NASA's Goddard Institute for Space Studies (GISS) has placed 2009 as the warmest year in the Southern Hemisphere since records began 130 years ago, and the past decade as the warmest globally.
Globally, 2009 tied with 1998, 2002, 2003, 2006 and 2007 as the second warmest year on record after 2005, according to the GISS analysis of planetary temperatures.
The decade from January 2000 to December 2009 was clearly the warmest since modern instrumentation was introduced in 1880.
"There's substantial year-to-year variability of global temperature caused by the tropical El Nino-La Nina cycle", said GISS director James Hansen.
"But when we average temperature over five or ten years to minimize that variability, we find that global warming is continuing unabated."
Over the past three decades, according to the GISS analysis, the global average temperature has increased 0.2 degrees Celsius a decade.
