From an Indian skeptic and blogger. A rejoinder and a challenge to Mr Garnaut.
a) the current episode of MILD warming is PRIMARILY natural;
b) the impact of manmade CO2 is real but minimal, and unlikely to accelerate with increased CO2;
c) the benefits of increased CO2 appear to be significantly greater than costs;
d) the Earth held far greater levels of CO2 in its atmosphere in the past and did not experience runaway global warming. A large number of natural processes (plants, primarily) exist on Earth that check runaway effects;
e) projections of warming and sea-level rise by climate models have, so far, been grossly exaggerated; and
f) IPCC and many senior scientists from reputed institutions have published numerous false reports and ACTIVELY prevented healthy scientific debate .
Government funded institutions on this subject have lost credibility, particularly given the large number of independent scientific views that contradict government-supported findings. Group think is a common flaw in all governments, given strong incentives to shut out internal debate.
Check out some of his older posts, there is great stuff there, including some “delectable quotes” from a paper by Demsetz which he especially likes.
This article, by Harold Demsetz, published in the February 2011 issue of The Review of Economics and Law, is perhaps one of the most profound articles published since Hayek’s pathbreaking 1945 paper “The Use of Knowledge in Society“. Demseltz’s article can be downloaded free of cost from the link provided above after you provide your your details. It has been an absolute pleasure to read this paper.

“e) projections of warming and sea-level rise by climate models have, so far, been grossly exaggerated”
Looks like some of them have been wrong, but not in the way Sabhlok Sr thinks:

Jarrah, do you have the training, expertise and a record of work in the field that permits you to form an independent opinion about sea-level rises or any other climate-related issue?
I don’t, but I don’t claim any authority beyond common sense and large measure of skepticism about Green fanatics.
In any case, our nuanced commentator is not contesting a degree of warming, he is politely requesting a thorough cost-benefit analysis so we can have an informed public debate before there is massive increase in regulation and disruption of the economy (and our way of life), most likely with no measurable impact on the climate.

You lot spend so much time debunking the standard science of climate change that I assume you are insecure about your position.
I guess with mentors like Rafe, CL, Samuel and Andrew Bolt it is understandable.

We can dump 9bn of fossil fuel subsidies, deregulate nuclear. NO cost to the taxpayer. GDP positive. Far less CO2 pollution and far less radiological pollution from coal. Cheaper energy.
It would be far more effective than any mitigation scheme.
Let’s do it.

12 Mar 11 at 7:08 pm
The debate has been going on for years – have you not noticed? – and there have been innumerable cost benefit analyses – Stern, Garnaut, Nordhaus and all reach the same conclusion even though they have markedly different discount rates and politics.
The cost of not addressing climate change is high and according to Weitman and others potentially catastrophic.
The cost of addressing it is relatively small – not negligible but manageable. The basic reason being that energy costs (direct and indirect) are a small part of the economy.
Asking for another debate and more cost-benefit analyses now shows only that you have not been following things.
Its not sensible to argue for doing nothing or for claiming to be a sceptic if you are approaching the issue from the position of ignorance.
And wait for the first moron to respond that Stern used a low discount rate. I’ll provide an answer in advance – Nordhaus did not.

Note that it doesn’t mean we should load up with a tax if we can mitigate through microeconomic reform. A CBA being passed for mitigation doesn’t necessarily mean that all mitigation schemes pass.

late news 19 coal miners die in China.
The comparative death rates from nuclear power and coal mining represents one of the positives for nuclear.
http://frankwarner.typepad.com/free_frank_warner/2006/01/us_coal_mining_.html
China’s coal-mining death toll over the last several years:
2000: 5,300 deaths.
2001: 5,670 deaths.
2002: 5,791 deaths.
2003: 7,200 deaths.
2004: 6,027 deaths.
2005: 5,986 deaths.
2006: 4,746 deaths.

I’ve said this before, but in 30 years it will either be substantially warmer than today or it won’t.
The conservative movement for whatever reason have decided to nail their colours to the no-AGW mast. (Or in this case, the “nuanced” no-material-AGW mast).
Which means that in 30 years, the conservative movement will either be discredited in the eyes of most and forced into a series of embarrassing backdowns, or they’ll end up looking like heroes.
It’s a very brave, high stakes move to attach a political ideology to a question of empirical reality.

That cuts both ways, PSC.
The left have done exactly the same thing to the other side of the debate. The green movement, in particular, has put all their chips on this bet.
daddy dave
12 Mar 11 at 10:45 pm
Actually I take that back. If global warming turns out to be a load of cobblers, the green movement will just refocus to the next boogeyman:
* GMOs
* peak oil
* “biodiversity”
* the oceans (toxins, lack of fish, and so on)
* overpopulation again
…the list goes on. So, I guess you’re right, PSC. The green movement won’t give a flying fuck if they were wrong about global warming because there are plenty more bullets in their pistol.
daddy dave
12 Mar 11 at 10:49 pm
PSC,
There have been recent statistically valid studies showing that warming is only in part human induced, much less than previously thought, and the outcome will be much less hotter than the original models predicted.
It’s no big deal and we could deal with it by minimal cost, we can effectively mitigate through microeconomic reform.
Some people unfortunately just love the idea of dreaming up new taxes and licensing schemes.

PSC you are neglecting a couple of other issues. Yes it could be warmer in 30 years. Yes it could be due to AGW. But that in itself is still not sufficient to give carte blanche to emissions reduction schemes. Because 1) they probably won’t make any difference, especially if China and India continue to develop (as I hope they do) 2) it will be cheaper to adapt rather than take action which is likely to be ineffective 3) nuclear power is likely to be widespread – Japan shows that even some of its old plants can survive one of the biggest earthquakes in history. Did you know that Japan’s main island moved 2.4 metres and the earth shifted 25 cm because of the force of the quake.

Obvious, sdfc. Adaptive measures can be targeted against identified problems.
The current greentard position is to expend vast (but unknown) volumes of money on unknown problems with no known outcomes.
See the transcript of the Steve Price/Andrew Bolt interview with the EU ETS woman – she’s here spruiking exactly this sort of nonsensical greenie position. She had no idea what the cost was, and no idea of the outcome of the expenditure.
How can that stance possibly be an efficient use of public funds?
