ERA40 Juli 1979, omega at 500 hPa
Dear Dr. Connolley,
with interest I have studied this figure.
I wonder why there is such a strong down-draft over the eastern Mediterranean. Is it a special feature of the large Indian monsoon anticyclone and if so why is it downwelling right there? Thank you in advance for any help on this. Kind regards, Hella Riede 18:33, 25 April 2012 (UTC) — Preceding unsigned comment added by 192.67.218.50 (talk)
Thermal underwear
Idealized greenhouse model, or the section below |
---|
May I ask a question? I stress that I am not trying to do any original research, but only want to improve the GW article by explaining what is fundamental to the AGW hypothesis. I don't think the current article really explains it very well. My question: I did some Googling and the Stefan-Boltzmann equation (or rather a derivative of it) seems to be fundamental. But there are two versions of it, as follows:
where alpha is albedo, S0 is a constant solar radiative flux (units W/m^2), T is temp in K, and sigma is a constant. The two sides of the equation both have units W/m^2. In the first equation e is 'emissivity' which is unitless and is the ratio of energy radiated by a particular material to energy radiated by a black body at the same temperature. I think of it as an 'underpants factor'. You have a black body throbbing with radiation, which will cool unless you keep it warm. So you put some underpants on it, to keep the cold out, i.e. stop it radiating so much. Hence CO2 and water vapour are like thermal underwear to keep the earth warm (if e is 100%, the temperature is about -18 deg C, for if you solve for e with current temperature, assume 15 deg C, you find e is about 60%). I am assuming e is constant whatever the temperature for exactly the same material, is that correct? In reality e will change as the material of the atmosphere changes (more CO2, or more vapour). In the second equation G is a number, units also W/m^2, which is a measure of the influence a factor has in altering the balance of incoming and outgoing energy in the Earth-atmosphere system. If you solve for G for 15 deg C, you get about 150 W/m^2. My puzzle is whether G is also constant, if for other reasons (e.g. change in solar radiation, change in albedo) the temperature changes. Intuitively it won't be constant. Why represent it this way? Apologise if I have misunderstood, and please correct any mistakes (I am quite new to this, but it is interesting). Again, I am not trying to do any research, just finding out some facts that could be put into layman's language and hopefully into the article. I think thermal underwear is a better analogy than greenhouses, e.g. HistorianofScience (talk) 11:52, 10 January 2010 (UTC)
Fine. Writing it all out is quicker than finding it, so... simplifying, the sun shines 4S units on the uniform earth (and since the area of a circle is 1/4 the area of a corresponding sphere the 4 drops out), which is a black body (forget albedo for the moment, it makes no real difference). The atmosphere is transparent to SW, and can be considered as a single layer not in conductive contact with the surface. There is no diurnal cycle, all is averaged out, all is in equilibrium. So at the sfc (with atmosphere) we have the following equation:
(the surface is black, captures all solar SW and transforms it into LW which it re-radiates) and G is the radiation from the atmosphere. Meanwhile, in the atmosphere,
(the atmospheric layer is totally opaque to the surface LW, is itself isothermal, and being a layer radiates both up and downwards). As it happens G = r(T_a)^4 but we don't care about that for tihs analysis. Hence, S + G = 2G, hence S = G, hence T_1 = (2S/r)^0.25. Meanwhile, in the absence of the atmosphere, we clearly would have T_2 = (S/r)^0.25. T_1 > T_2 (by a factor of 2^0.25) and (T_1 - T_2) is the greenhouse effect. William M. Connolley (talk) 21:02, 10 January 2010 (UTC) Also, this and the linked also refers, but is harder William M. Connolley (talk) 21:12, 10 January 2010 (UTC)

Blast from the past
Not to creep you out, but I was looking through old RfAs and I found this, from your second, and succesful, RfA. To the question of: How do you see Misplaced Pages in 2010 ?
OK, for what its worth, here is the rest: I see wikipedia continuing its growth and influence. The problems of scaling will continue: how to smoothly adapt current practices to a larger community. At the moment this appears to be working mostly OK. Problems exist with the gap between arbcomm level and admin level: I expect this to have to be bridged/changed someway well before 2010. I very much hope more experts - from my area of interests, particularly scientists - will contribute: at the moment all too few do. To make this work, we will have to find some way to welcome and encourage them and their contributions without damaging the wiki ethos. This isn't working terribly well at the moment. I predict that wiki will still be a benevolent dictatorship in 2010 - the problems of transition to full user sovereignty are not worth solving at this stage. William M. Connolley 20:36, 8 January 2006 (UTC).
Thought you'd be amused. Shadowjams (talk) 07:02, 12 January 2010 (UTC)
- Hmm yes. "Prediction is hard, especially of the future" as they say William M. Connolley (talk) 08:25, 12 January 2010 (UTC)

