CSIRO: Queensland’s Drought Wasn’t “Global Warming”, Nor These Floods, Either

The CSIRO mentioned in the title is the Peak Government body for scientific research, the Commonwealth Scientific and Industrial Research Organisation, founded in 1926…..TonyfromOz.

Remember all the warmists who once claimed that global warming caused the Queensland drought, which would go on and on?

Here’s a few of them…

Queensland Premier Peter Beattie, 2007:

Given the current uncertainty about the likely impact of climate change on rainfall patterns in (South Eastern Queensland) over coming years, it is only prudent to assume at this stage that lower than usual rainfalls could eventuate.

Global warming activist Tim Flannery, 2007:

We’re already seeing the initial impacts and they include a decline in the winter rainfall zone across southern Australia, which is clearly an impact of climate change, but also a decrease in run-off. Although we’re getting say a 20 per cent decrease in rainfall in some areas of Australia, that’s translating to a 60 per cent decrease in the run-off into the dams and rivers. That’s because the soil is warmer because of global warming and the plants are under more stress and therefore using more moisture. So even the rain that falls isn’t actually going to fill our dams and our river systems, and that’s a real worry for the people in the bush.

Flannery again:

Over the past 50 years southern Australia has lost about 20 per cent of its rainfall, and one cause is almost certainly global warming….Desalination plants can provide insurance against drought. In Adelaide, Sydney and Brisbane, water supplies are so low they need desalinated water urgently, possibly in as little as 18 months.

Warmist scientist David Karoly, 2003:

The Murray-Darling Basin… covers towns north to Toowoomba, west to Broken Hill and south to Victoria and South Australia… Drought severity in the Murray Darling is increasing with global warming… This is the first drought in Australia where the impact of human-induced global warming can be clearly observed.

Queensland Conservation Council:

Reduced rainfall due to Global warming will lead to decreased overall water availability… In part, the SEQ water crisis has been caused by climate change

Climate Change Minister Penny Wong, 2008:

We know the IPCC, the Intergovernmental Panel on Climate Change, said by 2050 that Australia should expect around about a 25 per cent reduction in rainfall in the southern part of the Australia… So there is a very, very sound body of evidence that indicates that climate change is and will have an impact on rainfall in the Murray-Darling Basin and in southern Australia.

Well, a report last year from the warmist CSIRO – yes, the CSIRO – concluded that perhaps global warming wasn’t to blame after all, and the drought would now be followed by years of rain. It was perhaps easier to say that with the drought already broken, but let’s be grateful that the global warming hype is crumbling after so many years of irrationality and opportunism, not to mention government waste:

The recent South-East Queensland (SEQ) drought was likely caused by shifts associated with climate variability over decades rather than climate change, according to the findings of a team of CSIRO researchers led by Dr Wenju Cai.

“We found that, unlike in South-West Western Australia, climate change plays little part in the SEQ rainfall reduction, but cannot be ruled out,” Dr Cai said.

The research team aimed to determine whether the SEQ’s recent rainfall reductions were partly due to climate change and, if so, whether dry conditions will occur there more often in the future.

“At this stage, renewal of a rain-generating process with La Niña bringing higher rainfall to SEQ might be expected to last for 10 to 20 years,” Dr Cai said.

By then, of course, the expensive desalination plant build for Brisbane in expectation of the permanent drought warmists predicted was about to be mothballed, thanks to the rain alarmists like Flannery swore would dry up.

But note now how the warmists turn on a dime, attributing the heavy rain the CSIRO said would be brought by a La Nina to man-made warming instead. Again, some examples…

Ian Lowe, head of the Australian Conservation Foundation:

The Queensland floods are another reminder of what climate science has been telling us for 25 years, like the recent long-running drought, the 2009 heatwaves and the dreadful Victorian bushfires. As well as a general warming, increasing sea levels and altered rainfall patterns, climate modellers confidently predicted more frequent extreme events: floods, droughts, heatwaves and severe bushfires.

Ellen Sandell, head of the Australian Youth Climate Coalition:

Scientists such as Professor Vicky Pope, head of climate change advice at Britain’s Met Office, and Dr Kevin Trenberth from the US National Centre for Atmospheric Research have pointed to the evidence showing a warmer world is a wetter world, due to increased water vapour and energy in the atmosphere leading to more frequent and intense storms.

In The Age this week, Professor David Karoly from Melbourne University’s school of earth sciences was quoted as saying that the wild weather extremes were in keeping with scientists’ forecasts of more flooding and more droughts as a result of high temperatures and more evaporation.

What was that about needing to “listen to the scientists”?

I guess that when it comes to listening to a Karoly, it depends on whether you listen to him back when he was predicting droughts, or now when he says he predicted these floods:

Professor Karoly stressed individual events could not be attributed to climate change. However, he said the wild extremes being experienced on the continent were in keeping with scientists’ forecasts of more flooding associated with increased heavy rain events and more droughts as a result of high temperatures and more evaporation.

But let’s repeat what the CSIRO announced a couple of months ago to little publicity: the drought wasn’t global warming, and these heavy rains aren’t either.
