A positive response to climate change : Comments

By Bernie Masters, published 10/10/2008

How should Australia respond to the threat of climate change and global warming? Well not by sitting on our hands ...

To answer your questions ... yes, and I do. I also think you misunderstand where I’m coming from.

However, your post to Taswegian was/is premised on a fallacious argument. If we follow it to its conclusion, even wind power and coal have radiation residue issues, as does the Sun itself.

I agree, many people have ‘hang-ups’ about nuclear power, sometimes justified. Nevertheless, this form of energy must be an option to supply base-load energy (I’m particularly hopeful for 4th generation breeder reactors) and in many countries it is.

Having said that, I don’t think Australia needs them ... yet.

Closed loop HFR technology in Oz is different to geothermal energy sources in some overseas countries, and it was/is disingenuous to associate geothermal with “significant radiation issues” and the Hunters Hill watch factory.

Q&A,

Re AGW FWIW AFAIK IMHO IDKWTFYATA.

I suppose I could waste a large portion of my time trying to make sense of your nonsensical post, but I won't. But I am interested - should those with an alternate (sic) view publish in your proscribed media before or after they are tortured?

Q&A,
you state that-
'Time-series analysis of temperature anomalies show that the Earth’s climate has been warming since about 1850 – ergo, since the dramatic increase in fossil fuel burning and expansive increase in agricultural activity.'

Of course the climate has been warming,the earth has been warming since the end of the little ice age. The main fault with most of the analysis presented as 'proof' of AGW is that they won't go back that far or try to eliminate it altogether. This hockey stick trend that alarmists are so fond of is replicated several times in reconstructions that go back several thousand years, unless of course you cherry pick data as Mann et al did. Almost all 'proofs' of AGW try to leave out or minimise the little ice age and the medieval warm period.
As for the paper you cite (Geophys. Res. Lett. 35, L18701, 2008), The abstract reads-

"To distinguish between simultaneous natural and anthropogenic impacts on surface temperature, regionally as well as globally, we perform a robust multivariate analysis using the best available estimates of each together with the observed surface temperature record from 1889 to 2006."
They are making the same mistake. It's a fairly recent paper and it remains to be seen if it holds up. My bet is it won't.

The world population keeps growing at 80 million a year and nobody
says boo. Its just a given. So the whole Australian population
could be replaced in 90 days of human breeding.

I went on about this stuff 30 years ago, as a student in Paris.
Nobody cared then and they don't care now, or very few anyhow.

So I've kind of given up on humanity, clearly nature will have to
sort it out, as Darwin predicts in his Origin of Species.

Feelgood solutions to make us all feel better are clearly that.

Best just to enjoy the remaining years, let the crunch happen
when it does and people will learn the hard way, as they always
do.

Some things we cannot change and if we cannot, its pointless
getting stressed about them

Solar power has other options beyond photovoltaic cells. Heating sodium and using the heat to convert water to steam to turn generators is an option.
Storing heat to provide power without the sun is in desperate need of more R&D.
Meltdown isn't the biggest concern of nuclear power for me, it's what do we do with the waste, and the many thousands of years of dangerous radiation that emanates. Chemical waste is bad enough but radioactive waste, where to put it, and storing it safely... we are barely capable of it. Our civilisation has only 7000 years of records (no offense indigenous aussies, who had it right in the first place).
Geothermal needs more R&D too. It's not a reality for us yet.
Tidal power?
A world electricity grid that takes adavantage of the sun always shining somewhere.
Geosequestration scares me, and the posibility of there not being enough space for our CO2 down there.
C02 capture? More R&D please. I'm wary of Clean Coal as are most of us.
Humans went to the moon... we can do anything we want, if we put our heads and hearts together.

Yabby you've said it. Let it happen in its own time - this decade of anti-rationalism has laid the groundwork for a tough future. Sufficient will to postpone, avert or mitigate AGW simply doesn't exist.