More thermals
All at Idealized greenhouse model it seems |

Thanks for your explanation which I am afraid I still don't really follow. I don't see how 'the earth heats the atmosphere' and 'the atmosphere heats the earth' can both be true.
| G ^ V Solar input. (4S ->) S | ---------------------------- Atmosphere. Emits G, up and down, thermal radiation. Absorbs S+G. ---------------------------- | | | V Solar straight through - atmos transparent, still S G V ^ S+G | ----------------------------- Sfc. Abs S(SW)+G(LW). Thus emits (S+G)(LW). Thus S+G = rT^4 Clear now? William M. Connolley (talk) 20:13, 12 January 2010 (UTC) Sorry, apart from the bit about not reflecting LW (that seemed picky, unless I misunderstood it), which of my claims was wrong? I said that the net outflow from earth to atmosphere has to be upwards. And that this outflow has to be exactly equal to the outflow from the atmosphere into space. Your diagram is incomprehensible. And what about Greenhouse effect where it says "Radiation is emitted both upward, with part escaping to space, and downward toward Earth's surface, making our life on earth possible." This is entirely wrong isn't it? It gives the impression that we are safe because only part of the radiation escapes to space, but the rest is trapped behind & keeps us snug and warm. The reality is that the net outflow from the earth has to be exactly balanced by the outflow at the edge of the atmosphere into space. Otherwise the atmosphere would keep on heating up until equilibrium was restored. HistorianofScience (talk) 20:31, 12 January 2010 (UTC) The unclearness of the diagram is the omission of the causality. You have the atmosphere radiating G downwards, e.g. Yes but where does the G come from? If we were to start with turning on the sun like a switch, at that instant there would be no G from the atmosphere. In which case the first thing to hit the earth would be S. Then earth would emit (not reflect) S. With no G. HistorianofScience (talk) 20:43, 12 January 2010 (UTC)
| 0 ^ V Solar input. (4S ->) S | ---------------------------- Atmosphere. At 0K. Doesn't radiate. ---------------------------- | | | V Solar straight through - atmos transparent, still S 0 V ^ 0 | ----------------------------- Sfc. Abs S(SW)+0(LW). At 0K. Doesn't radiate.
| 0 ^ V Solar input. (4S ->) S | ---------------------------- Atmosphere. At 0K. Doesn't radiate. ---------------------------- | | | V Solar straight through - atmos transparent, still S 0 V ^ G_T | ----------------------------- Sfc. Abs S(SW)+0(LW). Has warmed up somewhat, to T. Emits rT^4, call this G_T. So now the sfc has warmed up somewhat, so it is emitting G_T in the LW. Now the atmosphere isn't in balance: it is absorbing G_T but emitting nothing, since it is at 0K. So it will warm up. So it will start emitting downwards an warm further. And eventually we end up with the equilibrium solution William M. Connolley (talk) 21:47, 12 January 2010 (UTC) |

Dynamic topography
To William and his talk page stalkers:
Would you (ambiguously singular or plural) like to expand the portion of "Dynamic topography" that is about the oceans?
I am planning on doing some expansion of the solid-Earth-geophysics portion of that article (which currently covers both the dynamically-supported ocean elevations and topography due to motion of material in the mantle), but I think it would be a disservice to continue to ignore the ocean part. Ideally, we would have two separate standalone articles.
Awickert (talk) 17:26, 8 May 2010 (UTC)
- Good point. How analogous are they? I never got through reading Gill, so maybe now is my chance :-) William M. Connolley (talk) 18:29, 8 May 2010 (UTC)
- Well, I don't know anything about it in the oceans; in the Earth it is due to motion in the mantle that creates normal tractions on interfaces such as the surface, the upper/lower mantle discontinuity, the core-mantle boundary, etc. Since it is supposed to be about the motion of seawater, I can imagine how the physics could be identical, but I can't say for sure and about to head out the door: off to see a friend perform in Guettarda's favorite musical, Awickert (talk) 18:51, 8 May 2010 (UTC)
- Careful. That is pretty clear evidence of a Cabal, or possibly a Cadre William M. Connolley (talk) 19:22, 8 May 2010 (UTC)

- It's a good one - you should see it. Back to the topic: if it turns out that the underlying physics are the same, but just expressed in different media, I bet we could leave it at one article. If they are fundamentally different, then let's split. Awickert (talk) 01:21, 9 May 2010 (UTC)

Off-wiki meatpuppetry encouraged by arbcom! Transparency decried as disruptive!Bizarre. I guess the appropriate thing to do now is to keep all conversations about climate change off wiki.

WMC, you're screwed no matter what you do. The Arbitration Committee acted in bad faith throughout the proceedings (not all members, I hasten to add, but that was the net effect).

There was, of course, discussion of the case on the mailing list — though nowhere to the extent that some people imagine — but they were not substantive points but points of process; things like coordination of who was to write new proposals, suggested rewordings, exhortations to vote and get the effing case done. But, unlike what some people imagine, the actual nature of the decision gets very little attention on the list: you'll see the vast majority of that discussion and give-and-take on the decision page proper. (Coren) This is the most alarming thing I've seen in all the vast verbiage I've seen devoted to the case. I, like most rational people I expect, assumed that long delays during the proposed decision process, and the lack of workshopping and transparency in the discussion of the proposed decision, meant that, for whatever reason, the committee had decided to conduct their deliberations on the case behind closed doors. If this (bolded statement) is true and there were no substantive discussions on the decision behind closed doors, if in fact the only deliberations were the few brief exchanges that were visible on the proposed decision page, then I don't know what to say. I wouldn't go so far as WMC has done in questioning the veracity of Coren's assertion, I'll only say that to believe that the statement is not true is less damaging to ArbCom's credibility than believing that it's true, because believing that it's true means accepting that there were actually no deliberations of substance, which is not acceptable. Woonpton (talk) 17:45, 29 October 2010 (UTC)
But the most troubling point remains Coren's statement that "the vast majority of that discussion and give-and-take on the decision page proper." Since discussion on the decision page was perfunctory this demands the conclusion that there was practically no deliberation amongst the arbs regarding the merits of the case. In short, you can't have it both ways. You can't say on the one hand that there was "considerable discussion among the drafting arbitrators" and on the other that the discussion was mainly limited to the perfunctory comments we saw on the decision page. You guys aren't very good at this; if you care about retaining the sliver of credibility you have left you'll need to agree on a common story and stick with it.

Lest I forget William M. Connolley (talk) 19:41, 7 November 2010 (UTC) Time for a new strategyI don't know about you, but I think all this drama is unnecessary. My three-part plan:
Truth being, if most of the craziness in article space here ends up being a "flash in the pan" that is soon corrected without your help, then you might as well use your free time for fun and all is well (better, in fact: we've proven that you don't need to watch and defend the pages, and you can thank the arbs for your newfound free time). However, if lots of things have gone horribly wrong, then it will look like ArbComm's decision did not work out so well and WP is suffering quality-wise as a result. I say this because (1) I don't think that anything that you would do will make arbcomm revoke your topic ban come 6 months, and (2) regardless of wording, CC is beyond all bounds at the moment (and per #1 will remain so indefinitely). So I can see no reason to do anything but sit and watch. Awickert (talk) 00:42, 30 October 2010 (UTC)

Gurk: I've just noticed that Vogt et al. say M stars emit a large amount of their radiation in the infrared.

