Last Decade Was Warmest on Record, 2009 One of Warmest Years, NASA Research Finds
Jan. 22, 2010
A new analysis of global surface temperatures by NASA scientists finds the past year was tied for the second warmest since 1880.
In the Southern Hemisphere, 2009 was the warmest year on record.Although 2008 was the coolest year of the decade because of a strong La Nina that cooled the tropical Pacific Ocean, 2009 saw a return to a near-record global temperatures as the La Nina diminished, according to the new analysis by NASA's Goddard Institute for Space Studies (GISS) in New York. The past year was a small fraction of a degree cooler than 2005, the warmest on record, putting 2009 in a virtual tie with a cluster of other years --1998, 2002, 2003, 2006, and 2007 -- for the second warmest on record.
"There's always interest in the annual temperature numbers and a given year's ranking, but the ranking often misses the point," said James Hansen, GISS director.
"There's substantial year-to-year variability of global temperature caused by the tropical El Nino-La Nina cycle. When we average temperature over five or ten years to minimize that variability, we find global warming is continuing unabated."http://www.sciencedaily.com/releases/2010/01/100121170717.htmAustralia bakes through warmest decade on record

The Bureau of Meteorology says figures showing
Australia has experienced its hottest decade since records began in 1910 are clear evidence of climate change.
The Bureau's annual report has found the average temperature over the past 10 years was 0.48 degrees Celsius above average.
Climatologist David Jones says each decade since the 1940s has been warmer than the previous one.And he has warned that this year is set to be even hotter, with temperatures likely to be between 0.5 and 1 degrees above average.
"There's no doubt about global warming, the planet's been warming now for most of the last century," he said.
"Occasionally it takes a breather, during La Nina events for example."But we're getting these
increasingly warm temperatures - not just for Australia but globally - and
climate change, global warming is clearly continuing.http://www.abc.net.au/news/stories/2010/01/05/2785653.htm
