NASA Research - 2010 Tied for Warmest Year on Record
January 12, 2011
Global surface temperatures in 2010 tied 2005 as the warmest on record, according to an analysis released Wednesday by researchers at NASA's Goddard Institute for Space Studies (GISS) in New York.
The two years differed by less than 0.018 degrees Fahrenheit. The difference is smaller than the uncertainty in comparing the temperatures of recent years, putting them into a statistical tie. In the new analysis, the next warmest years are 1998, 2002, 2003, 2006, 2007 and 2009, which are statistically tied for third warmest year. The GISS records begin in 1880.

NASA: 2010 Meteorological Year Warmest Ever
The 2010 meteorological year, which ended on 30 November, was the warmest in NASA's 130-year record, data posted by the agency today shows. Over the oceans as well as on land, the average global temperature for the 12-month period that began last December was 14.65˚C. That's 0.65˚C warmer than the average global temperature between 1951 and 1980, a period scientists use as a basis for comparison...
In 2010, temperatures measured over land alone were also the warmest ever, with instruments showing a December-November average of 14.85˚C. Combining this warming with above-average ocean temperatures led to the global average of 14.65˚C...
The record temperatures occurred despite a moderate occurrence of La Niña, a phenomenon over the Pacific Ocean that tends to lead to cooler temperatures at the surface, affecting the global mean.
