“the logarithmic relationship is purely a convenient fit of data to a curve. It is only relevant to the range of data fitted. In other words, It’s empirical, not based on any underlying truth.
I can’t find any obvious reference, so Angech will have to trust me. (!)”‘
Data fitting to a curve? We do see a lot of it. Nothing wrong on it’s own.
The concept of doubling taken to extremes proves the point that the concept of the doubling is purely curve fitting and not based on the actual underlying physics. It becomes physically implausible at the lower levels, hence it can only be an observationally based observation.
Which is all I was saying.
The concept that there is a physical basis purely on the concentration is wrong at other parts of the curve.
I did put a quote up from Arrhenius on doubling, quadrupling, halving and quartering. I hope that bit can be repeated and seen since there were two replies to it.
Basically he said that a halving would drop it by 4C and a quartering by 8C, so it seems logical that he implied this was an ongoing feature of his claim.
Interesting aside was the fact that the CO2 effect is primarily at higher levels where the H20 does not reach, basically a blanket outside the blanket H2O doing all the heavy lifting.
Everyone happy with that concept?

“What do you gain from such comments that so lack specificity that they are completely worthless (with respect to a reasoned discussion – they may have value in winding people up, I suppose)?”
Joshua, general comments are not always worthless.
A reasoned discussion must allow both sides of an argument, or is there only one side allowed to yours?
If that is the way, then there is no discussion and any mention of points to the contrary will be deemed as vexatious and winding up people.
I find, and again correct me if I am wrong, that this view of discussions often applies to both sides of the argument at different sites. Again, personally, I appreciate your views but find an amaurosis in your comments addressed mainly to one side. This is despite the fact that you have shown at times a genuine balance on the arguments.
I could sit down, take the views of people here, put a skeptic name to the argument and find it would be shouted down. I could take a skeptic argument, put a name from here down and it would not raise a murmur.
I do not have to do anything to wind people up, they are, like me, already wound up and just need a trigger like a hint of an opposing view.
In real life I am sometimes socially awkward and this winds some people up unintentionally. I like making jokes but do take offence too easily when the joke is at my expense. My problem, I live with it.
In regard to the issues ATTP raises I was pointing out, as usual, that there are benefits to global warming as well as detriments. I do not think the earth is one uniform set in concrete perfect place that cannot or should not be changed so that every little shy coral can live its undisturbed paradise. The world is also wrongly painted as only savage tooth and claw survival. Somewhere between there is a large balance range. We can move ourselves in and out of it and have nature do it to us whether we want it to or not.
Nothing to date shows that a warmer world will be that that much badder for us. Extreme events will always occur at rare intervals for each type of rare event but extremely frequently if one multiplies the number of different rare events by the number of different localities and times they can occur in.
Hence the relative unimportance of the big events and the recourse to a multitude of stories about the hottest/coldest/driest/wettest peatbog/methane/vortex/elNino/tree loss/deforestation flood/x1,000,000 events of climate change that might, or might not be influenced by human activity.
Do you really want to face this can of worms honestly?
And yes, AGW or even CAGW are some of the real possibilities that may exist, or not.
Even in the face of my comment.
