Attempts to control atmospheric CO2 are futile

From Jo Nova

Futile for so many reasons, practical and political. Grinding developed economies to a halt is an entirely unrealistic aim. China and India will press on with industrialisation in order to raise their populations out of a miserable life of poverty. Much of the developed world has its eyes firmly fixed on the forthcoming GFC Mark II, and when the going gets tough, touchy-feely environmentalism gives way to hard-nosed reality. Without anything else, this simple list demonstrates why adaptation is infinitely preferable to attempts at mitigation.

And now another nail in the coffin, as respected climatologist Murry Salby claims that natural drivers have a far greater effect on CO2 levels than anthropogenic sources, and if anthropogenic source have little effect, then reducing them by means of carbon taxes will in all probability achieve nothing for CO2 concentration, much less the climate:

Carbon dioxide is emitted by human activities as well as a host of natural processes. The satellite record, in concert with instrumental observations, is now long enough to have collected a population of climate perturbations, wherein the Earth-atmosphere system was disturbed from equilibrium. Introduced naturally, those perturbations reveal that net global emission of CO2 (combined from all sources, human and natural) is controlled by properties of the general circulation – properties internal to the climate system that regulate emission from natural sources. The strong dependence on internal properties indicates that emission of CO2 from natural sources, which accounts for 96 per cent of its overall emission, plays a major role in observed changes of CO2Independent of human emission, this contribution to atmospheric carbon dioxide is only marginally predictable and not controllable.

The podcast of Prof Salby’s talk is here. A paper on this topic is apparently being prepared for publication.

    Gillard has been handed a life-line with the prospect of GFC-II. This is the Labor Party’s only hope of saving face by dropping this futile yet economy destroying tax.

    They could argue that the economic conditions are to unstable at the moment to introduce this tax and they might just come out of it with enough credibility to survive the next election.

    Sure, the Greens will run around wringing their hands but if she doesn’t grasp this life-line, it’s all going to end in tears!

    • Good point Baldrick

        It would be great if Juliar grabbed this lifeline but I think that this lot have been spruking the warmist alarmist line so hard for so long that they actually have come to believe their own propergander.They live in a parallell universe where somehow Sydney will sink under the sea and it migtht never rain again(other then the odd Category 5 cyclone) if the carbon tax is not introduced forthwith.Juliar is ready to fall on her sword and expects her whole sorry bunch of comrades to do the same. It would need an outside force (caucus powerbrokers) to steer this ship away from the rocks and certain destruction,

    Baldrick,

    Remember that Krudd backflipped on the ETS and it cost him his job.

    I think Comrade Gillard’s goose is well and truly cooked whatever she does, if the Coalition can avoid doing anything truly idiotic.

  4. I watched this presentation on APAC on Foxtel. I must admit a broad smile came across my face when Prof Salby said that anyone thinks that the science is settled on this issue is in “fantasia”.
    Thats about as political as he went. When some members of the audience were asking questions that were trying to lead him to make a policitical statement, he avoided this by saying that he has collected the data and you can draw your own conclusions.
    Im pretty sure I know what side of the fence he sits on, but at least he is keeping the politics at arms length which means it is more difficult for him to be labelled or howled down by the warmists.

  5. Just listened to this & its like someone opened a door & let in the fresh air. I sent this to my Pro Climate Change friend & he has been floored. This needs to have a much wider circulation.
