Wikimania and TPWs[edit]

For reasons best known to itself (but no doubt excellent), Wikimedia Deutschland has seen it fit to give me a scholarship to attend Wikimania. I will be in Hong Kong from Tueday way to early to Sunday way too late (August 6th to 11th). If anybody reading this is there, I'd be happy to meet some of you in person. My preliminary plan is here. --Stephan Schulz (talk) 16:48, 25 June 2013 (UTC)

Thank you very much!![edit]

Re: Bradley Manning Edit[edit]

I saw you reverted my edit, where I removed the template Mos-Tw. I'm convinced it doesn't belong and further, is a BLP violation in this case. Bradley Manning is a man, legally, verifiably and biologically, so having a template on this page stating "Because this article contains material about one or more trans women " is making an inaccurate statement supported by no verifiable references (and it could be construed as being a violation of BLP ). Since the template can't be changed (that brings it's own problems) better to remove it out of the talk page completely.

That being said IF Bradley Manning goes Christine Jorgenson and legally changes his gender and his name, then we can put the MOS-TW right back in , as it would be appropriate. So, what's your take ?  KoshVorlon. We are all Kosh ...  17:04, 11 September 2013 (UTC)

My take is that WP:MOSIDENTITY clearly implies that we assume the latest expressed gender self-identification of a person, regardless of where bits of the body are dangling (or standing - there's a happy thought ;-). So while Manning's biological sex might be male, her gender, as used on Wikipedia, is female, and she is a woman. Hence the template is not a BLP violation, as far as Wikipedia is concerned. --Stephan Schulz (talk) 17:47, 11 September 2013 (UTC)

I hear you loud and clear, this is :
Disputes over how to refer to a person or group are addressed by policies such as Verifiability, Neutral point of view, and Article titles where the term appears in the title of an article which implies that verifiable information needs to be used over what that person happens to prefer. I realize that when there's no disupte, per MOS:IDENTITY , the persons preferred name, title, etc... can be used, but , see , it's disupted, so V, NPOV and BLP take effect and per that, we refer to the person the way they're referred to in our reliable information. So, I respectfully submitt that calling Bradley Manning a trans-woman is a BLP violation. YOu follow ?  KoshVorlon. We are all Kosh ...  19:34, 11 September 2013 (UTC)
Read further. "Any person whose gender might be questioned should be referred to by the pronouns, possessive adjectives, and gendered nouns (for example "man/woman", "waiter/waitress", "chairman/chairwoman") that reflect that person's latest expressed gender self-identification." Manning's preference is verifiable, according to WP:V - see e.g. [1],[2]. --Stephan Schulz (talk) 20:31, 11 September 2013 (UTC)
I hear you. You want Bradley Manning's article to comply with WP:V. No problem at all, you and I both agree that it should. Your first source identifies Manning as Bradley Manning and never uses a pronoun (neither male nor female).
The Guardian uses all female pronouns, however, the Guardian is a tabloid magazine and fails reliability.
That and MOS:Identity is disupted and therefore cannot be used a criteria. Still looks like he's verifiably a man, is being called Bradley Manning and is still legally, biologically and reliably male.  KoshVorlon. We are all Kosh ...  21:06, 15 September 2013 (UTC)
I'm sorry, but The Guardian is not a "tabloid magazine", either in the literal sense (it's printed in Berliner) nor in the figurative sense. It's certainly a reliable source for Wikipedia, and has been accepted as such on many occasions. As you correctly point out, the WaPo article uses the name for identification, but does not take a side. Here is another WaPo article discussing that reliable sources are conflicted about the use of pronouns. And here it uses the female form itself. Another example (via the AP) is here. WP:MOSIDENTITY has been clear for a long time. And even the "disputed" tag makes it clear that "Until the dispute is resolved by consensus, it is recommended that the guideline remain in effect" - not only can it be used, it is even recommended to use it. --Stephan Schulz (talk) 21:42, 15 September 2013 (UTC)

1942 German textbook[edit]

Hi, a professor posted this for us today to show how governments write school textbooks. Don't know if you're curious about this or if you could use it in an article, like social Darwinism or Nazism or such. Yopienso (talk) 08:24, 21 November 2013 (UTC)

Hi Yopienso! Thanks. Per Francis Bacon, I'm interested in everything (see my user boxes ;-). Nazi propaganda is not one of my particular interests, but I'm always happy to have a look at quirky and weird things, if only for delectation! --Stephan Schulz (talk) 09:01, 21 November 2013 (UTC)

Berkeley Earth[edit]

Hi, Stephan. Might you have a chance to take a look at my edit request at Talk:Berkeley Earth? I have a COI and don't want to do much with the article directly. Thanks for any help. Dragons flight (talk) 04:42, 6 December 2013 (UTC)

I'm in South Africa right now, so net access is irregular and the beach is calling (and my girl friend is making the call urgent ;-). But I'll take a look tonight. --Stephan Schulz (talk) 08:06, 6 December 2013 (UTC)
Beach? ... 22 �F and 6+ inches of white fluffy stuff here ... envy. Anyway I've applied the suggested changes, tweak/redo as needed. Enjoy the beach ... Vsmith (talk) 16:33, 6 December 2013 (UTC)
You're in the wrong field. I'm up to speak at LPAR 19, and we came two weeks early. Our 22 is in Celsius, and in the shade - the sun is a different matter entirely! On the "if you have lemons" motto, I suggest you take up snowboarding. Anyways, I saw that you and Vsmith have done the updates, read over it, and it looks good. --Stephan Schulz (talk) 16:50, 6 December 2013 (UTC)

An apology.[edit]

Hello Stephan, this is Keeby. I just wanted to apologize for my rude and asinine behavior on a certain talk page a few months ago. I started an edit war and I didn't have any references or sources (at least not any good ones) to back up my claims. I hope you can forgive me on that regard. Keeby101 (talk) 20:09, 16 December 2013 (UTC)


I also have changed my ways since then. Keeby101 (talk) 20:09, 16 December 2013 (UTC)

Good for you. I'd already nearly forgotten the issue - I certainly don't hold a grudge! In my 10 years or so I have seen plenty worse ;-). Have fun editing. --Stephan Schulz (talk) 21:19, 16 December 2013 (UTC)

What is the next step? John Calvin RfC Closure[edit]

I submitted a request for an uninvolved editor to close an RfC. But what happened was a person who self-describes as a Reformed Presbyterian (i.e. an admirer of Calvin) closed the discussion with no change to the article, which I had flagged as having a NPOV problem. The votes were 50/50 with all the people describing themselves on their talk pages as Calvinists (Reformed), voting for no change, and anyone not having a Calvinist background voting to change the section of the article to improve NPOV. I don't believe an editor who is a Calvinist (or an anti-Calvinist) should be deciding how to close a contentious POV discussion. Please advise me what the next step should be. I don't know how to request a review of this closure. Am I allowed to revert it?

