2009 Australia's second hottest year on record -- according to the BOM

But now we know how Australian temperature records are compiled, you would be gullible to believe them

THE past calendar year - 2009 - was the second warmest on record in Australia since 1910, the Australian government's Bureau of Meteorology reported today. The bureau said the high temperatures were driven by unusual or extreme heatwaves, with a temperature trend consistent with global warming, Dow Jones Newswires reported.

Australia's annual mean temperature for 2009 was 0.90 degrees Celsius above a 1961-90 average, making it the nation's second-warmest year since high-quality records began in 1910, the bureau reported in an annual climate statement. The warmest was 2005.

High temperatures were especially notable in the south-east during the second half of 2009, with Australia nationally and the states Victoria, South Australia and New South Wales independently all recording their warmest July-December periods on record.

Extreme heatwaves occurred across much of southern Australia during late January/early February, resulting in a new maximum temperature record in the Victorian capital Melbourne of 46.4 degrees and a new Victoria state maximum temperature record of 48.8 degrees.

An unusual winter-time heatwave occurred in August over large parts of the inland and resulted in Australia's warmest August on record, while a prolonged heatwave occurred during November across central and south-east Australia. "Based on the analysis of daily maximum and minimum temperature data...there are clear upward trends in the number of hot events and downward trends in the number of cold events over the period 1960 to date, consistent with global warming," the bureau reported, without citing a cause for global warming.

The end of 2009 also saw the end of Australia's warmest decade on record, with a decadal mean temperature anomaly of 0.48 degree above a 1961-90 average [Picking an arbitrary base-year for your averages is fun]. This meant that in Australia, each decade since the 1940s has been warmer than the preceding decade, it reported.

As for rainfall, the overall Australian mean rainfall total for 2009 was 453 millimeters, down a little from a long-term average (1961-90) of 464 mms, it reported. During July to October 2009, serious rainfall deficiencies were experienced over large areas of Queensland and isolated parts of New South Wales, consistent with the development of an El Nino event during this time.

  2. We are the dryest continent on Earth. That is recorded fact. We are also subject to some very extreme weather events. That too is recorded fact. The warmest year since 1910? That means there were warmer years prior to that year when CO2 was not considered to be a greenhouse gas and a potentially harmful enviromental disaster causing substance. Hmmmmmmm.

  3. Much of the country has/is been in drought. Stands to reason that it would be hotter. Cloud cover and soil moisture tend to keep temps down. But hey, don't let that keep you from implementing economically destructive policies to "save the planet," Leftists.

  4. The late, great John Daley started investigating the actual locations used by the various weather bureaus for measuring temperatures. (Watts Up With That has taken up the task with a vengeance). He found locations being deliberately moved from their original location in order to get record high numbers - for example using natural amphitheatre formations that intensify the heat. Combine that sort of thing with the shonky 'adjustments' shown up in the Climategate scandal - especially of those in and around Darwin - and it's no wonder that record high values are being reported.

    Meanwhile, we have had the coolest summer I can remember in Newcastle.
