If you are not a Wikipedia editor, you can add reliable sources (RS) below and an editor can contribute to the article. (You can become an Wikipedia editor!) If you personally disagree with the concept of climate change in general, this talk page is not the place for that, even if your own personal reasons are really good. However, if you have a specific RS that mentions the Special Report on Global Warming of 1.5ºC, please add it below, even if it is critical of their findings. The reliable sources we use can express criticism. They can be biased or against the topic of the article. However, every editor that contributes must ensure that their contribution to this article and others, is neutral, and does not reveal the editor's personal bias.

Info box

Is this the right info box? There is a template problem with it. Thanks. I am also attempting to create a related WikiNews item and I would like to have it looking acceptable. Oceanflynn (talk) 18:14, 8 October 2018 (UTC)

@Oceanflynn: That's a citation template you've used, it will not produce an infobox. Infoboxes are optional, there's no need to have one on this article.

Thanks jmcgnh I removed it.Oceanflynn (talk) 20:23, 8 October 2018 (UTC)

Other advice: the list of contributors can be found in the report, there is no need to reproduce it here. If one of the press reports makes particular mention about one of the contributors, you could discuss their participation in that context. — jmcgnh^{(talk) (contribs)} 19:02, 8 October 2018 (UTC)

I am considering creating an article: List of contributors to RS15 re: similar articles for previous IPCC reports.Oceanflynn (talk) 17:38, 10 October 2018 (UTC)

I'd like to keep it for now because it has names of scientists who already have Wikipedia pages. Can I hide it? Do you know the template for that? I may also put it in the talk page. Thanks again. Oceanflynn (talk) 20:23, 8 October 2018 (UTC)

Missing space between numerical value and unit symbol in article title

I just added a space between "1.5" and "°C" throughout to comply with WP:MOSNUM. The title still needs correcting but I don't know how to fix that. Dondervogel 2 (talk) 20:54, 12 October 2018 (UTC)

@Dondervogel 2: Good catch. I moved the page to the new title. As far as I know it's not possible to insert nonbreaking spaces into articles titles themselves, so links to the page should now be formatted like this: [[Special Report on Global Warming of 1.5 ºC|Special Report on Global Warming of 1.5{{nbsp}}ºC]]. —BLZ · talk 21:49, 13 October 2018 (UTC)

Main Statements: Use of "This report"

In the Main Statements section, I don't think we should start off with text like "This report" or "According to this report." I think it's understood that the whole article is about the report. Musujyay (talk) 17:35, 19 October 2018 (UTC)

Current Article Title is Technically not Using the Correct Degree Sign

The current title of this article uses the the (º) character to represent degrees. However, this character is actually º and is the "masculine ordinal indicator", not the degree sign. The degree sign (°) is ° and is used throughout the article itself. Should the article title be changed to use the degree sign? I do not think that this is a technical limitation of Wikipedia titles, but rather inconsistency in how we each write the symbol.

For now, I have created a page with the same name but using the degrees symbol (Special Report on Global Warming of 1.5 °C) and made it redirect here to this page. Perhaps it should be the other way around? ChromeGames923 (talk) 17:46, 21 October 2018 (UTC)

• @ChromeGames923: Great catch, thanks for pointing this out. I've moved the article so that the title uses the degree symbol. —BLZ · talk 23:13, 15 November 2018 (UTC)

I'm in awe Skinnytony1 (talk) 23:29, 15 November 2018 (UTC)

Its broad findings are reported as being that drastic action must be taken?

This is dubious in the lede: "Its broad findings are reported as being that drastic action must be taken". It may well be true that it is being reported as such, but it doesn't appear to be true that the report does so. The headline statements [1] contain no recommendations, and certainly no use of the word drastic William M. Connolley (talk) 06:50, 24 October 2018 (UTC)

I agree that that statement misrepresents the findings of the report itself. A change that better reflects the tenor of the report has my support -- Jmc (talk) 09:01, 25 October 2018 (UTC)

Perhaps a change of wording to use wording from the accompanying press release which states "Limiting global warming to 1.5oC would require rapid, far- reaching and unprecedented changes in all aspects of society"[2] and the summary for policy makers states "Global net human-caused emissions of carbon dioxide (CO2) would need to fall by about 45 percent from 2010 levels by 2030, reaching ‘net zero’ around 2050".[3] The quantitive changes required for the climate to be stabilised at or below 1.5 degrees could be defined as "drastic" but "far-reaching and unprecedented changes in all aspects of society" is less ambiguous. What do you think? Skinnytony1 (talk) 23:20, 25 October 2018 (UTC)

@Skinnytony1 : good suggestion; has my support. The first part of the sentence ("Its broad findings are reported as being that") could be better worded - perhaps along the lines of "The report forsees". -- Jmc (talk) 08:42, 26 October 2018 (UTC)

Improved citation

The following citation markup is preferable to that currently used (in my opinion). Those working on this article might like to transfer it? RobbieIanMorrison (talk) 19:04, 19 August 2019 (UTC)

The ":0" refs were redundant, and the sfn refs were not working properly. Now they should be OK. The source is at Wikidata - there are still authors (editors) to add to both the summary and the full report. Boud (talk) 04:21, 5 December 2023 (UTC)

Potential error in the order of percentages?

This sentence

"580 GtCO2 and 420 GtCO2 for a 66% and 50% probability of limiting warming to 1.5 °C, using global mean surface air temperature (GSAT); or 770 and 570 GtCO2, for 50% and 66% probabilities, using global mean surface temperature (GMST)"

is a bit confusing. Surely the 580 GtCO2 refers to the 50% probability and the 420 GtCO2 refers to the 66% probability, as in the less carbon you emit the more likely you are to limit the warming. The GMST probabilities in the second half of the sentence support this reading. — Preceding unsigned comment added by 82.16.143.128 (talk) 15:15, 29 November 2019 (UTC)

You're right, these probabilities were swapped w.r.t what was written in the source. Fixed, thanks for noticing. Tokenzero (talk) 18:14, 1 December 2019 (UTC)