Hi Mark. I understand your concern, but I'm currently at a conference far far away, and about to get back on the plane to still far away (though closer ;-). Thus I have not and cannot spend enough time on Wikipedia to have an informed opinion and state it well enough to matter. If the situation is not resolved after Christmas, I will take a look. --Stephan Schulz (talk) 05:50, 20 December 2013 (UTC)

You might be amused[edit]

by Wikipedia:Arbitration/Requests/Case - an edit by EyeTruth[3] is used saying that " I do find it very odd that users who edited that page shortly after the edit by Mathilda37 actually let those edits stay or somehow didn't see them." As you were one of those who committed the sin of not noticing a bad edit, I'm letting you know although you aren't named in the case. Dougweller (talk) 06:51, 7 January 2014 (UTC)

You should have checked the small print in your Wikicontract. Right under the generous remuneration it states that you personally are responsible for checking and correcting all edits for all articles you have read in the preceding 5 months. The only exception are cabal-approved edits, of which you should get a monthly list (or activate the hidden button "mark cabal-edits" in the Freemason tab of your preferences). --Stephan Schulz (talk) 21:57, 7 January 2014 (UTC)

Wikimania 2014[edit]

Hallo Stephan Schulz, Du warst letztes Jahr schon auf der Wikimania, und hattest hoffentlich positive Eindr�cke. Deshalb ein kurzer Hinweis: die Wikimania 2014 steht schon jetzt vor der T�r. Vielleicht hast Du ja wieder Lust hinzugehen, oder Dir f�llt jemand ein, der gerne hingehen w�rde; oder hier liest zuf�llig jemand mit, der schon immer zur Wikimania wollte. Auch dieses Jahr vergeben die deutschsprachigen Wikimedia-Vereine Stipendien zur Teilnahme. Anmeldeschluss ist der 17. Februar hier ist das Anmeldeformular und mehr Details gibt es auf de:Wikipedia:Wikimania 2014. -- Dirk Franke (WMDE) (talk) 12:30, 4 February 2014 (UTC)

Hallo Dirk! Danke f�r den Hinweis - im Prinzip w�rde ich gerne kommen, aber ich habe immer um die Zeit private Termine, die ich auch gerne wahrnehme. Also vermutlich dieses Jahr nicht. London ist nat�rlich schon ein Kracher... --Stephan Schulz (talk) 13:18, 4 February 2014 (UTC)

The African-American inventors page[edit]

Why are you letting people falsely claim inventions?

Garret Morgan had nothing to do with the invention of the gas mask or the traffic light, those inventions are extensively covered on this website along with their inventors.

So why are you letting dishonest, politically motivated people distort and manipulate history on the page in question?

What needs to "cool down" is Wikipedia admins letting obviously bias people distort objective history.

This isn't a matter of opinion, my opinion vs yours, it's a matter of truth vs fiction.

--Savakk (talk) 21:22, 19 February 2014 (UTC)

It's because of my pathetic low self esteem, and meant to "compensate for the lack of black inventions when compared to every other race" (sic). Or so I've been told. Or maybe it's because the claim has been well-sourced, while your denial of it seems to be based on your personal original research based on your reading of an unreliable source. Somewhat surprisingly, our article on gas mask also lists Morgan as the inventor of one early version of the gas mask, and seems to have done so for several years without any objections. --Stephan Schulz (talk) 21:48, 19 February 2014 (UTC)

Recent global warming controversy[edit]

Hi Stephan,

I made the changes, but just wanted to follow up on the note you left beside the deletion: "(Blog references, not reliably sourced, nor even notable.)" It's true that I did not correctly source it on Wiki (I kept trying, but I don't edit Wiki very often.. I have done some to Michael Huemer's page). It is not true, however, that they are not notable. Econlog was ranked 12th in most influential economics blog in July 2013. David Henderson (the author), also has a Wiki page. He is a Hoover Institution fellow at Stanford University. His co-blogger is Bryan Caplan who works closely with Tyler Cowen, who runs the Marginal Revolution blog. Secondly, David Friedman also has a Wiki page. He is the son of Milton Friedman, the Nobel prize winning economist, and he is also an Economics professor at Santa Clara University. Finally, the third link that I tried to link was directly to the datafile itself so if there were any doubts on its validity, the reader could go straight to the source. The link is here. I may not have cited it correctly, but I think that it would warrant staying up. I would be more skeptical if there was no link to the data file itself, but I think that alone shows it is valid. Thanks. � Preceding unsigned comment added by (talk) 23:07, 1 March 2014 (UTC)


You are invited to join the discussion at Wikipedia:Articles_for_deletion/Jews_and_Communism_(2nd_nomination). Thanks. MarkBernstein (talk) 21:29, 9 May 2014 (UTC)

Thanks. I'm not, as a rule, a deletionist, but I'll give this one a good hard think. I have a hard time believing that Wikipedia is able to write a decent article on this topic, because the people who could don't care (enough), and the people who care enough are not able to do a decent job, or even understand "what the problem is". --Stephan Schulz (talk) 21:48, 9 May 2014 (UTC)

Race and Intelligence[edit]

I completely agree that there is a competence issue on the part of the original poster. If he or she had a clue and really thought that there was POV-pushing, he or she would have gone to Arbitration Enforcement rather than to a noticeboard. I haven't read the history. Were the original posters trying to claim that blacks were inherently inferior, based on the same biased sources as originally resulted in the edit wars that took the subject to arbitration? Robert McClenon (talk) 16:29, 19 May 2014 (UTC)

I've left a longish comment on the issue here. As far as I can tell, the user is more interested in claiming that there is no systemic bias against blacks in the US than in directly pushing a different agenda. But I didn't have the time to dig deep. --Stephan Schulz (talk) 16:51, 19 May 2014 (UTC)

Creation Evidence Museum[edit]

I presume you've seen the removal of material sourced to, which I reverted on the basis of [[4]]. Dougweller (talk) 14:21, 20 May 2014 (UTC)

I hadn't seen it, but I agree. --Stephan Schulz (talk) 15:35, 20 May 2014 (UTC)

Request for comment[edit]

Hello there, a proposal regarding pre-adminship review has been raised at Village pump by Anna Frodesiak. Your comments here is very much appreciated. Many thanks. Jim Carter through MediaWiki message delivery (talk) 06:47, 28 May 2014 (UTC)


Banned users are not allowed to edit. �Baseball Bugs What's up, Doc? carrots� 20:14, 8 June 2014 (UTC)

But you were reverting a lot more than just the banned used. And (but that's an aside), WP:DENY seems to be the wrong page to reference if that is your argument. Also note that edits by banned user can indeed be adopted by users in good standing, and then are allowed to stand (I agree that that can sometimes be problematic, but the opposite would be even worse - if a banned user adds a critical fact, we could never accept that). --Stephan Schulz (talk) 21:06, 8 June 2014 (UTC)
We have had this discussion many times. If you won't enforce the rule against banned editors editing, and if you continue to edit-war over it, you're just feeding the troll, who I'm sure is enjoying every moment of this. He's playing both sides of the game now, and even tricked StuRat into reverting the troll version back into place. �Baseball Bugs What's up, Doc? carrots� 21:38, 8 June 2014 (UTC)

the common name[edit]

Hi Stephan, If you can locate that thread I would be interested in seeing it. From my own research, I don't believe there is persuasive evidence to think either "climate change" or "global warming" are the common term. You may correctly remember the consensus, but of course, that can change. Can you find the thread? NewsAndEventsGuy (talk) 18:24, 15 June 2014 (UTC)

Sorry. If I remember correctly, that was before User: Short Brigade Harvester Boris took on that user name - and that was somewhere in 2008, IIRC. I don't have the time to sift through 5 years of archives. --Stephan Schulz (talk) 21:26, 15 June 2014 (UTC)
That's ok, I suspected it was ancient (outdated?) history. FYI, your comment at Talk:global warming that I vaguely referenced above was deleted, presumably accidentally, by another ed. NewsAndEventsGuy (talk) 21:30, 15 June 2014 (UTC)
Yes. I think it fell victim to an edit conflict - the Wiki engine is not always 100% reliable, I fear. But I've already restored it. --Stephan Schulz (talk) 21:46, 15 June 2014 (UTC)

GW sidebar[edit]

Hi Stephan,

I've been hard at work in my sandbox trying organize the chronological evolution of the scope of the GW article. It's been very time intensive, and some might think it's a wasted effort and that's ok. You're welcome to stop by, but that's not why I'm writing right now. I'll eventually post something at article talk when I'm done.

The reason I'm writing now, is to ask your assessment of an existing consensus (or lack of).

