Shock: Murray-Darling warming 'not due to CO2'

"It's the Murray, darling."

"It's the Murray, darling."

Another Science is Settled Alert, as researchers at Newcastle University conclude that elevated temperatures in the Murray-Darling basin were a combination of natural factors:

Lead researcher Associate Professor Stewart Franks, from the University’s Faculty of Engineering and Built Environment, said the findings were based on known principles of physics.

“Senior climate change researchers have claimed that higher temperatures lead to higher moisture evaporation and that this is why the Murray Darling Basin has experienced such a harsh drought,” Associate Professor Franks said.

“This is incorrect and ignores the known physics of evaporation.

“During drought, when soil moisture is low, less of the sun’s radiant energy goes into evaporation and more goes into the heating of the atmosphere which causes higher temperatures.

“Most importantly, the elevated air temperatures do not increase evaporation but are actually due to the lack of evaporation and this is a natural consequence of drought.

“Therefore any statement that the drought experienced in the Murray Darling Basin is a direct result of CO2 emissions is fundamentally flawed.”

Associate Professor Franks said the findings of the study highlighted the importance of getting the science right.

“A key concern is that the Intergovernmental Panel on Climate Change – which advises governments around the world – has used the Murray Darling Basin and incorrect science as an example of CO2 induced climate change.

  1. I think you are making the mistake of confuisng real science with “Penny Wong Science”.

    With apologies to Lewis Carroll’s ‘Through the Looking Glass’:

    ‘When I use a word,’ Penny Wong said, in a rather scornful tone,’ it means just what I choose it to mean, neither more nor less.’

    ‘The question is,’ said Alice, ‘whether you can make words mean so many different things.’

    ‘The question is,’ said Penny Wong, ‘which is to be master – that’s all.’
