the rate of +0.05 C per decade — which is also statistically insignificant.
===As part of an ongoing joint project between UAHuntsville, NOAA and NASA, Christy and Dr. Roy Spencer, an ESSC principal scientist, use data gathered by advanced microwave sounding units on NOAA and NASA satellites to get accurate temperature readings for almost all regions of the Earth.