As a prelude, it is quite clear from my chronicle that there is a consensus to focus the article on the current episode of GW (whatever its called). People have sometimes come along wanting to say that any warming trend at any geologic time is "global warming", but there's a clear consensus to focus the article on the current one. I agree with that consensus, though I would like to explain the more limited meaning and then tell the reader the article is about the current one.

That gets me to shaky ground. Do you think there is a STRONG and INFORMED consensus that this article uses "global warming" pars pro toto for current climate change, or are there some eds who think this article is about that part of current climate change explicitly related to rising surface temperatures? As I read the comments, they seem to conflict with each other, and some comments even seem to be internally contradictory. What do you think? Have the GW editors really thought this question through fully?

Thanks for your thoughts as I prep my article talk page comments on point. NewsAndEventsGuy (talk) 11:10, 23 June 2014 (UTC)

Hi NAEG. Hmm. I think that there is a fairly strong and informed consensus among strongly informed editors. There are some editors who seem to be not clear on the idea, or don't like it, but. in my opinion, they lack some understanding of the topic in general, not just of this aspect. --Stephan Schulz (talk) 22:42, 23 June 2014 (UTC)
Either I'm laughing at my own ineptitude in asking, or I'm laughing at the irony. Let's try again. Obviously there is a strong consensus to just talk about the current episode of (whatever).
Question Is the rest of the consensus
(A) For GW to be the top (main) article about the entire subject of the current climate change?
(B) For GW to be about that part of the current climate change related to rising surface temps and exclude the rest?
(C) Something else?
It's hard to come up with knock 'em dead examples of what would be excluded under "B" (I haven't thought of any unambiguous ones) but it is pretty easy to imagine ongoing disputes whether this-or-that aspect is related to surface temp rise, e.g., thermohaline circ, SLR due to thermal expansion, species redistribution due to changing precip patterns....
I've been long interested in paring the article to make more effective use of sub articles and reduce redundancy with/among sub articles. Redoing the lead is part of that too. But before everyone gets hot under the collar to edit, I'd like to know whether we're operating under "A" or "B". (If it's "B" then we have the tweak the headnote.) What's your assessment of the current consensus on that point? Do we have one? Or do people just think we have a consensus but really have different ideas? NewsAndEventsGuy (talk) 23:11, 23 June 2014 (UTC)
I think A makes the most sense, and I think this view is shared by most others. However, online you will always find people clinging to etymological fallacies (present writer included ;-), and you will find everything-but-sceptics who will use any possible pretext to stop constructive dialogue. So if we have consensus depends a bit on the definition of the term. But I also think the way to decide this is via discussion, not meta-discussion ;-). If you challenge this, we can [[G�del, Escher, Bach|go up]] one more meta-level, but that means we have to eat more popcorn later.... --Stephan Schulz (talk) 22:45, 29 June 2014 (UTC)
Well, we agree on what the article should cover. Whether anyone's guilty of an etymological fallacy rather depends on what the RSs say, and fact remains there are 3 different definitions in the RSs
A. Rising global surf temps at any time for any reason
B. The current and human caused rising global surf temps (eg AR4 WG3 glossary)
C. Frequent common speech interchangeability with current climate change
Seems to me the only way to claim existence of an etymological fallacy is to argue that two of those are 100% wrong, and the other is 100% right. Any other argument relies on editorial judgment, which is by definition something subjective.
There is a simple way out, and that is to acknowledge all three, and nonetheless agree that the topic for this article is (as the hatnote says) the current climate change. We get there by incorporating the sources that say common speech often uses the two terms interchangeably. Otherwise we need to re-insert one of the definitions about rising surf temps and then continue to field objections such as DHeyward is making.
Back in time there was a commotions about "global warming" being THE common name. That was wrong then and its wrong now. "Global warming" is merely ((((A)))) common name. Is your common name bigger than my common name? That would be an absurd way to frame the issue. And besides, THAT is where the false dichotomy Nigelj was talking about arises. We shouldn't be favoring "a" common name, we should be acknowledging "both" common names. The former is editor desire; the latter is true to sources. Or am I totally barking mad?

RSN thread on Breitbart[edit]

Stephan, I'm trying to get that RSN thread closed. It is the 3rd forum we have on the subject at present. (Talk America (2014) & NPOVN as the other two.) Do you mind if I close it as unnecessary? Thanks. � S. Rich (talk) 16:26, 23 July 2014 (UTC)

Not really. I think there are different questions involved, and I certainly don't want to leave the impression that Breibart is reliable, but I don't see the need to discuss that now and in this context. --Stephan Schulz (talk) 17:12, 23 July 2014 (UTC)

Re the prot - he now seems to be indeffed. Aside: calling oneself John Galt is never a good sign William M. Connolley (talk) 13:06, 27 August 2014 (UTC)

I tried to give him some more rope, but PhilKnight decided he had had enough already - which I can fully understand. I'll unprotect. Yes, naming oneself Galt seems to suggest an objectively falsifiable world view and an extraordinary hubris even inside that world view. --Stephan Schulz (talk) 13:57, 27 August 2014 (UTC)
Eh? John Galt's novels show a dry sense of snark that even a stoat might appreciate, amusingly satirical if replete with Scotticisms. But perhaps the prof meant some poorly written fictional character, completely lacking in smeddum. . dave souza, talk 21:46, 27 August 2014 (UTC)

No, its better than that. There are some genuinely interesting bits. You'll want to blip over the (increasingly large) inserts of objectivism, but the overall story is quite OK. If you really strongly disagree with her politics then you might not be able to stomach it, but... well, as I said in my blog posting William M. Connolley (talk) 15:51, 28 August 2014 (UTC)

well said. CIR applies? NewsAndEventsGuy (talk) 13:26, 16 October 2014 (UTC)

Arguably. It's a combination of unclear language, motivated reasoning, and the use of very "advanced" idea that I suspect are not fully grasped (not that I grasp the hole post-modernist myself, but at least I know some of my limitations). --Stephan Schulz (talk) 12:11, 17 October 2014 (UTC)

Albert Einstein Edit[edit]

Hi, I noticed you removed my edit to Einstein's page which remarked that his cause of death was suspected to be syphilis by his personal doctor. I understand it's considered a fringe theory by modern academia; however, with all due respect, I believe it is of no import. It's not a fringe theory that his doctor attributed his death to syphilis (technically, "a lues" in the language of the day), and I hope we can agree that the opinion of Einstein's personal doctor regarding Einstein's cause of death deserves a spot on his Wikipedia page.

Looking forward to your response!

I reversed your edit, maybe that was rude and I should have waited. Sorry, I'm new to this!

GarretKadeDupre (talk) 04:06, 16 November 2014 (UTC)

Hi GarretKadeDupre! I have no problem mentioning the incident. But mentioning it without context and balance suggest to the casual reader that the claim is true, or at least taken seriously (why else would we include the opinion of a largely unknown person?). And it's quite debatable if Plesch was indeed Einsteins "personal physician". He had treated Einstein in the 1920, but, as far as I can make out, not after his emigration to London and Einstein's emigration to the US - i.e. he had not been his physician for more than 20 years when Einstein died. In other words, the factoid itself may be correct, but the phrasing gives a very wrong impression on two key points. No, you should not have restored the edit - the suggestion is WP:BRD - discuss after the first revert. And a better place for the discussion might be talk: Albert Einstein, to get input from more users. But these are both neither universal laws nor major problems. --Stephan Schulz (talk) 07:35, 16 November 2014 (UTC)
Thanks for the advice! By the way, you're right, I did not realize the 'diagnosis' was made only after Plesch had not been Einstein's doctor for two decades.

