Gulf Stream

Should this article mention the Gulf Stream? It is credited, or has been credited, to the mild temperature of the Scilly Islands. -24.149.185.189 (talk) 13:51, 3 February 2008 (UTC)

Scilly Isles

People who live in the isles of Scilly DO NOT like it to be called the Scilly Isles. - fonzy

OK - so what would they prefer? (I'm not saying that we should then move it to whatever they prefer, though we might - but I am curious) --Camembert

Move it to Isles of Scilly (whihc i think is the right name anyway)- fonzy

You're right - I remembered just after I typed the above. Just out of interest - do you know why they prefer that formation to "Scilly Isles"? --Camembert

unfortunaty no, maybe its just thye like being correct, like ceratin things annoy the scottish, if not said, written wrong. - fonzy

Maybe for the simple reason that Scilly Isles sounds too much like Silly Isles? - Hwebers

Well then, who really wrote this article ?

Here, here,,, I was on these islands a few weeks ago and everyone called it scilly isles. Every British person calls it this as well. Sounds like one persons opinion to me 93.97.184.173 (talk) —Preceding undated comment added 20:08, 16 April 2010 (UTC).

Miles to Kilometers

How much would be 28 miles in kilometers? Which mile is being used in the article? Sorry if the questions seem stupid to any of you. --matusz 23:06, 8 May 2004 (UTC)

Scilly Isles (reprise)

People who live on the Isles of Scilly (IOS) dont like it being called the Scilly Isles or the Scillies as it sounds like the word silly. IOS is located 28 land miles WSW off Land's End, roughly 45km or 24 nautical miles.

Tresco Photograph

In the photo labelled Tresco, is the vantage point and the land surrounding it, Tresco, or is Tresco the island with the lighthouse on it? Tim Rhymeless (Er...let's shimmy) 02:03, 9 September 2005 (UTC)

The photo is taken on Tresco, which is the foreground (Blockhouse Cottages, I think); the island in the background is St Helens, but the lighthouse is actually on Round Island beyond that. Agingjb 14:52, 13 October 2006 (UTC).

Origin of name

Anyone know the origin of the name? It's obviously a bit confusing with the "real" Sicily. --Doradus 16:28, 4 October 2005 (UTC)

Don't know the origin - I have heard it's pre-Indo-European

I believe the Romans called it Scilly, meaning "islands in the sun", so it is probably derived from the same origins as Sicily. I'm not sure how I know this, but I remember reading it somewhere, and someone telling me, plus it sort of makes sense.

Scillonia?

I've removed this

Note that the use of the name The Scilly Isles is deprecated by the locals, who prefer Scillonia.

pending a source. Morwen - Talk 11:51, 8 November 2005 (UTC)

I have heard of "Scillonia", but I am not sure how wide its use is (never have visited the islands). However, I would second the comments above that "Scilly Isles", "the Scillys/ies" are frowned upon by many people, and are shibboleths of a kind. --MacRusgail 15:17, 8 November 2005 (UTC)

Acceptable use is usually just Scilly, cf. Cornish Zillan. I think the Cornish used in the article is a calque on the English Isles of Scilly. Doire 22:48, 29 December 2005.

The Scilly Isles are a pair of round abouts in Surrey I believe and lets face it we wouldn't want to be confused with them. I dislike the phrase "The Scillies" becuase it is wrong, and it sounds stupid, it is wrong for the simple fact that there is only one place called Scilly, it is made up of lots of islands, each with their own distinct character. The sea is also Scilly so to refer to it as plural doesn't make sense. The name Scillonia is used for the phone area code. The most commonly used name is simply "Scilly".

"sui generis" status

As with the City of London the Isles of Scilly has a sui generis status within the English system of local government. Note the following two references:

Civil Contingencies Act - under "Local authorities" the Council of the Isles of Scilly is listed seperately (along with the Common Council of the City of London).

Isles of Scilly Council - "This unique nature has been recognied by its special constitutional position, known as the Isles of Scilly Clause."

As other local government pages on Wikipedia point out, the Isles of Scilly are a Unitary Authority in every sense, being administratively seperate from Cornwall, but they do not constitute a seperate county in any way.

Feel free to discuss and even prove me wrong/ammend the facts stated here!! :) David 23:09, 2 December 2005 (UTC)

Liquor laws differed in the 1930s?

I am presently reading the novella "The Death Penalty" by Leslie Charteris, part of the Saint mystery series (and published in Once More the Saint in 1932). In this book, the hero travels to the "Scilly Islands" (sic) and it is noted that due to their location they are not subject to certain British laws prohibiting liquor sales at certain hours (apparently during midday if I understand the story correctly). It's doubtful Charteris would have made this up, so if anyone can confirm dates, etc. it might be an interesting tidbit for the history section. 23skidoo 13:40, 19 August 2006 (UTC)

Gugh

According to this article Gugh is the smallest of the inhabited islands, with only three citizens. But according to the article Gugh, it's uninhabited. Which of the two articles is correct? Aecis ^{Dancing to electro-pop like a robot from 1984.} 01:28, 3 November 2006 (UTC)

There are two houses on Gugh, both are occupied for at least some of the year. Agingjb 09:29, 4 November 2006 (UTC)

Samson etc.

A recent change gives the number of inhabited islands as seven, presumably including the formerly inhabited Samson. But then St Helens, Tean, at least two lighthouses, and some of the eastern isles were formerly inhabited. Agingjb 17:04, 3 July 2007 (UTC)

The number has since been corrected, does the article need more about formerly inhabited islands (Samson is covered), possibly not. Agingjb 07:43, 26 September 2007 (UTC)

Critical comment - 30/01/2007

It's refreshing to see that there is some sort of critical comment here. I do think that perhaps the tourist 'image' of the Isles of Scilly is far too rosy at times - and the new BBC series 'An Island Parish' is indeed in many ways a testament to this.

My experience of the islands is primarily based on a dissertation project submitted in canditure for a degree in human geography back in 2004. This included two weeks intensive fieldwork and looked at the opportunities for young people growing up on the islands. I conducted nearly 20 in-depth interviews with young people between the ages of 16 to 26 from the different islands to understand their perceptions of access to housing, employment and education. This was situated in the context of research into the local economy and its dependency upon tourism as the main source of revenue. Interviews were also conducted with relevant employees of the council and the Duchy of Cornwall.

The main finding of the research was that many young people feel they have to leave the islands. This was in most cases due to a conflict between their future hopes and aspirations and the reality of limited and therefore exclusive opportunities to access employment and particularly housing. The islands also have no higher education provision forcing a migration of nearly all 16 year olds to the mainland, albeit temporarily.

What is concerning here is that The Isles of Scilly are loosing their future. If they can’t retain at least some of the younger generation, then this threatens the sustainability of the whole community as the operational viability of core services will be threatened. Indeed the school has had to adapt to a 'federated' structure to temporarily close off-island schools when the need arises due to the decline in numbers of children living in these catchment areas.

If tourism is indeed to be the strategy for economic survival, then it also needs to take into account the opportunities for young people living there and provide them with the support to stay if they want, and allow them to be innovative in securing the island’s future. This requires the commitment of all actors and stakeholders.

--Phillip Vincent 17:40, 30 January 2007 (UTC)

P.S Oh, and I would love to discuss this with anyone who is interested.

Rewrote statement on winter shutdown

The following statement has recently been added to the article:

Tourism is also a highly seasonal industry due to its reliance on outdoor recreation causing a near shutdown of the islands in winter.

which I think fails the common sense test. It surely isn't tourism that is causing the winter shutdown, but rather the absence of tourism in winter that is causing the shutdown. Put it another way. If the island tourist industry disappeared overnight, would this in itself increase activity in winter?. I've rewritten the statement to what I think was really meant:

Tourism is also a highly seasonal industry due to its reliance on outdoor recreation, and the low level of tourist activity in winter causes a near shutdown of the islands during that season.

Apologies if I've misunderstood. - Chris j wood 12:23, 1 February 2007 (UTC)

Incidentally, it would be really good to have either elaboration or a source (or even better both), for that statement. 'Near shutdown' has a whiff of POV about it, and in any case probably means quite different things to different people depending on their background. For example, does the electricity supply shut down in winter? (I'm pretty sure it doesn't, but if I lived in large swathes of the developing world that would be one of my criteria for near shutdown). Likewise, do the 24 hour street markets shutdown? (again, I'm pretty sure the islands don't have 24 hour street markets, but if I still lived in Hong Kong that might be what I would read into 'near shutdown'). I think what I'm saying in an overly long-winded fashion is that we need some objective examples of what is meant by near shutdown. -- Chris j wood 12:37, 1 February 2007 (UTC)

...

