Names of glacial events

I have made an edit to point out that the names used in this article are those used in Great Britain, with a pointer to the "Timeline of Glaciation" for other names. As these vary widely from place to place (and probably also ought to be linked to Pluvial/InterPluvial names), this is a necessary caveat.--APRCooper (talk) 14:27, 21 December 2007 (UTC)

Sorry, but I've reverted you. The names used on this article are the actual names of the articles on Wikipedia. Some are indeed the names used in Great Britain, but not all of them. ~ UBeR (talk) 19:19, 21 December 2007 (UTC)

OK, I see why you've reverted me. But it is still the case that the names of glacial periods are only valid locally and are not necessarily synchronous with periods elsewhere, so perhaps a note clarifying this should be added. Glacial chronology and stratigraphy is a complex matter; we need to make this clear while retaining the essential information. Ideally we should use ice core or abyssal stratigraphy as the basis for encyclopaedic classification, with links to local stratigraphic units as required. However, that would need a rather extreme tidying up of the articles! --APRCooper (talk) 20:55, 1 January 2008 (UTC)

Indeed it would... ~ UBeR (talk) 00:21, 2 January 2008 (UTC)

Vikings

Removed the following as unsourced and perhaps misplaced.

==Early Vikings==
The vikings were greatly affected by how the glaciers formed their surrounding environment. These geological evidences comes in various forms, including rock scouring and scratching, glacial moraines, drumlins, valley cutting, and the deposition of till or tillites and glacial erratics. Einar Ostmo, a norwegian geologist suggested in 1978 that the drumlins played a central role as their religion developed further. Furthermore, this evidence was difficult to date exactly; but only years later Ostmo found in cooperation with the German archaeologist Georgius Agricola further evidence that reflected this. Drumlins were a sign from the God Rån, that the ares was habitable land. So the glaciation had a huge impact on the location of early viking settlements.

It is interesting, but needs references and perhaps we need to find a better article for it. Vsmith (talk) 14:19, 21 August 2011 (UTC)

If refs can be found, the Last glacial period section Weichselian glaciation, in Scandinavia and northern Europe would be a better home. Or maybe Nordic Stone Age (just discovered that one:). Vsmith (talk) 14:33, 21 August 2011 (UTC)

Chart of Composite CO2 record

Chart of Composite CO2 record, first chart of the article, appears next to "Quaternary ice age" and "Last glacial period." The chart perplexed me when I tried to relate it to the years discussed in the article. Also I feel the chart would be more helpful to me if it identified when earth was glacial and interglacial, rather than my having to try to figure it out. Thanks to anyone who may improve this. — Preceding unsigned comment added by Betweendust (talk • contribs) 20:10, 13 February 2019 (UTC)

Quaternary glaciation

This article focuses so much on the Quaternary glaciation that it is little more than an inferior version of that article. I do not propose a merge; I propose that subject matter experts rewrite this article to focus on "glacial period" as a general earth sciences concept and not so much on the recent unpleasantness. I will do what I can myself, but I am not a subject matter expert on glaciations.

Questions this article should answer for the reader:

What is the cyclicity of a glacial period? (Touched on in lead; should be elaborated.) Is it the same in previous ice ages as the current ice age?

What is the signature of a glacial period in the geologic record? Including: what signatures do previous ice ages (pre-Quaternary) have?

What are the physical causes of a glacial period?

Some of this is touched on in related articles and I'll try to consolidate that here, using their reliable sources, but, as I said, I'm not actually a subject matter expert. --Kent G. Budge (talk) 21:22, 11 October 2020 (UTC)

There are prehistoric glacial events, like Snowball Earth and the Late Paleozoic icehouse in southern Gondwana, but for such remote antiquity there's not really a record of glacial interglacial cycles as we would imagine for the Quaternary. Hemiauchenia (talk) 00:49, 14 October 2020 (UTC)

As I was writing this I came across the Permo-Carboniferous article, is this better merged somewhere? Hemiauchenia (talk) 00:49, 14 October 2020 (UTC)

Been on break (looking at rocks for a week, actually.) I'll take a stab at salvaging this article as soon as I've written up my adventures. --Kent G. Budge (talk) 04:20, 18 October 2020 (UTC)
