The long-term trend of rising global temperatures continued last year, according to NASA.

Scientists at the space agency found that global average temperatures in 2013 were tied with 2009 and 2006 as the seventh warmest on record.

The agency said that apart from 1998, the ten warmest years since 1880 have all been recorded over the past 14 years, with 2010 and 2005 the warmest on record.

The ongoing global surface temperature measurements were made by NASA's New York based Goddard Institute for Space Studies (GISS).

Average temperatures last year were 14.6C, which is 0.6C warmer than the baseline of the middle of the 20th century. Overall, average global temperatures have risen 0.8C since 1880, the data shows.

NASA scientists said while weather patterns cause fluctuations in temperature from year to year, 2013 adds to the evidence of ongoing climate change and a long term trend towards global warming, caused by greenhouse gas levels.

The GISS data is compiled from weather information from more than 1,000 meteorological stations around the world, satellite observations of sea-surface temperature, and Antarctic research station measurements.
