This visualization shows how global temperatures have risen from 1950 through the end of 2013.
NASA scientists say 2013 tied for the seventh warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the 10 warmest years in the 133-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.
NASA's Goddard Institute for Space Studies (GISS) in New York, which analyzes global surface temperatures on an ongoing basis, released an updated report Tuesday, Jan. 21, on temperatures around the globe in 2013. The comparison shows how Earth continues to experience warmer temperatures than several decades ago.
The visualization shows a running five-year average global temperature, as compared to a baseline average global temperature from 1951-1980.
