R. W. Wood: Note on the Theory of the Greenhouse
XXIV. Note on the Theory of the Greenhouse
By Professor R. W. Wood (Communicated by the Author)
THERE appears to be a widespread belief that the comparatively high temperature produced within a closed space covered with glass, and exposed to solar radiation, results from a transformation of wave-length, that is, that the heat waves from the sun, which are able to penetrate the glass, fall upon the walls of the enclosure and raise its temperature: the heat energy is re-emitted by the walls in the form of much longer waves, which are unable to penetrate the glass, the greenhouse acting as a radiation trap.I have always felt some doubt as to whether this action played any very large part in the elevation of temperature. It appeared much more probable that the part played by the glass was the prevention of the escape of the warm air heated by the ground within the enclosure. If we open the doors of a greenhouse on a cold and windy day, the trapping of radiation appears to lose much of its efficacy. As a matter of fact I am of the opinion that a greenhouse made of a glass transparent to waves of every possible length would show a temperature nearly, if not quite, as high as that observed in a glass house. The transparent screen allows the solar radiation to warm the ground, and the ground in turn warms the air, but only the limited amount within the enclosure. In the "open," the ground is continually brought into contact with cold air by convection currents.To test the matter I constructed two enclosures of dead black cardboard, one covered with a glass plate, the other with a plate of rock-salt of equal thickness. The bulb of a themometer was inserted in each enclosure and the whole packed in cotton, with the exception of the transparent plates which were exposed. When exposed to sunlight the temperature rose gradually to 65 oC., the enclosure covered with the salt plate keeping a little ahead of the other, owing to the fact that it transmitted the longer waves from the sun, which were stopped by the glass. In order to eliminate this action the sunlight was first passed through a glass plate.There was now scarcely a difference of one degree between the temperatures of the two enclosures. The maximum temperature reached was about 55 oC. From what we know about the distribution of energy in the spectrum of the radiation emitted by a body at 55 o, it is clear that the rock-salt plate is capable of transmitting practically all of it, while the glass plate stops it entirely. This shows us that the loss of temperature of the ground by radiation is very small in comparison to the loss by convection, in other words that we gain very little from the circumstance that the radiation is trapped.Is it therefore necessary to pay attention to trapped radiation in deducing the temperature of a planet as affected by its atmosphere? The solar rays penetrate the atmosphere, warm the ground which in turn warms the atmosphere by contact and by convection currents. The heat received is thus stored up in the atmosphere, remaining there on account of the very low radiating power of a gas. It seems to me very doubtful if the atmosphere is warmed to any great extent by absorbing the radiation from the ground, even under the most favourable conditions.I do not pretent to have gone very deeply into the matter, and publish this note merely to draw attention to the fact that trapped radiation appears to play but a very small part in the actual cases with which we are familiar.
Why is his second to last paragraph wrong?
Firstly, note that unlike the experiments described earlier, this paragraph merely expresses his opinion.
Second, although the troposphere is subject to convection, the stratosphere is not.
Third, in contradiction to his assertion about "the very low radiating power of a gas", the troposphere is largely opaque to infra-red radiation, which is why convection is so important in moving heat up from the surface. Only in the higher (colder) atmosphere where there is less water vapour is the atmosphere simultaneously somewhat, but not totally, transparent to infra-red and thus permits radiation to play a part.

The parable of the Antheap and the Anteater

But alas one day a disaster occurred: a rainstorm washed the heap away, destroying all the order. Not a single ant died, but the Heap aka Hillary was no more.
In GEB the analogy is to processes of conciousness. But I think it works as a loose analogy between individual human beings and cultures1. We might save all the individual people from a given culture - for example, by moving them, or allowing them to move, from a war zone to some place of safety; but in the process so dilute them amongst others that their culture is lost. Or we might kill any number of people, whilst preserving the overall culture2. And so attached to their culture - mistakenly, in my opinion - are some people that they might even prefer the latter option. In our liberal-democratic way we'd like to pick both options, and save all the culture and all the people; but we've not very good when both aren't possible. In theory, I think, we would and should prioritise the individuals, preferring to treat people as individuals rather than members of tribes4. But of course, what do I mean "we", White Man?
Notes
1. Spare me the tedious outrage of comparing people to ants. No, I'm not.
2. In fact this option is illusory; culture is not preserved in this circumstance, only tatters of it.
3. Actually, Aunt Hillary. Geddit?
4. Treating people as individuals is classical liberalism. Treating people as members of tribes is kinda lefty-progressive-DEI-ism; this may be relevant.