- Just looking. At first sight the edits are entirely reasonable. It seems plausible that L is R. T. Pierrehumbert - it is probably worth asking him to confirm that he asserts that (he just about has, but not quite explicitly). In which case I think the COI claims aren't very helpful: it isn't as if he is promoting some pet theory, and he would be a very valuable contributor to have editing wiki so best to be nice to him. Again, at first sight, the major difference between this and previous work appears to be using an ocean rather than a land-only planet; I don't know which is more likely. L suggests on talk that really this stuff isn't about Gleis but is common to all tidally locked planets; I started some wurbling in that direction at User:William M.

I have an impaired memory and it is helpful for me to have these kind of aide memoires. If you wish to extend that list of diff logs to include any other contributions listed by author without disparaging edit summaries or commentary you are entirely free to do so. But you are also free to ignore it or ask me to delete it. For my part of the favour please do and try harder; I can assure you, you have barely scratched the surface of my stupidity. --BozMo talk 08:14, 4 January 2011 (UTC)
- Thanks to you both. BozMo, I'm baffled: you've just willfully recreated a deleted page. How do you justify doing that? Since admins have no special rights (other than their tools) it is no more lgal for you to have that page than for me. Which implies that either you have sinned, or that I am free to copy it back into my user space William M. Connolley (talk) 09:02, 4 January 2011 (UTC)
- For what its worth I think context is everything. The arguments about the deletion of the page turned considerably around the PAs in the edit history and inference from how the entries came about. I did not recreate and move the page (or could have followed the convention of returning the page content to its owner) but thoughtfully created a page which preserves some of the content. On top of which for my part of the favour (the diffs on edits of mine) I am interested in whether the community is really going to declare me to be attacking myself. If my list gets deleted my next attempt would be to create a page with "things people say" as a title and include only my own diffs. To be honest it is a sad day for Misplaced Pages when an opinion on a diff is construed as a PA. The whole point is that you are allowed to dislike an edit, but not dislike the editor. --BozMo talk 12:41, 4 January 2011 (UTC)

PES
You and your talk page watchers are invited to look at User:Atmoz/photoemission spectroscopy and see if there is anything worth merging into Photoemission spectroscopy. I'll likely get around to it eventually, but the folk that go around nominating userpages for MfDs will likely find if before then. Thanks. -Atmoz (talk) 17:54, 12 January 2011 (UTC)

Record your cleanup
Hello. Could you please record your work progress at the newly created Misplaced Pages:Requests for comment/Jagged 85/Top edits and, if you haven't done so yet, at Misplaced Pages talk:Requests for comment/Jagged 85/Cleanup#Cleanup lists. The first link lists the most frequently articles edited by Jagged 85 by number of edits, the latter by total number of bytes added by him. As you know, keeping track of the cleanup effort is paramount to avoid double work. Thanks and regards Gun Powder Ma (talk) 01:36, 16 April 2011 (UTC)
Jagged 85 stuff
I missed the whole business with this, seems I was lucky. From what I gather from Tkuvho accusations being hurled toward me, he was abusing references? Anyways I thought you could take a look at Differential (infinitesimal) in its history section, Jagged 85 added some stuff that looks questionable to me and I thought you might know for sure at a glance. Thenub314 (talk) 06:26, 29 May 2011 (UTC)

WP:Scientific point of view
I've started to rewrite this, made an essay out of it and changed the argument. I argue that NPOV requires one to stick to SPOV on science articles, so sticking to SPOV on such articles is mandatory. If you have time, you can help expand it and perhaps it can later be proposed as a new policy. Count Iblis (talk) 03:29, 17 June 2011 (UTC)
Circumcision
At the moment, i am one of at least 8 editors who have complained about the current state of the circumcision article which was recently changed to sound much more pro-circumcision. There are a group of established editors who look like they are tag-teaming (Jakew, Jayjg, User:Avraham and User:Jmh649) supporting this pro-circumcision stance. Jakew, Avi and Jayjg have been edit-warring on this article with their pro-circumcision stance since at least 2007/2008. Do you have any opinions on this matter? Do you think an RfC or arbitration is appropriate? Thanks for reading. Pass a Method talk 10:56, 2 July 2011 (UTC)
- I would give up, you might as well persuade Conservapedia to take a balanced view on Global Warming. One editor in particular has owned that article for about six years and is a long term persistent pro-circumcision lobbyist, with occasional support. Even if you manage to get any kind of balance on the article, which would be impressive, you will find it erode into being pro cutting again over time. The resident editors will put far more time and effort into findly sources which support them etc than you will ever manage to, they are expert in Wikilaw too. You will encounter similar problems on other "optional surgery" kind of topics including cosmetic plastic surgery. Try to get a Germaine Greer perspective into Breast implant if you feel like a challenge. If you take it to the wider community the very strong USA bias toward pointless surgical intervention (financial incentive and knowledge converge) means you can never get consensus because there are always a few "looks ok to me" fruitcakes on the boards. Take it off your watchlist and concentrate on parts of Misplaced Pages where the improvement from effort is higher. (Circumcision is unusual in that generally the pro-surgery bias comes from practitioners with obvious financial incentives; with circumcisions the motivation of the resident team is less financial). --BozMo talk 15:27, 2 July 2011 (UTC)
- The lobby seems to advocate a bit more agressive pro-circumcision wording over the past month. Probably has something to do with the California vote to ban circumcision this year. Pass a Method talk 15:59, 2 July 2011 (UTC)

