Talk:1225: Ice Sheets

The original paper [1] Sebastian --178.26.118.249 07:38, 14 June 2013 (UTC)

It is commonly stated that EVERY sequel is worse that the original film (exceptions are few and often disputed). And very few producents are able to stop filming sequels sooner that they produce sequel worse that all previous. If you see a series with every film better that the previous, then producent is already preparing next one ... or died. -- Hkmaly (talk) 09:20, 14 June 2013 (UTC)

• However, going to the bottom of the Wikipedia page for Ice Age shows that Rotten Tomatoes strongly agrees that the sequels were not better Odysseus654 (talk) 16:34, 14 June 2013 (UTC)

For those of us who do not live in one of these four cities, does anyone have a more comprehensive set of data for the rest of the continent? Or specifically NYC? ;)

Striations on the rocks in Central Park are evidence that a glacier did reach as far south as New York City and in the referenced article on page 21, Figure 4 shows a map of the extent of the glacier just reaching NYC and Long Island and is labeled as somewhere between 0 and 600 meters thick. This page on the City of New York Parks and Recreation site [2] says the glacier in NYC was about 1000 feet thick which is about 300 meters. I should add that the Freedom Tower being built on the WTC site will be 1776 feet high (counting the broadcast antenna) and the Empire State building is 1454 feet high, so some of the current buildings would have poked out of the ice.

Was just curious, is this a jab at "Global Warming" and the fact that Glaciers have always been melting and getting thinner?--65.215.93.238 13:36, 14 June 2013 (UTC)

I don't think so, just because someone finds it amazing how deep the ice during the last glaciation was, doesn't imply anything about their opinion on the causes of changes in climate over the few centuries. By the way, the glaciers have melted and refrozen lots of times, they haven't always been melting.NHSavage (talk) 18:44, 14 June 2013 (UTC)

Global Warming

The actual climate discussion is still not solved. But we do know very well that the ocean sea level was 130 Meters lower than today at that time. At the end of that period the sea level was growing fast, but then it did raise slower later, and that raise didn't stop until today. Randall is only showing ICE levels, not more.--Dgbrt (talk) 22:17, 14 June 2013 (UTC)

I've read and re-read both comic and explanation (and, moreover, the above comments) and I just can't agree with the current third and final paragraph of the explanation ("But the joke ... (see Sea level rise)."). It is, to my mind, merely interesting that at a time of ice-age there was far more depth of ice pressing down upon sites than there currently are famous heights of buildings above the present day, and ice-less, horizons at these particular locales, as depicted. The sole joke, to my mind, is in the title-text, with the direct swapping of the common Ice Age film series's prefix for the souce paper's title. (Which is jolly funny!) And is in line with some of Randall's other largely "informative" strips, jokes sneaking in only as captions and labels.

It is indeed also interesting to note, as a side-issue, that glaciation (and thus deglaciation) relates somewhat to sea level (but note also Post-glacial rebound as a significant effect in some areas, both reinforcing and opposing sea-level changes, depending on locale). However, there's not even any mention of relative sea-level in the images. This could perhaps have been implemented as an arrow tacked onto the side of each depth-extended cross-section, pointing base to point (or vice-versa) between the axial position of the historic Mean Sea Level (if known) and that relating to the current state of affairs, in perfect scale against the column of sky-line and ice. But right now there's no reference at all to support this thought, and thus hardly asks for any such 'explanation' or reference. (There's similarly no invocation of the "climate discussion", unsolved or otherwise, outside of our combined commentary on the comic.)

Mayhap are people being confused by the (admitedly) water-like appearance of the depiction of ice-layer? Possibly thinking that these diagrams are of submerged cities (a la representations in various /The Day After Tomorrow/, /A.I. Artificial Intelligence/ or /2012/-ish films), not ones figuratively transplanted back back into the ancient ice-mass... Or are people inadvertently trolling their personal pro/anti-Climate Change views here (esp. w.r.t. Human impact)? Perhaps subconciously reading more (potentially pro- or anti-!) into the comic than (so far as I can see) was ever intended. If you'll forgive my hopefully 'neutralist' stance on the issue (i.e. divorced of my semi-moderate stance on the issue, which is in whatever direction it is that I lean... but which I have deliberately tried to have kept unstated).

Add to this that Randall shows only Leftpondian locations (and upper-Leftpondian ones, at that, due to the specialised scope of the source paper) this also makes me wonder why Europe and Asia are mentioned in that para, (unless it's meant to say "Ice Ages didn't just happen to North American, but also to similar latitudes in a circumpolar fashion", in which case could we also add anything we know about the southern hemisphere as well?). But that's a minor niggle I have in a paragraph that (obviously, from the length I've been taking pains to discuss all this within) I just can't get a handle on in the first place. But perhaps I'm missing something so, rather than editing and excising the main article, here I ramble on about it. Perhaps to pursuade some prior contributor to re-explain their particular contributions. (We now return you to your regularly scheduled programme...) 178.107.249.215 22:32, 16 June 2013 (UTC)

The end of the explanation

It seems to suggest that the comic shows European and Asian glaciers, which is ... clearly false. What's that bit about?

Well maybe that's Boston, Lincolnshire or Montreal, Catalonia. Or even the respective ones in the Philippines/Jordan. But I still doubt it. ;) Anyway, as per the TL;DR; mess of my prior comment 'contribution' I still don't like that ending. But that could just be me misreading. 178.107.249.215 11:49, 17 June 2013 (UTC)
