2010 Equals Record For World’s Warmest Year

The year 2010 ranked as the warmest year on record, together with 2005 and 1998, according to the World Meteorological Organization.

Data received by the WMO show no statistically significant difference between global temperatures in 2010, 2005 and 1998.

In 2010, global average temperature was 0.53°C (0.95°F) above the 1961-90 mean. This value is 0.01°C (0.02°F) above the nominal temperature in 2005, and 0.02°C (0.05°F) above 1998. The difference between the three years is less than the margin of uncertainty (± 0.09°C or ± 0.16°F) in comparing the data.

These statistics are based on data sets maintained by the UK Meteorological Office Hadley Centre/Climatic Research Unit (HadCRU), the U.S. National Climatic Data Center (NCDC), and the U.S. National Aeronautics and Space Administration (NASA).

Arctic sea-ice cover in December 2010 was the lowest on record, with an average monthly extent of 12 million square kilometres, 1.35 million square kilometres below the 1979-2000 average for December. This follows the third-lowest minimum ice extent recorded in September.
