NASA scientists have revealed that 2013 has tied with 2009 and 2006 for the seventh warmest year since 1880, continuing a long-term trend of rising global temperatures.

With the exception of 1998, the 10 warmest years in the 134-year record have occurred since 2000, with 2010 and 2005 ranking as the warmest years on record.

NASA's report shows how Earth continues to experience temperatures warmer than those measured several decades ago.

The average temperature in 2013 was 58.3 degrees Fahrenheit (14.6 Celsius), which is 1.1 F (0.6 C) warmer than the mid-20th century baseline. The average global temperature has risen about 1.4 degrees F (0.8 C) since 1880, according to the new analysis. Exact rankings for individual years are sensitive to data inputs and analysis methods.

Scientists emphasize that weather patterns always will cause fluctuations in average temperatures from year to year, but the continued increases in greenhouse gas levels in Earth's atmosphere are driving a long-term rise in global temperatures.

The temperature analysis produced at NASA's Goddard Institute for Space Studies (GISS) is compiled from weather data from more than 1,000 meteorological stations around the world, satellite observations of sea-surface temperature, and Antarctic research station measurements, taking into account station history and urban heat island effects.