Cheers Chris, that makes sense to me.

In a tangible sense, there are far fewer visitors to the islands in winter. If you look at the IOS Intergrated Plan for example, this had a concern for expanding the tourist season outside of the busy summer months. Also in my own research I was led to believe that many of the locals who run tourist businesses go on holiday themeselves over the winter months so this doesn't disrupt their earning capacity for the rest of the year. It would be intersting to check out the booking periods for tourist accomodation actually - I think this would provide a better way of accessing whether many tourist providers hope to attact people during the winter.

The following article by Butler was a review of seasonality in the tourist industry more generally and this spoke explicitly about how previous research had failed to see seasonality outside of a business context, as its implications reach far beyond this into issues of community sustainablity.

Butler R (2001) 'Seasonality in Tourism: Issues and Implications', in T Baum, S Lundtorp (eds) Seasonality in Tourism, Pergamon, Oxford, pp. 5-23.

'Near shutdown' is as you say ambigious, but I felt this reflected the way that the young people I spoke to felt about the islands in winter. They often complained that it was boring to be at home during this time, with fewer people around and less chance to get out because of the weather etc.

I agree, its an important point that does need clarification because its integeral to the debate of economic mono-dependency and how this affects the community in a broader sense.

--Phillip Vincent 13:22, 3 February 2007 (UTC)

"White" People?

“…and the ethnic makeup of the islands is almost exclusively White,” is rather inarticulate and barbaric. In the 21st Century is “white” still acceptable as an ethnic classification? I should hope not. I vote to alter this to something more scholarly (such as Caucasian). If it is unacceptable to use “black” to refer to a group of people, then how in the name of logic can it be acceptable to use “white” in this case? The PC movement has rendered the average writer of the English language incapable of seeing the ridiculousness of this misnomer. —Preceding unsigned comment added by 163.1.236.22 (talk)

White is the standard term in British English Black is also standard in British English - Caucasian refers to someone from the Caucasus . DuncanHill 11:03, 22 August 2007 (UTC)

The makeup, as far as I can tell, is mostly white Cornish (yes, Cornish IS alloted a census code, but does not appear as an option) or white English. --MacRusgail 19:11, 24 September 2007 (UTC)

Oh my... read the Daily Mail by any chance? Political Correctness gone mad hahah 93.97.184.173 (talk) —Preceding undated comment added 20:11, 16 April 2010 (UTC).

Which of the following statements is true?

The people of the islands have a genetic link to the ancient British tribal people who inhabited the islands long before the arrival of the Celts or Romans.

Whilst there is little evidence to substantiate the claim, it is sometimes rather tenuously suggested, that the early inhabitants of the islands may have had a genetic link to the "Ancient British" who inhabited the islands long before the arrival of the Celts or Romans —Preceding unsigned comment added by 217.43.102.175 (talk) 20:55, 31 October 2007 (UTC)

I guess both statements must be true then.

---

Is "White" an ethnic group? Don't we have to differentiate among, say, Celts, Anglo-Saxons, Finns, and so forth?

Talking islands? Now that's just Scilly

I changed "It is not known at exactly what time the islands stopped speaking Cornish" to "It is not known at exactly what time the islands' inhabitants stopped speaking Cornish."

Three suggestions for edits I don't feel qualifed to make:

1. How is King Olaf visiting a seer there evidence that the Isles once were larger and many of them joined?

2. Can the reference to "Some of the Cornish language placenames also appear to reflect past shorelines, and former land areas" be supported with some examples?

3. The bit about the Isles attracting rare birds is very interesting but a little vague. Any examples?

    JamestownArarat (talk) 05:43, 21 November 2007 (UTC)

1 - it isn't. No one said so. 2 - Yes. 3- no idea, but could be expanded. Not a twitcher myself. --MacRusgail (talk) 18:47, 5 January 2008 (UTC)

3 I suppose a link to http://www.scilly-birding.co.uk/ could be added. Agingjb (talk) 20:27, 29 September 2008 (UTC)

Strange sentence

In the middle of the "Middle-Ages" paragraph is the following sentence:

In 1375, Boreman, with 28 mariners, was captured in the Isles of Scilly in a barge of Normandy by Fulbroke, Borde and others and brought to Bristol as prisoners.

Can anyone add any detail or framing to it? I've had a good search and failed to find out who "Boreman", "Fulbroke" or "Borde" were. I'm going to remove this unless someone can identify the relevance.

Cheers,

I've done a bit of cleaning up, removing forced image sizes which override user settings, added a bit on Ennor and general tinkering. Could do with a good copy edit, I've only fixed a few of the worst atrocities (month of October = October) jimfbleak (talk) 14:48, 15 October 2008 (UTC)

Transport

The article has recently been edited to change the list of Skybus destinations, removing many of them. As far I can tell, the original list was more correct Agingjb (talk) 10:47, 27 January 2010 (UTC)

Samson

The table of islands had a footnote, saying "[1]Inhabited until 1855" but the marker in the table had been removed. I restored it. Rojomoke (talk) 15:37, 1 October 2009 (UTC)

Driving tests

I've recently heard that people travel to the Isles of Scilly to learn to drive, because it's so easy to pass your test there, and so you can gain a full UK licence in a matter of days. Indeed, [1] states that IoS has the highest pass rate for car tests in the country. Apparently there are no roundabouts, and some other features are absent though I forget which.

Is this notable enough for something to be written in the article about it? Moreover, can anybody find sources to back these claims? -- Smjg (talk) 00:18, 24 July 2010 (UTC)

Move request to move iOS (Apple) to IOS

Where are these islands?

Simpley put, put a real map in this article. Showing me pictures of islands surrounded by water doesn't help in gaining the ability to point out these islands on other maps/a globe. Without showing the islands in relation to Britain or Europe, one cannot fully understand where these islands are.

Per your valid request I've added a map. Dr. Blofeld 07:58, 18 September 2010 (UTC)

The whole of southern England has been steadily sinking in opposition to post-glacial rebound in Scotland: this has caused the rias (drowned river valleys) on the southern Cornish coast, e.g. River Fal and the Tamar Estuary.

This isn't actually what is happening, South East England is sinking while the south west is relatively stable, to such an extent that the OS use the harbour wall at Newlyn is used as the gauge of sea level and tidal activity across the whole country. (Ordnance_Datum). Nor were the Tamar or Fal estuaries formed via the South West sinking, the event was a global sea level which flooded the then lower valleys with water, leaving the Rias we see today. Should I therefore remove this piece of text?Jackdann88 (talk) 22:00, 7 October 2010 (UTC)

Lead.

Made a few additions and tweaks to the lead, as I'm not the most confident editor I'd be pleased if someone could review my additions. I was amazed the article wasn't tagged for not conveying enough info in the lead actually; very sparse and sad. Hope I've helped. --Τασουλα (talk) 20:31, 20 May 2012 (UTC)

Anglia et Cornubia/English or Cornish

These edits here add some useful info but imo mark a distinction that is not as clear cut as implied by the wording. I'm not sure for example how accurate this statement is - "Before the Tudor period, laws were typically designated as taking effect in Anglia et Cornubia". This is definitely the case with some laws, but I'm not sure "typically" is correct, and no source has been added to confirm or clarify the point. Also, the constitutional status of Cornwall is in fact not "a matter of some debate", if that's meant to refer to the supposedly dubious nature of its current connection to England (all the "Duchy not a county" stuff). Even the debate around any future changes is relatively limited in scope if one is looking at mainstream discussion. We are not talking about Scotland/UK or Catalonia/Spain here. Also the reference to the people being "either Cornish or English" assumes a clear separation and distinction that not everyone makes. N-HH talk/edits 21:35, 29 November 2012 (UTC)

Apologies, but I've gone ahead and taken the additions out in their entirety. I know the material could perhaps be edited, and citation tags added, but there are overall too many problems with much of it. In addition to the above points, it contained lots of commentary and apparent value judgments, eg "a similar situation exists today", "it is sometimes rather tenuously suggested", "subjective observations suggest that", "young indigenous Cornish are increasingly underrepresented" (and what does the latter mean anyway - that their numbers are falling, or that the true number is not recognised?), as well as strange statements such as that Poles have been "brought in". Plus, for example, notes about the history of Cornwall are not relevant to a section about "National government". N-HH talk/edits 14:35, 1 December 2012 (UTC)

The Cornish are an ethnic group... you'll find this attested to in numerous foreign publications. Of course, the British establishment has difficulty separating out the various strands of so called British culture, and conflates them. Of course, in this case, certain folk do not wish to admit that the Cornish exist, or confuse them with a county identity e.g. Yorkshire.--MacRùsgail (talk) 20:04, 4 December 2012 (UTC)

