The now-sacked Climate Commissioner Tim Flannery and other warmists once claimed that global warming had caused droughts in the east and south of Australia. Flannery: Over the past 50 years southern Australia has lost about 20 per cent of its rainfall, and one cause is almost certainly global warming. 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. 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. But then the rains returned and washed out this alarmism: The Climate Commission admitted it could not say those now-gone droughts had been caused by global warming or that we would get less rain - expect for one part of Australia that remained stubbornly dry: It is difficult from observations alone to unequivocally identify anything that is distinctly unusual about the post-1950 pattern [of rainfall]… Our capability to project future changes to rainfall patterns, apart from the drying trend in southwest Western Australia, remains uncertain. The IPCC hangs on to drought in Western Australia as the canary in the global warming coal mine: According to regional findings by the IPCC, temperatures have increased between 0.4 degrees and 1.25 degrees in Australia… Longer dry periods are projected in south-west Western Australia and an increase of floods and droughts is very likely in Australia’s agricultural production areas. And there is no doubt there has been a shift in the WA climate that has brought less rain for some time: But could that shift now reverse, with good rains returning this year to Western Australia? The rain in Western Australia has been relentless due to a series of cold fronts which have swept across the region. In Perth, only ten days of the month were dry. 144.2mm of rain was reported in the city and the airport received a little more, 169.6mm. This is ... the highest rainfall total since 1944. Elsewhere the rainfall was even more out of the ordinary. 130km to the southeast of Perth, the town of Pingelly was drenched by more than 104mm, making it the wettest September in 108 years. Pingelly is situated in what’s known as the Wheatbelt, a region of Western Australia which is famed for its agriculture. If the rainfall of the past does return to WA, what will the warmists say next?