GarretKadeDupre (talk) 20:51, 16 November 2014 (UTC)

Ok if....[edit]

Hi Stephan,

In the interest of preventing future disruption I may decide to seek some form of sanction on another ed with whom we have both recently interacted. I am writing to ask if it is OK to refer to remarks you and the other ed exchanged, or any comments you have made about the other ed. Questions? Ask 'em! Advice or criticism? Fire away! Thanks for your time. NewsAndEventsGuy (talk) 20:21, 18 December 2014 (UTC)

Hi NAEG! Thanks for asking. I try to avoid writing things I don't want to be read. Please don't quote me out of context, but feel free to otherwise use what I've stated. BTW, is there a better colloquial nickname for your user name? "Guy" is to ambiguous... --Stephan Schulz (talk) 21:53, 18 December 2014 (UTC)
OK, thanks. Re name, NAEG is most used by others (said "nag"). Guy and News also work. Whatever. Thanks for asking. NewsAndEventsGuy (talk) 22:30, 18 December 2014 (UTC)
Back then the Spanish inquisition was quicker. ;) Serten II (talk) 10:35, 19 December 2014 (UTC)

──────────────────────────────────────────────────────────────────────────────────────────────────── UPDATE - It's a bit of conundrum having both reservations about Serten's new article "IPCC consensus" as well as his behavior. If one takes action, is it "better" to seek AFD about the article first, or AE about the editor first, or do both at the same time? And if one is better than the other, why is it better? It's hard to argue with erring on the side of hope, or treating the situation as I'd want to be treated in his place. The answer I came up with in both respects was to AFD the article first (assuming I think it still merits AFD after more days of work), thus giving Serten an opportunity to rebut criticism within the bounds of our core principles, the WP:TPG, and WP:ARBCC. For an AFD, if still needed, it would be nice to get meaningful participation from editors with knowledge in the relevant areas. I'm not sure if that is easier during the holidays, or waiting until people return to wiki after the seasonal festive chaos. And as I said, maybe it will mature enough to avoid AFD in the meantime. Thoughts? NewsAndEventsGuy (talk) 14:12, 19 December 2014 (UTC)

My problem with the article is that Serten has a certain POV, and that his language skill is so bad that everything essentially needs to be rewritten from scratch. There may be some valid ideas in there, but at the moment it looks like half of a POV-fork and half of a discussion of a non-notable idea about "consensus" as a term, not the consensus itself. I'd go with AfD first - per WP:AGF I tend to think that his behaviour is mostly a problem of his limited skills in English - he expresses himself badly, and while he mostly does get the gist of the discussion, he does not get the nuances. It doesn't help that he jumps from topic to topic to topic as soon as discussion may lead to progress. --Stephan Schulz (talk) 14:41, 19 December 2014 (UTC)
Wow - I rarely feel entirely understood to the last nuance in these pages, but I could have written that myself. Awesome. NewsAndEventsGuy (talk) 14:44, 19 December 2014 (UTC)
To spam you a bit, JzG has done the sensible thing. I'm beginning to appreciate that IPCC SPM'a need "the firm agreement of essentially all the world's leading climate scientists plus the consensus of all participating governments without exception",[5] so it's a consensus of governments as much as of scientists. Have to seek out more sources. "IPCC consensus" is also something of a contrarian theme, so care is needed with weight and source checking. . . dave souza, talk 15:58, 19 December 2014 (UTC)

2015-02 unreliable source[edit]


Since you made this deletion, you may be interested in this edit, and what will likely follow. [[User:Visite fortuitement prolong�e|Visite fortuitement prolong�e]] ([[User talk:Visite fortuitement prolong�e|talk]]) 22:23, 2 February 2015 (UTC)

Unfortunately, I'm really quite busy at the moment. But I gave a comment at the talk page. --Stephan Schulz (talk) 22:18, 3 February 2015 (UTC)
Your edit summary, if I understood it correctly, said the deleted material copied Gatestone ("copied from the unreliable Gatestone report"), but in fact they were published earlier. So I reverted. � Brianhe (talk) 16:11, 4 February 2015 (UTC)
I'm not sure I understand you. The Wikipedia text was (in all likelihood) copied from Kern's article at Gatestone here, which was published on January 20th. The first time that material came into our article was here, on February 1st, partially just copying stuff from Kern, and also adding him as a reference directly. So User: Korny O'Near definitely knew of the Gatestone article when (s)he added these sources, and I find it very implausible to assume that (s)he assembled, by accident, the same sources in nearly the same words by independent research. Indeed, (s)he at least seem to suggest that (s)he only looked at the original sources through Google Translate (or similar), if at all. What we have is Kern, an unreliable and biased source, assembling a set of unrelated articles into his narrative - clear OR. Of course Kern is allowed to do the OR for his "think tank" political rationalisation. But there is general consensus that Kern is unreliable (or at least nobody so far has argued otherwise). So the whole reason to consider these largely unrelated tales of different urban problem zones part of one narrative breaks away. Letting it standing is substituting Kern's OR with our own. I'll copy most of this over to the talk page, so if possible, please keep the discussion in one place over there. --Stephan Schulz (talk) 22:02, 4 February 2015 (UTC)

List of participants in the creation�evolution controversy[edit]

Why would "Opponents of Creationism" be less accurate than "Scientific Community"? Every person and organization listed under "Creationist" is or was a member of the scientific community. --Kaptinavenger (talk) 08:41, 6 February 2015 (UTC)

Because a) they are not defined by their opposition and b) no. --Stephan Schulz (talk) 08:43, 6 February 2015 (UTC)

On this list the only distinguishing characteristic between one group of scientists and another is their position on creation. Listed under the "Creationists" are geophysicists, paleontologist, biologists, zoologists, physicists, cosmologists, engineers, mathematicians, etc. Shouldn't these Scientists be classified as in the Scientific Community? --Kaptinavenger (talk) 09:01, 6 February 2015 (UTC)

Very much no. A few of the creationists do have legitimate scientific credentials. Even less have them in the relevant field. They don't reflect the view of the scientific community, but stand in stark contrast to it. --Stephan Schulz (talk) 09:10, 6 February 2015 (UTC)

Every Person Listed under the creationists have a MS, BS or Ph D. They are all well accredited scientists in their fields and their work in this field is widely accepted. They don't reflect the view held by some members of the scientific community of which they are also members. --Kaptinavenger (talk) 09:28, 6 February 2015 (UTC)

Can you tell me what relevant degrees e.g. Kent Hovind or Ken Ham have? Or how George McCready Price and Frank Lewis Marsh are members of anything this side of the world? --Stephan Schulz (talk) 09:44, 6 February 2015 (UTC)

Perhaps we should remove any persons on the list that would not qualify as a scientist. Is, or should be, every person on the side of Evolution considered a scientists? Surly there are some Evolutionists who do not apply scientific method to their belief in evolution. And Dr. Marsh got his Ph. D. in Botany From NU, Mr. Price perhaps not an S degree but he does have his Masters. Does a person need to have a degree to be a participating member of the scientific community? The Scientific Community includes anyone who uses scientific methodology. Not all scientists agree on every topic, though they are still scientists.--Kaptinavenger (talk) 10:03, 6 February 2015 (UTC)

I don't think "Evolutionists" is a word outside the Creationist camp. You miss my point with respect to Price and March. Price has been dead for over 50 years. March has been dead for over 20 (and has not published for nearly 40 years). They are historically interesting. They may or may not have been members of the scientific community in their time, but they are certainly not members now. All that said: We should probably move this discussion over to [[Talk:List of participants in the creation�evolution controversy]] - whatever we here do to agree or disagree has little staying power unless all interested parties have a chance to participate. --Stephan Schulz (talk) 22:06, 6 February 2015 (UTC)

Well what ever is ultimately decided, 200+ Edits from ~50 Editors, 9 Years of work(though I am just getting into it), has been nominated for deletion. See � Preceding unsigned comment added by Kaptinavenger (talk " contribs) 07:16, 9 February 2015 (UTC)


