Ozandy, thank you. You provide a wonderful example of exactly what I am talking about. You can rattle off all the evidence that has been put forward to support AGW, but nowhere in your post is there the slightest indication that you have ever read anything from a single opposing viewpoint. What is your take on the Urban Heat Island effect, for instance? How do you explain the absence of stratospheric warming? Why did the removal of 80% of weather stations from the statistics after 1970 not affect the reliability of the measurements that they were supposed to be providing? Can you name which oceanic regions have actually been tested for increasing acidity? Do you know the normal range of pH measurements in aquatic environments? Your pro-AGW blogs are unlikely to tell you much about these uncomfortable issues; which is why you need to broaden your reading.

Here we go again !

YOU ARE ALL WORRYING ABOUT THE WRONG PROBLEM !

Sorry for shouting, but I need to attract your attention.
Long before the higher suburbs of Sydney become water front properties
we are up against an energy drought.

The amount of oil is depleting and the effects on industry, food, and
employment will be really something to worry about.
Forget all this nonsense about resource industries plotting to undermine
the AGW campaigns, they are too worried about how they are going to cope
in an era of energy depletion.

By the time our industries start slowing down the amount of coal and
oil being consumed will decrease faster than any CO2 program could
achieve anyway. There is nothing that Australia could do to affect
the CO2 levels in world atmosphere.
The ETS schemes are finished as the European ETS scheme has collapsed
from E12 to E1 due the rorts in the system. The same would happen here.
The numbers you need to worry about are when the cost of oil to the
United States exceeds 4% of their GDP.
It is around US$90 to US$100 a barrel.
From now on we are all in the same boat and it is now time to start
the biggest changes any of us have ever seen.

Good on you Bazz, but this article is not about that, so your concern is off topic.

it's a good topic, though - why not write a paper and send it to OLO for publication and we'll all consider it.

please do write such an article

Well Amicus, I know what you mean but it is not quite off topic as
I was saying that the subject is invalid.

I will have a think about it and try to gather better information.