Where in the above did I say they were not, deny that the Cornish are often taken as distinct from the English, or deny anyone's existence outright? Where in the above have you addressed - let alone even acknowledged - any of my multiple points, which go way beyond the point about Cornish/English, before simply restoring all your additions verbatim? N-HH talk/edits 23:01, 4 December 2012 (UTC)

I've added some sources and properly presented detail about demographics (based vaguely on the material that was added initially), but have again removed much of the conjecture, commentary, and barely relevant and unencyclopedic theorising and speculation about population and politics. There may be some debate to be had about that, but can we please have it? Brief ramblings about alleged ethnic denialism and the "British establishment" don't count and are not sufficient justification for it to be blindly reinserted. N-HH talk/edits 09:19, 6 December 2012 (UTC)

Mass revert and "anglocentrism"

This edit has reverted, en masse, a series of recent changes, without any talk page comment. I haven't looked through the differences in detail, but an edit summary that justifies reversion of material about a place that's part of England and not part of any serious territorial dispute by citing "anglocentrism" as a criticism immediately raises concerns. To take something from the top of the page, I'm not sure that the new map wasn't better, since it showed the location of the islands in a context that probably makes sense to a broader readership. Can we please not drag this page into a ridiculous ethno-nationalist war? N-HH talk/edits 10:17, 13 December 2012 (UTC)

The West Country Challenge

Would you like to win up to £250 in Amazon vouchers for participating in The West Country Challenge?

The The West Country Challenge will take place from 8 to 28 August 2016. The idea is to create and improve articles about Bristol, Somerset, Devon, Cornwall and the Isles of Scilly, Dorset, Wiltshire and Gloucestershire, like this one.

The format will be based on Wales's successful Awaken the Dragon which saw over 1000 article improvements and creations and 65 GAs/FAs. As with the Dragon contest, the focus is more on improving core articles and breathing new life into those older stale articles and stubs which might otherwise not get edited in years. All contributions, including new articles, are welcome though.

Work on any of the items at:

• Core articles
• Missing article hotlist
• Missing photograph hotlist

or other articles relating to the area.

There will be sub contests focusing on particular areas:

• Bristol (Day 1-3)
• Cornwall and Scilly (Day 4-6)
• Devon (Day 7-9)
• Dorset (Day 10-12)
• Gloucestershire (Day 13-15)
• Somerset (Day 16-18)
• Wiltshire (Day 19-21)

To sign up or get more information visit the contest pages at Wikipedia:WikiProject England/The West Country Challenge.— Rod ^talk 16:10, 18 July 2016 (UTC)

In what way is the flag of the islands "unofficial"?

Flags can't really be "official" in the UK. The Cornish flag is just as "unofficial" as the Scillonian flag. They're both registered with the Flag Institute, which is as close as a flag can get to being official. I'll change the article accordingly. --Inops (talk) 11:39, 25 July 2017 (UTC)

I suspect this is a thing of the past. Does anyone have information to the contrary? Brownturkey (talk) 20:08, 14 August 2018 (UTC)

According to the Duchy of Cornwall, which owns most of the islands, "Dating back to the 1860s, flower farming remains an important part of the local economy to this day" but "tourism is the most important industry – accounting for more than 85 per cent of the local economy and employing more than 70 per cent of the islands' population." See this link. Of course, employment in tourism is often both part-time and part-year, so many of those employed in tourism may have other jobs. DuncanHill (talk) 22:57, 14 August 2018 (UTC)

Climate section (2019)

A number of very dubious claims in here, typical of pages where locals edit in order to make inflated claims about their climate. 1) Removed "warm" in front of Koeppen classification. "Warm" is subjective, and has no place in the named definition. 2) Removed the "borders on a subtropical climate" claim. This was originally put in by mixing definitions. The Trewartha definition has a much lower bar for subtropical than does Koeppen. Koeppen requires the mean temperature in the warmest month to be at least 22C. For Scilly, that is about 5-6C short. So not even close to bordering on subtropical. In Koeppen, even Sydney does not quite reach subtropical status, so it is nonsensical and misleading to claim Scilly borders on it. 3) Removed the "Mediterranean influence" claim. Scilly's summers are still too wet to claim any kind of Mediterranean classification. — Preceding unsigned comment added by 202.21.130.193 (talk) 20:04, 28 December 2019 (UTC)

The subtropical silliness seems to be rearing its head again with tag-team edit waring by a couple of users who keep adding in dubious claims without providing sources or discussing here. https://en.wikipedia.org/w/index.php?title=Isles_of_Scilly&oldid=1258029371, https://en.wikipedia.org/w/index.php?title=Isles_of_Scilly&oldid=1258027151, https://en.wikipedia.org/w/index.php?title=Isles_of_Scilly&oldid=1258027151, https://en.wikipedia.org/w/index.php?title=Isles_of_Scilly&oldid=1258025718, https://en.wikipedia.org/w/index.php?title=Isles_of_Scilly&oldid=1258025370, https://en.wikipedia.org/w/index.php?title=Isles_of_Scilly&oldid=1257035361, The Isles are not subtropical under any classification. Not even Trewartha (which is not the accepted climate standard in any case), under the latest update of the classification system. See: https://rgs-ibg.onlinelibrary.wiley.com/doi/abs/10.1111/geoj.12458 . Two users are peddling disinformation and edit warring, possibly COI?, to reclassify the Isles as subtropical without discussing here or producing any relevant reliable sources, instead littering the page with vague, dubious references, and making scattergun references to WP policies that don't apply here. 86.184.52.46 (talk) 20:20, 17 November 2024 (UTC)

Okay, please walk me through how Trewartha does not classify the Isles of Scilly as subtropical. You linked an article behind a paywall (later edit: I have accessed the article, which also claims on pg. 5 that subtropical climates are defined by 8 months above 10C, not supporting your claim), but all the sources I have say that Trewartha classifies climates as subtropical when they have 8 months over 10C. This does cause a lot of silliness; Bordeaux and Istanbul become "humid subtropical" under Trewartha, while a city like Diyarbakır becomes temperate. But that is the rule of Trewartha, and we are not here to cherry-pick information because we don't agree with it. I certainly don't, in fact I don't agree with how subtropical as a term is used in any climate classification, but it is what it is. And this has nothing to do with Trewartha not being the accepted standard, as it is an accepted standard as a notable climate classification, and nobody is arguing for Köppen's removal (which would indeed be the accepted standard, if we had to pick one).

Unless your argument rests on the assertion that the Isles don't have 8 months over 10C, in which case, they do, they just do, I don't see what that argument is about:

As above, please read "See: https://rgs-ibg.onlinelibrary.wiley.com/doi/abs/10.1111/geoj.12458 ." Your fringe theory assertions does not reflect the latest Trewartha classification. You've not provided any RS evidence that Isles of Scilly are "subtropical". You are edit warring. 86.184.52.46 (talk) 16:37, 18 November 2024 (UTC)

I accessed the paper from another source and read it. On page 5 it clearly states:

C: Subtropical climates, 8 to 12 months >10°C

The paper you're providing supports my position. None of this material is fringe, please stop. Uness232 (talk) 19:18, 18 November 2024 (UTC)

Despite numerous opportunities you've not provided one RS source that states that IOS has a subtropical climate. Why? Because no reputable academic, climatologist, geographer etc would ever claim this since it is patently false. You are clearly a SP bad actor promoting fringe climate claims. I'm not engaging further until you play by WP rules and provide a RS. 86.184.52.46 (talk) 20:21, 18 November 2024 (UTC)

What? How have I not provided RS? Uness232 (talk) 22:23, 18 November 2024 (UTC)

By not providing a RS to back up your fringe claim. I have provided RS to confirm SI climate is not subtropical. You are reverting this for no good reason and without reason - this is vandalism. 86.184.52.46 (talk) 22:41, 18 November 2024 (UTC)

1 - You are removing sourced material without explanation which is vandalism.

2 - I've sourced Trewartha's book. Clearly you haven't read his chapter on subtropical climates which clearly states marine climates in this category must be frostless. (Trewartha, Glenn Thomas (1968). An Introduction to Climate. McGraw-Hill,. p. Ch: Subtropical climates. ISBN 9780700651481.)

3- If you revert again I will report your 3RR and vandalism. 86.184.52.46 (talk) 22:44, 18 November 2024 (UTC)

1) I am explaining all of my edits.

2) No, I have not seen Trewartha make this claim, and this seems incredibly unlikely considering the only climates that are completely frost-free are tropical ones, which subtropical is distinct from.

