According to NOAA and NASA, 2014 was the warmest year on record. A new report names 2014 as the warmest year since records were first kept in 1880.
Across all land and ocean surfaces, the average temperature was up 1.24 degrees Fahrenheit over the 20th century average, according to numbers released by the National Oceanic and Atmospheric Administration (NOAA). That caused 2014 to pass the previous record-holders: 2005 and 2010. The warmest December since 1880 helped push 2014 into record territory. The same conclusion was reached by NASA, who also called 2014 the warmest year on record in a separate analysis released on Friday.
