Perhaps Peter hasn't noticed, or has consciously kept his mind averted from, the very cool, wet, but virtually storm free spring the east has experienced.

Hell, there's even water running down the Darling, reaching the south coast.

No of course he wouldn't want to notice that, all that water is not bad news.

Anti-green, you acknowledge that: << humans do modify climate to a certain extent, for instance the heat islands effect. In theory a yellow corn field should absorb less heat then a dark green bush leading to local cooling. >>

So, if you can see that significant anthropogenic changes do occur, even on a very small ‘corn field’ scale, then why are you so adamant that AGW doesn’t exist on the massive scale of vastly cleared landscapes and released fossil carbon?

It doesn’t add up.

<< All this is a long way from proving that the industrial emission of carbon dioxide is the principal driver of the global climate. >>

It isn’t really, you know. But who has to prove anything? The evidence is there that AGW is probably real and very significant. That should be good enough for us to implement policies worldwide in the interests of erring on the side of caution. We don’t have to and most definitely shouldn’t wait for irrefutable proof.

However, this is really as aside to the WA water crisis. I think that climate change is the wrong thing to concentrate on here. Continuous rapid population growth is the primary concern.

WA, or southwest WA at least, should become a stable-population steady-state region. The current water situation, and just plain commonsense, tells us that this should happen… with urgency!

Got to say, Ludwig, that here in south-west WA it was the strangest winter I've ever experienced. Day upon day of cold sunny days with clear blue skies...it really was very unusual.

Another in McMahon's long list of second-rate propaganda articles. He's been out of his depth since he stopped driving tractors.

Perth has hot weather and that's proof of globacl warming,he says. Pathetic.

In response to your post:
1. Assigning causation is a major problem in science. It has been so at least from the time of David Hume. The late Sir Austin Bradford Hill laid down some criteria in the year 1965 to the Royal Society of Medicine. A detailed summary can be obtained at the following site- this is not a copy of the original paper.

www.drabruzzi.com/hills_criteria_of_causation.htm

In the final analysis assignment of causation depends on “scientific judgment.”

2. The destructive energy released in certain weather events is orders of magnitude greater than any human activity. I understand for instance that the energy dissipated in a grade 5 cyclone is orders of magnitude greater than that released say in an atomic bomb.

Hold press - localised regional weather event proves climate doomists right!

Yes, thats right - a cold, wet winter and spring in Victoria, Australia has finally given advocates of Global Cooling (~1975) cause to claim victory over the dirty, scum sucking sceptical pollution-funded lobby. Spokesman Meter McPhahon was seen to be dancing in the streets, singing "We were right! We were right!", at least until he had to stop to find his slippers and put his tracksuit pants back on.
