2010 tied 2005 as the warmest year on record, according to separate analyses by NASA and National Oceanic and Atmospheric Administration (NOAA).
"If the warming trend continues, as is expected, if greenhouse gases continue to increase, the 2010 record will not stand for long," said James Hansen, the director of NASA's Goddard Institute for Space Studies (GISS), in a statement.
The global land surface temperatures for 2010 tied for the second warmest on record, while global ocean surface temperatures for 2010 tied with 2005 as the third warmest on record, according to the NOAA.

"The record temperature in 2010 is particularly noteworthy, because the last half of the year was marked by a transition to strong La Niña conditions, which bring cool sea surface temperatures to the eastern tropical Pacific Ocean," stated a release from GISS.
GISS says the warmest years since recording-keeping began in 1880 are 2005 and 2010 (tied), followed by 1998, 2002, 2003, 2006, 2007 and 2009.
2010 was also the wettest year on record in terms of precipitation, according to the Global Historical Climatology Network.
Temperatures in the United States were more moderate, but were still above the long-term average. Temperatures were most above normal in the upper Midwest and Northeast. Temperatures were below normal in Florida, Georgia, Mississippi, and Alabama.