Clarifications
I'm sorry if I'm unclear--I'm not referring to arbitration cases but instances--but at this point it's all semantics. You aren't willing to accept responsibility for your actions, and so I don't support letting you off the leash you forged. Der Wohltemperierte Fuchs 15:42, 11 October 2011 (UTC)
- Sorry, won't do. You said "confirmation by WMC of the validity of all the complaints from previous cases". "cases" clearly means arbitration cases - it can't mean anything else. If you now wish to switch your wording to "instances" then you'll have to say what you mean by that. I've asked you which "cases" you mean, and I think you've evaded the issue. It looks to me like you simply made an error, but you're not prepared to correct yourself - hardly an inspiring example, indeed rather ironic, no? William M. Connolley (talk) 15:53, 11 October 2011 (UTC)
- (ps: for anyone else wondering, the other half of this conversation is . Perhaps I need to bold the "if I've left a message on your talk page, I'm watching it, so please reply there" in my edit notice William M. Connolley (talk) 15:57, 11 October 2011 (UTC)
- You aren't willing to accept responsibility for your actions - you are an impatient sort. I haven't answered you yet - I'm still trying to work out what you're talking about William M. Connolley (talk) 16:10, 11 October 2011 (UTC)
The actual diffs showing alleged problematic behavior by William are mostly similar to this incident today. ArbCom was in denial about the underlying problem, they totally ignored the fact that the probation system that was implemented before the ArbCom case started was a total failure (indeed, if it had worked, there wouldn't have been an ArbCom case).
ArbCom managed to devote a whole paragraph on the most irrelevant incident you can think of, William inserting comments on postings on his talk page, see here. None of the other issues gets so much coverage. Since it was eventually decided that William was allowed to do this, this was a non-issue anyway, but it is of course a totally irrelevant issue as far as editing in the CC area is concerned. Count Iblis (talk) 23:41, 11 October 2011 (UTC)
- I thought William was crazy for wanting to be unbanned, and told him so. In the unlikely event his appeal is granted he'll have flocks of admins, partisans, and partisan admins circling to look for the tiniest misstep. (Cooler heads than mine agree on at least this point.) Someone will haul him before AE for not saying "please" is an edit summary or similar nonsense and he'll get blocked, which will justify Arbcom's locking him back up and throwing away the key. Short Brigade Harvester Boris (talk) 00:39, 12 October 2011 (UTC)
- But to the point: do either of you know what DWF actually means by his talk of cases? Or, perhaps, what exactly is his confusion? William M. Connolley (talk) 08:23, 12 October 2011 (UTC)
- Let's do some mindreading. He wasn't an Arbitrator during the original case. Then let's look again at the final decision and see what someone who spends 20 seconds to read the findings about you would note. He would note the headlines, the links, because they have a blue color standing out from the main text, and phrases indicating bad behavior. The first headline is "William M. Connolley previously sanctioned and desysopped", the links refer to previous cases and the ominous words in the text that he would have noted in relation to these cases are "misused admin tools", "admonished", "restricted".
- The headline of the next section is "William M. Connolley has been uncivil and antagonistic", the text of the section doesn't contain much notable facts (the links are all numbers). So that section would make a lesser impact. And the last section about BLP edits probably won't make much of an impact at all. The headline "William M. Connolley's edits to biographies of living persons" isn't a negative statement, the text doesn't contain any links at all, and no alarming words like "disruptive" etc., phrases like "not..... appropriately neutral", don't sound very alarming.
- Clearly, of all these things that one would note in 20 seconds, the first section about previous cases stands out. Count Iblis (talk) 17:27, 12 October 2011 (UTC)
- DWF, as he explained, almost certainly meant "instances" when he said "cases." Please WP:AGF.
- case 1 n.1. An instance of something; an occurrence; an example: a case of mistaken identity.
- It is reasonable that you, also in good faith, had the arbitration cases foremost in mind, and therefore interpreted his use of "case" in the legal instead of common sense. Instead of arguing about this, why don't you just accept his explanation? The fact that you are making a mountain of this molehill does not bode well for your re-entry into editing on controversial pages. Yopienso (talk) 22:54, 13 October 2011 (UTC)
- William won't be allowed to edit BLP pages, so he'll be kept away from anything that is controversial about the CC area here on Misplaced Pages. The Wiki policies are a good enough barrier to keep the real world public controversy about the science of global warming out of the science articles, in case of the BLP articles this is not the case. Count Iblis (talk) 23:35, 13 October 2011 (UTC)
- DWF, as he explained, almost certainly meant "instances" when he said "cases." Please WP:AGF.

NLP
Would you be prepared to have another look at the NLP article? Encyclotadd still doesn't get the principle of OR and is now in breech of 3rr.

Economics of global warming
I've recently glanced at a few sections of Economics of global warming and frankly, I'm appalled. If it was my choice, I'd opt for blowing it up and starting from scratch, but it isn't my call. That leaves clean-up as an option, but frankly, I'd find cleanup of the Augean stables easier.
Any interest in pitching in?--SPhilbrick(Talk) 21:06, 23 April 2012 (UTC)
- Somehow I'd avoided having that on my watchlist. Certainly the intro reads very oddly. I've only skimmed the rest; I'm going to be busy for a week or so, but after that I'm happy to look more or help in any rework William M. Connolley (talk) 22:56, 23 April 2012 (UTC)
- Of course, there's no rush, and I have some real-life issues that will keep me occupied a fair bit. I don't think warming issues per se are the main problems. I intend to concentrate on some of the finance issues such as the jumbled discussion of risk, and the odd insertion of portfolio theory. However, when it comes to the poor handling of the Kaya identity, I trust you are more familiar than I with the proper presentation.--SPhilbrick(Talk) 00:12, 24 April 2012 (UTC)
Notability for websites
So whilst I was celebrating one of our websites winning the BBC One World "New Media Award" http://oneworldmedia.org.uk/awards/winners (sponsored by Google, and presented by Jon Snow, no less) I was wondering it this was enough to make it notable and hence worth its own article on Misplaced Pages. I am hopelessly conflicted (since I did the concept design) but perhaps you or a watcher might take have a quick think? Despite the award I guess verifiable content for the article if you exclude http://www.our-africa.org/about-this-site might be tricky to come by (there is quite a bit of material published as a Plone case study somewhere I think. --BozMo talk 18:49, 9 May 2012 (UTC)

Uptick in violent crime
Are you aware that a small increase in violent crime in the U.S. is being attributed to climate change leading to an early spring and to increased methamphetamine production due to the destruction of outdoor marijuana crops as a result of drought? According to a recent news story, "56 percent of the United States was in drought conditions as of May 8, almost twice the area compared to last year at this time, according to data from the U.S. Drought Monitor." Viriditas (talk) 08:41, 31 May 2012 (UTC)
- I haven't seen the violent crime bit, though the Fight Entropy blog has some useful stuff, e.g. http://www.fight-entropy.com/2012/04/temperature-and-generally-antisocial.html and the more important stuff about climate and conflict, http://www.fight-entropy.com/2012/03/carefully-interpreting-climate-conflict_30.html
- I don't find the stuff from Lester Brown in your link convincing, though. "Our entire agricultural system is geared to the stable climate conditions we've enjoyed for the last few thousand years. And that's changing," is dubious - there have been some large changes over those 2kyr. And the land-grab stuff is similarly dodgy William M. Connolley (talk) 11:19, 31 May 2012 (UTC)

- Sorry for the delay replying. As you might be able to guess, this is because I don't have a good answer to give. They are clearly unusual in the context of the recent few decades past, but quite possibly not in the context of the longer term. More interesting still is whether they will continue.

