So yes, there has been a moderate degree of warming over the last century, but we are a long way from understanding the climate system in sufficient detail to be ascribing individual weather events to the effects of climate change, despite the efforts of political shysters like the minister for climate change, Greg Combet, and Greens senator Christine Milne to do so.
Combet just yesterday: "Clearly, one of the most worrying aspects of climate change is what this could mean for the frequency and intensity of extreme weather events such as droughts, heatwaves, cyclones and floods."
Milne trying to milk the cyclone Yasi tragedy for political gain: "This is a tragedy, but it is a tragedy of climate change. The scientists have been saying we are going to experience more extreme weather events, that their intensity is going to increase, (and) their frequency."
Well, maybe, but then again, maybe not.
The Australian has forced the CSIRO to release a number of papers by way of a freedom of information request. One of those is a paper by researcher Debbie Abbs that points to a somewhat different possible future.
Her paper predicts that rising temperatures may result in a fall in the number of tropical cyclones. Despite what the newspaper's headline might suggest, the paper itself did not deal with the possible future intensity of cyclones, though Dr Abbs says that it is "expected" that the intensity of some storms will increase.
The paper does highlight though something that we sceptics have been trying to get noticed for many years now, and that is the degree of uncertainty that exists in climate science. The science is by no means settled.
So another researcher, meteorologist Kevin Walsh, an associate professor at the University of Melbourne, said he was "preparing to publish research with similar but less extreme findings than those of Dr Abbs."
His yet to be published paper predicts that tropical cyclone activity in Australia's north will decline by 20% by 2100, and that the most intense ones will be only slightly more intense.
So we can see what a scientifically illiterate 'carrion crow' Christine Milne was being when trying to take advantage of the recent destruction in Queensland, whereas Combet (rumoured to be something of a climate change sceptic himself) talks rubbish he probably at best only half believes.
