According to NOAA scientists, 2010 tied with 2005 as the warmest year of the global surface temperature record, beginning in 1880.

This was the 34th consecutive year with global temperatures above the 20th century average. For the contiguous United States alone, the 2010 average annual temperature was above normal, resulting in the 23rd warmest year on record.

Globally from 2001 to 2010, it was nine of the 10 warmest years on record since records started being kept in 1880.

 "This continues to show the influence of greenhouse gases in connection to global warming," said NOAA's Dr. David Easterling.

Last year tied with 2005 as the wamest year on record and 2010 was also the wettest year on record globally. In the U.S. it was the 23rd warmest year and wetter than normal according,. Easterling said.

"There is definitely a problem with global warming as warned by former Vice Presdent Al Gore," Easterling said, adding, "Even though the southeast is iced up in an unusual weather event, Canada is unusually warm as is the actic for this time of year."
NOAA says in its report that in 2010 there was a dramatic shift in the El Niño-Southern Oscillation (ENSO), which influences global temperature and precipitation patterns - when a moderate-to-strong El Niño transitioned to La Niña conditions by July. At the end of November, La Niña was moderate-to-strong.

"In the contiguous United States, 2010 was the 14th consecutive year with an annual temperature above the long-term average. Since 1895, the temperature across the nation has increased at an average rate of approximately 0.12 F per decade," added NOAA's Dr. Derek "Deke" Arndt.

Accoding to the NOAA report, there were 1,302 U.S. tornadoes during 2010. "The year will rank among the 10 busiest for tornadoes since records began in 1950. An active storm pattern across the Northern Plains during the summer contributed to a state-record 104 confirmed tornadoes in Minnesota in 2010, making Minnesota the national tornado leader for the first time," the report says

Arndt said that during 2010, substantial precipitation fell in many drought-stricken regions. The U.S. footprint of drought reached its smallest extent during July when less than eight percent of the country was experiencing drought conditions. The increased precipitation and eradication of drought limited the acres burned and number of wildfires during 2010. Hawaii had near-record dryness occurring in some areas for most of the year, he said.