By which I mean, for every "its warm" story you'll find another "its cold" story.

Indian mathematics
Hello, I am a user very active in the Good Article nominating system. I often look and scout for articles that could pass as GAs. I was sifting through WikiProject Mathematics, and found this article. You seem to be the editor who has has the most recent edits done, and I was wondering, do think the article is ready to go under a GA review. If so, Great! If not, what could be done to improve it.

It looks to me to have problems, semi-nationalistic ones, in over-promoting the role of IM and failing to set it in its correct place.

(Change of subject) Did you clear that picture up there with Larry Sanger? Apparently he has teamed up with Fox News to protect us... --Guy Macon (talk) 11:34, 25 June 2012 (UTC)
- I discussed this on a blog a little while ago, http://ocham.blogspot.co.uk/2012/05/what-should-we-do-about-wikipedias-porn.html. I don't think I convinced anyone over there. Oh... you're referring to my edit-notice pic, aren't you? I thought you mean my current facebook pic... hold on... William M. Connolley (talk) 12:07, 25 June 2012 (UTC)

(Note to talk page stalkers: you have to click on the edit button to see the picture I am talking about). Nice comments on that blog, BTW. Alas, you can't use reason to change a person's mind when they didn't use reason to arrive at their position in the first place. --Guy Macon (talk) 12:48, 25 June 2012 (UTC)
- For most people, nudity and swear words have their place and time. I was at a party once, and we were all having a great time, when out of the blue, some guy comes up to a group of us, takes his "member" out of his pants, and starts swinging it around, showing it to everybody. Now, nobody wanted to see that. However, if he had taken off his clothes and jumped in the pool, nobody would have even noticed (and in fact a very beautiful, well-endowed young lady did just that, and hardly an eye turned). So, I think the main objection that is reasonable, is context and distance. For example, if your child is doing a book report on Cleaveland, you probably don't want them have to read about a Cleaveland steamer (or try to explain it to them). For me, this can be fixed by correcting poor search terms and redirects, and I think the Sanger & Misplaced Pages is Porn crowd do have a point when they say it is easy to access the "wrong" material during a search. But, the answer isn't censorship, it's about finding new and better ways to optimize the search and retrieval process and to direct users to the content they are actually searching for instead.

- It's only weather, and NOAA can't even assure growers that there is an end to the drought in sight so obviously their models are no use. Bit worrying that it is starting to "leave hungry countries in the Middle East and elsewhere scrambling" – chocks away, bandits at 12 o'clock etc.? Fortunately Tom Vilsack, the US agriculture secretary, is considering a rain prayer or rain dance. . . . dave souza, talk 06:39, 20 July 2012 (UTC)
- "Temperatures on land were the warmest ever recorded" in the U.S. for 2012. But not according to Ron Johnson, Republican United States Senator from Wisconsin:
A global warming skeptic, Johnson said extreme weather phenomena were better explained by sunspots than an overload of carbon dioxide in the atmosphere, as many scientists believe. "I absolutely do not believe in the science of man-caused climate change," Johnson said. "It's not proven by any stretch of the imagination." Johnson, in an interview last month, described believers in manmade causes of climate change as "crazy" and the theory as "lunacy." "It's far more likely that it's just sunspot activity or just something in the geologic eons of time," he said.

Also, here's how things will actually play out, at least in the U.S.: climate change → more frequent and severe droughts → food prices skyrocket → consumers have less disposable income → people demand that we loosen regulations on oil companies so gas gets cheaper → gas does not get any cheaper but carbon emissions increase → return to beginning of this sentence.

- Oh, sorry, that was me getting the two cases confused. So the one Tamino was talking about was the 1/3^13 one, for which ignoring auto-correlation turns out not to matter too much, because its small anyway (because the spatial region is just the US). The one V mentions - the 327 one - is talking about global temperature, where the autocorrelation is much higher, so 1/2^327 is badly wrong as a calculation. But I suspect the same underlying answer applies - that when you do take account of autocorrelation, the chances of it happening remains very low. But it would be good to get these things correct.

I've already been asked about "all the ice in Greenland melting" (!!), and can only wonder how soon this palpable untruth is cited as evidence of "warmer" deceitfulness. The warm, brownish colors on the NASA image certainly suggests bare rock, and the new media don't seem to be dispelling the notion that all of the ice sheet is gone. Lest any passers-by get confused, we should point out the "Greenland-melt" is only of the surface of the Greenland ice sheet. The bulk of the ice sheet is still there. Else we would be seeing several meters of sea-level rise. ~ J. Johnson (JJ) (talk) 17:32, 26 July 2012 (UTC)
- My reading was that it was pink for warm, meaning surface melting and a change in albedo. Bad enough, haven't yet seen any claims it was deep melt. . dave souza, talk 17:36, 26 July 2012 (UTC)

Younger Dryas impact hypothesis
You commented on a dispute over the Younger Dryas, so perhaps you could give your view on one over the Younger Dryas impact hypothesis.

Bees and wasps
This year has been an extraordinary year in that there were no wasps. Normally all the apple and plum trees in the garden are swarming with them.

Article on sea ice
Hi! You have taken out illustrations from the article on sea ice. Is it because they were too big? They can be reduced in size - I find them very helpful for understanding what sea ice is about. As for the table, the source was indicated - why is this not allowed? I am a new contributor, and am open to criticism (but I would like to understand) --Lusilier (talk) 19:43, 17 December 2012 (UTC)

- Thank you for your comment. If it's ok with you, I will put it back in smaller size (and will do the same to some of my other contributions). It took me a while to draw that diagram - it is based on extensive reading, notably of the sources in the reference section, and my own experience - I make a living working with sea ice (though I don't know if this should matter in a wiki).

