Reference problems[edit]

@Sunson08, Xiehao.gz, Aprab, and AlexSessions: There is a serious reference issue. Normally I'd revert the edits that have the problem, but with so much editing going on, reverting is impossible. You guys didn't cause the problem, Visual Editor did. Don't copy/paste with Visual Editor as it loves to barf all over the page. This time, it threw up on the refs. You will see refs given as <sup>[[User:Xiehao.gz/sandbox|[37]]]</sup>. Please replace them with the actual ref.

A minor issue, articles are not an outline. Fix the section headers that have outline letters and numbers. For example ====III. Coals==== needs to be changed to ====Coals====.

As Caltech students, I realize some of this is over your heads. You have my condolences on not being worthy or smart enough to be at MIT. As the great MIT meteorologist and faculty adviser might have said, you have too many butterflies flapping in your heads. :)

@Whatamidoing (WMF) and Ian (Wiki Ed): so they are aware.

@Bgwhite: - I see you're making some of these fixes, and I don't want to e/c with you. Would you ping me when you've had enough, so I can finish up the cleanup? Thanks. Ian (Wiki Ed) (talk) 14:30, 26 May 2016 (UTC)[reply]

OK, n/m - the template was telling me you edited it 2 seconds ago, and I was (foolishly)trusting that. Just looked at the time stamps instead. Ian (Wiki Ed) (talk) 14:38, 26 May 2016 (UTC)[reply]

Another VE problem - the automatic reference names suck. Which means that there are multiple refs named ":1". Ugh! Ian (Wiki Ed) (talk) 15:52, 26 May 2016 (UTC)[reply]

Missing ref[edit]

The Atmosphere section includes a reference to Sacese et al., but no full reference is given. Ian (Wiki Ed) (talk) 15:49, 26 May 2016 (UTC)[reply]

Multiple issues[edit]

Multiple points.

I edited a surprisingly large amount of excess verbiage (clutter, i call it) from this article; mainly from the wikicode (i believ in concision, and that applies also for wikicode), but also from the text itself. Okay?
At one point it said that the decay energy of tritium to helium-3 is about 18.6 MeV. In fact, it’s only ~18 keV, according to the source cited. I corrected this.
In the section “Observed variations in isotope abundance”, there is a tag, “This article may require cleanup to meet Wikipedia's quality standards. The specific problem is: δD is used over and over again without being defined; it might also be worth translating into a simpler measure of relative or absolute abundance for less technical readers.” I think δD is the usual δ[isotope] notation (see earlier in the article), with D = deuterium. Still, said term, “δD”, should be clearly defined, with a formula for calculating it, and should in fact be replaced by “δ²H”. IUPAC recommends that deuterium should be called by chemical symbol “²H” rather than “D” (equivalent for tritium, of course). And i myself, dislike calling it by the symbol “D” (see below). In fact, the expression “δ²H” is used earlier in the article; more precisely, “δ²H_VSMOW”.
It said, “hydrogen and deuterium” or “hydrogen or deuterium” (the two terms may hav been in the opposite order). In at least two places, i changed this to “hydrogen/deuterium” or “deuterium/hydrogen”; the wording with “and”/“or” makes it look like deuterium is not hydrogen, when it obviously is. Okay? In fact, i hav come to dislike the practise of giving deuterium a separate chemical symbol “D”, for many reasons; one reason is that it makes it look like deuterium is not hydrogen. But if you write “hydrogen/deuterium”, it looks appropriate: the first term refers to a certain element in general, while the second term refers to a particular isotope of said element. More generally, i feel it is reasonable to write “[term]/[a hyponym of said term]”.
In fact, writing “²H” instead of “deuterium” is not only more concise; it has another benefit: the superscript “2” sticks out, highlighting an important term, and highlighting the fact that here, you ar not only specifying not just an element, but an isotope.
It says, “The study of hydrogen stable isotopes began with the discovery of deuterium by chemist Harold Urey of the famous Miller–Urey experiment.” [Citation deleted.] The part, “of the famous Miller–Urey experiment”, should be deleted; it makes it look like said experiment was about the discovery of deuterium, when in fact deuterium was discovered about 1932, while the Miller–Urey experiment wasn’t until 1952.