3) Okay.

About your claim that I have not provided RS, what are the sources I provided to you then? Are they not reliable? and the one you provided that ended up supporting my point? Did you give me an unreliable source? Uness232 (talk) 22:51, 18 November 2024 (UTC)

I suggest you read Trewartha's book! 86.184.52.46 (talk) 22:54, 18 November 2024 (UTC)

I can not read it in its entirety at this moment, of course. Do you have a quote, at least a page number? I can certainly look it up. Uness232 (talk) 23:02, 18 November 2024 (UTC)

Sure: read the chapter "Subtropical climates", pages 330-362. 86.184.52.46 (talk) 23:14, 18 November 2024 (UTC)

Trewartha's book does not have information about Subtropical climates by pg. 330-362. In fact 330 corresponds more or less to the start of the "humid microthermal" chapter. Uness232 (talk) 23:24, 18 November 2024 (UTC)

Read the edition I quoted in the reference. 86.184.52.46 (talk) 23:34, 18 November 2024 (UTC)

I'm literally looking at it in front of me. The page numbers are correct. 86.184.52.46 (talk) 23:34, 18 November 2024 (UTC)

Sorry, I can't find the 4th edition online, do you have a quote?

I'm asking specifically because this would change how we would approach climate classification here, in general. We have long considered 8 months over 10C the threshold on Wikipedia (see Trewartha climate classification#Scheme), and this would be genuinely new information for all of us. This would also mean neither Bordeaux nor Istanbul (among others) would qualify as subtropical under Trewartha, although we have long considered both as such. Uness232 (talk) 23:44, 18 November 2024 (UTC)

The specific quote is "marine climates in this category must be frostless". Incidentally, it's also in all 'A level' geography syllabuses and text books. It's not hard to find if you're a geography teacher. I've made an RFC to ask for more eyes to look at this. 86.184.52.46 (talk) 23:49, 18 November 2024 (UTC)

St Agnes southernmost point?

The article states: One of the islands, St Agnes, is the most southerly point in the British Isles, being over four miles (six kilometres) further south than the most southerly point of the British mainland at Lizard Point.

It seems, however, as there are within this group other islands (or islets) further south. Why is St Agnes defined as the southernmost point? Fomalhaut76 (talk) 19:42, 26 February 2024 (UTC)

It's also demonstrably not true even considering the rest of the Scilly Isles' associated minor outcrops. The islands of Les Minquiers, part of the Bailiwick of Jersey, are undoubtedly the most southerly islands in the British Isles. The Channel Islands are part of the British Isles but not the UK or Great Britain, which is perhaps what the author of this sentence was conflating? 2600:1700:5890:9C70:59C5:41D6:BE83:25FC (talk) 09:27, 11 March 2024 (UTC)

RfC about whether Isles of Scilly are "Subtropical"

Trewartha's Book in which he defines his climate classification system clearly states marine climates in this category must be frostless. (ISBN 9780700651481 Chapter: Subtropical climates, pages 330-362). Met Office data (https://www.metoffice.gov.uk/research/climate/maps-and-data/uk-climate-averages/gbgebz4kn) shows the Isles of Scilly are not frostless. So how can the Isles of Scilly be considered "subtropical". Can anyone provide academic comment and/or third-party reliable sources that specifically claim the Isles of Scilly are subtropical? More editors looking at this would be helpful. 86.184.52.46 (talk) 23:46, 18 November 2024 (UTC)

• Yes, but only according to Trewartha. According to the Köppen climate classification, the Isles do not have a subtropical climate. However, the Trewartha scheme (see [2] and [3]) considers climates subtropical when they have 8 months over 10C, which is what this dispute was about. Whatever our personal opinions on this, this is the rule that is on every source I could find. Since the Isles have 8 months over 10C, they are subtropical according to Trewartha.
  The editor that started this dispute insists, instead, that marine subtropical climates have to be frost-free, which I have not seen any evidence for in any source or climate classification. They have apparently found a quote in Trewartha's 4th edition of An Introduction to Climate (the only edition that I could not reach) saying so. If that is indeed true, we need to reevaluate how we use the Trewartha system on Wikipedia in general, because articles like Bordeaux and Climate of Istanbul would have to have their climate classes changed, as non-frost free climates with 8 months over 10C. This can not be done only for the Isles however. :Uness232 (talk) 00:03, 19 November 2024 (UTC)

  You are correct. You should revaluate Bordeaux and Istanbul since these are also not subtropical under any climate classification and no sources or editors other than you appears to be claiming they are. I notice your similar tactics on the Budapest talk page where you tried to add the fringe theory content, claimed Quo, and other editors caught on and called you out. There's a pattern of editor here: [[4]].

  The issue here is your unsourced fringe theories. If you believe otherwise, find a source by a reputable climatologist or academic paper that clearly states Isles of Scilly are subtropical; Budapest is subtropical; Bordeaux is subtropical; Istanbul is subtropical. Etc. 86.184.52.46 (talk) 03:00, 19 November 2024 (UTC)

  I don't know what to tell you. We classify climates using empirical methods on Wikipedia. This means the systems have rules and are not just opinions. Köppen has a different rule for subtropical, Trewartha has a different one. You can read both pages, look at their sources, and see for yourself how Bordeaux and Istanbul are subtropical. Uness232 (talk) 03:05, 19 November 2024 (UTC)

  Find a source to back up your claim! This is no different to any other WP article. What you are doing is misrepresenting the climate criteria classification by cherry picking the criteria that support your fringe theory and feigning ignorance of any criteria that scupper your fringe theory. You are not discussing or trying to reach consensus, you are simply repeating the same point in the hope other editors will give up. And you are refusing to engage in meaningful discussion not just here, but also here: https://en.wikipedia.org/wiki/Talk:Budapest#Climate. 86.184.52.46 (talk) 03:09, 19 November 2024 (UTC)

Procedural Close. An RFC is supposed to be presented neutrally WP:RFCNEUTRAL, going So how can the Isles of Scilly be considered "subtropical" does not seem to be a neutral summary of the dispute. Furthermore, I do not think the RFC process is intended to be used to shop for sources per WP:RFCNOT. Brocade River Poems (She/They) 05:35, 19 November 2024 (UTC)

Thank you for raising these points. While I understand your concerns, I respectfully disagree for the following reasons:

1. Neutral Presentation of the Dispute (WP ): The phrasing of the RFC question, while possibly imperfect, directly addresses the central issue under discussion—whether the Isles of Scilly can reasonably be considered subtropical based on reliable sources. Phrasing it this way invites participants to consider and evaluate the strength of evidence on both sides. If you have a suggestion for a more neutral wording that maintains focus on the dispute, I’d welcome it. However, I don’t believe the current phrasing violates the principle of neutrality, as it does not presume the outcome of the discussion.
2. Purpose of RFCs (WP ): While the RFC process is indeed not a tool to "shop for sources," it is a legitimate way to resolve content disputes when editors disagree about the interpretation or applicability of existing sources. In this case, the RFC seeks community input on how to handle the claim about subtropical climate, which hinges on source reliability and weight. This is precisely the kind of editorial judgment that RFCs are designed to help with.
3. Progressing the Discussion: The RFC serves to clarify and formalise the dispute in a way that solicits broader input, which is essential given the current impasse. Without it, the discussion risks going in circles or stalling entirely. The goal is to reach a resolution based on community consensus, informed by policy and evidence. This is not only constructive but necessary to avoid prolonged disagreement.

In summary, I believe the RFC is both appropriate and necessary to move the discussion forward. If you have suggestions for improving the RFC's wording or approach, I’d be happy to collaborate to ensure it meets the highest standards of neutrality and utility. 86.184.52.46 (talk) 11:06, 19 November 2024 (UTC)

Discussion

ChatGPT produced this:

ChatGPT said: ChatGPT Under the Trewartha climate classification, the Isles of Scilly would not be considered subtropical. The Trewartha system refines the Köppen classification, emphasizing temperature ranges and growing seasons to delineate climates more precisely.