BP structure suggestion
Hi William, I have recently put forward a suggestion for a new structure for the "Environmental record" and "Accidents" sections of the BP article. This is something I had originally proposed in December, when it was overshadowed by discussion of the article's introduction. Beagel, Petrarchan and Martin Hogbin have commented so far, however none have made the changes I suggest. (Currently Beagel and Petrarchan are busy on the Deepwater Horizon oil spill page.) As you have been involved with discussions on the BP article previously, I would like to hear your thoughts on the structure I propose and see if you would be willing to put this into place. Thanks. Arturo at BP (talk) 16:53, 10 January 2013 (UTC)

Some thoughts: the AM-GM-HM inequality states that, for all positive integers n, and provided that x1, x2, ..., xn are all positive reals, the arithmetic mean is greater than or equal to the geometric mean, which is in turn greater than or equal to the harmonic mean, with equality ocurring when x1 = x2 = ... = xn. In algebraic terms, this means that:
It immediately follows that the n = 4 case for positive reals a, b, c, and d is:
- (1)
The n = 4 AM-GM result can be proven by first expanding to establish that and then, by taking and , obtaining:
- and noting that and
- , establishing (1) as expected.
Now, taking the n = 4 case but defining x1 = ab, x2 = bc, x3 = cd, and x4 = da, we find:
- (2)
I had planned to put (1) into (2) to obtain the required expression abcd(a + b + c + d) but the inequality goes the wrong way, so I'm stuck as all I've established is that both sides of the original inequality are greater than or equal to but maybe this will be helpful for someone. EdChem (talk) 04:00, 24 January 2013 (UTC)
- It is not a research problem it is extension homework set for a thirteen year old which therefore can be done with basic algebra. I have given up but am waiting for the teacher to go through it with her. I assume the problem must have come from somewhere (possibly a past BMO2 paper if that means anything) but I could not find it and searching for equations online seems a tad tricky. For what its worth I think I have seen a three variable version of this with cubes but I cannot remember how to do that either. I even tried checking it was actually true for a scatter of variables, but it does seem to be true. --BozMo talk 08:40, 24 January 2013 (UTC)

- Got the answer home now. Four lines long but basically unguessable in my view; it relies on an AM-GM looking not much like the equation and its three cyclic permutations all being added up to give the equation shown.

Okay, educate me if you have the time. I'm missing something
Where am I going wrong (I'll bullet my observations, decisions)? I read Chapter 6 of AR5 WG1 technical chapter (pre-release) and
- there is broad discussion of atmospheric GHG, Well-mixed GHG's, etc, etc.
- and the sources of those gases
- They come from a a few principle anthropogenic causes such as fossil fuel burning, cement factories and land use change.
- They appear to provide the source for RCP pathways for CMIP5 models that are used with various drawn and quartering of maps to represent different topology, etc..
I then read chapter 8
- which is the physical underpinnings where the model is run and analyzed.
- chapter 8 concludes anthropogenic WMGHG are the primary cause of warming and the net forcing is positive.
- it concludes that ocean acidification will continue due to these GHGs
- land use change as a human activity is as likely as not to contribute to net positive forcing (i.e. the trees in the peat experiment).
- albedo measurements are much higher confidence since AR4.
- there is low historical confidence that land use change contributed to a net positive forcing.
- there is low confidence that land use changes will contribute to a net positive forcing in the future (and was slightly negative in the past decade)
I get that land use change added CO2, and on the whole that will contribute to things like carbon uptake of the ocean, ocean acidification, climate response time, etc. But I can't find where the connection of land use change is made to temperature (i.e. "global warming" in the opening statement of Global warming. GHG emission is pretty straightforward. Albedo is pretty straightforward. They have a dodgy "it's complicate hydrological interaction, so don't ask" part. And overall low confidence to all of it but somewhere centered around zero as it relates to a forcing.
What am I missing if I may ask? --DHeyward (talk) 00:26, 16 January 2014 (UTC)
- I'm not entirely sure what you're missing. Land use change contributes to GW indirectly, because it contributes GHG's that lead to warming. But the *direct* effect is less clear (I haven't looked myself, but if you say "is as likely as not" that will do for now).
- So when the GW article says "IPCC says that the largest driver of global warming is carbon dioxide (CO2) emissions from fossil fuel combustion, cement production, and land use changes such as deforestation" that fits perfectly; and I can't see why you're objecting. That statement *doesn't* say "IPCC says that the largest driver of global warming is carbon dioxide (CO2) emissions from fossil fuel combustion, cement production, and direct radiative effects from land use changes such as deforestation". You seem to be reading in the part I've bolded, but it isn't there William M. Connolley (talk) 08:40, 16 January 2014 (UTC)
- "is as likely as not" is from the AR5 chapter 8 - and they clumsily say a few different ways because the science a bit inconclusive. My reading is/was that, yes, CO2 is the radiative forcing that dominates global warming (with some up and comers like methane). That's a physical phenomena well established. Fossil fuel burning, cement production and land use change are human activities, though. If I test the human activity against the hypothesis that it causes global warming (increase in global mean surface temperature, Bayesian if you will), I get from the AR5 literature:
- fossil fuel burning activity -> very likely contributes to warming, passes criteria
- cement production -> very likely contributes to warming, passes criteria
- land use change -> as likely as not to contribute to warming due to competing physical effects, fails criteria as its independent of warming
From they way I read it, had land use change not occurred, the temperature increase would be approximately the same and the activity link to global warming is missing. Certainly the link to GHG's is there and the other effects, but not "Global warming." With or without land use change, the net radiative forcing is still positive and still about the same. So my objection is stating how the activity of land use change relates to global warming, not CO2. Certainly it is accurate to say land use change adds CO2 to the atmosphere, the ocean effects, long term trends, etc. But "global warming" doesn't seem to pass the hypothesis - since if land use hadn't changed, the IPCC says the temperature through net forcings would be relatively unchanged. This seems to be what Chapter 8 in the technical side is saying. Total radiative forcings are positive to support GW, but land use change isn't an anthropogenic cause of that change. This is what they are proposing starting in 8.3.5. I don't get the impression they are talking only about albedo, but rather the albedo numbers have firmed out so the net radiative forcing of GHGs and albedo is now 0 (confidence increase from AR4.) Here's what I thought were the relevant paragraphs that combine RF and WMGHGs. I bolded the statement that I thought disassociates the human land use change from global warming (not just albedo or WMGHG concentration but taken as a whole).
Am I making sense? Am I missing something else where testing the activity of land use change to the change in temperature is not the proper test?
Deforestation has a direct impact on the atmospheric CO2 concentration, and therefore contributes to the WMGHG RF as quantified in Section 8.3.2. Conversely, afforestation is a climate mitigation strategy to limit the CO2 concentration increase. Several authors have compared the radiative impact of deforestation/afforestation that results from the albedo change with the greenhouse effect of CO2 released/sequestered. Pongratz et al. (2010) shows that the historic land use change has had a warming impact (i.e., greenhouse effect dominates) at the global scale and over most regions with the exception of Europe and India. Bala et al. (2007) results show latitudinal contrast where the greenhouse effect dominates for low latitude deforestation while the combined effect of albedo and evapotranspiration impact does at high-latitude. These results are also supported by Bathiany et al. (2010). Similarly, Lohila et al. (2010) shows that the afforestation of boreal peatlands results in a balanced RF between the albedo and greenhouse effect. Overall, because of the opposite impacts, the potential of afforestation to mitigate climate change is limited (Arora and Montenegro, 2011) while it may have undesired impacts on the atmospheric circulation, shifting precipitation patterns (Swann et al., 2012).
8.3.5.6 Conclusions
There is still a rather wide range of estimates of the albedo change due to anthropogenic land use change, and its RF. Although most published studies provide an estimate close to –0.2 W m–2, there is convincing evidence that it may be somewhat weaker as the albedo difference between natural and anthropogenic land cover may have been overestimated. In addition, non-radiative impact of land use have a similar magnitude, and may be of opposite sign, as the albedo effect (though these are not part of RF). A comparison of the impact of land use change according to seven climate models showed a wide range of results (Pitman et al., 2009), partly due to difference in the implementation of land cover change, but mostly due to different assumptions on ecosystem albedo, plant phenology and evapotranspiration. There is no agreement on the sign of the temperature change induced by anthropogenic land use change. It is very likely that land use change led to an increase of the Earth albedo with a RF of –0.15 ± 0.10 W m –2 , but a net cooling of the surface — accounting for processes that are not limited to the albedo — is about as likely as not.