Dr.S, I am still curious to what percentage of the new professors at the recent reception in [[Baden W�rttemberg]] agree or side with Project Steve.
Also, the overwhelming consensus amongst "academia" is not new. Did you know, Martin Luther faced this type of opposition when making propositions that disrupted the status quo. And Jesus was crucified for it. The Young Earth Creation Scientist a.k.a. Fundamental Christian Scientists, see the overwhelming consensus as confirmation. If academia did not see Biblical based science as a viable threat to their existence i.e. if they thought there was no evidence to be found in the science produced from a Biblical World View, they (the Steve's) wouldn't care. The great deal of concern shows the doubt. The doubts should be tested, not silenced. Kalam --Kaptinavenger (talk) 03:41, 11 February 2015 (UTC)

You might want to look at Galileo Gambit. "They" also laughed at Bozo the clown. Creationist claims have been tested over and over and over again. As long as you stick with science, they have been falsified over and over and over again. You can, of course, move outside the realm of science and postulate an omnipotent creator who created the universe "as if" it were ~14 billion years old, complete with red-shifted star light in transit, buried dinosaur bones and a meticulous care about arranging different isotope ratios between different rock types. That has its own problems, both philosophically (omnipotency has build-in contradictions) and theologically (why would a god do that?). It also does not get you to anywhere close to the biblical story. But in particular, it is no longer science and should not claim to be science. Luther wasn't making scientific claims, but religious and political ones. We really know too little about the historical Jesus, but I doubt that he was preaching about the rate of sediment consolidation, or measurements of the hyperfine structure. Indeed, the standard Christian assumption is that Jesus was sacrificed by his older self to redeem the rest of humanity. As for new professors in Baden W�rttemberg: It's not even a topic. It's not part of the public discourse. Nobody of any standing claims that Biblical creationism has scientific merit - not even the pope. --Stephan Schulz (talk) 09:52, 11 February 2015 (UTC)
While on a walk in Damascus today, I thought about an epistle I would write to a man on youtube. I thought of writing you one also, but decided to offer you a barnstar and share my epistle to James, with you. Keep in mind this is the end of a long conversation. "Yes James, now, practicing reason and logic are base principles or in the foundation of what I consider "My" religion, although my ability to follow logic and reason does have its limits. I am no great thinker, although I do think. I do rather like most Church Services. The Sing Songs, The Study, the Prayer. I like these things. I will admit its been a over a year since I've been to a Sunday Service. In my defense I gather with believers Regularly, like almost every Thursday (that's really good for me). That being said, the Topic of the Flick is "Why I Think Jesus Didn't Exist". And I will end my discussion on this page with: "Why I think Dr. Richard Carrier and Santa Clause Prove Jesus Created the Universe." No one in His story can make the claim that Everything, Dr.RC, Big Red, Easter Bunny, Dolly Lama, Hitler, Muhammad, Rocks, Sand, Water, I mean everything, our conversation right now, and cups, and the Big Bang, can, does, and is used to Point Towards them. Except Jesus. So I try to Love. Like Jesus Said." You can find the full conversation here.

NSIDC image[edit]

Hi Stephan, the image here, i thought to update it since it is on the Arctic sea ice decline page, with the April record. However, the file name is stating September, and not sure. What do you think, have two images or update more frequently? Thanks. prokaryotes (talk) 03:31, 16 May 2015 (UTC)

Hmmm. Sea ice is on a yearly cycle. As far as I know, in the Arctic the yearly minimum is around September. The yearly maximum is around April, but is not usually considered as significant, as essentially the Arctic ocean is limited in size and always freezes over completely in winter, so the maximum extend varies relatively little. It's the opposite in the Antarctic, where the pole is on land - there, the minimum sea ice in summer is not very significant, as basically all sea ice except for the large shelves vanishes. On the other hand, in winter Antarctic ice can grow without obvious geographic limits. So in my opinion we should have September images for both Arctic and Antarctic (minimum for Arctic, Maximum for Antarctica), and update them yearly. --Stephan Schulz (talk) 12:22, 16 May 2015 (UTC)
The article here is only about the Arctic and There are two months each year that are of particular interest: September, at the end of summer, when the sea ice reaches its annual minimum extent, and March, at the end of winter, when the ice is at its maximum extent.1 However, the April month set a new record, with second lowest in the sat record, 2007 was less. After some thought i think we should show Max and Min month on the page dedicated to the state of the ice record. I could make those changes later tonight. prokaryotes (talk) 15:21, 16 May 2015 (UTC)
On February 25, 2015, Arctic sea ice extent appeared to have reached its annual maximum extent, marking the beginning of the sea ice melt season. This year�s maximum extent not only occurred early; it is also the lowest in the satellite record. 2 prokaryotes (talk) 15:44, 16 May 2015 (UTC)

There are different levels of wrong. Several of the original attempts were just plain wrong (probably because someone with little German and few scruples put it over the blogosphere).

Bible copyright[edit]

Yeah, I was amazed when I wasn't able to get Jehovah's Witnesses to understand why they should release their Bible translation into the public domain and use trademarks to protect it instead (which the Fortune 500 company Red Hat does). Especially in light of projects like Unspell that had to use KJV.Scientus (talk) 07:27, 30 June 2015 (UTC)

I agree in spirit, but Red Hat Linux is not public domain - it's Free Software or, depending on your philosophical outlook, Open Source Software under a variety of licenses, but most significantly the share-and-share-alike Gnu General Public License. This is similar to Wikipedias Creative Commons licensing. I kinda like the KJV from a language point of view, but it is full of anachronisms old and new. It's weird that one can copyright the Inspired Word of God to begin with - I suspect all the bible sellers will have to confront "Thou shalt not take the name of the Lord thy God in vain" when someone is mightily pissed of with the spin given to Her word. --Stephan Schulz (talk) 14:14, 30 June 2015 (UTC)

Hi Stephan! Answering here because the Misc Desk and Ref Desk Talk are currently semi-protected, so as an IP Editor I can't contribute there.

Robert Spencer Edit[edit]

Hi Stephan, I added the Robert Spencer defense to be a leader of a hate group accused by SPLC because of the principle of impartiality of the page. He was accused by the SPLC as a hate group and I thought it should have his response. I've already seen this in the page of "David Horowitz" where it is written his response to Morris Dees of SPLC. Anyway, if the edit stills does not fit to the principles of wikipedia, I obey. Thank you — Preceding unsigned comment added by Odirjmm (talkcontribs) 15:08, 6 November 2015 (UTC)

The main problem is that Spencer is not a reliable source, but rather a fringe publicist. It's not particularly notable that he tries to discredit organisations that disagree with him. Take a look at WP:WEIGHT - we're not looking for "equal treatment", but for coverage that reflects reporting in reliable sources. If you can find third-party reliable sources that make points in favour of Spencer, then we can add those. But that Spencer thinks Spencer is right and others are wrong is not useful. --Stephan Schulz (talk) 16:58, 6 November 2015 (UTC)

Funny you should post this. I'd posted earlier to the noticeboard on the same topic, but did not have a chance to update the Talk page. I've done so now: Jochen Peiper Talk page | Agte. Cleaning up dubious unsourced or poorly-sourced information has been an on-going 'project' where a couple of editors are also involved; if you are interested, you can review Waffen SS and Individual articles and the thread right below it. Or check out my 'collection' :-) K.e.coffman (talk) 01:54, 18 December 2015 (UTC)

Thanks! Unfortunately, Wikipedia competes with several other projects, so I have to limit my time and pick my battles carefully. But I very much appreciate the sentiment! --Stephan Schulz (talk) 12:39, 18 December 2015 (UTC)