For a region to qualify as subtropical under Trewartha, it typically requires:

At least 8 months of the year with mean temperatures above 10°C (50°F), which is the threshold for warm-temperate or subtropical climates. Winters that are mild, with no significant frost. Isles of Scilly Climate Overview: The Isles of Scilly have a maritime climate characterized by mild winters and cool summers, heavily influenced by the surrounding Atlantic Ocean and the Gulf Stream. Mean temperatures for the warmest months (summer) are around 16–20°C (61–68°F), and for the coldest months (winter), they are typically 7–9°C (45–48°F). They likely do not meet the 8-month criterion for mean temperatures exceeding 10°C. Conclusion: The Isles of Scilly would be classified as oceanic (Do) in the Trewartha system, not subtropical. However, their exceptionally mild climate for their latitude gives them a subtropical "feel," especially in their flora and moderated seasonal changes. 86.184.52.46 (talk) 01:13, 19 November 2024 (UTC)

ChatGPT is not a reliable source, and is wrong here (about whether IoS meets criteria, not about the criteria itself). If you look at the daily means and count the months:

you can see that the Isles do meet the 8 month criterion. Uness232 (talk) 02:57, 19 November 2024 (UTC)

You've missed the point. The point is why would a large language model state those comments? What sources is it using. Have you tried interrogating Chat GPT to find out why? 86.184.52.46 (talk) 03:01, 19 November 2024 (UTC)

I don't know, and I'm not sure I particularly care. We don't use ChatGPT as a source in Wikipedia; it often hallucinates information. Uness232 (talk) 03:03, 19 November 2024 (UTC)

It provides sources, if you ask for them. BTW where did you get the "daily mean" figures for in your chart. They are not from the Met Office. The Met Office doesn't use 'daily mean' data. And have you checked which average calculation method Trewartha uses in his classification? Can you reference that? 86.184.52.46 (talk) 03:17, 19 November 2024 (UTC)

Please see the bars at the bottom of the table.

Met Officecis the source for all the data here. Except dew pointPAper GOL (talk) 14:43, 19 November 2024 (UTC)

But it's not frost free. You keep deliberately omitting the one criteria that scuppers your claims for Isles of Scilly, Budapest, Bordeaux and Istanbul. Have I missed any?Are there any more cities you intend to reclassify subtropical? 86.184.52.46 (talk) 03:05, 19 November 2024 (UTC)

I have never seen a verifiable source that says only frost-free climates can be subtropical. Not even the paper you provided said that; not even ChatGPT! You claim to have a copy of the 4th edition of Trewartha's book and that this information is only accessible in that edition, well that's just not verifiable! I have sources here. [5][6] None of them mention this rule, conveniently; and I have a hard time believing Trewartha simply made this rule for his book's 4th edition, omitted it from everything else so that no modern source can back it up. Uness232 (talk) 03:09, 19 November 2024 (UTC)

It is verifiable - I have the book in front of me. Just because you don't, can't or won't verify the source (because it doesn't fit your fringe theory) doesn't mean it isn't verifiable. That's not how WP works. And do bear in mind you are basing you fringe theory on Trewartha's book - and it appears you haven't read Trewartha's book because if you had, you'd know full well it requires marine locations to be frost free! Go to a library. Read the book. 86.184.52.46 (talk) 03:13, 19 November 2024 (UTC)

Show me the source which states that subtropical climates should be frost-free.

Because with your POV, even Houston is not subtropical because it experiences frosts.PAper GOL (talk) 14:47, 19 November 2024 (UTC)

Trewartha's book states "marine climates in this category must be frostless" to be considered subtropical under Trewarth's classification. 86.184.52.46 (talk) 16:25, 19 November 2024 (UTC)

Under what parameters is Houston not marine? Forget Houston, New Orleans wouldn't even be subtropical, as it also is not frost-free. Are you perhaps confusing frostless in a more technical sense 'does not have a month that averages a frosty night' (so no average daily low below 0C in any month), with the colloquial sense of frost-free? Because some tropical climates, like Miami, are also not frost-free! Being frost-free usually requires mean temperatures above 20C every month of the year: no subtropical climate can reach this, because at that point, they are past the tropical limit of 18C in the coldest month.

• Are there any actual sources on the Isles of Scilly either way? Interpreting and applying general sources about climate classifications to a particular area is WP:OR. If there are no sources, the article should not state it either way. CMD (talk) 03:09, 19 November 2024 (UTC)

  Agreed! 86.184.52.46 (talk) 03:10, 19 November 2024 (UTC)

  @Chipmunkdavis Interpreting and applying general sources about climate classifications to a particular area is WP:OR. No, it is WP:CALC, because the calculation for these can be verified by anyone. See the source and verify it for yourself. Uness232 (talk) 03:11, 19 November 2024 (UTC)

  Applying climate classifications is not CALC, they are subjective and partially qualitative categories, as shown by there being multiple ways to classify them. I can't find anything in that source about the Isles of Scilly. CMD (talk) 03:13, 19 November 2024 (UTC)

  Agreed. 86.184.52.46 (talk) 03:13, 19 November 2024 (UTC)

  @Chipmunkdavis No they are not, empirical climate classifications are entirely quantitative and not subjective, as long as which climate classification it is is clear. This is the case for every climate section: if we were to judge this as OR, we would have to remove climate categories from NYC, LA, and Paris. None of them have specific information as a source, but are sourced to the general rules of Köppen. Uness232 (talk) 03:16, 19 November 2024 (UTC)

  Those removals sound like a good idea. Paris isn't even sourced to that. CMD (talk) 03:18, 19 November 2024 (UTC)

  I don't think you understand. This would affect almost EVERY climate article. Madrid, Ankara, Beijing, Tokyo... the list goes on and on. It has been silent consensus for years that this is CALC, and this would be an insanely time-consuming change. I would at least start a different RfC for that. Uness232 (talk) 03:21, 19 November 2024 (UTC)

  No, it would more likely only affect pages where dubious unsourced climate claims have been added based on WP:OR? This one https://en.wikipedia.org/wiki/Talk:Budapest#Climate is a case in point. Surely you can appreciate it would be best practice to properly source climate claims using reliable third party sources from academic papers, climatologist, national climate bureaus etc, and not one editor's subjective calculations? 86.184.52.46 (talk) 03:24, 19 November 2024 (UTC)

  Okay. Ignore all of my examples and arguments and just claim random stuff, great. I have not even changed half of these pages, and a lot of them have been stable for YEARS. Uness232 (talk) 03:29, 19 November 2024 (UTC)

  I do understand, I have seen climate OR added to many articles, and removed them at times, although I haven't clocked it as a widespread problem before. On this specific RfC, no source has been presented verifying that the Isles of Scilly are subtropical (or not). CMD (talk) 03:32, 19 November 2024 (UTC)

  But we as editors who work on this do not consider it OR, and there is no reason for it to be OR because it is completely verifiable. See the short discussion over at Talk:Köppen climate classification#Lack of sourcing. And it is not a "widespread problem". I don't see how it is a problem because anyone can verify it. WP:CALC specifically states: Routine calculations do not count as original research, provided there is consensus among editors that the results of the calculations are correct, and a meaningful reflection of the sources. Basic arithmetic, such as adding numbers, converting units, or calculating a person's age, is almost always permissible.

  Basic arithmetic is ALL that is required to determine a Köppen/Trewartha type (no subjective interpretation involved), and as long as the source for the rules are given, this falls squarely under WP:CALC. I can literally demonstrate if you wish. Uness232 (talk) 03:38, 19 November 2024 (UTC)

  It's not WP:Calc. https://en.wikipedia.org/wiki/Talk:Isles_of_Scilly#c-Chipmunkdavis-20241119031300-Uness232-20241119031100 86.184.52.46 (talk) 03:40, 19 November 2024 (UTC)

  Basic arithmetic is CALC, therefore it is CALC. Uness232 (talk) 03:42, 19 November 2024 (UTC)

  It's not WP:Calc. https://en.wikipedia.org/wiki/Talk:Isles_of_Scilly#c-Chipmunkdavis-20241119031300-Uness232-20241119031100 . And it's not basic arithmetic since it's your interpretation of the data and the data has been cherrypicked. Find one RS source from a climatologist to back up your claim. If you can't, maybe that should tell you something. 86.184.52.46 (talk) 03:52, 19 November 2024 (UTC)

  The reason for it to be OR is that there is no source. That link points to another instance of someone noting edits are unsourced. There is a wide gulf between calculating a person's age and the long explanation for the Kabul research provided in the linked discussion. CMD (talk) 03:47, 19 November 2024 (UTC)

  @Chipmunkdavis Well, in every discussion prior to this, as long as the rules are sourced, this has been accepted as the "correct" way. Per WP:CONLEVEL, we are at the wrong place to discuss this. Uness232 (talk) 03:53, 19 November 2024 (UTC)

  The right place to discuss this page is this talkpage. WP:V hasn't been met, let alone WP:DUE. CMD (talk) 03:57, 19 November 2024 (UTC)

  How is WP:DUE even relevant here? Uness232 (talk) 04:11, 19 November 2024 (UTC)

  DUE is relevant everywhere. The article is promoting a classification we have not found a single source for. CMD (talk) 05:26, 19 November 2024 (UTC)