- Ah, now I see what you're trying to say. In that case, there are a couple of answers: (a) this is somewhat difficult to interpret language from an unpublished report that explicitly says "Do Not Cite, Quote or Distribute". So, you can't use it as a source for anything (of course, if you have the energy you could chase up all the refs that it backs that up with, and you can use those); (b) so on the whole I'd say we could make sure we agree on the issue (which I'd say was "land use produces a +ve RF from CO2, and a negative RF from albedo, and these ~balance, perhaps") in anticipation of the text becoming citable (though of course it may change); (c) if we then return to the text in the lede we find it still true, even if we admitted the draft text, because "IPCC says that the largest driver of global warming is carbon dioxide (CO2) emissions from fossil fuel combustion, cement production, and land use changes such as deforestation" says (1) "IPCC says that the largest driver of global warming is carbon dioxide (CO2) emissions" (which is true); and (2) these CO2 emissions are "from fossil fuel combustion, cement production, and land use changes such as deforestation" (which is also true). You could possibly complain that this truth isn't quite what you might expect it to be saying. I'd say that the relatively subtle (and at this point uncertain) distinction that land use changes also have a probably negative RF is too subtle and not important enough for the lede William M. Connolley (talk) 12:13, 16 January 2014 (UTC)
- Plus, assuming for the sake of argument that land use albedo changes has indeed canceled land use GHG changes, we have to add so far. There is no reason to think there's a fixed ratio there. And for that matter, burning fossil fuels has a negative forcing component too, in terms of sulfates and if I remember correctly high atmospheric particulates. To expand on a prior remark, I'm all for striving for FA quality treatment of the components of net forcing at Attribution of recent climate change and adding something more in the body of the article. The lead sentence being quibbled over is about the largest contributor to positive forcing - GHG - and land use contributes. If you're still not convinced, t will take heavy hitting secondary sources to overcome IPCC's nutshell bubble on point. NewsAndEventsGuy (talk) 12:29, 16 January 2014 (UTC)
- @WMC, yes it makes sense though I find it ironic that the SPM cites the source that must not be named. It would not make it easier to add the individual sources when the full report is weeks away. For land use changes, it seems "when" and "where" are relevant but the article doesn't make that demarcation. Currently land use change seems to be an order of magnitude less than the top two CO2 drivers. It's also a declining component in both raw tonnage and percentage (at least what I read in atmospherics area) for all 4 RCPs. Land use change goes back quite a ways though and inertia/load on ocean and flora/fauna reuptake might be interesting. I'd also think deforestation as a single element of land use change might need clarification or even replacements depending on rice paddies and such. Or just removed if it's really a single fraction an order of magnitude lower. --DHeyward (talk) 21:08, 18 January 2014 (UTC)
- @NAEG, I'm not sure what you mean by "FA quality treatment of the components of net forcing" but presumably you think they ought not be treated in the article about global warming? Forcings are derived as part of the modeling process. Much simplified, integrating over time and area of all the forcings yields a temperature. Usually, global warming is expressed in terms as anthropogenic activities. In that sense, we would have net sums of the forcing of the activity and measure it against the hypothesis that it causes warming. The sulfates from fossil fuel burning would be part of the net forcing derived from the activity of burning fossil fuels. Those sulfates would be treated much differently than volcanic sulfates. The argument I presented is that each activity is tested against the hypothesis that it causes warming, not each chemical. Breaking it down by chemical component is rather difficult argument to make because it's the net sum of the activity. "Global warming is caused by GHGs emitted by activityX , activityY, and activityZ." It stands to reason that each activity, separately, as a sum of it's own forcings, pass the statistical test for global warming.
- It's probably more obvious why we should state it that way if, instead of global warming, we use mitigation for illustration, (I am making up this scenario absurdium using sulfur as cooling forcing) "Global warming is mitigated by sulfur emitted by volcanic eruption and by burning high sulfur content diesel fuel and coal" would be an inference that is not supported and I suspect objectionable even if sulfur is a mitigating chemical and diesel/coal is a primary source of atmospheric sulfur (connecting the dots like the lead sentence does). We would want to test each of the activities for mitigation before asserting a component they produce is mitigating. Breaking it into two sentences. "Global warming is mitigated by sulfates" and "Sulfates are emitted by volcanic eruption and by burning high sulfur content diesel fuel and coal" might both be true as separate statements as well, but again it's problematic to imply that sulfur from diesel fuel and coal would be stated as mitigation if the activity was net warming. It's the same logic/criteria for asserting an activity for causing global warming as it is for global warming mitigation. The story is net effect of human activity and that shouldn't be lost in roles of individual chemicals and the net effects. Therefore statements that start with testable hypothesis (i.e. causes of global warming, mitigation) and then list activities need to make sure the activities meet the testable criteria, not just one of the components. I don't think this is inconsistent with the sources. --DHeyward (talk) 21:08, 18 January 2014 (UTC)