AMOC tipping points of no return

Briefly, while this is a time-dependent (~300 year) simulation, the time is not intended to represent any real set of calendar years; instead we start from pre-industrial and increment freshwater, until it "tips" at ~0.6 Sv. The main novelty then is the slow-running time; previous goes at this have tended to dump in the freshwater rather more suddenly, which may have its own effects.
But what's not at all clear from The Conversation, and which only appears rather belatedly in the RC piece, is from the discussion in the paper itself: "In the CESM simulation here, AMOC tipping occurs at relatively large values of the freshwater forcing. This is due to biases in precipitation elsewhere in the models and mainly over the Indian Ocean (37). Hence, we needed to integrate the CESM to rather large values of the freshwater forcing [∼0.6 Sv, about a factor 80 times larger than the present-day melt rate of the Greenland Ice Sheet (55)] to find the AMOC tipping event" to which SR is obliged to reply "in this model, like in most models, you need to add an unrealistic amount of freshwater, because they are in the wrong part of the stability diagram compared to what observational data imply". That doesn't fill me with confidence. What, you wanted more analysis?

History is bunk

And so on to Putin, who apparently - I haven't read it - answered "why did you invade Ukraine" with a half hour history essay. The usual silly people have done the usual silly things - fact checking it - which is to miss the point: that simply thinking this way is wrong. It is the sort of thinking that leads to The Troubles; or the wars in the Balkans - take your pick as to exactly which ones - or the Palestinians deciding it would be an excellent idea to kill as many Israelis as they could. This is no great original insight; others have said much the same.

Move to sustainable food systems could bring $10tn benefits a year, study finds?

But how is it possible for the food system to destroy more value than it creates, given that without it we would all literally starve to death? I'm assuming they're using "value" in the human context here. No humans - or only a few residual hunter-gather-peasant-ag folk - means that value has gone to zero.
The report doesn't actually say. Indeed, as far as I can tell it doesn't count the benefits, only the costs, so I can't see they have any basis for their claim. They assert $15T in costs, of which $11T are from health; and they further say that "A large share of this burden is born by people living with obesity" so this is all bollocks1, because they've failed to event attempt to back up their claim, and because the solution to obesity is to eat less, not to rebuild the world food system.
Notes
1. Also I hate the phrase "living with obesity" which is pathetic.

A Muslim faith leader calls for stronger moral leadership in the Middle East?

What is actually needed in the Middle East, and arguably lots of other places as well, is for most people to stop caring so much about other people's problems1. I've kinda said this already so I suppose I should expand a little. Our Writer writes We need moral leadership from religious figures on all sides: a determination to condemn not just the violence against “our own”, but also by those who claim to act on our behalf and this isn't true; what instead all these people should do is Fuck Off and remove the beams from their own eyes. The Middle East is notable for dictatorships and corruption (errm, with at least one obvious exception), expecting it to provide moral leadership is absurd.
In particular the idea that <people of religion X> should care deeply about <other people of religion X> is stupid tribalism that the world would be better without. But alas that kind of idea is not one that a "faith leader" is going to put forward. Even phrasing it as "messages which explicitly seek to acknowledge the “other”" is wrong. He is in favour of "diplomacy of the heart" but this is dumb; it is what leads to the "ambassador recalls, trade suspensions" which he condems; what is actually needed is heads, not hearts.
The poster children for this nonsense are the Houthi clowns, who despite being dirt poor and indeed only propped up by aid, nonetheless use their valuable resources to fire missiles into the sea. The West is, tiredly, knocking them back a bit; eventually we will get bored and knock them back further.
Speaking of corruption, South Africa comes to mind, and the recent ICJ case; wherein I find "The Court considers that, with regard to the situation described above, Israel must, in accordance with its obligations under the Genocide Convention, in relation to Palestinians in Gaza, take all measures within its power to prevent the commission of all acts within the scope of Article II of this Convention, in particular: (a) killing members of the group;...". This is obvious nonesense too; Isreal, as everyone agrees, will inevitably kill some civilians if operations continue; the only way to satisfy this would be to stop, which the court didn't order. If we read the judgement less literally to only mean "act in accordance with the convention" then that's just meaningless, because that obligation already exists.
Aid to Gaza and beyond at risk of collapse due to funding cuts, says UNRWA
Sez the Graun. And you'll find simimilar elsewhere no doubt. What's entirely missing is a thought that they are trying very hard to avoid thinking, and so blinkered are they that they have succeeded. The thought is "hmm, I wonder, just possibly, are there any other nations other than the West, just possibly some geographically close, who might have large amounts of dosh sloshing around that they could give? Nations that have, nominally at least, expressed great concern for the plight of the Palestinians". Another thought that is not being thought: though much of this goes to buy aid, much of it goes to salaries. But the Gazans receiving those salaries don't have a lot of other career options at the moment, so may as well continue working for nowt, or for promises - the Graun expresses concern about schoolteaching, for example.
Notes
1. You may perhaps think that I'm being hypocritical here. Not so! While I'm "happy" to spectate, I don't-if-I'm-honest really care much about these people's problems.

