Ice Core
If you find an ash deposition layer from a year in which an eruption destroyed an island that had Camellia sinensis growing on it, you can make a Gone Island Ice_τ.
Title text: If you find an ash deposition layer from a year in which an eruption destroyed an island that had Camellia sinensis growing on it, you can make a Gone Island Ice_τ.

Some people like to taste a wine dated to the year they were born. This comic jokes that paleoclimatologists, who study the climate, use ice instead of wine, drilling into the ground to find the layer matching the birth year of the recipient.

Megan, a paleoclimatologist, decides to make a cocktail with the ice from the icesheets (present in the Arctic and Antarctic, for example). Normally, scientists would try to date the ice and then try to find the state of the climate when these icesheets formed. Here, Megan tries to find the ice layer corresponding to Knit Cap's birth year with the intent of using the ice for a cocktail. The caption asserts that this method of creating drinks is “traditional” for paleoclimatologists. She then asks if Knit Cap has the cocktail shaker that they presumably brought to the site ready. Cocktail shakers are used in the preparation of many mixed drinks, which often contain ice (usually sourced locally).[citation needed]

The title text says that if they manage to find some ash coming from an eruption which destroyed an island with Camellia sinensis growing on it, they'll be able to get a cocktail with tea infused in it, as camellia sinensis is generally used for making tea. Gone Island Ice_τ is a punning reference to the cocktail known in the United States as a Long Island iced tea. It probably also references the IceCube Collaboration's "reported two candidate events for the final unobserved Standard Model cosmic messenger: astrophysical tau neutrinos". Who knew that the rapper and actor was also an astrophysics stud?

Akin to 2729: Planet Killer Comet Margarita, which perhaps needs mentioning in the upcoming Explanation... 162.158.74.118 23:04, 4 March 2024 (UTC)

Added a short explanation, but it'll definitely need more work. 172.70.210.235 23:11, 4 March 2024 (UTC)

The title text raises a lot of questions. It's a play on the mixed drink Long Island Iced (or Ice) Tea of course. But why the underscore? Why does the T look funny (tau?)? Why isn't tea spelled out?172.69.6.189 23:44, 4 March 2024 (UTC)Pat

Yes, Randall did use tau in the title text. I recently made mention of that in my most recent edit. I'm not sure why he used it but maybe instead of a "Gone Island Ice Tea", it's a "Gone Island Ice Tau"? OmniDoom (talk) 23:58, 4 March 2024 (UTC)

Tau is tortuosity in a lot of equations involving porous material (including ice), and also represents time in some engineering disciplines. It's written as "Ice_τ", and I have no idea what the oddly specific underscore is. Maybe it's "I x c x e" from some equation that involves τ? And somehow could be relevant to a sunken island? 172.69.58.152 00:05, 5 March 2024 (UTC)

It could be the case that the underscore before the tau is indicating a subscript and that, as you said, the "Ice" could be "I * c * e_τ" but I have no way of being sure. (Quick aside: I originally read the "I x c x e" expression as though it were "Ixcxe" and took it for a word or an acronym or something. Humanity really needs to agree on a universal form of multiplication sign for typing.)OmniDoom (talk) 00:28, 5 March 2024 (UTC)
Aside cont.: We already have a character specifically for this: × (U+00D7 MULTIPLICATION SIGN). How to type that is an exercise left to the reader. 172.68.19.94 01:01, 5 March 2024 (UTC)

I've heard recently (possibly reheard, as (amongst other things) I've been relistening to The Infinite Monkey Cage broadcasts/podcasts but can't immediately pin down the remembered context) about ice-core samplings having been used as drink-ice. But this is thousands-of-years-old ice, with thousands-of-years-old atmosphere trapped in it, as bubbles that get released as it melts. It was supposed to be special, given that (with a bit of poetic licence) you could technically breath in the ancient atmosphere with a good sniff at the glass. Though, as might not be surprising, the taste was described as "like drilling fluid". 172.69.195.156 02:24, 5 March 2024 (UTC)

Is it really possible to date ice layers to specific years? I assume dating precision is millenia, maybe at best centuries. The explanation should mention how impossible it is to date to a specific birth year, unless there happened to be a specific climatologic event that year (like a big eruption). Barmar (talk) 02:54, 5 March 2024 (UTC)

If compressed (centuries or more of snow atop), it might be more difficult, but this is going to be maybe a handful of decades of layers. Depending upon the local buildup method (still snows a bit during the long (ant)arctic night, then (ant)arctic day gentle crisps the surface snow), it might be fairly obvious under visual inspection. Even without key marker deposits from atmospheric dust/soot/etc. But would depend upon both weather and climate patterns. 172.69.194.242 04:39, 5 March 2024 (UTC)

" ice (usually sourced locally).[citation needed]" Up until just about a hundred years ago, most ice in the eastern US came from Maine. In winter the Mainers sawed-up the ponds, stored ice in sawdust-filled ice-houses, then in summer shipped it as far south as Cuba. --PRR (talk) 05:23, 5 March 2024 (UTC)

While the ending pun on the name of actor/rapper "Ice Cube" is funny (as would be a more elaborate pun also involving Ice-T), I think it detracts from the explanation, actually making things more confusing. Mathmannix (talk) 11:54, 5 March 2024 (UTC)

Can anyone identify the specific geological event Randall refers to? When did a Volcano destroy a tea plant producing island? 172.70.230.169 11:57, 5 March 2024 (UTC)


I think I have answered my own question... This is the google search results:

Has a volcano ever destroyed an island? The 1883 eruption of Krakatoa (Indonesian: Letusan Krakatau 1883) in the Sunda Strait occurred from 20 May until 21 October 1883, peaking in the late morning hours of 27 August when over 70% of the island of Krakatoa and its surrounding archipelago were destroyed as it collapsed into a caldera. 162.158.155.53 12:00, 5 March 2024 (UTC)

An aside: Though I don't know if it was intentional on Randall's part, there is an additional pun to Ice_τ: In German 'Tau' is not just the Greek letter, but also the word for 'melt' - which does fit the comic's theme. 172.69.150.94 13:59, 5 March 2024 (UTC)

About the _τ, some times programs (like Desmos) use underscores to portray subscripts, which may be the intent here --172.70.230.155 19:47, 6 March 2024 (UTC)

I think this is a clear reference to the weel known anecdote in the paleoclimatologist community. Claude Lorius was drinking a glass of Whisky on an Antarctic base when he noticed that air bubles trapped in the ice could provide key information on fomer climatic conditions. After a quick search, here is a reference citing this anecdote [1]. Sapin (talk) 21:51, 6 March 2024 (UTC)

It would not surprise me if Rat from 'Pearls Before Swine" was on his way over with a baseball bat to have a "word" with Randal about puns. These Are Not The Comments You Are Looking For (talk) 01:24, 12 March 2024 (UTC)
