Global Temperature Anomalies: 1880 to 2012
2012 was the ninth warmest year on record, and the warmest year on record for continental US.
NASA’s analysis of Earth’s surface temperature found that 2012 ranked as the ninth-warmest year since 1880. NASA scientists at the Goddard Institute for Space Studies (GISS) compare the average global temperature each year to the average from 1951 to 1980. This 30-year period provides a baseline from which to measure the warming Earth has experienced due to increasing atmospheric levels of heat-trapping greenhouse gases.