  These are Köppen types. Nobody claimed IoS was subtropical per Köppen. Uness232 (talk) 04:14, 19 November 2024 (UTC)

  Again, you are deliberately missing the point. The point is, as I'm sure you are aware, there are no sources to support your claim that the Isles of Scilly are subtropical. No one has claimed this. Ever. 86.184.52.46 (talk) 04:22, 19 November 2024 (UTC)

  The Business Insider article that you put in the article to claim that Ios is not subtropical, actively claims IoS to be subtropical. So yes, there are absolutely people who say this. Uness232 (talk) 04:25, 19 November 2024 (UTC)

  You are again misrepresenting. I referenced the Business Insider as an example of how tourism has incorrectly labelled the islands subtropical. The Business Insider is perpetuating a myth with incorrect information. Likely sourced from Wikipedia! So sorry that particular nuance was lost on you. 86.184.52.46 (talk) 04:29, 19 November 2024 (UTC)

  What? That is absolutely not how sourcing works on Wikipedia. You can not source something to claim its opposite. That is actual OR! Uness232 (talk) 04:31, 19 November 2024 (UTC)

  No. That is an editor not reading an edit. 86.184.52.46 (talk) 04:32, 19 November 2024 (UTC)

  Reminder: You have nothing to back up your claim. You have no consensus. 86.184.52.46 (talk) 04:33, 19 November 2024 (UTC)

  Madrid, Ankara, Beijing, Tokyo all have frosts. 86.184.52.46 (talk) 04:16, 19 November 2024 (UTC)

  Not claiming any of those (except Tokyo) to be subtropical. Please read. Uness232 (talk) 04:17, 19 November 2024 (UTC)

  Good. Then they are not relevant to this discussion. Let's focus on getting you to add some sources to back up your claims that Isles of Scilly and Budapest are sub tropical. 86.184.52.46 (talk) 04:21, 19 November 2024 (UTC)

  I put them there to illustrate a different point, but they were absolutely relevant. Uness232 (talk) 04:29, 19 November 2024 (UTC)

  Word-salad. You have nothing to back up your claim. You have no consensus. 86.184.52.46 (talk) 04:32, 19 November 2024 (UTC)

  I see you are claiming New York has a humid subtropical climate. Can you provide a source for that? 86.184.52.46 (talk) 03:20, 19 November 2024 (UTC)

  I am not. If it was up to me I would not call Scilly, NYC, Istanbul, Bordeaux etc subtropical. I am just trying to explain why they are so according to Köppen and/or Trewartha, which are empirical classifications with set calculations and set names for climates. This is how things have been done for more than a decade. Please understand. And if you want to change that, go to a more general venue and get consensus from the entire community: I wouldn't be against it. Uness232 (talk) 03:24, 19 November 2024 (UTC)

  You claim "empirical classification with set calculations and set names for climates". And yet the mean temperatures in your chart are not sourced from the reference given? Your "set calculations" are in fact your WP:OR calculations. You've not even checked whether these classifications systems use mean, median or modal averages or referenced that fact. "This is how things have been done for more than a decade" - that's a flat Earth argument. Where is your consensus? Can you point to any other editor who agrees with you on any of the talk pages for any of these articles? 86.184.52.46 (talk) 03:28, 19 November 2024 (UTC)

  You've not even checked whether these classifications systems use mean, median or modal averages or referenced that fact.

  What? The papers for the rules of Köppen/Trewartha clearly state that they use daily means. You would know this if you've read any.

  Where is your consensus? Can you point to any other editor who agrees with you on any of the talk pages for any of these articles?

  Read WP:Silent consensus. Uness232 (talk) 03:33, 19 November 2024 (UTC)

  So that's a no. You don't have any consensus. What I do see is you trying to rerun this discussion - https://en.wikipedia.org/wiki/Talk:Budapest#Climate - where you did not gain consensus and your edits were not accepted by other editors. The arguments are exactly the same for this page as Budapest and all the other locations that have been raised. You have no consensus for your fringe theory, and all these fringe and unsourced "subtropical" climate claims should be removed. They are not provable and not encyclopaedic. 86.184.52.46 (talk) 03:38, 19 November 2024 (UTC)

  (Also @Chipmunkdavis) Look at Talk:New_York_City/FAQ for example for some consensus, this has been around for years and solidifies that NYC's climate is subtropical per Köppen. I did not add this. I wasn't even around here when this was added. If you look at the talk page archive, many discussions have been started for this and they have all ended the same way. NYC is subtropical. I'm not representing any kind of fringe opinion, or trying to perpetuate a problem. This is simply how editors have done it, and they have reached consensus many times to do it this way. If you want to change that, per WP:CONLEVEL, you should take this to another venue. Uness232 (talk) 03:51, 19 November 2024 (UTC)

  CONLEVEL does not apply as you have not pointed to a higher consensus. You have explicitly stated the supposed consensus is WP:SILENCE, the lowest possible level. CMD (talk) 03:54, 19 November 2024 (UTC)

  @Chipmunkdavis No, I have pointed out many such instances in the archives of Talk:New York City, a much busier page than this one. See Talk:New York City/Archive 11#Koppen climate classification, Talk:New York City/Archive 14#Humid Subtropical Climate?. There are many MANY other examples from other pages that I can dig up. Uness232 (talk) 04:02, 19 November 2024 (UTC)

  Also Milan, [7] here. Uness232 (talk) 04:04, 19 November 2024 (UTC)

  Those are also isolated article discussions, some back to before we had our current sourcing guidelines! CMD (talk) 04:05, 19 November 2024 (UTC)

  So? I don't understand, why are we making this change only for IoS when this is a widespread problem that can be discussed? Why are we insisting on this talk page, right now? How is that good for the encylopedia? Uness232 (talk) 04:06, 19 November 2024 (UTC)

  I also still don't understand how you think WP:CALC does not apply when the rules of Köppen are provided, CALC literally states:

  Mathematical literacy may be necessary to follow a "routine" calculation, particularly for articles on mathematics or in the hard sciences. In some cases, editors may show their work in a footnote.

  I would say this counts as a hard science. Uness232 (talk) 04:09, 19 November 2024 (UTC)

  Improving this page is good for the encyclopaedia. There is no issue with mathematical literacy here, the issue is applying the classification system without a source, an act which involves zero arithmetic. CMD (talk) 05:28, 19 November 2024 (UTC)

  @Chipmunkdavis How is there no source? I have given you a reliable source with the rules of Trewartha. All you need to do to get from the rules (which are set and unchanging) to a climate type is basic arithmetic, no other sources or interpretation required. Why is this so hard to understand? Uness232 (talk) 11:58, 19 November 2024 (UTC)

  What isn't apparently understood is there is no reason to use Trewartha. Why do you want to use that source which says nothing about the Isles of Scilly on a page about the Isles of Scilly? CMD (talk) 13:17, 19 November 2024 (UTC)

  I don't want to. It's our only option for climate articles. No one writes an academic article for just one location while using an empirical climate classification (Köppen or Trewartha); it's just never done because it's so obvious and everyone can do it with a minute of work, so it will never get published. All we have for Köppen and Trewartha are regional and world maps with rules. We use these rules to classify climates, and then ideally inline cite the rules. This only takes some basic arithmetic. If you want specific sources for specific locations you have to go lower-quality, non-academic, not reliable, and often wrong and outdated. Ask any other editor engaged with this here whether they'd use something like weatherbase.com over an actual academic paper with set, quantifiable rules for climate classification, they will undoubtedly say no.

  As for why we are using Trewartha, it is the second most commonly used climate classification after Köppen. It is used in many academic journals (some of which I have linked here), it has been deemed to represent "zonal characteristics" better than Köppen, [8] and even Britannica leads its article on climate classification article with the terms: "Köppen, Trewartha, Holdridge. It is a commonly used and accepted climate classification with set, verifiable rules. Uness232 (talk) 13:58, 19 November 2024 (UTC)

  This is not a climate article, it is a general article about the Isles of Scilly. If nobody has bothered to write something relating to the Isles of Scilly, then that information probably shouldn't be here. CMD (talk) 14:14, 19 November 2024 (UTC)

  You are being pedantic. What I meant was the climate section on virtually every general article is like this. I have given you 8 examples, you can go into List of largest cities and look for yourself, most of the busiest articles are sourced this way. Logically, do you want all of them removed? Do you want to discuss a general change where sources with climate class rules do not count as reliable sources? (we definitely can do that, but why are we talking about that here?)