Scientific consensus[edit]

Your revert at Scientific consensus has been noticed. Biscuittin (talk) 00:16, 22 December 2015 (UTC)

Very good. I hope my explanation at global cooling has also been noticed. --Stephan Schulz (talk) 00:24, 22 December 2015 (UTC)
So do the red bars not mean that it's getting warmer? Biscuittin (talk) 00:52, 22 December 2015 (UTC)
No, not in themselves. Each bar only shows a single month anomaly, i.e. a red bar shows that that month was above the 30 year average. The changing distribution from blue to red bars (and the changing lengths of the bars) represent the temperature increase. What you see is semi-random variation on top of a secular increase of the base temperature. Check out File:Satellite Temperatures.png, which shows the UAH and other reconstructions in parallel, and also includes the linear regression trends for the different temperature series. --Stephan Schulz (talk) 01:09, 22 December 2015 (UTC)
(talk page stalker) Besides temp readings, one also looks at what's happening around the world. Try googling images on [multiple lines of evidence of global warming] and poke around in the nice pictures. For example, the study of Phenology shows that spring is coming earlier in many places. Or my personal unexpected favorite, the bonanza-yet-crisis in alpine archaeology pretty much everywhere. NewsAndEventsGuy (talk) 01:49, 22 December 2015 (UTC)

Hi Setphan, I am afraid that if you won't take the action now, it won't happen in the coming months at all: Should you redirect "Data Serialization Languages" to "Serialization? If in computing, these terms are enough synonymous, it can be nice.

Ben-Yeudith (talk) 01:42, 11 January 2016 (UTC)

Done, albeit for the singular data serialization language. But every user can create redirects - it's not a special right for admins. See Wikipedia:Redirect. --Stephan Schulz (talk) 07:50, 11 January 2016 (UTC)


Wheat, yes, wheat. If you pick a species that has trouble with heat, you will see that. But is that a good way to evaluate the overall situation? I've come to your talk page to ask a question -- is the goal of this type of discussion to reach truth, or to make debating points? (actually there is a third possibility -- you may be genuinely unaware that it's not a representative example). I've come to your page because I believe such a question is better asked in a less-public forum. I realize your page is still public, which is unfortunate; I would ask it in a fully private way if I could do so. Feel more than free to take your time in answering, or for that matter, to delete this on sight. Best wishes. Really. CometEncke (talk) 15:04, 21 January 2016 (UTC)

Hi CometEncke! Let me first point out that I linked to two studies (the first two that sprang to my eye as applicable), and that only the first concentrates on wheat, while the second looked at about a dozen different crops. What I try to say is that this is a complex, multivariate problem and that the simple answer is likely to be wrong. I'm usually always interested in getting to the bottom of the subject matter (some say to a fault), but I've come to realise that I cannot do that with all of reality (despite the hubris expressed by the Bacon quote on my front page). So unless it's really within my field or I'm extraordinarily interested, I apply some heuristics. One such heuristic is that if someone says that something is "obvious" or even "blindingly obvious", I take a short track to Google Scholar and check some related papers. If that shows me that the problem is indeed complex and multifactorial, I assume this is a case for H.L. Mencken ("...neat, plausible, and wrong"). In this case I think that the nuanced, conservative discussion by the IPCC is more justified than "it works in my greenhouse for cucumbers, therefore CO2 will save us from world hunger" (sorry for the hyperbolic summary - I trust you get my point). If you want to convince me otherwise, you would either need to make an incredibly clear and short and convincing argument, or get your opinion published in a serious peer-reviewed venue, so that I know that you convinced real experts of the validity of your argument.
If you have a real need for private conversation, my email is enabled. But I normally prefer to keep Wikipedia discussions in the open - after all, making knowledge accessible is the whole point of the project. --Stephan Schulz (talk) 16:19, 21 January 2016 (UTC)
Well, OK, but as any farmer from a hot region will tell you, wheat is not for the hottest weather. Rice and millet do much better; maize can also be an option, though extra CO2 doesn't help it much. If your goal is to come up with crops that do poorly in hot weather, even with extra CO2, you can find them. But from the standpoint of food production, surely the more relevant question is not whether there exist crops that do poorly under those conditions, but rather, whether there exist crops that do well under those conditions. And the answer to that is a resounding "yes", as a little googling will tell you, or even just checking the population figures for South Asia. If you follow the evidence wherever it leads, regardless of where you may want it to lead, you will find that multiple, independent strands of evidence all point to the same conclusion, including the CO2 data themselves (the trend of the May-October drop, that is). And yes, it will be blindingly obvious, screaming at you like the evidence in a murder case where the jury got it wrong. CometEncke (talk) 17:55, 21 January 2016 (UTC)
CometEncke, congratulations on your blindingly obvious thoughts – however, for this reasoning to appear in Wikipedia, it must first be published in a reliable third-party source. A scientific journal is the best place to get credence. . . dave souza, talk 18:11, 21 January 2016 (UTC)
I have the feeling that you only read about half of what I wrote. Anyways, even stipulating that you are right that there are some crops that will do better, it's far from trivial that it's possible to replace existing agricultural systems - you need not just suitable climate (and remember that that will keep changing for a while), you also need skills, seeds, suitable soil, tools, and markets, to name just a few. --Stephan Schulz (talk) 19:00, 21 January 2016 (UTC)

Where's the Bacon? My search-fu didn't find it, am hoping this was a reference to the title page of On the Origin of Species, but any Baconian epigram will be of interest. . . dave souza, talk 18:14, 21 January 2016 (UTC)

