This weekend the nations press and media is full of this BoM/CSIRO story predicting the big “big dry” drought will return despite the useful post Autumn rains.
Now I do not know anybody who does not accept that Australia’s climate history is dominated by a series of droughts – so predicting future droughts is a bit of a non event. However what the BoM/CSIRO are saying I think is that the “worst drought ever” of the last decade will reappear and continue worsening – I think that is the doomster message.
Anyway – because the CSIRO’s Dr David Post is widely quoted this weekend as being connected with the source report for this weekend media blitz – “South Eastern Australian Climate Initiative” which interestingly came out in May 2010 just before record winter and September rains – I thought it worthwhile looking a bit closer at what Dr Post says.
I came across this fascinating article from January this year headed “No Link – Drought and Climate Change – CSIRO” – where he says –
Dr Post said in January there is “no evidence” linking drought to climate change in eastern Australia, including the Murray-Darling Basin.
“At this stage, we’d prefer to say we’re talking about natural variability. The science is not sufficiently advanced to say it’s climate change, one way or the other. The jury is still out on that.”
The Canberra Times carried a similar article.
So in a few short months Dr Post seems to have changed his opinion 180 degrees on the influence of “climate change” on drought.