  Furthermore, I am explaining to you why virtually no academic journal writes this just for IoS, or any other specific location/city. You ignore my argument again and again and again. Please, for once, WP:LISTEN. Uness232 (talk) 14:24, 19 November 2024 (UTC)

  As I already stated above, OR should probably be removed from this or other articles. We don't need an academic article for climate classification, if that is your argument, I'm not sure why it has come up. If you want to discuss failing to get the point, please don't ask questions I have already answered. To repeat again, I am responding to the specific RfC here, about this particular article. If as you say you don't "want" to use the proposed material, don't use it. That would seemingly solve the dispute. CMD (talk) 14:51, 19 November 2024 (UTC)

  I still do not see how this would be OR, as it can be calculated using basic arithmetic with the inline source given. If no inline source is given then yes, it is OR; but otherwise? Seems WP:CALC to me. This is what I meant by WP:LISTEN; I'm saying that instead of discussing this here about Scilly, maybe we can start a different RfC about whether inline sources with rules should be sufficient sourcing for climate types. I would say yes, as somebody experienced in this, there is no subjectivity or interpretation here; it's just math, but you can argue something else and make your point.

  Also:We don't need an academic article for climate classification, if that is your argument, I'm not sure why it has come up.

  So what do we need? Low quality travel journalism that use their imagination as a method of classification instead of actual rule based classifications that form the basis of ALL of our climate pages (see humid subtropical, Mediterranean etc.) What if that low quality travel journalism doesn't even tell us what classification it is using, and suggests that Paris has a continental climate based on nothing? But when you read the continental climate page, you see no mention of Paris, and realize that, according to Köppen which the continental climate page is based on, continental climates should have a month below freezing, wouldn't you be confused? Wouldn't that seriously harm the encyclopedia? Uness232 (talk) 15:04, 19 November 2024 (UTC)

  Again, picking a climate system is not maths. It is not arithmetic. The maths is, presumably, identifying that there are "8 months of the year with mean temperatures above 10°C", but picking 8 months, picking 10°C, and then picking a classification system are not maths at all. As I have already answered the question I have apparently not listened to multiple times, including the immediately preceding comment, I have no interest in starting a different RfC, and I am responding to this one, about the text on this page. It would not seriously harm the encyclopedia to not include specific climate categories on pages for which we have no sources for their relevance, no. CMD (talk) 15:50, 19 November 2024 (UTC)

  Picking a climate system is not maths, but it is no different than choosing one source over another (or using both!), the same way we present notable historian's opinions, we present the systems of notable geographers. We know the systems are notable because they are used in published research (both Köppen and Trewartha are).

  but picking 8 months, picking 10°C, and then picking a classification system are not maths at all.

  Yes, which is why we have to cite the source for the rules of the climate classification and mention which climate classification we are using. If the climate classification itself is deemed not notable, that is a case by case discussion, but we are not picking anything within the climate classification. We are following the math guidelines in the source according to the set rules of a climate classification. I can only assume that you are not familiar with empirical climate classification at this point, because you are saying that we are picking 8 months. But we are not! Trewartha picked 8 months back in 1958, and we inline cite Trewartha's (or Köppen's) source to show the math that we did.

  Here is an example from Minneapolis:

  Minneapolis experiences a hot-summer humid continental climate (Dfa in the Köppen climate classification).

  This is sourced to Finlayson and McMahon, 2007, which provides the set rules of Köppen on pg. 4 (or 1636 on full original document). With these, and a simple bit of arithmetic, you can see that Minneapolis is in zone Dfa, a hot summer humid continental climate, as mentioned in the source. Now, this would also be problematic if we did not specify which climate classification we are using: but we do! We say, according to the Köppen climate classification, Minneapolis has a humid continental climate. Therefore, simply writing:

  Minneapolis experiences a hot-summer humid continental climate

  even if we use the Finlayson/McMahon source is OR. I accept that.

  But, as long as we:

  • Choose a climate classification that is used regularly in published research and is therefore notable.
  • Cite a source with the official rules of this climate classification, or an official map by the author if the climate classification is genetic instead of empirical.
  • Clarify which climate classification we are using alongside the text.
  • Make sure we have the data to verify on the page where the WP:CALC has taken place.

  This should not be, can not be OR, but rather WP:CALC, because we are explicitly stating which rules we have chosen and proving that these rules are notable by showing reliable sources that use these rules. WP:OR requires that original research be unverifiable. This is entirely verifiable and requires nothing more than a few mathematical solutions and some IF/THEN simple logic. Uness232 (talk) 16:47, 19 November 2024 (UTC)

  Your assumptions are incorrect. As for the rest, choosing a set of rules and carrying out an analysis is what actual researchers do. Bringing together multiple sources, one with rules of analysis and one with a new dataset to reach a novel conclusion is explicit WP:SYNTH. We should not present a historian's opinions about one topic on a different page to that topic. The systems of notable geographers should be presented on the articles covering those systems and geographers. CMD (talk) 17:33, 19 November 2024 (UTC)

  • Your assumptions are incorrect.

  Care to explain?

  • Choosing a set of rules and carrying out an analysis is what actual researchers do.

  If by analysis you mean subtraction and addition, sure; but WP:CALC allows me to carry out basic math "analysis" that is verifiable by a source. Nobody is choosing a set of rules except for the geographers themselves; we are just applying the rules that are in common use; and the application of these rules involve only basic arithmetics, which fall under the basic calculation under WP:CALC. Choosing which system is going to be used is therefore not different from using the opinion of a certain mainstream historical scholar, but not being able to use all of them, which we do not need to do. All we need to do is present viewpoints fairly and with due weight.

  Also, if you think this is WP:SYNTH, what sources do we use for climate pages? And can you find me these sources? It doesn't seem like your proposition makes much sense in an applied, non-theoretical environment. Furthermore, you present this as a 'novel conclusion' but it really isn't. The rules already arrive to the conclusion that according to Trewartha, IoS is subtropical because the rules make the much more general claim that ALL places on Earth with 8-12 months of 10C or above temperature is subtropical. There is no novel conclusion here because there is no analysis: it really is just verbalizing what is already stated.

  Beyond all of this WP:NOTJUSTANYSYNTH and SYNTH is not ubiquitous, is relevant here. Your suggestion would wipe out the climate information on 90 percent of all city pages (many of which are reliably sourced, and can be easily verified by an editor, if you would try for once). Are you sure this is the appropriate way to use WP:SYNTH? Uness232 (talk) 18:08, 19 November 2024 (UTC)

  Okay, sure: [9] (pg.4), [10], [11] (pg. 118), [12] (pg.5). All claim that the only requirement for subtropical is 8 months above 10C. No frost free requirement in any of these.

  At this point, I will need to take a break from this conversation, for a few hours. Feel free to read these if you are not convinced. Uness232 (talk) 04:37, 19 November 2024 (UTC)

  There's nothing in your links to back up your claims that the Isles of Scilly are subtropical or help gain consensus for your fringe theory. And a reminder, your entire argument is predicated on Trewartha's Climate Classification, as described in Trewartha's book in which on page 341 he specifies that for subtropical classifications "marine climates in this category must be frostless". I appreciate this inconveniently demolishes your argument. However, your refusal to seek out and read the source, and instead insinuate it somehow doesn't exist - despite it being quoted in A Level text books and geography curricula around the world - and your persistent resorting to circuitous and unconstructive discussion does lead me to believe that perhaps you are not here to act in good faith. All you needed to do was source your claim... 86.184.52.46 (talk) 04:46, 19 November 2024 (UTC)

  What?

  Sources in order, 1)

  3.2. Group C : subtropical climates

  In the C climate type there must be 8 to 12 months with a monthly mean air temperature of over 10°C and the temperature of the coolest month must be lower than 18°C.

  2)

  In the Trewartha scheme the “C” climate group encompasses Subtropical climates that have 8 or more months with a mean temperature of 10 °C (50 °F) or higher.

  3)

  C: Subtropical climates, 8-12 months above 10°C

  4)

  C: Subtropical climates, 8 to 12 months >10°C

  It does, quote from pg. 3:

  3.2. Group C : subtropical climates

  In the C climate type there must be 8 to 12 months with a monthly mean air temperature of over 10°C and the temperature of the coolest month must be lower than 18°C. The subtypes are again based on the annual cycle of precipitation. Letters s, w and f have similar meaning as they do in the KCC. How- ever, in the KCC, the conditions are not based on precipitation totals during the winter (summer) half- year, but on the amount of precipitation in the wettest (driest) month of the season. Another difference is in the condition for subtypes, which is defined by an average annual precipitation of less than 89 cm, in addition to the driest summer month having less than 3 cm precipitation.