I have taken all knowledge to be my province, which according to q: FrancisBacon is from a letter to William Cecil, 1st Baron Burghley. My pretentious user box is at User:Stephan_Schulz/knowledge. --Stephan Schulz (talk) 18:53, 21 January 2016 (UTC)
Thanks! Very modestly placed in the userbox, didn't know about that one. . dave souza, talk 19:15, 21 January 2016 (UTC)
"I have the feeling that you only read only half of what I wrote." In one case, you are right. After I looked at your "wheat" paper, I felt it was sufficiently irrelevant that I didn't go to the second one. Interestingly, this whole discussion got started because I felt pretty much the same thing and said so on the article talk page, not only in relation to you. So perhaps in that sense we are alike. I agree with you that our discussion has gone beyond the level of what can be included in Wikipedia, which is an additional reason to take it here, as opposed to the article page. As to your question of whether the agricultural system can keep up, I would refer you to a graph of worldwide grain harvests. I am curious whether you still think your "wheat" argument is evidence against my assertions about where agriculture is likely to head in a high-carbon world? DS -- welcome to the party. The scientific journals do talk about this all the time -- here is two reviews of a whole lot of literature, [7][8], which, according to google, have been cited 400 and 600 times, respectively. A whole lot more out there. The evidence is truly overwhelming. As this user astutely notes, facts do not cease to exist because they are ignored. Fortunately such is the case for food production and will remain so no matter how many people mock me for saying "blindingly obvious". CometEncke (talk) 12:33, 22 January 2016 (UTC)
Now I have not only the feeling that you read only half of what I wrote, but that you also read things I never wrote, and don't really read things you suggest we should read ;-). I have not made "a wheat argument" - I have made a plausibility check on you claim that it is "blindingly obvious" what the effect of higher CO2 on agriculture is, and found that it is very much not obvious. Indeed, the first source (in New Phytologist) you offered above very much said so. The second (the Oecologica paper) has very little predictive relevance for real-life open-field agriculture, as it is not a literature review, but a description of one experiment in a glass house with otherwise controlled conditions. Even then the paper concludes that "these data show that plant responses to elevated atmospheric partial pressure of CO2 depend on complex of partially compensatory processes which are not readily predictable". So I'm at a loss to understand where your "blindingly obvious" is coming from. As for the graph: You do understand that grain harvest are not primarily influenced by CO2, but by new cultivars and by the increased use of energy- and nutrient-intensive farming techniques, many of which are unlikely to be sustainable in the long term. Indeed, I find it a bit ironic that that the first hit Google gives me for "graph of worldwide grain harvests" starts with ""Global Grain Stocks Drop Dangerously Low as 2012 Consumption Exceeded Production... The drop was largely because of droughts that devastated several major crops—namely corn in the United States (the world’s largest crop) and wheat in Russia, Kazakhstan, Ukraine, and Australia". --Stephan Schulz (talk) 13:11, 22 January 2016 (UTC)
"Require further study". Sure, there is a lot we still don't know, and this was even more the case in the past. There is plenty of debate about all sorts of details. I'm still curious if you still believe your wheat reference is significant. If so, why? If not, why not say so? You may have noticed in this discussion that I have had no hesitation agreeing with you on certain questions when I thought you were correct. I guess I'm challenging you to do the same, or, if you can't, to explain it. Such action would give me confidence that a search for truth is more important than plausibility attacks, and would further give me confidence that moving on to other issues has value. CometEncke (talk) 07:19, 23 January 2016 (UTC)
Sorry, but my perception is not that you agree on certain questions, but that you are moving the goal posts. Remember, this started out as a discussion over at talk:Marco Rubio about the question if a number of sources, one of which headlines (!) "Marco Rubio says human activity isn't causing climate change" are enough to support the claim that "Rubio disputes the scientific understanding of climate change, arguing that human activity does not play a major role in global warming". Then you made claim about the IPCC (which Boris has refuted over at User_talk:MastCell#Rubio_and_climate - let me refute it here again, more explicitly: "Evidence since AR4 confirms the stimulatory effects of carbon dioxide (CO2) in most cases and the damaging effects of elevated tropospheric ozone (O3) on crop yields (high confidence). Experimental and modelling evidence indicates that interactions between CO2 and O3, mean temperature and extremes, water, and nitrogen are nonlinear and difficult to predict (medium confidence)" (executive summary, page 488, emphasis mine))) and about the "blinding obviousness" of the influence of CO2 on agriculture. Now we are discussing if wheat, a major staple crop and the major source of plant protein is a good example for discussing the claim that the effect of increase atmospheric CO2 on agriculture is "blindingly obvious" - apparently because wheat is more sensitive to heat than some other crops. So let me state it here: Yes, I think this is a relevant example for the claim that the situation is not blindingly obvious, but complex. If you are looking for something that we probably agree on: I agree that an increase in CO2 from the base level to a moderately increased level alone increases primary plant productivity for most plants in situations where growths is not limited by the unavailability other resources. But that is something the IPCC acknowledges as well. It just doesn't stop there. --Stephan Schulz (talk) 10:09, 23 January 2016 (UTC)

──────────────────────────────────────────────────────────────────────────────────────────────────── Thank you for addressing my question. And sorry for responding slowly -- real life had me off wiki for a few days. Now for the question about the overall effect of CO2 rise on plant growth. I am glad we agree on the effect of CO2 in isolation. Now let's examine the combined effect. There are three things we need to consider: the direct effect of CO2, and the indirect effects of rising temperature and changing rainfall (I won't say rising or falling; more on that in a moment). Rising CO2, we agree, in isolation, stimulates plant growth. I think it's fair to say, in addition, that the effect is large. For a doubling of CO2, I would suggest that it would not be remotely credible to suggest that the stimulatory effect of CO2, in isolation, would average only 10%, across important crop species (however one defines that). I would suggest that even only 20% would be surprising, though it would be out of the range of "not remotely credible" at that point. Now, temperature. You and I both agree that a doubling of CO2 will produce a rise in global average temperature. The IPCC I believe estimates 3 degrees C. I think that's an overestimate but will accept it arguendo. Before making any prediction, simply an observation about current agriculture: the pattern is that the warmer the region, the greater the harvests tend to be, at least across most of the range of current temperatures on Earth. In terms of agricultural productivity, Nigeria > Mexico > France > Norway > Alaska > Greenland > Antarctica, for example. I am unaware of any evidence one way or the other about the hottest regions with reasonable amounts of water. It would be interesting to know that. I mean, obviously the Sahara has very little agriculture, but I think "dry" is the issue there more than "hot." So let's save that question for water. In light of this, I believe it is fair to say that the temperature increase, in isolation, is likely to produce an increase in agricultural productivity. It is possible that the hottest regions may suffer a loss; I am not sufficiently familiar with the evidence to answer that. But for the regions listed above, an increase seems certain for temperature zones from France on down and likely even at the Mexico level, ignoring water for the moment. Nigeria I don't know one way or the other. But overall, in light of this, it seems fair to expect that temperature would also produce an increase.

Now, changes in rainfall patterns. The IPCC talks from time to time about "more droughts." But have they made any effort to quantify whether or not we are currently seeing no droughts? I am unaware of any such effort. I find this curious; certainly the IPCC has shown that it can quantify a claim when it desires to. Furthermore, "more droughts" is a claim which could be quantified in terms of actual precipitation data. Make a mathematically reasonable definition of "drought" or "precipitation variability"; I don't care what it is. A yeare with less than 50% of the mean precipitation (drought); the standard deviation of precipitation divided by its mean level over a 20-year period ("precipitation variability"); whatever. Then, based on actual rainfall data, it would be possible, and I daresay not difficult, once one had gathered the data, to determine a trend. One could then determine what that trend is, and put it in the IPCC report.

Feel more than free to correct me on this, but as far as I am aware, the IPCC has not done any such thing. That suggests to me that the data do not show any unfavorable trend in droughts to date. Feel more than free to correct me on this if I am wrong. But if I am not wrong, then I will infer from that that so far, precipitation patterns have not become any worse than they were in the past. Because if they had, we sure as hell would have heard about it.

Therefore, overall, we have one change (CO2) which is uniformly favorable to harvests, and dramatically so. A second change (temp.) which is mostly favorable, or possibly entirely, depending on what happens at the hottest end of the scale. And a third one (rainfall) which I infer that data (as opposed to models) don't show overall worsening. Lastly, at high CO2, the plants need less water overall. So even some worsening in rainfall, if it were to happen, would be overwhelmed by that effect. Hence my "blindingly obvious". There is actually one more piece of evidence, weaker than the others IMO, it's possible there is another cause, though I'm not aware of one. That's the trend in the May-Oct. in the Hawaiian CO2 data. That drop has been increasing over time. Not uniformly, there are ups and downs, but the overall trend is clear. This drop is generally attributed to the Northern growing season. If the drop is increasing, the natural inference is that said growing season is getting stronger. It is possible there is another explanation, though I haven't heard it. CometEncke (talk) 18:04, 25 January 2016 (UTC)

