This forum is about wrong numbers in science, politics and the media. It respects good science and good English.
I am having a bit of trouble.
It was all very well when we lived in the era of Global Warming because then we had a situation where nasty old man was causing terrible damage and it would cost a fortune to put right.
But now we have moved on to Climate Change, Abrupt Climate Change and whatever Holdren now calls it.
I notice no one actually refers to man's causing it except when they talk about warming.
So, the concept of climate change was that temperatures can go down as well as up, sideways and presumably upside down. But it is difficult to see how man can be responsible for all, some or any of it when it is so unpredictable or changeable.... but of course, the link was made when we spoke of warming and now the subconcious link remains whatever happens.... its wonderful how propaganda works isn't it?
"Willy E,---AGWers---refer to him as an amateur.---There was a time when that meant a great deal in the realms of natural philosophy".
It still does J. Consider the dictionary definition of the words Natural and Philosophy:-
Natural ( of, existing in, or produced by nature: 'natural science'; ---).
Philosophy ( the academic discipline concerned with making explicit the nature and significance of ordinary and scientific beliefs and investigating the intelligibility of concepts by means of rational argument concerning their presuppositions, implications, and interrelationships.)
So, 'Willy E', a self confessed amateur scientist, now gives us a definitive explanation of how the 'Weather Machine' maintains the equilibrium of our Climate. He does so, solely using the Laws of Thermodynamics and empirical observations; consequently, every step of his workings and proofs are Immediately Verifiable by standard scientific procedures.(In my opinion, this one piece of work by Willis Eschenbach heralds the extinction of the AGW movement! From now on, we can only witness their death throes, and they will take everyone who adheres to their dogma down with them, from Presidents to Peasants). --- Yes, I think that 'Willy E' is simply, now, the most important man in the Western World.
The Victorians, I believe, were the first to equate scientific endeavour with the amateur; probably because they realised that once a scientist accepts a paymaster, (rather than a sponsor), his essential innocence is lost, he can no longer properly serve the interests of humanity in the understanding of our universe. --- For me, the greatest accolade the World can bestow on a scientist, is to say that this man, or woman, is a Natural Philosopher.
If memory serves me correctly this explanation, or something very similar, was presented in one of the textbooks we had when I was at grammar school in the late 1960s.
The mechanism makes complete sense from a feed back point of view, the standard AGW models are frankly impossible being tuned to a very narrow stability range with a vastly inadequate gain loop. Interestingly the mechanism is essentially that by which a Stirling engine operates.
Having at one time been, allegedly, expert in thermal imaging I find the continual harping on about CO2 absorption driving AGW more than a little annoying. Within the thermal imaging community it has always been axiomatic that CO2 band transmission falls to essentially zero over path lengths between 1 1/2 and 2 1/2 miles depending on altitude, weather conditions and who's measurements you choose to use. Hence all CO2 band radiation is already absorbed within the troposphere so further additions have no effect. If there had been any useful transmission in the CO2 bands the thermal imaging community would be exploiting it. A couple of decades ago I was able to demonstrate, as part of an investigation into inexpensive short range IR systems, that exploiting this part of the spectrum gave sufficient performance gains to allow un-cooled detectors to be used but the effective range proved, in practice, to be marginal for the application.
Thanks for that, Clive.
If I wasn't convinced before that the CO2/GW argument is nonsensical, I certainly am now.
Do you perhaps have any references for the path length of CO2 absorption?
I know that, sooner or later, it's going to crop up in discussion, so it would be nice to have something solid to point to.
I have a note that the 1 1/2 mile figure can be found in Infra Red Systems Engineering by Hudson but a quick skim though my copy hasn't located it. I shall have to find time to sit down and read it properly again. The longer estimate would have been derived from data in either or both the Handbook of Military Infra Red Technology or its multi volume successor The Infra Red Handbook (title?). Most likely the latter given the period when I did the work. Unfortunately I don't have a copy of The Infra Red Handbook so I can't check (worst £50 I ever saved was turning down an offer of the last stand copy about 5 minutes before an exhibition ended!) and the data in my copy of the Handbook of Military Infra Red Technology doesn't look sufficiently familiar. although there is at least one suitable graph from which the extinction co-efficient can be derived and hence absorption path length estimated.
I managed to get a sight of the current Infra Red & EO Handbook but couldn't see any simple statements there. Sorry.
I'll try to source one of those publications - or get a friend to do it for me ;-)