Opinion on very recent sunspot/stratosphere/trade winds/la nina/pause??
Have you looked at any of this recent stuff? As far as I can tell, the bleeding edge "trade winds" and the "extended La Ninja since 1998" traces back to stratospheric warming caused by low sunspots as it interacts with stratospheric ozone. Xie managed to put numbers on it with SST's I think but it's a few years old as non-numerical theories. From what I recall, low sunspot cycles correlated to large trade winds and La Nina. This seems like a lot of handwaving (especially as solar variance larger than a single representative cycle is not modeled as a relevant variance and a 1st order ħν energy doesn't appear convincing). A specific frequency/cycle dependent reaction with ozone maybe? Anyway, my interpretation is that it's a largely a message reaction to the "hiatus/pause" rather than a rigorous conclusive proof. Are you keeping up with any of this stuff? (BTW, CMIP5 was conceived as a decadal sensitive model, though the difference over CMIP3 is beyond my learning. Is the "nah" edit summary the QED term for Jan L. A. van de Snepscheut's null hypothesis "In theory, there is no difference between theory and reality. But, in reality, there is." :) ) --DHeyward (talk) 06:05, 14 February 2014 (UTC)
- I think at the moment I'd go for "there isn't really any pause". See for example http://tamino.wordpress.com/2014/02/06/cowtan-way/. England et al. don't quite agree with me (http://www.nature.com/nclimate/journal/vaop/ncurrent/full/nclimate2106.html) but pfft, what do they know? I'm not sure where you get the stratospheric connection; cn I think William M. Connolley (talk) 14:41, 14 February 2014 (UTC)
- Stratosphere temp -> La Nina states "During a La Niña event, the troposphere cools down while the lower stratosphere warms over the tropics." I think I read a paper by Stefan Brönnimann that made a cleaner reference but can't find it at the moment. Here's the Solomon et al piece on stratospheric water vapor. Dessler et al makes the connection of troposphere temp to water vapor in stratosphere. There is also the stratosphere temp over time being inverted to surface temperature except when volcanic sulfate releases warmed the stratosphere. Then there is this Lon Hood presentation (page 13,20) which makes another connection to stratosphere and a "La Nina" like condition that is observed near solar maximum (there's other papers too). Are they just converging on the same observable from different topical areas or is it me? I'll find better ones as there are more recent ones that seem all connected. --DHeyward (talk) 18:04, 14 February 2014 (UTC)
- And trade winds during la nina are unusually strong. We're just passed a solar max or in a really long one so strong trade winds shouldn't be surprising if the Hood et al papers are correct. I'm inclined to agree that the climate has not stopped or paused in warming. I'm all for understanding mechanism but some of these recent papers that get press (and pushed) appear only to be rebuttal papers for sceptics. They get blown way out of proportion to their contribution to knowledge and if they don't hold up over time, they are used as fodder. --DHeyward (talk) 19:16, 14 February 2014 (UTC) --DHeyward (talk) 18:51, 14 February 2014 (UTC)
- BTW, thanks for the Tamino link. I saw that column added to "Warmest years by dataset" but that source only commented that it was a better way to interpolate sparsely monitored arctic areas but didn't explain how. I'm not particularly fond of defending the models with a simple linear regression +/- 2 sigma. While accurate, it's not complete. It would be nice if the ensemble hindcasting results could generate data with a correlating mean and variance if it's accurate over that time scale (which is advertised that it is). If it was Monte Carlo we could compare the two populations (simulated vs. measured) to see if they are the same population but I don't think the ensemble is set up to generate a population that could be compared. As I understand it, the problem is internal variability is constant over all time scales while other sources of variance increase over time so over the short time span it's more sensitive to internal variability. --DHeyward (talk) 18:51, 14 February 2014 (UTC)
Cleaner version (this tongue-in-cheek rigor, BTW).
1. Solar cycle 24 is currently around it's maximum sunspot number. SC24 is a drawn out max typical of low sunspot count years. Solar maximum occurs around when magnetic field of the sun is weakest, collapsing and reversing. TSI is largest at solar max. See also Solar cycle#Short-wavelength radiation.
2. Stratospheric ozone is largely created from the short-wavelength radiation which is largest at solar max.
3. Ozone and NOx creation/loss and transport affect global circulation patterns
4. Solar max and la nina-like conditions correlate well.
5. la nina conditions generate very strong trade winds
6. Strong trade winds are responsible for the "pause" Tollefson in Nature commenting on Xie and other pause papers

- Hmm, well, I haven't looked at all the details. Unravelling the mechanism of ENSO is interesting. But its also hard work, and I don't have to do that stuff any more. I think you'd be surprised how uninterested most climate-types are in the "pause" stuff; the action there is mostly in the political domain.