How do you get from "an increase in CO2 from the base level to a moderately increased level alone increases primary plant productivity for most plants in situations where growths is not limited by the unavailability other resources" via "Rising CO2, we agree, in isolation, stimulates plant growth" (drops a lot of qualifiers) to "uniformly favorable to harvests, and dramatically so"? It's not just crop plants that profit - weeds do likewise. And "uniform" is the opposite of what the sources say - indeed, it's very much non-uniform. There is also very little data on plants grown in cultures (where they compete for resources). As for droughts: It's not just annual precipitation thats relevant, but precipitation at the right times of the year, not to mention the vanishing buffering capacity of vanishing glaciers. Winter snow that melts in spring is useless for irrigation in summer. As for the rest: I suggest you take a look at the IPCC reports instead of speculating about what they don't contain. WG2AR5C3 deals with hydrology, and WG1AR5C2 has information on the development of precipitation and the hydrological cycle. --Stephan Schulz (talk) 19:01, 25 January 2016 (UTC)
I did drop some qualifiers. It's a fair point. Sorry about that. The IPCC has lost my confidence with its repeated over-predictions. We are up to their 5th report now, and so far we are well below their temp. predictions for the first four, taking business-as-usual emissions, which is more or less what we've had. How many times can one cry wolf? Why go after *me* so hard; isn't this about finding truth? CometEncke (talk) 22:37, 25 January 2016 (UTC)
You might want to look at this page and the papers referred therein. Of course, the IPCC reports are current and evolving science, so their predictions are not perfect. But they are, contrary to cherry-picking contrarian claims, quite good. "This" thing we are doing is cutting through misinformation and misunderstanding. I'm a computer scientist - indeed, I'm an expert in a very small field of algorithm design, logic, search heuristics, with a smattering of knowledge about air traffic control and machine learning. I don't have the hubris to believe I can contribute significantly to finding "the truth", or even the increasingly better approximation to the truth that science gives us, in a field as wide and complex as climate science - at least not without overturning my career and starting again at an undergrad level. On the other hand, I have a decent layman's overview of the field, and I can sometimes recognise claims as plain wrong. If I see those, I try to correct them. I assume good faith, i.e. I assume that my debating partners will be happier to improve their understanding than to score debating points. On the other hand, if not, I have little sympathy. I can't stand e.g. creationists who serve the same over and over refuted claims over and over again. If you don't trust the IPCC, that's your prerogative. But making wrong claims about them and their reports is not. --Stephan Schulz (talk) 23:02, 25 January 2016 (UTC)
I'm sorry to see how this discussion has gone. My comments have been full of statements like "feel free to correct me on this, but . . .", or "I did do x. Sorry about that", or even "There might be another explanation, but I haven't seen one." (FWIW I did think of one possibility afterwards. No idea if it fits or not.) If the intent was to win me over, it's been done; it would have involved noticing more places where I was obviously correct, and making corrections gently, rather than focussing relentlessly on the negative, and above all, realizing that learning from the other guy is a two way street. So, in this case, you've lost me. You may feel that was a foregone conclusion. It wasn't, but it's a done deal now. Still, best wishes, and better luck next time. I'm a technical person too. I don't want to get specific, but you can be sure that if I believe something to be factually correct, I don't care in the slightest whether or not it fits with any opinion I have; I will revise my opinions, not facts. Random case in point, Adnan Syed from "Serial" is innocent. Not "not proven guilty." Proven not guilty, beyond a reasonable doubt. In time, the courts will agree, at least up to "not proven guilty." Bank on it. Kevin Urick should be in prison, but that will never happen. And best wishes, still. Really. CometEncke (talk) 00:42, 26 January 2016 (UTC)
Maybe we have different expectations. I'm not proselytising for a religion, trying to safe souls whatever the cost. Also see Richard Dawkins on a related topic of methodology. I had no idea who Adnan Syed is, nor why you brought him up, but I notice that you apparently have formed a very strong opinion on the issue - based on what? A polemic podcast? I'm not saying you are wrong, but I find no substantial support for you being right, either. --Stephan Schulz (talk) 15:13, 3 February 2016 (UTC)
I brought him up to make the point that I base opinions on facts and evidence, everything else be damned. My mind was actually pretty clear before the polemical (and dead right) cast came out. A friendly wager the courts agree and AS is out this year. CometEncke (talk) 22:07, 11 February 2016 (UTC)

Complexity of Addition in Finite Automata[edit]

I couldn't understand the finite automata shown in the Article on Finite Automata(P.65).It might be because I'm weak in binary mathematics.Addition is very simple.I can't get why the author has shown 'addition' as complex.Could you help me and give a brief explanation of each state given in the finite automata.JUSTIN JOHNS (talk) 06:49, 27 January 2016 (UTC)

@JUSTIN JOHNS: I'm rather busy at the moment, and the slides are missing the main part (the presenter). But as I understand it, the automaton is processing a sequence of 1-bit-additions (least significant bit first) and checks if the overall addition is correct (so it's not performing addition, but verifying addition). The alphabet of the automaton consists of the individual combinations of 3 bits (the first two are the input, the last is the lower order bit of the output), i.e. each of the characters of the alphabet is one of the 3-bit combinations (written as a vertical vector with a dash, but that is just syntactic sugar). As you probably know, a 1-bit addition has a two-bit result (1+1=2= (binary)10)). This extra bit is the "carry" bit, and if you build a multi-bit adder, you must take it as an additional input for the next bit slice - see full adder. The automaton starts in the state R0, and R0 says "the carry bit is zero". It then checks the character - there are 4 valid additions, and 4 invalid ones.The valid ones are 0+0=0, 1+0=1, 0+1=1, 1+1=10. The last one also sets the carry bit, which is why the automaton goes to the state R1 ("the carry bit is 1"). All other variants are wrong and lead to the error state. In R1, there are again four correct results, and 4 wrong ones. But since we now have the carry bit as an additional input, the correct results are 0+0+c=1, 0+1+c=10, 1+0+c=10, 1+1+c=11, and the other 4 are wrong. In the first case (0+0+c=1), the carry bit is consumed and we drop back to R0. And of course, once the addition is wrong, it stays wrong (which is why the error state goes to the error state with the whole alphabet). It's apparently "complex" to understand, which is why you have to ask ;-). On the other hand, it shows that verification of addition is at worst linear in the number of bits with respect to time complexity and constant with respect to space complexity. --Stephan Schulz (talk) 13:40, 27 January 2016 (UTC)

Yeah this answer gives me a sense of hope for my doubts.Could you list the four invalid ones for the state R0.JUSTIN JOHNS (talk) 06:55, 28 January 2016 (UTC)

Well, it's the combinations missing from the list I gave above: (00/1). (01/0), (10/0), (11/1). Now you list the wrong ones in R1! --Stephan Schulz (talk) 08:39, 28 January 2016 (UTC)

I think it would be 0+0+c=0,0+1+c=01,1+0+c=11,1+1+c=11 but I'm not sure.I really understood the wrong states you listed above by these two sentences you've mentioned:"the first two are the input, the last is the lower order bit of the output","so it's not performing addition, but verifying addition".Could you tell why the states in R1 are only 4 because we could also list 0+1+c=11 as a wrong state isn't it?JUSTIN JOHNS (talk) 10:01, 2 February 2016 (UTC)

I think we must first get the notation straight.The three states of the automaton are R1, R2, and error. The alphabet is a set of 8 letters, Σ = {00/0, 00/1, 01/0, 01/1, 10/0, 10/1, 11/0, 11/1}. Transitions take a state and a letter and produce a new state (which I will write (S,l ->S'). The transition table is
 Delta  | 00/0  | 01/0  | 10/0  | 11/0  | 00/1  | 01/1  | 10/1  | 11/1  |
 R0     | R0    | error | error | R1    | error | R0    | R0    | error |
 R1     | error | R1    | R1    | error | R0    | error | error | R1    |
 error  | error | error | error | error | error | error | error | error |
If the carry is 1, i.e. if you are in R1, then 0+1+c=10 (decimal 2), so indeed (R1, 01/1 -> error). You got 1+1+c=11 wrong - if c is one, then 1+1+1=11 (decimal 3), i.e. (R1, 11/1 -> R1). --Stephan Schulz (talk) 13:33, 2 February 2016 (UTC)

Wow that's really great.Now I could understand the states present in the automata and their transitions.To be honest I really understood the answer after analyzing the document many times before you have posted the answer.Also I dont' have a reliable internet connection.So sorry for checking the answer too late.It's my mistake to ask a question without properly looking the document.Anyway that's a great help and thanks for your kindness and patience.JUSTIN JOHNS (talk) 07:47, 8 February 2016 (UTC)
