NOAA Report by Doyle Rice, USA Today
2010 tied with 2005 as the warmest year of the global surface temperature record, according to data released today by the National Climatic Data Center. Records began in 1880. The Earth's temperature was 1.12 degrees F above the 20th-century average, which was the same as 2005.
It was the 34th-consecutive year that the global temperature were above average, according to the data center. The last below-average year was 1976.
The global land surface temperatures for 2010 were the warmest on record at 1.8 F above the 20th-century average.
Warmer-than-average temperatures occurred for most of the world's surface. The warmest temperatures occurred throughout the high-latitude regions of the Northern Hemisphere, Canada, Alaska, the tropical Atlantic Ocean, the Middle East, Eastern Europe and northern Africa.
Nine of the Earth's 10 warmest years on record have occurred since 2001, and all 12 of the warmest years have occurred since 1997.
The satellite data shows that the globe continues to warm unevenly, with warming increasing as you go north: The Arctic Ocean has warmed an average of almost 3 degrees in the past 32 years.