  Doesn't mention Isles of Scilly. 86.184.52.46 (talk) 15:08, 19 November 2024 (UTC)

  Okay, so you purportedly bring a source to the table saying "subtropical climates must be frost-free". It is not a problem for you that Trewartha's book does not specifically say, "subtropical climates must be frost-free, so the Isles of Scilly are not subtropical". But when we counter with the fact that that is NOT Trewartha's rule, your argument is that our sources do not mention IoS. Does your source specifically mention IoS being oceanic because it is not frost-free? Uness232 (talk) 15:22, 19 November 2024 (UTC)

  Thank you for raising this point. I’d like to address your argument step by step to clarify the issue and refocus the discussion on reliable sources and policy adherence.

  === The Role of Reliable Sources ===

  The standard for inclusion on Wikipedia is clear: any material added to an article must be verifiable and based on reliable sources. When making a claim about climate classification, particularly something as specific as "subtropical under Trewartha," the source must explicitly support that classification for the location in question—in this case, the Isles of Scilly.

  If no reliable source explicitly states that the Isles of Scilly are subtropical under Trewartha, such a claim cannot be included.

  === Clarifying the Frost-Free Criterion ===

  The sources I provided are reliable references that define the criteria for subtropical climates under Trewartha, including the requirement for frost-free conditions. This criterion is not an interpretation; it is explicitly stated in these sources.

  • These sources outline general rules for subtropical classifications, which are widely accepted within the framework of the Trewartha system.
  • If the Isles of Scilly are not frost-free, as evidenced by climate data, then the location does not meet the Trewartha criteria for subtropical climates. This is a straightforward application of the classification’s rules—not original research.

  === Your Argument ===

  You are suggesting that my sources must specifically state:

  "The Isles of Scilly are not subtropical because they are not frost-free."

  This is not how Wikipedia’s sourcing works. The criterion for inclusion is not whether a source explicitly states what the Isles of Scilly are not. The question is whether any reliable source explicitly states what the Isles of Scilly are in terms of climate classification.

  So far, there has been no reliable source provided that states the Isles of Scilly are subtropical under Trewartha. The lack of a direct mention in my sources does not make your claim valid; it only underscores that both claims—yours and mine—must meet the same standard of verifiable evidence.

  === Burden of Proof ===

  The burden of proof lies with the editor making the claim. If you assert that the Isles of Scilly are subtropical under Trewartha, you must provide a reliable source explicitly stating this. It is not sufficient to claim it based on your interpretation of climate data or general rules. This would violate the No Original Research policy.

  === Conclusion ===

  To summarize:

  • My sources define the general criteria for Trewartha’s subtropical classification, including the frost-free requirement. This is well-supported and reliable.
  • If you believe the Isles of Scilly meet this classification, you need a reliable source explicitly stating this.
  • The absence of such a source means the claim cannot be included, as per Wikipedia's policies.

  Let’s focus on finding verifiable, authoritative sources to resolve this matter constructively. Any claim must meet the same standard of reliability and evidence. 86.184.52.46 (talk) 16:21, 19 November 2024 (UTC)

  To anwswer your question with sources specifically about the Isles of Scilly, this[13] source discusses the Isles of Scilly, noting specifically that Tropical, not to mention subtropical, plants will grow in the open air only when they are not exposed to very low or great vicissitudes of temperature. Here is a short list of such exotics grown in these islands(p.190) and this source [14] refers to it as the well-nigh semi-tropical Isles of Scilly (p.224), this source[15] says Of course we cannot compete with Cornwall and the isles of Scilly, with their semi-tropical climate (p.429). While I am not sure about its applicability, [16] this guidebook says the gloriously subtropical, unpolluted, and unspoiled Isles of Scilly don't really feel like part of England at all (p.50). Likewise, this book [17] says from the sub-Arctic flow of Country of Caithness or the Caringorms to the sub-tropical Isles of Scilly. This Guidebook published by National Geographic likewise refers to at least some of the Isles of Scilly as a subtropical paradise [18] (p.158). Brocade River Poems (She/They) 06:13, 19 November 2024 (UTC)

  We are looking for reliable sources (RS) to support the claim that the Isles of Scilly climate is subtropical. Unfortunately, none of these sources are valid for that purpose. The first and second sources relate to plant types rather than climate. The third source's use of "well-nigh" suggests it does not quite meet the subtropical threshold. The RHS source is more promising but dates back to 1903, and it is unclear what evidence the claim relies upon. The DK book is a travel guide and therefore not a reliable source for a climate claim. The Max Adams book, while an excellent novel, is fiction and not a reliable source for climate claims. The National Geographic book is somewhat more promising, but the sentence in question is descriptive and does not specifically address climate classification.

  To reiterate, if climatologists accepted that the Isles of Scilly have a subtropical Trewartha climate, you would expect to find this reflected in multiple peer-reviewed papers, studies, and journals over the past 50 years. However, no such evidence has been found. I believe a significant claim such as this requires at least one high-quality, reliable source. The bar should be set high for climate-related claims.86.184.52.46 (talk) 11:04, 19 November 2024 (UTC)

  By this standard of sourcing, no climate page would have a climate type. I understand why a travel guide should be rejected, but if using basic arithmetic on a climate classification with rules that are sourced inline is WP:OR and we want a proper academic source for every city, the Köppen type also needs to be removed, because no academic source will work singularly on IoS and get published. Uness232 (talk) 11:50, 19 November 2024 (UTC)

  Thank you for your perspective, but I think it's important to clarify the standards for reliable sourcing on Wikipedia, particularly when assigning climate classifications.

  1. Reliable Sources and WP : While it's true that many climate pages reference classifications like Köppen or Trewartha, they do so based on reliable sources that explicitly apply these systems to specific locations. Using "basic arithmetic" or making deductions from general rules constitutes original research (WP ), which Wikipedia expressly prohibits. The issue here is not the methodology of the Trewartha classification but the lack of a reliable source that applies it to the Isles of Scilly. Without such a source, any claim about its classification cannot meet Wikipedia's verifiability standard (WP ).
  2. Applicability of Policies: If no academic source directly addresses the Trewartha classification of the Isles of Scilly, then we cannot include such a claim in the article. This ensures Wikipedia reflects published, reliable research rather than editor interpretation. The same standard applies to Köppen classifications—if these are included without proper sourcing, they should also be reevaluated. Consistency across articles is important, but it must be grounded in policy, not assumption.
  3. The Core Issue: This is not about imposing unattainable sourcing requirements but about adhering to Wikipedia's principles of verifiability and avoiding synthesis or unsourced claims. If no reliable source explicitly classifies the Isles of Scilly as subtropical under Trewartha, the claim cannot remain.

  86.184.52.46 (talk) 12:46, 19 November 2024 (UTC)

  Max Adams' book is neither a novel nor fiction, what are you on about? The Museum Of The Wood Age is a nonfiction book by a Historian and Archeologist published by Bloomsbury. You can yell from the rafters about how some book requires something to do with whether or not frost exists all you like, unless it is a source that specifically says the Isles of Scilly are not subtropical, it isn't really applicable. Wikipedia represents what published sources say, which means that if there are a bunch of published sources that say the Isles of Scilly are subtropical, than it can be added to the article. Brocade River Poems (She/They) 12:29, 19 November 2024 (UTC)

  Thank you for pointing this out. While I understand your position, I think it's necessary to refocus on the need for proper, reliable sources in climate-related claims.

  1. Reliability of Sources: Whether or not Max Adams’ book is nonfiction is not the core issue here. The relevant question is whether it constitutes a reliable source (WP ) for the climate classification of the Isles of Scilly. As a book about history and archaeology, it does not meet the criteria for reliability when it comes to scientific climate classifications. Reliable sources in this context must come from climate experts or peer-reviewed publications that directly address the issue.
  2. Misplaced Burden of Proof: The claim that "unless there is a source that says the Isles of Scilly are not subtropical, the claim can stand" misrepresents Wikipedia’s standards. Per WP , the burden of proof lies with the editor proposing the addition. Without a source explicitly stating that the Isles of Scilly are subtropical under Trewartha, the claim should not be included. Absence of contradictory evidence does not justify the inclusion of an unverified claim.
  3. What Wikipedia Represents: Wikipedia reflects the consensus of reliable, published sources—not individual interpretations of data, nor the opinions of editors. If there are indeed “a bunch of published sources” stating that the Isles of Scilly are subtropical, these should be presented and evaluated for reliability and relevance. In their absence, the claim cannot remain.
  4. Verifiability and Responsibility: Claims about climate classifications must meet a high standard of reliability to preserve Wikipedia’s credibility. Allowing unsourced or poorly sourced claims undermines this. If no reliable source explicitly supports the claim under discussion, it must be removed, regardless of how plausible it might seem.
