Draft:Verified for Climate. Please help, thank you! Hidden anonymous editor (talk) 08:46, 19 June 2025 (UTC)[reply]

Hello @Hidden anonymous editor. Thanks for your contributions!!

Reviewers will want to see there are at least three sources that are reliable, independent and secondary. You can help them by providing more details on the sources you've cited. Who was the publisher? What's the translated title? —Femke 🐦 (talk) 18:08, 19 June 2025 (UTC)[reply]

An editor has extensively edited Ocean heat content, introducing tracts of unsourced technical detail in what was formerly geared toward readers of this layperson's encyclopedia. I want to avoid an edit war (see Talk:Ocean_heat_content#Definition_of_heat), and I urge project members to weigh in there. —RCraig09 (talk) 20:06, 20 June 2025 (UTC)[reply]

The alleged "unsourced technical detail" is basics in thermodynamics, written in a separate section, with several links to the wikipedia articles of thermodynamics.

The lead section, which RCraig09 doesn't like, reads:

============================================ (START)

Enthalpy taken up by oceans

Ocean heat content (OHC) or ocean heat uptake (OHU) is the enthalpy absorbed by oceans, and is thus an important indicator of global warming.^[2] Ocean heat content is calculated by measuring ocean temperature at many different locations and depths, and integrating the areal density of a change in enthalpic energy over an ocean basin or entire ocean.^[3] Despite being called heat content, “work and heat are not stored in a system. Each is a mode of transfer of energy from one system to another,”^[4]. Historically, in the 19th century, the now obsolete notion “heat content” was used in thermodynamics for enthalpy and denoted by ${\displaystyle H}$, see the section about history and etymology of enthalpy, and see also the section Critics and possible misunderstandings.

This wikipedia article

• provides the present definition,
• explains measurement methods,
• discusses causes for heat uptake and
• expected impacts.

============================================ (END)

The problem seems not to be alleged "unsourced technical detail" or the like, but just the issue, that some people lack basics of thermodynamics and do not know, that no system stores work or heat. This, however, is a fact in physics! Systems store energy (and mass). Heat is not a quantity associated to a state. Heat is associated to processes. The idea of an "amount of heat stored" was a point of view till around the mid of 19th century, but meanwhile, it is known in physics, that such an amount does not exist in a volume and this point of view is obsolete. Heat is just some mode of energy transfer, associated to processes. That's basics in thermodynamics. That's even very elementary basics, but might come to some as a surprise.

Ocean Heat Content (OHC) is an enthalpy (dependent on the context: per area, per volume, or total) and therefore a notion of energy.

This is also clarified in the original articles about TEOS-10 , e.g. the official TEOS-10 manual section 3.3, or in the wikipedia article Conservative temperature, and in the basic literature about maritime research.

Before talking about OHC, one first should understand, what OHC is and what it means in thermodynamics. One should guard against possible misunderstandings! OHC is not a kind of stored heat (which simply does not exist in physics), OHC is not internal energy, and OHC is not temperature. OHC is an enthalpy uptake.

As a result of that uptake, for instance, temperature might rise (but also entropy).

Please keep discussion in one place at Talk:Ocean heat content. —Femke 🐦 (talk) 10:19, 21 June 2025 (UTC)[reply]

Through the talk page of the climate change template, I became aware of Air conditioning paradox, a new article. I have questions about the article's title and its notability. See the article's talk page if you have an opinion on this that you'd like to share. EMsmile (talk) 13:17, 1 July 2025 (UTC)[reply]

boldly merged to Air conditioning#Environmental effects but as I did not discuss someone may unmerge

100,000-year problem has been nominated for a good article reassessment. If you are interested in the discussion, please participate by adding your comments to the reassessment page. If concerns are not addressed during the review period, the good article status may be removed from the article. Z1720 (talk) 19:58, 13 July 2025 (UTC)[reply]

That's not how the comic says this should go. Relatedly, should wikidata include "Also known as: climatic variation, climate variability, climatic change"? The first two don't seem accurate at all, I would intuitively suggest they refer to other topics. Ghits on the third mostly refer to a scientific journal. CMD (talk) 03:17, 17 July 2025 (UTC)[reply]

Climate variability is usually about shorter time scales, whereas climatic changes are about longer timescales. There is a large bit in the middle where some scientist call something variability while others call it climate change, depending on what they're studying. So not synonymous, no. —Femke 🐦 (talk) 21:57, 17 July 2025 (UTC)[reply]

Hi Anthere. Welcome to the Wikiproject, and lovely to see this project take shape! Could you give an example of what you mean by visualising knowledge gaps? You might be interested in the Wikipedia:WikiProject Climate change/Figures page, an inactive project that sought to improve and update climate change data visualisation across the board. More recently, TatjanaClimate has been working with various organisations to release climate-related media onto Commons. —Femke 🐦 (talk) 21:00, 1 September 2025 (UTC)[reply]

Hi Anthere, good to see you here. To be honest, I have tried to understand the page you linked to and I don’t feel like I’m getting it. There is a participatory design process, but what is it designing? Are there examples we can see of what similar research projects have designed?

I am also curious about “ According to the results of our preliminary project, volunteers need their curiosity to be stimulated…” where can i resd more about this preliminary project? Clayoquot (talk | contribs) 08:00, 9 September 2025 (UTC)[reply]

"So far, most of the campaigns manually curate lists of articles every time, going through article by article to assess quality, and often without being able to compare across different linguistic editions of Wikipedia easily." That sounds where we are and generally have always been. I am curious to see the ideas underlying making such curation more accessible and visual. I know Wikidata captures GA and FA equivalents across wikis, unsure if SPARQL can get more granular assessments. CMD (talk) 09:37, 9 September 2025 (UTC)[reply]
