thinkprogress.org/climate/2014/01/21/3187581/noaa-nasa-2013-temperature/While Americans deal with a wintery January and try to understand what a polar vortex is, one thing is clear: 2013 was one of the ten hottest years since records began in 1880. For the 37th consecutive year, global temperatures were higher than average. The National Oceanic and Atmospheric Administration (NOAA) reported Tuesday that 2013 was tied with 2003 as the fourth-warmest year since records began in 1880 — annual land and ocean surface temperatures were 0.62°C (1.12°F) higher than average. The National Aeronautics and Space Administration (NASA) reported that along with 2009 and 2006, 2013 was tied for the seventh-warmest year on record, “continuing a long-term trend of rising global temperatures.” NASA used essentially the same data — it just processes it slightly differently than NOAA does. Indeed, the difference between 4th place and 7th place is just two-hundredths of a degree. NASA had the “temperature anomaly” — how much the global temperature deviated from the average — pegged at 0.60°C and NOAA had 0.58°C.
