Scandinavia south of Paris.

The world will be covered with a whole new set of life forms, humans will be long gone, and there will be no evidence that we ever existed.

They'll be fossils and a band of pollution akin to the oxygen catastrophe.

It's good to know Brexit is only temporary.

Pacific Ocean feeling pretty smug right now about maintaining its status as the largest ocean.

[–] LovableSidekick@lemmy.world 2 points 2 hours ago (1 children)

And the Pacific Rim? It's the only rim, baby!

[–] PodPerson@lemmy.zip 1 points 2 hours ago

And it goes aaaaaaaalllll the way ‘round.

[–] DarkFuture@lemmy.world 7 points 6 hours ago

We aren't going to be around to see it. Shit, the way we're doing things nothing else will be around to see it either.

The worldbuilder in me sees a land of intelligent animals who live in a land strewn across with ancient human ruins.

[–] aamram@lemmy.dbzer0.com 17 points 8 hours ago (2 children)

Apparently New Zeland is still off the map... Just like nowadays.

[–] OhStopYellingAtMe@lemmy.world 3 points 2 hours ago

New Zealand is the Gen X of countries.

As it is written in the ancient texts.

[–] JillyB@beehaw.org 9 points 8 hours ago

"The South will rise again" folks were right. They just had a much longer timeline than we imagined.

[–] OmegaLemmy@discuss.online 39 points 11 hours ago (1 children)

fyi there are many proposals for future continents, it's basically unknowable

[–] Harvey656@lemmy.world 6 points 7 hours ago (1 children)

Sure, but its fun to speculate!

[–] blackbrook@mander.xyz 1 points 5 hours ago (1 children)

The English language has words and grammar for speculation, "will" is not one of them.

Sorry I was being unecessary obnoxious. I just meant they could have written it saying "this could happen" rather than presenting it as "this will happen."

I'm just really triggered lately by everything online being exaggerated for clicks.

[–] absquatulate@lemmy.world 9 points 8 hours ago (1 children)

Tamriel! Or at least Cyrodiil+Elsweyr

[–] Swedneck@discuss.tchncs.de 5 points 7 hours ago

this made me realize how great this map would be for an alternate history or fantasy setting

the mountain range between north america and africa creates the super interesting situation where the sides are almost entirely separated save for the coast and a teensy tiny bit near cape town that's sort of crossable, so the coast would see an insane amount of traffic and i could see there being a capital nestled in the mountains next to the passage to cape town.
And of course the indian ocean would be where basically everyone lives, as others have said.

[–] moakley@lemmy.world 36 points 12 hours ago

I guess no point in climbing Mount Everest if it's not going to be the tallest in 250M years. That's a relief.

[–] modifier@lemmy.ca 14 points 10 hours ago

Solves the Florida problem at least.

[–] ekky@sopuli.xyz 64 points 13 hours ago (2 children)

Imma use this as world map for my next Pen&Paper campaign.

[–] Skua@kbin.earth 18 points 11 hours ago (1 children)

Numenera is actually (mostly) set on a far future Earth in which the continents have moved to form a new ~~pangaea~~ supercontinent. It's actually way too far in the future for it to be this one, and there has been a whole bunch of continent-scale terraforming at some point, but still!

[–] atomicbocks@sh.itjust.works 10 points 10 hours ago (1 children)

Pangea is the name of only one supercontinent. The others have other names.

[–] Skua@kbin.earth 4 points 8 hours ago

Good point! I think I saw the name "Pangaea Proxima" and forgot that they weren't all variations on that

[–] ghost_towels@sh.itjust.works 6 points 9 hours ago

That’s exactly what I was thinking! Going to save it for my daughter’s games.

[–] jaybone@lemmy.zip 40 points 12 hours ago (3 children)

I thought the pacific was getting smaller and the Atlantic was getting larger? I would expect the America’s to meet with east Asia.

[–] Quantumantics@fedia.io 26 points 11 hours ago (2 children)

This scenario is one possible projection; it assumes the eventual development of a subduction zone in the West Atlantic that would overcome the spreading at the mid Atlantic ridge, eventually sealing the basin. I don't understand the mechanisms well enough to know how that prediction was made, so someone with more experience on the subject can chime in.

[–] wolframhydroxide@sh.itjust.works 5 points 5 hours ago* (last edited 1 hour ago)

I'm, unfortunately, likely in the same boat, as far as expertise is concerned. I have a degree in geochemistry, and I agree with your analysis of the assumptions made to produce this model, but all of the projections I've seen until this one suggested the closing of the pacific basin.

Consider that much of the pacific mid-ocean ridge (the only thing preventing the closure of the pacific basin) is already being actively subducted under the eastern pacific boundary. Think about that: the spreading boundary itself is being subducted. This makes one wonder how it would be conceivable that the pacific basin widens in the future, despite the vast majority of the world's active subduction boundaries being along the pacific rim.

[–] Sc00ter@lemmy.zip 9 points 8 hours ago (1 children)

Im gonna guess, from your response, you have the most experience on the subject of anyone we will find in this thread.

[–] ramble81@lemmy.zip 17 points 12 hours ago

Okay. Glad I’m not the only one and I can’t believe I had to scroll so far.

From what the wikipedia page tells, under this hypothesis atlantic will stop widening in about 125 millions years, and begin to shrink.

[–] wise_pancake@lemmy.ca 49 points 13 hours ago (2 children)

The mongols would rule the shit out of this supercontinent

Americans still won’t want to visit anywhere else…

[–] burgerpocalyse@lemmy.world 4 points 8 hours ago

LOOK OUT! AAAAGGHHHH

[–] IAmNorRealTakeYourMeds@lemmy.world 14 points 11 hours ago

Imagine the high speed rail network 🤤

[–] zaphod@sopuli.xyz 21 points 12 hours ago (3 children)

It's comforting to see that the large cities will still exist in 250 million years.

Florida stuck it in Africa and made the new highest point.

[–] Donkter@lemmy.world 9 points 11 hours ago

Cradle of civilization is going to be lit around the Indian ocean. It's like a super Mediterranean.

[–] fxomt@lemmy.dbzer0.com 21 points 13 hours ago (4 children)

what the fuck where is the middle east, did we get erased ??? ^/s^

[–] HasturInYellow@lemmy.world 23 points 13 hours ago (1 children)

It's, strangely, pretty much where you left it, right between India and Africa.

[–] fxomt@lemmy.dbzer0.com 16 points 13 hours ago

lmao I kind of see it now, it appears the Arabian peninsula is no longer a peninsula but a tiny bump. Oh well good to know I wasn't erased

[–] Skua@kbin.earth 12 points 13 hours ago (1 children)

The prediction here is that Africa moves westward, squashing the Arabian peninsula into the south coast of the Iranian plateau. The Arabian peninsula becomes the coastline between India and Africa