Priests and cannibals

Which is Why American cities are squalid, a subject on which everyone has an opinion. The piece, while wrong in its conclusions, isn't too bad, given its progressive-type biases (e.g. "A removal of resources for the majority, because of concerns over “misuse” by less than 1% of residents. I’m not saying those concerns aren’t well-founded" but if those concerns are well founded, you shouldn't have reflexively put scare quotes around misuse, you should have been honest enough to simply use the word). So after long revelling in the problems of having the homeless around, he notices that the system has no great trouble enforcing regulations at other times: "My favourite taco place was closed down twice during my short stint in LA, for bureaucratic reasons". And yet he fails to see the answer: the system, the police, are really bad at enforcing the law for people that won't obey, that have nothing to lose. Which in turn is part of the endless need for oversight; the failure to trust people on the spot. Which in turn is part of the awful modern reluctance of people to live with their choices. See-also Ban it harder! An unwelcome new trend in British politics in the Economist.

Sandel: Liberalism and the Limits of Justice

Even if it works to perfection in eliminating the influence of social contingencies, it still permits the distribution of wealth and income to be determined by the natural distribution of abilities and talents. Within the limits allowed by the background arrangements, distributive shares are decided by the outcome of the natural lottery; and this outcome is arbitrary from a moral perspective. There is no more reason to permit the distribution of income and wealth to be settled by the distribution of natural assets than by historical and social fortune (73-4).
The difference principle represents, in effect, an agreement to regard the distribution of natural talents as a common asset and to share in the benefits of this distribution whatever it turns out to be (101).The two principles are equivalent, as I have remarked, to an undertaking to regard the distribution of natural abilities as a collective asset so that the more fortunate are to benefit only in ways that help those who have lost out (179).Rawls believes the notion of common assets as embodied in the difference principle expresses the ideal of mutual respect deontological liberalism seeks to affirm.

Introducing Justapedia?

If I look at their current "Selected Contents" I find Outline of the American Civil War, Underwater diving, Poetry, Polar regions of Earth, Machine learning, Mormons, Philosophy and Adoption. Only one of those has had any updates since their import from Wiki, and that is a trivial update of a date in a flagging. That's powerfully unimpressive.
I haven't quite worked out when the import was done, but it looks to be around November 2022. Quillette gives the impression that JP is recent.
Why would you even bother doing this? Q talks about "Recent Wikipedia Controversies" but it is rather telling that issue number one for them is where the funding went, not anything to do with content. Next up is Wikipedia:Arbitration/Requests/Case/World War II and the history of Jews in Poland, which was a thing but not that exciting (I didn't follow it). They then come to what I think is rather closer to their hearts, Race and intelligence and how it is controlled on Wiki. They may have a point; I would whinge about a variety of other articles and topics, if I felt like it. But... it all seems too thin to sustain what they want.
Notes
1. Well that sounded nice and dismissive, which is what I intended, but then I decided on a quick skim. The core content policy doesn't seem to significantly differ from what they imported; and the 5 pillars also seem eerily similar to Wiki's version.

Richest 1% account for more carbon emissions than poorest 66%, report says?

‘Polluter elite’ are plundering the planet to point of destruction, says Oxfam after comprehensive study of climate inequality...
The richest 1% of humanity is responsible for more carbon emissions than the poorest 66%, with dire consequences for vulnerable communities and global efforts to tackle the climate emergency, a report says.
The most comprehensive study of global climate inequality ever undertaken shows that this elite group, made up of 77 million people including billionaires, millionaires and those paid more than US$140,000 (£112,500) a year, accounted for 16% of all CO2 emissions in 2019 – enough to cause more than a million excess deaths due to heat, according to the report.
The problem - apart from any quibbles with the doubtful quality of their analysis, which I suspect but am not very interested in - is that although they do their level best to present this as the 1% versus the 66%, they can't help notice that the 1% only emit 16%. So even after they've all been the first up against the wall after the revolution came, we've barely dented the problem. 84% of emissions remain - or at least they would, in the sort of static thinking that Oxfam do. Who is producing those emissions? You. Me. Our friends and colleagues. Everyone in the West. Well, everyone who isn't too dirt poor to do otherwise, really. Of course, different people emit differently, but it would need a much more careful analysis by less clearly biased people to produce something useful.
The Graun, which has the memory of a goldfish and the need to present things as though they were news, fails to point out that they've said all this before. Oh, duh, I've just realised: COP28 is coming up, hence the spam.

