Tue Jan 5, 2010 9:24am EST SYDNEY (Reuters) – Australia experienced its hottest decade on record from 2000 to 2009 due to global warming, the nation’s bureau of meteorology said on Tuesday, as annual summer bushfires again burn drought lands and destroy homes. The average temperature in Australia over the past 10 years was 0.48 degrees Celsius above the 1961-1990 average, said the Bureau of Meteorology said in its annual climate statement. And 2010 is forecast to be even hotter, with temperatures likely to be between 0.5 and 1 degrees above average. “We’re getting these increasingly warm temperatures, not just for Australia but globally. Climate change, global warming is clearly continuing,” said bureau climatologist David Jones. “We’re in the latter stages of an El Nino event in the Pacific Ocean and what that means for Australian and global temperatures is that 2010 is likely to be another very warm year — perhaps even the warmest on record.” … The year 2009 will be remembered for “extreme bushfires, dust-storms, lingering rainfall deficiencies, areas of flooding and record-breaking heatwaves,” said the bureau. In fact, 2009 was Australia’s second warmest year on record, with the annual mean temperature 0.90 degrees Celsius above the 1961-1990 average, driven by three record-breaking heatwaves that caused Australia’s most deadly bushfires, killing 173 people. “To get one of them in a year would have been unusual. To get three is just really quite remarkable,” said Jones. Outback Australia was warming more quickly than other parts of the country, with some inland areas warming at twice the rate of coastal regions, said the bureau. But as Australia warmed, with large tracts of the country battling a decade-long drought, the northern part of the country was becoming wetter, said the bureau. Floods now cover large parts of northern New South Wales state and the tropical state of Queensland. …
