2010 was the Warmest Year on Record

Well it was at least tied with 2005 that is according to studies released by NASA (their study released for the Meteorological Year which ended November 30th says the same thing) and NOAA. According to the USA Today article covering the news:

The Earth's average temperature in 2010, as in 2005, was 58.12 degrees, which is 1.12 degrees above the 20th-century average of 57 degrees.

It was the 34th consecutive year that the global temperature was above average, according to the data center. The last below-average year was 1976
