Salby is an idiot. This is how important anthro CO2 is...
Not me being right, just making you wrong that time, as usual.Thereby admitting you're one of those haughty closed minded holier than thou know it all types who think they're always right about everything all the time.
Making me right, this time.
No, thank you Piezo, but may I ask , what are you doing? Are you going to be scientific about this or just want to run that confirmatory bias you said you have?Stu, thanks for discussing the science rather than personalities. I don't know who Monckton is but he admits he is not much of a scientist. I guess he is a global warming "hobbyist" as some of us here are. But I did think that much of his critique of Pettersson and Born was scientifically sound. I noticed a number of obvious errors but I didn't think they were substantive. Pettersson on the other hand is a well trained scientist and his training makes him especially qualified with regard to using radioisotopes as a label.
I want to look at Petterssons work more carefully, because I am still unclear on how he was able to distinguish disappearance of Bomb C-14 due to more rapid turnover, from disappearance due to dilution from anthro-CO2 with slower turnover. The argument is there I'm sure, I just have to dig for it.
Salby's work seems to me almost genius in its consistency and its meticulous consideration of phase shifts. His finding that CO2 mirrors very closely the integrated Temperature with the temperature leading and CO2 lagging is a beautiful price of work as far as i'm concerned.. Going forward, I think any models that are inconsistent with Salbys work will have to be seriously questioned. Salby has never intimated that that's all there is too it, or that Anthro CO2 plays no role at all, but it is apparently less important than previously supposed.
No, thank you Piezo, but may I ask , what are you doing? Are you going to be scientific about this or just want to run that confirmatory bias you said you have?
You stated in words to the effect that C14 cannot be used to determine anthropic CO2 in the atmosphere. Then you are bowled over by those like Mockton et al who use a measurement of anthropic CO2's C14 diminishing in the atmosphere. You can't have it both ways.
On the separate issue of your effusive willingness to run toward Mockten and Salby, that seems to suggest you tend toward AGW denial rather than constructive skepticism. They raise queries (some of them very unsound if not downright ridiculous) which then immediately begs more questions. For instance, the Bern Model brought up (not by you) as a red herring against the main issue of using C14 in the first place, establishes itself as being designed to cover the redistribution of carbon in time scales of decades, through to centuries for the full carbon cycle. Not just for short term periods of decay.
I dare say there are adjustments and rethinks on many aspects to do with this so that more knowledge can be brought to it. Doubting the doubters gets to the science also, rather than curve fitting denial into things and trying to overturn the laws of physics that allow for the anthropic measurement of CO2, and facts like AGW.
You have a good point. I overstated if I said or implied that C-14 could not be used to follow anthro C contribution to the atmosphere. If I did that, I was wrong, and I should have said instead that I have serious questions about the validity of that method. And that was before I read Pettersson. I was basing my opinion at that point on a scientifically informed guess on my part. Then when I read Pettersson (Mockton doesn't enter in here) I found his arguments pretty compelling. Here is the thing, Pettersson has said that the spike in C-14 from the bomb testing furnished the perfect opporunity to determine the turn-over rate of CO2 by following the disappearance of C-14 in the atmosphere. The Bomb testing just about doubled the C-14 content. One knows the radio decay rate and also the rate of disappearance of C14 from the atmosphere. The latter is much in excess of the decay, which is very small over fifty years since the half life is 5700 yrs. But I want to figure out how Pettersson determined that the disappearance is due to CO2 turn-over rather than dilution by anthro-CO2. It seems that the IPCC is assumming a long turnover time. Is that correct however? There must be another observation or assumption to be able to distinguish between dilution and rapid turnover. Maybe it's obvious to you, but it is not to me. I'm looking for that additional assumption or bit of information. I'll let you know if I find it. I'll admit to bias here, as a much shorter turn over than the IPCC has assumed seems intuitively correct to me, considering the uptake by plants and the rough estimates of the natural sinking and sourcing from, I think, mostly satellite data. The rates of natural sinking and sourcing, according to Salby, are close to two orders greater than the anthro-C contribution rate. And Salby is a first-rate atmosphere physicist. Anyone can make a mistake, but there is no question about his training and experience. It seems his personality has created difficulties for him, but he is definitely no armchair scientist.No, thank you Piezo, but may I ask , what are you doing?

According to who?Pettersson anb Salby are both error prone and two of the least repected climate scientists in the world....
That comes as no surprise.
With respect piezo I think you are looking for an incorrect thing. I mentioned all this above, but just to recap.It seems that the IPCC is assuming a long turnover time. Is that correct however? There must be another observation or assumption to be able to distinguish between dilution and rapid turnover. Maybe it's obvious to you, but it is not to me.
