Combined global land and ocean surface temperatures were 1.12° F above the 20th Century average of 57° F. According to NOAA, 1998 was the third warmest year on record. Temperatures records date back to 1880.
The Northern Hemisphere was 1.31° F above the 20th century average. The Southern Hemisphere was 0.92° F above the 20th Century average.
Temperatures in 2010 were higher than the 20th century average for the 34th year in a row, NOAA said. Overall 2010 and 2005 were 1.12°F above the century average in terms of combined land and water surface temperatures across the world.
"This warmth reinforces the notion that we are exceeding the climate change," says David Easterling, chief of scientific services at NOAA’s National Climate Data Center," USA Today reported.
However, other experts disagree that this most recent data is further proof of global warming. A climatologist with the Cato Institute in Washington, Pat Michaels, said, "If you draw a trend line from the data, it's pretty flat from the 1990s. We don't see much of a warming trend over the past 12 years."