Lancet report: Heat stress wiped out equivalent of 4% of Africa’s GDP in 2022
But looking at some of their other pictures, you immeadiately see the problem: they're poor.
And so we immeadiately see that there are several possible solutions: reduce GW - but this isn't much of a solution, as the pic shows, even winding back three decades doesn't get you close to losing 0%; or stop being poor, which reduces the problem to negligible levels.
As a bonus, not being poor has other virtues, too. Perhaps you can think of some.
Oddly, CB doesn't much consider that option, instead perferring to whinge about "unjust transition". The reason they are poor is, of course, that their govt is shite; which is a consequence of the state of society, alas. But addressing the real problem is difficult, and entails saying things that people don't like saying nowadays.
BTW, somewhere - but I doubt I can find it now1 - was talking about ye traditionale "GDP declines with increasing T" stuff, and quibbling its stats. But never mind the details, the interesting bit was that even if you took the stats unquibbled, as well as the strong "hot countries" T-up-GDP-down correlation, there's a weak T-up-GDP-up correlation in cold countries. But because cold countries dominate global GDP, the overall effect of T up is GDP up (possibily not-stat-sigly). I'm reminded of that by the "* as percent" qualifier in the pic above.

Reporting of yer conflict

While we're on this, yer Beeb also say War crime claims: Volker Türk, the UN commissioner for human rights... Some context: The rules for war, which are spelt out in the Geneva Conventions, prohibit hostage taking, and say countries engaged in conflict "may not deport or forcibly transfer the civilian population of an occupied territory". But this isn't right. The actual text is Parties to an international armed conflict may not deport or forcibly transfer the civilian population of an occupied territory, in whole or in part, unless the security of the civilians involved or imperative military reasons so demand (my bold). Omitting the final qualifier is dishonest. By contrast, taking of hostages is unequivocally a crime.
I also have a hard time taking displacing people quite as seriously as the "war crime" people do. I'm sure these people don't want to be displaced, and neither would I, but it is a far less serious matter than deliberately killing civilians. I'd rather be displaced a hundred times than killed once.
Since I've been tasteless enough to use the image I have: I think the recent habit of prolonging wars is bad, and it is better to let one side win. Hence calls for ceasefires or pauses1 in the Israel-Hamas war don't make sense and will likely lead to greater suffering. Also, per Hobbes, you're only allowed to rebel if you have a realistic chance of succeeding.
Update: What is happening at Gaza’s al-Shifa hospital and why?
The Graun is fairly typical of the abysmal state of reporting. Hamas, and carefully selected doctors at the hospital, swear blind that there are no Hamas in there. Oooohhh no indeed not. And yet mysteriously the Israelis are finding it hard to get in. Why don't they just walk in by the front door? For the obvious reason: the Hamas folk inside would shoot at them. Why isn't this obvious to the Graun and a great many other people? Because the bias of their world view is so strong2.
2023/11/15: the stupidity of some of the old fat white dead men is... well, I'd like to say astonishing, but in fact I'll say entirely predictable. For example, from the FT: International aid agencies expressed alarm at the Israeli incursion into al-Shifa. “Hospitals are not battlegrounds,” said Martin Griffiths, the UN aid chief. “The protection of newborns, patients, medical staff and all civilians must override all other concerns.” FFS you clown: it is definitely not true that "The protection of all civilians must override all other concerns", you know this very well, its part of the "rulez" of war. But more importantly, once the Israelis are in there, the patients and staff and evacuees are all safe, as long as Hamas doesn't shoot them.
Al-Jazmagi has a go at answering "Why is Gaza’s al-Shifa Hospital so important for the Israeli army?" in a way that avoids the obvious answer: they propound the symbol-of-resistance type narrative. But this is a dubious idea, and even they are forced to answer "Hamas", although they do it right at the end in the hope you won't read that far.
Update: forced relocation
People in warm safe comfortable houses like the UN hate what they call forced relocation; e.g. this press release. But what do Gazans on the ground think? We don't need to ask them, because we can see the walls that the Egyptians are building, so the answer is clear: they would very much like to relocate.
Notes
1. As if to prove me wrong, The US says Israel will begin to implement four-hour military pauses in areas of northern Gaza each day to allow civilians to flee. But firstly, that text is deceptive: the "pauses" referred will not "begin", they have already begun, and had when I wrote the above. The US is saying that for its own internal political reasons, post-announcing something already happening as though it was a success of theirs. A brief apuse such as that, over a route out, does indeed make sense. Note that there isn't the least hint of a response from Hamas, who offer no corresponding pause in their own fighting.
